TE Connectivity 520425-2 Modular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 520425-2 is a jack modular connector with 6 positions and 4 contacts (6p4c), conforming to RJ11 and RJ14 standards. This connector is designed for vertical through-hole mounting with solder termination in unshielded Cat3 applications. The part is classified as obsolete, necessitating identification of active equivalent components for ongoing procurement and new design implementations. Substitute parts maintain identical electrical and mechanical specifications while offering improved product status and compliance certifications.

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 520425-2 is based on electrical and mechanical parameter equivalence. The substitute part 5520425-2 maintains identical specifications across all critical functional parameters: connector type, contact configuration (6p4c), mounting method (through hole vertical), termination type (solder), shielding classification (unshielded), and Cat3 rating. Both parts utilize phosphor bronze contacts with gold finish at 50.0µin thickness and operate across the same temperature range (-40°C ~ 85°C).

The primary distinction between the main part and substitute is product status and compliance certification. The 520425-2 is obsolete and RoHS non-compliant, while the 5520425-2 is active and RoHS compliant. Packaging differs between the two parts (unspecified for 520425-2 versus tray packaging for 5520425-2), and REACH status differs accordingly. These differences do not affect functional interchangeability in applications requiring the specified electrical and mechanical characteristics.

Parameter Comparison
