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:

6.4 Power rating (free air). The free air (resistor not mounted on a chassis) power rating is as listed in 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.
