TSM-104-01-L-DV-M-TR Equivalent & Substitute Parts

Part Overview

The TSM-104-01-L-DV-M-TR is an active rectangular connector header manufactured by Samtec Inc. This surface mount connector features 8 positions arranged in 2 rows with 0.100" (2.54mm) pitch, designed for board-to-board or cable applications. The part is cuttable, unshrouded, and utilizes solder termination with push-pull fastening. Finding equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate different manufacturing or assembly requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSM-104-01-L-DV-M-TR is determined by strict alignment of the following critical parameters:

• Connector Type: Header, Cuttable
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 8
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Insulation Material: Liquid Crystal Polymer (LCP)
• Operating Temperature Range: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0

Substitute parts must maintain these parameters to ensure mechanical fit, electrical performance, and thermal reliability. Variations in contact finish thickness, contact material composition, or insulation material type represent acceptable substitutions when all critical parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

TSM-104-01-S-DV-M-TR (Samtec Inc.) is a direct equivalent substitute for the TSM-104-01-L-DV-M-TR. Both parts are manufactured by Samtec Inc., share identical connector specifications, and maintain the same operating temperature range and material flammability rating. The primary difference is contact finish thickness on the mating surface (30.0µin versus 10.0µin), which does not affect mechanical compatibility or electrical performance. Both parts are ROHS3 compliant and carry MSL 1 rating.

M20-8760442 (Harwin Inc.) is a functional substitute with the following considerations: The part maintains identical pitch, position count, row configuration, and mounting type. However, the insulation material differs (Polyamide PA6T/Nylon 6T versus Liquid Crystal Polymer), and the operating temperature range is narrower (-40°C ~ 105°C versus -55°C ~ 125°C). The contact material is brass rather than phosphor bronze. The M20-8760442 provides specified current and voltage ratings (3A per contact, 250V) not listed for the main part. This part is ROHS3 compliant and carries MSL 1 rating. Selection of M20-8760442 requires confirmation that the reduced operating temperature range and alternative insulation material are acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can TSM-104-01-S-DV-M-TR be used as a direct replacement for TSM-104-01-L-DV-M-TR?

A: Yes. Both parts are manufactured by Samtec Inc. and share identical electrical and mechanical specifications including pitch, position count, row spacing, mounting type, termination method, and operating temperature range. The contact finish thickness difference does not affect compatibility.

Q: What are the key differences between the Samtec and Harwin substitute parts?

A: The primary differences are insulation material (Polyamide PA6T/Nylon 6T versus Liquid Crystal Polymer), operating temperature range (-40°C ~ 105°C versus -55°C ~ 125°C), and contact material (Brass versus Phosphor Bronze). Mechanical fit and pitch specifications remain identical.

Q: Is the M20-8760442 suitable for applications requiring the full -55°C ~ 125°C operating range?

A: No. The M20-8760442 operates only to -40°C ~ 105°C. Applications requiring the full temperature range of the main part must use TSM-104-01-L-DV-M-TR or TSM-104-01-S-DV-M-TR.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. TSM-104-01-L-DV-M-TR, TSM-104-01-S-DV-M-TR, and M20-8760442 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the significance of contact finish thickness variation?

A: Contact finish thickness affects durability and wear resistance during mating cycles. The TSM-104-01-S-DV-M-TR provides thicker gold plating (30.0µin versus 10.0µin), which may extend contact life in high-cycle applications. Both thicknesses are acceptable for standard applications.

Q: Can these parts be used interchangeably in existing designs?

A: TSM-104-01-L-DV-M-TR and TSM-104-01-S-DV-M-TR are fully interchangeable. M20-8760442 requires design review to confirm compatibility with the application's operating temperature range and insulation material requirements.
