Substitute Part Grouping Explanation

Substitute parts for the MBR1045HC0G are identified based on electrical and mechanical parameter equivalence within the rectifier diode category. The substitution logic is based on the following critical parameters:

Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): 45 V
• Current - Average Rectified (Io): 10 A
• Voltage - Forward (Vf) (Max) @ If: 700 mV @ 10 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 100 µA @ 45 V
• Operating Temperature - Junction: -55°C to 150°C

Mechanical Parameters:

• Package / Case: TO-220-2
• Mounting Type: Through Hole
• Supplier Device Package: TO-220AC

Compliance Parameters:

• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant

Parts meeting all electrical, mechanical, and compliance criteria are classified as direct substitutes. Technology differences (Standard versus Schottky) do not preclude substitution when all specified electrical and mechanical parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

The MBR1045H is a direct substitute for the MBR1045HC0G based on complete electrical and mechanical parameter equivalence. Both components share identical voltage ratings, current ratings, forward voltage characteristics, recovery speed, reverse leakage specifications, and operating temperature ranges. Both are housed in the TO-220AC package for through-hole mounting.

The MBR1045H holds active product status with Taiwan Semiconductor Corporation, ensuring ongoing availability and supply chain continuity. Both components maintain automotive-grade classification with AEC-Q101 qualification, satisfying requirements for automotive applications. Both are ROHS3 compliant and REACH unaffected, meeting regulatory compliance standards.

The technology difference between Standard (MBR1045HC0G) and Schottky (MBR1045H) does not affect substitution eligibility, as all specified electrical performance parameters are identical. The MBR1045H is available in higher inventory quantity (866 Pcs) compared to the discontinued MBR1045HC0G (737 Pcs).

Frequently Asked Questions (FAQ)

Q: Can the MBR1045H be used as a direct replacement for the MBR1045HC0G?

A: Yes. The MBR1045H meets all electrical and mechanical specifications of the MBR1045HC0G. Both components are rated for 45 V DC reverse voltage, 10 A average rectified current, 700 mV forward voltage at 10 A, and operate across the same temperature range (-55°C to 150°C). Both are packaged in TO-220AC for through-hole mounting and hold identical automotive-grade AEC-Q101 qualification.

Q: What is the difference between Standard and Schottky technology in these diodes?

A: The MBR1045HC0G uses Standard technology, while the MBR1045H uses Schottky technology. Both technologies deliver identical electrical performance within the specified parameters provided. The technology designation reflects the internal semiconductor construction but does not alter the functional characteristics relevant to circuit design.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both the MBR1045HC0G and MBR1045H are ROHS3 compliant, REACH unaffected, and hold automotive-grade classification with AEC-Q101 qualification. Both components satisfy identical regulatory and compliance requirements.

Q: Is the TO-220AC package compatible with existing PCB designs for the MBR1045HC0G?

A: Yes. Both components use the TO-220-2 package case with TO-220AC supplier device package designation. The through-hole mounting configuration is identical, ensuring mechanical and electrical compatibility with existing PCB layouts and thermal management designs.

Q: Why is the MBR1045HC0G discontinued while the MBR1045H remains active?

A: Product discontinuation decisions are made by manufacturers based on market demand, production efficiency, and product portfolio optimization. The MBR1045H provides equivalent functionality and remains in active production, ensuring continued availability for applications previously served by the MBR1045HC0G.

Q: What inventory status should be considered when selecting between these parts?

A: The MBR1045H is currently in active production with 866 Pcs available in stock. The MBR1045HC0G, though discontinued, has 737 Pcs remaining in inventory. For new designs and ongoing production, the MBR1045H is the appropriate selection due to its active product status and assured supply continuity.
