Substitute Part Grouping Explanation

Substitution eligibility for the AF2010JK-073K9L is determined by strict equivalence across the following critical parameters:

• Resistance value: 3.9 kOhms
• Tolerance: ±5%
• Power rating: 0.75W
• Package: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Physical dimensions and termination count
• RoHS3 compliance and MSL rating

The RC2010JK-073K9L meets all these criteria and qualifies as a direct substitute. Both parts are manufactured by YAGEO and share identical electrical performance and mechanical compatibility.
