MCR03EZPFX4873 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX4873 is a 487 kOhms ±1% 0.1W chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This thick film resistor meets automotive AEC-Q200 qualification standards and operates across -55°C to 155°C. The part is currently discontinued at DiGi Electronics, necessitating identification of equivalent alternatives that maintain identical electrical and mechanical specifications for seamless board-level substitution.

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX4873 is determined by strict equivalence across the following parameters:

Resistance value: 487 kOhms
Tolerance: ±1%
Power rating: 0.1W
Package designation: 0603 (1608 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C to 155°C
Termination count: 2
RoHS3 compliance

All identified substitute parts meet these core electrical and mechanical criteria. Direct substitutes maintain automotive AEC-Q200 qualification. The YAGEO RC0603FR-07487KL is classified as a similar substitute due to moisture-resistant feature designation rather than explicit AEC-Q200 automotive rating, though it satisfies all electrical and dimensional requirements.

Engineering Selection Recommendations

For applications requiring automotive AEC-Q200 qualification, select from the three direct substitutes: CRCW0603487KFKEA (Vishay Dale), ERJ-3EKF4873V (Panasonic Electronic Components), or RMCF0603FT487K (Stackpole Electronics Inc). All three maintain active product status with established supply availability.

The YAGEO RC0603FR-07487KL is suitable for non-automotive applications where moisture-resistant thick film composition satisfies design requirements but AEC-Q200 certification is not mandated. This part remains in active production.

All substitute candidates are ROHS3 compliant with MSL 1 rating, ensuring compatibility with standard PCB assembly processes and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can CRCW0603487KFKEA directly replace MCR03EZPFX4873 in automotive applications?

A: Yes. Both parts share identical electrical specifications (487 kOhms ±1%, 0.1W), operate across -55°C to 155°C, and hold AEC-Q200 automotive qualification. The 0603 package footprint is mechanically compatible. CRCW0603487KFKEA is currently in active production with higher inventory availability.

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

A: Direct substitutes (Vishay Dale, Panasonic, Stackpole) carry explicit AEC-Q200 automotive ratings matching the original part. The YAGEO RC0603FR-07487KL is classified as similar because it specifies moisture-resistant composition rather than automotive qualification, though all electrical and dimensional parameters remain equivalent.

Q: Are dimensional variations between substitutes significant?

A: Dimensional variations are within acceptable tolerances for 0603 package footprints. Length ranges from 1.55mm to 1.60mm and height from 0.50mm to 0.55mm. Standard PCB design rules accommodate these variations without requiring layout modifications.

Q: Do all substitutes require identical reflow profiles?

A: All substitutes are thick film 0603 resistors with MSL 1 rating. Standard automotive-grade reflow profiles suitable for AEC-Q200 components apply uniformly across direct substitutes. Verify specific thermal specifications with individual manufacturer datasheets for process optimization.

Q: Can RC0603FR-07487KL be used in automotive designs?

A: RC0603FR-07487KL meets all electrical and thermal specifications but lacks explicit AEC-Q200 certification. Use in automotive applications only if design requirements do not mandate automotive qualification or if equivalent performance under moisture-resistant conditions is validated through design review.
