Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 555387-2 is based on electrical and mechanical parameter equivalence within the D-Sub receptacle connector category. The substitute part 5555387-2 maintains identical specifications across all critical functional parameters: 50-position configuration, 2-row arrangement, panel mount through-hole right-angle solder termination, outer shroud contact style, CHAMP .085 series designation, board lock and shielding features, gold contact finish, and 4-40 housing/shell flange.

The primary distinction between the main part and substitute is product status and regulatory compliance. The 555387-2 is obsolete and RoHS non-compliant, while the 5555387-2 is active and ROHS3 compliant. Both parts share identical electrical and mechanical characteristics, making the 5555387-2 a direct functional equivalent suitable for new designs and replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The 5555387-2 is the direct active equivalent for the obsolete 555387-2. Selection of the 5555387-2 is appropriate for all applications requiring a 50-position D-Sub receptacle connector with the specified electrical and mechanical characteristics.

For new product designs, the 5555387-2 is the recommended selection due to its active product status and ROHS3 compliance. This part maintains full functional and dimensional compatibility with the 555387-2 while providing current regulatory compliance and assured long-term availability.

For legacy system maintenance or replacement applications where the original 555387-2 is specified, the 5555387-2 provides direct substitution without design modification. The identical electrical and mechanical parameters ensure seamless integration into existing assemblies and printed circuit board layouts.
