CROSS-REFERENCE ALTERNATIVE
COSINA180A3 is a Chinese-manufactured Current-Sense Amplifier from COSINE (科山芯创) that cross-references to INA180A3 (TI).
It is a SOT23-5 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.

COSINA180A3 — Current-Sense Amplifier, alternative to INA180A3
COSINA180A3 is supplied by Shenzhen Jingteng Electronics (JTDZ Tech) as a domestically sourced option for INA180A3 (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 COSINA180A3 replace?
Every imported part number that COSINA180A3 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) |
|---|---|---|
| INA180A3 | TI | COSINA180A3 |
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 COSINA180A3
These are the parameters that decide whether a cross-reference works in practice. Run through the list against the datasheet before releasing a change:
- Gain option and gain error over temperature — check the suffix, different suffixes are different gains
- Common-mode input range: high-side vs low-side sensing, and whether the part survives the bus voltage
- Common-mode rejection ratio at the switching frequency of the load it monitors
- Input offset voltage and drift, the dominant error at low shunt drop
- Bandwidth and settling time for the current waveform you need to capture
- Reference pin configuration and the resulting output offset at zero current
- Package and pinout
Typical applications
- Motor and solenoid current monitoring
- Battery charge/discharge current sensing
- Power-supply overcurrent protection
- DC-DC converter current feedback
- Industrial 4–20 mA current loops
- Energy metering and power monitoring
