PC/104 AND PC/104 Plus CONNECTORS
1. DESCRIPTION OF COMPONENT AND INTENDED APPLICATION.
PC/104 and PC/104 Plus connectors are an industry-standard connector system used in PC/104
Embedded PC module stack applications. The PC/104 module stack is designed to use less space
and at a lower cost than an equivalent backplane system, by utilising stackthrough connectors to
interconnect PC boards within a stack. Standard height between module boards is 0.6” (15.24mm).
8-bit Module, comprising:
 J1 = 32+32-way 2.54mm pitch
Stackthrough connector
16-bit Module, comprising:
 J1 = 32+32-way 2.54mm pitch
Stackthrough connector
 J2 = 20+20-way 2.54mm pitch

Figure 1 – PC/104 Stack
PC/104 connectors are 2.54mm pitch, either 32+32 or 20+20 ways. PC/104 Plus connectors are
2.00mm pitch, 4 x 30 (120) ways. The sockets have a tuning-fork style of contact. Solder or pressfit tail options are available, as are accessories for the range (see Appendix 1).
2. MARKING OF COMPONENT AND/OR PACKAGE (ORDER CODE).
