Engineering Selection Recommendations

Direct Substitutes (Preferred for Obsolete Part Replacement):

SCS210KGC17 (Rohm Semiconductor) is the primary direct substitute. This part maintains identical electrical specifications to the main part including 1200 V reverse voltage, 10 A current rating, 1.6 V forward voltage at 10 A, and 0 ns reverse recovery time. The part is Active status with higher inventory availability (10100 units). Both parts are ROHS3 compliant and REACH unaffected. The supplier device package designation differs (TO-220ACFP versus TO-220AC), but both conform to the TO-220-2 case family.

UJ3D1210TS (Qorvo) is a secondary direct substitute meeting all primary electrical criteria with 1200 V, 10 A, 1.6 V forward voltage, and 0 ns recovery time. This part is Active status with 10136 units in inventory. Operating temperature range extends to -55°C minimum, providing broader thermal coverage. ROHS3 compliant and REACH unaffected.

Similar Substitutes (Acceptable for Current-Rated Applications):

FFSP10120A (onsemi) meets the 1200 V and 10 A requirements with slightly elevated forward voltage (1.75 V @ 10 A) and recovery time specification (≤ 500 ns). This part is Active status with 3556 units available. ROHS3 compliant and REACH unaffected. Operating temperature range is -55°C to 175°C.

SICR101200 (SMC Diode Solutions) meets the 1200 V and 10 A requirements with 1.8 V forward voltage and 0 ns recovery time. This part is Active status with limited inventory (750 units). ROHS3 compliant but REACH affected. Operating temperature range is -55°C to 175°C.

Reduced Current Rating Substitute (Not Recommended for Direct Replacement):

IDH05G120C5XKSA1 (Infineon Technologies) is rated for 5 A average rectified current, which is 50% of the main part specification. This part is suitable only for applications with reduced current requirements. It offers superior reverse leakage characteristics (33 µA @ 1200 V) and lower capacitance (301 pF). Active status with 4099 units in inventory. ROHS3 compliant and REACH unaffected.

Frequently Asked Questions (FAQ)

Q: Can SCS210KGC17 be used as a direct replacement for SCS210KGC?

A: Yes. SCS210KGC17 is a direct substitute with identical electrical specifications: 1200 V reverse voltage, 10 A current rating, 1.6 V forward voltage at 10 A, and 0 ns reverse recovery time. Both parts use TO-220-2 package family. The main difference is product status (Active versus Obsolete) and supplier device package designation. SCS210KGC17 has higher inventory availability.

Q: What is the difference between TO-220AC and TO-220ACFP package designations?

A: Both designations refer to the TO-220-2 case family with Through Hole mounting. The suffix variations (AC versus ACFP) indicate supplier-specific package designations but maintain mechanical and electrical compatibility within the TO-220-2 standard. Pin configuration and thermal characteristics remain consistent.

Q: Why is IDH05G120C5XKSA1 listed as a similar substitute if it has only 5 A rating?

A: IDH05G120C5XKSA1 is classified as a similar substitute because it meets the 1200 V voltage requirement and uses the same TO-220-2 package family. However, the 5 A current rating is 50% of the main part specification. This part is suitable only for applications with reduced current requirements and should not be used in designs requiring the full 10 A capability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant. SICR101200 is REACH affected, while all other substitutes are REACH unaffected. Verify REACH compliance requirements for your specific application and supply chain.

Q: What is the significance of reverse recovery time (trr) in these diodes?

A: Reverse recovery time indicates the speed at which the diode transitions from conducting to blocking state. The main part and most substitutes specify 0 ns recovery time, indicating zero reverse recovery behavior characteristic of Silicon Carbide Schottky technology. FFSP10120A specifies ≤ 500 ns recovery time, which is still considered fast recovery for this device class.

Q: Can FFSP10120A be used if forward voltage is slightly higher at 1.75 V?

A: FFSP10120A can be used in applications where the 0.15 V increase in forward voltage (1.75 V versus 1.6 V at 10 A) is acceptable. This results in slightly higher power dissipation. Verify thermal management and circuit design margins before substitution.

Q: Which substitute has the best reverse leakage characteristics?

A: IDH05G120C5XKSA1 has the lowest reverse leakage at 33 µA @ 1200 V, compared to 200 µA for the main part. However, this part is rated for only 5 A current. Among 10 A rated substitutes, SICR101200 has the lowest reverse leakage at 100 µA @ 1200 V.

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

A: SCS210KGC specifies maximum junction temperature of 175°C without minimum specification. SCS210KGC17 specifies 175°C maximum. FFSP10120A, IDH05G120C5XKSA1, SICR101200, and UJ3D1210TS all specify -55°C to 175°C operating range, providing broader thermal coverage for low-temperature applications.

Q: Are there inventory considerations for part selection?

A: Yes. UJ3D1210TS has the highest inventory (10136 units), followed by SCS210KGC17 (10100 units). FFSP10120A has 3556 units, IDH05G120C5XKSA1 has 4099 units, and SICR101200 has the lowest inventory at 750 units. For long-term supply chain planning, prioritize parts with higher inventory levels.
