Key Parameters

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX15R4 is determined by strict equivalence across the following critical parameters:

• Resistance value: 15.4 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

Direct substitutes maintain all electrical and mechanical specifications. The CRCW060315R4FKEA (Vishay Dale) and ERJ-3EKF15R4V (Panasonic) are direct equivalents with active product status and full AEC-Q200 automotive compliance. The RMCF0603FT15R4 (Stackpole Electronics) is also a direct substitute with active status.

The RC0603FR-0715R4L (YAGEO) is classified as a similar substitute. While it matches all critical electrical parameters and package specifications, it features moisture-resistant composition rather than automotive AEC-Q200 rating, making it suitable for applications where automotive qualification is not mandatory.

Parameter Comparison

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 compliance, select from the direct substitutes: CRCW060315R4FKEA (Vishay Dale), ERJ-3EKF15R4V (Panasonic), or RMCF0603FT15R4 (Stackpole Electronics). All three maintain active product status with full automotive qualification and ROHS3 compliance.

The CRCW060315R4FKEA offers the highest inventory availability (20,475 pcs) and is suitable for high-volume production requirements. The ERJ-3EKF15R4V provides 14,486 pcs in stock with equivalent automotive certification. The RMCF0603FT15R4 maintains lower inventory (2,476 pcs) but remains a qualified direct substitute.

For non-automotive applications where AEC-Q200 certification is not required, the RC0603FR-0715R4L (YAGEO) is electrically and mechanically equivalent with the highest inventory level (39,667 pcs). This option provides cost and availability advantages for general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can I use RC0603FR-0715R4L in place of MCR03EZPFX15R4 in automotive applications?

A: The RC0603FR-0715R4L is not rated for automotive AEC-Q200 applications. Use only CRCW060315R4FKEA, ERJ-3EKF15R4V, or RMCF0603FT15R4 for automotive designs requiring AEC-Q200 compliance.

Q: Are all substitute parts in the same 0603 package?

A: Yes. All listed substitutes use the 0603 (1608 Metric) package with identical electrical specifications and compatible mechanical dimensions for direct PCB replacement.

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

A: Direct substitutes (CRCW060315R4FKEA, ERJ-3EKF15R4V, RMCF0603FT15R4) maintain full AEC-Q200 automotive qualification. The similar substitute (RC0603FR-0715R4L) matches all electrical and package parameters but lacks automotive certification.

Q: Do all substitutes have the same temperature coefficient?

A: Yes. All listed parts maintain ±100ppm/°C temperature coefficient with -55°C to 155°C operating range, ensuring thermal performance equivalence.

Q: Which substitute has the best availability?

A: CRCW060315R4FKEA (Vishay Dale) offers 20,475 pcs in stock. For non-automotive applications, RC0603FR-0715R4L (YAGEO) provides the highest inventory at 39,667 pcs.
