Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSM-105-01-LM-SH-A is determined by strict equivalence across the following critical parameters:

Connector series, contact type, pitch, position count, row configuration, mounting orientation, termination method, contact material, insulation material, operating temperature range, and compliance certifications must remain identical. The substitute part TSM-105-01-L-SH-A meets all these criteria, differing only in the contact finish thickness designation notation (L versus LM suffix), which reflects manufacturing process variation within the same specification envelope.

Parameter Comparison
