Key Parameters

Substitute Part Grouping Explanation

Substitution of the SSW-135-21-G-S is determined by strict equivalence across the following critical parameters:

• Connector Type & Position Count: Both parts must be 35-position receptacles
• Pitch & Mating Interface: 0.100" (2.54mm) pitch for mechanical and electrical compatibility
• Contact Configuration: Forked contact type with identical contact material (Phosphor Bronze) and finish specifications
• Mounting & Termination: Through-hole solder termination with push-pull fastening
• Electrical Performance: 4.7A per contact current rating and operating temperature range of -55°C ~ 125°C
• Compliance & Material: UL94 V-0 flammability rating, LCP insulation material, and ROHS3 compliance

The substitute part SSW-135-01-G-S meets all these criteria and is therefore electrically and mechanically interchangeable with the SSW-135-21-G-S within the SSW series.

Parameter Comparison

Engineering Selection Recommendations

Both the SSW-135-21-G-S and SSW-135-01-G-S are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Inventory Availability: SSW-135-01-G-S has 1138 units in stock compared to 1038 units for SSW-135-21-G-S
• Compliance Requirements: Both parts meet ROHS3 compliance and UL94 V-0 flammability standards
• Supply Chain Continuity: Either part provides equivalent functionality for board-to-board or cable applications requiring 35-position 0.100" pitch connectors
• Regulatory Classification: Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications

Frequently Asked Questions (FAQ)

Q: Are SSW-135-21-G-S and SSW-135-01-G-S mechanically interchangeable?

A: Yes. Both connectors have identical mounting type (through-hole), pitch (0.100"), position count (35), and fastening mechanism (push-pull). They mount identically on PCBs and mate with the same plug connectors.

Q: Can I substitute SSW-135-01-G-S for SSW-135-21-G-S in an existing design?

A: Yes. All electrical parameters, contact specifications, and environmental ratings are identical. No design changes are required.

Q: What is the difference between these two part numbers?

A: The part numbers differ only in their suffix designation (-21-G-S versus -01-G-S). All functional, electrical, and mechanical specifications are equivalent within the SSW series.

Q: Are both parts RoHS compliant?

A: Yes. Both SSW-135-21-G-S and SSW-135-01-G-S are ROHS3 compliant.

Q: What is the current rating per contact?

A: Both parts are rated for 4.7A per contact at the specified operating temperature range of -55°C ~ 125°C.

Q: Do these connectors require any special handling or storage?

A: Both parts have Moisture Sensitivity Level (MSL) listed as Not Applicable, indicating standard handling and storage conditions are acceptable.
