Substitute Part Grouping Explanation
Substitution eligibility for the MCR03EZPFX2670 is determined by strict equivalence across the following parameters:
- Resistance value: 267 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 ~ 155°C
- RoHS compliance: ROHS3 Compliant
- Moisture sensitivity level: 1 (Unlimited)
Parts are classified as Direct Substitutes when they meet all electrical and mechanical parameters with AEC-Q200 automotive certification. Parts classified as Similar Substitutes meet all core electrical and mechanical parameters but lack AEC-Q200 automotive certification, featuring moisture-resistant construction instead.

Engineering Selection Recommendations
For automotive applications requiring AEC-Q200 compliance, direct substitutes CRCW0603267RFKEA (Vishay Dale), ERJ-3EKF2670V (Panasonic Electronic Components), and RMCF0603FT267R (Stackpole Electronics Inc) are qualified replacements. All three maintain identical electrical specifications, temperature performance, and automotive certification status.
For non-automotive applications or where automotive certification is not mandated, CR0603-FX-2670ELF (Bourns Inc.) and RC0603FR-07267RL (YAGEO) provide functional equivalence with moisture-resistant construction and active product status.
All substitute parts are ROHS3 compliant with MSL 1 rating, ensuring compatibility with standard manufacturing and storage conditions.
Frequently Asked Questions (FAQ)
Q: Can I use CR0603-FX-2670ELF or RC0603FR-07267RL in automotive applications originally designed for MCR03EZPFX2670?
A: These parts lack AEC-Q200 automotive certification. Use only if your application does not require automotive qualification. For automotive designs, select from CRCW0603267RFKEA, ERJ-3EKF2670V, or RMCF0603FT267R.
Q: Are there dimensional differences between the substitute parts?
A: All parts use the 0603 (1608 Metric) package. Minor dimensional variations exist within standard tolerances: length ranges from 0.061" to 0.063" (1.55mm to 1.60mm), width is 0.031" to 0.033" (0.80mm to 0.85mm), and height ranges from 0.020" to 0.022" (0.50mm to 0.55mm). These variations do not affect PCB footprint compatibility.
Q: What is the difference between Direct and Similar substitutes?
A: Direct substitutes (CRCW0603267RFKEA, ERJ-3EKF2670V, RMCF0603FT267R) carry AEC-Q200 automotive certification matching the original part. Similar substitutes (CR0603-FX-2670ELF, RC0603FR-07267RL) meet all electrical and mechanical specifications but feature moisture-resistant construction without automotive certification.
Q: Which substitute has the highest inventory availability?
A: ERJ-3EKF2670V from Panasonic Electronic Components has 164100 pieces in stock, followed by RC0603FR-07267RL from YAGEO with 88282 pieces.
Q: Are all substitutes RoHS3 compliant?
A: Yes, all listed substitute parts are ROHS3 compliant with MSL 1 rating, suitable for standard manufacturing processes.
