AI replacement insight

Electrical riskmedium

Voltage matches on best candidates; temp may not.

Package riskmedium

Same package string, but land pattern is not checked.

Firmware riskmedium

Stay within ESP32-C3 to reduce porting risk.

Sourcing riskmedium

1U-H4 has NRND evidence.

Can it be replaced directly?

No verified pin-compatible replacement is supported by the provided data.

Best replacement path

Use ESP32-C3-MINI-1-N4 only if 85C is acceptable; use 1U-H4 only with antenna redesign.

Main risk

Pinout is not verified and the closest parts change either temperature grade or antenna type.
