TSM-125-01-L-DV-P Equivalent & Substitute Parts

Part Overview

The TSM-125-01-L-DV-P is an active surface mount rectangular connector header manufactured by Samtec Inc. This 50-position, 2-row cuttable header is designed for board-to-board or cable applications with 0.100" (2.54mm) pitch spacing. The connector features gold-plated mating contacts, phosphor bronze material, and liquid crystal polymer insulation rated UL94 V-0. With 847 units in current stock and ROHS3 compliance, this component serves as a standard interconnect solution for applications requiring reliable surface mount header connectivity across extended temperature ranges.

Identifying equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and maintain compatibility across manufacturing batches and procurement cycles.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSM-125-01-L-DV-P is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Header, cuttable design with 50 positions in 2-row arrangement
• Pitch Specifications: 0.100" (2.54mm) mating pitch and 0.100" (2.54mm) row spacing
• Mounting & Termination: Surface mount with solder termination
• Contact Specifications: Male pin contacts with gold mating finish and phosphor bronze material
• Insulation & Materials: Liquid crystal polymer insulation with UL94 V-0 flammability rating
• Environmental Compliance: ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity level
• Operating Range: -55°C to 125°C temperature specification

Substitute parts must maintain identical electrical and mechanical parameters across all listed criteria. Variations in fastening type, contact finish thickness, or series designation do not disqualify substitution when core functional parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both TSM-125-01-L-DV-P and TSM-125-01-LM-DV-P are active products from Samtec Inc. with full ROHS3 compliance and identical electrical and mechanical specifications. The parts are functionally equivalent across all critical parameters including connector configuration, pitch, contact materials, insulation properties, and operating temperature range.

Selection between these parts should be based on inventory availability and procurement lead times. The TSM-125-01-LM-DV-P currently maintains higher stock levels (1046 units) compared to the TSM-125-01-L-DV-P (847 units), which may influence supply chain decisions. Both parts meet the same compliance certifications and environmental specifications, ensuring interchangeability in applications requiring 50-position, 2.54mm pitch surface mount headers.

Frequently Asked Questions (FAQ)

Q: Are TSM-125-01-L-DV-P and TSM-125-01-LM-DV-P fully interchangeable?

A: Yes. Both parts are functionally equivalent across all electrical and mechanical parameters. They share identical pitch spacing (0.100"), contact configuration (50-position, 2-row male pins), mounting type (surface mount), contact materials (phosphor bronze with gold plating), insulation specifications (LCP, UL94 V-0), and operating temperature range (-55°C to 125°C). Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between the part numbers TSM-125-01-L-DV-P and TSM-125-01-LM-DV-P?

A: The part numbers differ only in the designation between "L" and "LM" within the Samtec TSM series nomenclature. This variation does not affect electrical or mechanical compatibility. Both parts are manufactured by Samtec Inc. and maintain identical specifications for connector type, pitch, contact configuration, and material properties.

Q: Can I substitute TSM-125-01-LM-DV-P for TSM-125-01-L-DV-P in existing designs?

A: Yes. The TSM-125-01-LM-DV-P is a direct substitute for TSM-125-01-L-DV-P. No design modifications are required. Both parts feature identical mating pitch (0.100"), row spacing (0.100"), contact length (0.230"), insulation height (0.100"), and all other critical dimensions and electrical properties.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical certifications: ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 (Unlimited) moisture sensitivity level. Both are active products with full manufacturer support.

Q: Which part should I select based on availability?

A: Selection should be based on current inventory and procurement requirements. TSM-125-01-LM-DV-P currently has higher stock availability (1046 units) versus TSM-125-01-L-DV-P (847 units). For applications with flexible sourcing timelines, either part is suitable. For time-critical procurement, verify current inventory status with your supplier.
