Rev OI to Rev A Changes:
1. Not documented.
How to convert Rev OI to Rev A:
1. Not possible.
Rev A to Rev B Changes:
1. This update was to change TED paperwork to latest standards.
2. No PCB or schematic changes.
3. REV, ASY, OPT, TOP pages added.
4. The BOM for the board, minus sensor, moved to -001 (from -000).
This was done to fit into the "no -000 assembly" method of multiple
build option demo boards.
How to convert Rev A to Rev B:
1. No changes necessary.
Rev B to Rev C Changes:
1. Assembly Instructions fixed:
Step 5 had RJ installed as 0.125" and 0.25" in error.
Changed to be 0.125" installation height.
2. No other changes.

2. This sticker may be applied onto the top of the board, if it can be.
If the sticker is topside, it shall be located between U1 and the
silkscreen text "Current Sensor". This is if it will fit, without
overlaying any silkscreen text or solderpads.
If the sticker is larger than that area, the sticker shall be located
on the backside of the PCB.
3. Any sticker applied by the assembly house (not of the type above) shall
be installed on the backside of the pcb.
[This may be a tracking number, or the assembly house P/N.]
The label shall not cover any holes used for soldering.
4. The Allegro sensor may be installed at any time.
That is, all the parts required to build an 85-0322-010 (for example)
may be installed at the same time.
5. RJ: 22g jumper.
Use 22g buss wire, 0.5 inch body, with 0.25 inch leads bent 90 degree.
Install 0.125 inch above PCB (not critical).
Solder and trim.
This component will be used for scope ground clips.
0.5" LS
0.25" leads
Intial bending:
0.125" above PCB
6. It is recommended that the SMT parts be installed first, then thro-hole,
then banana jacks and standoffs, lastly the sticker(s).
Any order of operations may be performed, however.

BOM Explanation
Item: each distinct component has a "line item" (but may span multiple lines). When questions arise to a component parameter/designation/etc, please
refer to line item number first when inquiring.
QTY: the quantity of items to be ordered per finished assembly. Note: higher level documents may call this BOM multiple times
S: BOM Substitution Instructions. See below
Manufacturer: Recommended (or required) Manufacturer for the part(s). Note: multiple manufacturers may be listed per line item.
Note: if no manufacturer part number is given, the the item is considered generic enough that that any manufacturer should work. Ie, 1N4001 in
a DO-41
P/N: The manufacturers part number. Note: if multiple manufacturers are listed, this P/N will correspond only to the manufacturer to the immediate left
of the P/N
Note: Manufacturer part number may be incomplete; if not enough information is given, see below.
Description: this is a generic description of the part. Package size, part type, minimum/maximum requirements are listed.
Note: this is generic and may not exactly reflect the suggested/required part. For example, "capacitor, 25V" while the manufacturer P/N
is actually 50V. The capacitor is required to a minimum of 25V rated (important only if second sourcing)
Ref: This is the list of component designators.
If "see construction notes" is listed, the construction notes must be used to determine component location (not marked on board etc)
Note: surface mount components may have a designator listed but not marked on PCB silkscreen; if so then refer to -CPG (or similar) drawing
for location and/or the pick and place file (as found in the gerber files)
If a line item has multiple part numbers, they are not to be interpreted as any order of preference
If a line item has multiple part numbers, and the substitution code is 10, then only use parts as listed.
Mixing is allowed (for example, if 2 manufacturers are listed, and qty is 5, then 2 parts may be from vendor A and 3 parts from vendor B) regardless of
code.
BOM Substitution Notes:
The third column nomenclature is to be used for second sourcing components as follows:
1. Any substitution allowed, as long as mechanically identical (non-electrical items only) (visually different ok)
2. Any susbstitution allowed, as long as mechanically similar (non-electrical items only) (visually different ok)
3. Any substitution, as long as mechanically and visually identical (non-electrical items only)
4. Any substitution allowed, as long as mechanically and visually similar (non-electrical items only)
5. Any substitution allowed, as long as mechanically and visually identical and electrically similar
6. Any substitution allowed, as long as mechanically, electrically and visually similar
7. Reserved for future usage.
8. Reserved for future usage
9. Substitution not recommended, but allowed if mechanically, electrically and visually similar. Only substitute if no alternative.
10. No substitution allowed.
"Identical" is to be interpreted as "meeting the same specifications" with no deviation from the specifications.
If no manufacturer is given, then do not deviate from stated specifications in the Description field.
If a manufacturer is given, do not deviate from the specifications from the manufacturer--the Description field is for reference only then.
"Similar" is to be interpreted as "meeting or exceeding the stated specifications, in regards to electrical and/or mechanical
parameters (see Substitution code).

If no manufacturer is given, then do not deviate from stated specifications in the Description field.
If a manufacturer is given, do not deviate from the specifications from the manufacturer--the Description field is for reference only then.
"Similar" as applied to visual means different colors may be used, unless otherwise noted. For example, an item with Substitution code 6 can
typically be any color.
However, if the description states "red" and the substitution code is 4, 6 or similar, then a red item must be used--but it may be any shade of red.
For example, if a capacitor is to be "identical", it must have the same voltage and tempco etc ratings as stated in the description.
If a capacitor is to be similar, the voltage rating may be higher, the tempco lower, etc.
Unless if the Substitution code is 10, "identical" parts may be sourced from different manufacturers and may have slight differences in appearance.
These subtle differences are ok.
Substituting for "Similar" parts:
Capacitors:
-tempco must be same or go down. Alternately, go up in this order: Z5U, X5R, X7R, NP0, C0G
-tolerance must be same or go down
-voltage rating must be same or go up
-unless otherwise stated, capacitance value must be identical
-unless otherwise stated, lead spacing must be same; external dimensions must be the same or smaller
Resistors:
-tempco must same or go down
-tolerance must be same or go down
-unless otherwise stated, resistance value must be identical
Note: when going from 5% to 1%, use nearest value size
-power dissapation must be same or greater
-unless otherwise stated, package size must be the same
-unless otherwise stated, coloring and marking can vary
Diodes and Transistors:
-unless otherwise stated, package size must be the same
IC's, Connectors, and all other parts::
-unless otherwise stated, package size must be the same (DIP16, SOIC-8, etc)
Manufacturer Part Number Discrepencies
Every attempt will be made to provide a workable part number. However, prefixes and suffixes can vary over time.
If second sourcing from a different manufacturer, make sure that the requirements as noted under the Description column are met.
In general, if temperature option(s) are not noted, parts specified to work from 0-85C will be sufficent.
If package information is not given, please check the manufacturer datasheet for package type.
Any and all descrepencies should be reported to Allegro MicroSystems for correction and updates.
