Key Parameters

Substitute Part Grouping Explanation

Substitution within the SSW-135 series is determined by strict equivalence across the following critical parameters:

• Connector Type & Position Count: Both main and substitute parts must be 70-position receptacles
• Pitch & Row Configuration: Mating pitch of 0.100" (2.54mm) with 2-row layout and 0.100" row spacing
• Mounting & Termination: Through-hole solder termination required
• Contact Specifications: Forked contact geometry with gold mating finish and 4.7A per contact current rating
• Environmental & Compliance: Operating temperature range -55°C ~ 125°C, UL94 V-0 flammability rating, and ROHS3 compliance

The SSW-135-01-F-D qualifies as a direct substitute based on identical electrical and mechanical parameters across all specified criteria.

Parameter Comparison

Engineering Selection Recommendations

Both SSW-135-21-F-D and SSW-135-01-F-D maintain Active product status with full ROHS3 compliance and identical electrical performance specifications. Selection between these parts is based on inventory availability and supply chain considerations. The SSW-135-21-F-D currently maintains 1114 pcs in stock, while the SSW-135-01-F-D maintains 932 pcs in stock. Both parts satisfy identical application requirements for 70-position board-to-board or cable connectivity with 0.100" pitch spacing and 4.7A per contact current capacity across the -55°C to 125°C operating range.

Frequently Asked Questions (FAQ)

Q: Can SSW-135-01-F-D be used as a direct replacement for SSW-135-21-F-D?

A: Yes. Both parts are 70-position receptacle connectors with identical electrical and mechanical specifications, including pitch, row configuration, contact geometry, current rating, and operating temperature range. They are functionally interchangeable within the same application.

Q: What determines substitution eligibility for SSW-135 series connectors?

A: Substitution requires equivalence across connector type, position count, mating pitch, row spacing, mounting method, termination type, contact finish, current rating, and operating temperature range. Deviation in any of these parameters disqualifies a part as a direct substitute.

Q: Are there any compliance differences between these substitute parts?

A: No. Both parts carry identical ROHS3 compliance status, UL94 V-0 flammability rating, and EAR99 export classification. Compliance certifications are equivalent.

Q: How do the part numbers differ between SSW-135-21-F-D and SSW-135-01-F-D?

A: The part numbers differ in the third and fourth digit positions (21 versus 01), indicating different configurations within the SSW-135 base product family. Despite this designation difference, the electrical and mechanical parameters provided are identical, supporting direct substitution.

Q: What is the current rating per contact for these connectors?

A: Both connectors are rated for 4.7A per contact, supporting applications requiring moderate current distribution across the 70-position array.
