Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX8450 is determined by strict equivalence across the following critical parameters:

• Resistance value: 845 Ohms
• 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
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Direct substitutes maintain all electrical and mechanical specifications. The CRCW0603845RFKEA (Vishay Dale), ERJ-3EKF8450V (Panasonic), and RMCF0603FT845R (Stackpole) are classified as direct equivalents with active product status and full AEC-Q200 automotive qualification.

The RC0603FR-07845RL (YAGEO) is classified as a similar substitute. While it matches all core electrical parameters and package specifications, it features moisture-resistant composition rather than automotive AEC-Q200 certification, making it suitable for applications where automotive qualification is not mandatory.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring automotive-grade components with AEC-Q200 certification, select from the direct substitutes: CRCW0603845RFKEA (Vishay Dale), ERJ-3EKF8450V (Panasonic), or RMCF0603FT845R (Stackpole). All three maintain active product status with full compliance to automotive standards and RoHS3 requirements.

The RC0603FR-07845RL (YAGEO) is suitable for non-automotive applications or designs where automotive qualification is not a contractual or regulatory requirement. This part maintains electrical equivalence and RoHS3 compliance but lacks AEC-Q200 certification.

All substitute parts are available in Tape & Reel (TR) packaging, compatible with standard surface mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Can I use RC0603FR-07845RL as a direct replacement for MCR03EZPFX8450 in automotive applications?

A: No. The RC0603FR-07845RL lacks AEC-Q200 automotive qualification. Use only CRCW0603845RFKEA, ERJ-3EKF8450V, or RMCF0603FT845R for automotive designs requiring AEC-Q200 compliance.

Q: Are all substitute parts available in the same package as the original?

A: Yes. All listed substitutes use the 0603 (1608 Metric) package with identical footprint dimensions, enabling direct PCB layout compatibility.

Q: What is the difference between the direct substitutes?

A: CRCW0603845RFKEA, ERJ-3EKF8450V, and RMCF0603FT845R are electrically and mechanically equivalent. Selection may be based on supplier availability, lead time, or procurement preference. Minor dimensional variations exist within tolerance (see Size / Dimension specifications), but all are compatible with standard 0603 land patterns.

Q: Do all parts meet RoHS3 compliance?

A: Yes. All listed parts, including the original MCR03EZPFX8450, are ROHS3 compliant.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements, simplifying inventory management and reducing production constraints.
