IR2101STR Half-Bridge Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IR2101STR is a half-bridge gate driver IC manufactured by Infineon Technologies, designed to drive IGBT and N-Channel MOSFET devices in power management applications. This component features independent dual-channel configuration with non-inverting input logic and operates across a 10V to 20V supply voltage range.

The IR2101STR is classified as obsolete, which necessitates identification of functionally equivalent alternatives for new designs and ongoing production requirements. The primary substitute maintains identical electrical and mechanical specifications while offering improved product status and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IR2101STR is determined by strict equivalence across all electrical and mechanical parameters. The substitute part IR2101STRPBF maintains identical specifications in the following critical areas:

Driven configuration (half-bridge), channel architecture (independent dual-channel), gate type compatibility (IGBT and N-Channel MOSFET), input logic (non-inverting), supply voltage range (10V ~ 20V), logic voltage thresholds (0.8V, 3V), peak output current ratings (210mA source, 360mA sink), bootstrap voltage capability (600V maximum), switching characteristics (100ns rise, 50ns fall time), operating temperature range (-40°C ~ 150°C), and physical package specification (8-SOIC surface mount).

The IR2101STRPBF is classified as a direct manufacturer equivalent with active product status, making it the primary substitute for obsolete IR2101STR applications.

Parameter Comparison

Engineering Selection Recommendations

The IR2101STRPBF is the direct functional equivalent of the IR2101STR and is suitable for all applications requiring half-bridge gate driver functionality with the specified electrical and mechanical parameters.

Selection of IR2101STRPBF over IR2101STR is justified by the following factors:

Product status: IR2101STRPBF maintains active manufacturing status, ensuring long-term availability and supply chain continuity, whereas IR2101STR is obsolete.

Regulatory compliance: IR2101STRPBF is ROHS3 compliant, meeting current environmental and regulatory requirements for electronic components in most jurisdictions. IR2101STR is non-compliant with RoHS standards.

Moisture sensitivity: IR2101STRPBF carries MSL 2 (1 Year), representing standard moisture handling requirements consistent with modern manufacturing and storage practices.

All electrical and mechanical specifications remain identical between the two parts, ensuring direct pin-for-pin and functional compatibility in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can IR2101STRPBF be used as a direct replacement for IR2101STR in existing designs?

A: Yes. IR2101STRPBF is electrically and mechanically identical to IR2101STR across all specified parameters, including gate driver configuration, output current ratings, voltage specifications, switching characteristics, and 8-SOIC package dimensions. No circuit modifications are required.

Q: What is the primary reason to transition from IR2101STR to IR2101STRPBF?

A: IR2101STR is classified as obsolete, creating supply and long-term availability risks. IR2101STRPBF is an active product with equivalent specifications and improved compliance status (ROHS3 compliant versus non-compliant).

Q: Are there any differences in electrical performance between IR2101STR and IR2101STRPBF?

A: No. Both parts maintain identical electrical specifications: 10V ~ 20V supply voltage, 0.8V/3V logic thresholds, 210mA/360mA peak output current (source/sink), 600V bootstrap voltage, and 100ns/50ns rise/fall times.

Q: What is the difference in Moisture Sensitivity Level (MSL) between these parts?

A: IR2101STR carries MSL 1 (Unlimited), while IR2101STRPBF carries MSL 2 (1 Year). MSL 2 represents standard moisture handling with a one-year shelf life under controlled conditions. This difference does not affect electrical performance or functionality.

Q: Are both parts available in the same packaging format?

A: Yes. Both IR2101STR and IR2101STRPBF are supplied in 8-SOIC surface mount packages with identical physical dimensions (0.154" width, 3.90mm). PCB layouts and assembly processes require no modification.

Q: What is the compliance difference between IR2101STR and IR2101STRPBF?

A: IR2101STRPBF is ROHS3 compliant, meeting current environmental regulations for restricted hazardous substances. IR2101STR is non-compliant. Both parts are REACH Unaffected and carry EAR99 export classification.
