Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSQ-108-21-L-S is determined by strict equivalence across the following critical parameters:

• Connector configuration: 8-position receptacle with 0.100" (2.54mm) pitch
• Mounting and termination: Through-hole solder termination
• Contact specifications: Gold mating finish (10.0µin thickness), tin post finish, forked contact type, square contact shape
• Electrical ratings: 465VAC / 655VDC voltage rating
• Environmental compliance: UL94 V-0 flammability rating, ROHS3 compliance
• Operating range: -55°C to 125°C temperature rating

The SSQ-108-01-L-S meets all these criteria and is classified as a direct substitute within the SSQ series family.

Parameter Comparison

Engineering Selection Recommendations

Both SSQ-108-21-L-S and SSQ-108-01-L-S are active production parts with full ROHS3 compliance and UL94 V-0 material certification. Selection between these parts may be based on inventory availability: SSQ-108-21-L-S has 679 units in stock, while SSQ-108-01-L-S has 963 units in stock. Both parts carry identical electrical specifications, mechanical dimensions, and environmental ratings, making them functionally interchangeable for applications requiring 8-position 0.100" pitch receptacle connectors with gold mating contacts and tin-plated posts.

Frequently Asked Questions (FAQ)

Q: Can SSQ-108-01-L-S be used as a direct replacement for SSQ-108-21-L-S?

A: Yes. Both parts are identical in all critical parameters including connector type, position count, pitch, contact finishes, voltage rating, temperature range, and compliance certifications. No design modification is required.

Q: What determines substitution eligibility for SSQ series receptacle connectors?

A: Substitution requires matching connector type (receptacle), position count (8), mating pitch (0.100"), contact finishes (gold mating / tin post), voltage rating (465VAC / 655VDC), operating temperature range (-55°C to 125°C), and compliance status (UL94 V-0, ROHS3).

Q: Are there differences in contact material or geometry between these parts?

A: No. Both parts use phosphor bronze contacts with square geometry and forked contact type. Contact finish specifications are identical.

Q: How do these parts differ from other SSQ series connectors?

A: The SSQ-108-21-L-S and SSQ-108-01-L-S are distinguished by their specific contact finish combinations and internal design variations within the SSQ-108 base product family. Other SSQ series variants may differ in position count, pitch, or contact configurations.

Q: What is the significance of the base product number SSQ-108?

A: The base product number SSQ-108 identifies the core connector family. The suffix designations (-21-L-S and -01-L-S) indicate specific variants within this family that maintain electrical and mechanical compatibility.
