Substitute Part Grouping Explanation
Substitution eligibility is determined by the following criteria:
- Resistance Value & Tolerance: All substitute parts must match 523 kOhms ±1%
- Package Dimensions: All parts must be 0201 (0603 Metric) with identical footprint (0.024" L x 0.012" W / 0.60mm x 0.30mm)
- Power Rating: All parts must be rated 0.05W (1/20W)
- Composition: All parts must be thick film construction
- Temperature Coefficient: All parts must be ±200ppm/°C
- Compliance: All parts must be ROHS3 compliant with MSL 1 rating
- Operating Temperature: Parts must support minimum -55°C to 125°C range
The four substitute parts identified below meet all these criteria and are therefore direct functional equivalents for the AC0201FR-07523KL.

Engineering Selection Recommendations
All identified substitute parts are ROHS3 compliant and carry MSL 1 rating, indicating unlimited moisture sensitivity protection. Selection between substitutes should be based on:
Automotive Applications: The AC0201FR-07523KL and RMCF0201FT523K both carry AEC-Q200 automotive qualification. For automotive circuit designs, these two parts are preferred.
Operating Temperature Range: The AC0201FR-07523KL, CRCW0201523KFNED, and RMCF0201FT523K support -55°C to 155°C operation. The RC0201FR-07523KL and ERJ-1GNF5233C are rated to -55°C to 125°C. For applications requiring the full 155°C upper limit, select from the first group.
Physical Height Constraint: The RMCF0201FT523K has a maximum seated height of 0.011" (0.28mm), compared to 0.010" (0.26mm) for other parts. Verify PCB clearance requirements before selection.
Inventory Availability: ERJ-1GNF5233C offers the highest stock level (40,335 units), followed by RC0201FR-07523KL (27,661 units).
Frequently Asked Questions (FAQ)
Q: Can I substitute AC0201FR-07523KL with RC0201FR-07523KL? A: Yes. Both are YAGEO products with identical resistance, tolerance, power rating, and package. The RC0201FR-07523KL operates to 125°C versus 155°C for the AC0201FR-07523KL. Verify your application's maximum operating temperature requirement.
Q: Are all substitute parts suitable for automotive applications? A: Only AC0201FR-07523KL and RMCF0201FT523K carry AEC-Q200 automotive qualification. Other substitutes are suitable for general industrial and consumer applications.
Q: Does the 0.001" height difference between RMCF0201FT523K and other parts affect PCB assembly? A: The RMCF0201FT523K maximum seated height is 0.011" (0.28mm) versus 0.010" (0.26mm) for other parts. This 0.001" difference is within typical PCB assembly tolerances but should be verified against your specific design clearance requirements.
Q: What is the significance of MSL 1 rating? A: MSL 1 indicates unlimited moisture sensitivity protection. All substitute parts can be stored without time or humidity restrictions, simplifying inventory management.
Q: Can I use these substitutes interchangeably in high-temperature circuits? A: For applications exceeding 125°C, use only AC0201FR-07523KL, CRCW0201523KFNED, or RMCF0201FT523K, which are rated to 155°C. The RC0201FR-07523KL and ERJ-1GNF5233C are limited to 125°C maximum.
Q: Are all parts ROHS3 compliant? A: Yes. All listed parts, including the main part and all substitutes, are ROHS3 compliant and REACH unaffected.
