Substitute Part Grouping Explanation

Substitution eligibility for the SSW-128-22-G-D is determined by strict equivalence across the following critical parameters:

• Connector Type: Receptacle
• Number of Positions: 56
• Pitch - Mating: 0.100" (2.54mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Contact Type: Forked
• Contact Finish - Mating: Gold
• Current Rating: 4.7A per Contact
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The SSW-128-02-G-D meets all substitution criteria as a direct equivalent within the SSW series, sharing identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both SSW-128-22-G-D and SSW-128-02-G-D are Active status components manufactured by Samtec Inc. within the SSW series. Selection between these parts is based on inventory availability and supply chain considerations rather than functional differences. Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting equivalent regulatory and safety requirements. The SSW-128-02-G-D currently maintains 761 units in stock compared to 982 units for the SSW-128-22-G-D, providing alternative sourcing when primary inventory is constrained.
