TSM-102-02-L-SH-A-P-TR Equivalent & Substitute Parts

Part Overview

The TSM-102-02-L-SH-A-P-TR is a surface mount, right-angle rectangular connector header manufactured by Samtec Inc. in the TSM series. This 2-position connector operates at 0.100" (2.54mm) pitch and features male pins with gold-plated mating contacts. The part is Active status and RoHS3 compliant, designed for board-to-board or cable applications with solder termination and push-pull fastening.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's specifications, enabling functional interchangeability in applications where mounting type or packaging format differences are acceptable.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 640453-2 (TE Connectivity AMP Connectors, MTA-100 series) qualifies as an equivalent based on the following critical parameters:

• Connector type: Header
• Contact type: Male pin
• Pitch - mating: 0.100" (2.54mm)
• Number of positions: 2
• Number of rows: 1
• Shrouding: Unshrouded
• Termination: Solder
• Contact shape: Square
• Material flammability rating: UL94 V-0
• RoHS3 compliance: Yes
• Moisture sensitivity level: 1 (Unlimited)

The primary difference is mounting type: TSM-102-02-L-SH-A-P-TR is surface mount right-angle, while 640453-2 is through-hole right-angle. Both maintain equivalent electrical and mechanical interface characteristics at the mating surface.

Parameter Comparison

Engineering Selection Recommendations

Both TSM-102-02-L-SH-A-P-TR and 640453-2 are Active status products with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts depends on board-level mounting requirements:

• TSM-102-02-L-SH-A-P-TR: Select for surface mount applications requiring SMD assembly processes and pick-and-place compatibility.
• 640453-2: Select for through-hole applications where PCB mounting holes are available and wave soldering or manual soldering processes are employed.

The TSM-102-02-L-SH-A-P-TR operates to 125°C maximum, while 640453-2 operates to 105°C maximum. Applications requiring the full 125°C upper temperature limit must use the Samtec part. Contact finish differences (gold vs. tin) and insulation material variations (LCP vs. thermoplastic) are secondary considerations when mounting type is the primary design constraint.

Frequently Asked Questions (FAQ)

Q: Can 640453-2 directly replace TSM-102-02-L-SH-A-P-TR on an existing PCB?

A: Direct replacement requires PCB redesign. TSM-102-02-L-SH-A-P-TR is surface mount; 640453-2 is through-hole. Pad layouts and mounting hole patterns differ. Both connectors maintain identical mating pitch (2.54mm) and position count (2), but board-level footprints are incompatible.

Q: Are the mating contacts electrically equivalent?

A: Yes. Both parts feature 0.100" (2.54mm) pitch, square male pins, and unshrouded headers. Mating interface dimensions and contact geometry are equivalent. Contact finish differences (gold vs. tin) do not affect electrical compatibility with standard 2.54mm pitch receptacles.

Q: What is the temperature operating range difference?

A: TSM-102-02-L-SH-A-P-TR operates -55°C to 125°C. 640453-2 operates -55°C to 105°C. Applications requiring sustained operation above 105°C must use the Samtec part.

Q: Are both parts RoHS3 compliant?

A: Yes. Both TSM-102-02-L-SH-A-P-TR and 640453-2 are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What packaging formats are available?

A: TSM-102-02-L-SH-A-P-TR is supplied in Tape & Reel (TR) format for automated assembly. 640453-2 is supplied in Bulk packaging. Packaging selection depends on production volume and assembly process requirements.
