IR2301STR Equivalent & Substitute Parts

Part Overview

The IR2301STR is a high-side or low-side gate driver IC manufactured by Infineon Technologies, designed for driving IGBT and N-Channel MOSFET gates in power management applications. The device operates with a supply voltage range of 5V to 20V and features independent dual-channel configuration with non-inverting input logic. Currently, the IR2301STR holds obsolete product status, making identification of active equivalent parts essential for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IR2301STR is determined by strict equivalence across the following electrical and mechanical parameters:

• Identical base product number (IR2301)
• Matching package type (8-SOIC with 0.154" / 3.90mm width)
• Identical driven configuration (High-Side or Low-Side)
• Matching number of independent drivers (2 channels)
• Compatible gate types (IGBT, N-Channel MOSFET)
• Identical supply voltage range (5V ~ 20V)
• Matching peak output current specifications (200mA source, 350mA sink)
• Identical bootstrap voltage rating (600V maximum)
• Matching operating temperature range (-40°C ~ 150°C)

The IR2301STRPBF represents a direct functional equivalent with identical electrical characteristics and mechanical compatibility. The primary distinction lies in packaging format and product lifecycle status.

Engineering Selection Recommendations

The IR2301STRPBF is the active equivalent for the obsolete IR2301STR. Selection between these parts is determined by application requirements and regulatory compliance:

IR2301STR — Suitable for legacy systems, repair applications, or designs where RoHS non-compliance is acceptable. Product status is obsolete; availability is limited to existing inventory.

IR2301STRPBF — Recommended for new designs and production applications. This part maintains identical electrical and mechanical specifications while offering active product status, ROHS3 compliance, and significantly higher inventory availability. The Tape & Reel packaging format supports automated assembly processes. Moisture Sensitivity Level 2 requires standard handling procedures during storage and assembly.

Both parts are functionally interchangeable at the circuit level. Selection should be based on design phase (legacy vs. new), regulatory requirements, and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can IR2301STRPBF replace IR2301STR in existing designs?

A: Yes. Both parts share identical electrical characteristics, gate driver functionality, supply voltage range, output current ratings, and 8-SOIC package dimensions. Direct substitution is electrically and mechanically compatible.

Q: What is the difference between IR2301STR and IR2301STRPBF?

A: The primary differences are product status (obsolete vs. active), packaging format (bulk vs. Tape & Reel), RoHS compliance (non-compliant vs. ROHS3 compliant), and Moisture Sensitivity Level (MSL 1 vs. MSL 2). Electrical performance and pin configuration are identical.

Q: Why is IR2301STR marked as obsolete?

A: The IR2301STR has reached end-of-life status. Infineon Technologies continues to support the IR2301 product line through the active IR2301STRPBF variant, which incorporates modern compliance standards.

Q: Does the Tape & Reel packaging affect circuit performance?

A: No. Tape & Reel is a supply format for automated assembly. The IC itself is identical to bulk-packaged versions. Tape & Reel packaging improves production efficiency and reduces handling costs.

Q: What does ROHS3 compliance mean for this part?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. This is required for many industrial and consumer applications, particularly in European markets.

Q: How should IR2301STRPBF be stored given MSL 2 rating?

A: MSL 2 requires storage in controlled humidity conditions (typically ≤30% relative humidity at 25°C) for up to one year. Standard moisture-barrier packaging and desiccant storage are recommended for extended shelf life.

Q: Are there any pin or footprint differences between these parts?

A: No. Both parts use identical 8-SOIC package dimensions (0.154" / 3.90mm width) with matching pin assignments and footprints.
