Substitute Part Grouping Explanation
Substitution for the MCR03EZPFX4870 is determined by strict equivalence across the following parameters: resistance value (487 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).
Direct substitutes maintain all electrical and mechanical specifications including AEC-Q200 automotive qualification. Similar substitutes meet all core electrical parameters and package requirements but may differ in specific feature designations (such as moisture resistance classification) while maintaining functional equivalence within the specified operating envelope.

Engineering Selection Recommendations
For applications requiring AEC-Q200 automotive qualification, direct substitutes CRCW0603487RFKEA (Vishay Dale), ERJ-3EKF4870V (Panasonic), and RMCF0603FT487R (Stackpole) are fully equivalent to the MCR03EZPFX4870. All three maintain identical electrical specifications, package dimensions, and automotive compliance ratings.
CR0603-FX-4870ELF (Bourns) and RC0603FR-07487RL (YAGEO) are functionally equivalent for non-automotive or general-purpose applications where AEC-Q200 certification is not required. These parts meet all core electrical and mechanical parameters with active product status and substantial inventory availability.
Selection should prioritize active status parts with adequate inventory. ERJ-3EKF4870V offers the highest inventory level (208834 Pcs) among all options.
Frequently Asked Questions (FAQ)
Q: Can CR0603-FX-4870ELF or RC0603FR-07487RL be used in automotive applications requiring AEC-Q200?
A: No. These parts lack AEC-Q200 certification. For automotive applications, use CRCW0603487RFKEA, ERJ-3EKF4870V, or RMCF0603FT487R.
Q: Are all substitute parts physically compatible with the original MCR03EZPFX4870 footprint?
A: Yes. All listed substitutes use the 0603 (1608 Metric) package with identical termination count (2) and compatible maximum seated heights (0.020" to 0.022").
Q: What is the primary reason for substitution?
A: The MCR03EZPFX4870 is discontinued at DiGi Electronics. Active alternatives with identical specifications are available from multiple manufacturers.
Q: Do all substitutes meet RoHS3 compliance?
A: Yes. All listed parts are ROHS3 compliant and REACH unaffected.
Q: Which substitute offers the best availability?
A: ERJ-3EKF4870V (Panasonic) has the highest inventory at 208834 Pcs with active product status and AEC-Q200 certification.
