Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX2260 is determined by strict equivalence across the following parameters:

Resistance value: 226 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
RoHS compliance: ROHS3 Compliant
Moisture sensitivity: MSL 1

Parts are grouped into two categories:

Direct Substitutes meet all electrical and mechanical parameters with automotive AEC-Q200 certification or equivalent thick film construction. These include MCR03ERTF2260 (Rohm Semiconductor), CRCW0603226RFKEA (Vishay Dale), ERJ-3EKF2260V (Panasonic Electronic Components), and RMCF0603FT226R (Stackpole Electronics Inc).

Similar Substitute meets all core electrical and mechanical parameters with moisture-resistant thick film construction but without explicit AEC-Q200 automotive certification. RC0603FR-07226RL (YAGEO) falls into this category.

Engineering Selection Recommendations

For applications requiring automotive AEC-Q200 certification, select from CRCW0603226RFKEA (Vishay Dale), ERJ-3EKF2260V (Panasonic Electronic Components), or RMCF0603FT226R (Stackpole Electronics Inc). All three are currently in active production with substantial inventory availability.

CRCW0603226RFKEA offers the highest inventory level (33616 Pcs) and active product status, making it the primary recommendation for new designs and high-volume procurement.

ERJ-3EKF2260V provides the largest available inventory (54506 Pcs) among all substitutes and maintains full AEC-Q200 compliance.

RMCF0603FT226R delivers AEC-Q200 certification with active status and adequate inventory (16096 Pcs) for standard applications.

MCR03ERTF2260 remains available from the original manufacturer (Rohm Semiconductor) with 2877 Pcs in stock, though it is discontinued and lacks explicit AEC-Q200 designation.

RC0603FR-07226RL (YAGEO) is suitable for non-automotive applications requiring moisture-resistant thick film construction. It maintains active production status with 38328 Pcs available.

Frequently Asked Questions (FAQ)

Q: Can MCR03ERTF2260 replace MCR03EZPFX2260 in automotive applications?

A: MCR03ERTF2260 shares identical electrical specifications (226 Ohms ±1%, 0.1W, ±100ppm/°C, -55°C ~ 155°C) and package (0603). However, MCR03ERTF2260 does not carry explicit AEC-Q200 automotive certification. For automotive designs requiring AEC-Q200 compliance, use CRCW0603226RFKEA, ERJ-3EKF2260V, or RMCF0603FT226R instead.

Q: Are all substitute parts pin-compatible with the original MCR03EZPFX2260?

A: Yes. All substitute parts use the 0603 (1608 Metric) package with 2 terminations, ensuring mechanical and electrical compatibility in PCB layouts designed for the original part.

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

A: Direct substitutes (MCR03ERTF2260, CRCW0603226RFKEA, ERJ-3EKF2260V, RMCF0603FT226R) meet all electrical and mechanical specifications with automotive-grade thick film construction. The similar substitute (RC0603FR-07226RL) meets all core specifications but features moisture-resistant construction without explicit automotive certification, making it suitable for non-automotive applications.

Q: Which substitute offers the best availability?

A: ERJ-3EKF2260V (Panasonic Electronic Components) provides the highest inventory level at 54506 Pcs with active product status. CRCW0603226RFKEA (Vishay Dale) offers 33616 Pcs and RC0603FR-07226RL (YAGEO) provides 38328 Pcs.

Q: Do all substitutes meet RoHS3 compliance?

A: Yes. All listed substitutes are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original MCR03EZPFX2260 specifications.

Q: Can RC0603FR-07226RL be used in automotive applications?

A: RC0603FR-07226RL meets all electrical and mechanical specifications but lacks AEC-Q200 automotive certification. For automotive applications, use CRCW0603226RFKEA, ERJ-3EKF2260V, or RMCF0603FT226R.
