Frequently Asked Questions (FAQ)

Q: Can QR/P1-32P-C(21) be used as a direct replacement for QR/P1-32P-C(51)?

A: Yes. Both connectors share identical mechanical and electrical specifications: 32 positions, 2 rows, 0.177" (4.50mm) pitch, rack and panel style, panel mount configuration, and guide pin features. They are functionally equivalent.

Q: What is the primary reason to substitute QR/P1-32P-C(51)?

A: QR/P1-32P-C(51) is obsolete. QR/P1-32P-C(21) is the active equivalent from the same QR/P1 series and is currently manufactured and stocked.

Q: Are there packaging differences between these parts?

A: QR/P1-32P-C(51) packaging is not specified. QR/P1-32P-C(21) is supplied in bag packaging.

Q: Do both parts meet RoHS requirements?

A: QR/P1-32P-C(51) is explicitly RoHS Compliant. RoHS compliance status for QR/P1-32P-C(21) is not documented in the provided specifications.

Q: What is the pitch specification for these connectors?

A: QR/P1-32P-C(51) has a pitch of 0.177" (4.50mm). Pitch specification for QR/P1-32P-C(21) is not provided in available data.

Q: Are contacts included with these housings?

A: No. Both QR/P1-32P-C(51) and QR/P1-32P-C(21) are housings for male pins only. Contacts are not included and must be sourced separately.
