Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSW-122-22-S-D-RA is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Number of positions (44)
• Pitch and row spacing (0.100" / 2.54mm)
• Mounting configuration (Through Hole, Right Angle)
• Contact finish specifications (Gold mating, Tin post)
• Current rating (4.7A per contact)
• Operating temperature range (-55°C ~ 125°C)
• Compliance certifications (UL94 V-0, ROHS3)

The SSW-122-02-S-D-RA qualifies as a direct substitute based on identical electrical and mechanical parameters across all critical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the SSW-122-22-S-D-RA and SSW-122-02-S-D-RA are actively produced components with identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and supply chain considerations. Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, ensuring regulatory conformance for industrial applications. The SSW-122-02-S-D-RA currently maintains higher inventory levels (1049 pcs vs. 857 pcs), which may provide supply chain advantages for high-volume procurement.
