SSW-117-21-S-D Equivalent & Substitute Parts

Part Overview

The SSW-117-21-S-D is a 34-position receptacle connector manufactured by Samtec Inc., designed for board-to-board or cable applications with 0.100" (2.54mm) pitch through-hole mounting. This connector features gold-plated mating contacts, forked contact geometry, and push-pull fastening. The product is discontinued at DiGi Electronics, making identification of compatible substitute parts essential for ongoing system support and procurement.

Substitute Part Grouping Explanation

Substitution of the SSW-117-21-S-D is determined by strict alignment of the following electrical and mechanical parameters:

Connector Type & Position Count: Both main and substitute parts must be 34-position receptacles to ensure mating compatibility with existing plug connectors.
Pitch & Row Configuration: The 0.100" (2.54mm) mating pitch and 2-row configuration with 0.100" row spacing are mandatory for PCB footprint compatibility.
Mounting & Termination: Through-hole solder termination is required for direct replacement in existing circuit board designs.
Contact Finish: Gold-plated mating contacts with 30.0µin thickness specification ensure equivalent signal integrity and corrosion resistance.
Fastening Mechanism: Push-pull fastening type must be maintained for connector engagement consistency.
Environmental Compliance: RoHS compliance and UL94 V-0 flammability rating are required for regulatory equivalence.

The TE Connectivity AMP Connectors part 6-534206-7 meets these core substitution criteria as a 34-position receptacle with identical pitch, row spacing, mounting type, and push-pull fastening.

Engineering Selection Recommendations

The 6-534206-7 (TE Connectivity AMP Connectors) is an active product with equivalent core electrical and mechanical specifications to the discontinued SSW-117-21-S-D. Both connectors share identical mating pitch, row configuration, mounting type, fastening mechanism, and contact finish specifications required for PCB footprint compatibility.

The substitute part maintains UL94 V-0 flammability compliance and RoHS regulatory status. The operating temperature range of the substitute (-65°C ~ 125°C) extends below the original part (-55°C ~ 125°C), providing broader environmental coverage.

Differences in insulation height (0.320" vs. 0.335"), contact post length (0.115" vs. 0.104"), and current rating per contact (2A vs. 4.7A) must be evaluated against specific application requirements. The lower current rating of the substitute part may require circuit design review if the original design relied on the 4.7A per-contact specification.

Frequently Asked Questions (FAQ)

Q: Can the 6-534206-7 directly replace the SSW-117-21-S-D in existing designs?

A: The 6-534206-7 shares identical mating pitch (0.100"), row spacing (0.100"), position count (34), and push-pull fastening with the SSW-117-21-S-D, ensuring mechanical and electrical compatibility at the connector interface. However, differences in insulation height and contact post length may affect PCB layout clearances and mating depth. Physical verification against the PCB footprint is required.

Q: What are the key differences between these two connectors?

A: The primary differences are: insulation height (0.320" vs. 0.335"), contact post length (0.115" vs. 0.104"), current rating per contact (2A vs. 4.7A), and insulation material composition (Polyester, Glass Filled vs. Liquid Crystal Polymer). The substitute part also provides an extended lower operating temperature limit (-65°C vs. -55°C).

Q: Is the current rating difference significant for substitution?

A: The 6-534206-7 has a lower current rating (2A per contact) compared to the SSW-117-21-S-D (4.7A per contact). If the original design operates at current levels between 2A and 4.7A per contact, the substitute part may not be suitable without circuit redesign or derating analysis.

Q: Are both connectors RoHS compliant?

A: Yes. The SSW-117-21-S-D is ROHS3 Compliant, and the 6-534206-7 is RoHS Compliant. Both meet regulatory requirements for hazardous substance restrictions.

Q: What is the packaging difference?

A: The SSW-117-21-S-D packaging is not specified in available data. The 6-534206-7 is supplied in Tube packaging.
