Molex 0855070001 Equivalent & Substitute Parts

Part Overview

The Molex 0855070001 is a jack modular connector (8p8c/RJ45) designed for Ethernet applications with vertical through-hole mounting and shielding for Cat5e performance. This connector features board lock and panel stops, with phosphor bronze contacts finished in gold. The part is currently obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for new designs or production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters:

• Connector Type & Configuration: All substitutes must be 8p8c (RJ45) jack modular connectors with identical pin count and electrical interface
• Mounting & Orientation: Through-hole vertical mounting is mandatory for PCB compatibility
• Termination Method: Solder termination required for assembly process compatibility
• Shielding: Shielded construction required for EMI protection
• Contact Material & Finish: Phosphor bronze with gold plating (50.0µin minimum) ensures electrical performance and reliability
• Tab Direction: User selectable tab direction maintains mechanical interchangeability
• Operating Temperature Range: Minimum -40°C ~ 80°C required; substitutes with extended ranges (-40°C ~ 85°C) are acceptable
• Compliance: ROHS3 compliance and MSL 1 rating required for regulatory and manufacturing compatibility

The five substitute parts listed below meet all mandatory parameters. Variations in housing material, packaging format, and category rating (Cat3 vs. Cat5/Cat5e) do not affect mechanical or electrical substitutability for the core connector function.

Parameter Comparison

Engineering Selection Recommendations

All five substitute parts are active products from TE Connectivity AMP Connectors and maintain full mechanical and electrical compatibility with the obsolete Molex 0855070001. Selection among substitutes should be based on the following factors:

6368150-1 offers the highest inventory availability (1,000,300 units) and is recommended as the primary replacement for new designs or high-volume production. This part maintains Cat5 shielding performance and includes ROHS3 compliance certification.

5406436-1 is the manufacturer-recommended substitute with ROHS3 compliance and substantial inventory (9,670 units). The addition of EMI fingers provides enhanced shielding performance for Cat3 applications.

5557484-1, 5557969-2, and 6368115-1 are functionally equivalent alternatives with RoHS compliance and EMI finger shielding. These parts carry lower inventory levels but remain suitable for applications where specific packaging or delivery requirements necessitate alternative sourcing.

All substitutes support the extended operating temperature range of -40°C ~ 85°C, which exceeds the original specification and provides additional thermal margin for demanding environments.

Frequently Asked Questions (FAQ)

Q: Can these substitute parts be used interchangeably with the Molex 0855070001 on existing PCBs?

A: Yes. All substitute parts share identical through-hole mounting footprints, vertical orientation, solder termination, and user-selectable tab direction. Direct PCB-level substitution is mechanically and electrically compatible without design modification.

Q: What is the difference between Cat3 and Cat5/Cat5e ratings on these connectors?

A: Category ratings indicate bandwidth performance specifications. Cat5e (original part) supports up to 1 Gbps; Cat5 and Cat3 substitutes support lower bandwidth. For applications requiring Cat5e performance, 6368150-1 is specified as Cat5. For general Ethernet applications, Cat3-rated substitutes are functionally adequate.

Q: Do the EMI fingers on some substitute parts affect compatibility?

A: No. EMI fingers provide additional electromagnetic interference shielding and do not affect mechanical compatibility or electrical interface. Their presence is a performance enhancement, not a compatibility constraint.

Q: What is the significance of the extended operating temperature range (-40°C ~ 85°C vs. -40°C ~ 80°C)?

A: The substitute parts support a 5°C higher maximum operating temperature. This provides additional thermal margin and is fully backward compatible with applications designed for the original -40°C ~ 80°C range.

Q: How do packaging differences (Tray vs. Tube) affect part selection?

A: Packaging affects handling, storage, and supply chain logistics but does not impact electrical or mechanical performance. Selection should align with manufacturing assembly processes and inventory management requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitutes meet RoHS compliance requirements. The original part and 6368150-1 carry ROHS3 certification; 5406436-1, 5557484-1, 5557969-2, and 6368115-1 carry RoHS compliance certification. Both certifications satisfy regulatory requirements for electronic component manufacturing.
