Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 5451064 is determined by strict equivalence across the following critical parameters:

Connector Interface: 12 positions, 0.200" (5.08mm) pitch, female socket configuration
Electrical Ratings: Minimum 12A at 630V (IEC), 300V (UL)
Mechanical Compatibility: 90° wire entry, free-hanging in-line mounting, M3 screw termination
Wire Acceptance: 12-30 AWG (0.2-2.5mm²) wire gauge range
Material & Safety: Polyamide housing, UL94 V-0 flammability rating

The substitute part Phoenix Contact 1792346 meets all these criteria while offering active product status and enhanced termination technology (rising cage clamp).

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1792346 be used as a direct replacement for the 5451064?

A: Yes. Both components feature identical 12-position, 0.200" (5.08mm) pitch female socket configurations, 90° wire entry orientation, and free-hanging in-line mounting. Electrical ratings (IEC), wire gauge acceptance, and mechanical dimensions are equivalent, enabling direct substitution without circuit or mechanical redesign.

Q: What is the difference in termination technology between these parts?

A: The 5451064 uses standard screw termination, while the 1792346 incorporates rising cage clamp technology. Both accept the same wire gauge range (12-30 AWG) and maintain identical screw torque specifications (0.5-0.6 Nm). The rising cage clamp design in the 1792346 provides enhanced wire retention characteristics.

Q: Are there packaging differences between these parts?

A: The 5451064 is supplied with unspecified packaging, while the 1792346 is supplied in bulk packaging. Both are identical in form, fit, and function. Packaging selection should be based on procurement volume and inventory management requirements.

Q: Does the higher UL current rating of the 1792346 affect compatibility?

A: No. The 1792346's 15A UL rating exceeds the 5451064's 12A UL rating, providing additional design margin. This higher rating does not create incompatibility; it represents an improvement in electrical capacity. Both components maintain identical IEC ratings (12A at 630V).

Q: Are both parts RoHS compliant?

A: Yes. The 5451064 is RoHS Compliant, and the 1792346 is ROHS3 Compliant. Both meet current environmental and hazardous substance restrictions. The 1792346's ROHS3 certification reflects current regulatory standards.

Q: What is the significance of the 1792346's active product status?

A: Active product status indicates current manufacturing and availability. The 5451064 is obsolete, meaning production has ended. Selecting the 1792346 ensures access to current inventory, technical support, and long-term supply chain reliability for new designs and ongoing maintenance applications.
