Substitute Part Grouping Explanation

Substitution of the TE Connectivity 644460-6 is determined by strict equivalence across the following critical parameters: connector type (receptacle), number of positions (6), pitch specification (0.156"), contact type (female socket), wire gauge (18 AWG), cable termination method (IDC), contact finish (gold), mounting configuration (free hanging in-line), and series designation (MTA-156). The substitute part 3-644460-6 maintains complete electrical and mechanical compatibility with the original component across all specified parameters. The primary distinction between these parts is product status and packaging configuration, with the substitute part classified as active and available in bulk packaging, whereas the original part is obsolete.
