Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRF1545CTHC0G is determined by the following critical parameters: diode configuration (1 pair common cathode), technology (Schottky), maximum reverse voltage (45 V), package type (TO-220-3 with isolated tab), mounting method (through hole), and compliance certifications (ROHS3, REACH Unaffected, EAR99).

Substitute parts are grouped into two categories:

Parametric Equivalent: Parts that maintain identical electrical specifications across all key parameters including current rating, forward voltage, reverse leakage, and temperature range. These parts differ only in packaging format (tube versus full pack).

Similar Parts: Parts that share the same diode configuration, technology, reverse voltage, and package type but differ in current rating, forward voltage characteristics, or reverse leakage specifications. These parts are suitable for applications where the lower current rating is acceptable within the design margin.

Parameter Comparison

Engineering Selection Recommendations

MBRF1545CT is the direct parametric equivalent to MBRF1545CTHC0G. Both parts are manufactured by Taiwan Semiconductor Corporation and maintain identical electrical specifications including 15 A current rating, 840 mV forward voltage at 15 A, and 500 µA reverse leakage. The only difference is packaging format: MBRF1545CT is supplied in tube packaging while MBRF1545CTHC0G is supplied in full pack. Both parts are ROHS3 compliant, carry MSL 1 rating, and are active in production. Selection between these two parts depends on procurement and inventory management requirements.

MBRF1545CT-E3/45 is manufactured by Vishay General Semiconductor - Diodes Division and shares the same diode configuration, reverse voltage rating, and package type. However, this part is rated for 7.5 A average rectified current per diode, which is 50% lower than the MBRF1545CTHC0G. The forward voltage is 570 mV at 7.5 A, and reverse leakage is 100 µA at 45 V. This part is suitable for applications where the current requirement does not exceed 7.5 A. Operating temperature range extends to -65°C, providing wider low-temperature capability.

MBRF2545CT-E3/45 is manufactured by Vishay General Semiconductor - Diodes Division and is rated for 12.5 A average rectified current per diode, approximately 83% of the MBRF1545CTHC0G rating. Forward voltage is specified at 820 mV at 30 A, and reverse leakage is 200 µA at 45 V. This part provides a closer current match to the original specification while maintaining the same reverse voltage and package configuration. Operating temperature range extends to -65°C.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and active product status. Selection among these alternatives is based on current capacity requirements within the application design envelope.

Frequently Asked Questions (FAQ)

Q: Can MBRF1545CT be used as a direct replacement for MBRF1545CTHC0G?

A: Yes. MBRF1545CT is a parametric equivalent with identical electrical specifications. The only difference is packaging format: tube versus full pack. Both parts are manufactured by Taiwan Semiconductor Corporation and maintain the same 15 A current rating, 45 V reverse voltage, and 840 mV forward voltage at 15 A.

Q: What is the difference between MBRF1545CT-E3/45 and MBRF1545CTHC0G?

A: MBRF1545CT-E3/45 is rated for 7.5 A average rectified current per diode, compared to 15 A for MBRF1545CTHC0G. Forward voltage is 570 mV at 7.5 A versus 840 mV at 15 A. Reverse leakage is lower at 100 µA. This part is suitable only for applications where current requirements do not exceed 7.5 A.

Q: Can MBRF2545CT-E3/45 replace MBRF1545CTHC0G in a 15 A application?

A: MBRF2545CT-E3/45 is rated for 12.5 A, which is below the 15 A specification of MBRF1545CTHC0G. This part is suitable only for applications where the current requirement is 12.5 A or lower. Applications requiring the full 15 A rating must use MBRF1545CTHC0G or MBRF1545CT.

Q: Are all substitute parts automotive qualified?

A: MBRF1545CTHC0G carries AEC-Q101 automotive qualification. The substitute parts provided do not list AEC-Q101 qualification in the available specifications. Automotive applications requiring AEC-Q101 certification should use MBRF1545CTHC0G or MBRF1545CT.

Q: What is the difference between full pack and tube packaging?

A: Full pack and tube are different packaging formats for the same component. Full pack typically provides protective packaging for individual units, while tube packaging arranges components in a reel or tube format. Both formats contain the same electrical component and are suitable for the same applications. Selection depends on procurement, storage, and assembly process requirements.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All parts listed, including MBRF1545CTHC0G, MBRF1545CT, MBRF1545CT-E3/45, and MBRF2545CT-E3/45, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions.

Q: Are all substitute parts RoHS compliant?

A: Yes. All parts are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for electronic components.

Q: What is the operating temperature range for each part?

A: MBRF1545CTHC0G and MBRF1545CT operate from -55°C to 150°C junction temperature. MBRF1545CT-E3/45 and MBRF2545CT-E3/45 operate from -65°C to 150°C, providing extended low-temperature capability.
