Substitute Part Grouping Explanation
Substitution eligibility for the MCR03EZPFX6191 is determined by strict equivalence across the following parameters:
- Resistance value: 6.19 kOhms
- 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
- Moisture sensitivity level: 1 (Unlimited)
Parts are classified as Direct equivalents when they maintain AEC-Q200 automotive certification. Parts classified as Similar maintain all electrical and mechanical parameters but may differ in specific feature certifications (such as moisture resistance designation) or packaging format.

Engineering Selection Recommendations
For applications requiring AEC-Q200 automotive certification, direct equivalents are CRCW06036K19FKEA (Vishay Dale), ERJ-3EKF6191V (Panasonic Electronic Components), and RMCF0603FT6K19 (Stackpole Electronics Inc). All three maintain active product status with full compliance to ROHS3 and automotive standards.
For non-automotive applications or where automotive certification is not mandatory, similar parts CR0603-FX-6191ELF (Bourns Inc.), RC0603FR-076K19L (YAGEO), and RC1608F6191CS (Samsung Electro-Mechanics) provide electrical and mechanical equivalence with active availability.
Selection should prioritize parts with active product status to ensure long-term supply chain stability. RMCF0603FT6K19 offers the highest inventory level at 155,731 pieces.
Frequently Asked Questions (FAQ)
Q: Can I use a part without AEC-Q200 certification as a substitute for the MCR03EZPFX6191?
A: Parts without AEC-Q200 certification (CR0603-FX-6191ELF, RC0603FR-076K19L, RC1608F6191CS) maintain identical electrical and mechanical parameters. Substitution eligibility depends on application requirements. Automotive applications requiring AEC-Q200 compliance must use certified equivalents.
Q: Are there dimensional differences between substitute parts?
A: All substitute parts use the 0603 (1608 Metric) package. Minor dimensional variations exist within tolerance: length ranges from 0.061" to 0.063" (1.55mm to 1.60mm), width from 0.031" to 0.033" (0.80mm to 0.85mm), and height from 0.020" to 0.022" (0.50mm to 0.55mm). These variations remain within standard PCB design tolerances for 0603 components.
Q: What is the difference between Direct and Similar substitute classifications?
A: Direct substitutes maintain AEC-Q200 automotive certification identical to the original part. Similar substitutes maintain all electrical and mechanical parameters but lack AEC-Q200 certification or feature moisture resistance designation instead of automotive rating.
Q: Which substitute offers the best supply availability?
A: RMCF0603FT6K19 (Stackpole Electronics Inc) provides the highest inventory at 155,731 pieces, followed by ERJ-3EKF6191V (Panasonic Electronic Components) at 78,419 pieces.
Q: Are all substitutes RoHS3 compliant?
A: All listed substitute parts are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the original MCR03EZPFX6191 specifications.
