Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX22R6 is determined by strict equivalence across the following parameters:

Resistance value: 22.6 Ohms
Tolerance: ±1%
Power rating: 0.1W
Package: 0603 (1608 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C to 155°C
RoHS3 compliance
MSL rating: 1 (Unlimited)

All substitute parts listed meet these core electrical and mechanical specifications. Direct substitutes maintain automotive AEC-Q200 certification or equivalent moisture-resistant characteristics. The MCR03ERTF22R6 (Rohm Semiconductor) is a direct equivalent from the same manufacturer. CRCW060322R6FKEA (Vishay Dale), ERJ-3EKF22R6V (Panasonic), and RMCF0603FT22R6 (Stackpole Electronics) are direct substitutes with AEC-Q200 rating. RC0603FR-0722R6L (YAGEO) is classified as a similar substitute with moisture-resistant characteristics but without explicit AEC-Q200 certification.

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification, select from CRCW060322R6FKEA (Vishay Dale), ERJ-3EKF22R6V (Panasonic), or RMCF0603FT22R6 (Stackpole Electronics). All three are currently in active production with substantial inventory availability.

CRCW060322R6FKEA offers the highest inventory level (15,224 pcs) and maintains full AEC-Q200 compliance with dimensional specifications within tolerance of the original part.

ERJ-3EKF22R6V provides the largest available stock (46,209 pcs) and meets all automotive qualification requirements with identical dimensional characteristics to the original MCR03EZPFX22R6.

RMCF0603FT22R6 is available in moderate quantities (4,495 pcs) and delivers AEC-Q200 certification with compatible package dimensions.

RC0603FR-0722R6L (YAGEO) is suitable for non-automotive applications or where moisture resistance is the primary requirement. This part is widely available (36,988 pcs) but lacks explicit AEC-Q200 certification.

MCR03ERTF22R6 (Rohm Semiconductor) is a direct manufacturer equivalent but is discontinued, making it unsuitable for new procurement.

Frequently Asked Questions (FAQ)

Q: Can I use RC0603FR-0722R6L as a direct replacement for MCR03EZPFX22R6 in automotive applications?

A: RC0603FR-0722R6L meets all electrical and mechanical specifications but lacks AEC-Q200 automotive certification. Use only in non-automotive applications or where automotive qualification is not required.

Q: What is the primary difference between the substitute parts?

A: All substitutes share identical electrical specifications (22.6 Ω, ±1%, 0.1W) and package dimensions (0603). The key differentiator is product status and automotive certification. CRCW060322R6FKEA, ERJ-3EKF22R6V, and RMCF0603FT22R6 maintain AEC-Q200 certification; RC0603FR-0722R6L does not.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within tolerance. CRCW060322R6FKEA measures 0.061" L x 0.033" W with 0.020" max height. ERJ-3EKF22R6V and MCR03EZPFX22R6 measure 0.063" L x 0.031" W with 0.022" max height. RMCF0603FT22R6 measures 0.061" L x 0.031" W with 0.022" max height. All are compatible with 0603 footprints.

Q: Which substitute offers the best availability?

A: ERJ-3EKF22R6V (Panasonic) provides the largest inventory at 46,209 pieces with active production status and full AEC-Q200 compliance.

Q: Can I mix different substitute parts in the same assembly?

A: Yes. All direct substitutes (CRCW060322R6FKEA, ERJ-3EKF22R6V, RMCF0603FT22R6) are electrically and mechanically equivalent and can be used interchangeably within the same design.
