Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX5620 is determined by strict equivalence across the following parameters: resistance value (562 Ohms), tolerance (±1%), power rating (0.1W), package type (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and RoHS3 compliance. Parts are grouped into two categories based on automotive qualification status.

Direct Equivalents (Automotive AEC-Q200 Rated): MCR03ERTF5620, CRCW0603562RFKEA, ERJ-3EKF5620V, and RMCF0603FT562R meet all electrical and mechanical specifications with automotive AEC-Q200 certification, providing full functional and environmental equivalence.

Similar Equivalents (Non-Automotive Rated): CR0603-FX-5620ELF and RC0603FR-07562RL meet all electrical and mechanical specifications but lack automotive AEC-Q200 certification, featuring moisture-resistant thick film composition instead.

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 compliance, select from active-status parts: CRCW0603562RFKEA (Vishay Dale), ERJ-3EKF5620V (Panasonic Electronic Components), or RMCF0603FT562R (Stackpole Electronics Inc). These parts maintain full automotive qualification and are currently in active production with substantial inventory availability.

For non-automotive applications where AEC-Q200 certification is not required, CR0603-FX-5620ELF (Bourns Inc.) and RC0603FR-07562RL (YAGEO) are active alternatives with moisture-resistant thick film composition. RC0603FR-07562RL offers the highest inventory availability at 308,878 pieces.

MCR03ERTF5620 (Rohm Semiconductor) is electrically equivalent but lacks AEC-Q200 certification and is discontinued, making it unsuitable for new designs despite being from the original manufacturer.

Frequently Asked Questions (FAQ)

Q: Can I use a non-AEC-Q200 rated part as a substitute for the MCR03EZPFX5620 in automotive applications?

A: No. The MCR03EZPFX5620 carries AEC-Q200 automotive qualification. For automotive applications, use only AEC-Q200 rated substitutes: CRCW0603562RFKEA, ERJ-3EKF5620V, or RMCF0603FT562R.

Q: Are all substitute parts pin-compatible with the original MCR03EZPFX5620?

A: Yes. All listed substitutes use the 0603 (1608 Metric) package with 2 terminations, ensuring mechanical and electrical pin compatibility on PCBs designed for the original part.

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

A: Direct equivalents (CRCW0603562RFKEA, ERJ-3EKF5620V, RMCF0603FT562R) carry AEC-Q200 automotive certification matching the original part. Similar equivalents (CR0603-FX-5620ELF, RC0603FR-07562RL) meet all electrical and mechanical specifications but lack automotive certification and feature moisture-resistant composition instead.

Q: Why is the MCR03ERTF5620 listed as a substitute if it is discontinued?

A: MCR03ERTF5620 is documented as an equivalent from the original manufacturer but is discontinued at DiGi Electronics. It is included for reference only; active alternatives should be prioritized for new designs and procurement.

Q: Do all substitute parts have the same temperature coefficient and operating range?

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

Q: Which substitute offers the best inventory availability?

A: RC0603FR-07562RL (YAGEO) has the highest inventory at 308,878 pieces. For automotive applications, ERJ-3EKF5620V (Panasonic) offers 132,241 pieces and RMCF0603FT562R (Stackpole) offers 160,806 pieces.
