SSQ-106-21-F-S Equivalent & Substitute Parts

Part Overview

The SSQ-106-21-F-S is a 6-position receptacle connector manufactured by Samtec Inc., designed for board-to-board or cable applications with 0.100" (2.54mm) pitch through-hole mounting. This connector features gold-plated mating contacts, tin-plated posts, and is rated for -55°C to 125°C operation with UL94 V-0 flammability compliance. The part is currently active in production with 912 units in stock. Substitute parts are identified when electrical and mechanical parameters remain identical, ensuring direct functional equivalence for component selection and inventory management.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSQ-106-21-F-S is determined by strict equivalence across the following critical parameters:

• Connector Configuration: Receptacle type with 6 positions at 0.100" (2.54mm) pitch
• Electrical Ratings: 465VAC and 655VDC voltage specifications
• Contact Materials and Finishes: Gold mating surface (3.00µin thickness) and tin post finish
• Mechanical Specifications: Through-hole solder termination with push-pull fastening
• Environmental Compliance: UL94 V-0 flammability rating and ROHS3 compliance
• Operating Conditions: -55°C to 125°C temperature range

The substitute part SSQ-106-01-F-S meets all these criteria, differing only in moisture sensitivity level classification and REACH status documentation, which do not affect functional or electrical equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both SSQ-106-21-F-S and SSQ-106-01-F-S are active production parts from Samtec Inc. with full ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and lead time requirements. The SSQ-106-01-F-S currently maintains higher stock levels (1567 units versus 912 units), making it suitable for applications where immediate availability is prioritized. Both parts satisfy identical design requirements for 6-position, 0.100" pitch through-hole receptacle applications with gold mating contacts and tin-plated posts across the full -55°C to 125°C operating range.

Frequently Asked Questions (FAQ)

Q: Can SSQ-106-01-F-S be used as a direct replacement for SSQ-106-21-F-S?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters, including connector configuration, contact materials, finishes, voltage ratings, temperature range, and flammability compliance. Direct substitution is supported without design modification.

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

A: Substitution is valid when the following parameters match: connector type (receptacle), number of positions (6), pitch (0.100"), mounting method (through-hole), contact finishes (gold mating, tin post), voltage ratings (465VAC/655VDC), operating temperature (-55°C to 125°C), and flammability rating (UL94 V-0).

Q: Are there differences in moisture sensitivity between these parts?

A: The SSQ-106-21-F-S lists moisture sensitivity as not applicable, while SSQ-106-01-F-S is classified as MSL 1 (Unlimited). This classification difference does not affect electrical or mechanical performance and does not impact substitution eligibility.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both parts are ROHS3 compliant, carry EAR99 ECCN classification, and share identical HTSUS codes (8536.69.4040). Both maintain active production status with UL94 V-0 flammability certification.

Q: What should guide the selection between these two equivalent parts?

A: Selection should be based on inventory availability and procurement lead times. The SSQ-106-01-F-S has higher current stock (1567 units), while the SSQ-106-21-F-S has 912 units available. Both are functionally identical for design purposes.
