SC-1634 Equivalent & Substitute Parts

Part Overview

The SC-1634 is a 34-position rectangular connector housing manufactured by Hirose Electric Co Ltd, part of the Sumicon 1600 series. This receptacle housing features female socket contacts, a blue insulation body with flange mounting, and is designed for free-hanging in-line applications with crimp termination. The part is classified as obsolete, making identification of compatible alternatives essential for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC-1634 is determined by strict equivalence across the following critical parameters: manufacturer (Hirose Electric Co Ltd), series (Sumicon 1600), connector type (receptacle), contact type (female socket), number of positions (34), number of rows (3), mounting type (free hanging in-line), contact termination method (crimp), features (flange), and insulation material (resin). The SC-1634(10) satisfies all these criteria, with the only variation being color (black versus blue) and product status (active versus obsolete). Color variation does not affect electrical or mechanical compatibility when the connector housing is the functional requirement.

Parameter Comparison

Engineering Selection Recommendations

The SC-1634(10) is the direct equivalent substitute for the SC-1634. Both parts share identical electrical and mechanical specifications within the Sumicon 1600 series. The SC-1634(10) offers the advantage of active product status and RoHS compliance certification, making it the preferred selection for new designs and ongoing procurement. The color difference (black versus blue) is a cosmetic variation that does not affect connector function, mating capability, or electrical performance. Current inventory availability of 1,071 units for SC-1634(10) supports reliable supply chain continuity compared to the obsolete SC-1634.

Frequently Asked Questions (FAQ)

Q: Can SC-1634(10) directly replace SC-1634 in existing assemblies? A: Yes. Both parts are identical in all electrical and mechanical parameters. The housing color difference does not affect mating, contact engagement, or signal integrity.

Q: What is the significance of the product status difference? A: SC-1634 is obsolete and no longer manufactured. SC-1634(10) is active production, ensuring long-term availability and supply chain reliability for component procurement.

Q: Does RoHS compliance affect compatibility? A: No. RoHS compliance is a manufacturing and environmental standard that does not alter the connector's electrical or mechanical function. SC-1634(10) meets this compliance requirement, which is beneficial for regulatory adherence.

Q: Are contacts included with these housings? A: No. Both SC-1634 and SC-1634(10) are housings only. Contacts must be procured separately and crimped into the housing according to Hirose specifications.

Q: What packaging format is available for SC-1634(10)? A: SC-1634(10) is supplied in bulk packaging, suitable for production assembly and component stocking.
