Key Parameters

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX4120 is determined by strict equivalence across the following parameters: resistance value (412 Ohms), 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, REACH Unaffected, EAR99).

Direct substitutes maintain all electrical and mechanical specifications. The CRCW0603412RFKEA (Vishay Dale), ERJ-3EKF4120V (Panasonic), RMCF0603FG412R (Stackpole), and RMCF0603FT412R (Stackpole) are classified as direct equivalents with active product status and full AEC-Q200 automotive qualification.

The RC0603FR-07412RL (YAGEO) is classified as a similar substitute. While it matches all critical electrical parameters and package specifications, it is rated for moisture-resistant applications rather than full automotive AEC-Q200 qualification, making it suitable for non-automotive or general-purpose applications where automotive certification is not required.

Parameter Comparison

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 certification, select from the direct substitutes: CRCW0603412RFKEA, ERJ-3EKF4120V, RMCF0603FG412R, or RMCF0603FT412R. All four maintain full compliance with automotive standards and RoHS3 requirements. These parts are currently in active production status with substantial inventory availability.

For non-automotive or general-purpose applications where automotive certification is not a design requirement, the RC0603FR-07412RL offers an alternative with equivalent electrical performance and moisture-resistant characteristics.

Selection between direct substitutes should be based on supply chain availability, packaging format (all available in Tape & Reel), and procurement lead times. All direct substitutes are electrically and mechanically interchangeable with the original MCR03EZPFX4120.

Frequently Asked Questions (FAQ)

Q: Can I use RC0603FR-07412RL in place of MCR03EZPFX4120 in an automotive application?

A: The RC0603FR-07412RL is not rated for AEC-Q200 automotive qualification. Use only if your application does not require automotive certification. For automotive designs, use CRCW0603412RFKEA, ERJ-3EKF4120V, RMCF0603FG412R, or RMCF0603FT412R.

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 footprint dimensions and two terminations. Physical board compatibility is maintained across all listed substitutes.

Q: What is the difference between RMCF0603FG412R and RMCF0603FT412R?

A: Both parts are manufactured by Stackpole Electronics with identical electrical specifications, resistance value, tolerance, power rating, and package. The difference lies in the internal film type designation (FG vs. FT), but both meet the same performance parameters and AEC-Q200 requirements.

Q: Do all substitutes meet RoHS3 compliance?

A: Yes. All listed substitutes are ROHS3 compliant and REACH unaffected, matching the compliance profile of the original MCR03EZPFX4120.

Q: Which substitute has the highest inventory availability?

A: RC0603FR-07412RL (YAGEO) has the highest inventory at 370,954 pieces. Among AEC-Q200 rated substitutes, RMCF0603FT412R (Stackpole) has 74,548 pieces available.
