Substitute Part Grouping Explanation
Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (820 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 (RoHS3, MSL 1).
Substitute parts are categorized as follows:
Upgrade Substitute: KTR03EZPF8203 (Rohm Semiconductor) — Same manufacturer, active product status, identical electrical specifications with additional high voltage feature designation.
Direct Substitutes: CRCW0603820KFKEA (Vishay Dale), ERJ-3EKF8203V (Panasonic Electronic Components), RMCF0603FT820K (Stackpole Electronics Inc) — All meet core electrical and mechanical parameters with active product status and full AEC-Q200 compliance.
Similar Substitutes: CR0603-FX-8203ELF (Bourns Inc.), RC0603FR-07820KL (YAGEO) — Meet all core electrical and mechanical parameters with active product status. Feature designation differs (moisture resistant vs. automotive AEC-Q200), but electrical specifications remain equivalent.

Engineering Selection Recommendations
For applications requiring strict automotive AEC-Q200 compliance, select from: KTR03EZPF8203 (Rohm Semiconductor), CRCW0603820KFKEA (Vishay Dale), ERJ-3EKF8203V (Panasonic Electronic Components), or RMCF0603FT820K (Stackpole Electronics Inc). All four parts maintain identical electrical specifications and full AEC-Q200 qualification.
For non-automotive applications where AEC-Q200 is not mandatory, CR0603-FX-8203ELF (Bourns Inc.) and RC0603FR-07820KL (YAGEO) provide equivalent electrical performance with active product status and RoHS3 compliance. RC0603FR-07820KL offers the highest inventory availability at 125,267 pieces.
All substitute parts are RoHS3 compliant with MSL 1 rating, ensuring compatibility with standard PCB assembly processes.
Frequently Asked Questions (FAQ)
Q: Can MCR03EZPFX8203 be directly replaced with KTR03EZPF8203?
A: Yes. Both parts are manufactured by Rohm Semiconductor with identical electrical specifications (820 kOhms ±1%, 0.1W, 0603 package, ±100ppm/°C, -55°C to 155°C). KTR03EZPF8203 is the active product variant with higher inventory availability.
Q: What is the difference between AEC-Q200 rated and non-AEC-Q200 rated substitutes?
A: AEC-Q200 certification indicates automotive-grade qualification with defined reliability and performance standards. CR0603-FX-8203ELF and RC0603FR-07820KL lack this designation but maintain equivalent electrical parameters. Use AEC-Q200 rated parts for automotive applications; non-AEC-Q200 parts are suitable for industrial and consumer applications.
Q: Are all substitute parts compatible with the 0603 package footprint?
A: Yes. All substitute parts use the 0603 (1608 Metric) package. Physical dimensions vary slightly between manufacturers (length 1.55mm to 1.60mm, width 0.80mm to 0.85mm, height 0.50mm to 0.55mm), but all fit standard 0603 PCB pads without modification.
Q: Which substitute offers the best supply availability?
A: RC0603FR-07820KL (YAGEO) has the highest inventory at 125,267 pieces. RMCF0603FT820K (Stackpole Electronics Inc) offers 83,440 pieces. Both are suitable for high-volume production requirements.
Q: Do all substitutes meet RoHS3 and MSL 1 requirements?
A: Yes. All substitute parts listed are RoHS3 compliant with MSL 1 (unlimited moisture sensitivity level), matching the original MCR03EZPFX8203 specifications.
