Mil-Spec Mate-To Check
Do these two connectors mate? Paste a part number into each column, or copy two columns from a spreadsheet and paste them in at once. Each row is checked with the same mating rules the part number builders use for their mate lists.

Upgrade accountWhat counts as a mate
Two connectors mate when they are in the same series and one is a plug and the other a receptacle, with the same shell size, insert arrangement and polarization (or insert position), and opposite contact gender, pin on one side and socket on the other. A pair that passes is checked against the builder's mate list for the first connector, so the answer is the same as picking the first connector in its builder and looking for the second one in its list of mates.
A pair can mate and still carry a note: a different class (shell finish), different contact plating or a different contact durability rating. The builders' "similar plating" and "similar contacts" options screen for these, and this page lists them beside the result instead of failing the pair.
A part number that is not in any builder's data is reported as not recognized, never guessed. Paste a part number, or a column of them, into the builders to see how it breaks down. The result is a design aid: verify a pair against the current specification sheets before you release a drawing or an order.
