Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX11R3 is determined by the following critical parameters:

Primary Substitution Criteria:

• Resistance value: 11.3 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.1W / 1/10W (exact match required)
• Package: 0603 (1608 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Secondary Compliance Criteria:

• RoHS3 compliance (required for environmental standards)
• Moisture Sensitivity Level 1 (required for storage and handling)

Parts are classified as direct substitutes when all primary criteria are met. The CRCW060311R3FKEA, ERJ-3EKF11R3V, and RMCF0603FT11R3 meet all primary and secondary criteria. The RC0603FR-0711R3L is classified as a similar substitute; it meets all primary electrical and mechanical parameters but features moisture-resistant composition instead of automotive AEC-Q200 rating, making it suitable for non-automotive applications or where moisture resistance is prioritized.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Automotive AEC-Q200 Rated):

The CRCW060311R3FKEA (Vishay Dale), ERJ-3EKF11R3V (Panasonic), and RMCF0603FT11R3 (Stackpole) are direct functional equivalents to the MCR03EZPFX11R3. All three maintain AEC-Q200 automotive qualification, identical electrical specifications, and active product status. Selection among these three should be based on availability and supply chain requirements. The ERJ-3EKF11R3V offers the highest inventory availability at 147,141 pieces.

Similar Substitute (Non-Automotive Applications):

The RC0603FR-0711R3L (YAGEO) meets all electrical and mechanical parameters but is rated for moisture resistance rather than automotive AEC-Q200 compliance. This part is suitable for applications where automotive qualification is not required but moisture resistance is beneficial.

Frequently Asked Questions (FAQ)

Q: Can I use RC0603FR-0711R3L as a direct replacement for MCR03EZPFX11R3 in automotive applications?

A: No. The RC0603FR-0711R3L is rated for moisture resistance, not automotive AEC-Q200 compliance. For automotive applications, use CRCW060311R3FKEA, ERJ-3EKF11R3V, or RMCF0603FT11R3.

Q: Are all substitute parts available in the same packaging format?

A: The substitute parts CRCW060311R3FKEA, ERJ-3EKF11R3V, and RMCF0603FT11R3 are supplied in Tape & Reel (TR) format. The original MCR03EZPFX11R3 packaging format was not specified in the documentation.

Q: What determines if a part can substitute for the MCR03EZPFX11R3?

A: Substitution requires exact matching of resistance (11.3 Ohms), tolerance (±1%), power rating (0.1W), package (0603), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). For automotive use, AEC-Q200 rating is mandatory.

Q: Why is the MCR03EZPFX11R3 discontinued?

A: The part is discontinued at DiGi Electronics. Active alternatives from other manufacturers provide equivalent functionality and compliance.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All listed substitute parts are ROHS3 compliant and have Moisture Sensitivity Level 1 (Unlimited), matching the original part's environmental specifications.
