Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications.

Direct substitution is supported without design modification, PCB layout adjustment, or performance impact. Both parts are suitable for applications requiring 62-position rectangular connectors with 0.100" pitch spacing, solder termination, and -55°C to 125°C operating range.

Frequently Asked Questions (FAQ)

Q: Can SSW-131-01-F-D be used as a direct replacement for SSW-131-21-F-D?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including connector configuration, pitch spacing, contact finish, current rating, and operating temperature range. Direct substitution is supported without design changes.

Q: Are there differences in contact configuration between these parts?

A: No. Both parts feature identical 62-position receptacle configuration with 2-row layout, 0.100" mating pitch, forked contact type, gold mating finish, and tin post finish.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SSW-131-21-F-D and SSW-131-01-F-D are ROHS3 compliant and carry UL94 V-0 flammability certification. Both operate across the identical -55°C to 125°C temperature range.

Q: What is the difference between these part numbers?

A: The part numbers differ only in the suffix designation (21-F-D versus 01-F-D). All electrical, mechanical, and environmental specifications are identical. The difference reflects internal Samtec product line organization without affecting functional performance.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection may be based on current inventory availability. SSW-131-01-F-D currently has higher stock levels (1073 pcs), while SSW-131-21-F-D has 864 pcs available.

Q: Are there any PCB layout or mounting considerations when switching between these parts?

A: No. Both parts use identical through-hole solder termination with matching pin configurations, pitch spacing, and mechanical dimensions. No PCB layout modification is required.
