Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX19R6 is determined by strict equivalence across the following critical parameters:

• Resistance value: 19.6 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 to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All substitute parts listed meet these electrical and mechanical specifications. Direct substitutes include automotive-rated AEC-Q200 components from alternative manufacturers. One similar part (RC0603FR-0719R6L) lacks explicit AEC-Q200 automotive certification but maintains all other electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring automotive AEC-Q200 compliance, select from the following active alternatives:

• CRCW060319R6FKEA (Vishay Dale) - Active status with 12,766 units in stock
• ERJ-3EKF19R6V (Panasonic Electronic Components) - Active status with 48,442 units in stock
• RMCF0603FT19R6 (Stackpole Electronics Inc) - Active status with 13,486 units in stock

All three maintain full AEC-Q200 automotive certification and ROHS3 compliance. MCR03ERTF19R6 from Rohm Semiconductor is also available (1,846 units in stock) but is discontinued and lacks explicit AEC-Q200 rating in the provided specifications.

RC0603FR-0719R6L (YAGEO) is an active alternative with moisture-resistant thick film composition. This part meets all electrical and mechanical parameters but does not carry AEC-Q200 automotive certification. Selection of this part should be based on application requirements regarding automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can MCR03ERTF19R6 replace MCR03EZPFX19R6 in automotive applications?

A: MCR03ERTF19R6 shares identical electrical specifications (19.6 Ω, ±1%, 0.1W, ±100ppm/°C, -55°C to 155°C) and package (0603). However, the provided specifications do not list AEC-Q200 certification for this part. For applications requiring automotive qualification, use CRCW060319R6FKEA, ERJ-3EKF19R6V, or RMCF0603FT19R6 instead.

Q: What is the difference between direct substitutes and similar parts?

A: Direct substitutes (MCR03ERTF19R6, CRCW060319R6FKEA, ERJ-3EKF19R6V, RMCF0603FT19R6) meet all electrical and mechanical parameters. RC0603FR-0719R6L is classified as a similar part because it lacks AEC-Q200 automotive certification, though it maintains all other specified parameters.

Q: Are there physical dimension differences between substitute parts?

A: All parts use the 0603 (1608 Metric) package. Minor dimensional variations exist: CRCW060319R6FKEA measures 1.55mm × 0.85mm with 0.50mm maximum seated height, while most others measure 1.60mm × 0.80mm with 0.55mm maximum seated height. These variations are within standard 0603 package tolerances and do not affect PCB footprint compatibility.

Q: Which substitute has the highest inventory availability?

A: ERJ-3EKF19R6V (Panasonic) has the highest inventory with 48,442 units in stock, followed by RMCF0603FT19R6 (Stackpole) with 13,486 units and CRCW060319R6FKEA (Vishay Dale) with 12,766 units.

Q: Can RC0603FR-0719R6L be used in place of the original part?

A: RC0603FR-0719R6L meets all electrical specifications (19.6 Ω, ±1%, 0.1W, ±100ppm/°C, -55°C to 155°C) and package requirements (0603). It is suitable for non-automotive applications or applications where AEC-Q200 certification is not required. For automotive use, select an AEC-Q200 rated alternative.
