LM317T-HXY
HXY MOSFET
Needs validationmedium risk
Adjustable regulator in the same package. Requires circuit modification to set 15V output.
Best Alternatives to L7815CV-HXY
L7815CV-HXY is a 15V, 1A fixed linear voltage regulator in a TO-220S package. Finding a direct drop-in replacement is challenging, but several functional alternatives exist with different packages or requiring minor circuit changes.
AI replacement insight
Package riskhigh
Most alternatives have different footprints (D2PAK, TO-220) or mounting (THT).
Electrical riskmedium
One candidate has lower input voltage. Others are comparable but require verification.
Firmware risklow
These are simple linear regulators with no firmware.
Sourcing risklow
The 7815 regulator family is widely available from many manufacturers.
Can it be replaced directly?
Direct replacement for L7815CV-HXY should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Use an adjustable regulator like LM317T-HXY in the same TO-220S package, but modify the PCB to accommodate the different pinout and add setting resistors.
Main risk
The primary risk is physical incompatibility. Most alternatives are not in the TO-220S package, requiring a board respin.
