Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX1871 is determined by strict equivalence across the following parameters:

• Resistance value: 1.87 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)

All substitute parts listed meet these core electrical and mechanical specifications. Direct substitutes maintain full AEC-Q200 automotive qualification. Similar substitutes meet the electrical specifications and RoHS compliance but feature moisture-resistant construction instead of automotive-specific qualification.

Parameter Comparison

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 compliance, select from the direct substitutes: CRCW06031K87FKEA (Vishay Dale), ERJ-3EKF1871V (Panasonic Electronic Components), or RMCF0603FT1K87 (Stackpole Electronics Inc). All three maintain full automotive qualification and are currently in active production with high inventory availability.

For non-automotive applications where AEC-Q200 certification is not required, CR0603-FX-1871ELF (Bourns Inc.) and RC0603FR-071K87L (YAGEO) provide equivalent electrical performance with moisture-resistant construction. These parts are also in active production.

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

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-1871ELF or RC0603FR-071K87L in an automotive application originally designed for MCR03EZPFX1871?

A: These parts meet all electrical specifications but lack AEC-Q200 automotive qualification. Use only if your application does not require automotive-grade certification.

Q: Are all substitute parts available in the same 0603 package?

A: Yes. All listed substitutes use the 0603 (1608 Metric) package with identical electrical specifications and compatible physical dimensions for PCB assembly.

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

A: Direct substitutes (CRCW06031K87FKEA, ERJ-3EKF1871V, RMCF0603FT1K87) maintain AEC-Q200 automotive qualification. Similar substitutes (CR0603-FX-1871ELF, RC0603FR-071K87L) feature moisture-resistant construction but are not automotive-rated.

Q: Do all substitutes have the same temperature coefficient?

A: Yes. All substitute parts maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating range, matching the original MCR03EZPFX1871 specification.

Q: Which substitute has the highest inventory availability?

A: RC0603FR-071K87L (YAGEO) has 168,099 pieces in stock, followed by ERJ-3EKF1871V (Panasonic) with 92,593 pieces and RMCF0603FT1K87 (Stackpole) with 88,805 pieces.
