Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on the following key parameters: IGBT type, voltage rating, current capability, package/case compatibility, environmental and compliance status, mounting type, and thermal endurance. Only products matching these criteria and with defined compatibility within the transistors, IGBTs category are considered valid substitutes. These criteria ensure electrical, mechanical, and regulatory alignment between the original and substitute part.

Key parameters:

• IGBT type
• Voltage - Collector Emitter Breakdown (Max)
• Vce(on) (Max) @ Vge, Ic
• Operating Temperature
• Mounting Type
• Package / Case
• RoHS and REACH status
• Moisture Sensitivity Level (MSL)

Parameter Comparison

Engineering Selection Recommendations

Engineering selection between IRGC4274B and SIGC76T65R3EX1SA1 should be based on product status, RoHS3 compliance, REACH status, and moisture sensitivity level as provided. IRGC4274B is obsolete, while SIGC76T65R3EX1SA1 is active and maintains equivalent compliance and packaging parameters.
