Engineering Selection Recommendations
The 5552403-1 serves as the direct active equivalent to the obsolete 552403-1. Both connectors maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction between the two parts is product status and regulatory compliance.
The 552403-1 is classified as obsolete and carries RoHS non-compliant status. The 5552403-1 is an active product with ROHS3 compliance, making it suitable for applications subject to current environmental and regulatory requirements. The 5552403-1 also includes specified contact finish thickness of 30.0µin (0.76µm), providing additional process documentation.
For new designs and ongoing production requiring 50-position right-angle IDC receptacle connectors in the CHAMP .085 series, the 5552403-1 is the appropriate selection. For legacy system maintenance where RoHS compliance is not mandated, either part maintains functional equivalence.
