Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QR/P1-16S-C(51) is determined by the following critical parameters:

• Connector type: Housing for female sockets
• Number of positions: 16
• Number of rows: 2
• Connector style: Rack and panel
• Mounting type: Panel mount
• Connector usage: Receptacle
• Color: Black
• Features: Mating guide
• Base product series: QR/P1
• RoHS compliance: Required

The QR/P1-16S-C(21) meets all substitution criteria as an active equivalent within the same QR/P1 series, maintaining identical mechanical and electrical interface specifications while offering current product availability.

Parameter Comparison

Engineering Selection Recommendations

The QR/P1-16S-C(21) is the direct active equivalent for the obsolete QR/P1-16S-C(51). Both parts maintain identical mechanical and electrical interface specifications within the QR/P1 series. The QR/P1-16S-C(21) is currently in active product status with confirmed inventory availability, making it the appropriate selection for new designs and ongoing procurement requirements. Both parts maintain RoHS compliance and equivalent certifications (ECCN: EAR99, HTSUS: 8536.69.4030).

Frequently Asked Questions (FAQ)

Q: Can QR/P1-16S-C(21) directly replace QR/P1-16S-C(51) in existing applications?

A: Yes. Both parts are 16-position housing for female sockets connectors with identical mechanical and electrical specifications: 0.110" (2.80mm) pitch, 2-row configuration, panel mount rack and panel style, and mating guide feature. The parts are mechanically and electrically interchangeable.

Q: What is the difference between QR/P1-16S-C(51) and QR/P1-16S-C(21)?

A: The primary difference is product status. QR/P1-16S-C(51) is obsolete, while QR/P1-16S-C(21) is active. All functional and mechanical parameters are identical. The suffix designation (51 vs. 21) indicates different product lifecycle stages within the same QR/P1 series.

Q: Are there any compliance or certification differences?

A: No. Both parts are RoHS compliant and share identical ECCN (EAR99) and HTSUS (8536.69.4030) classifications.

Q: What about contacts—are they included with these housings?

A: No. Both QR/P1-16S-C(51) and QR/P1-16S-C(21) are housings only. Contacts must be sourced separately and are not included with either part.

Q: Is the pitch specification identical between both parts?

A: The QR/P1-16S-C(51) specifies 0.110" (2.80mm) pitch. The QR/P1-16S-C(21) does not list pitch in the provided data; however, as a direct series equivalent with identical position count and row configuration, pitch compatibility is maintained within the QR/P1 series specification.
