Phoenix Contact 5437473 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 5437473 is an 8-position terminal block header with male pins, shrouded on four 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 design provides reliable solder termination for applications requiring secure electrical connections with dual-level positioning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5437473 is determined by strict alignment of the following critical parameters:

• Number of positions: 8 (fixed requirement)
• Positions per level: 4 (fixed requirement)
• Number of levels: 2 (fixed requirement)
• Pitch: 0.200" (5.08mm) (fixed requirement)
• Header orientation: 90°, Right Angle (fixed requirement)
• Type: Header, Male Pins, Shrouded (4 Side) (fixed requirement)
• Termination style: Solder (fixed requirement)
• Mounting type: Through Hole (fixed requirement)
• Voltage - IEC: 400 V (fixed requirement)
• Current - IEC: 10A (minimum requirement)
• Voltage - UL: 300 V (fixed requirement)
• Current - UL: 12 A (minimum requirement)
• Material Flammability Rating: UL94 V-0 (fixed requirement)

The substitute part Phoenix Contact 1842380 meets all critical electrical, mechanical, and safety parameters. Variations in housing material (PBT vs. Polyamide), contact tail length, color, and series designation do not affect functional interchangeability within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1842380 is the qualified substitute for the obsolete 5437473. Selection rationale is based on the following factors:

Product Status: The 1842380 maintains active product status with current manufacturing support, whereas the 5437473 is obsolete. This ensures long-term availability and supply chain continuity.

Compliance Certification: Both parts maintain UL94 V-0 material flammability rating and meet IEC electrical specifications. The 1842380 carries ROHS3 compliance, representing current regulatory alignment. Both parts are RoHS compliant.

Electrical Performance: The 1842380 exceeds minimum electrical requirements with 15A UL current rating versus the 12A requirement, providing operational margin. IEC ratings remain equivalent at 10A and 400V.

Mechanical Compatibility: All critical mechanical parameters—position count, pitch, orientation, and mounting type—are identical, ensuring direct form-fit-function replacement in existing PCB designs.

Inventory Availability: The 1842380 demonstrates higher current stock levels (1188 pcs vs. 963 pcs), supporting procurement reliability.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1842380 be used as a direct replacement for the 5437473 in existing designs?

A: Yes. The 1842380 is mechanically and electrically compatible. All critical parameters—8 positions, 4 per level, 0.200" pitch, 90° orientation, and solder termination—are identical. The component will mount directly to existing PCB layouts without modification.

Q: What are the differences between these two parts?

A: The primary differences are: (1) Housing material—5437473 uses Polyamide (PA), while 1842380 uses Polybutylene Terephthalate (PBT); (2) Contact tail length—5437473 is 0.126" (3.20mm), 1842380 is 0.138" (4.60mm); (3) Color—5437473 is gray, 1842380 is green; (4) Series designation—5437473 is BCDH, 1842380 is COMBICON MDSTB; (5) Product status—5437473 is obsolete, 1842380 is active. These differences do not affect electrical or mechanical interchangeability.

Q: Are there any electrical performance differences?

A: The 1842380 provides higher UL current rating (15A vs. 12A), exceeding the minimum requirement. IEC ratings are identical at 10A and 400V. Both parts maintain UL94 V-0 flammability certification.

Q: What is the significance of the contact tail length difference?

A: The contact tail length variation (0.126" vs. 0.138") reflects design differences between series but does not affect PCB mounting compatibility for standard through-hole applications. Verify PCB hole depth if custom or non-standard board specifications exist.

Q: Does the housing material change affect performance?

A: Both materials—Polyamide and Polybutylene Terephthalate—meet UL94 V-0 flammability requirements and are suitable for the specified electrical environment. Material selection reflects series design evolution and does not impact functional performance within stated electrical parameters.

Q: Why is the 1842380 preferred despite the 5437473 being in stock?

A: The 1842380 is active product with ongoing manufacturing support, ensuring future availability and supply chain stability. The 5437473 is obsolete, meaning production has ceased and future procurement may become impossible. For new designs or long-term applications, the active substitute is the appropriate selection.

Q: Are both parts RoHS compliant?

A: Yes. The 5437473 is RoHS Compliant, and the 1842380 is ROHS3 Compliant. Both meet current regulatory requirements for hazardous substance restrictions.
