MBR1090F-BP Equivalent & Substitute Parts

Part Overview

The MBR1090F-BP is a Schottky rectifier diode rated for 90 V DC reverse voltage and 10 A average rectified current in a through-hole TO-220-2 isolated tab package. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility while meeting current manufacturing and supply chain standards.

Engineering Selection Recommendations

MBR10100F-BP is the primary recommended substitute. This part is manufactured by the same supplier as the original MBR1090F-BP, ensuring design continuity and supply chain consistency. The 100 V rating provides increased voltage margin over the original 90 V specification while maintaining identical forward voltage characteristics and current ratings. Product status is active with confirmed inventory availability. REACH compliance status is unaffected.

DSS10-01A serves as an alternative substitute from IXYS. This part meets all electrical requirements with a 100 V rating and 10 A current capacity. The forward voltage is marginally lower at 840 mV compared to 850 mV, and reverse leakage current is reduced to 300 µA. The operating temperature range extends to 175°C, providing enhanced thermal performance. Product status is active. RoHS3 compliance is confirmed with MSL rating of 1 (Unlimited).

Both substitutes are electrically compatible with the original MBR1090F-BP and support through-hole mounting in TO-220 package configurations. Selection between MBR10100F-BP and DSS10-01A depends on supplier preference, inventory availability, and specific thermal or leakage current requirements of the application.

Frequently Asked Questions (FAQ)

Q: Can MBR10100F-BP directly replace MBR1090F-BP in existing designs?

A: Yes. MBR10100F-BP is electrically compatible with MBR1090F-BP. The 100 V rating exceeds the original 90 V specification, and all other electrical parameters including forward voltage, current rating, and switching speed are identical. Both parts use the TO-220-2 isolated tab package for through-hole mounting.

Q: What is the difference between MBR10100F-BP and DSS10-01A?

A: Both parts meet the core electrical requirements of 10 A current and 100 V reverse voltage. Key differences include: manufacturer (Micro Commercial Co versus IXYS), forward voltage (850 mV versus 840 mV at 10 A), reverse leakage current (500 µA versus 300 µA at 100 V), and operating temperature range (-50°C to 150°C versus -55°C to 175°C). DSS10-01A offers lower leakage and extended temperature performance.

Q: Are there package compatibility concerns when substituting these parts?

A: MBR10100F-BP uses TO-220-2 isolated tab packaging identical to the original MBR1090F-BP. DSS10-01A uses standard TO-220-2 packaging without isolated tab designation. Both are through-hole mounted in TO-220 form factor and are mechanically compatible with standard TO-220 footprints. Verify PCB design accommodates the specific tab configuration if isolation is required.

Q: Why is the MBR1090F-BP classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by the original supplier. MBR10100F-BP and DSS10-01A are active products with current manufacturing and supply availability, making them suitable for new designs and production continuity.

Q: Do the substitute parts meet the same compliance standards?

A: Both MBR10100F-BP and DSS10-01A maintain REACH unaffected status consistent with the original MBR1090F-BP. DSS10-01A additionally carries RoHS3 compliance certification. All parts are classified under ECCN EAR99 and HTSUS 8541.10.0080.
