Substitute Part Grouping Explanation

Substitution of the CD2425D3VH is based on electrical and mechanical parameter equivalence within the Sensata-Crydom Evolution Dual series. The following parameters define acceptable substitutes:

• Circuit configuration: SPST-NO (1 Form A) x 2 (dual channel)
• Output type: AC with zero-cross switching
• Input voltage range: 4 ~ 15VDC
• Load voltage range: 24 V ~ 280 V
• Load current rating: 25 A
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Package type: Hockey Puck

The CD2425D4VH meets all these criteria and is identified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The CD2425D4VH is the direct substitute for the CD2425D3VH. Both components share identical electrical specifications and mechanical form factors. The primary distinction is product status: the CD2425D3VH is obsolete while the CD2425D4VH is active. The CD2425D4VH carries RoHS Compliant certification, meeting current environmental compliance requirements. Both components are classified under ECCN EAR99 and HTSUS 8536.41.0060. Selection of the CD2425D4VH ensures access to an actively supported component with equivalent performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the CD2425D4VH directly replace the CD2425D3VH in existing applications?

A: Yes. The CD2425D4VH is electrically and mechanically equivalent to the CD2425D3VH. Both components feature identical input voltage range (4–15VDC), load voltage range (24–280V), load current rating (25A), circuit configuration (dual SPST-NO), output type (AC zero-cross), mounting type (chassis mount), termination style (screw terminal), and package type (hockey puck).

Q: What is the primary reason for substitution?

A: The CD2425D3VH is obsolete. The CD2425D4VH is the active equivalent from the same manufacturer and series, ensuring continued component availability and supply chain continuity.

Q: Are there any compliance differences between these parts?

A: The CD2425D4VH is RoHS Compliant, while RoHS status is not specified for the CD2425D3VH. Both components share the same ECCN (EAR99) and HTSUS (8536.41.0060) classifications.

Q: Will the hockey puck package dimensions remain the same?

A: Yes. Both the CD2425D3VH and CD2425D4VH use the hockey puck package type with chassis mount configuration, ensuring mechanical compatibility in existing installations.

Q: Are the screw terminal connections identical?

A: Yes. Both components use screw terminal termination style, maintaining electrical connection compatibility.
