CROSS-REFERENCE ALTERNATIVE
LM324SR is a Chinese-manufactured 36V General-Purpose Op-Amp from COSINE (科山芯创) that cross-references to LM324 (TI).
It is a SOP14 device positioned as a domestic-supply option against the imported: shorter lead times, no allocation risk and a stable price for volume production. Because the parts are not pin-identical in every case, the engineering checklist below lists what to verify before you commit.

LM324SR — 36V General-Purpose Op-Amp, alternative to LM324
LM324SR is supplied by Shenzhen Jingteng Electronics (JTDZ Tech) as a domestically sourced option for LM324 (TI). Imported parts in this class are frequently subject to allocation, long lead times and steep price swings. A Chinese-manufactured equivalent removes that exposure: the parts are production-validated in industrial, consumer and automotive designs and ship from stock on a short lead time.
Cross-reference chart — which imported parts does LM324SR replace?
Every imported part number that LM324SR is published as a cross-reference alternative to, per the COSINE (科山芯创) 2025 selection table:
| imported part number | brand | Replaced by (this part) |
|---|---|---|
| LM324 | TI | LM324SR |
Cross-reference means functional equivalence in the same application role. It is not a blanket claim of pin-for-pin identity — confirm package, pinout and the parameters listed below before you release a design change.

What to verify before substituting LM324SR
These are the parameters that decide whether a cross-reference works in practice. Run through the list against the datasheet before releasing a change:
- Supply voltage range including the full 36 V rating
- Gain-bandwidth product and slew rate for your signal bandwidth
- Input offset voltage and bias current tolerance acceptable for the application
- Output current capability into the real load
- Input common-mode range and output swing
- Package/pinout for single, dual and quad variants
- Quiescent current and thermal behaviour in a multi-channel package
Typical applications
- Industrial process control and 4–20 mA loops
- Precision sensor signal conditioning
- Instrumentation and data-acquisition front ends
- Medical and laboratory equipment
- Test and measurement instruments
- Audio and active-filter stages
