SSW-113-22-S-D-RA Equivalent & Substitute Parts

Part Overview

The SSW-113-22-S-D-RA is a 26-position receptacle connector manufactured by Samtec Inc., designed for board-to-board or cable applications with through-hole, right-angle mounting. This connector features gold-plated mating contacts and tin-plated posts, operating across -55°C to 125°C with a current rating of 4.7A per contact. The part is Active status and ROHS3 compliant, making it suitable for modern electronic assemblies requiring reliable interconnection in standard 0.100" pitch configurations.

Substitute parts become necessary when addressing inventory constraints, lead time requirements, or specific manufacturing preferences while maintaining electrical and mechanical compatibility within the SSW series.

Substitute Part Grouping Explanation

Substitution within the SSW-113 series is determined by the following critical parameters that remain constant across all equivalent parts:

Connector type (Receptacle)
Position count (26 positions)
Mating pitch (0.100" / 2.54mm)
Row configuration (2 rows at 0.100" spacing)
Mounting style (Through hole, right angle)
Contact finish specifications (Gold mating, tin post)
Electrical ratings (4.7A per contact)
Temperature range (-55°C ~ 125°C)
Compliance certifications (UL94 V-0, ROHS3)

The substitute parts SSW-113-02-S-D-RA and SSW-113-02-SM-D-RA maintain identical electrical and mechanical characteristics, differing only in internal design variations within the SSW-113 base product family that do not affect connector performance or interchangeability.

Engineering Selection Recommendations

All three parts—SSW-113-22-S-D-RA, SSW-113-02-S-D-RA, and SSW-113-02-SM-D-RA—are Active status products with identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and lead time requirements rather than technical performance differences.

SSW-113-02-S-D-RA offers the highest current inventory (2049 pcs), making it the preferred choice for immediate procurement needs. SSW-113-02-SM-D-RA provides an alternative with 972 pcs in stock. The original SSW-113-22-S-D-RA maintains 816 pcs in inventory.

All parts meet ROHS3 compliance and UL94 V-0 flammability requirements, ensuring suitability for regulated applications. No technical re-qualification is necessary when substituting between these parts within the same design.

Frequently Asked Questions (FAQ)

Q: Are SSW-113-02-S-D-RA and SSW-113-02-SM-D-RA fully interchangeable with SSW-113-22-S-D-RA?

A: Yes. All three parts share identical electrical ratings (4.7A per contact), mechanical dimensions (26 positions, 0.100" pitch, 2-row configuration), contact finishes (gold mating, tin post), and operating temperature range (-55°C ~ 125°C). They are direct substitutes within the SSW-113 series.

Q: What determines substitution eligibility within the SSW-113 series?

A: Substitution is valid when the following parameters remain constant: connector type (receptacle), position count (26), mating pitch (0.100"), row configuration (2 rows), mounting style (through hole, right angle), contact finish specifications, and electrical ratings. All three listed parts meet these criteria.

Q: Do these parts require different PCB footprints?

A: No. All three parts maintain identical through-hole mounting specifications, insulation height (0.195"), and contact post length (0.100"), ensuring compatibility with the same PCB layout.

Q: Are there compliance or certification differences between these parts?

A: No. All three parts are ROHS3 compliant, UL94 V-0 rated, and classified under the same ECCN (EAR99) and HTSUS (8536.69.4040) codes.

Q: Which part should be selected for new designs?

A: Any of the three parts is suitable for new designs. Selection should prioritize inventory availability and supplier lead times, as all parts are Active status with identical performance characteristics.
