IRGC50B60KB Equivalent & Substitute Parts Reference

Part Overview

The IRGC50B60KB is an NPT (Non-Punch Through) IGBT chip from Infineon Technologies in the category of Transistors, IGBTs. It features a maximum collector-emitter voltage of 600 V and a maximum collector current of 50 A in a surface mount die package. As this product is currently designated as obsolete, identifying appropriate substitute models is essential to ensure long-term supply continuity. Substitute selection focuses on maintaining compatibility in critical electrical and packaging parameters within this IGBT product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution is determined strictly by matching key parameters within the same product category (Transistors, IGBTs). The substitute part must have the same package type (Surface Mount Die), identical maximum collector-emitter voltage (600 V), and maximum collector current (50 A). The Vce(on) parameter is considered for comparative performance. Compliance with RoHS and REACH, and matching Moisture Sensitivity Level, are maintained to support regulatory and supply chain requirements. Only these explicit characteristics provided in the input are considered for substitution.

Key parameters for substitution:

• Voltage - Collector Emitter Breakdown (Max)
• Current - Collector (Ic) (Max)
• Mounting Type / Package / Case
• Input Type
• RoHS Status
• Moisture Sensitivity Level (MSL)
• REACH Status

Parameter Comparison

Engineering Selection Recommendations

Selection should be based on the product status and compliance certifications. The IRGC50B60KB is obsolete, while SIGC28T60EX1SA4 is active. Both parts are ROHS3 compliant and REACH unaffected, with identical moisture sensitivity levels. These characteristics support direct substitution where product availability and regulatory compliance are critical.

Frequently Asked Questions (FAQ)

Q: What key specifications should match when selecting an IGBT substitute for IRGC50B60KB?
A: Substitute parts must have the same collector-emitter breakdown voltage, collector current rating, package type, RoHS status, MSL, and REACH status.

Q: Is the package type identical between IRGC50B60KB and SIGC28T60EX1SA4?
A: Both IGBT chips are supplied in surface mount die packages.

Q: Are there differences in IGBT type between the original and substitute part?
A: The IRGC50B60KB uses NPT technology; the SIGC28T60EX1SA4 uses Trench Field Stop technology. All parameters governing substitution listed are matched per provided data.

Q: What is the regulatory compliance status of the substitute part?
A: SIGC28T60EX1SA4 is ROHS3 compliant, REACH unaffected, and has MSL 1 (Unlimited), matching the main part.

Q: Why is substitution necessary for the IRGC50B60KB?
A: The IRGC50B60KB is obsolete; substitution is required for continued supply.

Q: Does substituting the part affect mounting or package considerations?
A: Both parts utilize the same surface mount die format specified in the product parameters.
