SSQ-150-21-F-D Equivalent & Substitute Parts

Part Overview

The SSQ-150-21-F-D is a 100-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 operating temperatures from -55°C to 125°C. The part is currently active in production with ROHS3 compliance and UL94 V-0 flammability rating. Alternative models within the SSQ series may be required due to inventory availability, specific application requirements, or design revisions that necessitate different contact or fastening configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the SSQ-150 series is determined by strict equivalence across the following critical parameters: connector type (receptacle), number of positions (100), mating pitch (0.100"), row configuration (2 rows), mounting method (through hole), termination type (solder), fastening mechanism (push-pull), contact finish specifications (gold mating, tin post), and electrical ratings (465VAC, 655VDC). The SSQ-150-01-F-D qualifies as a direct substitute because it maintains identical values across all these parameters. Variations in part number suffixes reflect different design revisions or manufacturing batches within the same functional specification, not changes to electrical or mechanical characteristics that would affect interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both SSQ-150-21-F-D and SSQ-150-01-F-D are active production parts with identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and lead time requirements. Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for equivalent applications. The SSQ-150-01-F-D currently has higher inventory availability (1034 pcs vs. 884 pcs), which may influence procurement decisions for high-volume production schedules.

Frequently Asked Questions (FAQ)

Q: Are SSQ-150-21-F-D and SSQ-150-01-F-D mechanically interchangeable?

A: Yes. Both connectors share identical mechanical dimensions, including mating pitch (0.100"), insulation height (0.335"), contact length (0.104"), and row spacing (0.100"). They mount identically in through-hole applications and accept the same mating connectors.

Q: Do these parts have the same electrical ratings?

A: Yes. Both parts are rated for 465VAC and 655VDC with identical operating temperature ranges (-55°C to 125°C). Contact finish specifications are identical: gold plating on mating contacts and tin plating on solder posts.

Q: What determines substitutability within the SSQ-150 series?

A: Substitutability is determined by matching connector type (receptacle), position count (100), mating pitch (0.100"), row configuration (2 rows), mounting method (through hole), termination type (solder), fastening mechanism (push-pull), and electrical ratings. Parts meeting all these criteria are functionally equivalent regardless of part number suffix variations.

Q: Are both parts RoHS compliant?

A: Yes. Both SSQ-150-21-F-D and SSQ-150-01-F-D are ROHS3 compliant and carry UL94 V-0 flammability ratings, meeting current regulatory standards for electronic component manufacturing.

Q: Can I use these connectors in high-temperature applications?

A: Both parts are rated for continuous operation from -55°C to 125°C. Applications requiring operation outside this range require alternative connector designs.
