• Pitch spacing (0.100" / 2.54mm)
• Number of rows (3)
• Row spacing (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Termination type (Solder)
• Contact finish at mating surface (Gold)
• Current rating per contact (4.7A)
• Operating temperature range (-55°C ~ 125°C)
• Flammability rating (UL94 V-0)
• RoHS compliance status (ROHS3 Compliant)

The identified substitute part SSW-109-21-L-T meets all these criteria, confirming functional and mechanical interchangeability within the SSW series rectangular connector family.

Frequently Asked Questions (FAQ)

Q: Can SSW-109-21-L-T replace SSW-109-01-L-T in existing designs?

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

Q: Are there differences in PCB footprint between these parts?

A: No. Both parts share identical mechanical dimensions: 27 positions in 3 rows with 0.100" (2.54mm) pitch and row spacing, 0.335" (8.51mm) insulation height, and 0.104" (2.64mm) contact post length.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SSW-109-01-L-T and SSW-109-21-L-T are ROHS3 compliant and carry UL94 V-0 flammability certification. Both are classified as EAR99 for export control purposes.

Q: What is the current rating for these connectors?

A: Both parts are rated for 4.7A per contact, supporting the same power delivery specifications across all 27 positions.

Q: Are the contact materials identical?

A: Yes. Both parts use phosphor bronze contacts with gold plating (10.0µin / 0.25µm thickness) at the mating surface and tin plating at the post termination.

Q: What is the operating temperature range?

A: Both parts operate across -55°C to 125°C, suitable for industrial and extended temperature applications.
