Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SSW-116-21-S-P are qualified based on the following critical parameters that determine functional interchangeability:

• Connector Type & Position Count: All substitutes must be 16-position receptacle connectors
• Pitch & Mating Interface: 0.100" (2.54mm) pitch is mandatory for mechanical compatibility
• Contact Configuration: Forked contact type with gold mating finish and tin post finish
• Electrical Rating: 4.7A per contact minimum
• Mounting & Termination: Through-hole solder termination required
• Environmental Compliance: UL94 V-0 flammability rating and ROHS3 compliance

The identified substitutes SSW-116-01-S-S and SSW-116-01-SM-S meet all these criteria and are manufactured by the same supplier (Samtec Inc.) within the same SSW series, ensuring design compatibility and performance equivalence.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SSW-116-21-S-P, SSW-116-01-S-S, and SSW-116-01-SM-S—are active production components with full ROHS3 compliance and UL94 V-0 flammability certification. The parts are electrically and mechanically equivalent across all specified parameters. Selection between these parts should be based on:

• Availability: SSW-116-21-S-P has the highest inventory (904 units), followed by SSW-116-01-S-S (754 units) and SSW-116-01-SM-S (749 units)
• Supply Chain Requirements: All parts are manufactured by Samtec Inc. and share the same base product number (SSW-116), ensuring consistent quality and lead times
• Design Compatibility: No design modifications are required when substituting between these parts; all mechanical and electrical interfaces are identical

Frequently Asked Questions (FAQ)

Q: Can SSW-116-01-S-S be used as a direct replacement for SSW-116-21-S-P?

A: Yes. Both parts are 16-position receptacle connectors with 0.100" pitch, identical contact configurations, and matching electrical ratings. No circuit board redesign is required.

Q: What is the difference between SSW-116-01-S-S and SSW-116-01-SM-S?

A: Both parts share identical electrical and mechanical specifications as listed in the parameter comparison table. The difference lies in the part number designation, which may reflect internal Samtec manufacturing or packaging variations not specified in the provided data.

Q: Are these connectors suitable for high-temperature applications?

A: Yes. All three parts are rated for -55°C to 125°C operating temperature with UL94 V-0 flammability rating, making them suitable for industrial and automotive applications within this temperature range.

Q: What is the current-carrying capacity per contact?

A: Each contact is rated for 4.7A maximum current. Total circuit current capacity depends on the number of contacts used and circuit design.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant, meeting European Union Restriction of Hazardous Substances regulations.

Q: Can I mix these connector types in the same design?

A: Yes. Since all three parts are mechanically and electrically equivalent, they can be used interchangeably within the same circuit design without modification to PCB layout or mating connector specifications.
