Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX2052 is determined by strict equivalence across the following parameters:

• Resistance value: 20.5 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. Variations in features (such as automotive AEC-Q200 qualification or moisture resistance) do not disqualify substitution but indicate additional capabilities beyond the base specification.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring automotive qualification, CRCW060320K5FKEA (Vishay Dale), ERJ-3EKF2052V (Panasonic), and RMCF0603FT20K5 (Stackpole Electronics) are active production parts with AEC-Q200 certification matching the original MCR03EZPFX2052 specification.

For general industrial applications without automotive requirements, CR0603-FX-2052ELF (Bourns) and RC0603FR-0720K5L (YAGEO) provide active production alternatives with moisture-resistant characteristics and equivalent electrical performance.

All listed substitutes maintain identical resistance, tolerance, power rating, package dimensions, temperature coefficient, and operating temperature range. Selection should prioritize active production status and compliance with application-specific requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute MCR03EZPFX2052 with any of the listed parts?

A: Yes, all listed parts meet the core electrical and mechanical specifications: 20.5 kOhms ±1%, 0.1W power rating, 0603 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, and ROHS3 compliance. Selection should account for product status (active vs. discontinued/obsolete) and application-specific certifications.

Q: What is the difference between parts with AEC-Q200 and those without?

A: AEC-Q200 certification indicates automotive-grade qualification. Parts with this rating (CRCW060320K5FKEA, ERJ-3EKF2052V, RMCF0603FT20K5) are suitable for automotive applications. Parts without this rating (CR0603-FX-2052ELF, RC0603FR-0720K5L) are suitable for general industrial applications but may not meet automotive procurement requirements.

Q: Are there packaging differences between substitutes?

A: All substitutes use the 0603 (1608 Metric) package. Packaging format varies (Tape & Reel or Cut Tape), but this does not affect electrical or mechanical compatibility. Verify packaging format availability with your supplier for procurement purposes.

Q: Why is MCR03EZPFX2052 discontinued?

A: The original part is discontinued at DiGi Electronics. Multiple active production alternatives from established manufacturers provide equivalent performance and are readily available.

Q: Which substitute has the longest lead time availability?

A: RC0603FR-0720K5L (YAGEO) shows the highest inventory level (5,000,200 pcs), indicating strong availability. ERJ-3EKF2052V (Panasonic) and RMCF0603FT20K5 (Stackpole) also maintain substantial inventory levels.
