Substitute Part Grouping Explanation

Substitution of the QR/P4-24S-C(01) is determined by strict equivalence across the following critical parameters:

• Connector Type: Housing for Female Sockets (must match exactly)
• Number of Positions: 24 (must match exactly)
• Pitch: 0.100" (2.54mm) (must match exactly)
• Number of Rows: 2 (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 match exactly)

The QR/P4-24S-C(21) satisfies all critical substitution criteria. Variations in color (black to blue) and product status (obsolete to active) do not affect electrical or mechanical compatibility. Both parts share identical contact pitch, position count, row configuration, and mounting methodology.

Engineering Selection Recommendations

The QR/P4-24S-C(21) is a direct functional equivalent to the QR/P4-24S-C(01). Selection between these parts should be based on the following factors:

Product Status: The QR/P4-24S-C(01) is classified as obsolete. The QR/P4-24S-C(21) maintains active product status with Hirose Electric Co., Ltd., ensuring continued availability and manufacturer support.

Compliance: Both parts maintain RoHS compliance. The QR/P4-24S-C(21) carries ROHS3 certification, representing current regulatory alignment. Both parts are classified as ECCN EAR99 and share identical HTSUS coding (8536.69.4030).

Moisture Sensitivity: Both parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Color Differentiation: The housing color change from black to blue does not affect electrical or mechanical performance. Color selection should be based on system documentation, panel aesthetics, or internal color-coding standards.

Frequently Asked Questions (FAQ)

Q: Can QR/P4-24S-C(21) be used as a direct replacement for QR/P4-24S-C(01)?

A: Yes. Both parts share identical electrical and mechanical specifications across all critical parameters: 24-position housing, 0.100" pitch, 2-row configuration, rack and panel style, panel mount type, and mating guide feature. The parts are functionally interchangeable.

Q: What is the difference between these two part numbers?

A: The primary differences are housing color (black versus blue) and product status (obsolete versus active). These differences do not affect connector performance, compatibility, or electrical characteristics.

Q: Are there any compliance or certification differences?

A: Both parts are RoHS compliant. The QR/P4-24S-C(21) carries ROHS3 certification, which represents the current regulatory standard. Both parts share identical ECCN and HTSUS classifications.

Q: Does the color change affect mating compatibility?

A: No. Housing color is a cosmetic attribute and does not affect mechanical fit, electrical performance, or mating characteristics with compatible plug connectors.

Q: What is the MSL rating for these connectors?

A: Both parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity constraints. These connectors can be stored and handled without special moisture control measures.

Q: Are contacts included with these housings?

A: No. Both the QR/P4-24S-C(01) and QR/P4-24S-C(21) are housings only. Contacts must be sourced separately and inserted into the housing according to Hirose specifications.

Q: What is the pitch specification?

A: Both parts feature 0.100" (2.54mm) pitch, which defines the center-to-center spacing between contact positions. This specification is critical for mating compatibility and must match the corresponding plug connector.
