2026-09-10 LM224DR2G Stock, Datasheet & Alternatives: LM324 and LM2902 Replacement Guide
LM224DR2G is a commonly used quad operational amplifier for industrial control, signal conditioning, power management, test equipment, consumer electronics and general analog circuit designs. For OEM buyers, the key question is not only whether the base function is similar, but whether the exact part number, package, electrical parameters, lifecycle status, stock condition and approved substitute list match the BOM.
This guide explains what buyers should check before sourcing LM224DR2G, how to compare it with LM324DR2G and LM2902DR2G, and what information to send when requesting a fast RFQ.
What Is LM224DR2G?
LM224DR2G is an onsemi operational amplifier, single supply, quad device. It includes four amplifier channels in one package and is commonly supplied in SOIC-14. According to onsemi product information, the LM224DR2G family is listed with typical gain bandwidth of 1 MHz, typical slew rate of 0.6 V/us, typical supply current of 0.35 mA and four channels.
Because LM224DR2G is used in many analog signal paths, buyers should avoid replacing it only by package appearance. Even if two parts are both quad op amps in SOIC-14, electrical performance, temperature rating, offset voltage, input common-mode range and approval status may still be different.
LM224DR2G Key Specifications Buyers Should Check
| Parameter | LM224DR2G Buyer Note | Why It Matters |
|---|---|---|
| Manufacturer | onsemi | Confirm the required brand if the BOM or AVL specifies onsemi. |
| Device type | Single-supply quad operational amplifier | Make sure the replacement is also suitable for the same analog circuit function. |
| Package | SOIC-14 | The package must match the PCB footprint and assembly process. |
| Channels | 4 channels | Do not replace with a single or dual op amp unless the design is changed. |
| Typical GBW | 1 MHz class | Gain bandwidth affects signal response and circuit stability. |
| Typical slew rate | 0.6 V/us class | Slew rate matters in signal conditioning and dynamic analog applications. |
| Packing | Check reel, tube or tape-and-reel requirement | Production buyers should confirm the packing format before purchase. |
LM224DR2G vs LM324DR2G vs LM2902DR2G
LM324DR2G and LM2902DR2G are often considered when buyers search for LM224DR2G alternatives. They are also quad operational amplifiers, but they should not be treated as automatic replacements without datasheet comparison and approval.
| Part Number | Type | Package | Buyer Notes |
|---|---|---|---|
| LM224DR2G | Quad operational amplifier | SOIC-14 | Main target part. Confirm onsemi brand, stock, lead time, date code and packing. |
| LM324DR2G | Quad operational amplifier | SOIC-14 | Possible alternative direction. Check voltage range, offset, temperature rating and approval status. |
| LM2902DR2G | Quad operational amplifier | SOIC-14 | Often reviewed for industrial-style applications. Verify datasheet and BOM approval before replacing. |
Can LM324DR2G or LM2902DR2G Replace LM224DR2G?
Sometimes a related quad op amp can be accepted as an alternative, but the decision should not be made by purchasing alone. Engineering approval is important because op amp substitution may affect offset voltage, input bias current, output swing, bandwidth, power consumption, temperature behavior and circuit stability.
Before accepting LM324DR2G or LM2902DR2G as a replacement for LM224DR2G, check the following:
- Full manufacturer part number and suffix
- Package and PCB footprint
- Supply voltage range
- Operating temperature range
- Input offset voltage
- Input bias current
- Gain bandwidth product
- Slew rate
- Output swing and load condition
- RoHS or compliance requirement
- AVL or customer-approved part list
Why Buyers Search for LM224DR2G Stock
LM224DR2G is used in many mature products and maintenance BOMs. Buyers may need this part for production builds, repair projects, replacement boards or urgent shortages. In these situations, a simple price quote is not enough. The supplier should confirm whether the quoted parts match the required manufacturer, package, stock status, date code and packing condition.
For urgent orders, buyers should ask for stock confirmation before placing the order. If the required part is not available, request a controlled alternative list and send it to the engineering team for review.
