Is there a pin-compatible replacement for HoSRX1206-2W-1mR-1%?

Yes, HoSRX1206-3W-1mR-1% is a pin-compatible replacement. It shares the same 1206 package, 1mΩ resistance, and ±50ppm/°C TCR, with an increased power rating.

What risks should I check before replacing HoSRX1206-2W-1mR-1%?

Ensure the replacement has the same 1206 package, 1mΩ resistance, and a power rating of at least 2W. Also verify the TCR (±50ppm/°C) to maintain circuit accuracy.

HoSRX1206-2W-1mR-1% Alternatives, Datasheet & Cross Reference | Shenzhen Milliohm Electronics Co., Ltd.

HoSRX1206-2W-1mR-1% is a 2W, 1mΩ current sense resistor in a 1206 package. When seeking alternatives, prioritize matching the 1mΩ resistance, 1206 package, and ensuring the power rating is 2W or higher.

AI replacement insight

Electrical risklow

Low if power rating is equal or higher and TCR is matched.

Package riskhigh

High if a non-1206 package is used, requiring board redesign.

Sourcing riskmedium

Specialized low-ohm resistors can have limited availability.

Can it be replaced directly?

Yes, HoSRX1206-3W-1mR-1% from the same manufacturer is a pin-compatible upgrade with a higher 3W power rating.

Best replacement path

The best replacement is HoSRX1206-3W-1mR-1%, which is a direct upgrade with a higher power rating in the same package.

Main risk

The main risk is using a part with a different package size, which requires a PCB redesign, or a part with a weaker TCR.

Recommended alternatives

A direct upgrade with a higher 3W power rating in the same 1206 package and identical electrical characteristics.
