Best Alternatives to RT0402BRD072KL

Package: 0402 (1005 Metric)YageoChip Resistor - Surface MountSeries: RTPackage: Tape & Reel (TR) Cut Tape (CT) Digi-Reel®Resistance: 2 kOhmsTolerance: ±0.1%Temperature Coefficient: ±25ppm/°C

RT0402BRD072KL is a precision 2kΩ, 0.1% tolerance, 25ppm/°C TCR thin film resistor in an 0402 package. Finding a direct drop-in replacement requires matching these tight specifications, while functional alternatives exist in different packages.

AI replacement insight

Electrical riskhigh

High risk if using a same-package thick film part due to worse tolerance and TCR.

Package riskhigh

High risk if selecting a functional alternate, as it requires a PCB redesign.

Can it be replaced directly?

No direct, pin-to-pin replacement with matching precision is available. All same-package options are significant downgrades.

Best replacement path

Functional alternate with PCB change (AR03BTCX2001) for performance, or a parametric downgrade (AC0402FR-072KL) for form factor.

Main risk

The primary risk is a trade-off between maintaining electrical precision (requiring a PCB change) and maintaining the physical footprint (sacrificing precision).

Questions & answers

For electrical performance, Viking Tech's AR03BTCX2001 is a near-perfect match but requires a larger 0603 footprint. If the 0402 package is mandatory, no direct equivalent has been identified, and any substitute like Yageo's AC0402FR-072KL involves a significant precision downgrade.
