Key Parameters

Substitute Part Grouping Explanation

Substitution of the QR/P4-40P-C(01) is determined by strict equivalence across the following critical parameters:

• Connector Type: Housing for Male Pins (mechanical interface requirement)
• Number of Positions: 40 (pin count compatibility)
• Pitch: 0.100" (2.54mm) (spacing and alignment requirement)
• Number of Rows: 2 (physical layout requirement)
• Connector Style: Rack and Panel (application requirement)
• Mounting Type: Panel Mount (installation requirement)
• Connector Usage: Plug (functional role requirement)
• Features: Guide Pin (mechanical alignment requirement)
• Color: Black (specification requirement)

The substitute part QR/P4-40P-C(21) maintains identical values across all these parameters, establishing direct functional and mechanical equivalence.

Parameter Comparison

Engineering Selection Recommendations

The QR/P4-40P-C(21) is the direct substitute for the QR/P4-40P-C(01). Both parts are manufactured by Hirose Electric Co Ltd and maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the QR/P4-40P-C(01) is obsolete while the QR/P4-40P-C(21) is active. Both parts maintain RoHS compliance and equivalent moisture sensitivity ratings. For new designs and ongoing system support, the QR/P4-40P-C(21) is the appropriate selection due to its active product status and continued availability.

Frequently Asked Questions (FAQ)

Q: Can QR/P4-40P-C(21) directly replace QR/P4-40P-C(01) in existing applications?

A: Yes. Both connectors are identical in connector type, position count, pitch, row configuration, mounting style, and mechanical features. Direct substitution is supported without modification to mating interfaces or mounting hardware.

Q: What is the difference between QR/P4-40P-C(01) and QR/P4-40P-C(21)?

A: The parts are functionally and mechanically equivalent. The primary difference is product lifecycle status: QR/P4-40P-C(01) is obsolete, while QR/P4-40P-C(21) is active. The suffix designation (01 versus 21) indicates packaging or manufacturing revision, but electrical and mechanical specifications remain identical.

Q: Are both parts RoHS compliant?

A: Yes. Both QR/P4-40P-C(01) and QR/P4-40P-C(21) are RoHS compliant with identical moisture sensitivity levels (MSL 1 - Unlimited).

Q: What packaging is available for each part?

A: QR/P4-40P-C(01) is supplied with standard packaging. QR/P4-40P-C(21) is supplied in bulk packaging. Both are available in new original condition.

Q: Are contacts included with these connectors?

A: No. Both the QR/P4-40P-C(01) and QR/P4-40P-C(21) are housing assemblies supplied without contacts. Contacts must be sourced separately and installed according to Hirose specifications.
