DEFENSE ELECTRONIC SUPPLY CENTER DAYTON, OHIO SIZE CODE IDENT NO. DWG NO. A 14933 87053 REV D PAGE 4 3.6 Manufacturer eligibility. To be eligible for listing as a approved source of supply, a manufacturer shall be listed on the MIL-PRF-83401 Qualified Products List for at least one part, or perform the group A and group B inspections specified herein on a sample of parts agreed upon by the manufacturer and DLA Land and Maritime - VAT. 3.6.1 Certificate of compliance. A certificate of compliance shall be required from manufacturers requesting to be a approved source of supply. 3.7 Pure tin. The use of pure tin, as an underplate or final finish, is prohibited both internally and externally. Tin content of resistor components and solder shall not exceed 97 percent, by mass. Tin shall be alloyed with a minimum of 3 percent lead, by mass (see 6.3). 3.8 Workmanship. Resistors shall be uniform in quality and free from defects that will affect life, serviceability, or appearance. 4. VERIFICATION 4.1 Qualification inspection. Qualification inspection is not applicable to this document. 4.2 Conformance inspection. 4.2.1 Inspection of product for delivery. Inspection of product for delivery shall consist of group A and group B inspection of MIL-PRF-83401. 4.2.2 Certification. The acquiring activity, at its discretion, may accept a certificate of compliance with group B requirements in lieu of performing group B tests (see 6.2c). 4.3 Visual and mechanical examination. Resistors shall be examined to verify that the materials, design, construction, physical dimensions, marking, and workmanship are in accordance with the applicable requirements of MIL-PRF-83401. 5. PACKAGING 5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When packaging of materiel is to be performed by DoD or in-house contractor personnel, these personnel need to contact the responsible packaging activity to ascertain packaging requirements. Packaging requirements are maintained by the Inventory Control Point’s packaging activity within the Military Service or Defense Agency, or within the military services system commands. Packaging data retrieval is available from the managing Military Department’s or Defense Agency’s automated packaging files, CD-ROM products, or by contacting the responsible packaging activity. 6. NOTES (This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.) 6.1 Intended use. Resistor networks described herein are intended for use in circuits where microcircuitry is intended. 6.2 Ordering data. The contract or purchase order should specify the following: a. Complete PIN (see 1.2). b. Requirements for delivery: One copy of the conformance inspection data or certification of compliance that parts have passed conformance inspection with each shipment of parts by the manufacturer. c. Whether the manufacturer performs the group B tests or provides certification of compliance with group B requirements. d. Requirements for packaging and packing. DEFENSE ELECTRONIC SUPPLY CENTER DAYTON, OHIO SIZE CODE IDENT NO. DWG NO. A 14933 87053 REV D PAGE 5 6.3 Tin whisker growth. The use of alloys with tin content greater than 97 percent, by mass, may exhibit tin whisker growth problems after manufacture. Tin whiskers may occur anytime from a day to years after manufacture and can develop under typical operating conditions, on products that use such materials. Conformal coatings applied over top of a whisker-prone surface will not prevent the formation of tin whiskers. Alloys of 3 percent lead, by mass, have shown to inhibit the growth of tin whiskers. For additional information on this matter, refer to ASTM-B545 (Standard Specification for Electrodeposited Coatings of Tin). 6.4 User of record.
