Phoenix Contact 5443399 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 5443399 is a 20-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 active equivalent parts essential for ongoing design support and procurement continuity. The BCDH series designation identifies this legacy product line. Substitute parts must maintain identical mechanical and electrical interface characteristics to ensure direct compatibility in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5443399 is determined by strict equivalence across the following critical parameters:

• Position Configuration: 20 positions arranged as 10 per level across 2 levels
• Pitch Specification: 0.200" (5.08mm) center-to-center spacing
• Header Type: Male pins with two-side shrouding
• Orientation: 90° right-angle through-hole mounting
• Electrical Ratings: IEC compliance at 10A/400V minimum; UL compliance at 12A/300V minimum
• Termination: Solder-based connection
• Mechanical Interface: Contact tail length 0.126" (3.20mm) and insulation height 0.933" (23.70mm)
• Material Compliance: UL94 V-0 flammability rating and RoHS compliance

The substitute part Phoenix Contact 1842597 meets all these criteria while offering active product status and improved material composition (PBT housing versus polyamide).

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1842597 is a direct functional equivalent to the obsolete 5443399. Both components maintain identical electrical ratings under IEC and UL standards, mechanical dimensions, and interface specifications. The substitute part offers the advantage of active product status, ensuring long-term availability and supply chain continuity.

The housing material difference (PBT in the substitute versus polyamide in the original) does not affect electrical or mechanical compatibility. Both materials meet UL94 V-0 flammability requirements and RoHS compliance standards. The substitute's UL current rating of 15A exceeds the original 12A specification, providing additional design margin without introducing incompatibility.

Selection of the 1842597 substitute is appropriate for new designs, redesigns, and end-of-life replacement scenarios where the original 5443399 is no longer procurable.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1842597 be used as a direct replacement for the 5443399 in existing designs?

A: Yes. The 1842597 maintains identical pitch (0.200"/5.08mm), position count (20), orientation (90° right-angle), and electrical ratings (IEC 10A/400V, UL 12A/300V minimum). Mechanical dimensions including contact tail length and insulation height are identical, ensuring PCB compatibility without layout modifications.

Q: What is the significance of the housing material change from polyamide to PBT?

A: Both materials satisfy UL94 V-0 flammability classification and RoHS compliance requirements. PBT offers improved dimensional stability and chemical resistance. This material change does not affect electrical performance, mechanical fit, or regulatory compliance.

Q: Why is the original 5443399 classified as obsolete?

A: Product obsolescence reflects Phoenix Contact's product lifecycle management. The BCDH series has been superseded by the COMBICON MDSTB series, represented by the 1842597. Obsolete status indicates the manufacturer no longer produces the original part.

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

A: The 5443399 is listed with unspecified packaging, while the 1842597 is supplied in bulk packaging. This distinction affects procurement and handling but does not impact component functionality or compatibility.

Q: Does the higher UL current rating (15A) of the 1842597 create any compatibility issues?

A: No. A higher current rating in the substitute part provides additional design margin and does not create incompatibility. The substitute remains suitable for applications designed for the original 12A UL rating.

Q: What compliance certifications apply to both parts?

A: Both the 5443399 and 1842597 are RoHS compliant and carry UL94 V-0 material flammability ratings. Both meet IEC and UL electrical standards for terminal block applications.
