Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1773844 is determined by the following critical parameters:

• Connector Type & Mounting Style: Base - Box Mount, Side Entry configuration
• Thread Size: PG21 (mechanical interface requirement)
• Operating Temperature Range: -40°C to 125°C minimum
• Housing Material: Aluminum, Die Cast
• RoHS Compliance: Required for regulatory alignment
• Ingress Protection: Minimum IP65 or higher

The substitute part Phoenix Contact 1412857 meets these criteria while offering enhanced specifications in the HEAVYCON® EVO series, including improved ingress protection (IP66/IP67/IP69K) and additional features such as salt water resistance and feed-through capability.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412857 is a direct functional substitute for the 1773844. Both connectors share identical mechanical interfaces (PG21 thread size, side-entry box-mount configuration) and thermal operating ranges (-40°C to 125°C). Both are manufactured from die-cast aluminum and maintain RoHS compliance.

The 1412857 represents an active product in the HEAVYCON® EVO series, ensuring long-term availability and supply chain continuity. The enhanced ingress protection rating (IP66/IP67/IP69K versus IP65) and additional features (salt water resistance, feed-through capability) provide improved environmental performance without compromising mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 1412857 directly replace the 1773844 in existing installations?

A: Yes. Both connectors share identical PG21 thread sizing, side-entry configuration, and box-mount mechanical interface. The 1412857 maintains the same operating temperature range and housing material specifications.

Q: What is the primary difference between these two connectors?

A: The 1412857 offers enhanced ingress protection (IP66/IP67/IP69K) compared to the 1773844 (IP65), includes salt water resistance, and features a feed-through design. Both maintain identical mechanical mounting and thermal performance.

Q: Why is the 1773844 listed as obsolete?

A: The 1773844 belongs to the HEAVYCON® HV series, which has been superseded by the HEAVYCON® EVO series. The 1412857 represents the current-generation equivalent within the active product portfolio.

Q: Are there any packaging differences between these parts?

A: The 1773844 was supplied with standard packaging, while the 1412857 is available in bulk packaging. This does not affect functional or mechanical compatibility.

Q: Do both connectors meet the same regulatory requirements?

A: Yes. Both the 1773844 and 1412857 are RoHS compliant and carry the same ECCN (EAR99) and HTSUS (8538.90.8180) classifications.
