Procurement Notes

Verify the specific secondary voltage and current requirements against the 166F5 datasheet before ordering. Confirm that the chassis mounting style and wire lead terminations match the design constraints. Ensure the operating environment stays within the specified temperature limits. Check for any regional shipping restrictions or RoHS compliance documentation needs prior to finalizing the purchase order.

Selection Notes

Select this component when a compact, low-voltage transformer is needed for chassis integration. Compare the 8 VA rating against the total load requirements of the downstream circuitry. Consider the physical dimensions relative to available panel space. Evaluate the 115 VAC input compatibility with the local power distribution system. Review thermal management options given the high maximum operating temperature.

Part Context

This part belongs to the Hammond 166 series of industrial control transformers. The series offers various voltage and wattage combinations for different applications. The 166F5 specifically addresses low-power, low-voltage needs. It shares common mounting and termination characteristics with other models in the family, facilitating standardized enclosure designs.

Replacement Considerations

Direct substitutes may include other Hammond 166 series models with matching electrical ratings. Verify that alternative parts maintain the same chassis mount style and wire lead configuration. Cross-reference dimensions to ensure fit within existing enclosures. Confirm that the replacement meets the same safety and environmental standards.
