MIL-PRF-39015/2J
6.2 Acquisition requirements. Acquisition documents must specify the following:
a. Title, number, date of the specification, and complete PIN.
*
b. If not otherwise specified (see 2.1), the versions of the individual documents referenced will be
those in effect on the date of release of the solicitation.
Packaging requirements (see 5.1).
c.
6.3 MIL-PRF-27208 substitution data. Resistors of MIL-PRF-39015/2 regardless of their failure rate
*
designation are 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 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).
6.5 Caution note. The QPL manufacturer of the "L" termination of this slash sheet has always used
*
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 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 the marginal notations and relationship to the last previous issue.
