Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 4-644463-0 is determined by strict equivalence across the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (10), pitch (0.156"), number of rows (1), cable termination method (IDC), wire gauge (22 AWG), contact finish (tin), and presence of closed-end and polarizing key features. All identified substitutes maintain identical electrical and mechanical specifications across these parameters, ensuring direct functional compatibility. The substitute part 4-643819-0 meets all substitution criteria while offering the advantage of active product status and higher inventory availability.
