Engineering Selection Recommendations
The Phoenix Contact 1424846 is the qualified substitute for the obsolete 1775703 based on the following engineering criteria:
Mechanical Compatibility: Both parts share identical connector type, size designation (B32), thread size (PG29), and locking mechanism, ensuring direct functional replacement in box mount applications.
Electrical & Environmental Performance: The substitute maintains the required operating temperature range (-40°C to 125°C) and exceeds the ingress protection requirement, offering IP66/IP67 rating compared to the original IP65 specification. This enhanced protection provides additional environmental durability without compromising compatibility.
Regulatory Compliance: The 1424846 meets current ROHS3 compliance standards and maintains REACH unaffected status, supporting modern procurement and environmental requirements.
Product Lifecycle: The substitute is currently in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete original part.
Physical Dimensions: Minor dimensional increases (1mm length, 12.5mm width, 18mm height) do not affect functional compatibility in standard box mount installations but should be verified against specific enclosure constraints.
Frequently Asked Questions (FAQ)
Q: Can the 1424846 directly replace the 1775703 in existing installations?
A: Yes. Both parts share identical connector type, size (B32), thread size (PG29), and locking mechanism. The substitute is mechanically and electrically compatible for direct replacement in box mount applications.
Q: What is the difference in ingress protection between these parts?
A: The original 1775703 provides IP65 protection (dust tight, water resistant). The substitute 1424846 provides IP66/IP67 protection (dust tight, water resistant, and waterproof). This represents an enhancement in environmental sealing capability.
Q: Are there dimensional differences that affect installation?
A: The 1424846 is slightly larger: 125.00mm L x 94.00mm W x 90.00mm H compared to 124.00mm L x 81.50mm W x 72.00mm H for the 1775703. Verify that the substitute dimensions fit within your enclosure specifications before installation.
Q: Does the substitute meet current compliance standards?
A: Yes. The 1424846 is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The original 1775703 is RoHS compliant but is now obsolete.
Q: What additional features does the substitute provide?
A: The 1424846 includes feed-through capability and salt water resistance, providing enhanced functionality for corrosive or marine environments compared to the original specification.
Q: Is the operating temperature range the same?
A: Yes. Both parts operate across -40°C to 125°C, maintaining thermal performance requirements for the application.
