Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX2673 is determined by strict equivalence across the following parameters:

• Resistance value: 267 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
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Substitute parts are grouped into two categories based on automotive qualification status:

Direct Equivalents (Automotive AEC-Q200 Rated): MCR03ERTF2673, CRCW0603267KFKEA, ERJ-3EKF2673V, RMCF0603FT267K

Similar Equivalents (Non-Automotive Rated): CR0603-FX-2673ELF, RC0603FR-07267KL

All listed substitutes maintain identical electrical specifications and package dimensions, ensuring mechanical and electrical interchangeability within the defined parameter set.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring automotive AEC-Q200 qualification, select from the following active parts: CRCW0603267KFKEA (Vishay Dale), ERJ-3EKF2673V (Panasonic), or RMCF0603FT267K (Stackpole Electronics). All three maintain full AEC-Q200 compliance and are currently in active production status with substantial inventory availability.

For non-automotive applications where AEC-Q200 certification is not required, CR0603-FX-2673ELF (Bourns) and RC0603FR-07267KL (YAGEO) provide equivalent electrical and mechanical performance. RC0603FR-07267KL offers the highest inventory level at 186,742 pieces.

All substitute parts are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the original part's environmental and regulatory compliance profile.

Frequently Asked Questions (FAQ)

Q: Can MCR03ERTF2673 be used as a direct replacement for MCR03EZPFX2673?

A: MCR03ERTF2673 shares identical electrical specifications (267 kOhms ±1%, 0.1W, 0603 package, ±100ppm/°C, -55°C to 155°C operating range) and RoHS3 compliance. However, the original part carries AEC-Q200 automotive qualification while MCR03ERTF2673 does not list this certification. For automotive applications requiring AEC-Q200 compliance, use CRCW0603267KFKEA, ERJ-3EKF2673V, or RMCF0603FT267K instead.

Q: What is the difference between automotive-rated and non-automotive-rated substitutes?

A: Automotive-rated parts (CRCW0603267KFKEA, ERJ-3EKF2673V, RMCF0603FT267K) meet AEC-Q200 qualification standards for automotive applications. Non-automotive-rated parts (CR0603-FX-2673ELF, RC0603FR-07267KL) meet the same electrical and mechanical specifications but do not carry automotive certification. Selection depends on application requirements.

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

A: Yes. All substitute parts use the 0603 (1608 Metric) package with identical termination count (2) and compatible physical dimensions. Minor variations in height-seated maximum (0.020" to 0.022") and length/width tolerances (1.55mm to 1.60mm) fall within standard PCB assembly tolerances and do not affect mechanical interchangeability.

Q: Which substitute offers the best availability?

A: RC0603FR-07267KL (YAGEO) has the highest inventory at 186,742 pieces. For automotive-qualified alternatives, ERJ-3EKF2673V (Panasonic) offers 61,696 pieces in stock.

Q: Do all substitutes maintain the same temperature coefficient and operating range?

A: Yes. All listed substitutes maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating temperature range, matching the original MCR03EZPFX2673 specification.
