Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the H12WD4825PGH is determined by the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) topology
• Output Switching Type: AC with zero-cross capability
• Input Control Voltage: 4 – 32 VDC range
• Load Current Rating: 25 A minimum
• Package Mechanical Form: Hockey puck configuration
• Mounting and Termination: Chassis mount with screw terminals
• Compliance Standards: RoHS compliance requirement

The identified substitute part maintains equivalence in circuit type, output switching characteristics, input voltage range, load current capacity, and mechanical packaging. Variations in load voltage operating range do not preclude substitution when the substitute part's voltage range encompasses the application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the H12WD4825PGH and 84138010N are active production components with full RoHS compliance certification. Selection between these parts is determined by load voltage requirements. The H12WD4825PGH operates across a load voltage range of 48 V to 660 V, while the 84138010N operates across 12 V to 270 V. For applications requiring load voltages above 270 V, the H12WD4825PGH is the appropriate selection. For applications operating within the 12 V to 270 V range, either part satisfies the electrical and mechanical requirements. Both components maintain identical input control voltage ranges, load current capacity, circuit topology, and mechanical packaging specifications.
