Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX2261 is determined by strict equivalence across the following parameters:

• Resistance value: 2.26 kOhms
• 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 level: 1 (Unlimited)

Substitute parts are categorized as follows:

Direct Equivalents (Automotive AEC-Q200 Rated): MCR03ERTF2261, CRCW06032K26FKEA, ERJ-3EKF2261V, RMCF0603FT2K26

Similar Equivalents (Moisture Resistant, Non-Automotive Rated): CR0603-FX-2261ELF, RC0603FR-072K26L

All listed substitutes maintain identical electrical specifications and package dimensions, ensuring functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification, select from the following active parts: CRCW06032K26FKEA (Vishay Dale), ERJ-3EKF2261V (Panasonic Electronic Components), or RMCF0603FT2K26 (Stackpole Electronics Inc). All three maintain full automotive compliance and are currently in active production status.

For non-automotive applications where AEC-Q200 certification is not required, CR0603-FX-2261ELF (Bourns Inc.) and RC0603FR-072K26L (YAGEO) provide functionally equivalent alternatives with moisture-resistant thick film construction and significantly higher inventory availability.

All substitute parts are ROHS3 compliant with MSL 1 rating, ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can MCR03EZPFX2261 be directly replaced with any of the listed substitutes?

A: Yes. All listed parts maintain identical electrical specifications (2.26 kΩ ±1%, 0.1W, ±100ppm/°C) and 0603 package dimensions. Physical dimensions vary slightly between manufacturers but remain within standard 0603 tolerances, ensuring PCB footprint compatibility.

Q: What is the difference between Direct Equivalents and Similar Equivalents?

A: Direct Equivalents (MCR03ERTF2261, CRCW06032K26FKEA, ERJ-3EKF2261V, RMCF0603FT2K26) carry AEC-Q200 automotive qualification. Similar Equivalents (CR0603-FX-2261ELF, RC0603FR-072K26L) feature moisture-resistant construction but lack automotive certification. Selection depends on application requirements.

Q: Are there any dimensional differences between substitute parts?

A: Minor variations exist within standard 0603 tolerances. Length ranges from 0.061" to 0.063" (1.55mm to 1.60mm), width from 0.031" to 0.033" (0.80mm to 0.85mm), and height from 0.020" to 0.022" (0.50mm to 0.55mm). All variations remain within 0603 package specification and are compatible with standard PCB footprints.

Q: Which substitute offers the best inventory availability?

A: RC0603FR-072K26L (YAGEO) provides the highest inventory at 228,759 pieces. RMCF0603FT2K26 (Stackpole Electronics Inc) offers 216,337 pieces with AEC-Q200 certification. ERJ-3EKF2261V (Panasonic) provides 115,193 pieces with automotive qualification.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting standard environmental and manufacturing requirements.
