IR2153PBF Equivalent & Substitute Parts

Part Overview

The IR2153PBF is a half-bridge gate driver IC manufactured by Infineon Technologies, designed for synchronous N-channel MOSFET applications with RC input circuit configuration. This device operates within a 10V to 15.6V supply voltage range and supports bootstrap voltages up to 600V, making it suitable for power management applications requiring dual-channel gate driving capability.

The IR2153PBF carries a "Not For New Designs" product status, indicating that Infineon has discontinued active development and support for this component. This status necessitates identification of functionally equivalent alternatives to ensure design continuity, supply chain reliability, and long-term component availability for existing applications and legacy system maintenance.

Substitute Part Grouping Explanation

Substitution eligibility for the IR2153PBF is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Driven configuration must be half-bridge
• Channel type must be synchronous
• Number of drivers must be 2
• Gate type must be N-channel MOSFET
• Supply voltage range must be 10V ~ 15.6V
• Input type must be RC input circuit
• Bootstrap voltage rating must be minimum 600V
• Rise and fall time specifications must match: 80ns and 45ns respectively
• Operating temperature range must encompass -40°C ~ 125°C (TJ)

Mechanical & Packaging Requirements:

• Package must be 8-DIP (0.300", 7.62mm)
• Mounting type must be through hole

Compliance Requirements:

• RoHS3 compliance status must be maintained
• Moisture sensitivity level must be 1 (Unlimited)

The IR21531PBF meets all specified criteria and qualifies as a direct substitute for the IR2153PBF.

Parameter Comparison

Engineering Selection Recommendations

The IR21531PBF is a direct functional equivalent to the IR2153PBF. Both components are manufactured by Infineon Technologies and maintain identical electrical, mechanical, and compliance specifications across all critical parameters.

Selection between these parts should be based on:

Product Status Consideration: Both components carry "Not For New Designs" status from Infineon Technologies. For new design implementations, evaluation of current-generation gate driver alternatives from Infineon or other manufacturers is recommended to ensure long-term supply chain viability and access to manufacturer technical support.

Compliance & Certification: Both parts maintain ROHS3 compliance, REACH unaffected status, and identical export classification (EAR99). No compliance barriers exist for substitution in either direction.

Inventory & Availability: The IR2153PBF has 50,400 units in stock, while the IR21531PBF has 3,858 units in stock. Component selection may be influenced by immediate availability requirements and supply chain lead times.

Pin-to-Pin Compatibility: Both components utilize identical 8-DIP through-hole packaging with matching pinout configurations, enabling direct PCB-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the IR21531PBF be used as a direct replacement for the IR2153PBF in existing designs?

A: Yes. The IR21531PBF is electrically and mechanically equivalent to the IR2153PBF. All critical parameters including supply voltage, bootstrap voltage rating, gate driver configuration, timing specifications, and package format are identical. Direct substitution is possible without circuit modifications.

Q: Are there any differences in the pin configuration between these two parts?

A: No. Both the IR2153PBF and IR21531PBF use identical 8-DIP (0.300", 7.62mm) through-hole packaging with matching pinout. PCB footprints and component placement are interchangeable.

Q: What does "Not For New Designs" status mean for these components?

A: This status indicates that Infineon Technologies has discontinued active development and support for these gate driver ICs. While existing inventory remains available and the parts continue to function as specified, Infineon does not recommend these components for new product development. For new designs, current-generation alternatives should be evaluated.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the IR2153PBF and IR21531PBF are ROHS3 compliant with moisture sensitivity level 1 (unlimited). They meet all applicable environmental and regulatory requirements for industrial and commercial applications.

Q: Which part should I select based on availability?

A: The IR2153PBF has significantly higher inventory (50,400 units) compared to the IR21531PBF (3,858 units). If immediate availability is critical, the IR2153PBF is the preferred choice. Both parts are functionally equivalent, so selection can be based on supply chain requirements.

Q: Can these parts be used in high-temperature applications?

A: Both components are rated for operating temperatures from -40°C to 125°C (junction temperature). Applications requiring operation beyond this range require alternative components with higher temperature ratings.
