Key Parameters

Substitute Part Grouping Explanation

Substitution of the QR/P4-40S-C(02) is determined by strict equivalence across the following critical parameters:

• Connector type: Housing for female sockets
• Number of positions: 40
• Pitch specification: 0.100" (2.54mm)
• Number of rows: 2
• Mounting configuration: Panel mount
• Connector style: Rack and panel
• Color: Black
• Mating guide feature presence
• RoHS compliance status
• MSL rating: 1 (Unlimited)

The QR/P4-40S-C(22) meets all these criteria and is identified as a direct substitute. The primary distinction between these parts is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The QR/P4-40S-C(22) is the qualified substitute for the obsolete QR/P4-40S-C(02). Both components are manufactured by Hirose Electric Co Ltd and maintain identical electrical and mechanical specifications across all critical parameters. The QR/P4-40S-C(22) carries active product status, ensuring continued availability and supply chain support. Both parts maintain RoHS compliance and equivalent MSL ratings, satisfying regulatory and environmental requirements. The QR/P4-40S-C(22) is supplied in bulk packaging, which may require adjustment to procurement and inventory management procedures compared to the original part specification.

Frequently Asked Questions (FAQ)

Q: Can the QR/P4-40S-C(22) be used as a direct replacement for the QR/P4-40S-C(02)?

A: Yes. Both connectors share identical electrical and mechanical specifications, including 40 positions, 0.100" pitch, 2-row configuration, panel mount design, and mating guide feature. The substitute maintains equivalent RoHS compliance and MSL rating.

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

A: The primary differences are product status and packaging. The QR/P4-40S-C(02) is obsolete, while the QR/P4-40S-C(22) is active. The QR/P4-40S-C(22) is supplied in bulk packaging rather than the unspecified packaging of the original part.

Q: Are there any compatibility concerns when switching to the QR/P4-40S-C(22)?

A: No compatibility concerns exist. The connectors are mechanically and electrically equivalent. Bulk packaging may affect handling and storage procedures but does not impact functional performance.

Q: Do both parts require the same contact specifications?

A: Both housings are specified as contacts not included. Contact selection and compatibility remain independent of the housing choice and must be determined based on application requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the QR/P4-40S-C(02) and QR/P4-40S-C(22) are RoHS compliant with MSL rating 1 (Unlimited).
