AI replacement insight

Electrical riskmedium

2.7Ω or 3.3Ω changes current and gain.

Package risklow

Kept options are 0603 2-terminal parts.

Firmware risklow

Passive part; no firmware impact.

Sourcing risklow

Kept parts are catalog matched and active.

Can it be replaced directly?

No verified drop-in replacement is confirmed from this set.

Best replacement path

Use a 0603 option only if the circuit accepts 2.7Ω or 3.3Ω and power/TCR checks pass.

Main risk

Resistance shift plus power derating and TCR limits.
