QR/P4-32S-C(01) Equivalent & Substitute Parts

Part Overview

The QR/P4-32S-C(01) is a 32-position housing for female sockets connector manufactured by Hirose Electric Co Ltd, designed for rack and panel backplane applications. This connector features a black panel mount configuration with a 0.100" (2.54mm) pitch and integrated mating guide. The part is currently classified as obsolete, making identification of active equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

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

• 32-position connector housing configuration
• 0.100" (2.54mm) pitch spacing
• 2-row arrangement
• Panel mount rack and panel style
• Female socket housing type
• Black color specification
• Integrated mating guide feature
• RoHS compliance and MSL 1 rating

The primary distinction between the main part and substitute is product status: QR/P4-32S-C(01) is obsolete, while QR/P4-32S-C(21) is active. The packaging differs (unspecified for the main part versus bulk for the substitute), but this does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using QR/P4-32S-C(01), the QR/P4-32S-C(21) is the appropriate active equivalent. Both parts maintain identical electrical and mechanical specifications, including connector configuration, pitch, mounting arrangement, and compliance certifications. The transition from obsolete to active status makes QR/P4-32S-C(21) the recommended selection for new designs and ongoing procurement. Both parts carry RoHS compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage environments.

Frequently Asked Questions (FAQ)

Q: Can QR/P4-32S-C(21) directly replace QR/P4-32S-C(01) in existing applications?

A: Yes. Both parts share identical electrical and mechanical parameters, including 32-position configuration, 0.100" pitch, 2-row arrangement, panel mount style, and mating guide feature. The parts are mechanically and functionally interchangeable.

Q: What is the significance of the different product status classifications?

A: QR/P4-32S-C(01) is classified as obsolete, indicating it is no longer manufactured or supported by Hirose Electric Co Ltd. QR/P4-32S-C(21) is active and available for procurement, making it the appropriate choice for new designs and long-term supply chain planning.

Q: Does packaging affect the substitution decision?

A: Packaging (bulk versus other formats) does not affect electrical or mechanical compatibility. The packaging specification relates only to order quantity and handling, not to connector performance or fit.

Q: Are there compliance differences between the two parts?

A: No. Both parts are RoHS compliant and carry MSL 1 (Unlimited) rating, meeting identical environmental and regulatory requirements.

Q: What parameters must remain constant for substitution validity?

A: The following parameters must match for direct substitution: number of positions (32), pitch (0.100"), number of rows (2), mounting type (panel mount), connector style (rack and panel), connector type (housing for female sockets), and color (black).
