Substitute Part Grouping Explanation
Substitution eligibility for the MCR03EZPFX1402 is determined by strict equivalence across the following parameters: resistance value (14 kOhms), tolerance (±1%), power rating (0.1W), package type (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (AEC-Q200, ROHS3, REACH Unaffected).
Direct substitutes maintain all electrical and mechanical specifications identical to the original part. Similar substitutes meet all critical electrical parameters and package requirements but may include additional features such as moisture resistance that do not affect core functionality.

Engineering Selection Recommendations
For applications requiring strict AEC-Q200 automotive compliance, direct substitutes CRCW060314K0FKEA (Vishay Dale), ERJ-3EKF1402V (Panasonic), and RMCF0603FT14K0 (Stackpole Electronics) are fully qualified replacements. All three maintain active product status with substantial inventory availability.
For non-automotive or less stringent applications, similar substitutes AC0603FR-0714KL, CR0603-FX-1402ELF, RC0603FR-0714KL, and RC1608F1402CS provide electrical and mechanical equivalence with ROHS3 compliance. These parts include moisture-resistant features and maintain active production status.
Selection should prioritize parts with active product status and adequate inventory to ensure supply chain continuity. All listed substitutes are ROHS3 compliant and REACH unaffected.
Frequently Asked Questions (FAQ)
Q: Can I use CR0603-FX-1402ELF or RC0603FR-0714KL in place of MCR03EZPFX1402 in automotive applications?
A: CR0603-FX-1402ELF and RC0603FR-0714KL do not carry AEC-Q200 certification. Use only CRCW060314K0FKEA, ERJ-3EKF1402V, or RMCF0603FT14K0 for automotive applications requiring AEC-Q200 compliance.
Q: Are all substitute parts physically compatible with the original PCB layout?
A: Yes. All substitute parts use the 0603 (1608 Metric) package with identical termination count (2) and compatible physical dimensions. Footprint compatibility is maintained across all listed substitutes.
Q: What is the difference between direct and similar substitutes?
A: Direct substitutes (CRCW060314K0FKEA, ERJ-3EKF1402V, RMCF0603FT14K0) maintain identical specifications including AEC-Q200 rating. Similar substitutes meet all electrical and package requirements but lack AEC-Q200 certification or include additional features such as moisture resistance.
Q: Which substitute has the highest inventory availability?
A: RMCF0603FT14K0 from Stackpole Electronics has the highest inventory at 245,184 pieces, followed by RC0603FR-0714KL from YAGEO at 168,606 pieces.
Q: Do all substitutes have the same temperature coefficient?
A: Yes. All listed substitutes maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating temperature range, matching the original MCR03EZPFX1402 specification.
