Phoenix Contact 1704385 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1704385 is an 8-position terminal block header with male pins and partial shroud, designed for 90° right-angle through-hole mounting at 5.00mm pitch. This component operates at 14.6A (IEC) / 10A (UL) and 400V (IEC) / 300V (UL), featuring tin-plated contacts and UL94 V-0 rated polyamide housing. The product is classified as obsolete, making equivalent substitutes necessary for ongoing system maintenance and new designs requiring compatible interconnection solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1704385 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Number of positions: 8
• Pitch: 0.197" (5.00mm)
• Header orientation: 90°, Right Angle
• Termination style: Solder
• Mounting type: Through Hole
• Contact tail length: 0.138" (4.60mm)
• Material flammability rating: UL94 V-0

Electrical Compatibility Parameters:

• Voltage rating minimum: 300V (UL standard)
• Current rating minimum: 10A (UL standard)
• Contact mating finish: Tin

The Amphenol Anytek OQ0870510000G satisfies all mandatory matching parameters and electrical compatibility requirements. While the substitute exhibits differences in shroud configuration (2-side shrouded versus partial shroud) and insulation height (0.335" versus 0.441"), these variations remain within acceptable substitution criteria for equivalent terminal block header functionality at the specified electrical ratings.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol Anytek OQ0870510000G is a qualified equivalent substitute for the obsolete Phoenix Contact 1704385. Selection rationale is based on the following engineering factors:

Product Status: The substitute maintains active product status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Compliance & Certifications: Both components meet UL94 V-0 flammability requirements and maintain RoHS compliance. The substitute achieves ROHS3 compliance, representing current regulatory alignment.

Electrical Performance: The substitute exceeds the main part's UL current rating (12A versus 10A) while maintaining identical voltage specifications (300V UL), providing equivalent or superior electrical performance within the same application envelope.

Physical Compatibility: Identical pitch (5.00mm), contact tail length (4.60mm), and through-hole mounting ensure direct mechanical compatibility with existing PCB designs and mating connectors.

Functional Equivalence: Both components provide 8-position solder-terminated headers with tin-plated contacts and UL94 V-0 rated housings, maintaining functional parity for terminal block interconnection applications.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol Anytek OQ0870510000G directly replace the Phoenix Contact 1704385 in existing designs?

A: Yes. Both components share identical pitch (5.00mm), contact tail length (4.60mm), and through-hole mounting specifications. The substitute's 2-side shroud configuration and reduced insulation height (0.335" versus 0.441") do not affect electrical or mechanical compatibility with standard PCB layouts and mating connectors designed for 5.00mm pitch terminal blocks.

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

A: The primary differences are shroud design (partial shroud versus 2-side shrouded), insulation height (0.441" versus 0.335"), housing material (polyamide/nylon versus thermoplastic resin), and product status (obsolete versus active). The substitute provides higher current capacity (12A versus 10A) and current ROHS3 compliance. Electrical ratings at 300V UL remain equivalent.

Q: Are there any electrical performance differences?

A: The Amphenol Anytek substitute exceeds the main part's UL current rating by 2A (12A versus 10A) while maintaining identical 300V voltage specifications. This represents improved electrical performance within the same application class.

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

A: The main part features a partial shroud, while the substitute provides 2-side shrouding. Both configurations maintain UL94 V-0 flammability ratings and do not affect solder-joint reliability or contact performance. The 2-side shroud may provide enhanced mechanical protection during handling and assembly.

Q: Is the substitute suitable for high-reliability applications?

A: Both components meet UL94 V-0 flammability requirements and maintain RoHS compliance. The substitute's active product status and ROHS3 compliance support long-term availability for sustained production environments. Component selection for high-reliability applications should include evaluation of specific application voltage, current, and environmental requirements.
