Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSM-120-01-L-DV-P is determined by strict alignment of the following critical parameters:

• Connector Configuration: 40 positions, 2 rows, 0.100" (2.54mm) pitch and row spacing
• Mounting Technology: Surface mount with solder termination
• Contact Type: Male pin configuration
• Fastening Mechanism: Push-pull fastening
• Insulation Height: 0.100" (2.54mm)
• Contact Shape: Square
• Contact Material: Phosphor bronze
• Shrouding: Unshrouded
• Flammability Compliance: UL94 V-0
• Environmental Classification: MSL 1 (Unlimited)

The identified substitute parts meet these core requirements. Variations in contact finish, insulation material composition, contact length tolerances, and packaging format are within acceptable substitution parameters for this connector category.

Engineering Selection Recommendations

All identified substitute parts maintain active production status and comply with RoHS environmental regulations. Selection between the main part and substitutes is based on the following considerations:

TSM-120-01-L-DV-P (Primary Part): Samtec TSM series with LCP insulation material, gold-plated mating contacts, and cuttable header configuration. ROHS3 compliant. Operating temperature range -55°C to 125°C. Suitable for applications requiring LCP insulation properties and cuttable header design.

95278-101-40LF (Amphenol ICC Substitute): BERGSTIK® series with thermoplastic insulation, gold-plated mating contacts with GXT™ enhancement, and breakaway header configuration. RoHS compliant. Extended operating temperature range -65°C to 125°C. Bulk packaging. Current rating specified at 3A per contact.

95278-401A40LF (Amphenol ICC Substitute): BERGSTIK® series with thermoplastic insulation, tin-plated mating contacts, and breakaway header configuration. RoHS compliant. Extended operating temperature range -65°C to 125°C. Cut tape packaging with pick-and-place features. Current rating specified at 3A per contact.

TSM-120-01-LM-DV-P (Samtec Substitute): Samtec TSM series variant with LCP insulation material, gold-plated mating contacts, and cuttable header configuration. ROHS3 compliant. Operating temperature range -55°C to 125°C. Tube packaging. Functionally equivalent to the primary part with identical electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can the 95278-101-40LF and 95278-401A40LF be used interchangeably with the TSM-120-01-L-DV-P?

A: Both Amphenol ICC parts meet the core substitution criteria: 40-position, 2-row configuration with 0.100" (2.54mm) pitch, surface mount solder termination, and push-pull fastening. The primary differences are insulation material (thermoplastic versus LCP), contact finish (gold with GXT™ or tin versus gold), and packaging format. Compatibility depends on application-specific requirements for insulation material properties and contact finish performance.

Q: What is the difference between the cuttable and breakaway header configurations?

A: The TSM-120-01-L-DV-P and TSM-120-01-LM-DV-P feature cuttable headers, allowing individual rows or sections to be separated by cutting. The Amphenol ICC 95278 series features breakaway headers, which separate along predetermined break points. Both configurations support the same 40-position, 2-row electrical interface.

Q: Are there differences in contact finish durability between the substitute parts?

A: Contact finish thickness varies across the parts. The TSM-120-01-L-DV-P and TSM-120-01-LM-DV-P specify 10.0µin (0.25µm) gold plating. The 95278-101-40LF specifies 30.0µin (0.76µm) gold with GXT™ enhancement. The 95278-401A40LF specifies 78.7µin (2.00µm) tin plating. Thicker finishes provide enhanced durability in high-cycle mating applications.

Q: What is the significance of the extended operating temperature range in the Amphenol ICC parts?

A: The 95278-101-40LF and 95278-401A40LF support -65°C to 125°C, compared to -55°C to 125°C for the Samtec parts. This extended lower temperature limit accommodates applications requiring operation in colder environments.

Q: How do packaging formats affect part selection?

A: The TSM-120-01-L-DV-P is supplied in tube packaging. The TSM-120-01-LM-DV-P is also supplied in tube packaging. The 95278-101-40LF is supplied in bulk packaging. The 95278-401A40LF is supplied in cut tape with pick-and-place features. Packaging selection depends on assembly process requirements and inventory management preferences.

Q: Are all substitute parts RoHS compliant?

A: Yes. The TSM-120-01-L-DV-P and TSM-120-01-LM-DV-P are ROHS3 compliant. The 95278-101-40LF and 95278-401A40LF are RoHS compliant. All parts meet environmental regulatory requirements.
