Key Parameters

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX14R7 is determined by strict equivalence across the following parameters: resistance value (14.7 Ohms), tolerance (±1%), power rating (0.1W), package type (0603), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). All substitute parts listed maintain these core electrical and mechanical specifications, ensuring direct functional compatibility in automotive applications.

The substitute parts are grouped into two categories:

Direct Substitutes (Automotive AEC-Q200 Rated): CRCW060314R7FKEA, ERJ-3EKF14R7V, and RMCF0603FT14R7 maintain full automotive qualification and are interchangeable for applications requiring AEC-Q200 compliance.

Similar Substitute (Moisture Resistant, Non-Automotive): RC0603FR-0714L differs in that it carries moisture-resistant specification rather than automotive AEC-Q200 rating, making it suitable for non-automotive applications with equivalent electrical performance.

Parameter Comparison

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 compliance, select from CRCW060314R7FKEA (Vishay Dale), ERJ-3EKF14R7V (Panasonic), or RMCF0603FT14R7 (Stackpole). All three maintain full automotive qualification and are currently in active production status with established supply availability.

For non-automotive applications where AEC-Q200 certification is not required, RC0603FR-0714R7L (YAGEO) provides equivalent electrical performance with moisture-resistant characteristics and the highest inventory availability.

All substitute parts are ROHS3 compliant and carry MSL 1 rating, matching the environmental and regulatory requirements of the original MCR03EZPFX14R7.

Frequently Asked Questions (FAQ)

Q: Can I use RC0603FR-0714R7L as a direct replacement in automotive applications?

A: RC0603FR-0714R7L is not AEC-Q200 rated. For automotive applications requiring AEC-Q200 compliance, use CRCW060314R7FKEA, ERJ-3EKF14R7V, or RMCF0603FT14R7 instead.

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

A: All substitute parts are supplied in 0603 (1608 Metric) package. CRCW060314R7FKEA, ERJ-3EKF14R7V, and RMCF0603FT14R7 are available in Tape & Reel (TR) packaging. Verify packaging requirements with your procurement specification.

Q: What is the difference in physical dimensions between the main part and substitutes?

A: Dimensional variations are minimal. MCR03EZPFX14R7 and ERJ-3EKF14R7V measure 0.063" L x 0.031" W with 0.022" max height. CRCW060314R7FKEA and RMCF0603FT14R7 measure 0.061" L x 0.031" W with 0.020" and 0.022" max heights respectively. These variations are within standard PCB design tolerances for 0603 packages.

Q: Are all parts RoHS compliant?

A: Yes, all listed parts including the original MCR03EZPFX14R7 and all substitutes are ROHS3 compliant.

Q: What is the moisture sensitivity level for these resistors?

A: All parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
