Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QR/P4-24P-C(01) is determined by the following critical parameters:

• Connector Type: Housing for Male Pins (mechanical and electrical interface requirement)
• Number of Positions: 24 (pin count compatibility)
• Pitch: 0.100" (2.54mm) (contact spacing and mating interface)
• Number of Rows: 2 (physical layout and contact arrangement)
• Mounting Type: Panel Mount (installation method)
• Connector Style: Rack and Panel (application class)
• Features: Guide Pin (alignment and mechanical stability)
• Manufacturer: Hirose Electric Co Ltd (design compatibility within product family)

The QR/P4-24P-C(21) qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary difference is housing color (black versus blue) and product status (obsolete versus active), which do not affect functional compatibility or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

The QR/P4-24P-C(21) is the qualified substitute for the obsolete QR/P4-24P-C(01). Both connectors maintain identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch, row configuration, mounting method, and guide pin features.

The QR/P4-24P-C(21) offers the additional advantage of active product status, ensuring continued manufacturer support, availability, and compliance with current regulatory standards (ROHS3 Compliant versus RoHS Compliant). Both parts maintain equivalent moisture sensitivity levels and export classifications.

The housing color difference (blue versus black) is a cosmetic distinction that does not impact electrical performance, mechanical compatibility, or functional interchangeability within rack and panel applications.

Frequently Asked Questions (FAQ)

Q: What makes QR/P4-24P-C(21) a direct substitute for QR/P4-24P-C(01)?

A: Both connectors share identical specifications for connector type, position count (24), pitch (0.100"/2.54mm), row configuration (2), mounting type (panel mount), connector style (rack and panel), and guide pin features. These parameters define the mechanical and electrical interface requirements for backplane connector applications.

Q: Does the housing color difference affect compatibility?

A: No. Housing color is a cosmetic attribute that does not influence electrical performance, mechanical fit, or functional operation. The connectors are electrically and mechanically interchangeable.

Q: Why is product status relevant for substitution?

A: The QR/P4-24P-C(01) is obsolete, meaning it is no longer manufactured or supported by Hirose Electric Co Ltd. The QR/P4-24P-C(21) maintains active status, ensuring availability, manufacturer technical support, and compliance with current regulatory requirements.

Q: Are there packaging differences between these parts?

A: The QR/P4-24P-C(01) is listed with unspecified packaging, while the QR/P4-24P-C(21) is supplied in bulk packaging. Packaging format does not affect connector functionality or compatibility.

Q: What compliance certifications apply to both parts?

A: Both connectors are classified under ECCN EAR99 and HTSUS 8536.69.4030. Both maintain MSL 1 (Unlimited) moisture sensitivity ratings. The QR/P4-24P-C(21) carries ROHS3 Compliant certification, representing current regulatory compliance standards.
