IRS2453DSPBF Equivalent & Substitute Parts

Part Overview

The IRS2453DSPBF is a full-bridge gate driver IC manufactured by Infineon Technologies, designed for synchronous N-channel MOSFET applications with RC input circuit configuration. This component operates within a 10V to 15.6V supply voltage range and delivers peak output currents of 180mA (source) and 260mA (sink), supporting bootstrap voltages up to 600V. The device is currently classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs requiring this gate driver topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IRS2453DSPBF is determined by strict equivalence across the following critical parameters:

• Driven configuration (full-bridge topology)
• Channel type (synchronous operation)
• Gate type (N-channel MOSFET driver)
• Supply voltage range (10V ~ 15.6V)
• Logic voltage thresholds (VIL 4.7V, VIH 9.3V)
• Peak output current specifications (180mA source, 260mA sink)
• Input circuit type (RC input circuit)
• Bootstrap voltage capability (600V maximum)
• Timing characteristics (120ns rise, 50ns fall)
• Operating temperature range (-25°C ~ 125°C)
• Package form factor (14-SOIC)
• Regulatory compliance (ROHS3, REACH Unaffected)

The IRS2453DSTRPBF qualifies as a direct substitute based on identical electrical and mechanical specifications. The distinction between these parts lies exclusively in packaging format: the main part (DSPBF) is supplied in tube packaging, while the substitute (DSTRPBF) is supplied in tape and reel format. Both share the same base product number (IRS2453) and maintain full parameter equivalence.

Parameter Comparison

Engineering Selection Recommendations

The IRS2453DSTRPBF is the designated manufacturer-recommended substitute for the obsolete IRS2453DSPBF. Selection between these parts is determined by procurement and assembly requirements rather than electrical or functional differences.

The IRS2453DSTRPBF is the appropriate choice for high-volume production environments utilizing automated pick-and-place assembly equipment, as tape and reel packaging integrates directly with standard surface-mount assembly processes. This part maintains active product status with Infineon Technologies, ensuring ongoing availability and supply chain stability.

The IRS2453DSPBF, supplied in tube packaging, is suitable for manual assembly, prototyping, or low-volume applications where automated handling is not required. However, given its obsolete classification, sourcing may be limited to existing inventory channels.

Both parts satisfy identical electrical specifications, regulatory compliance requirements (ROHS3, REACH Unaffected), and environmental operating conditions. PCB layout, schematic integration, and thermal management considerations remain unchanged between these alternatives.

Frequently Asked Questions (FAQ)

Q: Are the IRS2453DSPBF and IRS2453DSTRPBF electrically identical?

A: Yes. Both parts share identical electrical specifications, including supply voltage range (10V ~ 15.6V), output current ratings (180mA source, 260mA sink), logic voltage thresholds (4.7V, 9.3V), bootstrap voltage capability (600V), and timing characteristics (120ns rise, 50ns fall). The only difference is packaging format.

Q: What is the difference between tube and tape & reel packaging?

A: Tube packaging (DSPBF) contains individual components in a plastic tube suitable for manual handling and low-volume assembly. Tape and reel packaging (DSTRPBF) presents components on a continuous carrier tape wound on a reel, designed for automated surface-mount assembly equipment. Both formats contain the same die and deliver identical performance.

Q: Can I use IRS2453DSTRPBF in place of IRS2453DSPBF in existing designs?

A: Yes. The IRS2453DSTRPBF is a direct substitute with no design modifications required. PCB footprint, pin configuration, and electrical behavior are identical. The 14-SOIC package dimensions (0.154" width, 3.90mm) remain constant.

Q: Why is the IRS2453DSPBF classified as obsolete?

A: Obsolescence reflects Infineon's product lifecycle management. The active equivalent IRS2453DSTRPBF provides continued access to this gate driver topology with identical specifications and ongoing manufacturer support.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts maintain ROHS3 compliance, REACH Unaffected status, and identical moisture sensitivity levels (MSL 2, 1 Year). Environmental and regulatory requirements are fully equivalent.

Q: Which part should I specify for new designs?

A: Specify IRS2453DSTRPBF for new designs. This part carries active product status, ensuring long-term availability and manufacturer support. If manual assembly or prototyping is required, tube packaging can be obtained through component distributors.
