Matches TCR and technology with better tolerance, but resistance is a standard 220kΩ value.
Viking Tech's ARG03FTC2373 is a precision 0603 thin film resistor with a 237kΩ value and a tight ±25ppm/°C temperature coefficient. Finding an exact drop-in replacement is challenging due to its specific resistance and TCR combination.
Resistance and TCR mismatches require circuit analysis.
All viable candidates are in the same 0603 package.
No, there are no direct drop-in replacements identified that match all key parameters (resistance, tolerance, power, TCR, and technology). All alternatives require a review of design tolerances.
The best path depends on the application's critical parameter. For temperature stability, use a thin film alternative with matching TCR but different resistance. For a closer resistance value, options with a weaker TCR are available.
The primary risk is a change in circuit performance due to differences in resistance value or temperature stability (TCR). The target's ±25ppm/°C TCR is significantly better than many common thick film alternatives.

The best alternative depends on your circuit's sensitivity. Yageo's RT0603BRD07220KL offers matching TCR and better tolerance but with a 220kΩ resistance. Other parts like Fenghua's RS-03K2403FT offer a closer resistance (240kΩ) but with a weaker TCR.
