Substitute Part Grouping Explanation

Substitution between the main part 748634-1 and the equivalent part 5748634-1 is based on strict parameter matching across all critical electrical and mechanical specifications. Both components share identical connector style, type, position count, row configuration, shell size layout, contact type, mounting method, flange design, shielding features, shell material composition, dielectric material, and color. The substitute part maintains full functional and mechanical compatibility with the original component while offering enhanced product status and regulatory compliance. Substitution is valid when the following parameters are matched: D-Sub High Density receptacle configuration, 15-position female contact housing, 3-row arrangement, Size 1 (DE, E) shell layout, free-hanging in-line mounting, unthreaded housing flange, shielded steel tin-plated construction, and polyamide glass-filled dielectric material.
