Phoenix Contact 1754559 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1754559 is an 8-position terminal block header with male pins, shrouded design, and 5.00mm pitch for 90° right-angle through-hole mounting. This component is classified as Active product status and is designed for solder termination applications requiring IEC-rated 12A at 400V or UL-rated 15A at 300V. Substitute parts are identified when equivalent electrical ratings, mechanical dimensions, and compliance certifications align with the original specification, enabling direct replacement in circuit designs without functional compromise.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Phoenix Contact 1754559 are qualified based on the following critical parameters:

• Electrical Compatibility: Current and voltage ratings must meet or exceed the original specification (IEC 12A/400V or UL 15A/300V)
• Mechanical Compatibility: 8-position configuration, 90° right-angle orientation, through-hole solder termination, and shrouded male pin design
• Pitch Tolerance: Pitch must be 5.00mm (0.197") or 5.08mm (0.200"), as these are mechanically compatible within standard PCB design tolerances
• Compliance: RoHS3 compliance and UL94 V-0 flammability rating required
• Physical Dimensions: Contact tail length and insulation height must be compatible with standard PCB hole spacing and component clearance requirements

Two Würth Elektronik parts meet these criteria: 691312510008 (5.08mm pitch) and 691312710008 (5.00mm pitch).

Parameter Comparison

Engineering Selection Recommendations

Würth Elektronik 691312710008 is the primary substitute for Phoenix Contact 1754559. Both components share identical pitch (5.00mm), contact tail length (4.60mm), and insulation height specifications. The Würth part exceeds the original electrical rating (20A UL vs. 15A UL) and maintains full compliance with RoHS3 and UL94 V-0 standards. Product status is Active for both manufacturers, ensuring long-term availability and supply chain stability.

Würth Elektronik 691312510008 is a secondary substitute suitable for applications where 5.08mm pitch is acceptable within PCB design constraints. This part also provides superior current rating (20A UL) and maintains all required compliance certifications. The 0.08mm pitch difference (5.08mm vs. 5.00mm) requires PCB layout verification to confirm hole spacing compatibility.

Both Würth Elektronik substitutes are manufactured from Polybutylene Terephthalate (PBT) housing material, compared to the original Polyamide (PA) Nylon housing. PBT offers equivalent flammability performance (UL94 V-0) and superior thermal stability across the operating temperature range (-40°C to 105°C).

Frequently Asked Questions (FAQ)

Q: Can Würth Elektronik 691312510008 be used directly on a PCB designed for Phoenix Contact 1754559?

A: Direct substitution requires PCB layout verification. The 0.08mm pitch difference (5.08mm vs. 5.00mm) may exceed hole tolerance stackup on some designs. Confirm that the PCB hole spacing accommodates 5.08mm pitch before implementation.

Q: What is the difference between the two Würth Elektronik substitutes?

A: Both parts share identical electrical ratings (20A UL, 300V UL) and compliance certifications. The primary difference is pitch: 691312510008 uses 5.08mm pitch, while 691312710008 uses 5.00mm pitch (matching the original). Contact tail length differs: 691312510008 is 4.60mm, and 691312710008 is 4.00mm. For direct PCB compatibility, 691312710008 is preferred.

Q: Are the housing material differences between Phoenix Contact and Würth Elektronik significant?

A: Both materials (Polyamide PA and Polybutylene Terephthalate PBT) meet UL94 V-0 flammability requirements. PBT offers superior thermal stability and moisture resistance. Both materials are suitable for the specified operating temperature range (-40°C to 105°C) and environmental conditions.

Q: Do all substitute parts maintain RoHS3 compliance?

A: Yes. Phoenix Contact 1754559 and both Würth Elektronik substitutes (691312510008 and 691312710008) are ROHS3 Compliant, ensuring compatibility with RoHS-regulated supply chains and end-use applications.

Q: What is the current rating difference between the original and substitutes?

A: Phoenix Contact 1754559 is rated 15A (UL) and 12A (IEC). Both Würth Elektronik substitutes are rated 20A (UL), providing 33% higher current capacity. This superior rating does not affect compatibility; the substitutes remain suitable for applications designed for the original 15A/12A specification.
