Substitute Part Grouping Explanation

Substitution for the SSW-109-21-S-S-LL is determined by strict equivalence across the following critical parameters:

• Connector Type & Position Count: Receptacle configuration with 9 positions
• Pitch & Mating Interface: 0.100" (2.54mm) pitch for mechanical and electrical compatibility
• Mounting & Termination: Through-hole mounting with kinked pin solder termination
• Contact Specifications: Gold-plated mating contacts at 30.0µin (0.76µm) thickness; tin-plated posts
• Electrical Performance: 4.7A per contact current rating
• Environmental & Compliance: Operating temperature range -55°C ~ 125°C; UL94 V-0 flammability; ROHS3 compliance

The substitute part SSW-109-01-S-S-LL matches all critical parameters and belongs to the same SSW series base product family (SSW-109), confirming direct substitutability.

Parameter Comparison

Engineering Selection Recommendations

Both SSW-109-21-S-S-LL and SSW-109-01-S-S-LL are active production parts with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts is based on inventory availability and supply chain requirements rather than electrical or mechanical differences. The SSW-109-01-S-S-LL offers higher current inventory (963 units versus 807 units), supporting expedited procurement timelines. Both parts meet identical performance specifications for 9-position, 0.100" pitch receptacle applications with 4.7A per contact current capacity and -55°C to 125°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can SSW-109-01-S-S-LL be used as a direct replacement for SSW-109-21-S-S-LL?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical connector type, position count, pitch, mounting method, termination style, contact finish specifications, current rating, and operating temperature range. No design modifications are required for substitution.

Q: Are there any differences in PCB footprint or mounting hole spacing?

A: No differences are specified in the provided parameters. Both parts feature identical through-hole mounting configuration with 0.100" (2.54mm) pitch and 0.335" (8.51mm) insulation height, ensuring identical PCB footprint compatibility.

Q: Do both parts meet the same compliance and certification standards?

A: Yes. Both SSW-109-21-S-S-LL and SSW-109-01-S-S-LL are ROHS3 compliant and carry UL94 V-0 flammability certification. Both are classified as active production parts with no known obsolescence risk.

Q: What is the difference between the part numbers if they are equivalent?

A: The part numbers differ in the fifth and sixth positions (21 versus 01), indicating a variation within the SSW-109 base product family. This variation does not affect the electrical or mechanical parameters relevant to substitution. The difference may relate to internal manufacturing or configuration codes not specified in the provided technical data.

Q: Can these connectors be used in high-temperature applications?

A: Both parts are rated for operating temperatures from -55°C to 125°C. Applications requiring operation outside this range are not supported by these specifications.
