Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HD4875-10 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) topology
• Load Current Rating: Must be rated for 75A continuous operation
• Output Type: Must be AC output
• Package Form Factor: Must be hockey puck configuration
• Termination: Must use screw terminal connections
• Mounting: Must support chassis mount installation
• Voltage Compatibility: Input voltage range must overlap with 3 ~ 32VDC; load voltage range must encompass or extend the 48V ~ 530V specification

The substitute part 84137330N (Crouzet GN series) meets these criteria with compatible electrical specifications and identical mechanical packaging.

Parameter Comparison

Engineering Selection Recommendations

Both the HD4875-10 and 84137330N are active products with current manufacturing status. The HD4875-10 carries ROHS3 compliance and is REACH Affected. The 84137330N carries RoHS compliance and is REACH Unaffected, which may provide regulatory advantages in certain supply chain contexts.

The load voltage specification of 84137330N extends to 660V compared to the HD4875-10 specification of 530V, providing additional operational margin in high-voltage applications. The input voltage specification of 84137330N begins at 4VDC versus 3VDC for the HD4875-10, representing a minor constraint in low-voltage control circuits.

Selection between these parts should be based on specific application voltage requirements, regulatory compliance obligations, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the 84137330N replace the HD4875-10 in all applications?

A: Substitution is valid when the application load voltage does not fall below 48V and does not exceed 530V, and when the control input voltage is 4VDC or higher. The 84137330N's extended load voltage range (up to 660V) does not create incompatibility in applications designed for the HD4875-10's 530V maximum.

Q: What is the significance of the hockey puck package form factor?

A: The hockey puck configuration is a specific mechanical and thermal package design for solid state relays. Both parts use this identical form factor, ensuring mechanical interchangeability in chassis mount applications with screw terminal connections.

Q: How do the RoHS and REACH compliance differences affect substitution?

A: RoHS and REACH compliance are regulatory certifications that affect supply chain eligibility and end-market applicability. The HD4875-10 is ROHS3 Compliant and REACH Affected; the 84137330N is RoHS Compliant and REACH Unaffected. Selection depends on the regulatory requirements of the end application and target markets.

Q: Are there input voltage constraints when substituting?

A: The 84137330N input voltage range begins at 4VDC, while the HD4875-10 begins at 3VDC. Applications requiring control signals below 4VDC cannot use the 84137330N as a substitute.

Q: Do both parts have the same load current rating?

A: Yes. Both the HD4875-10 and 84137330N are rated for 75A continuous load current in SPST-NO configuration with AC output.
