HLW8110
Hiliwei Tech
Needs validationmedium risk
HLW8110 is a close functional metering candidate, but pinout and UART details need review.
Best Alternatives to HLW8032
HLW8032 is a 5 V UART SOP-8 energy metering IC. Alternatives need careful pinout, protocol, and calibration review.
AI replacement insight
Electrical riskmedium
voltage and metering ranges must be checked
Package riskmedium
SOP-8 matches several parts, but pins may not
Firmware riskhigh
UART and pulse-output parts differ
Sourcing risklow
kept parts are catalog matched
Can it be replaced directly?
No direct replacement is verified from the provided evidence.
Best replacement path
Start with HLW8110 for a same-maker UART metering review.
Main risk
Pinout and UART/register compatibility are not proven.
