SSQ-110-21-S-S Equivalent & Substitute Parts

Part Overview

The SSQ-110-21-S-S is a 10-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 part is currently active in production with 883 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part becomes unavailable or when design requirements permit alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

The 929850-01-10-RB (3M) qualifies as a substitute for the SSQ-110-21-S-S based on the following alignment of critical parameters:

• Connector Type & Position Count: Both are 10-position receptacle connectors
• Pitch Specification: Both maintain 0.100" (2.54mm) mating pitch
• Mounting & Termination: Both use through-hole solder termination
• Contact Configuration: Both feature forked contacts with gold mating finish and tin post finish
• Fastening Mechanism: Both employ push-pull fastening
• Flammability Compliance: Both meet UL94 V-0 material rating
• Row Configuration: Both are single-row designs

Substitution is valid where these core electrical and mechanical parameters are required. Differences in operating temperature range, voltage rating, current rating, insulation height, contact post length, and insulation material composition exist between the parts and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the SSQ-110-21-S-S and 929850-01-10-RB are active production parts with established compliance certifications. Selection between these parts should be based on application-specific requirements:

SSQ-110-21-S-S (Samtec) is suitable for applications requiring extended operating temperature range (-55°C to 125°C) and lower voltage specifications (465VAC, 655VDC). The LCP insulation material and phosphor bronze contacts provide specific material properties for defined thermal and electrical environments.

929850-01-10-RB (3M) is suitable for applications requiring higher voltage tolerance (1500V) and specified current rating (2A). The extended contact post length (0.125" vs 0.104") and higher insulation height tolerance may be relevant for specific PCB layout requirements. The operating temperature range (-40°C to 105°C) is narrower than the Samtec equivalent.

Both parts meet UL94 V-0 flammability requirements and share identical mating pitch, position count, and fastening mechanisms. Mechanical fit verification is necessary due to differences in insulation height and contact post length, which may affect PCB hole sizing and board-to-board spacing.

Frequently Asked Questions (FAQ)

Q: Can the 929850-01-10-RB directly replace the SSQ-110-21-S-S in all applications?

A: Direct replacement is valid only when the application requirements fall within the operating parameters of both parts. The 929850-01-10-RB has a narrower operating temperature range (-40°C to 105°C versus -55°C to 125°C) and different insulation height (0.325" versus 0.335"). PCB hole sizing and board-to-board spacing must be verified due to the 0.021" difference in contact post length.

Q: What are the key electrical differences between these parts?

A: The 929850-01-10-RB specifies a 2A current rating and 1500V voltage rating, while the SSQ-110-21-S-S specifies 465VAC and 655VDC without a stated current rating. Applications requiring the 2A current specification or 1500V voltage tolerance must use the 3M part.

Q: Are both parts RoHS compliant?

A: Yes. The SSQ-110-21-S-S is ROHS3 Compliant, and the 929850-01-10-RB is RoHS Compliant. Both meet regulatory requirements for restricted substance elimination.

Q: What insulation materials are used in each connector?

A: The SSQ-110-21-S-S uses Liquid Crystal Polymer (LCP), while the 929850-01-10-RB uses Polycyclohexylenedimethylene Terephthalate (PCT) with polyester and glass filling. Material selection affects thermal performance and mechanical properties in specific operating environments.

Q: How do the contact materials differ?

A: The SSQ-110-21-S-S uses phosphor bronze contacts, while the 929850-01-10-RB uses copper alloy contacts. Both are tin-plated on the post and gold-plated on the mating surface with identical 30.0µin (0.76µm) gold thickness.

Q: Are there packaging or inventory considerations?

A: The SSQ-110-21-S-S has 883 units in stock, while the 929850-01-10-RB has 1072 units in stock. Both are supplied in bulk packaging.
