Engineering Selection Recommendations
For automotive applications requiring AEC-Q200 compliance, select from the direct substitute group: CRCW060323K2FKEA (Vishay Dale), ERJ-3EKF2322V (Panasonic), RMCF0603FG23K2, or RMCF0603FT23K2 (Stackpole Electronics Inc). All four maintain full automotive qualification and are currently in active production status.
RMCF0603FT23K2 offers the highest inventory availability (419,394 pcs) among AEC-Q200 rated options, supporting high-volume production requirements.
For non-automotive applications where AEC-Q200 certification is not required, CR0603-FX-2322ELF (Bourns) and RC0603FR-0723K2L (YAGEO) are viable alternatives. RC0603FR-0723K2L provides maximum inventory depth (167,692 pcs) for general-purpose applications.
All substitute parts maintain ROHS3 compliance, MSL rating of 1 (Unlimited), and identical electrical and thermal specifications to the original MCR03EZPFX2322.
Frequently Asked Questions (FAQ)
Q: Can I use a non-AEC-Q200 rated substitute in an automotive circuit?
A: No. If the original design specifies AEC-Q200 compliance, substitutes must also carry AEC-Q200 certification. Use only CRCW060323K2FKEA, ERJ-3EKF2322V, RMCF0603FG23K2, or RMCF0603FT23K2 for automotive applications.
Q: Are all substitute parts mechanically compatible with the 0603 footprint?
A: Yes. All listed substitutes use the 0603 (1608 Metric) package with identical footprint dimensions. Physical board layout compatibility is assured.
Q: What is the difference between RMCF0603FG23K2 and RMCF0603FT23K2?
A: Both are Stackpole RMCF series 23.2 kΩ ±1% 0.1W 0603 resistors with identical electrical specifications. The primary difference is packaging: FG uses Cut Tape (CT) while FT uses Cut Tape (CT) & Digi-Reel®. RMCF0603FT23K2 has significantly higher inventory availability.
Q: Do all substitutes have the same temperature coefficient?
A: Yes. All substitute parts maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating range, matching the original MCR03EZPFX2322 specification.
Q: Is RoHS3 compliance maintained across all substitutes?
A: Yes. All listed substitute parts are ROHS3 compliant with MSL rating of 1 (Unlimited), ensuring environmental and regulatory compatibility.
