Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSW-128-22-S-D is determined by the following critical parameters:

• Number of Positions: 56
• Pitch - Mating: 0.100" (2.54mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Connector Type: Receptacle
• Mounting Type: Through Hole
• Termination: Solder
• Contact Finish - Mating: Gold
• Current Rating: 4.7A per Contact
• Operating Temperature Range: -55°C ~ 125°C
• Insulation Material: Liquid Crystal Polymer (LCP)
• Material Flammability Rating: UL94 V-0

The substitute part SSW-128-02-S-D matches all critical electrical and mechanical parameters, maintaining identical contact configuration, pitch spacing, termination method, and environmental ratings. Both parts belong to the SSW series and share the same base product number (SSW-128), confirming functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both SSW-128-22-S-D and SSW-128-02-S-D are active production parts from Samtec Inc. with full ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and lead time requirements. The SSW-128-02-S-D currently has 1178 units in stock compared to 1127 units for the SSW-128-22-S-D. Both parts meet UL94 V-0 flammability requirements and are suitable for applications requiring -55°C to 125°C operating temperature range with 4.7A per contact current capacity.

Frequently Asked Questions (FAQ)

Q: Are SSW-128-22-S-D and SSW-128-02-S-D fully interchangeable?

A: Yes. Both parts share identical electrical and mechanical specifications including 56-position configuration, 0.100" (2.54mm) pitch, through-hole solder termination, gold-plated mating contacts, and operating temperature range. They are functionally equivalent within the SSW series.

Q: What determines substitution eligibility for SSW-128 series connectors?

A: Substitution is valid when parts maintain matching position count (56), mating pitch (0.100"), row configuration (2 rows), contact finish (gold), termination method (solder), and environmental ratings (UL94 V-0, -55°C to 125°C).

Q: Do both parts have the same PCB footprint?

A: Yes. Both connectors feature identical mounting specifications: through-hole termination, 0.335" (8.51mm) insulation height, 0.194" (4.93mm) contact post length, and 0.100" (2.54mm) row spacing.

Q: Are there compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, carry EAR99 ECCN classification, and share identical HTSUS code 8536.69.4040.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should consider current inventory levels and supply chain requirements. The SSW-128-02-S-D has higher current stock availability.
