Phoenix Contact 1407409 Modular Connector RJ45 Jack - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1407409 is a modular jack connector with 8 positions/8 contacts (RJ45, Ethernet) configured for vertical through-hole mounting with shielding. This component is rated for Cat5e applications and features a board lock mechanism. The part is currently classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where Cat5e performance is acceptable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1407409 is determined by the following core parameters:

• Connector Type & Contact Configuration: Must be RJ45 jack with 8p8c contact arrangement
• Mounting & Orientation: Must support through-hole vertical mounting
• Termination Method: Must use solder termination
• Shielding: Must provide electromagnetic shielding
• Port Count & Row Configuration: Must be single port, single row
• Ingress Protection: Must maintain IP20 rating
• Tab Mechanism: Must feature user-selectable tab direction

The Phoenix Contact 1653090 meets all substitution criteria. While it offers enhanced specifications (Cat6 rating, EMI finger shielding, gold-plated contacts, active product status), it maintains full compatibility with the core mechanical and electrical parameters required for direct substitution.

Engineering Selection Recommendations

The Phoenix Contact 1653090 is the direct functional equivalent for the obsolete 1407409. Selection should be based on the following factors:

Product Status: The 1653090 maintains active product status with current manufacturing support, whereas the 1407409 is obsolete. For new designs or long-term system support, the 1653090 is the appropriate choice.

Compliance & Certifications: Both parts are RoHS compliant. The 1653090 meets ROHS3 requirements and is REACH unaffected, providing enhanced regulatory alignment for current applications.

Performance Specifications: The 1653090 provides Cat6 rating compared to the Cat5e rating of the 1407409. This represents an enhancement in bandwidth capability while maintaining backward compatibility with Cat5e installations. The addition of EMI finger shielding in the 1653090 provides improved electromagnetic interference rejection.

Environmental Operating Range: The 1653090 supports -25°C to 80°C operation versus -40°C to 70°C for the 1407409. Applications requiring the full -40°C lower temperature limit of the original part require evaluation of specific thermal requirements.

Contact Material & Finish: The 1653090 features copper alloy contacts with gold plating, enhancing corrosion resistance and contact reliability compared to the unspecified contact material of the 1407409.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1653090 directly replace the 1407409 in existing designs?

A: Yes. Both parts share identical mechanical mounting (through-hole vertical), electrical contact configuration (8p8c RJ45), termination method (solder), and shielding approach. The 1653090 is mechanically and electrically compatible for direct substitution.

Q: What is the difference between Cat5e and Cat6 ratings?

A: Cat5e supports bandwidth up to 1 Gbps, while Cat6 supports up to 10 Gbps. The 1653090's Cat6 rating provides enhanced performance headroom. Existing Cat5e installations will function without modification when upgraded to Cat6 connectors.

Q: Does the EMI finger shielding in the 1653090 affect compatibility?

A: No. EMI finger shielding is an enhancement that provides additional electromagnetic interference rejection. It does not affect mechanical fit or electrical compatibility with standard RJ45 cable assemblies.

Q: Are there packaging differences between these parts?

A: The 1407409 packaging is unspecified in available documentation. The 1653090 is supplied in bulk packaging. Confirm packaging requirements for your procurement process.

Q: What is the significance of the operating temperature range difference?

A: The 1407409 operates from -40°C to 70°C, while the 1653090 operates from -25°C to 80°C. For applications requiring operation below -25°C, the original 1407409 specifications must be maintained. For standard industrial and commercial applications, the 1653090 range is sufficient.

Q: Is the gold plating on the 1653090 contacts necessary?

A: Gold plating enhances contact reliability and corrosion resistance, particularly in environments with moisture or corrosive atmospheres. For standard applications, both plated and unplated contacts function equivalently. Gold plating extends contact life in demanding environments.
