Engineering Selection Recommendations
Primary Substitutes (Full Compliance Match)
RMCF0603FT2K21, CRCW06032K21FKEA, ERJ-3EKF2211V, and AC0603FR-072K21L are direct equivalents meeting all specifications including AEC-Q200 automotive rating and ROHS3 compliance. These parts are suitable for applications requiring automotive-grade reliability and environmental compliance.
Secondary Substitutes (Compliance Considerations)
CRCW06032K21FKTA is electrically and mechanically equivalent but carries RoHS non-compliant status and REACH Affected designation. This part is suitable only for applications where RoHS3 compliance is not required.
CR0603-FX-2211ELF and RC0603FR-072K21L lack AEC-Q200 automotive certification. These parts are suitable for non-automotive applications where automotive-grade qualification is not mandated.
Inventory Availability
RMCF0603FT2K21 (1,089,176 pcs), ERJ-3EKF2211V (277,921 pcs), and CR0603-FX-2211ELF (129,576 pcs) offer the highest stock levels for immediate procurement.
Frequently Asked Questions (FAQ)
Q: Can RMCF0603FT2K21 replace RMCF0603FG2K21 in automotive applications?
A: Yes. Both parts are manufactured by Stackpole Electronics Inc with identical electrical specifications (2.21 kOhms ±1%, 0.1W), package format (0603), temperature performance (±100ppm/°C, -55°C to 155°C), and AEC-Q200 automotive certification. The parts are functionally interchangeable.
Q: What is the difference between Tape & Reel and Cut Tape packaging?
A: Tape & Reel packaging supplies components on continuous tape suitable for automated pick-and-place assembly. Cut Tape & Digi-Reel packaging provides smaller quantities on cut tape segments. Both formats contain identical components; packaging selection depends on production volume and assembly equipment compatibility.
Q: Is CR0603-FX-2211ELF suitable for automotive applications?
A: CR0603-FX-2211ELF lacks AEC-Q200 automotive certification. While electrically and mechanically equivalent to RMCF0603FG2K21, it is not qualified for automotive applications. Use only in non-automotive circuits.
Q: Why does CRCW06032K21FKTA show RoHS non-compliant status?
A: CRCW06032K21FKTA carries RoHS non-compliant and REACH Affected designations. This part is suitable only for applications where RoHS3 compliance exemptions apply. For RoHS3-compliant designs, use CRCW06032K21FKEA instead.
Q: Are all substitutes rated for -55°C to 155°C operation?
A: Yes. All identified substitute parts maintain the same operating temperature range (-55°C to 155°C) and temperature coefficient (±100ppm/°C) as the original RMCF0603FG2K21.
Q: Can I use multiple substitute parts interchangeably in the same design?
A: Yes, provided compliance requirements are met. For automotive applications, restrict selection to parts with AEC-Q200 certification: RMCF0603FT2K21, CRCW06032K21FKEA, ERJ-3EKF2211V, and AC0603FR-072K21L. For non-automotive applications, all listed parts are electrically compatible.
