Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 520258-3 is based on electrical and mechanical parameter equivalence. The substitute part 5520258-3 maintains identical functional specifications across all critical parameters: connector type, contact configuration (6P6C), mounting method (through hole), orientation (vertical), termination type (solder), shielding classification (unshielded), and Category 3 rating. Physical characteristics including contact material (phosphor bronze), contact finish (gold plating at 50.0µin thickness), housing material (PBT polyester), operating temperature range (-40°C to 85°C), and mechanical features (board lock, panel stops, user-selectable tab direction) are preserved.

The primary distinction between the main part and substitute is product status and compliance certification. The 520258-3 is obsolete and RoHS non-compliant, while the 5520258-3 is active and RoHS compliant. Packaging differs between the two parts, with the substitute supplied in tray format compared to the main part's unspecified packaging.

Parameter Comparison

Engineering Selection Recommendations

The 5520258-3 is the direct substitute for the obsolete 520258-3 modular connector jack. All electrical and mechanical parameters are identical, ensuring functional equivalence in circuit applications. The substitute part is classified as active, providing assured long-term availability and procurement support.

For new designs and production applications, the 5520258-3 is the appropriate selection. This part carries RoHS compliance certification, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution. The REACH unaffected status of the 5520258-3 provides additional regulatory advantage over the main part.

Existing designs currently utilizing the 520258-3 can transition to the 5520258-3 without circuit modification or performance impact, as all functional specifications remain unchanged. The substitute part is supplied in tray packaging, which may require adjustment to procurement and handling procedures if the original part was supplied in alternative packaging formats.
