Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSW-112-21-S-S-LL is determined by strict equivalence across the following critical parameters:

• Connector Type & Position Count: Receptacle configuration with 12 positions
• Pitch & Mounting: 0.100" (2.54mm) mating pitch with through-hole mounting
• Contact System: Forked contact type with kinked pin solder termination
• Electrical Performance: 4.7A per contact current rating and -55°C ~ 125°C operating temperature range
• Contact Finish: Gold plating on mating surface at 30.0µin (0.76µm) thickness with tin finish on post
• Material & Compliance: Liquid Crystal Polymer insulation, UL94 V-0 flammability rating, and ROHS3 compliance

The substitute part SSW-112-01-S-S-LL maintains identical specifications across all these parameters, differing only in the connector variant designation within the SSW series base product number SSW-112.

Parameter Comparison

Both parts satisfy identical electrical, mechanical, and environmental specifications for 12-position, 0.100" pitch through-hole receptacle applications with 4.7A per contact current capacity and -55°C ~ 125°C operating range.

Frequently Asked Questions (FAQ)

Q: Can SSW-112-01-S-S-LL be used as a direct replacement for SSW-112-21-S-S-LL?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters, including connector type, position count, pitch, mounting method, contact finish, current rating, and operating temperature range.

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

A: The difference lies in the connector variant designation within the SSW series. The "21" and "01" designations indicate different connector variants, but the electrical and mechanical specifications remain identical for this application.

Q: Are there any compatibility concerns with PCB layout or mating components?

A: No compatibility concerns exist. Both connectors share identical pitch (0.100"), mounting type (through-hole), and contact configuration, ensuring direct compatibility with existing PCB designs and mating connectors.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SSW-112-21-S-S-LL and SSW-112-01-S-S-LL are ROHS3 compliant with UL94 V-0 material flammability rating and identical environmental specifications.

Q: Which part should be selected based on availability?

A: Selection should prioritize inventory levels and procurement lead times. SSW-112-21-S-S-LL offers higher stock availability at 1186 units, while SSW-112-01-S-S-LL provides an alternative source with 613 units in stock.
