Procurement Notes

Verify that the specific order matches the 166F6 designation to ensure correct voltage and current ratings. Confirm that the application environment remains within the specified temperature limits. Check lead length requirements against the minimum specification. Ensure compatibility with standard chassis mounting hardware. Review datasheet specifications for any updates regarding compliance standards before finalizing procurement.

Selection Notes

Select this component when a compact, low-power transformer is needed for 115V input systems. The 1.89 VA rating suits light load applications. Consider the open frame design for projects allowing direct airflow cooling. Verify that the 6.3V CT output aligns with downstream circuit requirements. Compare physical footprint constraints against alternative models in the 166 series if space is limited.

Part Context

This transformer belongs to the Hammond 166 series of industrial power transformers. The series offers various power ratings and voltage configurations while maintaining consistent mounting styles. These units are characterized by their robust construction and suitability for general industrial environments. The 166F6 represents a lower power option within this lineup, focusing on efficiency and compactness for specific low-voltage needs.

Replacement Considerations

Consult the manufacturer's official cross-reference list for verified substitutes. Ensure any replacement maintains identical electrical parameters including 1.89 VA rating and 6.3V CT output. Verify mechanical compatibility regarding chassis mounting holes and overall dimensions. Do not assume interchangeability with higher wattage variants without explicit confirmation.
