6. NOTES
6.1 Intended use. In addition tot he notes specified herein, the notes specified in MIL-PRF-18546 are
applicable to this specification.
6.2 Acquisition requirements. Acquisition documents must specify the following:
a. Title, number, and date of this specification and the complete PIN (see 1.2.1).
b. Issue of DoDISS to cited in the solicitation, and if required, the specific issue of individual
documents referenced (see 2.1).
c. Packaging requirements (see 5.1).
6.3 Substitution data. The resistors specified herein are not for use in design after date of this
specification. These resistors are suitable for use in design contracts effective prior to 22 April 1970, and
for logistic support of existing military equipment. Resistors specified in MIL-PRF-39009 are preferred for
design and regardless of failure rate designation are authorized as substitutes for the inactivated resistor
of the same resistance and tolerance of this specification. Substitution for characteristic G and N are as
follows:

table II.
6.5 Chassis area derating curves. Figure 2 may be used for design information.
6.6 Interchangeability. Items in this specification are mutually interchangeable with items of the same
style and characteristic procured under MIL-R-18546/1E.
6.7 Changes from previous issue. Marginal notations are not used in this revision to identify changes
with respect to the previous issue due to the extensiveness of the changes.
