CROSS-REFERENCE ALTERNATIVE
COS6042SR is a Chinese-manufactured Nano-Power Op-Amp from COSINE (科山芯创) that cross-references to MCP6042-I/SN (MICROCHIP).
It is a SOP8 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.

COS6042SR — Nano-Power Op-Amp, alternative to MCP6042-I/SN
COS6042SR is supplied by Shenzhen Jingteng Electronics (JTDZ Tech) as a domestically sourced option for MCP6042-I/SN (MICROCHIP). 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 COS6042SR replace?
Every imported part number that COS6042SR 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) |
|---|---|---|
| MCP6042-I/SN | MICROCHIP | COS6042SR |
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 COS6042SR
These are the parameters that decide whether a cross-reference works in practice. Run through the list against the datasheet before releasing a change:
- Quiescent current per channel in the nanoamp region and its temperature coefficient
- Bandwidth at that Iq — nano-power parts have very low GBW; make sure it covers your slowest signal
- Input bias current, its temperature doubling behaviour, and the resulting offset across high source impedances
- Output drive capability, which is very limited at these currents
- Minimum operating supply voltage and start-up behaviour
- Input common-mode range and output swing
- Package and pinout
Typical applications
- Ultra-low-power sensor nodes
- Battery and coin-cell powered devices
- Energy-harvesting systems
- Smoke and gas detectors
- Wireless remote sensors
- Always-on monitoring circuits
