Substitute Part Grouping Explanation

Substitution eligibility for the TSM-104-01-LM-SH-A is determined by strict equivalence across the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 4
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Surface Mount, Right Angle
• Contact Finish - Mating: Gold
• Contact Material: Phosphor Bronze
• Insulation Material: Liquid Crystal Polymer (LCP)
• Operating Temperature: -55°C ~ 125°C
• RoHS Status: ROHS3 Compliant
• Material Flammability Rating: UL94 V-0

The TSM-104-01-L-SH-A meets all substitution criteria and is classified as a direct equivalent within the TSM series. Both parts share identical electrical and mechanical specifications, with the primary distinction being manufacturing variant designation within the same product line.

Parameter Comparison
