Phoenix Contact 5438993 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 5438993 is a 4-position terminal block plug with female sockets, 0.200" (5.08mm) pitch, designed for 90° free-hanging in-line applications. This component features screw termination, rated for 12A at 630V (IEC) and 12A at 300V (UL), and accommodates wire gauges from 12-30 AWG (0.2-2.5mm²). The part is currently obsolete, making equivalent substitutes necessary for ongoing system maintenance and new designs requiring compatible connectivity solutions.

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5438993 is determined by strict alignment with the following core parameters:

Connector Type & Configuration: 4-position plug with female sockets
Pitch Specification: 0.200" (5.08mm) center-to-center spacing
Mounting & Orientation: Free hanging in-line with 90° wire entry
Electrical Ratings: Minimum 12A current capacity (IEC) and 630V voltage rating (IEC)
Wire Compatibility: Support for 12-30 AWG (0.2-2.5mm²) wire gauges
Termination Method: Screw-based wire termination
Housing & Safety: Polyamide/Nylon construction with UL94 V-0 flammability rating

The Phoenix Contact 1835119 qualifies as a direct substitute based on full alignment with these parameters. Both components share identical pitch, position count, mounting configuration, wire entry angle, and core electrical specifications. Variations in termination mechanism (rising cage clamp vs. standard screw) and housing color do not affect functional interchangeability within the specified electrical and mechanical constraints.

Engineering Selection Recommendations

The Phoenix Contact 1835119 is the qualified substitute for the obsolete 5438993 based on product status and regulatory compliance. The 5438993 is obsolete with no ongoing manufacturing support, while the 1835119 is active and maintains current production availability. Both components meet identical IEC electrical specifications (12A at 630V) and share the same mechanical interface parameters.

The 1835119 offers enhanced UL current rating (15A vs. 12A) and improved RoHS3 compliance status compared to the original part. The rising cage clamp termination mechanism in the 1835119 provides equivalent screw-based wire retention with additional mechanical security features. These enhancements do not compromise backward compatibility within the specified electrical and mechanical operating envelope.

For applications requiring the exact original termination style, the 1835119 remains functionally equivalent due to identical screw torque specifications (0.5-0.6 Nm) and wire gauge accommodation (12-30 AWG). The housing color difference (gray to green) is a cosmetic variation without technical impact on system performance.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1835119 directly replace the 5438993 in existing installations?

A: Yes. Both components share identical pitch (5.08mm), position count (4), mounting configuration (free hanging in-line), wire entry angle (90°), and core electrical ratings (12A at 630V IEC). The 1835119 meets or exceeds all specified parameters of the obsolete 5438993.

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

A: Both termination methods use M3 screws with identical torque specifications (0.5-0.6 Nm). The rising cage clamp in the 1835119 provides an additional mechanical retention feature for the wire during insertion. Both methods accommodate the same wire gauge range (12-30 AWG) and deliver equivalent electrical performance.

Q: Are there packaging differences between these parts?

A: The 5438993 is supplied in standard packaging, while the 1835119 is supplied in bulk packaging. This difference affects order quantities and logistics but does not impact component functionality or electrical characteristics.

Q: Does the housing color change from gray to green affect compatibility?

A: No. Housing color is a cosmetic designation and does not affect electrical performance, mechanical fit, or system compatibility. Both components use identical Polyamide (PA) Nylon material with UL94 V-0 flammability rating.

Q: What is the inventory status for these parts?

A: The 5438993 (obsolete) has 1074 pcs in stock. The 1835119 (active) has 1125 pcs in stock. For new designs and ongoing maintenance, the 1835119 is the recommended selection due to active product status and continued manufacturing support.

Q: Are both parts RoHS compliant?

A: Yes. The 5438993 is RoHS Compliant. The 1835119 is ROHS3 Compliant, representing an enhanced compliance status. Both meet current environmental and hazardous substance restrictions.
