Key Parameters

Substitute Part Grouping Explanation

The QR/P4-32P-C(21) qualifies as a direct substitute for the QR/P4-32P-C(01) based on the following critical parameters that determine functional interchangeability:

• Number of Positions: 32 (identical)
• Pitch: 0.100" (2.54mm) (identical)
• Number of Rows: 2 (identical)
• Connector Type: Housing for Male Pins (identical)
• Connector Style: Rack and Panel (identical)
• Mounting Type: Panel Mount (identical)
• Connector Usage: Plug (identical)
• Features: Guide Pin (identical)
• Color: Black (identical)
• RoHS Status: RoHS Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

The primary distinction between these parts is product status: QR/P4-32P-C(01) is obsolete, while QR/P4-32P-C(21) is active. Both parts share identical electrical and mechanical specifications, confirming direct substitution capability.

Parameter Comparison

Engineering Selection Recommendations

The QR/P4-32P-C(21) is the recommended substitute for the obsolete QR/P4-32P-C(01). Both parts maintain identical electrical and mechanical specifications across all critical parameters, ensuring direct functional compatibility in rack and panel backplane applications.

The QR/P4-32P-C(21) carries active product status from Hirose Electric Co Ltd, providing access to current manufacturing, quality assurance, and supply chain support. Both parts are RoHS compliant and carry identical moisture sensitivity ratings, confirming compliance consistency for regulated applications.

For new designs or system replacements, the QR/P4-32P-C(21) should be specified. For legacy system maintenance where the original QR/P4-32P-C(01) remains available in inventory, either part may be used interchangeably without design modification.

Frequently Asked Questions (FAQ)

Q: Can QR/P4-32P-C(21) be used as a direct replacement for QR/P4-32P-C(01)?

A: Yes. Both parts are identical in connector type, position count (32), pitch (0.100"/2.54mm), row configuration (2), mounting style (panel mount), and all electrical and mechanical specifications. Direct substitution is supported without modification.

Q: What is the difference between QR/P4-32P-C(01) and QR/P4-32P-C(21)?
