Procurement Notes

Verify the specific part number suffix against official Hammond Manufacturing documentation to confirm exact electrical ratings and physical specifications. Ensure that the ordering details match the required voltage and current parameters for the intended application. Cross-reference datasheet revisions to confirm compliance with current safety standards and RoHS directives before finalizing procurement orders.

Selection Notes

Select this component when a low voltage, center-tapped secondary output is required for chassis-mounted industrial applications. Consider the 40 VA power rating and 8 A secondary current capacity to ensure adequate load handling. Verify that the 115 VAC primary input matches the available supply voltage and that the physical dimensions fit within the designated enclosure space.

Part Context

The 167R5 belongs to the Hammond Manufacturing 167 Series of general-purpose power transformers. This series offers a wide range of power ratings from 6 VA to over 1600 VA in both open and enclosed styles. The 167 series is widely used in industrial automation and control equipment where reliable voltage transformation and electrical isolation are critical for system operation.

Replacement Considerations

Consult Hammond Manufacturing catalogs for direct replacements within the 167 series or equivalent models from other manufacturers. Verify that substitute parts match the 115 VAC primary, 5 VAC CT secondary, and 40 VA rating. Ensure mechanical mounting hole patterns and lead lengths are compatible with existing assembly requirements.
