Substitute Part Grouping Explanation

Substitution within the TMM series is determined by strict equivalence across the following critical parameters: connector type (Header), contact type (Male Pin), number of positions (20), pitch spacing (0.079" / 2.00mm), mounting type (Surface Mount), termination method (Solder), current rating (3.2A per Contact), and operating temperature range (-55°C ~ 125°C). Both the main part TMM-120-01-LM-S-SM and the substitute part TMM-120-01-L-S-SM share identical specifications across all these parameters, confirming direct substitutability. The difference in part numbering reflects variant coding within the TMM-120 base product family but does not alter electrical or mechanical compatibility.
