Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX17R4 is determined by strict equivalence across the following parameters:

• Resistance value: 17.4 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
• Automotive compliance: AEC-Q200
• RoHS compliance: ROHS3

All substitute parts listed meet these exact specifications and are therefore direct functional equivalents suitable for replacement in the same circuit application.

Frequently Asked Questions (FAQ)

Q: Can these substitute parts be used interchangeably with the MCR03EZPFX17R4?

A: Yes. All listed substitutes meet identical electrical and mechanical specifications, including resistance value, tolerance, power rating, package dimensions, temperature coefficient, operating temperature range, and automotive AEC-Q200 qualification. They are direct functional equivalents.

Q: Are there dimensional differences between the main part and substitutes?

A: Minor dimensional variations exist within acceptable tolerances. The MCR03EZPFX17R4 and ERJ-3EKF17R4V share identical dimensions (0.063" L x 0.031" W, 1.60mm x 0.80mm). The CRCW060317R4FKEA and RMCF0603FT17R4 have slightly different length specifications (0.061" vs 0.063") but remain within the 0603 package standard and are mechanically compatible.

Q: What is the significance of the AEC-Q200 rating?

A: AEC-Q200 certification indicates the component meets automotive-grade reliability standards for temperature cycling, moisture resistance, and long-term stability. All substitute parts carry this qualification, ensuring suitability for automotive applications.

Q: Are all substitutes RoHS compliant?

A: Yes. All substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental compliance profile.

Q: Which substitute offers the best availability?

A: ERJ-3EKF17R4V (Panasonic) provides the highest inventory level at 61,461 pieces in stock, followed by CRCW060317R4FKEA (Vishay Dale) at 3,472 pieces.
