Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IRS25091SPBF is determined by the following critical parameters:

• Driven Configuration: Must be Half-Bridge
• Number of Drivers: Must be 2
• Gate Type: Must support IGBT and N-Channel MOSFET
• Voltage - Supply: Must operate within 10V ~ 20V range
• Input Type: Must be Non-Inverting
• High Side Voltage - Max (Bootstrap): Must support 600V
• Package / Case: Must be 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Must be Surface Mount

The identified substitute parts meet all mandatory electrical and mechanical parameters. Variations in peak output current, rise/fall time, operating temperature range, and product status are noted but do not preclude functional substitution within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

IRS21091SPBF (Infineon Technologies): This substitute maintains identical driven configuration, driver count, gate type support, supply voltage range, input type, and bootstrap voltage specifications. The device is classified as obsolete, matching the status of the primary part. Peak output current capabilities exceed the original specification, and rise/fall times are improved. This part is suitable for direct substitution in existing designs with no circuit modifications required.

NCP5304DR2G (onsemi): This substitute meets all mandatory electrical and mechanical parameters for half-bridge gate driver functionality. The device is classified as active, providing superior long-term availability compared to the obsolete IRS25091SPBF. Peak output current and switching speed performance exceed the original specification. The operating temperature range is reduced to -40°C ~ 125°C (TJ), which may require evaluation for applications requiring operation above 125°C. RoHS3 compliance and improved moisture sensitivity level (MSL 1) provide enhanced environmental and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can IRS21091SPBF be used as a direct replacement for IRS25091SPBF?

A: Yes. Both devices share identical half-bridge configuration, dual-driver topology, IGBT/N-Channel MOSFET gate type support, 10V-20V supply voltage range, non-inverting input logic, and 600V bootstrap voltage rating. The 8-SOIC package and surface mount characteristics are identical. No circuit modifications are required.

Q: What are the key differences between IRS21091SPBF and NCP5304DR2G?

A: Both parts meet the core substitution criteria. IRS21091SPBF is an Infineon device with obsolete status. NCP5304DR2G is an onsemi device with active product status, offering improved long-term availability. NCP5304DR2G features faster switching times (85ns/35ns vs. 100ns/35ns), higher peak output current (250mA/500mA vs. 290mA/600mA), and superior moisture sensitivity (MSL 1 vs. MSL 2). The NCP5304DR2G operating temperature maximum is 125°C versus 150°C for the Infineon parts.

Q: Are there package compatibility concerns when substituting these parts?

A: No. All three parts use identical 8-SOIC packaging (0.154", 3.90mm width) with surface mount mounting type. PCB footprints and assembly processes remain unchanged.

Q: Which substitute part should be selected for new designs?

A: NCP5304DR2G is recommended for new designs due to active product status, ensuring sustained availability and supply chain stability. Verify that the -40°C ~ 125°C operating temperature range meets application requirements.

Q: Do the substitute parts have different compliance certifications?

A: NCP5304DR2G and IRS21091SPBF both carry ROHS3 compliance certification. Moisture sensitivity levels differ: NCP5304DR2G is MSL 1 (unlimited shelf life), while IRS21091SPBF is MSL 2 (1 year shelf life). Both parts maintain REACH Unaffected and EAR99 ECCN status.
