Molex 0428786264 Modular Connector Jack 6P6C Equivalent & Substitute Parts

Part Overview

The Molex 0428786264 is a modular connector jack with 6 positions and 6 contacts (6P6C), configured for RJ11, RJ12, RJ14, and RJ25 applications. This vertical, unshielded connector features through-hole solder termination and is rated for Category 3 performance. The part is currently obsolete, making identification of active equivalent components essential for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution of the Molex 0428786264 is determined by strict equivalence across the following parameters:

Connector type (Jack)
Contact configuration (6P6C for RJ11, RJ12, RJ14, RJ25 compatibility)
Mounting method (Through Hole)
Physical orientation (Vertical)
Termination approach (Solder)
Electrical shielding classification (Unshielded)
Performance rating (Cat3)
Contact material composition (Phosphor Bronze)
Contact finish specification (Gold plating at 50.0µin thickness)
Thermal operating range (-40°C to 85°C)

The TE Connectivity AMP Connectors part 5520258-3 meets all these criteria and is classified as an active, manufacturer-recommended substitute.

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 5520258-3 is the designated manufacturer-recommended substitute for the obsolete Molex 0428786264. This substitution is supported by complete electrical and mechanical parameter equivalence across all critical specifications.

The TE Connectivity part maintains active product status, ensuring long-term availability and supply chain continuity. Both components carry equivalent compliance certifications: RoHS compliance, MSL Level 1 (unlimited moisture sensitivity), and identical export classification (EAR99). The housing material composition differs slightly (PBT/Polyester versus Polyester/Glass Filled), but both formulations are compatible with the specified operating temperature range of -40°C to 85°C.

For applications currently using the Molex 0428786264, direct substitution with the TE Connectivity 5520258-3 is supported without design modification, provided that mechanical fit and PCB layout accommodate the substitute component's physical dimensions.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5520258-3 be used as a direct replacement for the Molex 0428786264?

A: Yes. Both components are 6P6C jack connectors with vertical through-hole solder termination, unshielded Cat3 rating, and identical contact material and finish specifications. All electrical and mechanical parameters are equivalent.

Q: Why is the Molex part listed as obsolete?

A: The Molex 0428786264 has reached end-of-life status. The TE Connectivity 5520258-3 is the active equivalent and is recommended for new designs and ongoing procurement.

Q: Are there differences in housing material between these parts?

A: The Molex part uses Polyester with glass filler, while the TE Connectivity part uses Polybutylene Terephthalate (PBT) with Polyester. Both materials support the same operating temperature range (-40°C to 85°C) and are suitable for Cat3 modular connector applications.

Q: What is the packaging difference?

A: The Molex 0428786264 packaging specification is not provided. The TE Connectivity 5520258-3 is supplied in Tray packaging.

Q: Are both parts RoHS compliant?

A: Yes. The Molex 0428786264 is RoHS3 Compliant, and the TE Connectivity 5520258-3 is RoHS Compliant. Both meet regulatory requirements for hazardous substance restrictions.

Q: What is the moisture sensitivity level for these connectors?

A: Both components are classified as MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
