Phoenix Contact 5452643 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 5452643 is a 4-position terminal block header with male pins, shrouded on two sides, featuring 0.200" (5.08mm) pitch and 90° right-angle orientation for through-hole mounting. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance. The BCDH series designation identifies this legacy connector family. Substitute parts must maintain identical electrical performance, mechanical fit, and mounting characteristics to ensure direct interchangeability in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 5452643 is determined by strict equivalence across the following critical parameters:

• Electrical Performance: Current rating (IEC: 10A minimum), voltage rating (IEC: 320V minimum), and contact mating finish (tin)
• Mechanical Configuration: 4-position count, 2 positions per level, 2 levels, 0.200" (5.08mm) pitch, 90° right-angle orientation
• Physical Dimensions: Contact tail length (0.126" / 3.20mm), insulation height (0.933" / 23.70mm)
• Mounting & Termination: Through-hole solder termination, shrouded (2 side) male pin design
• Compliance: RoHS compliance and MSL rating (1 - Unlimited)

The identified substitute part 1762091 meets all these criteria while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1762091 is the direct functional equivalent to the obsolete 5452643. Selection of part 1762091 is supported by:

• Electrical Equivalence: Identical current (10A IEC) and voltage (320V IEC) ratings ensure safe operation in existing circuits
• Mechanical Interchangeability: Matching position count, pitch, orientation, and physical dimensions (contact tail length, insulation height) guarantee PCB fit and mating compatibility
• Compliance Continuity: Both parts maintain RoHS compliance and MSL rating 1, preserving environmental and reliability standards
• Active Product Status: Part 1762091 is in active production, ensuring long-term availability and supply chain stability compared to the obsolete 5452643
• Manufacturer Consistency: Both parts are manufactured by Phoenix Contact, maintaining design integrity and quality standards

The transition from BCDH series to COMBICON MDSTB series represents Phoenix Contact's product line evolution while preserving functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1762091 be used as a direct replacement for 5452643 on existing PCBs?

A: Yes. The 1762091 maintains identical electrical ratings (10A IEC, 320V IEC), mechanical configuration (4-position, 0.200" pitch, 90° orientation), and physical dimensions (contact tail length, insulation height). Through-hole solder termination and shrouded male pin design are identical, enabling direct PCB substitution without layout modification.

Q: What is the difference between the BCDH and COMBICON MDSTB series?

A: BCDH is the legacy series designation for the obsolete 5452643. COMBICON MDSTB is the current Phoenix Contact series for equivalent terminal block headers. Both series share identical electrical and mechanical specifications for this 4-position configuration, representing product line consolidation by the manufacturer.

Q: Are there any compliance or certification differences between these parts?

A: No. Both 5452643 and 1762091 are RoHS compliant with MSL rating 1 (Unlimited). Electrical certifications (IEC and UL ratings) are identical, ensuring equivalent performance in regulated applications.

Q: What packaging differences exist between these parts?

A: The 5452643 is supplied in standard packaging, while 1762091 is supplied in bulk packaging. This packaging difference does not affect electrical or mechanical performance and is determined by procurement volume and logistics requirements.

Q: Why is the 5452643 listed as obsolete?

A: The 5452643 has been discontinued by Phoenix Contact as part of product line rationalization. The 1762091 represents the active equivalent within the current product portfolio, ensuring continued availability and manufacturer support.
