IR2133STR Equivalent & Substitute Parts

Part Overview

The IR2133STR is a half-bridge gate driver IC manufactured by Infineon Technologies, designed for driving IGBT and N-Channel MOSFET configurations in 3-phase power management applications. This component operates with a supply voltage range of 10V to 20V and provides peak output currents of 250mA (source) and 500mA (sink), with a maximum bootstrap voltage rating of 600V.

The IR2133STR is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure continued availability for new designs, maintenance applications, and production continuity where original stock becomes depleted or unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IR2133STR is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Half-Bridge topology
• Channel Type: 3-Phase operation
• Number of Drivers: 6 drivers
• Gate Type: IGBT and N-Channel MOSFET compatibility
• Voltage - Supply: 10V ~ 20V range
• Logic Voltage Levels: VIL 0.8V, VIH 2.2V
• Current - Peak Output: 250mA source, 500mA sink
• Input Type: Inverting configuration
• High Side Voltage - Max (Bootstrap): 600V
• Package / Case: 28-SOIC form factor

The IR2133STRPBF meets all these criteria and qualifies as a direct substitute. The primary distinction between these parts is product status and packaging configuration, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The IR2133STRPBF is the direct substitute for the IR2133STR. Both parts share identical electrical specifications and mechanical packaging. The IR2133STRPBF is preferred for new designs and ongoing production due to its active product status and ROHS3 compliance. The IR2133STR, classified as obsolete, should be replaced with the IR2133STRPBF in applications where component availability and regulatory compliance are considerations.

The moisture sensitivity level difference (MSL 1 versus MSL 3) reflects packaging and handling requirements. The IR2133STRPBF requires storage and handling within 168-hour moisture exposure limits, whereas the IR2133STR has unlimited moisture tolerance. This distinction affects supply chain logistics but does not impact electrical performance or circuit functionality.

Frequently Asked Questions (FAQ)

Q: Can the IR2133STRPBF directly replace the IR2133STR in existing designs?

A: Yes. The IR2133STRPBF is electrically and mechanically identical to the IR2133STR. All electrical parameters, including supply voltage, output current, logic levels, and timing specifications, are equivalent. The 28-SOIC package dimensions are identical, enabling direct PCB substitution without layout modifications.

Q: What is the difference between IR2133STR and IR2133STRPBF?

A: The primary differences are product status and compliance certifications. The IR2133STR is obsolete, while the IR2133STRPBF is active. The IR2133STRPBF is ROHS3 compliant, whereas the IR2133STR is non-compliant. Moisture sensitivity levels differ: MSL 1 (unlimited) for IR2133STR and MSL 3 (168 hours) for IR2133STRPBF. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: Both parts use the 28-SOIC package with identical dimensions (0.295", 7.50mm width). The IR2133STRPBF is available in Cut Tape (CT) and Digi-Reel packaging options, while the IR2133STR packaging configuration is not specified. This affects supply chain handling but not component performance or PCB integration.

Q: Why should I use IR2133STRPBF instead of IR2133STR?

A: The IR2133STRPBF is the recommended choice for new designs and production applications. It maintains active product status, ensuring long-term availability and supply chain reliability. ROHS3 compliance satisfies regulatory requirements in many markets. The IR2133STR, being obsolete, presents supply continuity risks and does not meet current environmental compliance standards.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both parts operate with 10V to 20V supply voltage, provide 250mA source and 500mA sink output currents, support 600V bootstrap voltage, and feature 90ns rise and 40ns fall times. Logic voltage thresholds (VIL 0.8V, VIH 2.2V) and operating temperature ratings (125°C TJ) are identical. All functional parameters for half-bridge gate driving applications are equivalent.
