167N10

Overview

The Hammond Manufacturing 167N10 is an obsolete industrial power transformer featuring a laminated core and chassis mount design. It provides a single primary winding rated for 115 VAC input and a single secondary winding delivering 10 VAC center-tapped output at 4 A. The unit has a maximum power rating of 56 VA, with dimensions of 63.50 mm in length, 69.85 mm in width, and 77.72 mm in height. Termination is achieved via wire leads.

Feature Summary

• Enclosed chassis mount construction with wire lead termination
• Single primary and single secondary winding configuration
• Laminated core design for standard industrial applications

Applications

• Industrial control panels requiring low voltage AC power
• Equipment utilizing filament or pilot lamp circuits
• Chassis-mounted power supply units

Procurement Notes

This component is officially discontinued and no longer manufactured by Hammond Manufacturing. Procurement must focus on identifying verified substitute part numbers from other manufacturers that match the electrical specifications and physical footprint. Direct sourcing from the original manufacturer is not possible due to end-of-life status.

Selection Notes

Designers should prioritize replacement components that maintain the 56 VA power rating, 115 VAC primary input, and 10 VAC CT secondary output. Physical compatibility requires matching the chassis mount style and terminal type. Verify that alternative transformers meet the same isolation and thermal requirements for the intended enclosure environment.

Part Context

The 167N10 belongs to the Hammond 167 series of industrial control transformers. This series typically offers enclosed, chassis-mountable units designed for reliable operation in various industrial environments. The specific model represents a lower-power variant within this family, characterized by its compact laminated core structure.

Replacement Considerations

Triad Magnetics F-252U is documented as a similar substitute part number.
