QR/P4-40S-C(01) Equivalent & Substitute Parts

Part Overview

The QR/P4-40S-C(01) is a 40-position housing for female sockets backplane connector manufactured by Hirose Electric Co Ltd. This rack and panel receptacle connector features a black housing with mating guide and panel mount configuration. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and component sourcing. Substitute parts must maintain electrical and mechanical compatibility across connector pitch, position count, mounting type, and physical dimensions.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the QR/P4-40S-C(01) is determined by the following critical parameters:

• Number of Positions: 40 (must match exactly)
• Pitch: 0.100" (2.54mm) (must match exactly)
• Number of Rows: 2 (must match exactly)
• Connector Type: Housing for Female Sockets (must match exactly)
• Connector Style: Rack and Panel (must match exactly)
• Mounting Type: Panel Mount (must match exactly)
• Connector Usage: Receptacle (must match exactly)
• Features: Mating Guide (must be present)

The QR/P4-40S-C(21) qualifies as a direct substitute because it maintains identical electrical and mechanical specifications across all critical parameters. Variations in color (black to blue) and product status (obsolete to active) do not affect functional compatibility in backplane connector applications.

Parameter Comparison

Engineering Selection Recommendations

The QR/P4-40S-C(21) is the direct substitute for the obsolete QR/P4-40S-C(01). Selection is based on the following factors:

Product Status: The QR/P4-40S-C(21) carries active product status, ensuring continued availability and manufacturing support. The QR/P4-40S-C(01) is obsolete and subject to supply discontinuation.

Compliance: Both parts maintain RoHS compliance. The QR/P4-40S-C(21) meets ROHS3 requirements, representing current regulatory standards. Both parts are REACH unaffected and carry identical ECCN and HTSUS classifications.

Electrical and Mechanical Compatibility: All critical connector specifications are identical, including 40-position configuration, 0.100" pitch, 2-row layout, panel mount receptacle design, and mating guide feature. These parameters ensure direct functional interchangeability in backplane connector applications.

Non-Critical Differences: Color variation (black to blue) and packaging format (bulk) do not affect electrical performance or mechanical fit. These are cosmetic and logistical considerations only.

Frequently Asked Questions (FAQ)

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

A: Yes. Both connectors share identical electrical and mechanical specifications across all critical parameters: 40 positions, 0.100" pitch, 2-row configuration, panel mount receptacle design, and mating guide feature. Direct substitution is supported.

Q: Does the color difference (black vs. blue) affect compatibility?

A: No. Color is a cosmetic attribute and does not impact electrical performance, mechanical fit, or functional operation in backplane connector applications.

Q: What is the significance of the product status change from obsolete to active?

A: Active product status indicates QR/P4-40S-C(21) is in current production with guaranteed availability and manufacturing support. The obsolete status of QR/P4-40S-C(01) means supply is limited and subject to discontinuation. Transition to the active substitute ensures long-term component sourcing reliability.

Q: Are there packaging differences between these parts?

A: QR/P4-40S-C(01) packaging is not specified in available data. QR/P4-40S-C(21) is supplied in bulk packaging. Packaging format does not affect connector performance or compatibility.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both parts are RoHS compliant. QR/P4-40S-C(21) meets ROHS3 standards, representing current regulatory requirements. Both carry identical ECCN (EAR99) and HTSUS (8536.69.4030) classifications.

Q: What parameters must match for a valid substitute in the QR/P4 series?

A: Valid substitutes must maintain identical specifications for: number of positions (40), pitch (0.100"), number of rows (2), connector type (housing for female sockets), connector style (rack and panel), mounting type (panel mount), connector usage (receptacle), and features (mating guide).
