Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QR/P1-12P-C(51) is determined by strict alignment of the following critical parameters:

• Connector Type: Housing for Male Pins
• Number of Positions: 12
• Number of Rows: 2
• Connector Style: Rack and Panel
• Mounting Type: Panel Mount
• Connector Usage: Plug
• Color: Black
• Features: Guide Pin
• Base Product Series: QR/P1
• RoHS Compliance: RoHS Compliant
• MSL Rating: 1 (Unlimited)

The QR/P1-12P-C(21) qualifies as a direct substitute based on matching all critical electrical and mechanical parameters within the QR/P1 series. The primary distinction is packaging format and product status transition from obsolete to active.

Parameter Comparison

Engineering Selection Recommendations

The QR/P1-12P-C(21) is the qualified substitute for the obsolete QR/P1-12P-C(51). Both components maintain identical electrical and mechanical specifications within the QR/P1 series architecture. The QR/P1-12P-C(21) carries active product status, ensuring ongoing manufacturer support and availability. Both parts meet RoHS compliance requirements and carry MSL Level 1 rating, indicating no moisture sensitivity constraints during storage and handling. The transition from bulk to tray packaging in the substitute part reflects standard industry practice for active production components and does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Are QR/P1-12P-C(51) and QR/P1-12P-C(21) mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications: 12 positions, 2-row configuration, 0.110" (2.80mm) pitch, panel mount design, and guide pin features. They are mechanically interchangeable in rack and panel applications.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging format. The QR/P1-12P-C(51) is obsolete and supplied in bulk packaging, while the QR/P1-12P-C(21) is active and supplied in tray packaging. All electrical and mechanical parameters are identical.
