Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1773802 is determined by the following critical parameters:

• Connector Type & Style: Must be Base - Box Mount with Side Entry configuration
• Thread Size: PG21 compatibility is mandatory for mechanical fit
• Operating Temperature Range: Must support -40°C to 125°C minimum
• Housing Material: Aluminum die cast construction
• RoHS Compliance: Required for regulatory alignment
• Ingress Protection: Must meet or exceed IP65 specification

The substitute part 1412863 satisfies all mandatory substitution criteria. While it represents an evolution to the HEAVYCON® EVO series with enhanced IP66/IP67/IP69K protection, it maintains mechanical compatibility through identical thread size (PG21), equivalent operating temperature range, and identical connector type and style configuration.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412863 is a direct functional substitute for the obsolete 1773802. Both components share identical mechanical specifications (PG21 thread, side entry configuration, box mount type) and thermal operating range (-40°C to 125°C). The 1412863 maintains full RoHS compliance and introduces enhanced ingress protection (IP66/IP67/IP69K versus IP65), providing superior environmental sealing without compromising mechanical compatibility.

Selection of the 1412863 is supported by its active product status, ensuring long-term availability and supply chain continuity. The upgrade to the HEAVYCON® EVO series represents a technology advancement within the same connector family, with no mechanical redesign required for integration into existing mounting configurations.

Frequently Asked Questions (FAQ)

Q: Can the 1412863 directly replace the 1773802 in existing installations?

A: Yes. Both components feature identical PG21 thread sizing, side entry configuration, and box mount design. The 1412863 maintains the same locking clip mechanism and operating temperature range, enabling direct mechanical substitution without enclosure modification.

Q: What is the difference between IP65 and IP66/IP67/IP69K protection ratings?

A: The 1773802 provides IP65 protection (dust tight, water resistant). The 1412863 offers enhanced IP66/IP67/IP69K protection (dust tight, water resistant, and waterproof). This represents an improvement in environmental sealing capability suitable for more demanding applications.

Q: Why is the 1773802 listed as obsolete?

A: The 1773802 belongs to the HEAVYCON® HV series, which has been superseded by the HEAVYCON® EVO series. Phoenix Contact has transitioned product lines to the newer EVO generation, making the HV series components obsolete. The 1412863 represents the current active equivalent.

Q: Are there any dimensional differences between these parts?

A: Dimensions are nearly identical. The 1773802 measures 117.00mm L × 57.00mm W × 67.00mm H, while the 1412863 measures 117.50mm L × 57.00mm W × 68.00mm H. These minimal variations do not affect standard PG21 mounting applications.

Q: Does the 1412863 include salt water resistance features?

A: Yes. The 1412863 includes salt water resistant features as part of the HEAVYCON® EVO series enhancement, providing additional corrosion protection in marine and coastal environments compared to the 1773802.
