Phoenix Contact 1704518 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1704518 is a 5-position terminal block header with male pins and partial shroud, designed for 0.197" (5.00mm) pitch vertical through-hole applications. This component operates at 14.6A (IEC) / 10A (UL) and 400V (IEC) / 300V (UL), featuring solder termination and UL94 V-0 flammability rating. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1704518 is determined by the following critical parameters:

• Position Count & Pitch: Substitute parts must maintain 5 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.
• Orientation & Mounting: Vertical through-hole mounting is required for direct form-factor replacement.
• Termination Method: Solder termination is mandatory for compatibility with existing assembly processes.
• Electrical Performance: Substitute parts must meet or exceed the voltage and current ratings specified under both IEC and UL standards.
• Compliance & Safety: RoHS3 compliance and UL94 V-0 flammability rating are required for regulatory and safety equivalence.

The Würth Elektronik 691311700005 qualifies as a functional substitute based on these parameters. While it features a fully shrouded design (versus partial shroud) and operates at higher UL current capacity (20A versus 10A), these represent improvements in electrical performance and mechanical protection. The component maintains identical pitch, position count, vertical orientation, solder termination, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The Würth Elektronik 691311700005 is an active-status substitute for the obsolete Phoenix Contact 1704518. Both components maintain identical electrical specifications under UL standards (300V, with the substitute offering increased current capacity at 20A), equivalent pitch and position geometry, and matching compliance certifications (ROHS3, UL94 V-0, EAR99).

The primary design difference is the shroud configuration: the Phoenix Contact features partial shroud protection, while the Würth Elektronik provides full 2-side shrouding. This represents an enhancement in mechanical protection and contact isolation without compromising electrical or thermal performance.

Both components are tin-plated and suitable for solder termination on through-hole PCB applications. The Würth Elektronik component is currently in active production with documented inventory availability, making it the preferred selection for new designs and obsolescence mitigation strategies.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 691311700005 directly replace the Phoenix Contact 1704518 on existing PCBs?

A: Yes. Both components share identical pitch (5.00mm), position count (5), vertical orientation, and through-hole mounting footprint. The shroud design difference does not affect PCB layout compatibility or mating connector interface.

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

A: The Phoenix Contact 1704518 features partial shroud protection, while the Würth Elektronik 691311700005 provides full 2-side shrouding. The full shroud design offers improved contact isolation and mechanical protection during assembly and operation. This is a functional improvement that does not create compatibility issues.

Q: Are the electrical ratings equivalent?

A: Under UL standards, both components are rated at 300V. The Würth Elektronik substitute is rated at 20A (UL), compared to 10A for the Phoenix Contact. This represents increased current capacity and is suitable for applications requiring the original 10A specification.

Q: Do both components meet the same compliance requirements?

A: Yes. Both are ROHS3 compliant, carry UL94 V-0 flammability rating, and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What is the product status difference, and why does it matter?

A: The Phoenix Contact 1704518 is obsolete, meaning it is no longer manufactured or supported. The Würth Elektronik 691311700005 is active-status, ensuring ongoing availability, technical support, and supply chain reliability for current and future applications.
