CROSS-REFERENCE ALTERNATIVE
COS1415R is a Chinese-manufactured MOSFET Gate Driver from COSINE (科山芯创) that cross-references to MCP1415RT-E/OT (MICROCHIP), and also to MCP1416RT-E/OT.
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.

COS1415R — MOSFET Gate Driver, alternative to MCP1415RT-E/OT
COS1415R is supplied by Shenzhen Jingteng Electronics (JTDZ Tech) as a domestically sourced option for MCP1415RT-E/OT (MICROCHIP), MCP1416RT-E/OT (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 COS1415R replace?
Every imported part number that COS1415R 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) |
|---|---|---|
| MCP1415RT-E/OT | MICROCHIP | COS1415R |
| MCP1416RT-E/OT | MICROCHIP | COS1415R |
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 COS1415R
These are the parameters that decide whether a cross-reference works in practice. Run through the list against the datasheet before releasing a change:
- Peak source and sink current into the real gate charge — the number that sets switching loss
- Input logic thresholds and compatibility with your 3.3 V or 5 V controller
- Under-voltage lockout (UVLO) thresholds, both rising and falling
- Propagation delay and delay matching between channels, which sets the dead time you must add
- Drive supply range and whether a bootstrap diode or isolated supply is required
- Output stage topology (inverting vs non-inverting, single vs dual channel) and its effect on control polarity
- Package and pinout
Typical applications
- Motor drive and inverter gate drive
- Switch-mode power supplies and DC-DC converters
- Class-D audio output stages
- Solenoid, relay and actuator driving
- Solar micro-inverters and battery chargers
- Industrial automation I/O
