6.3 Qualification. With respect to products requiring qualification, awards will be made only for products which are, at the time of

award of contract, qualified for inclusion in Qualified Products List QPL No.19500 whether or not such products have actually been so

listed by that date. The attention of the contractors is called to these requirements, and manufacturers are urged to arrange to have the

products that they propose to offer to the Federal Government tested for qualification in order that they may be eligible to be awarded

contracts or purchase orders for the products covered by this specification. Information pertaining to qualification of products may be

obtained from Defense Supply Center Columbus, ATTN: DSCC-VQE, 3990 East Broad Street, Columbus, OH 43216-5000.

6.4 Suppliers of JANC die. The qualified JANCH and JANCK suppliers with the applicable letter version will be identified on the QPL

(e.g. JANCKA1N6683).

6.5 Substitution information. The 1N6683 (MIL-PRF-19500/625) is the preferred type in lieu of the 1N4938 and 1N4938-1 (MIL-PRF-

19500/169) for high reliability, high stress application (see 1.1). The 1N6683 should be used whenever available.

6.5.1 Cross reference substitution list. JANS level will no longer be built to MIL-PRF-19500/169. Devices in stock are acceptable

provided the date code does not exceed the date of implementation of MIL-PRF-19500/169. Devices required for spec flight applications

are found herein. A PIN for PIN replacement table follows, and these devices are directly interchangeable.
