Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QR/P4-16P-C(01) is determined by the following critical parameters:

• Manufacturer: Hirose Electric Co Ltd (same manufacturer ensures design compatibility)
• Series: QR/P4 (maintains mechanical and electrical interface standards)
• Connector Type: Housing for Male Pins (functional interface requirement)
• Number of Positions: 16 (electrical contact count)
• Pitch: 0.100" (2.54mm) (mechanical spacing standard)
• Number of Rows: 2 (physical layout configuration)
• Connector Style: Rack and Panel (application category)
• Mounting Type: Panel Mount (installation method)
• Connector Usage: Plug (functional role)
• Features: Guide Pin (alignment mechanism)

The QR/P4-16P-C(21) qualifies as a direct substitute based on matching all critical parameters. Variations in color (black to blue) and product status (obsolete to active) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The QR/P4-16P-C(21) is a direct functional equivalent to the QR/P4-16P-C(01). Selection between these parts should be based on the following factors:

Product Status: The QR/P4-16P-C(01) is classified as obsolete. The QR/P4-16P-C(21) maintains active product status with Hirose Electric Co Ltd, ensuring ongoing availability and manufacturer support.

Compliance: Both parts meet RoHS requirements. The QR/P4-16P-C(21) carries ROHS3 compliance certification, representing current regulatory standards. The QR/P4-16P-C(01) meets RoHS compliance. Both parts are REACH unaffected and share identical ECCN and HTSUS classifications.

Mechanical and Electrical Compatibility: All critical parameters match between the two parts. The housing accommodates 16 male pins in a 2-row configuration with 0.100" pitch spacing. Both parts include guide pin features for proper alignment in rack and panel installations.

Color Variation: The QR/P4-16P-C(21) features blue housing compared to the black housing of the QR/P4-16P-C(01). This is a cosmetic difference that does not affect electrical or mechanical function.

Frequently Asked Questions (FAQ)

Q: Can the QR/P4-16P-C(21) directly replace the QR/P4-16P-C(01) in existing assemblies?

A: Yes. Both parts share identical electrical and mechanical specifications, including connector type, position count, pitch, row configuration, mounting method, and guide pin features. The housing color difference does not affect functional compatibility.

Q: What is the significance of the product status difference between these parts?

A: The QR/P4-16P-C(01) is obsolete, indicating Hirose Electric Co Ltd no longer manufactures or supports this part. The QR/P4-16P-C(21) maintains active status, ensuring continued availability, technical support, and compliance with current manufacturing standards.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS compliant and REACH unaffected. The QR/P4-16P-C(21) carries ROHS3 certification, representing the current regulatory standard. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4030) classifications.

Q: Does the color difference affect connector performance?

A: No. Color is a cosmetic attribute that does not influence electrical performance, mechanical fit, or interface compatibility. Selection between black and blue housing should be based on system identification or documentation requirements only.

Q: What packaging options are available?

A: The QR/P4-16P-C(01) is available in standard packaging. The QR/P4-16P-C(21) is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: Are contacts included with these housings?

A: No. Both the QR/P4-16P-C(01) and QR/P4-16P-C(21) are housings only. Male pin contacts must be sourced separately and are not included with the housing.
