Phoenix Contact 1704356 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1704356 is a 5-position terminal block header with male pins and partial shroud, designed for 90° right-angle through-hole mounting at 5.00mm pitch. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations. The part operates within IEC ratings of 14.6A at 400V and UL ratings of 10A at 300V, with solder termination and tin-plated contacts.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1704356 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.
• Header Orientation: 90° right-angle configuration is mandatory for form-factor compatibility in space-constrained applications.
• Mounting Type: Through-hole solder termination is required for direct PCB integration without adapter components.
• Electrical Ratings: Substitute parts must meet or exceed the operational voltage and current specifications under both IEC and UL standards.
• Compliance Standards: RoHS compliance and UL94 V-0 flammability rating are essential for regulatory and safety requirements.

The Würth Elektronik 691312710005 qualifies as a functional substitute based on these parameters. While it features a fully shrouded (2-side) design compared to the partial shroud of the original part, it maintains identical position count, pitch, orientation, and mounting methodology. The substitute provides enhanced electrical performance with UL ratings of 20A at 300V and maintains equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The Würth Elektronik 691312710005 is the qualified substitute for the obsolete Phoenix Contact 1704356. Selection rationale is based on the following engineering factors:

Product Status: The Phoenix Contact 1704356 is classified as obsolete, creating supply chain risk. The Würth Elektronik substitute maintains active product status with confirmed inventory availability (1246 pcs), ensuring long-term procurement viability.

Compliance & Certifications: Both parts maintain UL94 V-0 flammability ratings and RoHS compliance. The substitute achieves ROHS3 compliance, representing current regulatory alignment. Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Electrical Performance: The substitute provides superior electrical performance with UL ratings of 20A at 300V, compared to the original 10A at 300V. This enhanced capacity provides design margin for applications operating near the original part's current limits.

Form Factor Compatibility: The substitute maintains identical pitch (5.00mm), position count (5), orientation (90° right angle), and through-hole solder termination. The transition from partial shroud to 2-side shroud design provides improved mechanical stability and contact protection without affecting mating interface compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 691312710005 directly replace the Phoenix Contact 1704356 in existing designs?

A: Yes. Both parts maintain identical pitch (5.00mm), position count (5), header orientation (90° right angle), and solder termination. The substitute's 2-side shroud design provides enhanced contact protection compared to the original partial shroud, with no impact on mating connector compatibility or PCB footprint.

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

A: The primary differences are shroud configuration (partial vs. 2-side), housing material (Polyamide vs. Polybutylene Terephthalate), contact tail length (4.60mm vs. 4.00mm), and electrical ratings (10A vs. 20A UL current). The substitute also specifies operating temperature range (-40°C to 105°C) and contact material (Brass), which are not provided for the original part.

Q: Are there any compatibility concerns with the different shroud designs?

A: No. The shroud design affects only the mechanical housing structure and contact protection. The mating interface—determined by position count, pitch, and pin configuration—remains identical. The 2-side shroud of the substitute provides additional mechanical stability without affecting connector mating.

Q: Does the substitute meet the same compliance requirements?

A: Yes. Both parts maintain UL94 V-0 flammability rating and RoHS compliance. The substitute achieves ROHS3 compliance, representing alignment with current regulatory standards. Both parts carry identical ECCN and HTSUS classifications for export and tariff purposes.

Q: What is the impact of the different contact tail lengths?

A: The substitute features a 0.157" (4.00mm) contact tail compared to the original 0.138" (4.60mm). This difference affects solder joint depth and PCB hole engagement. Verify PCB design specifications to confirm compatibility with the longer contact tail, particularly in applications with specific solder joint requirements or PCB thickness constraints.

Q: Is the higher UL current rating (20A vs. 10A) a concern for existing applications?

A: No. The substitute's higher current rating provides design margin and does not create compatibility issues. Applications designed for the original 10A rating will operate safely with the substitute's 20A capacity. This enhanced rating may benefit designs operating near the original part's current limits.
