Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSW-104-21-G-S is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Number of positions (4)
• Pitch specification (0.100" / 2.54mm)
• Contact type (Forked)
• Mounting method (Through Hole)
• Termination type (Solder)
• Fastening mechanism (Push-Pull)
• Contact finish (Gold)
• Current rating (4.7A per Contact)
• Operating temperature range (-55°C ~ 125°C)
• Flammability rating (UL94 V-0)
• RoHS compliance (ROHS3)

The identified substitute part SSW-104-01-G-S meets all these criteria and belongs to the same SSW series base product family (SSW-104).

Parameter Comparison

Engineering Selection Recommendations

Both SSW-104-21-G-S and SSW-104-01-G-S are active production parts with full ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and supply chain requirements. The SSW-104-01-G-S offers higher stock availability (2715 units) compared to SSW-104-21-G-S (934 units), making it suitable for high-volume applications or when extended lead times must be minimized. Both parts carry identical certifications (UL94 V-0, EAR99, HTSUS 8536.69.4040) and are functionally interchangeable within the same application context.

Frequently Asked Questions (FAQ)

Q: Are SSW-104-21-G-S and SSW-104-01-G-S electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including 4.7A per contact current rating, -55°C to 125°C operating temperature range, and gold-plated contact finishes with matching thickness specifications.

Q: What are the mechanical compatibility requirements?

A: Both connectors feature identical mechanical parameters: 4-position configuration, 0.100" (2.54mm) pitch, through-hole solder termination, push-pull fastening, and 0.335" (8.51mm) insulation height. They are mechanically interchangeable in PCB layouts designed for the SSW-104 base product family.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SSW-104-21-G-S and SSW-104-01-G-S are ROHS3 compliant, carry UL94 V-0 flammability ratings, and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What is the primary difference between these two part numbers?

A: The primary difference is inventory availability. SSW-104-01-G-S has significantly higher stock levels (2715 units) compared to SSW-104-21-G-S (934 units). All electrical, mechanical, and compliance specifications are identical.

Q: Can I use SSW-104-01-G-S as a direct replacement in existing designs?

A: Yes. Since both parts are from the same SSW-104 base product family with identical specifications, SSW-104-01-G-S functions as a direct substitute without design modifications or re-qualification requirements.
