Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX7871 is determined by strict equivalence across the following parameters:

• Resistance value: 7.87 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. Direct substitutes maintain full automotive AEC-Q200 certification. Similar substitutes meet all electrical and mechanical parameters but feature moisture-resistant construction instead of automotive-specific qualification.

Parameter Comparison

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 certification, direct substitutes CRCW06037K87FKEA (Vishay Dale), ERJ-3EKF7871V (Panasonic Electronic Components), and RMCF0603FT7K87 (Stackpole Electronics Inc) are fully qualified replacements. All three maintain active product status with established supply availability.

For non-automotive applications or where moisture-resistant construction is preferred, CR0603-FX-7871ELF (Bourns Inc.) and RC0603FR-077K87L (YAGEO) provide equivalent electrical and mechanical performance. Both are actively manufactured with high inventory levels.

Selection between active substitutes should be based on packaging preference (Tape & Reel or Cut Tape), supply chain availability, and procurement lead times.

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-7871ELF or RC0603FR-077K87L in an automotive AEC-Q200 application?

A: No. These parts feature moisture-resistant construction rather than automotive AEC-Q200 certification. For automotive applications, use CRCW06037K87FKEA, ERJ-3EKF7871V, or RMCF0603FT7K87.

Q: Are all substitute parts physically compatible with the original MCR03EZPFX7871 footprint?

A: Yes. All substitute parts use the 0603 (1608 Metric) package. Physical dimensions vary slightly within standard tolerances (length 1.55mm to 1.60mm, width 0.80mm to 0.85mm, height 0.50mm to 0.55mm), but all are compatible with standard 0603 PCB layouts.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Both are surface-mount packaging formats. Tape & Reel is supplied on continuous carrier tape in reel format for automated assembly. Cut Tape is supplied in shorter tape segments. Selection depends on assembly equipment and order quantity requirements.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original part specifications.

Q: Which substitute has the highest inventory availability?

A: RC0603FR-077K87L (YAGEO) has 200,622 pieces in stock. RMCF0603FT7K87 (Stackpole) has 69,850 pieces. CRCW06037K87FKEA (Vishay Dale) has 53,889 pieces. ERJ-3EKF7871V (Panasonic) has 46,065 pieces.
