SSQ-111-01-F-S Equivalent & Substitute Parts

Part Overview

The SSQ-111-01-F-S is an 11-position rectangular 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 and tin-plated posts, operating across -55°C to 125°C with UL94 V-0 flammability rating and ROHS3 compliance. Finding equivalent or substitute parts may be necessary due to inventory availability, lead time requirements, or specific contact finish specifications for particular applications.

Key Parameters

Substitute Part Grouping Explanation

The SSQ-111-01-G-S qualifies as a direct substitute for the SSQ-111-01-F-S based on the following critical parameters:

• Identical connector type, position count, and pitch specification
• Matching mounting method (through hole) and fastening mechanism (push-pull)
• Identical contact type (forked) and contact shape (square)
• Same insulation material (Liquid Crystal Polymer), color (black), and height
• Equivalent operating temperature range and voltage ratings
• Identical series designation (SSQ) and base product number (SSQ-111)
• Both parts maintain UL94 V-0 flammability rating and ROHS3 compliance

The primary difference between these parts lies in the contact finish specifications: the SSQ-111-01-F-S features tin-plated posts with 3.00µin gold mating contact finish, while the SSQ-111-01-G-S features gold-plated posts with 20.0µin gold mating contact finish.

Parameter Comparison

Engineering Selection Recommendations

Both the SSQ-111-01-F-S and SSQ-111-01-G-S are active products with full ROHS3 compliance and UL94 V-0 certification. Selection between these parts should be based on contact finish requirements specific to the application. The SSQ-111-01-G-S offers increased gold plating thickness on mating contacts (20.0µin versus 3.00µin) and gold-plated posts, providing enhanced corrosion resistance and contact durability in demanding environments. The SSQ-111-01-F-S with tin-plated posts and minimal gold mating finish is suitable for standard applications where cost optimization is a consideration. Both parts maintain identical mechanical and electrical specifications, ensuring direct interchangeability from a form-fit-function perspective.

Frequently Asked Questions (FAQ)

Q: Are SSQ-111-01-F-S and SSQ-111-01-G-S mechanically interchangeable?

A: Yes. Both connectors share identical mechanical dimensions, mounting specifications, and contact geometry. They can be used interchangeably in applications where the contact finish specifications are compatible.

Q: What is the significance of the contact finish difference?

A: The SSQ-111-01-G-S features thicker gold plating on mating contacts (20.0µin versus 3.00µin) and gold-plated posts instead of tin. This provides superior corrosion resistance and contact reliability in high-humidity, high-temperature, or corrosive environments.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SSQ-111-01-F-S and SSQ-111-01-G-S are ROHS3 compliant, UL94 V-0 rated, and carry EAR99 ECCN classification with identical HTSUS codes.

Q: Can I substitute SSQ-111-01-F-S with SSQ-111-01-G-S in existing designs?

A: Yes, from an electrical and mechanical standpoint. The enhanced contact finish of the SSQ-111-01-G-S is compatible with all mating connectors designed for the SSQ series 11-position 0.100" pitch receptacle.

Q: What is the difference in post finish and why does it matter?

A: The SSQ-111-01-F-S has tin-plated posts while the SSQ-111-01-G-S has gold-plated posts. Gold plating provides better solderability and long-term reliability on PCB assemblies, particularly in applications subject to thermal cycling or extended storage.
