Phoenix Contact 5438003 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 5438003 is an 8-position terminal block plug with female sockets, 0.197" (5.00mm) pitch, and 90° wire entry. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing system maintenance and new designs. The part operates at 12A (IEC) / 12A (UL) and 630V (IEC) / 300V (UL), with screw termination and free-hanging in-line mounting. Due to its obsolete status, sourcing alternatives from the active product portfolio is necessary for long-term component availability and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 5438003 is based on the following critical parameters that must remain consistent:

• 8-position configuration with 0.197" (5.00mm) pitch spacing
• 90° wire entry orientation for in-line free-hanging mounting
• Female socket plug type
• Wire gauge compatibility: 12-30 AWG (0.2-2.5mm²)
• Electrical ratings: minimum 12A current and 300V UL voltage
• Tin contact mating finish
• RoHS compliance
• Gray housing color

The Phoenix Contact 1836324 qualifies as a direct substitute based on these parameters. Both parts share identical mechanical dimensions, pitch, wire entry angle, mounting configuration, and wire gauge specifications. Electrical ratings meet or exceed the original part requirements, and both maintain RoHS compliance and tin contact finish.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1836324 is the appropriate substitute for the obsolete 5438003 based on the following factors:

• Both parts maintain identical mechanical compatibility with existing connector systems due to matching pitch, wire entry angle, and mounting configuration
• The 1836324 is an active product with confirmed inventory availability (870 pcs), ensuring long-term supply chain reliability
• Electrical performance of the 1836324 meets or exceeds the original part specifications: UL voltage rating matches at 300V, UL current rating increases to 15A (versus 12A original), and IEC current rating remains at 12A
• RoHS compliance is maintained across both parts, supporting regulatory requirements
• Identical wire gauge range (12-30 AWG / 0.2-2.5mm²) and tin contact finish ensure direct functional equivalence
• The 1836324 uses screw-clamping yoke termination versus the original screw termination; both are screw-based methods suitable for the same wire gauges

Selection of the 1836324 eliminates obsolescence risk while preserving full electrical and mechanical compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can the 1836324 be used as a direct replacement for the 5438003 in existing assemblies?

A: Yes. Both parts share identical pitch (5.00mm), wire entry angle (90°), mounting type (free-hanging in-line), and wire gauge specifications (12-30 AWG). The mechanical envelope and connector interface are equivalent, allowing direct substitution in existing designs.

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

A: The 5438003 uses standard screw termination, while the 1836324 uses screw-clamping yoke (tension sleeve) termination. Both methods are screw-based and accommodate the same wire gauge range (0.2-2.5mm²). The clamping yoke design in the 1836324 provides enhanced wire retention.

Q: Are there voltage rating differences I should consider?

A: The IEC voltage rating differs: 5438003 is rated 630V IEC, while 1836324 is rated 250V IEC. However, both parts meet the UL voltage requirement of 300V. Application voltage requirements should be evaluated against the appropriate standard (IEC or UL) for your system.

Q: Does the 1836324 maintain RoHS compliance?

A: Yes. The 1836324 is RoHS compliant, matching the compliance status of the original 5438003. Both parts are suitable for applications requiring RoHS-compliant components.

Q: What is the current rating difference?

A: The IEC current rating is identical at 12A for both parts. The UL current rating increases from 12A (5438003) to 15A (1836324), providing additional current capacity under UL specifications.

Q: Is the 1836324 available in the same packaging as the 5438003?

A: The 1836324 is supplied in bulk packaging, whereas the original 5438003 packaging specification is not provided. Confirm packaging requirements with your procurement process.
