Power Transformers Procurement Notes

This component is officially discontinued and no longer manufactured by Tamura. Procurement must focus on verified direct replacement parts rather than original stock. Verify that substitute components match the required electrical ratings and physical footprint before integration. Ensure all replacement units meet current safety standards and isolation requirements for the target application environment.

Power Transformers Selection Notes

Selection should prioritize direct replacements due to the part's obsolescence. Evaluate alternative transformers based on identical VA rating, voltage configurations, and mechanical dimensions. Confirm that the substitute maintains the necessary isolation voltage and thermal performance. Cross-reference datasheets to ensure pinout compatibility and mounting hole alignment for seamless PCB integration without redesign.

Power Transformers Part Context

The PF24-34 belongs to the Tamura PF24 series of semi-toroidal power transformers. This series is designed for board-mounted applications requiring reliable power conversion. The specific model provides versatile secondary outputs suitable for various rectification needs. As a legacy component, it represents standard industrial power transformation technology prior to modern surface-mount trends.

Power Transformers Replacement Considerations

The LP-34-700 from Signal Transformer is a confirmed direct substitute. Verify that this replacement matches the 24VA rating and secondary voltage/current specifications. Ensure physical dimensions and mounting type are compatible with the existing PCB layout.
