Engineering Selection Recommendations
For applications requiring AEC-Q200 automotive qualification, direct substitutes with active product status are:
- CRCW060327K0FKEA (Vishay Dale) — 28599 units in stock
- ERJ-3EKF2702V (Panasonic Electronic Components) — 188063 units in stock
- RMCF0603FT27K0 (Stackpole Electronics Inc) — 59331 units in stock
These parts maintain full automotive compliance and are actively manufactured. All three are ROHS3 compliant with MSL 1 rating.
For applications where AEC-Q200 certification is not mandatory, similar alternatives with active status include CR0603-FX-2702ELF (Bourns Inc.), CRG0603F27K (TE Connectivity Passive Product), and RC0603FR-0727KL (YAGEO). These parts meet all electrical and mechanical specifications and maintain ROHS3 compliance.
Frequently Asked Questions (FAQ)
Q: Can I substitute the MCR03EZPFX2702 with any of the listed parts?
A: Substitution depends on application requirements. All listed parts share identical electrical specifications (27 kOhms ±1%, 0.1W, ±100ppm/°C, -55°C to 155°C). For automotive applications requiring AEC-Q200 certification, use only CRCW060327K0FKEA, ERJ-3EKF2702V, or RMCF0603FT27K0. For non-automotive applications, all seven parts are electrically equivalent.
Q: What is the difference between Direct and Similar substitutes?
A: Direct substitutes (CRCW060327K0FKEA, ERJ-3EKF2702V, RMCF0603FT27K0) maintain AEC-Q200 automotive qualification matching the original part. Similar substitutes (CR0603-FX-2702ELF, CRG0603F27K, RC0603FR-0727KL) meet all electrical and mechanical parameters but lack AEC-Q200 certification.
Q: Are there any dimensional differences between these parts?
A: All parts use the 0603 (1608 Metric) package. Dimensional variations are minimal: length ranges from 0.061" to 0.063" (1.55mm to 1.60mm), width is 0.031" to 0.033" (0.80mm to 0.85mm), and height is 0.020" to 0.022" (0.50mm to 0.55mm). These variations are within standard PCB design tolerances.
Q: Which substitute has the highest inventory availability?
A: ERJ-3EKF2702V (Panasonic Electronic Components) has 188063 units in stock, the highest among all listed alternatives.
Q: Do all substitutes have the same moisture sensitivity rating?
A: Yes, all parts including the original MCR03EZPFX2702 have MSL 1 (Unlimited) rating, indicating no moisture sensitivity concerns during storage and handling.
Q: Are all substitutes RoHS compliant?
A: Yes, all listed parts are ROHS3 compliant, meeting current environmental and hazardous substance restrictions.
