Substitute Part Grouping Explanation

Substitution of the BSM35GD120DN2 is determined by strict alignment of the following critical electrical and mechanical parameters:

Mandatory Matching Parameters:

IGBT Type: NPT
Configuration: Three Phase Inverter
Voltage - Collector Emitter Breakdown (Max): 1200 V
Current - Collector (Ic) (Max): 50 A
Mounting Type: Chassis Mount
Input: Standard

Allowable Parameter Variations: Substitute parts may differ in maximum power rating, Vce(on) characteristics, input capacitance, operating temperature range, and package designation, provided the mandatory parameters remain constant. These variations do not affect functional compatibility in applications designed for the BSM35GD120DN2.

The MWI25-12A7 from IXYS meets all mandatory matching criteria and is classified as a direct substitute for the obsolete BSM35GD120DN2.

Engineering Selection Recommendations

The MWI25-12A7 is an active product from IXYS and serves as the direct substitute for the obsolete BSM35GD120DN2. Both components share identical electrical specifications for voltage rating, current rating, IGBT type, and three-phase inverter configuration.

Product Status Consideration: The BSM35GD120DN2 is obsolete, while the MWI25-12A7 is active and currently in production. Selection of the MWI25-12A7 ensures long-term supply availability and ongoing manufacturer support.

Compliance Status: Both parts maintain REACH Unaffected status and carry MSL 1 (Unlimited) moisture sensitivity classification, indicating equivalent environmental compliance and handling requirements.

Package Designation: The BSM35GD120DN2 uses a generic Module package designation, while the MWI25-12A7 specifies the E2 package format. Both are chassis mount configurations suitable for identical mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the MWI25-12A7 directly replace the BSM35GD120DN2 in existing applications?

A: Yes. Both components share identical voltage rating (1200 V), current rating (50 A), IGBT type (NPT), and three-phase inverter configuration. The MWI25-12A7 is electrically and mechanically compatible for chassis mount applications designed for the BSM35GD120DN2.

Q: What are the differences between these two parts?

A: The MWI25-12A7 has a lower maximum power rating (225 W versus 280 W), lower Vce(on) characteristics (2.7 V versus 3.2 V), lower input capacitance (1.65 nF versus 2 nF), and a different operating temperature range (-40°C to 125°C versus 150°C). The MWI25-12A7 uses the E2 package designation. These differences do not affect functional compatibility for applications within the specified operating parameters.

Q: Why is the BSM35GD120DN2 listed as obsolete?

A: The BSM35GD120DN2 has been discontinued by Infineon Technologies. The MWI25-12A7 from IXYS is the recommended active substitute that maintains electrical and mechanical compatibility.

Q: Are there any compliance or certification differences?

A: Both parts maintain identical REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity classification. No compliance or certification differences exist between these components.

Q: What is the significance of the E2 package designation for the MWI25-12A7?

A: The E2 package is the IXYS standard module package format for three-phase inverter IGBT modules. It is compatible with chassis mount applications and maintains the same form factor and mounting interface as the BSM35GD120DN2 Module package.

Q: Can I use the MWI25-12A7 in high-temperature applications requiring 150°C operation?

A: The MWI25-12A7 has a maximum operating temperature of 125°C. Applications requiring sustained operation at 150°C would exceed the MWI25-12A7 specification. Alternative components with higher temperature ratings must be evaluated for such applications.
