SSW-125-01-S-D-LL Equivalent & Substitute Parts

Part Overview

The SSW-125-01-S-D-LL is a 50-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 mounting, and push-pull fastening. The part is currently active in production and widely stocked. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, lead time considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSW-125-01-S-D-LL is determined by strict alignment of the following parameters:

• Connector type: Receptacle
• Position count: 50 positions
• Mating pitch: 0.100" (2.54mm)
• Row configuration: 2 rows with 0.100" (2.54mm) spacing
• Mounting method: Through hole
• Fastening mechanism: Push-pull
• Mating contact finish: Gold plating
• Contact material: Phosphor bronze
• Operating temperature compatibility: Minimum -55°C, maximum 125°C

The identified substitute part 2-534206-5 (TE Connectivity AMP Connectors) meets these core electrical and mechanical criteria, enabling direct functional equivalence in applications requiring 50-position rectangular connectors with standard 0.100" pitch spacing.

Parameter Comparison

Engineering Selection Recommendations

Both the SSW-125-01-S-D-LL and 2-534206-5 are active production parts with equivalent core specifications for 50-position rectangular connector applications. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Packaging format preference (bulk versus tube)
• Insulation material compatibility with application environment (LCP versus polyester glass-filled)
• Insulation height tolerance (0.335" versus 0.320")
• Contact post length variation (0.104" versus 0.115")
• Current rating requirements (4.7A per contact versus 2A per contact)
• Temperature range margin (lower limit -55°C versus -65°C)
• RoHS compliance status (ROHS3 compliant versus not applicable)

Both parts carry EAR99 export classification and share identical HTSUS coding, supporting equivalent regulatory treatment in procurement workflows.

Frequently Asked Questions (FAQ)

Q: Can the 2-534206-5 directly replace the SSW-125-01-S-D-LL in existing designs?

A: Direct mechanical and electrical substitution is supported for applications requiring 50-position receptacle connectors with 0.100" pitch and push-pull fastening. Physical differences in insulation height and contact post length must be verified against PCB layout constraints and mating plug specifications.

Q: What are the key differences between these two connectors?

A: The primary differences are insulation material composition (LCP versus polyester glass-filled), insulation height (0.335" versus 0.320"), contact post length (0.104" versus 0.115"), current rating per contact (4.7A versus 2A), and operating temperature lower limit (-55°C versus -65°C). Mating pitch, position count, and contact finish specifications are identical.

Q: Does packaging format affect connector performance?

A: Packaging format (bulk versus tube) does not affect electrical or mechanical performance. Selection should be based on assembly process requirements and inventory management practices.

Q: Are there compliance or certification differences?

A: The SSW-125-01-S-D-LL is ROHS3 compliant. The 2-534206-5 is not RoHS applicable. Both parts carry identical ECCN and HTSUS classifications. Compliance requirements for the target application must be verified before selection.

Q: Which connector should be selected for high-current applications?

A: The SSW-125-01-S-D-LL supports 4.7A per contact, while the 2-534206-5 supports 2A per contact. Applications requiring current ratings above 2A per contact must use the SSW-125-01-S-D-LL.
