Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the HD4825G is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching topology
• Output Type: Must be AC with zero-cross switching to preserve load control characteristics
• Load Current Rating: Must be rated for 25 A minimum
• Load Voltage Range: Must encompass or exceed the 48 V ~ 530 V operating window
• Input Voltage Range: Must accommodate 3 ~ 32 VDC control signals
• Package Type: Must be hockey puck configuration for mechanical fit
• Mounting Type: Must be chassis mount for installation compatibility
• Termination Style: Must use screw terminals for connection compatibility
• Compliance: Must maintain RoHS compliance status

The substitute part 84137110N (Crouzet GN series) meets all these criteria with an extended load voltage range of 48 V ~ 660 V and input voltage range of 4 ~ 32 VDC, both of which encompass the HD4825G specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the HD4825G and 84137110N are active production components with RoHS compliance certification. The HD4825G (Sensata-Crydom) is the primary part with 1114 units in stock. The 84137110N (Crouzet GN series) is the manufacturer-recommended substitute with 1048 units available.

Selection between these parts should be based on:

• Availability: Choose based on current inventory levels and lead time requirements
• Supply Chain Continuity: Either part maintains active production status, ensuring long-term availability
• Regulatory Compliance: Both parts meet RoHS requirements for applications subject to these standards
• Voltage Margin Requirements: The 84137110N provides an extended load voltage ceiling of 660 V compared to 530 V for the HD4825G, offering additional operational margin in high-voltage applications

No technical performance differentiation exists between these parts within their specified operating ranges.

Frequently Asked Questions (FAQ)

Q: Can the 84137110N replace the HD4825G in existing designs?
