Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSQ-120-23-F-D-RA is determined by strict alignment of the following critical parameters:

• Connector Type & Position Count: Receptacle configuration with 40 positions
• Pitch & Row Configuration: 0.100" (2.54mm) mating pitch with 2-row layout
• Mounting & Termination: Through-hole, right-angle mounting with solder termination
• Contact System: Forked contact type with gold mating finish and tin post finish
• Electrical Ratings: 465VAC and 655VDC voltage compatibility
• Environmental Compliance: UL94 V-0 flammability rating and ROHS3 compliance
• Operating Temperature: -55°C to 125°C range

The substitute part SSQ-120-03-F-D-RA shares all critical electrical, mechanical, and environmental parameters with the main part, differing only in moisture sensitivity level classification, which does not affect functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both the SSQ-120-23-F-D-RA and SSQ-120-03-F-D-RA are active products from Samtec Inc. with full ROHS3 compliance and UL94 V-0 flammability certification. The parts are electrically and mechanically interchangeable across all specified parameters. Selection between these parts should be based on supply chain availability and inventory status. The SSQ-120-03-F-D-RA currently maintains higher inventory levels (897 pcs vs. 646 pcs), making it a viable alternative for procurement planning. Both parts meet identical environmental and electrical performance requirements for applications requiring 40-position, 0.100" pitch rectangular connectors with right-angle through-hole mounting.

Frequently Asked Questions (FAQ)

Q: Are SSQ-120-23-F-D-RA and SSQ-120-03-F-D-RA pin-compatible?

A: Yes. Both connectors feature identical 40-position configurations with 0.100" (2.54mm) mating pitch and 2-row layout. Pin-to-pin compatibility is complete.

Q: What is the difference between these two part numbers?

A: The primary difference is the moisture sensitivity level (MSL) classification. SSQ-120-23-F-D-RA is classified as Not Applicable, while SSQ-120-03-F-D-RA is classified as MSL 1 (Unlimited). This distinction does not affect electrical or mechanical performance in standard applications.

Q: Can I substitute SSQ-120-03-F-D-RA for SSQ-120-23-F-D-RA in my design?

A: Yes. Both parts share identical electrical ratings (465VAC, 655VDC), operating temperature range (-55°C to 125°C), contact finishes, and mechanical mounting specifications. Substitution is functionally equivalent.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and carry UL94 V-0 flammability certification. Compliance requirements are identical.

Q: What mounting configuration do these connectors use?

A: Both connectors use through-hole, right-angle mounting with solder termination, suitable for PCB integration in board-to-board or cable applications.

Q: Are the contact finishes identical?

A: Yes. Both parts feature gold-plated mating contacts (3.00µin thickness) and tin-plated posts, ensuring consistent electrical performance and contact reliability.
