This part is suitable for general industrial applications requiring standard thick film resistor performance.

AC2010FK-07220RL (YAGEO): This substitute meets all electrical and mechanical requirements of the RC5025F221CS with the additional qualification of AEC-Q200 automotive certification. The 0.75W power rating and identical package footprint ensure direct board-level compatibility. This part is specified for applications requiring automotive-grade component reliability and traceability, while maintaining full compliance with RoHS3 and MSL 1 requirements.

Both substitute parts are Active status components with confirmed inventory availability, ensuring supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-07220RL or AC2010FK-07220RL be used as direct replacements for RC5025F221CS?

A: Yes. Both substitute parts maintain identical resistance (220 Ohms), tolerance (±1%), package format (2010/5025 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3, MSL 1). The increased power rating does not affect form factor or thermal footprint.

Q: What is the difference between RC2010FK-07220RL and AC2010FK-07220RL?

A: Both parts are electrically and mechanically identical. AC2010FK-07220RL carries AEC-Q200 automotive qualification, making it suitable for automotive applications requiring certified component traceability. RC2010FK-07220RL is specified for general industrial use. Selection depends on application requirements.

Q: Does the higher power rating (0.75W vs 0.667W) affect PCB layout or thermal design?

A: No. Both substitute parts use the identical 2010 (5025 Metric) package with matching physical dimensions (0.197" L x 0.098" W, 5.00mm x 2.50mm) and seated height (0.026", 0.65-0.66mm). The higher power rating provides additional thermal margin without changing footprint or thermal characteristics relative to board layout.

Q: Are all three parts moisture resistant?

A: Yes. RC5025F221CS, RC2010FK-07220RL, and AC2010FK-07220RL all feature moisture-resistant thick film construction with MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations for storage or handling.

Q: What compliance certifications apply to these parts?

A: All three parts are ROHS3 compliant and REACH unaffected. AC2010FK-07220RL additionally carries AEC-Q200 automotive certification. All parts maintain identical operating temperature ranges and environmental specifications.
