Substitute Part Grouping Explanation
Substitution eligibility for the Phoenix Contact 1672783 is determined by the following critical parameters:
Primary Compatibility Criteria:
- Connector Type: Base - Box Mount (fixed requirement)
- Size: D25 (fixed requirement)
- Style: Side Entry (fixed requirement)
- Thread Size: PG16 (fixed requirement)
- Series: HEAVYCON® D (fixed requirement)
- Operating Temperature Range: -40°C to 125°C (fixed requirement)
- Housing Material: Aluminum, Die Cast (fixed requirement)
Secondary Compatibility Criteria:
- Ingress Protection: IP65 minimum (upgrades to IP66/IP67 are acceptable)
- Lock Location: Locking Clip (1) on Base Bottom (fixed requirement)
- RoHS Compliance: Required
The substitute part 1424394 meets all primary and secondary criteria, with an enhanced ingress protection rating (IP66/IP67) that provides superior environmental sealing compared to the original IP65 specification.

Engineering Selection Recommendations
The Phoenix Contact 1424394 is the direct substitute for the obsolete 1672783. Both components share identical mechanical and electrical specifications within the HEAVYCON® D series, maintaining full compatibility for box mount D25 side entry applications with PG16 threading.
The 1424394 offers an operational advantage through enhanced ingress protection (IP66/IP67 versus IP65), providing superior dust and water sealing performance. This upgrade does not compromise any existing system requirements and is suitable for applications requiring extended environmental protection.
Both parts maintain RoHS compliance and operate across the identical temperature range (-40°C to 125°C), ensuring thermal performance equivalence. The 1424394 is currently in active production status, providing supply chain continuity and long-term availability for new installations and replacement applications.
Frequently Asked Questions (FAQ)
Q: Can the 1424394 directly replace the 1672783 in existing installations?
A: Yes. Both connectors share identical mechanical mounting interfaces, D25 sizing, PG16 thread specifications, and locking mechanisms. The 1424394 integrates into existing D25 side entry box mount configurations without modification.
Q: What is the difference between IP65 and IP66/IP67 ratings?
A: IP65 provides dust-tight and water-resistant protection against low-pressure water jets. IP66/IP67 extends protection to high-pressure water jets (IP66) and temporary immersion (IP67). The 1424394's enhanced rating offers superior sealing for applications exposed to washdown environments or splash zones.
Q: Are there any dimensional differences between these parts?
A: The 1424394 has a reduced length (80.00mm versus 109.50mm) and width (51.00mm versus 59.00mm), while maintaining identical height (57.00mm). These dimensional changes do not affect connector functionality or D25 interface compatibility but may require verification of available mounting space in confined installations.
Q: Why is the 1672783 classified as obsolete?
A: Obsolescence reflects Phoenix Contact's product lifecycle management. The 1424394 represents the current production equivalent within the HEAVYCON® D series, offering improved environmental protection specifications.
Q: Are both parts RoHS compliant?
A: Yes. Both the 1672783 and 1424394 meet RoHS compliance requirements, ensuring compatibility with regulatory standards for electrical and electronic equipment.
Q: What is the operating temperature range for both connectors?
A: Both parts operate across -40°C to 125°C, providing identical thermal performance specifications for industrial applications.
