Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification, select from: CRCW06032K80FKEA (Vishay Dale), ERJ-3EKF2801V (Panasonic), or RMCF0603FT2K80 (Stackpole Electronics). These parts maintain full automotive compliance and are in active production with substantial inventory availability.

For non-automotive applications or where AEC-Q200 is not mandated, AC0603FR-072K8L, CR0603-FX-2801ELF, and RC0603FR-072K8L provide equivalent electrical performance with active product status and higher inventory levels.

MCR03ERTF2801 from Rohm Semiconductor is a direct manufacturer equivalent but shares discontinued status with the primary part, limiting its utility for long-term sourcing.

Frequently Asked Questions (FAQ)

Q: Can MCR03EZPFX2801 be directly replaced with any of these substitutes?

A: Yes, all listed parts are electrically and mechanically equivalent. They share identical resistance (2.8 kΩ), tolerance (±1%), power rating (0.1W), package (0603), temperature coefficient (±100ppm/°C), and operating range (-55°C to 155°C). Physical dimensions vary slightly between manufacturers but remain within 0603 package specifications.

Q: Which substitute is best for automotive applications?

A: CRCW06032K80FKEA, ERJ-3EKF2801V, and RMCF0603FT2K80 all carry AEC-Q200 certification. RMCF0603FT2K80 offers the highest inventory (119,187 pcs) and active status. ERJ-3EKF2801V provides the largest stock (112,004 pcs).

Q: Are there packaging differences between substitutes?

A: Yes. MCR03EZPFX2801 and MCR03ERTF2801 use standard 0603 packaging. CRCW06032K80FKEA, ERJ-3EKF2801V, and RMCF0603FT2K80 are supplied in Tape & Reel format. AC0603FR-072K8L, CR0603-FX-2801ELF, and RC0603FR-072K8L also use Tape & Reel. RC0603FR-072K8L is available in Cut Tape & Digi-Reel format. All are compatible with standard pick-and-place assembly equipment.

Q: What is the difference between Direct and Similar substitutes?

A: Direct substitutes (MCR03ERTF2801) are from the same manufacturer series. Similar substitutes are from alternative manufacturers but meet identical electrical specifications. All listed parts are functionally interchangeable based on provided parameters.

Q: Is RoHS compliance consistent across all substitutes?

A: All parts are ROHS3 compliant. REACH status is unaffected for all listed components.
