SSQ-108-02-S-S Equivalent & Substitute Parts

Part Overview

The SSQ-108-02-S-S is an 8-position receptacle connector manufactured by Samtec Inc., designed for board-to-board or cable applications with 0.100" (2.54mm) pitch spacing. This connector features gold-plated mating contacts, through-hole solder termination, and push-pull fastening. The part is currently active in production with 831 units in stock. Alternative equivalent parts may be required due to supply constraints, design revisions, or specific application requirements where substitute connectors meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The 3M 929850-01-08-RB qualifies as an equivalent substitute for the SSQ-108-02-S-S based on the following critical parameters:

• 8-position receptacle configuration with identical connector type and contact arrangement
• 0.100" (2.54mm) pitch spacing for direct mechanical compatibility
• Forked contact type with square contact geometry
• Through-hole solder termination and push-pull fastening mechanism
• Gold-plated mating contacts at 30.0µin (0.76µm) thickness
• Both parts are active products with RoHS compliance and MSL 1 rating

Substitution is valid where the specified parameters align between the main part and substitute. Differences in insulation material, operating temperature range, and contact post specifications do not preclude substitution when application requirements fall within the overlapping operational envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the SSQ-108-02-S-S and 929850-01-08-RB are active products with equivalent core connector specifications. Selection between these parts should be based on:

• Operating temperature requirements: The SSQ-108-02-S-S supports -55°C to 125°C, while the 929850-01-08-RB operates from -40°C to 105°C. Applications requiring extended low-temperature operation below -40°C necessitate the Samtec part.
• Voltage rating: The 3M substitute provides 1500V rating compared to the Samtec part's 655VDC maximum. Applications with higher voltage requirements favor the 929850-01-08-RB.
• Current capacity: The 3M part specifies 2A current rating; the Samtec part does not provide this specification.
• Insulation material: The SSQ-108-02-S-S uses Liquid Crystal Polymer (LCP), while the 929850-01-08-RB uses Polycyclohexylenedimethylene Terephthalate (PCT) with glass filler. Material selection depends on specific environmental and mechanical requirements.
• Contact post length: The SSQ-108-02-S-S provides 0.194" (4.93mm) post length versus 0.125" (3.18mm) for the 3M part. PCB thickness and stack-up considerations may influence this selection.

Both parts maintain RoHS compliance and MSL 1 rating, suitable for standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can the 929850-01-08-RB directly replace the SSQ-108-02-S-S in existing designs?

A: Direct replacement is possible when application requirements fall within the overlapping specifications. The 0.100" pitch, 8-position configuration, gold-plated contacts, and push-pull fastening are identical. However, differences in contact post length (0.194" vs. 0.125"), insulation height (0.335" vs. 0.325"), and operating temperature range (-55°C to 125°C vs. -40°C to 105°C) must be evaluated against specific PCB design and thermal requirements.

Q: What are the critical compatibility parameters for these rectangular connectors?

A: Substitution compatibility is determined by: connector type (receptacle), number of positions (8), mating pitch (0.100"), contact type (forked), mounting method (through-hole), termination (solder), fastening mechanism (push-pull), and mating contact finish (gold at 30.0µin). These parameters ensure mechanical and electrical interchangeability.

Q: How do the insulation materials differ between these parts?

A: The SSQ-108-02-S-S uses Liquid Crystal Polymer (LCP), while the 929850-01-08-RB uses Polycyclohexylenedimethylene Terephthalate (PCT) with glass filler. Both materials achieve UL94 V-0 flammability rating. Material selection depends on thermal cycling requirements, chemical resistance, and mechanical stress conditions in the application environment.

Q: Are there differences in contact post specifications that affect PCB design?

A: Yes. The SSQ-108-02-S-S provides 0.194" (4.93mm) contact post length, while the 929850-01-08-RB provides 0.125" (3.18mm). This difference affects PCB thickness compatibility and through-hole depth requirements. Designs with thicker PCBs or specific stack-up configurations may require the longer post length of the Samtec connector.

Q: What voltage and current ratings apply to each connector?

A: The SSQ-108-02-S-S is rated for 465VAC and 655VDC with unspecified current capacity. The 929850-01-08-RB is rated for 1500V with 2A current capacity. Applications requiring higher voltage operation favor the 3M part, while current requirements must be confirmed against the Samtec specification sheet.

Q: Do both connectors meet RoHS and moisture sensitivity requirements?

A: Yes. Both the SSQ-108-02-S-S (ROHS3 Compliant) and 929850-01-08-RB (RoHS Compliant) meet RoHS standards. Both carry MSL 1 (Unlimited) moisture sensitivity level, indicating no special storage or handling requirements for standard manufacturing environments.
