Substitute Part Grouping Explanation

Substitute parts for the H12WD4850-10 are identified through direct equivalence of critical electrical and mechanical parameters. The substitution logic is based on the following matching criteria:

• Circuit Configuration: SPST-NO (1 Form A) topology
• Load Specifications: 50A capacity at 48V to 660V AC
• Control Input: 4V to 32V DC
• Package Form Factor: Hockey puck chassis mount configuration
• Termination: Screw terminal interface

The Crouzet 84137320N meets all specified parameters and is classified as a manufacturer-recommended substitute. Both parts share identical electrical ratings and mechanical mounting characteristics, enabling direct replacement without circuit modification.

Parameter Comparison

Engineering Selection Recommendations

Both the H12WD4850-10 and 84137320N are Active products suitable for new designs and ongoing production applications. The H12WD4850-10 carries RoHS3 compliance, while the 84137320N is RoHS compliant. Both components are REACH affected or unaffected respectively, with EAR99 export classification. Selection between these parts should be based on supply chain availability, packaging requirements (Bulk versus Box), and compliance certifications applicable to the end application. The electrical and mechanical equivalence ensures functional interchangeability without design modification.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 84137320N directly replace the Sensata-Crydom H12WD4850-10 in existing applications?

A: Yes. Both parts share identical electrical ratings (50A, 4-32VDC control, 48-660V AC load), circuit configuration (SPST-NO), and mechanical form factor (hockey puck, screw terminal, chassis mount). Direct substitution is supported without circuit redesign.

Q: What are the key parameters that determine substitution compatibility?

A: Load current (50A), input voltage range (4-32VDC), output voltage range (48-660V AC), circuit topology (SPST-NO 1 Form A), package type (hockey puck), and termination style (screw terminal) are the critical parameters. Matching these specifications ensures functional equivalence.

Q: Are there differences in packaging between these parts?

A: The H12WD4850-10 is supplied in Bulk packaging, while the 84137320N is supplied in Box packaging. This distinction affects order quantities and storage but does not impact electrical or mechanical performance.

Q: Do both parts meet current compliance requirements?

A: Both parts are Active products with current RoHS compliance. The H12WD4850-10 is RoHS3 compliant, and the 84137320N is RoHS compliant. Both carry EAR99 export classification. Verify REACH status requirements for your specific application region.

Q: What is the moisture sensitivity level for these components?

A: The H12WD4850-10 has MSL Not Applicable. The 84137320N has MSL 1 (Unlimited). Both ratings indicate minimal moisture sensitivity concerns for standard handling and storage.
