Key Parameters

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX2263 is determined by strict equivalence across the following parameters: resistance value (226 kOhms), 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 termination count (2). All identified substitutes maintain these electrical and mechanical specifications.

The substitute parts are categorized as follows:

Direct Equivalents (Automotive AEC-Q200 Rated): CRCW0603226KFKEA (Vishay Dale), ERJ-3EKF2263V (Panasonic Electronic Components), and RMCF0603FT226K (Stackpole Electronics Inc) provide full functional equivalence with identical electrical characteristics and automotive qualification.

Similar Equivalents (Moisture Resistant, Non-Automotive Rated): CR0603-FX-2263ELF (Bourns Inc.) and RC0603FR-07226KL (YAGEO) maintain all core electrical parameters and package specifications but feature moisture-resistant construction without explicit AEC-Q200 automotive certification.

Parameter Comparison

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 compliance, select from CRCW0603226KFKEA, ERJ-3EKF2263V, or RMCF0603FT226K. All three maintain full automotive qualification with active product status and equivalent electrical performance.

CRCW0603226KFKEA (Vishay Dale) offers the highest inventory availability at 17,189 pieces and is recommended for high-volume production requirements.

ERJ-3EKF2263V (Panasonic Electronic Components) provides the largest inventory stock at 66,033 pieces, suitable for extended supply chain security.

RMCF0603FT226K (Stackpole Electronics Inc) maintains 60,679 pieces in inventory and represents an established alternative with consistent availability.

For non-automotive applications where AEC-Q200 certification is not required, CR0603-FX-2263ELF (Bourns Inc.) and RC0603FR-07226KL (YAGEO) are functionally equivalent. RC0603FR-07226KL offers exceptional inventory depth at 1,275,601 pieces for applications with high-volume demand.

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-2263ELF or RC0603FR-07226KL as direct replacements for MCR03EZPFX2263 in automotive applications?

A: CR0603-FX-2263ELF and RC0603FR-07226KL are electrically and mechanically equivalent but lack explicit AEC-Q200 automotive certification. Use only in non-automotive applications or where automotive qualification is not a design requirement.

Q: Are all substitute parts pin-compatible with the original MCR03EZPFX2263?

A: Yes. All substitute parts use the 0603 (1608 Metric) package with 2 terminations, ensuring identical PCB footprint and soldering compatibility.

Q: What is the difference between the direct equivalents (CRCW0603226KFKEA, ERJ-3EKF2263V, RMCF0603FT226K)?

A: All three maintain identical electrical specifications and AEC-Q200 automotive rating. Selection should be based on inventory availability, lead time, and supplier preference. Physical dimensions vary slightly within tolerance (length 1.55mm to 1.60mm, height 0.50mm to 0.55mm), but these differences do not affect PCB assembly compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitutes are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the original part's environmental and regulatory compliance.

Q: Which substitute offers the best long-term availability?

A: RC0603FR-07226KL (YAGEO) demonstrates the highest inventory level at 1,275,601 pieces. For automotive-qualified alternatives, ERJ-3EKF2263V (Panasonic) provides 66,033 pieces in stock.
