Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRG4BC30S-SPBF is determined by the following critical electrical and mechanical parameters:

Voltage Rating: The substitute part must maintain a collector-emitter breakdown voltage of 600V to ensure safe operation within the same voltage domain.

Package Configuration: The substitute part must use the D2PAK (TO-263-3) surface mount package to ensure mechanical and thermal compatibility with existing PCB layouts and thermal management designs.

Operating Temperature Range: The substitute part must support the full operating temperature range of -55°C to 150°C (junction temperature) to maintain functional equivalence across all environmental conditions.

Current and Power Ratings: While the substitute part may have different maximum collector current and power dissipation specifications, these parameters must be evaluated against the specific application requirements to ensure adequate performance margin.

The STGB10NC60KDT4 from STMicroelectronics meets the voltage rating, package configuration, and operating temperature requirements. However, this substitute exhibits reduced maximum collector current (20A versus 34A) and lower power dissipation (65W versus 100W), which may limit its applicability to lower-current circuit implementations.

Parameter Comparison

Engineering Selection Recommendations

The STGB10NC60KDT4 is classified as an active product with current manufacturing support and availability, whereas the IRG4BC30S-SPBF is obsolete. This status difference makes the STGB10NC60KDT4 suitable for new designs and ongoing production support.

Both parts share identical voltage ratings (600V), operating temperature ranges (-55°C to 150°C), and D2PAK packaging, establishing mechanical and thermal compatibility.

The STGB10NC60KDT4 carries RoHS3 compliance certification, whereas the IRG4BC30S-SPBF compliance status is not specified in the provided data. Both parts are REACH Unaffected and classified under ECCN EAR99.

Selection of the STGB10NC60KDT4 as a substitute requires verification that the application circuit operates within the reduced current (20A maximum) and power (65W maximum) specifications. Applications requiring the full 34A collector current or 100W power dissipation of the original part cannot use this substitute without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the STGB10NC60KDT4 be used as a direct replacement for the IRG4BC30S-SPBF in all applications?

A: No. While both parts share the same voltage rating, operating temperature range, and D2PAK package, the STGB10NC60KDT4 has reduced maximum collector current (20A versus 34A) and power dissipation (65W versus 100W). Direct substitution is only valid for applications operating within these lower specifications.

Q: What are the key compatibility factors between these two IGBTs?

A: The primary compatibility factors are: (1) identical 600V collector-emitter breakdown voltage, (2) identical -55°C to 150°C operating temperature range, (3) identical D2PAK surface mount package configuration, and (4) identical MSL rating of 1 (Unlimited).

Q: Why does the STGB10NC60KDT4 have different Vce(on) specifications?

A: The Vce(on) values are measured at different test conditions. The IRG4BC30S-SPBF is tested at 18A collector current, while the STGB10NC60KDT4 is tested at 5A. These measurements reflect the on-state voltage characteristics at their respective rated operating points and are not directly comparable without circuit-level analysis.

Q: Is the STGB10NC60KDT4 suitable for designs requiring the full 34A current rating of the original part?

A: No. The STGB10NC60KDT4 is rated for a maximum collector current of 20A. Applications requiring 34A operation must either use the original IRG4BC30S-SPBF (if available through inventory channels) or redesign the circuit to operate within the 20A limit.

Q: What is the significance of the product status difference between these parts?

A: The IRG4BC30S-SPBF is obsolete, indicating discontinued manufacturing and limited future availability. The STGB10NC60KDT4 is active, ensuring ongoing production, supply chain availability, and manufacturer support for new designs and production runs.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts are REACH Unaffected and classified under ECCN EAR99. The STGB10NC60KDT4 carries RoHS3 compliance certification. Compliance status for the IRG4BC30S-SPBF is not specified in the provided data.
