SSQ-109-23-S-D Equivalent & Substitute Parts

Part Overview

The SSQ-109-23-S-D is an 18-position receptacle connector manufactured by Samtec Inc., designed for board-to-board or cable applications with 0.100" (2.54mm) pitch spacing. This through-hole connector features gold-plated mating contacts and tin-plated posts, operating across -55°C to 125°C with UL94 V-0 flammability rating. The part is currently active in production with 715 units in stock. Substitute parts are identified when electrical and mechanical parameters align within the SSQ series specifications, enabling direct functional replacement in applications where connector footprint and contact configuration remain constant.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the SSQ-109 series is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Receptacle, 18 positions, 2 rows, forked contact type
• Pitch Specifications: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Termination: Through-hole solder termination with push-pull fastening
• Contact Materials & Finish: Gold-plated mating contacts (30.0µin thickness) and tin-plated posts
• Electrical Ratings: 465VAC / 655VDC voltage rating
• Environmental Compliance: UL94 V-0 flammability, ROHS3 compliance, operating range -55°C to 125°C
• Insulation Material: Liquid Crystal Polymer (LCP)

The SSQ-109-03-S-D meets all these criteria and is classified as a direct substitute for the SSQ-109-23-S-D within the same product series.

Parameter Comparison

Engineering Selection Recommendations

Both SSQ-109-23-S-D and SSQ-109-03-S-D are active production parts from Samtec Inc. with identical electrical, mechanical, and environmental specifications. Selection between these parts is based on inventory availability and supply chain considerations rather than functional differences. Both parts carry ROHS3 compliance and UL94 V-0 flammability certification, meeting equivalent regulatory requirements for industrial and commercial applications. The SSQ-109-03-S-D currently maintains higher inventory (749 units) compared to SSQ-109-23-S-D (715 units), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Are SSQ-109-23-S-D and SSQ-109-03-S-D electrically interchangeable?

A: Yes. Both connectors share identical electrical ratings (465VAC / 655VDC), operating temperature range (-55°C to 125°C), and contact materials (phosphor bronze with gold mating finish and tin post finish). They are direct electrical equivalents.

Q: Do these connectors have the same physical footprint?

A: Yes. Both parts feature identical mechanical specifications: 18 positions in a 2-row configuration with 0.100" (2.54mm) pitch spacing, 0.335" (8.51mm) insulation height, and 0.394" (10.00mm) contact post length. PCB layout compatibility is maintained.

Q: What is the difference between SSQ-109-23-S-D and SSQ-109-03-S-D?

A: The provided specifications indicate these parts are functionally equivalent within the SSQ-109 series. Differences, if any, are not reflected in the documented electrical, mechanical, or environmental parameters.

Q: Are both parts RoHS compliant?

A: Yes. Both SSQ-109-23-S-D and SSQ-109-03-S-D are ROHS3 compliant and carry UL94 V-0 flammability certification.

Q: Can I use SSQ-109-03-S-D as a direct replacement in existing designs?

A: Yes. The SSQ-109-03-S-D is a direct substitute for SSQ-109-23-S-D. No design modifications are required for PCB layout, schematic, or assembly processes.

Q: What is the moisture sensitivity level for these connectors?

A: SSQ-109-23-S-D is not subject to moisture sensitivity level classification. SSQ-109-03-S-D carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
