Acquisition documents must specify the following: a. Title, number, date of the specification, and complete PIN. * b. If not ot

30、herwise specified (see 2.1), the versions of the individual documents referenced will be those in effect on the date of release of the solicitation. c. Packaging requirements (see 5.1). * 6.3 MIL-PRF-27208 substitution data. Resistors of MIL-PRF-39015/2 regardless of their failure rate designation a

31、re substitutes for resistors of the same resistance value, tolerance, terminal characteristic, and resistance temperature specified in the specification MIL-PRF-27208/4. * 6.4 Tin whisker growth. The use of alloys with tin content greater than 97 percent, by mass, may exhibit tin whisker growth prob

32、lems 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

33、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). * 6.5 Caution note. The QPL manufacturer of the “L” termination of this slash sheet has always us

34、ed 100 percent tin plating on their internal tabs. Termination “L” is inactive for new design, and designers are cautioned on using the “L” termination for replacement purposes (see 6.4). * 6.6 Changes from previous issue. The margins of this specification are marked with asterisks to indicate where

35、 changes from the previous issue were made. This was done as a convenience only and the Government assumes no liability whatsoever for any inaccuracies in these notations. Bidders and contractors are cautioned to evaluate the requirements of this document based on the entire content irrespective of

36、the marginal notations and relationship to the last previous issue.
