PST 1,3/ 3-LH-5,0 C2 (1704301) Equivalent & Substitute Parts

Part Overview

The Phoenix Contact PST 1,3/ 3-LH-5,0 C2 (Manufacturer Part Number: 1704301) is a 3-position terminal block header with male pins and partial shroud, designed for 90° right-angle through-hole mounting. This component operates at 14.6A (IEC) / 10A (UL) and 400V (IEC) / 300V (UL), with 0.197" (5.00mm) pitch spacing and tin-plated contacts. The product is classified as obsolete, making equivalent substitutes necessary for ongoing applications and new designs requiring compatible functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PST 1,3/ 3-LH-5,0 C2 is determined by the following critical parameters:

• Position Count & Pitch: Substitute parts must maintain 3 positions with 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with existing PCB layouts and mating connectors.
• Orientation & Mounting: 90° right-angle through-hole mounting is required for form-factor compatibility.
• Electrical Ratings: Substitute parts must meet or exceed the IEC current rating of 14.6A and voltage rating of 400V to maintain system safety margins.
• Termination & Compliance: Solder termination, UL94 V-0 flammability rating, and RoHS compliance are mandatory for regulatory and manufacturing process alignment.

The Weidmüller TERM BLOCK HDR 3POS 90DEG 5MM (1571140000) qualifies as a direct substitute based on these parameters. While it features a shrouded (2-side) design versus the partial shroud of the original, it exceeds electrical requirements (18A IEC / 15A UL) and maintains all critical compatibility criteria.

Engineering Selection Recommendations

The Weidmüller 1571140000 is the qualified substitute for the obsolete Phoenix Contact PST 1,3/ 3-LH-5,0 C2. Selection rationale is based on:

• Product Status: The Weidmüller part is active and in production, ensuring long-term availability and supply chain stability compared to the obsolete Phoenix Contact component.
• Regulatory Compliance: Both parts maintain UL94 V-0 flammability rating and RoHS compliance, satisfying regulatory requirements for equivalent applications.
• Electrical Performance: The Weidmüller substitute exceeds the original electrical specifications (18A IEC vs. 14.6A IEC; 15A UL vs. 10A UL), providing enhanced current-carrying capacity without compromising voltage ratings.
• Mechanical Compatibility: Identical pitch (5.00mm), position count (3), and right-angle through-hole mounting ensure direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1571140000 be used as a direct replacement for the Phoenix Contact 1704301?

A: Yes. Both components share identical pitch (5.00mm), position count (3), orientation (90° right-angle), and mounting type (through-hole solder). The Weidmüller part exceeds electrical ratings and maintains equivalent compliance certifications.

Q: What is the primary difference between these two parts?

A: The Phoenix Contact 1704301 features a partial shroud design, while the Weidmüller 1571140000 has a shrouded (2-side) design. This difference does not affect electrical compatibility but may impact mechanical fit in space-constrained applications. Verify clearance in your specific PCB layout.

Q: Are there any compliance or certification differences?

A: Both parts are UL94 V-0 rated and RoHS compliant. The Weidmüller part includes IP20 ingress protection and REACH unaffected status, providing additional environmental protection specifications.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by: 3-position count, 0.197" (5.00mm) pitch, 90° right-angle orientation, through-hole solder termination, minimum 14.6A (IEC) / 10A (UL) current rating, 400V (IEC) / 300V (UL) voltage rating, UL94 V-0 flammability, and RoHS compliance.

Q: Is the higher current rating of the Weidmüller part a concern?

A: No. Higher current ratings indicate enhanced capability and do not create compatibility issues. The substitute will perform safely in applications designed for the original 14.6A (IEC) specification.
