Engineering Selection Recommendations

Primary Recommendation: IRS4428STRPBF

The IRS4428STRPBF is the direct successor to the IR4428STRPBF from the same manufacturer, Infineon Technologies. It maintains identical electrical specifications (6V ~ 20V supply, dual low-side configuration, inverting/non-inverting inputs) and package form factor. The IRS4428STRPBF carries Active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment.

Alternative Recommendations: IXYS IXDF602 Series

The IXDF602SIA and IXDF602SIATR devices from IXYS Integrated Circuits Division provide extended supply voltage range (4.5V ~ 35V) while maintaining the required dual low-side driver configuration and 8-SOIC package. Both variants are Active products with ROHS3 compliance. The IXDF602SIATR is supplied in Cut Tape & Digi-Reel packaging, suitable for automated assembly environments.

Secondary Alternatives: Analog Devices Maxim Integrated Series

The MAX4428 and MAX628 families from Analog Devices Inc./Maxim Integrated offer dual low-side gate driver functionality in 8-SOIC packages with Active product status and ROHS3 compliance. These devices operate within the 4.5V ~ 18V supply range and support both N-Channel and P-Channel MOSFET gate driving. Multiple temperature and packaging variants are available to match specific application requirements.

Voltage Range Consideration: LM5111-3MX/NOPB

The LM5111-3MX/NOPB from National Semiconductor operates at 3.5V ~ 14V supply voltage, which overlaps the lower portion of the IR4428STRPBF specification. This device is suitable for applications where the supply voltage does not exceed 14V. It is an Active product with dual low-side driver configuration and 8-SOIC package compatibility.

Frequently Asked Questions (FAQ)

Q: Can the IRS4428STRPBF directly replace the IR4428STRPBF without circuit modifications?

A: Yes. The IRS4428STRPBF is the active-status successor from Infineon Technologies with identical electrical specifications, pin configuration, and 8-SOIC package dimensions. No circuit modifications are required for direct substitution.

Q: What is the primary difference between the IR4428STRPBF and IXDF602 series devices?

A: The IXDF602 series supports an extended supply voltage range of 4.5V ~ 35V compared to the IR4428STRPBF specification of 6V ~ 20V. Both maintain dual low-side driver configuration, inverting/non-inverting inputs, and 8-SOIC packaging. The IXDF602 series also supports P-Channel MOSFET gate driving in addition to IGBT and N-Channel MOSFET applications.

Q: Are all substitute parts available in the same packaging options?

A: Packaging availability varies by part number. The IRS4428STRPBF is available in Cut Tape & Digi-Reel packaging. The IXDF602 series offers both Tube and Cut Tape & Digi-Reel options. Maxim Integrated MAX4428 and MAX628 variants are supplied in Tube, Cut Tape & Digi-Reel, and Tape & Reel configurations. Verify specific packaging availability with your supplier for production requirements.

Q: Which substitute part has the fastest switching performance?

A: The IXDF602SIA and IXDF602SIATR devices feature the fastest rise and fall times at 7.5ns and 6.5ns respectively. The IR4428STRPBF and IRS4428STRPBF specify 25ns rise and fall times. Maxim Integrated MAX4428 and MAX628 devices specify 20ns rise and fall times. Application-specific switching speed requirements should guide part selection.

Q: What is the moisture sensitivity level difference between substitute parts?

A: The IR4428STRPBF specifies MSL 2 (1 Year). The IRS4428STRPBF and IXDF602 series specify MSL 1 (Unlimited), indicating superior moisture resistance and extended shelf life. Maxim Integrated MAX4428 and MAX628 devices also specify MSL 1 (Unlimited). Lower MSL ratings provide advantages in storage, handling, and long-term reliability.

Q: Can the LM5111-3MX/NOPB be used in applications requiring the full 6V ~ 20V supply range?

A: No. The LM5111-3MX/NOPB operates at 3.5V ~ 14V supply voltage. It is suitable only for applications where the supply voltage remains below 14V. For applications requiring operation at supply voltages above 14V, select IRS4428STRPBF, IXDF602 series, or Maxim Integrated alternatives.

Q: Are all substitute parts ROHS3 compliant?

A: The IRS4428STRPBF, IXDF602 series, and all Maxim Integrated variants (MAX4428 and MAX628 families) are ROHS3 compliant. The LM5111-3MX/NOPB does not specify RoHS status in the provided data. Verify RoHS compliance requirements with your regulatory and procurement teams before final part selection.
