Substitute Part Grouping Explanation
Substitution for the MCR03EZPFX1963 is determined by strict equivalence across the following parameters:
- Resistance value: 196 kOhms
- Tolerance: ±1%
- Power rating: 0.1W (1/10W)
- Package: 0603 (1608 Metric)
- Composition: Thick Film
- Temperature coefficient: ±100ppm/°C
- Operating temperature range: -55°C ~ 155°C
- RoHS compliance: ROHS3 Compliant
- Moisture sensitivity: MSL 1
Substitute parts are categorized as follows:
Direct Substitutes maintain all electrical and mechanical parameters with identical or equivalent packaging formats (Cut Tape, Digi-Reel, or Tape & Reel).
Similar Substitutes meet all core electrical specifications and package dimensions but may differ in specific features (such as moisture resistance designation) or have minor dimensional variations within acceptable tolerances.

Engineering Selection Recommendations
For applications requiring automotive AEC-Q200 certification, select from CRCW0603196KFKEA (Vishay Dale), ERJ-3EKF1963V (Panasonic), or RMCF0603FT196K (Stackpole Electronics). All three are currently active products with full AEC-Q200 compliance matching the original MCR03EZPFX1963 specification.
For general industrial applications where AEC-Q200 is not mandatory, CR0603-FX-1963ELF (Bourns) and RC0603FR-07196KL (YAGEO) provide equivalent electrical performance with moisture-resistant characteristics and active product status.
MCR03ERTF1963 (Rohm Semiconductor) is a direct electrical equivalent but shares discontinued status with the original part, making it unsuitable for long-term supply assurance.
All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical operating temperature range (-55°C to 155°C), ensuring direct functional compatibility in existing circuit designs.
Frequently Asked Questions (FAQ)
Q: Can MCR03EZPFX1963 be replaced with any of these substitutes in automotive applications?
A: Direct replacement in automotive applications is limited to parts with AEC-Q200 certification: CRCW0603196KFKEA, ERJ-3EKF1963V, and RMCF0603FT196K. CR0603-FX-1963ELF and RC0603FR-07196KL lack AEC-Q200 rating and are suitable only for non-automotive applications.
Q: Are there dimensional differences between substitute parts?
A: All parts use 0603 (1608 Metric) package. Minor dimensional variations exist within tolerance: CRCW0603196KFKEA measures 1.55mm x 0.85mm with 0.50mm max height, while most others measure 1.60mm x 0.80mm with 0.55mm max height. These variations are within standard PCB design tolerances.
Q: What is the difference between parts marked "Automotive AEC-Q200" and "Moisture Resistant"?
A: AEC-Q200 certification indicates automotive-grade qualification with specific reliability and performance standards. Moisture Resistant designation indicates enhanced protection against moisture ingress but does not imply automotive qualification. Selection depends on application requirements.
Q: Can I use MCR03ERTF1963 as a substitute?
A: MCR03ERTF1963 meets all electrical specifications but is discontinued, creating supply chain risk. Active alternatives are preferred for new designs and ongoing production.
Q: Are all substitutes RoHS3 compliant?
A: Yes. All listed substitutes maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental specifications.
