Frequently Asked Questions (FAQ)

Q: Can MBR16100CTG be used as a direct replacement for MBR16100CT?

A: Yes. MBR16100CTG is electrically and mechanically identical to MBR16100CT, with matching 100 V reverse voltage, 8 A current rating, and TO-220-3 package. Both parts are classified as obsolete. MBR16100CTG offers improved RoHS3 compliance status.

Q: What is the primary reason to substitute the MBR16100CT?

A: The MBR16100CT is classified as obsolete. Substitution is necessary to ensure continued component availability for new production and maintenance applications.

Q: Can I use a higher current-rated substitute such as STPS40SM100CT or SDT30A100CT?

A: Yes. Substitutes with current ratings exceeding 8 A (such as 15 A or 20 A) are electrically compatible when the 100 V reverse voltage, Schottky technology, 1 Pair Common Cathode configuration, and TO-220-3 package are maintained. Higher current ratings provide design margin and do not compromise circuit function in applications requiring 8 A or less.

Q: Are all substitute parts RoHS compliant?

A: MBR16100CTG, 16CTQ100, SDT30A100CT, STPS40SM100CT, and VS-16CTQ100-M3 are all RoHS3 Compliant. The original MBR16100CT is RoHS non-compliant. Compliance status should be verified against specific procurement requirements.

Q: What is the difference between MBR16100CT and MBR16100CT-BP?

A: MBR16100CT-BP is rated for 16 A per diode compared to 8 A for MBR16100CT. Both maintain 100 V reverse voltage and TO-220-3 package. MBR16100CT-BP is manufactured by Micro Commercial Co and has active product status. Forward voltage at 8 A is 850 mV for MBR16100CT-BP versus 740 mV for MBR16100CT.

Q: Does package format differ among substitute parts?

A: All substitute parts use the TO-220-3 package format, ensuring mechanical and thermal compatibility. Supplier device package designations may vary (TO-220, TO-220AB, TO-220-3) but all conform to the same physical TO-220-3 standard.

Q: Which substitute offers the best reverse leakage performance?

A: STPS40SM100CT exhibits the lowest reverse leakage at 45 µA @ 100 V, compared to 100 µA @ 100 V for the original MBR16100CT. This represents superior leakage characteristics and may be advantageous in low-power or precision applications.

Q: Can VS-16CTQ100-M3 operate across the full temperature range of the original MBR16100CT?

A: Yes. VS-16CTQ100-M3 has a maximum junction temperature of 175°C, matching the original part's upper operating limit. The minimum operating temperature is -55°C, which is higher than the original -65°C specification but suitable for most industrial and commercial applications.
