SSW-108-22-S-S-RA Equivalent & Substitute Parts

Part Overview

The SSW-108-22-S-S-RA is an 8-position receptacle connector manufactured by Samtec Inc., designed for board-to-board or cable applications with 0.100" (2.54mm) pitch spacing. This through-hole, right-angle connector features gold-plated mating contacts and tin-plated posts, rated for 4.7A per contact with an operating temperature range of -55°C to 125°C. The connector is constructed from liquid crystal polymer (LCP) insulation material and meets UL94 V-0 flammability standards. As an active product with ROHS3 compliance and MSL 1 rating, substitute parts may be required for design flexibility, inventory optimization, or specific application requirements while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the SSW-108-22-S-S-RA are qualified based on strict equivalence across the following critical parameters:

• Connector Type & Position Count: All substitutes must be 8-position receptacle connectors
• Pitch Specification: Mating pitch must be 0.100" (2.54mm)
• Mounting Configuration: Through-hole, right-angle mounting required
• Contact System: Forked contact type with gold mating finish and tin post finish
• Electrical Rating: 4.7A per contact minimum
• Temperature Range: -55°C to 125°C operating range
• Material & Compliance: Liquid crystal polymer insulation, UL94 V-0 flammability rating, ROHS3 compliance

The identified substitute parts SSW-108-02-S-S-RA and SSW-108-02-SM-S-RA meet all these criteria and share the same base product number (SSW-108), confirming functional and mechanical interchangeability within the SSW series rectangular connector family.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SSW-108-22-S-S-RA, SSW-108-02-S-S-RA, and SSW-108-02-SM-S-RA—are active products from Samtec Inc. with identical electrical, mechanical, and compliance specifications. Each part maintains ROHS3 compliance, REACH unaffected status, and EAR99 export classification. The parts are functionally equivalent for applications requiring 8-position, 0.100" pitch receptacle connectors with gold mating contacts and 4.7A per contact current capacity across the -55°C to 125°C temperature range.

Selection between these parts should be based on inventory availability and packaging requirements. Current stock levels are: SSW-108-22-S-S-RA (791 pcs), SSW-108-02-S-S-RA (752 pcs), and SSW-108-02-SM-S-RA (934 pcs). The MSL rating differs between SSW-108-22-S-S-RA (MSL 1, Unlimited) and SSW-108-02-SM-S-RA (MSL Not Applicable), which may influence handling and storage procedures in moisture-sensitive environments.

Frequently Asked Questions (FAQ)

Q: Are SSW-108-02-S-S-RA and SSW-108-02-SM-S-RA direct substitutes for SSW-108-22-S-S-RA?

A: Yes. All three parts share identical electrical ratings (4.7A per contact), mechanical dimensions (8-position, 0.100" pitch, through-hole right-angle), contact finishes (gold mating, tin post), and compliance certifications (ROHS3, UL94 V-0). They are functionally interchangeable within the SSW series.

Q: What is the difference between these substitute parts?

A: The primary differences are in packaging designation and moisture sensitivity level. SSW-108-02-SM-S-RA has an MSL rating of Not Applicable, while SSW-108-22-S-S-RA has MSL 1 (Unlimited). The part number variations reflect different packaging or configuration codes within the Samtec SSW series, but electrical and mechanical performance remain equivalent.

Q: Can these connectors be used interchangeably on the same PCB?

A: Yes. All parts feature identical through-hole, right-angle mounting configurations with matching insulation heights (0.095"), contact post lengths (0.100"), and pitch spacing (0.100"). PCB footprints and mating interfaces are compatible across all three parts.

Q: What are the compliance and regulatory considerations?

A: All three parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. They meet UL94 V-0 flammability standards and are suitable for applications requiring these certifications.

Q: Are there any temperature or current limitations?

A: No. All substitute parts operate across the identical temperature range (-55°C to 125°C) and support the same current rating (4.7A per contact). There are no derating considerations between these parts.
