Key Parameters

Substitute Part Grouping Explanation

Substitution of the QR/P4-8P-C(01) is determined by strict equivalence across the following critical parameters:

• Connector type: Housing for male pins
• Number of positions: 8
• Pitch specification: 0.100" (2.54mm)
• Row configuration: 2 rows
• Connector style: Rack and panel
• Mounting type: Panel mount
• Connector usage: Plug
• Color: Black
• Guide pin feature presence

The QR/P4-8P-C(01) is directly substitutable with the QR/P4-8P-C(21), which maintains identical electrical and mechanical specifications across all critical parameters. The primary distinction between these parts is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The QR/P4-8P-C(21) is the direct substitute for the QR/P4-8P-C(01). Both parts are manufactured by Hirose Electric Co Ltd and maintain identical electrical and mechanical specifications. The QR/P4-8P-C(21) carries active product status, ensuring continued availability and support from the manufacturer. Both parts meet RoHS compliance requirements and carry MSL rating 1 (unlimited moisture sensitivity level).

Selection of the QR/P4-8P-C(21) is appropriate for new designs, system upgrades, and replacement applications where the obsolete QR/P4-8P-C(01) is no longer available through standard distribution channels.

Frequently Asked Questions (FAQ)

Q: Can the QR/P4-8P-C(21) directly replace the QR/P4-8P-C(01)?

A: Yes. Both parts are identical in electrical and mechanical specifications, including connector type, position count, pitch, row configuration, mounting type, and feature set. The QR/P4-8P-C(21) is the active production equivalent.

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

A: The QR/P4-8P-C(01) is obsolete, while the QR/P4-8P-C(21) is active. The QR/P4-8P-C(21) is supplied in bag packaging. All functional and dimensional specifications are identical.

Q: Are there any compatibility concerns when substituting the QR/P4-8P-C(21) for the QR/P4-8P-C(01)?

A: No compatibility concerns exist. Both parts conform to the same electrical and mechanical standards and are fully interchangeable in rack and panel applications.

Q: Do both parts require separate contact components?

A: Yes. Both the QR/P4-8P-C(01) and QR/P4-8P-C(21) are housings for male pins connectors. Contacts are not included and must be sourced separately.

Q: Are both parts RoHS compliant?

A: Yes. Both the QR/P4-8P-C(01) and QR/P4-8P-C(21) are RoHS compliant and carry MSL rating 1 (unlimited).
