Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B485H-2 is determined by the following critical parameters:

• Diode Type: Single Phase configuration
• Voltage Rating: 1.6 kV peak reverse voltage (maximum)
• Current Rating: 50 A average rectified current (Io)
• Forward Voltage: 1.35 V @ 50 A (maximum)
• Temperature Range: -40°C ~ 125°C (TJ)
• Mounting Interface: QC Terminal
• Package Form: B48 Module
• Regulatory Compliance: RoHS Compliant

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. The B485H-2T satisfies all specified criteria and shares the same base product number (B485H), confirming functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The B485H-2T is the direct parametric equivalent for the B485H-2. Both parts are manufactured by Sensata-Crydom and maintain identical electrical and mechanical specifications across all critical parameters. The B485H-2T carries active product status, ensuring ongoing availability and supply chain support. Both parts maintain RoHS compliance and equivalent regulatory certifications (ECCN: EAR99; HTSUS: 8541.10.0080).

For applications currently using the B485H-2, transition to the B485H-2T provides equivalent performance with improved supply continuity. No circuit redesign or thermal management modifications are required.

Frequently Asked Questions (FAQ)

Q: Can the B485H-2T directly replace the B485H-2 in existing designs?

A: Yes. The B485H-2T is a parametric equivalent with identical electrical ratings (1.6 kV, 50 A), forward voltage characteristics (1.35 V @ 50 A), operating temperature range (-40°C ~ 125°C), and mechanical interface (QC Terminal, B48 Module). No circuit modifications are necessary.
