SSW-120-01-S-S Equivalent & Substitute Parts

Part Overview

The SSW-120-01-S-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, forked contact geometry, and push-pull fastening. The part is currently active in production with 906 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's specifications, enabling direct replacement in applications where the core functional requirements remain constant.

Substitute Part Grouping Explanation

Substitution eligibility for the SSW-120-01-S-S is determined by the following critical parameters:

Connector Type & Position Count: All substitute parts must be 20-position receptacle connectors
Pitch Specification: Mating pitch must be 0.100" (2.54mm) to ensure mechanical and electrical compatibility
Mounting & Termination: Through-hole solder termination is required for PCB integration
Fastening Mechanism: Push-pull fastening type must be maintained for consistent mating/unmating operation
Contact Finish: Gold plating on mating contacts with 30.0µin (0.76µm) thickness ensures signal integrity and corrosion resistance
Insulation Material & Color: Black insulation is standard across all identified substitutes

The three substitute parts—1-534237-8, 6-534237-8, and 929850-01-20-RB—meet these core requirements and are classified as equivalent alternatives.

Engineering Selection Recommendations

Primary Substitute: 6-534237-8 (TE Connectivity)

The 6-534237-8 is the preferred substitute for the SSW-120-01-S-S. This part maintains full compliance with RoHS3 standards, matching the regulatory status of the main part. It carries UL94 V-0 flammability certification and is actively produced with 1,738 units in inventory. The operating temperature range of -65°C to 125°C exceeds the main part's -55°C to 125°C specification, providing extended low-temperature capability.

Secondary Substitute: 929850-01-20-RB (3M)

The 929850-01-20-RB is a compliant alternative with RoHS certification and UL94 V-0 flammability rating. This part is suitable for applications where the operating temperature range of -40°C to 105°C is acceptable. The 1,500V voltage rating specification provides additional electrical performance data not listed for the main part. Inventory availability is 1,187 units.

Non-Recommended: 1-534237-8 (TE Connectivity)

The 1-534237-8 does not meet current RoHS compliance requirements and is classified as RoHS non-compliant. This part is not suitable for new designs or applications requiring regulatory compliance with RoHS3 standards.

Frequently Asked Questions (FAQ)

Q: Can the 6-534237-8 directly replace the SSW-120-01-S-S in existing designs?

A: Yes. Both parts share identical mating pitch (0.100"), position count (20), contact finish (gold, 30.0µin), mounting type (through-hole), and fastening mechanism (push-pull). The 6-534237-8 maintains RoHS3 compliance and UL94 V-0 certification. The extended operating temperature range (-65°C to 125°C) is compatible with applications designed for the SSW-120-01-S-S.

Q: What is the primary difference between the two TE Connectivity substitutes?

A: The 6-534237-8 is RoHS3 compliant with UL94 V-0 certification, while the 1-534237-8 is RoHS non-compliant. For new designs and regulated applications, the 6-534237-8 is the appropriate choice.

Q: Why is the current rating different between the main part and substitutes?

A: The SSW-120-01-S-S is rated at 4.7A per contact, while the substitute parts are rated at 2A per contact. Applications requiring the higher current capacity of the main part should not use these substitutes. Verify current requirements before selection.

Q: Are there packaging differences between these parts?

A: Yes. The SSW-120-01-S-S is supplied in bulk packaging, while the TE Connectivity substitutes (1-534237-8 and 6-534237-8) are supplied in tube packaging. The 3M substitute (929850-01-20-RB) is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Which substitute offers the widest operating temperature range?

A: Both TE Connectivity parts (1-534237-8 and 6-534237-8) operate from -65°C to 125°C, exceeding the main part's -55°C to 125°C range. The 3M substitute operates from -40°C to 105°C, which is narrower than the main part specification.
