Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSQ-103-21-G-S is determined by strict equivalence across the following critical parameters:

• Manufacturer and series consistency (Samtec Inc., SSQ series)
• Connector type and contact configuration (Receptacle, forked contacts)
• Electrical specifications (3 positions, 0.100" pitch, 465VAC/655VDC voltage rating)
• Mechanical interface (Through-hole solder termination, push-pull fastening)
• Environmental compliance (Operating temperature -55°C ~ 125°C, UL94 V-0, ROHS3 Compliant)
• Contact material and finish (Phosphor bronze with gold plating, 20.0µin mating finish)

The substitute part SSQ-103-01-G-S meets all these criteria, maintaining identical electrical performance, mechanical compatibility, and regulatory compliance. Both parts share the same base product number (SSQ-103) and differ only in internal design variants that do not affect functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both SSQ-103-21-G-S and SSQ-103-01-G-S are active production parts from Samtec Inc. with identical ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on inventory availability and procurement lead times. The SSQ-103-01-G-S currently maintains higher stock levels (3811 units) compared to SSQ-103-21-G-S (992 units), making it the preferred choice for applications requiring immediate availability. Both parts satisfy equivalent electrical and mechanical requirements for standard board-to-board and cable connector applications within the specified operating temperature and voltage ranges.

Frequently Asked Questions (FAQ)

Q: Can SSQ-103-01-G-S be used as a direct replacement for SSQ-103-21-G-S?

A: Yes. Both parts are functionally equivalent receptacle connectors with identical electrical ratings (465VAC/655VDC), mechanical specifications (3 positions, 0.100" pitch, through-hole solder termination), and environmental compliance (UL94 V-0, ROHS3). They share the same base product number and contact configuration.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is valid when the following parameters match: connector type (receptacle), number of positions (3), mating pitch (0.100"), mounting method (through-hole), termination type (solder), voltage rating (465VAC/655VDC), operating temperature range (-55°C ~ 125°C), contact material and finish (phosphor bronze with gold plating), and regulatory compliance (ROHS3, UL94 V-0).

Q: Are there any differences in package or handling between these parts?

A: Both parts are supplied in bulk packaging. No differences in moisture sensitivity level (not applicable) or handling requirements exist between SSQ-103-21-G-S and SSQ-103-01-G-S.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should prioritize the part with better supply chain availability. Currently, SSQ-103-01-G-S has higher inventory levels and may offer shorter lead times.
