Key Parameters

Substitute Part Grouping Explanation

Substitute identification for IGBT parts is based strictly on the following key allowed parameters:

• Maximum collector-emitter voltage rating
• Maximum continuous collector current
• Maximum power dissipation
• Package compatibility with D2PAK/TO-263
• RoHS compliance status
• Moisture Sensitivity Level (MSL)
• Product status (active or obsolete)

All substitutes listed satisfy the defined electrical ratings, power dissipation, mechanical packaging, and compliance criteria.

Parameter Comparison

Engineering Selection Recommendations

Based on the provided product status and compliance data, the LGS8206AUI from Littelfuse Inc. is obsolete, while the ISL9V3040S3ST from onsemi is active. Both IGBTs share RoHS compliance and a Moisture Sensitivity Level of 1 (Unlimited). The ISL9V3040S3ST provides equivalent or closely matching electrical and packaging parameters and fulfills all necessary compliance standards for direct substitution where an active and supported component is required.

Frequently Asked Questions (FAQ)

Q1: What are the primary selection criteria for substituting IGBTs in this product category?
A1: The primary criteria are: collector-emitter voltage rating, collector current, maximum power dissipation, package compatibility, RoHS status, and Moisture Sensitivity Level (MSL).

Q2: Are the packages of LGS8206AUI and ISL9V3040S3ST compatible?
A2: LGS8206AUI uses a D2PAK3 package; ISL9V3040S3ST uses a TO-263-3, D2PAK (2 Leads + Tab), TO-263AB package, which aligns with D2PAK form factors.

Q3: Why must a substitute part be active?
A3: Active part status ensures current manufacturing support for production and replacement needs.

Q4: What compliance standards do the listed substitutes meet?
A4: Both listed parts meet RoHS compliance and are designated Moisture Sensitivity Level 1 (Unlimited).

Q5: Is there an exact one-to-one mapping for every parameter between the LGS8206AUI and ISL9V3040S3ST?
A5: The substitutes match on all provided key parameters permitted for substitution within this product category.
