Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1704327 is determined by the following critical parameters:

• Position Count & Pitch: 4 positions at 0.197" (5.00mm) spacing
• Orientation & Mounting: 90° right-angle configuration with through-hole or solder mounting capability
• Electrical Performance: Minimum voltage rating of 300V (UL) and current handling of 10A (UL)
• Contact Configuration: Male pins with tin mating finish
• Compliance: RoHS compliance and UL94 V-0 flammability rating
• Physical Dimensions: Contact tail length and insulation height within acceptable tolerance ranges

The On Shore Technology Inc. OSTOQ047051 qualifies as a functional substitute based on matching position count, pitch, orientation, voltage rating, contact finish, and compliance certifications. Differences in shroud design (2-side shrouded versus partial shroud) and contact tail length represent acceptable variations within the terminal block header category.

Parameter Comparison

Engineering Selection Recommendations

The On Shore Technology OSTOQ047051 serves as the primary substitute for the obsolete Phoenix Contact 1704327. Both components maintain identical position count, pitch, orientation, and UL voltage rating of 300V, ensuring electrical compatibility in standard applications.

The OSTOQ047051 holds active product status with ROHS3 compliance, providing supply chain continuity and regulatory alignment for new designs and ongoing production. The component's tin contact mating finish matches the original specification, supporting equivalent electrical performance.

Physical dimension variations—specifically the increased contact tail length (0.157" versus 0.138") and reduced insulation height (0.157" versus 0.441")—require PCB layout verification to confirm mechanical fit within existing mounting patterns. These differences do not affect electrical function but necessitate design review for through-hole spacing and clearance validation.

Frequently Asked Questions (FAQ)

Q: Can the OSTOQ047051 directly replace the Phoenix Contact 1704327 in existing designs?

A: Electrical compatibility is confirmed through matching position count, pitch, voltage rating, and contact finish. Mechanical compatibility requires verification of PCB hole spacing and component clearance, as the substitute exhibits different physical dimensions.

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

A: The Phoenix Contact 1704327 features a partial shroud, while the OSTOQ047051 is shrouded on two sides. Both configurations provide adequate insulation and contact protection for standard terminal block applications. The shroud design does not affect electrical performance or pitch compatibility.

Q: Are there compliance differences between the two parts?

A: Both components are RoHS compliant. The Phoenix Contact 1704327 is RoHS Compliant, and the OSTOQ047051 is ROHS3 Compliant, representing an updated compliance standard. Both meet regulatory requirements for electronic component manufacturing.

Q: What mounting method differences exist?

A: The Phoenix Contact 1704327 is specified for through-hole mounting, while the OSTOQ047051 is specified for solder mounting. Both methods achieve equivalent mechanical and electrical connection to PCBs. Design verification is required to confirm compatibility with existing assembly processes.

Q: Is the operating temperature range a limiting factor?

A: The OSTOQ047051 specifies an operating temperature range of -30°C to 105°C. The Phoenix Contact 1704327 does not provide an operating temperature specification in available documentation. For applications requiring temperature performance confirmation, the OSTOQ047051 range provides defined thermal operating limits.
