Key Parameters

Substitute Part Grouping Explanation

The SSW-110-21-L-D and SSW-110-01-L-D are functionally equivalent within the SSW series based on the following critical parameters:

• Both maintain identical connector type (Receptacle) and contact configuration (Forked)
• Both support 20 positions with 2 rows at 0.100" (2.54mm) pitch spacing
• Both employ through-hole solder termination with push-pull fastening
• Both feature gold-plated mating contacts with identical contact finish thickness (10.0µin / 0.25µm)
• Both operate across the same temperature range (-55°C ~ 125°C)
• Both meet UL94 V-0 flammability requirements and ROHS3 compliance
• Both deliver 4.7A per contact current rating
• Both utilize Liquid Crystal Polymer (LCP) insulation material with identical insulation height (0.335" / 8.51mm)

Substitution is valid when the application requires these exact electrical and mechanical specifications without deviation.

Parameter Comparison
