Parameter Comparison

Engineering Selection Recommendations

RMCF0201FT1K91 (Stackpole Electronics Inc): This substitute maintains full electrical and mechanical compatibility with the CRCW02011K91FNED. The component carries AEC-Q200 automotive qualification rating and is RoHS3 compliant. Seated height is 0.011" (0.28mm), which is 0.001" higher than the main part but remains within standard PCB assembly tolerances for 0201 packages. This part is suitable for applications requiring automotive-grade reliability.

ERJ-1GNF1911C (Panasonic Electronic Components): This substitute meets all electrical specifications and maintains identical package dimensions. The operating temperature range is -55°C ~ 125°C, which is 30°C lower than the main part's upper limit. This part is suitable for applications where the maximum operating temperature does not exceed 125°C. RoHS3 compliance and MSL 1 rating are maintained.

Frequently Asked Questions (FAQ)

Q: Can RMCF0201FT1K91 be used as a direct replacement for CRCW02011K91FNED?

A: Yes. Both parts share identical electrical specifications (1.91 kOhms ±1%, 0.05W, ±200ppm/°C) and package format (0201). The seated height difference of 0.001" is within standard PCB assembly tolerances for this package class.

Q: What is the key difference between ERJ-1GNF1911C and the main part?

A: The operating temperature range differs. ERJ-1GNF1911C operates from -55°C to 125°C, while CRCW02011K91FNED operates to 155°C. Select ERJ-1GNF1911C only if your application maximum temperature does not exceed 125°C.

Q: Are all three parts RoHS3 compliant?

A: Yes. CRCW02011K91FNED, RMCF0201FT1K91, and ERJ-1GNF1911C are all RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes, provided the application temperature range does not exceed 125°C. All three parts are 0201 package format with identical footprints and electrical characteristics within specified tolerances.

Q: What does AEC-Q200 rating on RMCF0201FT1K91 indicate?

A: AEC-Q200 is an automotive qualification standard. This rating indicates the part meets automotive industry reliability and quality requirements and is suitable for automotive applications.
