Procurement Notes
Verify the specific part number suffix against official Hammond Manufacturing documentation to ensure correct voltage and wattage ratings. Confirm that the physical mounting dimensions and terminal types match the design requirements. Check RoHS compliance status through the manufacturer's official datasheet or component database before finalizing procurement specifications.
Selection Notes
Select this model when a 115V primary input and 42V center-tapped secondary output are required. Ensure the application load does not exceed the 84 VA rating. Verify that chassis mounting space accommodates the specified length, width, and height. Confirm compatibility with the operating frequency range of 50 Hz or 60 Hz.
Part Context
The 166L42 belongs to the Hammond 166 series of industrial control transformers. This series provides various power ratings and voltage configurations for general-purpose industrial applications. The component is categorized under laminated core power transformers, offering reliable performance for standard electrical isolation and voltage transformation tasks in commercial equipment.
Replacement Considerations
Consult Hammond Manufacturing official cross-reference lists for verified substitute part numbers. Do not assume functional equivalence based solely on similar voltage ratings without verifying current capacity and physical dimensions.
