Phoenix Contact 1704314 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1704314 is a 3-position terminal block header with male pins and partial shroud, designed for 0.197" (5.00mm) pitch right-angle through-hole mounting. This component operates at 14.6A (IEC) / 10A (UL) and 400V (IEC) / 300V (UL), featuring tin-plated contacts and polyamide housing with UL94 V-0 flammability rating.

The product is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1704314 is determined by the following critical parameters:

• Position Count & Pitch: 3 positions at 0.197" (5.00mm) spacing
• Orientation & Mounting: 90° right-angle through-hole configuration
• Electrical Performance: Current and voltage ratings must meet or exceed IEC 14.6A / 400V
• Contact & Housing Materials: Tin-plated contacts with polyamide or equivalent thermoplastic housing
• Regulatory Compliance: UL94 V-0 flammability rating and RoHS compliance

The Weidmüller 1571140000 qualifies as a functional substitute based on matching position count, pitch, orientation, mounting type, and regulatory certifications. Differences in shroud design (partial vs. full 2-side), housing material (polyamide vs. PBT), and enhanced electrical ratings represent design variations within the same connector category.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1571140000 is a suitable substitute for the obsolete Phoenix Contact 1704314 based on the following engineering criteria:

Electrical Compatibility: The Weidmüller part exceeds the original specifications with 18A (IEC) and 15A (UL) current ratings compared to 14.6A and 10A respectively. Voltage ratings remain equivalent at 400V (IEC) and 300V (UL). This uprating provides margin for existing circuit designs.

Regulatory Compliance: Both components maintain UL94 V-0 flammability classification and RoHS compliance, satisfying regulatory requirements for equivalent product substitution.

Physical & Functional Compatibility: Matching 3-position configuration, 5.00mm pitch, 90° right-angle orientation, and through-hole solder termination ensure mechanical and electrical interchangeability on PCB layouts designed for the original part.

Product Status: The Weidmüller component is active in production, providing long-term supply chain stability compared to the obsolete Phoenix Contact part.

Design Considerations: The Weidmüller 1571140000 features full 2-side shrouding versus partial shroud on the original, and uses PBT housing instead of polyamide. These material and design differences do not affect functional substitution but may require verification if the original design specified partial shroud for specific application constraints.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1571140000 directly replace the Phoenix Contact 1704314 on existing PCBs?

A: Yes. Both components share identical 3-position configuration, 5.00mm pitch, 90° right-angle orientation, and through-hole solder termination. PCB footprints designed for the Phoenix Contact part will accommodate the Weidmüller substitute without modification.

Q: Are there electrical performance differences between these parts?

A: The Weidmüller 1571140000 provides higher current ratings (18A IEC / 15A UL) compared to the Phoenix Contact 1704314 (14.6A IEC / 10A UL). Voltage ratings are equivalent. The higher current capacity of the substitute does not create compatibility issues and provides additional design margin.

Q: What is the significance of the shroud design difference?

A: The Phoenix Contact 1704314 features partial shroud, while the Weidmüller 1571140000 has full 2-side shrouding. This difference affects mechanical protection and mating interface geometry. Applications requiring specific shroud configuration should evaluate this parameter against functional requirements.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both components are UL94 V-0 rated and RoHS compliant, satisfying equivalent regulatory requirements for industrial and commercial applications.

Q: What is the housing material difference, and does it affect substitution?

A: The Phoenix Contact part uses polyamide (PA/nylon) housing, while the Weidmüller part uses polybutylene terephthalate (PBT). Both materials provide UL94 V-0 flammability performance. PBT offers enhanced chemical and thermal resistance. This material difference does not prevent functional substitution.

Q: Is the Weidmüller part available in production quantities?

A: Yes. The Weidmüller 1571140000 is classified as active product status with current inventory availability, providing reliable supply compared to the obsolete Phoenix Contact component.
