BSW-118-04-S-D Equivalent & Substitute Parts

Part Overview

The BSW-118-04-S-D is a 36-position rectangular receptacle connector manufactured by Samtec Inc., designed for board-to-board applications with 0.100" (2.54mm) pitch spacing. This connector features a breakaway design with bottom mount through-hole termination and gold-plated mating contacts. The product is currently active in production with 961 units in stock. Equivalent parts are identified when component availability, supply chain considerations, or specific application requirements necessitate alternative sourcing options that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BSW-118-04-S-D is determined by strict alignment of the following critical parameters:

• Connector Configuration: 36-position receptacle with 2-row arrangement
• Pitch Specification: 0.100" (2.54mm) mating pitch and row spacing
• Mounting Interface: Through-hole termination with solder connection
• Contact System: Female socket contacts with gold mating finish at 30.0µin thickness
• Fastening Mechanism: Push-pull fastening type
• Electrical Characteristics: Contact material (Phosphor Bronze), contact shape (Square)

The identified substitute part 1-534267-5 (TE Connectivity AMP Connectors) maintains compatibility across these core parameters. Variations in secondary characteristics such as insulation height, contact post length, and packaging format do not preclude functional equivalence when the primary electrical and mechanical interfaces remain consistent.

Engineering Selection Recommendations

Primary Selection: BSW-118-04-S-D remains the preferred choice for applications requiring ROHS3 compliance and UL94 V-0 flammability certification. This part is actively produced and maintains full regulatory alignment for restricted substance directives.

Substitute Selection: 1-534267-5 provides functional equivalence for applications where RoHS compliance is not mandated. This part is suitable for legacy systems, non-regulated applications, or situations where supply chain continuity requires alternative sourcing. The TE Connectivity AMPMODU Mod IV series maintains electrical and mechanical compatibility through identical pitch, contact configuration, and fastening mechanisms.

Compliance Considerations: Applications subject to RoHS3 requirements must use BSW-118-04-S-D. The substitute part 1-534267-5 is RoHS non-compliant and REACH-affected, making it unsuitable for regulated markets including EU, China, and other regions with equivalent restrictions.

Physical Integration: Differences in insulation height (0.350" vs. 0.265") and contact post length (0.165" vs. 0.125") may affect PCB layout and mating interface clearances. Design verification is necessary when substituting between these parts in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can 1-534267-5 be used as a direct replacement for BSW-118-04-S-D in all applications?

A: Functional compatibility exists for electrical and mechanical mating interfaces. However, regulatory compliance differs significantly. BSW-118-04-S-D is ROHS3 compliant; 1-534267-5 is not. Selection depends on application requirements and regional regulations.

Q: What are the key differences between these connectors?

A: Both connectors share identical 36-position, 0.100" pitch configuration with female socket contacts and gold mating finish. Primary differences include insulation material composition (PET vs. Polyester), insulation height (0.350" vs. 0.265"), contact post length (0.165" vs. 0.125"), and regulatory compliance status (ROHS3 vs. non-compliant).

Q: Does the difference in insulation height affect PCB design?

A: Yes. The BSW-118-04-S-D has 0.350" insulation height compared to 1-534267-5 at 0.265". This 0.085" difference may impact component placement, clearance requirements, and mating interface geometry. PCB layout verification is required when substituting between these parts.

Q: Are the contact post lengths compatible with standard PCB through-hole spacing?

A: Both parts use standard 0.100" (2.54mm) pitch with solder termination. Contact post lengths differ (0.165" vs. 0.125"), which may affect solder joint formation and PCB trace routing. Verify post length compatibility with your PCB design specifications.

Q: What is the significance of the contact finish difference (Tin vs. Tin-Lead)?

A: BSW-118-04-S-D uses tin post finish; 1-534267-5 uses tin-lead finish. Both provide adequate corrosion protection for solder termination. The tin-lead composition in the substitute part reflects older manufacturing standards prior to lead-free transition requirements.

Q: Can these connectors be used interchangeably in legacy systems?

A: Yes, for non-regulated legacy applications. Both connectors maintain identical electrical mating interfaces and push-pull fastening mechanisms. Physical differences in insulation height and contact post length require PCB design compatibility assessment.

Q: What packaging formats are available?

A: BSW-118-04-S-D is supplied in bulk packaging; 1-534267-5 is supplied in tube packaging. Packaging format does not affect connector functionality but may influence inventory management and handling procedures.
