Substitute Part Grouping Explanation
Substitution for the MCR03EZPFX7870 is determined by strict equivalence across the following parameters: resistance value (787 Ohms), tolerance (±1%), power rating (0.1W), package type (0603), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). All identified substitutes maintain these core electrical and mechanical specifications.
The substitute parts are categorized into two groups:
Direct Equivalents (AEC-Q200 rated): CRCW0603787RFKEA (Vishay Dale), ERJ-3EKF7870V (Panasonic Electronic Components), and RMCF0603FT787R (Stackpole Electronics Inc). These parts maintain full automotive qualification and identical electrical performance.
Similar Equivalents (Moisture Resistant): CR0603-FX-7870ELF (Bourns Inc.) and RC0603FR-07787RL (YAGEO). These parts meet all core electrical and mechanical parameters but feature moisture-resistant construction instead of automotive AEC-Q200 certification.
Parameter Comparison

| ERJ-3EKF7870V | Panasonic Electronic Components | 787 Ω | ±1% | 0.1 | 0603 | ±100ppm/°C | -55°C ~ 155°C | Automotive AEC-Q200 | Active | ROHS3 |
| RMCF0603FT787R | Stackpole Electronics Inc | 787 Ω | ±1% | 0.1 | 0603 | ±100ppm/°C | -55°C ~ 155°C | Automotive AEC-Q200 | Active | ROHS3 |
| CR0603-FX-7870ELF | Bourns Inc. | 787 Ω | ±1% | 0.1 | 0603 | ±100ppm/°C | -55°C ~ 155°C | Moisture Resistant | Active | ROHS3 |
| RC0603FR-07787RL | YAGEO | 787 Ω | ±1% | 0.1 | 0603 | ±100ppm/°C | -55°C ~ 155°C | Moisture Resistant | Active | ROHS3 |
Engineering Selection Recommendations
For applications requiring automotive AEC-Q200 certification, select from the direct equivalents: CRCW0603787RFKEA, ERJ-3EKF7870V, or RMCF0603FT787R. All three maintain active product status and full compliance with automotive standards.
For non-automotive applications or where moisture-resistant construction is preferred, CR0603-FX-7870ELF and RC0603FR-07787RL are suitable alternatives. Both are actively manufactured and ROHS3 compliant.
All substitute parts share identical electrical specifications (787 Ohms ±1%, 0.1W, ±100ppm/°C) and package dimensions (0603), ensuring direct PCB compatibility and circuit performance equivalence.
Frequently Asked Questions (FAQ)
Q: Can I use CR0603-FX-7870ELF or RC0603FR-07787RL in place of MCR03EZPFX7870 in automotive applications?
A: CR0603-FX-7870ELF and RC0603FR-07787RL are not AEC-Q200 rated. Use these only in non-automotive applications or where automotive certification is not required. For automotive designs, select CRCW0603787RFKEA, ERJ-3EKF7870V, or RMCF0603FT787R.
Q: Are all substitute parts physically compatible with the original PCB layout?
A: Yes. All substitute parts use the 0603 (1608 Metric) package with identical termination count (2) and compatible footprint dimensions. Physical PCB compatibility is assured.
Q: What is the difference between direct equivalents and similar equivalents?
A: Direct equivalents (CRCW0603787RFKEA, ERJ-3EKF7870V, RMCF0603FT787R) carry AEC-Q200 automotive certification matching the original part. Similar equivalents (CR0603-FX-7870ELF, RC0603FR-07787RL) meet all electrical and mechanical specifications but feature moisture-resistant construction without automotive qualification.
Q: Do all substitutes meet RoHS compliance?
A: Yes. All listed substitute parts are ROHS3 compliant, matching the original MCR03EZPFX7870 compliance status.
Q: Which substitute has the highest inventory availability?
A: RC0603FR-07787RL (YAGEO) has 86,743 pieces in stock, followed by ERJ-3EKF7870V (Panasonic) with 30,146 pieces and CRCW0603787RFKEA (Vishay Dale) with 20,328 pieces.
