[MRCA] [MMRCG] need help with connector compatibility

[Nick England]

Both are MIL-DTL-26482 connectors
MS 3116 is series 1 and MS 3476 is series 2
The full spec is here -
"
https://landandmaritimeapps.dla.mil/Downloads/MilSpec/Docs/MIL-DTL-26482/dtl26482.pdf
"

The important part is "The two series of connectors are intermateable when
using power contacts and are not intermateable when using shielded
contacts. When intermated, the minimum performance requirement for series 1
type connectors will be met."

a. Series 1 – Connector, bayonet coupling, solder or front release crimp
removable contacts (125ºC). Series 1, hermetic are also available.
Alternative conductive finishes, including W, T and K, are available (See
3.3.9.4) (See 6.1 for intended use.).
b. Series 2 – Connector, bayonet coupling, rear release crimp removable
contacts (classes A and L (200ºC) and classes H, N, T, W and K (175°C)).
Series 2, hermetic connectors are available with nonremovable solder type
contacts or crimp removable terminations (see 6.2).

have fun

I’ve done this stuff in the past and its not very fun. So I am relegated to
watching on ebay for cables that have the right connectors on them already
(and hope all conductors are present and 1:1 in configuration).

the L family are silver or nickel plated and the J family are green.

the body parts. Also beware Glenair connectors use a different size for the
back shell and extenders so the number will look correct but they are way
different.
