Key Parameters

Substitute Part Grouping Explanation

Substitution of the B485C-2T is determined by strict equivalence across the following critical parameters:

• Diode Type: Single Phase
• Technology: Standard
• Voltage - Peak Reverse (Max): 600 V
• Current - Average Rectified (Io): 50 A
• Voltage - Forward (Vf) (Max) @ If: 1.35 V @ 50 A
• Operating Temperature Range: -40°C ~ 125°C (TJ)
• Mounting Type: QC Terminal
• Package / Case: B48 Module

The B485C-2 meets all these parameters and is manufactured by the same supplier (Sensata-Crydom), making it a parametric equivalent. The primary distinction is product status: B485C-2T is obsolete, while B485C-2 is active.

Parameter Comparison

Engineering Selection Recommendations

The B485C-2 is the direct parametric equivalent for the obsolete B485C-2T. Both components share identical electrical and mechanical specifications, including voltage rating, current capacity, forward voltage characteristics, and thermal operating range. The B485C-2 is currently in active production status, ensuring availability for replacement and new applications.

The B485C-2 carries ROHS3 compliance and REACH Affected status, indicating adherence to current environmental and regulatory standards. The B485C-2T's REACH Unaffected status reflects its obsolete classification. For new designs or system upgrades, the B485C-2 is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can B485C-2 directly replace B485C-2T in existing applications?

A: Yes. Both components are parametrically identical across all critical electrical and mechanical parameters: 600V peak reverse voltage, 50A average rectified current, 1.35V forward voltage at 50A, -40°C to 125°C operating temperature range, QC terminal mounting, and B48 module package. No circuit modifications are required.

Q: What is the difference between B485C-2T and B485C-2?

A: The primary difference is product status. B485C-2T is obsolete, while B485C-2 is active. Additionally, B485C-2 is ROHS3 compliant and REACH Affected, reflecting current manufacturing and regulatory standards. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: No. Both components use the B48 module package with QC terminal mounting. Packaging is identical, ensuring mechanical compatibility in existing designs.

Q: What does "parametric equivalent" mean in this context?

A: Parametric equivalence means the components share identical values across all specified electrical parameters (voltage, current, forward voltage, temperature range) and mechanical characteristics (package type, mounting method). This equivalence ensures functional interchangeability in circuit applications.

Q: Why is B485C-2T classified as obsolete?

A: Product obsolescence is determined by manufacturer discontinuation. B485C-2T has been discontinued and replaced by B485C-2, which maintains identical specifications while meeting current regulatory and compliance requirements.
