Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX14R3 is determined by the following critical parameters:

• Resistance Value: 14.3 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.1W / 1/10W (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)
• Number of Terminations: 2 (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

All substitute parts listed meet these criteria. The ERJ-3EKF14R3V and RMCF0603FT14R3 are classified as direct manufacturer equivalents with full AEC-Q200 automotive rating. The RC0603FR-0714R3L is classified as a similar part with moisture-resistant features but without explicit AEC-Q200 designation.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive compliance, the ERJ-3EKF14R3V (Panasonic) and RMCF0603FT14R3 (Stackpole) are direct equivalents with active product status and full automotive qualification. Both parts are available in high inventory quantities.

The RC0603FR-0714R3L (YAGEO) meets all electrical and mechanical parameters but is designated as moisture-resistant rather than AEC-Q200 rated. Selection of this part should be based on specific application requirements where automotive qualification is not mandatory.

All substitute parts are ROHS3 compliant with MSL 1 rating, matching the original part's environmental and regulatory compliance profile.

Frequently Asked Questions (FAQ)

Q: Can ERJ-3EKF14R3V replace MCR03EZPFX14R3 in automotive applications? A: Yes. The ERJ-3EKF14R3V meets all electrical parameters (14.3 Ohms ±1%, 0.1W) and is AEC-Q200 rated for automotive use with identical operating temperature range (-55°C to 155°C).

Q: What is the difference between the Panasonic and Stackpole substitutes? A: Both ERJ-3EKF14R3V and RMCF0603FT14R3 are direct equivalents with AEC-Q200 automotive rating. Physical dimensions vary slightly (Panasonic: 1.60mm x 0.80mm; Stackpole: 1.55mm x 0.80mm), but both fit the 0603 package specification.

Q: Is the YAGEO RC0603FR-0714R3L suitable for automotive applications? A: The RC0603FR-0714R3L meets all electrical and mechanical parameters but carries a moisture-resistant designation instead of AEC-Q200 certification. Use this part only if automotive qualification is not required for your application.

Q: Are all substitutes available in the same packaging format? A: All substitute parts are available in Tape & Reel (TR) packaging. Verify packaging requirements for your procurement process.

Q: Do all parts have the same moisture sensitivity rating? A: Yes. All parts including the original MCR03EZPFX14R3 have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions.
