Is there a pin-compatible replacement for AC1210FR-072K4L?

Several resistors share the same 1210 package, making them physically compatible. However, no exact parametric matches were found. All identified candidates have different resistance values or other specification differences and are not direct drop-in replacements.

What risks should I check before replacing AC1210FR-072K4L?

Key risks include: 1) Resistance mismatch (e.g., 2.2kΩ vs. 2.4kΩ), which can alter circuit behavior. 2) Loss of AEC-Q200 qualification, which is critical for automotive use. 3) Downgrades in tolerance (e.g., 5% vs. 1%) or TCR.

AI replacement insight

Electrical riskhigh

Resistance value differences (2.2kΩ vs 2.4kΩ) and potential tolerance/TCR downgrades will alter circuit performance.

Package risklow

Alternatives in the same 1210 package are physically compatible with the PCB layout.

Sourcing riskmedium

The target is an active part; alternatives may have different supply chain characteristics or may not be approved for the application.

Can it be replaced directly?

No direct pin-to-pin replacements have been identified. Alternatives exist with the same 1210 package but have different resistance values or lower specifications, requiring engineering review.

Best replacement path

The best path is to find another AEC-Q200 qualified 1210 resistor with 2.4kΩ resistance, ±1% tolerance, and ≥0.5W power rating from a reputable manufacturer.

Main risk

The primary risks are resistance value mismatch and the lack of AEC-Q200 automotive qualification in most alternatives.

Recommended alternatives

A 1210 resistor with the same power and tolerance, but with a 2.2kΩ resistance and no automotive qualification.
