Engineering Selection Recommendations

All four Samtec MTLW series substitutes provide active product status with ROHS3 compliance, addressing the obsolescence and regulatory limitations of the original 87827-136H. The primary differentiation among substitutes lies in contact length specifications, which directly impact board stack-up depth and mating engagement characteristics.

MTLW-136-06-F-S-125: Shortest mating contact length (0.125") with longest post length (0.115"). Suitable for applications requiring minimal board-to-board separation.

MTLW-136-06-F-S-130: Moderate mating contact length (0.130") with post length of 0.110". Provides balanced engagement characteristics.

MTLW-136-06-F-S-145: Extended mating contact length (0.145") with post length of 0.095". Accommodates deeper board stack-up requirements.

MTLW-136-06-F-S-150: Maximum mating contact length (0.150") with shortest post length (0.090"). Designed for maximum board separation tolerance.

Selection should be based on existing board layout constraints and mating connector specifications. All substitutes maintain equivalent electrical performance with 5.2A per contact current rating and -55°C to 125°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can MTLW series connectors directly replace the 87827-136H in existing designs?

A: Direct replacement depends on board stack-up geometry. While all MTLW variants maintain the same 2.54mm pitch, 36-position configuration, and push-pull fastening, they feature reduced overall contact length (0.300" vs. 0.380") and insulation height (0.060" vs. 0.100"). Verify that mating connector depth and board separation accommodate the selected MTLW variant's contact engagement specifications.

Q: What is the primary advantage of switching to Samtec MTLW substitutes?

A: The MTLW series offers active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The original 87827-136H is obsolete and RoHS non-compliant, creating supply chain and regulatory risk.

Q: How do I select between the four MTLW contact length variants?

A: Contact length selection is determined by your application's board-to-board spacing and mating connector specifications. Measure the depth of the mating connector socket and available board separation to identify the appropriate variant. MTLW-136-06-F-S-125 accommodates the tightest spacing, while MTLW-136-06-F-S-150 supports maximum separation.

Q: Are there electrical performance differences between the 87827-136H and MTLW substitutes?

A: The MTLW series provides specified electrical ratings (5.2A per contact, -55°C to 125°C operating range) not documented for the original part. Both maintain UL94 V-0 flammability rating, phosphor bronze contacts with gold plating, and MSL 1 moisture sensitivity classification.

Q: What is the impact of reduced insulation height in MTLW connectors?

A: The MTLW series features 0.060" insulation height compared to 0.100" in the original part. This reduction affects board stack-up profile and clearance to adjacent components. Verify PCB layout compatibility, particularly for high-density applications with limited vertical clearance.

Q: Are MTLW connectors compatible with existing 87827-136H mating connectors?

A: Compatibility depends on the mating connector design. The 2.54mm pitch and 36-position configuration are identical, but differences in contact length and insulation height may affect engagement depth and mechanical fit. Consult mating connector specifications and conduct physical fit verification before production implementation.
