Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SSW-104-21-S-S are identified within the SSW-104 base product family. Substitution is valid when the following parameters remain constant:

• Connector type: Receptacle
• Number of positions: 4
• Pitch - mating: 0.100" (2.54mm)
• Mounting type: Through hole
• Contact type: Forked
• Contact finish - mating: Gold
• Contact finish - post: Tin
• Current rating: 4.7A per contact
• Operating temperature: -55°C ~ 125°C
• Insulation material: Liquid Crystal Polymer (LCP)
• Material flammability rating: UL94 V-0
• RoHS status: ROHS3 Compliant

The identified substitutes (SSW-104-01-S-S and SSW-104-01-SM-S) maintain all critical electrical and mechanical parameters, differing only in internal design variations that do not affect functional compatibility in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SSW-104-21-S-S, SSW-104-01-S-S, and SSW-104-01-SM-S—are active production components with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on availability and supply chain requirements. SSW-104-01-S-S offers the highest inventory level at 3911 units, making it the preferred choice for high-volume applications. SSW-104-21-S-S and SSW-104-01-SM-S are suitable alternatives when primary selections are unavailable. All parts meet identical electrical and mechanical specifications for standard board-to-board and cable connector applications.
