Substitute Part Grouping Explanation

Substitution of the obsolete 552725-2 with the active equivalent 5552725-2 is based on electrical and mechanical parameter alignment within the D-Sub receptacle connector category. Both parts maintain identical functional specifications across the following critical parameters:

Connector Type & Position Count: Both are 50 position receptacles with 2-row configuration
Mounting & Termination: Both feature panel mount, through-hole, right-angle solder termination
Connector Style: Both utilize outer shroud contacts
Contact Specifications: Both employ gold-plated contacts at 30.0µin (0.76µm) thickness
Series Classification: Both belong to the CHAMP .085 series

The primary differences between these parts relate to product lifecycle status, packaging configuration, and regulatory compliance posture rather than electrical or mechanical performance characteristics.
