95157-140TLF Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 95157-140TLF is a surface mount rectangular connector header with 40 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This BERGSTIK® II series connector is designed for board-to-board applications with male pin contacts, gold-plated mating surfaces, and solder termination. The part is active in production with full position loading and operates across -65°C to 130°C.

Substitute parts are necessary when original inventory is unavailable, when packaging requirements differ (tube versus tape & reel), or when design flexibility permits alternative contact finishes or insulation materials that maintain electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All four Samtec TSM-120 series variants are electrically and mechanically compatible with the 95157-140TLF based on matching critical dimensional and contact parameters. Selection among substitutes depends on specific application requirements:

TSM-120-01-L-DV-A-P-TR — Select this variant for automated assembly processes requiring tape & reel packaging with pick-and-place compatibility. The board guide feature provides mechanical alignment during placement. Gold contact finish with 10.0µin thickness meets corrosion resistance requirements. Operating temperature range of -55°C to 125°C is suitable for standard industrial and commercial applications.

TSM-120-01-S-DV — Select this variant when tube packaging is required and manual assembly or lower-volume production is planned. Gold contact finish with 30.0µin thickness matches the original part specification. Operating temperature range of -55°C to 125°C covers standard industrial applications.

TSM-120-01-S-DV-P-TR — Select this variant for automated assembly with tape & reel packaging when pick-and-place features are required. Gold contact finish with 30.0µin thickness provides enhanced durability. Tube packaging alternative (TSM-120-01-S-DV) is available if reel format is not needed.

TSM-120-01-T-DV — Select this variant when tin contact finish is acceptable and cost optimization is a priority. Tube packaging suits manual assembly workflows. Operating temperature range of -55°C to 105°C is suitable for applications not requiring extended high-temperature operation. This variant represents the narrowest temperature specification among substitutes.

All substitute parts carry ROHS3 compliance, exceeding the RoHS Compliant status of the original part. All maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity level.

Frequently Asked Questions (FAQ)

Q: Can TSM-120 series connectors be used as direct replacements for the 95157-140TLF in existing designs?

A: Yes, all four TSM-120 variants are mechanically and electrically compatible. The 40-position, 2-row configuration with 0.100" pitch, male pin contacts, and identical mating contact length ensure footprint and interface compatibility. Verify that your application's operating temperature range does not exceed the substitute part's maximum specification.

Q: What is the difference between the gold-plated and tin-plated contact finishes?

A: The 95157-140TLF and three TSM-120 variants (TSM-120-01-L-DV-A-P-TR, TSM-120-01-S-DV, TSM-120-01-S-DV-P-TR) feature gold contact finish, which provides superior corrosion resistance and lower contact resistance over extended service life. The TSM-120-01-T-DV variant uses tin finish, which is acceptable for applications with shorter service intervals or lower corrosion exposure. Gold finish thickness varies: the original part specifies 30.0µin, while TSM-120-01-L-DV-A-P-TR specifies 10.0µin. Both thicknesses meet industry standards for connector reliability.

Q: Does packaging format affect electrical performance?

A: No. Tube and tape & reel packaging formats do not affect electrical or mechanical performance. Packaging selection is driven by assembly process requirements. Tape & reel (TR) variants are optimized for automated pick-and-place assembly, while tube variants suit manual assembly or lower-volume production. The TSM-120-01-L-DV-A-P-TR and TSM-120-01-S-DV-P-TR include pick-and-place features for automated handling.

Q: What is the operating temperature difference between the original part and substitutes?

A: The 95157-140TLF operates from -65°C to 130°C. The TSM-120 substitutes operate within narrower ranges: TSM-120-01-L-DV-A-P-TR, TSM-120-01-S-DV, and TSM-120-01-S-DV-P-TR operate from -55°C to 125°C; TSM-120-01-T-DV operates from -55°C to 105°C. Verify that your application's minimum and maximum operating temperatures fall within the selected substitute's specification.

Q: Are the TSM-120 connectors cuttable, and does this affect compatibility?

A: Yes, TSM-120 variants are designated as "Header, Cuttable," meaning the connector strip can be cut to shorter lengths if required. This feature does not affect compatibility with the 95157-140TLF when used as a full 40-position connector. The cuttable design provides design flexibility for future applications requiring fewer positions.

Q: What compliance certifications apply to these substitute parts?

A: All TSM-120 variants carry ROHS3 compliance, which exceeds the RoHS Compliant status of the original 95157-140TLF. All parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity level. REACH Unaffected status is documented for all Samtec variants.

Q: Can I mix packaging formats in the same design or production run?

A: Yes. Electrical and mechanical compatibility is independent of packaging format. However, assembly process optimization typically favors consistent packaging within a single production run to streamline handling and placement procedures.
