Substitute Part Grouping Explanation
Substitution eligibility for the MCR03EZPFX26R7 is determined by strict equivalence across the following critical parameters:
- Resistance value: 26.7 Ohms
- Tolerance: ±1%
- Power rating: 0.1W (1/10W)
- Package: 0603 (1608 Metric)
- Composition: Thick Film
- Temperature coefficient: ±100ppm/°C
- Operating temperature range: -55°C to 155°C
- RoHS compliance: ROHS3 Compliant
- Moisture sensitivity level: 1 (Unlimited)
All substitute parts listed meet these electrical and mechanical specifications. Direct substitutes maintain identical ratings and certifications. The YAGEO RC0603FR-0726R7L is classified as a similar part due to the absence of explicit AEC-Q200 automotive certification, though it meets all other electrical and physical parameters.

Engineering Selection Recommendations
For applications requiring AEC-Q200 automotive certification, select from the following active parts:
- CRCW060326R7FKEA (Vishay Dale): Active status with 28344 units in stock. Meets all automotive and compliance requirements.
- ERJ-3EKF26R7V (Panasonic Electronic Components): Active status with highest inventory availability at 99935 units. Full AEC-Q200 compliance.
- RMCF0603FT26R7 (Stackpole Electronics Inc): Active status with AEC-Q200 certification. Lower inventory at 2382 units.
For non-automotive applications where AEC-Q200 certification is not required, RC0603FR-0726R7L (YAGEO) is available with 10293 units in stock and meets all electrical and physical specifications.
MCR03ERTF26R7 (Rohm Semiconductor) is available with 4652 units but lacks explicit AEC-Q200 certification despite being from the same manufacturer as the original part.
Frequently Asked Questions (FAQ)
Q: Can MCR03ERTF26R7 replace MCR03EZPFX26R7 in automotive applications?
A: MCR03ERTF26R7 shares the same manufacturer and electrical specifications but does not carry explicit AEC-Q200 automotive certification. For applications requiring automotive compliance, use CRCW060326R7FKEA, ERJ-3EKF26R7V, or RMCF0603FT26R7 instead.
Q: Are all substitute parts physically compatible with the original PCB footprint?
A: All parts use the 0603 (1608 Metric) package. Physical dimensions vary slightly between manufacturers (length ranges from 0.061" to 0.063", height from 0.020" to 0.022"), but these variations remain within standard 0603 footprint tolerances and are PCB-compatible.
Q: What is the difference between direct and similar substitutes?
A: Direct substitutes (MCR03ERTF26R7, CRCW060326R7FKEA, ERJ-3EKF26R7V, RMCF0603FT26R7) meet all electrical and mechanical parameters. RC0603FR-0726R7L is classified as similar because it lacks AEC-Q200 automotive certification, though it meets all other specifications.
Q: Which substitute offers the best availability?
A: ERJ-3EKF26R7V (Panasonic) provides the highest inventory at 99935 units while maintaining active product status and full AEC-Q200 compliance.
Q: Are all substitutes RoHS3 compliant?
A: Yes, all listed substitute parts are ROHS3 compliant with MSL rating of 1 (Unlimited).
