Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSW-134-21-S-S is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Number of positions (34)
• Mating pitch (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Contact configuration (Forked contacts)
• Contact finish specifications (Gold mating, Tin post)
• Current rating (4.7A per contact)
• Operating temperature range (-55°C ~ 125°C)
• Insulation material (Liquid Crystal Polymer)
• Flammability rating (UL94 V-0)
• Regulatory compliance (RoHS3)

Parts meeting all these criteria are classified as direct equivalents within the SSW series and are suitable for direct substitution in applications where the SSW-134-21-S-S is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the SSW-134-21-S-S and SSW-134-01-S-S are active production parts manufactured by Samtec Inc. with identical electrical, mechanical, and environmental specifications. Both parts maintain full RoHS3 compliance and carry the same regulatory classifications (ECCN: EAR99, HTSUS: 8536.69.4040). Selection between these parts should be based on inventory availability and lead time requirements, as they are functionally equivalent for all applications where the SSW-134-21-S-S is specified. The SSW-134-01-S-S currently maintains 659 units in stock, while the SSW-134-21-S-S has 1119 units available.

Frequently Asked Questions (FAQ)

Q: Can SSW-134-01-S-S be used as a direct replacement for SSW-134-21-S-S?

A: Yes. Both parts are 34-position receptacle connectors with identical electrical ratings (4.7A per contact), mechanical dimensions, contact finishes, and operating temperature ranges (-55°C ~ 125°C). They are functionally equivalent and interchangeable in all applications.

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

A: No. Both parts feature gold-plated mating contacts (30.0µin / 0.76µm thickness) and tin-plated posts. Contact material, shape, and configuration are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SSW-134-21-S-S and SSW-134-01-S-S are RoHS3 compliant, carry UL94 V-0 flammability ratings, and share identical ECCN and HTSUS classifications.

Q: What is the difference between the part numbers?

A: The part numbers differ only in the third segment (21 versus 01), which indicates a variation within the SSW-134 base product family. All other specifications remain identical, making them direct substitutes.

Q: Are there any packaging or lead time considerations?

A: Both parts are supplied in bulk packaging. Selection should consider current inventory levels and supplier lead times. The SSW-134-01-S-S currently has lower inventory availability (659 units) compared to the SSW-134-21-S-S (1119 units).
