SSW-103-21-F-S Equivalent & Substitute Parts

Part Overview

The SSW-103-21-F-S is a 3-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 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 pitch configurations.

Equivalent parts are necessary when primary inventory is unavailable, when supply chain optimization is required, or when design flexibility allows for functionally identical alternatives that meet the same electrical and mechanical specifications.

These parts are electrically and mechanically interchangeable within the same application context.

Parameter Comparison

Engineering Selection Recommendations

Both SSW-103-21-F-S and SSW-103-01-F-S are Active status products from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on:

Inventory Availability: SSW-103-01-F-S currently has 2336 pcs in stock compared to 719 pcs for SSW-103-21-F-S, providing greater supply security for high-volume applications.

Compliance Status: Both parts are ROHS3 compliant and carry EAR99 export classification, meeting current regulatory requirements for commercial and industrial applications.

Moisture Sensitivity: SSW-103-01-F-S is rated MSL 1 (Unlimited), while SSW-103-21-F-S is Not Applicable. This distinction does not affect substitution suitability for standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can SSW-103-01-F-S be used as a direct replacement for SSW-103-21-F-S?

A: Yes. Both parts are identical in electrical and mechanical specifications, including connector type, position count, pitch, contact materials, finishes, current rating, and operating temperature range. Direct substitution is permissible without circuit or layout modifications.

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

A: No. Both parts feature gold-plated mating contacts (3.00µin thickness) and tin-plated posts. Contact material, shape, and dimensions are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SSW-103-21-F-S and SSW-103-01-F-S are ROHS3 compliant, UL94 V-0 rated, and classified as EAR99 for export purposes.

Q: What is the difference between MSL 1 (Unlimited) and Not Applicable?

A: MSL 1 (Unlimited) indicates the part has no moisture sensitivity restrictions during storage and handling. Not Applicable indicates the part does not require moisture sensitivity classification. This does not affect interchangeability for standard assembly environments.

Q: Are the physical dimensions identical?

A: Yes. Insulation height (0.335"), contact length (0.104"), and all other mechanical dimensions are identical between both parts.

Q: Can these connectors be used in high-temperature applications?

A: Both parts operate across -55°C to 125°C, suitable for industrial and commercial temperature ranges. Specific application requirements should be evaluated against this operating window.
