Phoenix Contact 1657892 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1657892 is a 5-position terminal block plug with female sockets designed for 180° free-hanging (in-line) applications. This component features screwless spring cage termination, rated for 16A at 24V, and supports wire gauges from 14 AWG (0.75-2.5mm²). The part operates across -40°C to 70°C and meets IP65/IP67 ingress protection standards with UL94 V-0 flammability rating.

This part carries an obsolete product status. Identifying equivalent substitutes ensures design continuity and maintains supply chain reliability for applications requiring compatible 5-position terminal block plugs with matching electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1657892 is determined by the following critical parameters:

Electrical Compatibility: Current rating of 16A UL and 24V UL voltage rating are mandatory. The substitute must support these electrical specifications without derating.

Mechanical Compatibility: The substitute must maintain 5 positions in a single level configuration with 180° free-hanging (in-line) mounting. Female socket plug type is required for connector mating.

Termination and Wire Support: While the original uses screwless spring cage with tension clamp termination, alternative screwless termination methods (such as leg spring or push-in spring) are acceptable provided they support the same wire gauge range or compatible range (14 AWG / 0.75-2.5mm² or 13-18 AWG equivalent).

Environmental and Compliance Standards: Operating temperature range, flammability rating (UL94 V-0), and ingress protection (minimum IP67) must be maintained. RoHS compliance is required.

The substitute part 1425514 meets these criteria through equivalent electrical ratings, matching position configuration, compatible termination methodology, and active product status with enhanced environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1425514 is the designated manufacturer-recommended substitute for the obsolete 1657892. Both components are manufactured by Phoenix Contact and maintain identical electrical ratings (16A at 24V) and mechanical configuration (5-position, 180° free-hanging plug with female sockets).

The substitute offers enhanced specifications: extended operating temperature range (-40°C to 85°C versus -40°C to 70°C), improved ingress protection (IP67 versus IP65/IP67), and active product status ensuring ongoing availability and supply chain support. Wire gauge compatibility is maintained within the 13-18 AWG range, which encompasses the original 14 AWG specification.

Both components meet UL94 V-0 flammability requirements and RoHS compliance standards. The substitute carries ROHS3 compliance and REACH affected status, reflecting current regulatory alignment. Termination methodology differs (leg spring/push-in spring versus spring cage/tension clamp), but both employ screwless technology suitable for the same application class.

Frequently Asked Questions (FAQ)

Q: Can the 1425514 directly replace the 1657892 in existing designs?

A: Yes. Both components share identical electrical ratings (16A, 24V), position configuration (5-position single level), mounting type (180° free-hanging), and connector gender (female sockets). The substitute meets or exceeds all critical parameters required for functional equivalence.

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

A: The original 1657892 uses spring cage with tension clamp termination. The substitute 1425514 employs leg spring with push-in spring termination. Both are screwless technologies designed for tool-free wire insertion and secure retention, suitable for the same application requirements.

Q: Does the wire gauge difference affect compatibility?

A: The original supports 14 AWG (0.75-2.5mm²). The substitute supports 13-18 AWG. This broader range is backward compatible with 14 AWG wire, ensuring existing harnesses and wire specifications remain valid.

Q: Why is the operating temperature range extended in the substitute?

A: The 1425514 operates to 85°C versus 70°C for the original. This represents an enhancement in thermal capability and does not restrict applications designed for the original temperature range.

Q: Are there packaging differences between these parts?

A: The original 1657892 is listed as obsolete with no specified packaging. The substitute 1425514 is supplied in bulk packaging and maintains active product status with current inventory availability.

Q: Do both parts meet the same compliance standards?

A: Both meet UL94 V-0 flammability and RoHS requirements. The substitute carries ROHS3 compliance and REACH affected status, reflecting current regulatory frameworks. Both are rated for IP67 ingress protection (the original also supports IP65).
