Substitute Part Grouping Explanation
Substitution for the MCR03EZPFX2870 is determined by strict equivalence across the following parameters: resistance value (287 Ohms), tolerance (±1%), power rating (0.1W), package type (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, REACH Unaffected, EAR99).
Substitute parts are classified into two categories:
Direct Substitutes maintain full AEC-Q200 automotive qualification: CRCW0603287RFKEA (Vishay Dale), ERJ-3EKF2870V (Panasonic Electronic Components), and RMCF0603FT287R (Stackpole Electronics Inc).
Similar Substitutes meet all electrical and mechanical parameters but feature moisture-resistant composition instead of automotive AEC-Q200 rating: CR0603-FX-2870ELF (Bourns Inc.) and RC0603FR-07287RL (YAGEO).

Engineering Selection Recommendations
For automotive applications requiring AEC-Q200 compliance, select from the direct substitute group: CRCW0603287RFKEA, ERJ-3EKF2870V, or RMCF0603FT287R. All three maintain full automotive qualification and ROHS3 compliance. ERJ-3EKF2870V offers the highest inventory availability at 1,162,950 pieces.
For non-automotive applications or where AEC-Q200 certification is not required, CR0603-FX-2870ELF and RC0603FR-07287RL are functionally equivalent alternatives. Both meet all electrical parameters, RoHS3 compliance, and REACH requirements. RC0603FR-07287RL provides higher inventory availability at 71,098 pieces compared to CR0603-FX-2870ELF at 20,041 pieces.
All substitute parts share identical electrical specifications, package dimensions, and environmental compliance ratings with the original MCR03EZPFX2870.
Frequently Asked Questions (FAQ)
Q: Can I use CR0603-FX-2870ELF or RC0603FR-07287RL as direct replacements in automotive applications?
A: These parts meet all electrical and mechanical parameters but lack AEC-Q200 automotive certification. Use only if your application does not require automotive qualification. For automotive designs, select CRCW0603287RFKEA, ERJ-3EKF2870V, or RMCF0603FT287R.
Q: Are all substitute parts physically compatible with the original MCR03EZPFX2870 footprint?
A: Yes. All substitute parts use the 0603 (1608 Metric) package with identical termination count (2) and compatible dimensions. Dimensional variations are within standard manufacturing tolerances and do not affect PCB layout compatibility.
Q: What is the difference between direct substitutes and similar substitutes?
A: Direct substitutes (CRCW0603287RFKEA, ERJ-3EKF2870V, RMCF0603FT287R) maintain AEC-Q200 automotive certification. Similar substitutes (CR0603-FX-2870ELF, RC0603FR-07287RL) meet all electrical specifications but feature moisture-resistant composition without automotive qualification.
Q: Do all substitute parts comply with RoHS and REACH regulations?
A: Yes. All listed substitutes are ROHS3 compliant and REACH unaffected, matching the original MCR03EZPFX2870 compliance status.
Q: Which substitute offers the best inventory availability?
A: ERJ-3EKF2870V (Panasonic Electronic Components) provides the highest inventory at 1,162,950 pieces with active product status.
