Frequently Asked Questions (FAQ)

Q: Can the QR/P1-12S-C(21) directly replace the QR/P1-12S-C(51) in existing designs?

A: Yes. Both components share identical specifications for connector type, position count, row configuration, mounting method, and all functional features. The QR/P1-12S-C(21) is a direct functional equivalent.

Q: What is the difference between QR/P1-12S-C(51) and QR/P1-12S-C(21)?

A: The primary differences are product status and packaging. The QR/P1-12S-C(51) is obsolete, while the QR/P1-12S-C(21) maintains active status. The QR/P1-12S-C(21) is supplied in bulk packaging.

Q: Are both parts RoHS compliant?

A: Yes. Both the QR/P1-12S-C(51) and QR/P1-12S-C(21) are RoHS compliant with identical MSL ratings of 1 (Unlimited).

Q: What does the pitch specification mean for substitution?

A: Pitch defines the center-to-center distance between connector positions. The QR/P1-12S-C(51) specifies 0.110" (2.80mm) pitch. This parameter is critical for mechanical compatibility and mating with corresponding plug connectors.

Q: Are contacts included with these housings?

A: No. Both the QR/P1-12S-C(51) and QR/P1-12S-C(21) are housings only. Contacts must be sourced separately.
