Phoenix Contact 1704550 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1704550 is a 9-position terminal block header with male pins and partial shroud, designed for 0.197" (5.00mm) pitch vertical through-hole applications. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The part operates at IEC ratings of 14.6A and 400V, with UL ratings of 10A and 300V, and is fully RoHS compliant with UL94 V-0 flammability rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1704550 is determined by the following critical parameters:

• Position Count & Pitch: Both main and substitute parts must maintain 9 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.
• Header Orientation: Vertical orientation is required for through-hole mounting applications.
• Voltage & Current Ratings: The substitute must meet or exceed the electrical requirements. The On-Shore Technology OSTOQ097050 meets the UL voltage rating of 300V, which is the common operational standard between both parts.
• Termination & Mounting: Both parts utilize solder termination and through-hole mounting, ensuring compatibility with standard PCB assembly processes.
• Compliance & Material Standards: RoHS compliance and UL94 V-0 flammability rating are critical for regulated applications.

The On-Shore Technology OSTOQ097050 qualifies as a functional substitute based on matching position count, pitch, orientation, voltage rating, and compliance certifications. Differences in shroud design (partial vs. 2-side shrouded) and contact tail length represent design variations that do not prevent substitution in applications where mechanical clearance permits.

Engineering Selection Recommendations

The On-Shore Technology OSTOQ097050 is the identified substitute for the obsolete Phoenix Contact 1704550 based on matching electrical and mechanical specifications. Selection should be based on the following criteria:

• Product Status: The OSTOQ097050 maintains active product status, ensuring ongoing availability and manufacturer support, whereas the 1704550 is obsolete.
• Compliance Certifications: Both parts maintain RoHS compliance. The OSTOQ097050 carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.
• Electrical Compatibility: Both parts are rated for 300V UL operation, satisfying standard industrial voltage requirements.
• Physical Dimensions: The OSTOQ097050 exhibits different insulation height (0.157" vs. 0.441") and contact tail length (0.157" vs. 0.138"), requiring verification of PCB layout and mating connector clearances before implementation.
• Shroud Configuration: The transition from partial shroud to 2-side shrouded design provides enhanced mechanical protection and may improve connector retention in high-vibration environments.

Frequently Asked Questions (FAQ)

Q: Can the On-Shore Technology OSTOQ097050 directly replace the Phoenix Contact 1704550 in existing designs?

A: Direct replacement is possible if PCB layout accommodates the dimensional differences, specifically the reduced insulation height (0.157" vs. 0.441") and increased contact tail length (0.157" vs. 0.138"). Verification of mating connector compatibility and mechanical clearance is required before implementation.

Q: What is the primary reason for substitution?

A: The Phoenix Contact 1704550 is classified as obsolete. The On-Shore Technology OSTOQ097050 provides an active, functionally equivalent alternative with matching position count, pitch, voltage rating, and compliance certifications.

Q: Are there electrical performance differences between these parts?

A: Both parts are rated for 300V UL operation. The Phoenix Contact 1704550 specifies higher IEC ratings (14.6A at 400V) compared to the On-Shore part, which does not specify IEC current ratings. For applications requiring IEC compliance at 14.6A and 400V, the electrical specifications should be confirmed with the manufacturer.

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

A: The Phoenix Contact 1704550 features a partial shroud, while the OSTOQ097050 has 2-side shrouding. The 2-side shrouded design provides additional mechanical protection and may improve connector alignment and retention. This difference does not affect electrical compatibility but may impact physical installation space requirements.

Q: Are both parts RoHS compliant?

A: Yes. The Phoenix Contact 1704550 is RoHS compliant, and the On-Shore Technology OSTOQ097050 is ROHS3 compliant, meeting current environmental and regulatory standards.
