Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSW-122-21-F-D is determined by strict equivalence across the following parameters:

• Connector position count: 44 positions (non-negotiable)
• Mating pitch: 0.100" (2.54mm) (non-negotiable)
• Row configuration: 2 rows at 0.100" (2.54mm) spacing (non-negotiable)
• Termination method: Solder through-hole (non-negotiable)
• Contact finish - mating surface: Gold plating (non-negotiable)
• Operating temperature range: -55°C ~ 125°C (non-negotiable)
• Flammability rating: UL94 V-0 (non-negotiable)
• RoHS compliance: ROHS3 Compliant (non-negotiable)

The SSW-122-01-F-D meets all substitution criteria and is classified as a direct equivalent within the SSW series.

Parameter Comparison

Engineering Selection Recommendations

Both SSW-122-21-F-D and SSW-122-01-F-D maintain Active product status with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts is based on inventory availability and supply chain considerations. The SSW-122-01-F-D offers higher inventory levels (1193 pcs vs. 724 pcs), providing improved procurement flexibility. Both parts are manufactured by Samtec Inc. and carry identical electrical and mechanical specifications, ensuring direct interchangeability in board-to-board and cable connector applications.

Frequently Asked Questions (FAQ)

Q: Can SSW-122-01-F-D replace SSW-122-21-F-D in existing designs?

A: Yes. Both connectors are electrically and mechanically identical across all critical parameters: 44-position configuration, 0.100" pitch, through-hole solder termination, gold mating contacts, and -55°C to 125°C operating range. No design modification is required.

Q: What determines substitution eligibility for SSW series connectors?

A: Substitution requires matching position count, mating pitch, row configuration, termination method, contact finish, operating temperature range, and flammability rating. Variations in any of these parameters disqualify a part as a direct substitute.

Q: Are there differences in contact plating between these parts?

A: No. Both parts feature identical gold plating on mating contacts (3.00µin thickness) and tin plating on post contacts, with phosphor bronze contact material throughout.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SSW-122-21-F-D and SSW-122-01-F-D are ROHS3 compliant, UL94 V-0 rated, and classified under ECCN EAR99 with identical HTSUS coding (8536.69.4040).

Q: What is the primary reason to consider the substitute part?

A: The SSW-122-01-F-D provides higher inventory availability (1193 pcs in stock vs. 724 pcs), reducing procurement lead time while maintaining complete electrical and mechanical equivalence.
