CROSS-REFERENCE ALTERNATIVE
COS8042ARZ is a Chinese-manufactured 12V High-Speed Op-Amp from COSINE (科山芯创) that cross-references to AD8042ARZ (ADI).
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.

COS8042ARZ — 12V High-Speed Op-Amp, alternative to AD8042ARZ
COS8042ARZ is supplied by Shenzhen Jingteng Electronics (JTDZ Tech) as a domestically sourced option for AD8042ARZ (ADI). 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 COS8042ARZ replace?
Every imported part number that COS8042ARZ 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) |
|---|---|---|
| AD8042ARZ | ADI | COS8042ARZ |
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 COS8042ARZ
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 range up to 12 V and headroom requirements
- Slew rate and settling time at the required accuracy
- Gain-bandwidth product and phase margin with the real load and stray capacitance
- Output drive current and short-circuit behaviour
- Input capacitance and its loading effect on high-impedance nodes
- Supply current and package thermal limits
- Package and pinout
Typical applications
- Video and imaging signal chains
- Fast ADC/DAC buffer stages
- Active filters on 12 V rails
- Industrial imaging and machine vision
- Pulse and timing circuits
- Cable and line driving
