Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification, select from the following active parts: ERJ-3EKF6801V (Panasonic), RMCF0603FT6K80 (Stackpole), CRCW06036K80FKEA (Vishay Dale), AC0603FR-076K8L (YAGEO), or AF0603FR-076K8L (YAGEO). All maintain full compliance with automotive standards and RoHS3 requirements.

For non-automotive applications where AEC-Q200 certification is not required, CRG0603F6K8 (TE Connectivity), CR0603-FX-6801ELF (Bourns), and RC0603FR-076K8L (YAGEO) are active alternatives meeting all core electrical and mechanical specifications.

CRCW06036K80FKEA offers the highest inventory availability (44,573 pcs) among active direct substitutes with AEC-Q200 rating and is recommended as the primary replacement for the discontinued MCR03EZPFX6801.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with different physical dimensions? A: All listed substitutes use the 0603 (1608 Metric) package. Physical dimensions vary slightly between manufacturers (length 1.55mm to 1.60mm, width 0.80mm to 0.85mm, height 0.50mm to 0.55mm), but these variations remain within standard PCB footprint tolerances for 0603 components and do not affect mechanical compatibility.

Q: Is AEC-Q200 certification required for my application? A: AEC-Q200 certification is mandatory for automotive applications. If your design is for automotive use, select only from parts explicitly rated AEC-Q200: ERJ-3EKF6801V, RMCF0603FT6K80, CRCW06036K80FKEA, AC0603FR-076K8L, or AF0603FR-076K8L. For non-automotive applications, all listed parts are functionally equivalent.

Q: What is the difference between Direct and Similar substitutes? A: Direct substitutes (CRCW06036K80FKEA, CRCW06036K80FKEB, ERJ-3EKF6801V, RMCF0603FT6K80) meet all core specifications without additional features. Similar substitutes (AC0603FR-076K8L, AF0603FR-076K8L, CR0603-FX-6801ELF, RC0603FR-076K8L) include additional features such as moisture resistance or anti-sulfur coating while maintaining full electrical and mechanical compatibility.

Q: Are all substitutes RoHS3 compliant? A: Yes, all listed substitute parts are ROHS3 compliant, matching the original MCR03EZPFX6801 specification.

Q: Which substitute has the best availability? A: CRCW06036K80FKEA (Vishay Dale) has the highest inventory with 44,573 pcs in stock and is actively produced. ERJ-3EKF6801V (Panasonic) also offers strong availability with 317,116 pcs in stock.

Q: Can I mix different manufacturers' parts in the same design? A: Yes. All listed substitutes meet identical electrical specifications (6.8 kΩ ±1%, 0.1W, ±100ppm/°C, -55°C to 155°C). Physical dimension variations are within standard PCB assembly tolerances. Mixing manufacturers is acceptable from an electrical and mechanical standpoint.
