REQUIREMENTS:
Dimensions and configurations: See figures 1 thru 4. Interface dimensions shall conform to
MIL-DTL-38999, except as noted.
This connector mates with MIL-DTL-38999/26, MIL-DTL-38999/29, MIL-DTL-38999/30, and
MIL-DTL-38999/31.
Air leakage: Testing shall be in accordance with EIA-364-02, except the minimum period of
measurement shall be 10 seconds. The air leakage rate shall be no greater than 1 atmospheric cubic
-3
3
inch per hour (4.55 X 10 cm /s) Stowage receptacles shall be mated to connectors having either
contacts or inserts removed so that a pressure of 10 lbft/in2 (.703 Kg/cm2 ) can be applied against the
insides of the stowage receptacles.
Qualification (all classes). Qualification shall be in accordance with MIL-DTL-38999, conducted on
two samples of each shell size, except only the following sequence of tests shall be required:
Examination of product
Coupling torque
Dynamic salt spray (corrosion)
Air leakage (see requirement)
Visual and mechanical
Qualification (classes J and M only): Qualification shall be in accordance with MIL-DTL-38999,
except that in addition to the test sequence specified for all classes above, the following tests shall be
required:
Temperature cycling
Hydrolytic stability
Group A sampling inspection. Sampling for group A inspection shall be as specified in table I.

* NOTE: For shell size 9 only:
Shell size code A is for use with plugs with mating key polarizations “C”, “E” or “N”.
Shell size code AA is for use with plugs with mating key polarizations “A”, “B” or “D”.
Class F is not for Navy use. Class F is inactive for use in Air Force new design.
NOTE: The term PIN is equivalent to the term (part number, identification number, and type
designator) which was previously used in this specification.
Change effectivity. Unless otherwise specified by the preparing activity and/or the qualifying activity, all
changes from the previous revision of this specification sheet shall become effective within 90 days of the
date of publication of the latest revision. If unable to implement changes within the 90 day time period,
the manufacturer or value added distributor shall notify the qualifying activity. The qualifying activity shall
determine if an extension may be granted.
Disposition of stock. Unless otherwise specified by the qualifying activity and coordinated with the
preparing activity, qualified manufacturers and their selling agents or distributors may continue to
ship stowage receptacles which were manufactured in accordance with the previous revision of this
specification sheet for a period of 18 months from the date of the latest revision, provided that form, fit
and function are not affected.
Changes from previous issue. The margins of this specification are marked with vertical lines 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.
