SSW-102-22-F-D-RA Equivalent & Substitute Parts

Part Overview

The SSW-102-22-F-D-RA is a 4-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 mounted connector features gold-plated mating contacts and tin-plated posts, rated for 4.7A per contact across an operating temperature range of -55°C to 125°C. The connector is constructed from liquid crystal polymer (LCP) insulation material with UL94 V-0 flammability rating and maintains ROHS3 compliance. Substitute parts are identified when electrical and mechanical parameters remain identical across connector specifications, ensuring direct interchangeability in circuit board designs.

Engineering Selection Recommendations

All three part numbers—SSW-102-22-F-D-RA, SSW-102-02-F-D-RA, and SSW-102-02-FM-D-RA—are active products from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts is based on inventory availability and application requirements:

SSW-102-22-F-D-RA: 690 units in stock
SSW-102-02-F-D-RA: 958 units in stock
SSW-102-02-FM-D-RA: 1057 units in stock

All parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications. The identical parameter set across all three part numbers confirms direct substitution capability without design modification or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can SSW-102-02-F-D-RA and SSW-102-02-FM-D-RA be used interchangeably with SSW-102-22-F-D-RA?

A: Yes. All three part numbers share identical electrical and mechanical specifications, including connector type, position count, pitch spacing, mounting orientation, contact finishes, current rating, and operating temperature range. Direct substitution is supported without circuit board redesign.

Q: What determines substitution eligibility for these rectangular connectors?

A: Substitution is determined by equivalence across connector configuration (4-position, 2-row), pitch specifications (0.100" mating and row spacing), mounting type (through-hole, right-angle), contact specifications (forked, phosphor bronze, gold/tin finish), electrical performance (4.7A per contact), and environmental compliance (UL94 V-0, ROHS3, -55°C to 125°C operating range).

Q: Are there differences in contact finish thickness between these parts?

A: No. All three parts specify 3.00µin (0.076µm) contact finish thickness on mating surfaces, with identical tin post finish specifications.

Q: Which part should be selected based on availability?

A: Selection should prioritize inventory levels: SSW-102-02-FM-D-RA (1057 units), SSW-102-02-F-D-RA (958 units), or SSW-102-22-F-D-RA (690 units). All parts are equivalent for design purposes.

Q: Do these connectors require different PCB footprints?

A: No. Identical mounting type (through-hole, right-angle), pitch spacing (0.100"), and row configuration ensure all three parts use the same PCB footprint and assembly process.
