| FFF Compatibility | Identical 14-SOIC pinout configuration with exact match of all signal, return, and no-connect pins.Identical 14-SOIC physical package dimensions, thermal characteristics, and surface-mount footprint.Equivalent electrical and timing specifications, absolute maximum ratings, and 600V offset voltage capability. | Matches the 14-SOIC footprint, but Pin 2 is active-high (LIN) instead of active-low (LIN\), and Pin 4 is a No Connect (NC) instead of the deadtime programming pin (DT).Shares the standard 14-SOIC package footprint and surface-mount dimensions.Requires logic inversion on the low-side control input because the LIN pin is active-high. Deadtime is fixed internally instead of programmable via the external resistor on Pin 4. | ||
 AI Summary | IRS21834SPBF by Infineon Technologies: Half-Bridge Gate Driver IC Inverting, Non-Inverting 14-SOIC. | This is the active Tape & Reel packaged variant of the obsolete tube-packaged IRS21834SPBF. It features the exact same silicon and package, serving as a perfect drop-in replacement with no circuit or layout changes needed.
| This is a high-performance 600V gate driver from Microchip that fits the same footprint. It requires logic inversion of the low-side control input in firmware or hardware, and utilizes a fixed internal deadtime rather than the baseline's resistor-programmable deadtime.

All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
Frequently asked questions
Yes. The Infineon Technologies IRS21834SPBF is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
The closest qualified second sources for the Infineon Technologies IRS21834SPBF are the IRS21834STRPBF (Infineon Technologies) and the MCP14LH21814-E/SL (Microchip Technology), out of 3 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the IRS21834SPBF are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
The IRS21834SPBF (Infineon Technologies) is a part in the Power Management (PMIC) category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
