Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the H12WD4875PG are qualified based on the following critical parameters that determine functional equivalence:

• Circuit Configuration: SPST-NO (1 Form A) topology
• Load Current Rating: 75 A
• Load Voltage Range: 48 V ~ 660 V AC
• Input Control Voltage: 4 ~ 32 VDC
• Output Switching Type: AC with zero-cross detection
• Package Form Factor: Hockey Puck
• Mounting Configuration: Chassis Mount
• Termination Interface: Screw Terminal

The substitute part 84137130N (Crouzet, Series GN) meets all these critical parameters, enabling direct replacement in applications requiring SPST-NO solid state relay functionality with identical electrical ratings and mechanical interface.

Frequently Asked Questions (FAQ)

Q: Can the 84137130N (Crouzet) directly replace the H12WD4875PG (Sensata-Crydom) in existing designs?

A: Yes. Both parts share identical electrical specifications (75 A load current, 48-660 V load voltage, 4-32 VDC input), circuit configuration (SPST-NO with zero-cross AC output), and mechanical form factor (hockey puck, chassis mount, screw terminal). Direct substitution is supported without circuit modification.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution eligibility is determined by matching: circuit topology (SPST-NO), load current rating (75 A), load voltage range (48-660 V AC), control voltage range (4-32 VDC), output switching type (AC zero-cross), package form factor (hockey puck), mounting type (chassis mount), and termination style (screw terminal).

Q: Are there differences in packaging between these parts?

A: The H12WD4875PG is supplied in Bulk packaging, while the 84137130N is supplied in Box packaging. This affects order quantities and storage considerations but does not impact electrical or mechanical performance.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the H12WD4875PG and 84137130N are RoHS Compliant with MSL rating of 1 (Unlimited). Both carry ECCN classification EAR99, supporting equivalent regulatory treatment in most jurisdictions.

Q: What is the difference between the HTSUS codes listed for these parts?

A: The HTSUS codes (8536.49.0080 for H12WD4875PG and 8536.41.0060 for 84137130N) reflect tariff classification differences based on manufacturer categorization. Both codes apply to solid state relay devices and do not indicate functional differences.
