Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRS44262SPBF is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Low-Side
• Number of Drivers: 2 (independent channels)
• Gate Type: IGBT, N-Channel MOSFET compatibility
• Voltage - Supply: 11.2V ~ 20V
• Logic Voltage - VIL, VIH: 0.8V, 2.5V
• Current - Peak Output (Source, Sink): 2.3A, 3.3A
• Input Type: Inverting
• Rise / Fall Time (Typ): 25ns, 25ns
• Operating Temperature: -40°C ~ 150°C (TJ)
• Package / Case: 8-SOIC (0.154", 3.90mm Width)

The IRS44262STRPBF qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is packaging format: the substitute is supplied in Tape & Reel (TR) configuration versus the original bulk packaging, and product status transitions from obsolete to active.

Parameter Comparison

Engineering Selection Recommendations

The IRS44262STRPBF is a direct functional equivalent to the IRS44262SPBF. Both components share identical electrical characteristics, thermal operating range, and mechanical package specifications. The substitute maintains full ROHS3 compliance and REACH unaffected status.

The transition from obsolete to active product status for the IRS44262STRPBF provides supply chain continuity. The Tape & Reel packaging format of the substitute is standard for production environments and offers improved handling and automated assembly compatibility compared to bulk packaging.

Selection of the IRS44262STRPBF eliminates obsolescence risk while preserving all functional and compliance requirements of the original design.

Frequently Asked Questions (FAQ)

Q: Are the IRS44262SPBF and IRS44262STRPBF electrically identical?

A: Yes. Both components have identical electrical specifications including supply voltage range (11.2V ~ 20V), output current ratings (2.3A source, 3.3A sink), logic voltage thresholds (0.8V, 2.5V), and switching characteristics (25ns rise/fall time).

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. The IRS44262SPBF uses bulk packaging, while the IRS44262STRPBF is supplied in Tape & Reel (TR) format. Additionally, the IRS44262STRPBF maintains active product status, whereas the original is obsolete.

Q: Can I use IRS44262STRPBF as a direct replacement in existing designs?

A: Yes. The IRS44262STRPBF is a direct substitute. It maintains the same 8-SOIC package footprint, pin configuration, and all electrical specifications. No circuit modifications are required.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical Moisture Sensitivity Level (MSL) ratings of 2 (1 Year).

Q: Why is the original part marked as obsolete?

A: The IRS44262SPBF is classified as obsolete product status. The IRS44262STRPBF represents the active continuation of this gate driver family with identical functionality.
