Phoenix Contact 1704398 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1704398 is a 9-position terminal block header with male pins and partial shroud, designed for 0.197" (5.00mm) pitch right-angle through-hole applications. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system maintenance and new design implementations. The part operates at IEC-rated 14.6A / 400V and UL-rated 10A / 300V, with tin-plated contacts and polyamide housing rated UL94 V-0.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1704398 is determined by the following critical parameters:

• Position Count & Pitch: 9 positions at 0.197" (5.00mm) spacing
• Orientation & Mounting: 90° right-angle through-hole solder termination
• Electrical Ratings: Minimum IEC 14.6A / 400V or UL 10A / 300V capability
• Contact Configuration: Male pins with shrouding (partial or full acceptable)
• Compliance: RoHS compliance and tin-plated contacts

The On Shore Technology Inc. OSTOQ097051 qualifies as a functional substitute. While it features full shrouding (2-side) rather than partial shroud, it maintains the same 9-position, 5.00mm pitch configuration, right-angle orientation, and solder termination. The OSTOQ097051 meets UL voltage requirements (300V) and operates across -30°C to 105°C, with RoHS3 compliance and tin-plated brass contacts.

Parameter Comparison

Engineering Selection Recommendations

The On Shore Technology OSTOQ097051 is the identified substitute for the obsolete Phoenix Contact 1704398. Selection is justified on the following basis:

• Functional Equivalence: Both components share identical position count (9), pitch (5.00mm), orientation (90° right-angle), and solder termination.
• Electrical Compliance: The OSTOQ097051 meets the UL voltage requirement of 300V specified for the original part.
• Regulatory Status: The OSTOQ097051 holds active product status with ROHS3 compliance, ensuring continued availability and regulatory alignment.
• Contact Specifications: Tin-plated brass contacts in the OSTOQ097051 provide equivalent mating performance to the original tin-plated contacts.

The primary design difference is the transition from partial shroud to full 2-side shrouding. This change enhances mechanical protection and may improve board-level reliability in applications subject to vibration or contamination. PCB layout verification is required to confirm that the increased shroud dimensions do not conflict with existing board routing or component placement.

Frequently Asked Questions (FAQ)

Q: Can the On Shore Technology OSTOQ097051 be used as a direct replacement for the Phoenix Contact 1704398?

A: The OSTOQ097051 is functionally equivalent for applications requiring 9-position, 5.00mm pitch, right-angle solder termination. The transition from partial to full 2-side shrouding requires verification that PCB layout accommodates the increased shroud profile. Electrical ratings and contact specifications are compatible.

Q: What is the key difference between these two parts?

A: The primary difference is shroud configuration. The Phoenix Contact 1704398 features partial shrouding, while the OSTOQ097051 provides full 2-side shrouding. Both maintain identical position count, pitch, orientation, and solder termination. The OSTOQ097051 also specifies an operating temperature range (-30°C to 105°C) not provided for the original part.

Q: Are there compliance or certification concerns with substitution?

A: Both parts are RoHS compliant. The OSTOQ097051 holds ROHS3 certification and is actively manufactured, whereas the Phoenix Contact 1704398 is obsolete. No regulatory barriers exist for substitution in applications meeting UL 300V voltage requirements.

Q: Does the contact tail length difference affect PCB compatibility?

A: The Phoenix Contact 1704398 specifies 0.138" (4.60mm) contact tail length, while the OSTOQ097051 specifies 0.157" (4.00mm). This 0.019" difference requires PCB hole depth verification to ensure adequate solder joint formation. Insulation height also differs (11.20mm vs. 4.00mm), necessitating board clearance confirmation.

Q: What packaging is available for the substitute part?

A: The On Shore Technology OSTOQ097051 is supplied in bulk packaging, with 796 pieces currently in stock as new original inventory.
