SSQ-120-23-F-S Equivalent & Substitute Parts

Part Overview

The SSQ-120-23-F-S is a 20-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 push-pull fastening. The product is active and ROHS3 compliant, making it suitable for industrial and commercial applications requiring reliable interconnection in temperature ranges from -55°C to 125°C. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector series.

Key Parameters

Substitute Part Grouping Explanation

The SSQ-120-03-F-S qualifies as a direct substitute for the SSQ-120-23-F-S based on the following critical parameters:

• Connector Type & Configuration: Both are 20-position receptacle connectors with identical pitch (0.100"), mounting method (through hole), and fastening mechanism (push-pull)
• Contact Specifications: Matching gold mating contact finish (3.00µin thickness), tin post finish, forked contact type, and square contact shape
• Electrical & Environmental Ratings: Identical voltage ratings (465VAC, 655VDC), operating temperature range (-55°C ~ 125°C), and UL94 V-0 flammability rating
• Material & Compliance: Both use Liquid Crystal Polymer (LCP) insulation and maintain ROHS3 compliance
• Series Alignment: Both parts belong to the SSQ series with matching base product number (SSQ-120)

The substitution is valid across all standard interconnection applications where these electrical and mechanical parameters are required.

Parameter Comparison

Engineering Selection Recommendations

Both the SSQ-120-23-F-S and SSQ-120-03-F-S are active products from Samtec Inc. with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on inventory availability and lead time requirements, as all electrical, mechanical, and environmental specifications are identical. The SSQ-120-23-F-S currently maintains higher inventory (1003 pcs), while the SSQ-120-03-F-S provides an alternative source (789 pcs). Both parts carry EAR99 export classification and are suitable for applications requiring 465VAC/655VDC rated interconnection in industrial temperature environments.

Frequently Asked Questions (FAQ)

Q: Are SSQ-120-23-F-S and SSQ-120-03-F-S fully interchangeable?

A: Yes. Both connectors share identical electrical ratings (465VAC, 655VDC), mechanical configuration (20-position, 0.100" pitch, through-hole), contact specifications (gold mating, tin post), and environmental certifications (UL94 V-0, ROHS3). They are direct substitutes within the SSQ series.

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

A: Substitution is valid when the following parameters match: connector type (receptacle), number of positions (20), mating pitch (0.100"), mounting method (through hole), fastening type (push-pull), contact finishes (gold/tin), operating temperature range (-55°C to 125°C), and voltage ratings (465VAC, 655VDC).

Q: Do these connectors require different PCB footprints?

A: No. Both parts maintain identical mechanical dimensions, including insulation height (0.335"), contact post length (0.394"), and pitch spacing. PCB layouts are compatible.

Q: Are there differences in moisture sensitivity or storage requirements?

A: The SSQ-120-03-F-S specifies Moisture Sensitivity Level 1 (Unlimited), while the SSQ-120-23-F-S lists MSL as Not Applicable. Both are suitable for standard storage and handling conditions without special moisture control requirements.

Q: Can these connectors be used in high-temperature applications?

A: Yes. Both connectors are rated for continuous operation from -55°C to 125°C and feature UL94 V-0 rated insulation material (Liquid Crystal Polymer), making them suitable for industrial temperature environments.
