PC-1634 Equivalent & Substitute Parts Reference

Part Overview

The PC-1634 is a 34-position rectangular connector housing manufactured by Hirose Electric Co Ltd as part of the Sumicon 1600 series. This plug housing is designed for male pin contacts with a crimp termination method and features a flange for secure mounting in free-hanging inline applications. The part is currently classified as obsolete, making identification of compatible substitute components essential for ongoing system maintenance and new design implementations. The PC-1634(10) variant provides an active production alternative within the same product family.

Key Parameters

Substitute Part Grouping Explanation

The PC-1634(10) qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

• Connector Type & Contact Configuration: Both parts are plug housings with male pin contacts in a 34-position, 3-row configuration
• Mechanical Interface: Identical mounting type (free hanging in-line) and flange feature ensure physical compatibility
• Termination Method: Both use crimp contact termination, maintaining assembly process compatibility
• Material & Environmental Rating: Resin insulation material and MSL 1 rating are identical across both parts
• Series Alignment: Both belong to the Hirose Sumicon 1600 series, confirming design family compatibility

The primary distinction is product status: PC-1634 is obsolete while PC-1634(10) maintains active production status, and color differentiation (blue vs. black housing).

Parameter Comparison

Engineering Selection Recommendations

For applications currently using PC-1634, the PC-1634(10) serves as the functional equivalent for new procurement and system redesigns. The PC-1634(10) maintains all critical electrical and mechanical parameters while offering the advantage of active production status and RoHS compliance certification. The color difference (blue to black housing) is a cosmetic variation that does not affect electrical performance or mechanical fit within the Sumicon 1600 connector family. Selection of PC-1634(10) eliminates obsolescence risk and ensures long-term component availability.

Frequently Asked Questions (FAQ)

Q: Can PC-1634(10) be used as a direct replacement for PC-1634 in existing assemblies?

A: Yes. Both parts share identical connector type, position count, row configuration, mounting method, and contact termination. The housing color difference does not affect functional compatibility or electrical performance.

Q: What is the significance of the product status difference?

A: PC-1634 is classified as obsolete, meaning Hirose Electric has discontinued production. PC-1634(10) maintains active production status, ensuring availability for future orders and system maintenance.

Q: Does the RoHS compliance status of PC-1634(10) affect compatibility?

A: RoHS compliance is an environmental and regulatory attribute that does not impact electrical or mechanical compatibility. PC-1634(10) meets additional regulatory requirements while maintaining full functional equivalence.

Q: Are the crimp contact specifications identical between both parts?

A: Both parts use crimp contact termination and belong to the same Sumicon 1600 series. Contact specifications are determined by the series design, ensuring compatibility with the same contact pin sets.

Q: What packaging differences exist between these parts?

A: PC-1634 packaging is not specified in available data. PC-1634(10) is supplied in bulk packaging. Packaging format does not affect component functionality or mechanical fit.
