Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1604783 is determined by the following critical parameters that must remain consistent:

• Connector Type & Configuration: Base - Box Mount, Side Entry orientation
• Size Designation: B16 form factor
• Thread Interface: M25 thread size
• Locking Mechanism: Locking Clip (2) on Hood
• Housing Material & Construction: Aluminum, Die Cast
• Electrical & Environmental Compliance: RoHS Compliant, MSL 1
• Operating Temperature Range: -40°C ~ 125°C

The substitute part 1604783 → 1412849 maintains all critical mechanical and electrical parameters while representing an evolution within the Phoenix Contact heavy duty connector product line, transitioning from the HEAVYCON® B series to the HEAVYCON® EVO series with enhanced ingress protection capabilities.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412849 is the direct substitute for the obsolete 1604783. Both components maintain identical mechanical interfaces (B16 size, M25 thread, side entry configuration) and thermal operating specifications (-40°C to 125°C). The substitute part is manufactured by the same original equipment manufacturer and carries equivalent RoHS compliance and MSL ratings.

The 1412849 represents the current active product within the Phoenix Contact heavy duty connector portfolio. Selection of this substitute ensures continued access to genuine Phoenix Contact components with full manufacturer support and documented specifications. The enhanced ingress protection rating (IP66/IP67/IP69K) of the substitute provides additional environmental sealing capability without compromising mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 1412849 directly replace the 1604783 in existing installations?

A: Yes. Both components share identical connector type, size designation (B16), thread interface (M25), locking mechanism, housing material, and operating temperature range. The mechanical mounting and electrical interface specifications are equivalent.

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

A: The 1412849 belongs to the HEAVYCON® EVO series and includes enhanced ingress protection (IP66/IP67/IP69K), whereas the 1604783 from the HEAVYCON® B series does not specify an ingress protection rating. Both maintain the same core mechanical and thermal specifications.

Q: Are there any compliance or certification differences?

A: Both parts are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity level. Both carry the same ECCN (EAR99) and HTSUS (8538.90.8180) classifications.

Q: What is the inventory status of these parts?

A: The 1604783 (obsolete) has 843 pieces in stock. The 1412849 (active) has 943 pieces in stock.

Q: Does the substitute part require any design modifications?

A: No design modifications are required. The dimensional specifications are equivalent within manufacturing tolerances (1604783: 117.00mm L × 57.00mm W × 67.00mm H; 1412849: 117.50mm L × 57.00mm W × 68.00mm H), and all mechanical interfaces remain unchanged.
