Procurement Notes

Verify the specific part number against official Hammond Manufacturing documentation to confirm electrical ratings and physical dimensions. Ensure the application environment supports the specified operating temperature range and frequency requirements. Confirm that the chassis mounting style and wire lead termination method align with the system design constraints before finalizing procurement.

Selection Notes

Select this component when an 8.5VAC center-tapped output is required from a 115VAC source. The 25.5 VA rating dictates the maximum load capacity. Verify that the chassis mounting footprint and wire lead access fit within the enclosure design. Consider the thermal management capabilities required for the +130°C maximum operating temperature specification.

Part Context

The 166M8 belongs to the Hammond 166 series of industrial control transformers. This series provides various power ratings and voltage configurations for general industrial applications. The model utilizes a standard laminated core design common to this product line, ensuring compatibility with typical chassis mounting standards used in industrial equipment manufacturing.

Replacement Considerations

Consult official Hammond Manufacturing cross-reference lists for verified substitute part numbers. Do not assume generic equivalents match the specific 25.5 VA rating or 8.5VAC CT output without verifying datasheet parameters.
