Substitute Part Grouping Explanation
Substitution eligibility for the MCR03EZPFX30R0 is determined by strict equivalence across the following parameters:
- Resistance value: 30 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 core electrical and mechanical parameters. Parts are categorized as Direct Manufacturer equivalents (identical specifications and active product status) or Similar equivalents (meet all core parameters with minor feature variations such as moisture resistance enhancements).

Engineering Selection Recommendations
For applications requiring AEC-Q200 automotive certification, select from the Direct Manufacturer equivalents: CRCW060330R0FKEA (Vishay Dale), ERJ-3EKF30R0V (Panasonic Electronic Components), or RMCF0603FT30R0 (Stackpole Electronics Inc). All three maintain active product status with full AEC-Q200 compliance and ROHS3 certification.
For non-automotive applications or where AEC-Q200 certification is not mandatory, AC0603FR-0730RL, CR0603-FX-30R0ELF, and RC0603FR-0730RL are functionally equivalent alternatives with active availability. AC0603FR-0730RL and RC0603FR-0730RL include moisture-resistant features as additional enhancements.
All substitute parts are available in Tape & Reel (TR) packaging and maintain identical electrical performance within the specified tolerance and temperature operating range.
Frequently Asked Questions (FAQ)
Q: Can MCR03EZPFX30R0 be replaced with any of these substitutes in automotive applications?
A: Only CRCW060330R0FKEA, ERJ-3EKF30R0V, and RMCF0603FT30R0 maintain AEC-Q200 certification required for automotive use. CR0603-FX-30R0ELF and RC0603FR-0730RL do not carry AEC-Q200 ratings and are suitable only for non-automotive applications.
Q: Are there physical dimension differences between the main part and substitutes?
A: All parts use the 0603 (1608 Metric) package. Minor variations exist in seated height (0.020" to 0.022") and length/width dimensions (1.55mm to 1.60mm L, 0.80mm to 0.85mm W), which are within standard 0603 package tolerances and do not affect PCB assembly compatibility.
Q: What is the difference between Direct Manufacturer and Similar equivalents?
A: Direct Manufacturer equivalents (CRCW060330R0FKEA, ERJ-3EKF30R0V, RMCF0603FT30R0) provide identical specifications including AEC-Q200 certification. Similar equivalents (AC0603FR-0730RL, CR0603-FX-30R0ELF, RC0603FR-0730RL) meet all core electrical and mechanical parameters but may lack automotive certification or include additional features such as moisture resistance.
Q: Do all substitutes meet RoHS and REACH compliance requirements?
A: All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the original MCR03EZPFX30R0 specifications.
Q: What inventory levels are available for these substitutes?
A: CRCW060330R0FKEA (60,123 pcs), ERJ-3EKF30R0V (112,386 pcs), RMCF0603FT30R0 (104,906 pcs), AC0603FR-0730RL (193,934 pcs), CR0603-FX-30R0ELF (10,086 pcs), and RC0603FR-0730RL (90,400 pcs) are available as new original stock.
