SSW-132-21-SM-S Equivalent & Substitute Parts

Part Overview

The SSW-132-21-SM-S is a 32-position receptacle connector manufactured by Samtec Inc., designed for board-to-board or cable applications with 0.100" (2.54mm) pitch through-hole mounting. This connector features gold-plated mating contacts, tin-plated posts, and is rated for 4.7A per contact with an operating temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance and UL94 V-0 flammability rating. Alternative models within the SSW series may be required due to inventory availability, specific application requirements, or design revisions while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

The SSW-132-01-S-S qualifies as a direct substitute for the SSW-132-21-SM-S based on identical electrical and mechanical parameters. Both parts share the same base product number (SSW-132) and maintain compatibility across all critical substitution criteria:

32-position receptacle configuration
0.100" (2.54mm) mating pitch
Through-hole solder termination
Gold mating contact finish (30.0µin / 0.76µm thickness)
Tin post finish
4.7A per contact current rating
-55°C to 125°C operating temperature range
UL94 V-0 flammability rating
ROHS3 compliance
Liquid Crystal Polymer (LCP) insulation material
Square contact geometry with phosphor bronze contact material

The substitution is valid for applications requiring identical electrical performance and mechanical fit within the SSW connector series.

Engineering Selection Recommendations

Both the SSW-132-21-SM-S and SSW-132-01-S-S are active production parts with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on inventory availability and lead time requirements. The SSW-132-21-SM-S currently has 1129 pieces in stock, while the SSW-132-01-S-S has 778 pieces available. Both parts meet identical electrical specifications, mechanical dimensions, and regulatory requirements, making either suitable for direct substitution in applications requiring 32-position 0.100" pitch receptacle connectors with gold mating contacts and 4.7A per contact current capacity.

Frequently Asked Questions (FAQ)

Q: Can SSW-132-01-S-S be used as a direct replacement for SSW-132-21-SM-S?

A: Yes. Both parts share identical electrical and mechanical specifications including connector type, position count, mating pitch, contact finishes, current rating, operating temperature range, and flammability rating. They are interchangeable within the SSW series.

Q: What are the critical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: 32-position receptacle configuration, 0.100" (2.54mm) mating pitch, through-hole solder termination, gold mating contact finish, tin post finish, 4.7A per contact current rating, -55°C to 125°C operating temperature, UL94 V-0 flammability rating, and ROHS3 compliance. All these parameters are identical between the main part and substitute.

Q: Are there any differences in mechanical fit or PCB mounting between these parts?

A: No. Both parts have identical insulation height (0.335" / 8.51mm), contact post length (0.104" / 2.64mm), and through-hole mounting specifications. PCB layout and footprint compatibility is maintained.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the SSW-132-21-SM-S and SSW-132-01-S-S are ROHS3 compliant, carry UL94 V-0 flammability rating, and are classified as EAR99 for export control purposes with identical HTSUS codes (8536.69.4040).

Q: What is the difference between the part numbers SSW-132-21-SM-S and SSW-132-01-S-S?

A: Both parts share the base product number SSW-132. The suffix variations (21-SM-S versus 01-S-S) represent different configurations within the SSW series, but the electrical and mechanical specifications remain identical for substitution purposes.
