Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the H12WD4875PGH are identified based on functional equivalence within the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A)
• Output type: AC with zero-cross detection
• Input voltage range: 4 – 32 VDC
• Package type: Hockey puck form factor
• Termination: Screw terminal
• Mounting: Chassis mount
• RoHS compliance status

The substitute part 84138150N (Crouzet GN+ series) meets these core functional requirements. Variations in load voltage range (24 V – 500 V versus 48 V – 660 V) and load current rating (90 A versus 75 A) represent the primary technical differences and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the H12WD4875PGH and 84138150N are active production parts with RoHS compliance and unlimited moisture sensitivity ratings. Selection between these parts depends on load voltage and current requirements specific to the application. The H12WD4875PGH supports higher load voltage operation (up to 660 V) with a 75 A current rating. The 84138150N provides higher current capacity (90 A) but operates within a lower load voltage envelope (up to 500 V). Both parts share identical input voltage specifications, circuit topology, and package form factor, ensuring mechanical and electrical interface compatibility within their respective voltage and current operating ranges.

Frequently Asked Questions (FAQ)

Q: Can the 84138150N replace the H12WD4875PGH in all applications?

A: Substitution is valid only when the application load voltage does not exceed 500 V and the required load current does not exceed 90 A. If the application requires operation above 500 V load voltage, the H12WD4875PGH is the appropriate selection.

Q: Are the physical packages identical?

A: Both parts use the hockey puck package form factor with chassis mount configuration and screw terminal termination, ensuring mechanical compatibility in standard mounting applications.

Q: Do both parts support zero-cross switching?

A: Yes, both the H12WD4875PGH and 84138150N incorporate AC zero-cross detection in their output stage, providing identical switching characteristics for AC load control.

Q: What is the input voltage compatibility between these parts?

A: Both parts accept identical input voltage specifications of 4 – 32 VDC, ensuring control circuit compatibility.

Q: Are both parts RoHS compliant?

A: Yes, both the H12WD4875PGH and 84138150N are RoHS compliant with MSL rating 1 (unlimited moisture sensitivity).
