Parameter Comparison

Engineering Selection Recommendations

STPS20H100CFP (STMicroelectronics) is the primary substitute for the MBRF20H100CTH. This part maintains complete electrical and mechanical equivalence across all specified parameters. The STPS20H100CFP carries Active product status, ensuring long-term availability and supply chain support. The component is ROHS3 Compliant and REACH Unaffected, meeting regulatory requirements identical to the original part. Inventory availability is substantial at 105,100 pieces.

MBRF20H100CT-E3/45 (Vishay General Semiconductor - Diodes Division) is a secondary substitute option. This part is electrically equivalent and shares the same base product number (MBRF20) as the original component. The primary distinction is the isolated tab variant of the TO-220-3 Full Pack package (ITO-220AB), which provides electrical isolation of the tab from the die. This variant is suitable for applications requiring isolated mounting or thermal management configurations that benefit from tab isolation. The part carries Active product status, ROHS3 Compliance, and REACH Unaffected status. Inventory availability is 1,400 pieces.

Both substitute parts are qualified for direct replacement based on electrical performance, thermal characteristics, and regulatory compliance. Selection between the two substitutes depends on specific application requirements regarding package isolation and supply chain preferences.

Frequently Asked Questions (FAQ)

Q: Can the STPS20H100CFP directly replace the MBRF20H100CTH in existing designs?

A: Yes. The STPS20H100CFP maintains electrical equivalence across all specified parameters including reverse voltage rating (100 V), average rectified current (10 A per diode), forward voltage drop (770 mV @ 10 A), reverse leakage current (4.5 µA @ 100 V), and thermal characteristics (175°C maximum junction temperature). The TO-220-3 Full Pack package is mechanically compatible with existing PCB layouts and thermal management solutions.

Q: What is the difference between the STPS20H100CFP and MBRF20H100CT-E3/45?

A: Both parts are electrically equivalent. The primary difference is the package variant. The STPS20H100CFP uses a standard TO-220-3 Full Pack, while the MBRF20H100CT-E3/45 uses an isolated tab variant (ITO-220AB). The isolated tab provides electrical isolation of the mounting tab from the semiconductor die, which is beneficial in applications requiring isolated mounting or specific thermal management configurations.

Q: Are there any compliance or regulatory differences between the substitute parts and the original MBRF20H100CTH?

A: No. All three parts are ROHS3 Compliant and REACH Unaffected. Regulatory compliance is equivalent across the original and substitute components.

Q: What is the significance of the MBRF20H100CTH being classified as Obsolete?

A: Obsolete status indicates that the original manufacturer (onsemi) has discontinued production and support for this part. The identified substitute parts carry Active status, meaning they are currently in production and supported by their respective manufacturers, ensuring long-term availability and supply chain continuity.

Q: Which substitute part should be selected for new designs?

A: The STPS20H100CFP is recommended for new designs due to its Active product status, substantial inventory availability (105,100 pieces), and direct electrical and mechanical equivalence. The MBRF20H100CT-E3/45 is suitable when isolated tab functionality is required by the application.

Q: Are the forward voltage characteristics identical across all three parts?

A: Yes. All three parts specify a maximum forward voltage of 770 mV at 10 A forward current, ensuring equivalent performance in rectification and switching applications.

Q: What is the reverse leakage current specification for these diode arrays?

A: All three parts specify a maximum reverse leakage current of 4.5 µA at the maximum reverse voltage rating of 100 V, indicating equivalent leakage performance across the product range.
