Procurement Notes
Verify part status carefully as this item is listed as obsolete or discontinued by major distributors. Confirm availability through authorized channels or secondary markets. Ensure the specific encapsulation type matches original design requirements. Cross-reference pinout and inductance values against current schematics before procurement to avoid integration errors.
Selection Notes
Select this component only when SCR or Triac triggering via pulse transformation is required. The fixed 6.6mH inductance dictates its suitability for specific timing characteristics. Chassis mounting constraints must be accommodated in the mechanical design. Consider the physical dimensions of 2.060 inches length when planning layout space.
Part Context
This unit is part of the Hammond Manufacturing 612 series, which specializes in pulse transformers for thyristor applications. The series typically offers encapsulated options for environmental protection. Hammond Manufacturing is recognized for producing industrial enclosures and electronic components, including various transformer types for power management.
Replacement Considerations
The 616G is noted as a discontinued alternative solution. Contact Hammond Manufacturing directly for assistance with alternative solutions or modern equivalents. Verify electrical compatibility and mechanical fit before substituting with other pulse transformers.
