Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX2612 is determined by strict equivalence across the following parameters:

Resistance value: 26.1 kOhms (exact match required)
Tolerance: ±1% (exact match required)
Power rating: 0.1W / 1/10W (exact match required)
Package: 0603 (1608 Metric) (exact match required)
Composition: Thick Film (exact match required)
Temperature coefficient: ±100ppm/°C (exact match required)
Operating temperature range: -55°C ~ 155°C (exact match required)
RoHS compliance: ROHS3 Compliant (exact match required)
Moisture sensitivity: MSL 1 (exact match required)

All substitute parts listed below meet these criteria. Parts are categorized as Direct Manufacturer Substitutes (functionally and mechanically identical) or Similar Substitutes (meet all electrical and mechanical parameters with minor feature variations).

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification, select from the following active parts:

CRCW060326K1FKEA (Vishay Dale) — Active status with AEC-Q200 certification and highest inventory availability (21,148 units)
ERJ-3EKF2612V (Panasonic Electronic Components) — Active status with AEC-Q200 certification and largest inventory (422,733 units)
RMCF0603FT26K1 (Stackpole Electronics Inc) — Active status with AEC-Q200 certification and substantial inventory (53,115 units)

For applications where AEC-Q200 is not required, CR0603-FX-2612ELF (Bourns Inc.) and RC0603FR-0726K1L (YAGEO) are active alternatives with moisture-resistant features and extensive inventory availability.

MCR03ERTF2612 (Rohm Semiconductor) is a direct manufacturer equivalent but is discontinued, making it unsuitable for new procurement.

Frequently Asked Questions (FAQ)

Q: Can MCR03EZPFX2612 be replaced with any of these substitute parts?

A: Yes, all listed parts meet the electrical and mechanical specifications of the MCR03EZPFX2612. Selection depends on application requirements (AEC-Q200 certification) and availability.

Q: What is the difference between Direct Manufacturer Substitutes and Similar Substitutes?

A: Direct Manufacturer Substitutes (MCR03ERTF2612) are from the same manufacturer and series with identical electrical characteristics. Similar Substitutes are from different manufacturers but meet all specified electrical and mechanical parameters. The primary difference is feature designation (AEC-Q200 certification presence or absence).

Q: Are all substitute parts in 0603 package compatible with the original design?

A: Yes. All substitute parts use the 0603 (1608 Metric) package with identical footprint dimensions (0.063" L x 0.031" W, 1.60mm x 0.80mm). Minor height variations (0.020" to 0.022" seated height) do not affect PCB assembly compatibility.

Q: Which substitute offers the best availability?

A: RC0603FR-0726K1L (YAGEO) has the highest inventory at 756,360 units, followed by ERJ-3EKF2612V (Panasonic) at 422,733 units.

Q: Do all substitutes maintain the same temperature coefficient?

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

Q: Is RoHS3 compliance maintained across all substitutes?

A: Yes. All substitute parts are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating.
