Phoenix Contact 1704534 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1704534 is a 7-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), making it suitable for industrial control and power distribution circuits. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1704534 is determined by the following critical parameters:

• Position Count & Pitch: Both main and substitute parts must maintain 7 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.
• Voltage & Current Ratings: The substitute must meet or exceed the IEC voltage (400V) and current (14.6A) specifications to maintain circuit protection and safety margins.
• Termination Method: Solder termination is required for direct PCB integration without additional adapters.
• Contact Finish & Material: Tin-plated contacts ensure consistent mating performance and corrosion resistance across equivalent parts.
• Compliance Standards: RoHS compliance and MSL rating must be maintained for regulatory and environmental requirements.

The On Shore Technology OSTOQ077050 qualifies as a functional substitute based on matching position count, pitch, voltage rating, solder termination, and compliance certifications. Mechanical differences (shroud configuration and contact tail length) do not prevent substitution when PCB layout accommodates the dimensional variations.

Parameter Comparison

Engineering Selection Recommendations

The On Shore Technology OSTOQ077050 is an active production substitute for the obsolete Phoenix Contact 1704534. Both components meet identical electrical specifications at the UL rating level (300V) and maintain equivalent solder termination compatibility. The OSTOQ077050 carries ROHS3 compliance, exceeding the RoHS Compliant status of the original part, ensuring regulatory alignment with current environmental standards.

Dimensional differences exist in contact tail length (0.157" vs. 0.138") and insulation height (0.157" vs. 0.441"), along with enhanced shroud coverage on the substitute. These mechanical variations require PCB layout verification to confirm clearance and mounting compatibility. The substitute's active production status and improved shroud design provide advantages for new designs and ongoing procurement reliability.

Frequently Asked Questions (FAQ)

Q: Can the OSTOQ077050 directly replace the 1704534 in existing designs?

A: Electrical compatibility is confirmed through matching position count, pitch, voltage rating, and solder termination. Mechanical compatibility requires verification of PCB footprint clearances, particularly regarding the increased insulation height (0.157" vs. 0.441") and enhanced shroud configuration of the substitute.

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

A: The 1704534 features a partial shroud, while the OSTOQ077050 includes 2-side shrouding. Enhanced shrouding improves mechanical stability and contact protection but requires confirmation that the PCB layout and mating connector accommodate the additional material.

Q: Are there current rating differences between these parts?

A: The 1704534 specifies 14.6A (IEC) and 10A (UL). The OSTOQ077050 does not provide IEC current rating data in the available specifications. For applications requiring the full 14.6A IEC rating, the UL 300V specification of both parts should be cross-referenced with application requirements.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS compliant and carry MSL 1 (Unlimited) ratings. The OSTOQ077050 specifically carries ROHS3 compliance and REACH Unaffected status, providing enhanced regulatory documentation for current procurement requirements.

Q: What packaging considerations apply to the substitute?

A: The OSTOQ077050 is supplied in bulk packaging, whereas the original part packaging is not specified. Bulk packaging may require internal reel or tape management for production environments.
