Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QR/P4-12S-C(01) is determined by strict equivalence across the following critical parameters:

• Connector Type: Housing for Female Sockets
• Number of Positions: 12
• Pitch: 0.100" (2.54mm)
• Number of Rows: 2
• Mounting Type: Panel Mount
• Connector Style: Rack and Panel
• Color: Black
• Features: Mating Guide
• RoHS Compliance: Required
• MSL Rating: 1 (Unlimited)

The QR/P4-12S-C(21) meets all substitution criteria. The primary distinction is product status: QR/P4-12S-C(01) is obsolete, while QR/P4-12S-C(21) is active. The packaging difference (unspecified for QR/P4-12S-C(01) versus Bag for QR/P4-12S-C(21)) does not affect functional or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The QR/P4-12S-C(21) is the direct functional equivalent of the QR/P4-12S-C(01). Both components are manufactured by Hirose Electric Co Ltd and maintain identical electrical and mechanical specifications across all critical parameters. The QR/P4-12S-C(21) carries active product status and maintains full RoHS compliance with MSL 1 rating, making it suitable for new designs and ongoing system support where the QR/P4-12S-C(01) is no longer available.

For applications currently using QR/P4-12S-C(01), direct substitution with QR/P4-12S-C(21) is supported without design modification. Inventory availability of QR/P4-12S-C(21) (983 Pcs) provides adequate supply for procurement planning.

Frequently Asked Questions (FAQ)

Q: Can QR/P4-12S-C(21) be used as a direct replacement for QR/P4-12S-C(01)?

A: Yes. Both components share identical connector type, position count, pitch, row configuration, mounting method, and color. All electrical and mechanical parameters are equivalent.

Q: What is the difference between QR/P4-12S-C(01) and QR/P4-12S-C(21)?

A: The primary difference is product status. QR/P4-12S-C(01) is obsolete, while QR/P4-12S-C(21) is active. Packaging differs (unspecified versus Bag), but this does not affect functional compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both QR/P4-12S-C(01) and QR/P4-12S-C(21) are RoHS compliant with MSL 1 (Unlimited) rating.

Q: Does the packaging difference affect compatibility?

A: No. Packaging is a logistics consideration only and does not impact electrical or mechanical performance.

Q: Why is QR/P4-12S-C(01) listed as obsolete?

A: Obsolescence indicates the part is no longer in active production. QR/P4-12S-C(21) is the active equivalent and should be used for new procurement and system support.
