SSQ-118-01-G-S Equivalent & Substitute Parts

Part Overview

The SSQ-118-01-G-S is an 18-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, push-pull fastening, and operates across -55°C to 125°C. The part is currently active in production with 652 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability for procurement flexibility or inventory optimization.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 6-534237-6 (TE Connectivity AMP Connectors) qualifies as an equivalent based on the following critical parameters:

• Connector Type & Position Count: Both are 18-position receptacles
• Pitch & Mounting: Identical 0.100" (2.54mm) pitch with through-hole solder termination
• Fastening & Contact Finish: Both employ push-pull fastening with gold-plated mating contacts
• Electrical Compliance: Both meet UL94 V-0 flammability and RoHS requirements
• Operating Range: Substitute operates -65°C ~ 125°C, encompassing the original -55°C ~ 125°C range

Substitution is valid where these core parameters align. Differences in insulation material (LCP vs. Polyester, Glass Filled), contact finish thickness, and post contact material do not preclude functional equivalence in standard board-to-board or cable connector applications.

Parameter Comparison

Engineering Selection Recommendations

Both the SSQ-118-01-G-S and 6-534237-6 are active production parts with equivalent functional specifications for 18-position, 0.100" pitch rectangular connector applications. Selection between these parts should be based on:

• Inventory Availability: SSQ-118-01-G-S has 652 units in stock (Bulk packaging); 6-534237-6 has 1657 units in stock (Tube packaging)
• Compliance Status: SSQ-118-01-G-S is ROHS3 Compliant; 6-534237-6 is RoHS Compliant. Both meet UL94 V-0 flammability requirements
• Packaging Format: Bulk vs. Tube packaging may influence procurement and handling procedures
• Temperature Operating Range: 6-534237-6 extends to -65°C, providing broader low-temperature coverage than the original -55°C minimum

Frequently Asked Questions (FAQ)

Q: Can 6-534237-6 directly replace SSQ-118-01-G-S in existing designs?

A: Yes, where the core parameters align: 18-position receptacle, 0.100" pitch, through-hole solder termination, push-pull fastening, and gold mating contacts. Both connectors are mechanically and electrically compatible for board-to-board and cable applications.

Q: What are the differences in insulation material between these parts?

A: SSQ-118-01-G-S uses Liquid Crystal Polymer (LCP); 6-534237-6 uses Polyester, Glass Filled. Both materials meet UL94 V-0 flammability requirements. Material selection does not affect connector interchangeability in standard applications.

Q: Does the operating temperature difference matter?

A: The 6-534237-6 operates from -65°C to 125°C, while SSQ-118-01-G-S operates from -55°C to 125°C. The substitute part provides extended low-temperature capability. For applications within the original -55°C to 125°C range, both parts are functionally equivalent.

Q: What is the significance of packaging differences (Bulk vs. Tube)?

A: Bulk packaging typically suits high-volume manufacturing environments, while Tube packaging is standard for component distribution and smaller-quantity orders. Packaging does not affect connector performance or compatibility.

Q: Are both parts RoHS compliant?

A: Yes. SSQ-118-01-G-S is ROHS3 Compliant; 6-534237-6 is RoHS Compliant. Both meet regulatory requirements for lead-free and restricted substance compliance.
