Phoenix Contact 5443344 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 5443344 is a 10-position terminal block header with male pins, shrouded on two sides, featuring 0.200" (5.08mm) pitch and right-angle through-hole mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The BCDH series designation identifies this as a legacy product line, necessitating evaluation of current-generation equivalents that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5443344 is determined by strict equivalence across the following critical parameters:

• Position Configuration: 10 positions arranged as 5 per level across 2 levels
• Pitch Specification: 0.200" (5.08mm) center-to-center spacing
• Connector Type: Header with male pins, shrouded on both sides
• Orientation: 90° right-angle configuration
• Termination Method: Solder attachment to PCB
• Mounting: Through-hole technology
• Electrical Ratings: Minimum 10A IEC current and 400V IEC voltage capability
• Compliance: UL94 V-0 flammability rating and RoHS compliance
• Physical Dimensions: Contact tail length 0.126" (3.20mm) and insulation height 0.933" (23.70mm)

The Phoenix Contact 1842542 qualifies as a direct substitute based on matching all critical parameters while offering active product status and improved current rating under UL standards.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1842542 is the qualified substitute for the obsolete 5443344 based on the following engineering criteria:

Electrical Compatibility: Both parts maintain identical IEC electrical ratings (10A at 400V). The 1842542 provides enhanced UL current rating (15A versus 12A), representing improved performance margin without compromising the original design specification.

Mechanical Compatibility: Identical position count, pitch, orientation, and physical dimensions ensure direct PCB footprint compatibility. Both components feature the same contact tail length and insulation height, eliminating the need for PCB redesign.

Compliance and Certification: Both parts carry UL94 V-0 flammability certification and RoHS compliance status, meeting regulatory requirements for equivalent applications.

Product Status Advantage: The 1842542 maintains active product status with current manufacturing support, ensuring long-term availability and supply chain stability compared to the obsolete 5443344.

Material Consideration: The 1842542 uses polybutylene terephthalate (PBT) housing versus polyamide (PA) in the original part. PBT offers enhanced chemical resistance and dimensional stability, providing equivalent or superior performance in standard industrial environments.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1842542 be used as a direct replacement for the 5443344 without PCB modification?

A: Yes. Both parts share identical pitch (5.08mm), position configuration (10 positions, 5 per level), contact tail length (3.20mm), and insulation height (23.70mm). No PCB layout changes are required for substitution.

Q: What is the difference in current rating between these parts?

A: Under IEC standards, both parts are rated for 10A. Under UL standards, the 5443344 is rated for 12A while the 1842542 is rated for 15A. This represents an improvement in the substitute part with no reduction in capability.

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

A: No. Both parts maintain identical voltage ratings: 400V IEC and 300V UL.

Q: Why does the substitute part use PBT instead of polyamide?

A: Polybutylene terephthalate (PBT) is a modern engineering polymer offering improved chemical resistance, dimensional stability, and long-term performance compared to polyamide. Both materials meet UL94 V-0 flammability requirements and are suitable for industrial terminal block applications.

Q: Is the 1842542 available in the same packaging as the 5443344?

A: The 1842542 is supplied in bulk packaging, whereas the original 5443344 packaging specification was not provided. Confirm packaging requirements with your procurement process, as this does not affect electrical or mechanical compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both the 5443344 and 1842542 are RoHS compliant with MSL rating of 1 (unlimited moisture sensitivity level).

Q: What is the series designation difference?

A: The 5443344 belongs to the legacy BCDH series, while the 1842542 is part of the current COMBICON MDSTB series. The series change reflects Phoenix Contact's product line evolution while maintaining functional equivalence.
