PT 2,5/ 4-PVH-5,0 BD:25-28 Equivalent & Substitute Parts

Part Overview

The Phoenix Contact PT 2,5/ 4-PVH-5,0 BD:25-28 is a 4-position terminal block plug with female sockets, designed for 0.197" (5.00mm) pitch applications in free-hanging inline configurations. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PT 2,5/ 4-PVH-5,0 BD:25-28 is determined by the following critical parameters:

• Pitch (0.197" / 5.00mm): Must match exactly to ensure mechanical and electrical compatibility with mating connectors
• Number of Positions (4): Functional requirement for circuit configuration
• Type (Plug, Female Sockets): Connector gender and socket configuration must be identical
• Mounting Type (Free Hanging In-Line): Physical installation method must be compatible
• Current Rating (IEC 14.6A minimum): Electrical capacity must meet or exceed the original specification
• Wire Gauge Compatibility (12-20 AWG / 0.5-4mm²): Termination capability must accommodate the specified wire range
• Termination Style (Screw-based): Connection method must be compatible with system requirements

The Würth Elektronik 691385700004 qualifies as a substitute based on matching pitch, position count, connector type, mounting configuration, and screw termination methodology. Electrical ratings exceed the original specification, and wire gauge compatibility overlaps within acceptable parameters.

Parameter Comparison

Engineering Selection Recommendations

The Würth Elektronik 691385700004 is the identified substitute for the obsolete Phoenix Contact PT 2,5/ 4-PVH-5,0 BD:25-28. Selection is based on the following engineering criteria:

Compliance and Status: The substitute part is active in production, ensuring long-term availability and supply chain continuity. Both the original and substitute parts maintain RoHS compliance (RoHS Compliant and ROHS3 Compliant respectively), satisfying environmental regulatory requirements.

Electrical Compatibility: The substitute provides a current rating of 16A (IEC), which exceeds the original 14.6A specification, ensuring adequate electrical capacity for existing circuit designs. Both components are rated for the same pitch and position configuration, guaranteeing mechanical and electrical interface compatibility.

Wire Gauge Considerations: The original part accommodates 12-20 AWG (0.5-4mm²). The substitute accepts 12-24 AWG (0.2-2.5mm²). Wire gauges 12-20 AWG fall within both ranges, ensuring compatibility for standard applications. Applications requiring wire gauges smaller than 0.2mm² or larger than 2.5mm² would require additional evaluation.

Termination Method: Both components utilize screw-based termination, maintaining compatibility with existing wiring practices and installation procedures.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 691385700004 be used as a direct replacement for the Phoenix Contact 1702428?

A: Yes, within the specified wire gauge range of 12-20 AWG (0.5-4mm²). The substitute meets all critical substitution parameters: identical pitch (5.00mm), position count (4), connector type (plug with female sockets), mounting configuration (free hanging inline), and termination method (screw-based). The higher current rating (16A vs. 14.6A) provides additional electrical margin.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Product Status—the original is obsolete while the substitute is active; (2) Wire Gauge Range—the substitute accepts 12-24 AWG versus the original's 12-20 AWG, though overlap exists at 12-20 AWG; (3) Color—green versus gray; (4) Current Rating—16A versus 14.6A; (5) Termination Detail—the original specifies "Screw - Leaf Spring, Wire Guard" while the substitute specifies "Screw." These differences do not prevent substitution for standard applications.

Q: Are there any wire gauge limitations when substituting?

A: Wire gauges 12-20 AWG (0.5-4mm²) are compatible with both parts. The substitute's extended range (12-24 AWG / 0.2-2.5mm²) does not apply to the upper end of the original specification. Applications using wire gauges larger than 2.5mm² would not be compatible with the substitute and would require alternative solutions.

Q: Does the color difference affect functionality?

A: No. Color is a visual identification feature and does not impact electrical or mechanical performance. The color difference (green to gray) is a cosmetic distinction between manufacturers.

Q: What is the packaging difference?

A: The original part number does not specify packaging information. The substitute is supplied in Tray packaging. Verify that tray packaging is compatible with your procurement and assembly processes.
