Phoenix Contact 5449597 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 5449597 is a 9-position terminal block plug with female sockets, 0.150" (3.81mm) pitch, designed for 90° free-hanging in-line applications. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The part operates at 8A (IEC/UL) and 320V (IEC) / 300V (UL), with screw termination and wire gauge compatibility from 14-30 AWG (0.2-1.5mm²).

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5449597 is determined by strict alignment across the following critical parameters:

Electrical Compatibility: Current rating (8A minimum), voltage rating (320V IEC minimum), and wire gauge range must match or exceed the original specification
Mechanical Compatibility: 9-position configuration, 0.150" (3.81mm) pitch, 90° wire entry orientation, and free-hanging in-line mounting type must be identical
Termination Interface: Screw-based termination is required; variations in screw mechanism (standard vs. rising cage clamp) are permissible if electrical and mechanical parameters remain equivalent
Material and Compliance: Housing material (Polyamide/Nylon), flammability rating (UL94 V-0), and RoHS compliance status must be maintained

The Phoenix Contact 1827198 qualifies as a direct substitute based on these criteria.

Engineering Selection Recommendations

The Phoenix Contact 1827198 is a qualified substitute for the obsolete 5449597 based on the following engineering criteria:

Electrical Equivalence: Both parts maintain identical current (8A) and voltage (320V IEC / 300V UL) ratings, ensuring no derating or circuit redesign is required.

Mechanical Compatibility: The 9-position, 0.150" (3.81mm) pitch configuration with 90° free-hanging in-line mounting is identical, permitting direct mechanical interchange without connector redesign.

Termination Compatibility: While the 1827198 employs a rising cage clamp screw mechanism compared to the standard screw termination of the 5449597, both utilize M2 screws with identical torque specifications (0.22-0.25 Nm). This variation does not compromise electrical or mechanical performance.

Wire Gauge Accommodation: The 1827198 supports a marginally extended lower wire gauge range (0.14-1.5mm² vs. 0.2-1.5mm²), providing enhanced flexibility without reducing compatibility with the original specification range.

Compliance Status: The 1827198 holds active product status with ROHS3 compliance, compared to the obsolete status of the 5449597. Both maintain UL94 V-0 flammability ratings and tin contact mating finishes.

Availability: The 1827198 is currently in active production with 1268 units in stock, compared to 776 units of the obsolete 5449597.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1827198 be used as a direct replacement for the 5449597 in existing installations?

A: Yes. The 1827198 meets all critical electrical, mechanical, and compliance parameters of the 5449597. The rising cage clamp termination mechanism does not affect compatibility, as both employ identical M2 screw specifications and torque values.

Q: What is the difference between standard screw termination and rising cage clamp termination?

A: Both termination methods use M2 screws with identical torque specifications (0.22-0.25 Nm). The rising cage clamp mechanism in the 1827198 provides an alternative wire retention method while maintaining electrical and mechanical equivalence.

Q: Does the extended wire gauge range of the 1827198 (0.14-1.5mm²) affect compatibility with the original 5449597 specification (0.2-1.5mm²)?

A: No. The 1827198 accommodates the full original wire gauge range and extends compatibility to smaller gauges. Existing installations using 0.2-1.5mm² wire remain fully compatible.

Q: What is the significance of the product status change from Obsolete to Active?

A: The 1827198 is in active production with current availability, ensuring long-term supply chain continuity. The 5449597, classified as obsolete, has limited future availability.

Q: Are there any compliance differences between the two parts?

A: Both parts maintain UL94 V-0 flammability ratings and tin contact finishes. The 1827198 holds ROHS3 compliance, representing an updated regulatory status compared to the RoHS Compliant designation of the 5449597.

Q: What packaging options are available for the 1827198?

A: The 1827198 is supplied in bulk packaging, compared to the unspecified packaging of the 5449597.
