Key Parameters

Substitute Part Grouping Explanation

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

• Connector Type: Housing for Female Sockets
• Number of Positions: 16
• Pitch: 0.100" (2.54mm)
• Number of Rows: 2
• Mounting Type: Panel Mount
• Connector Style: Rack and Panel
• Connector Usage: Receptacle
• Features: Mating Guide

The QR/P4-16S-C(21) meets all substitution criteria. While the housing color differs (blue versus black), this is a cosmetic variation that does not affect electrical or mechanical compatibility. Both parts share identical connector geometry, pitch spacing, position count, and mounting configuration.

Parameter Comparison

Engineering Selection Recommendations

The QR/P4-16S-C(21) is the direct substitute for the obsolete QR/P4-16S-C(01). Both parts are manufactured by Hirose Electric Co Ltd and maintain identical electrical and mechanical specifications across all critical parameters including connector geometry, pitch, position count, and mounting configuration.

The QR/P4-16S-C(21) offers the additional advantage of active product status, ensuring continued availability and supply chain reliability. The part meets ROHS3 compliance, exceeding the RoHS compliance level of the original part. Both parts carry identical export classification (EAR99) and tariff codes (8536.69.4030), simplifying procurement and regulatory documentation.

The housing color difference (blue versus black) is a cosmetic variation with no impact on electrical performance or mechanical interchangeability.

Frequently Asked Questions (FAQ)

Q: Can the QR/P4-16S-C(21) directly replace the QR/P4-16S-C(01)?

A: Yes. Both parts share identical connector type, position count (16), pitch (0.100"/2.54mm), row configuration (2), mounting type (panel mount), and connector style (rack and panel). All electrical and mechanical parameters are equivalent.

Q: Does the housing color difference affect compatibility?

A: No. Housing color is a cosmetic specification that does not affect electrical performance, mechanical fit, or mating characteristics. The color difference does not impact interchangeability.

Q: Why is the original part listed as obsolete?

A: Product status reflects manufacturer lifecycle decisions. The QR/P4-16S-C(21) is actively manufactured and represents the current production equivalent.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS compliant. The QR/P4-16S-C(21) meets the more recent ROHS3 standard. Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4030) classifications.

Q: What is the packaging difference?

A: The QR/P4-16S-C(01) packaging is not specified in available data. The QR/P4-16S-C(21) is supplied in bulk packaging. Confirm packaging requirements with your procurement specification.

Q: Are contacts included with these housings?

A: No. Both parts are housings only. Contacts must be procured separately and are not included.
