Key Parameters

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX53R6 is determined by strict equivalence across the following parameters:

• Resistance value: 53.6 Ohms
• Tolerance: ±1%
• Power rating: 0.1W
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All substitute parts listed meet these electrical and mechanical specifications. Direct substitutes maintain full AEC-Q200 automotive qualification. Similar substitutes meet the core electrical parameters but differ in specific feature certifications (automotive rating or moisture resistance designation).

Parameter Comparison

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification, select from the direct substitutes: CRCW060353R6FKEA (Vishay Dale), ERJ-3EKF53R6V (Panasonic Electronic Components), or RMCF0603FT53R6 (Stackpole Electronics Inc). All three maintain active product status and full automotive compliance.

For non-automotive applications where AEC-Q200 certification is not required, CR0603-FX-53R6ELF (Bourns Inc.) and RC0603FR-0753R6L (YAGEO) are suitable alternatives. Both parts are in active production with high inventory availability.

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-53R6ELF or RC0603FR-0753R6L as direct replacements for MCR03EZPFX53R6 in automotive applications?

A: CR0603-FX-53R6ELF and RC0603FR-0753R6L do not carry AEC-Q200 automotive qualification. Use these parts only in non-automotive applications. For automotive designs, select CRCW060353R6FKEA, ERJ-3EKF53R6V, or RMCF0603FT53R6.

Q: Are all substitute parts available in the same packaging formats?

A: Packaging availability differs by manufacturer. CRCW060353R6FKEA and RMCF0603FT53R6 are supplied in Tape & Reel format. ERJ-3EKF53R6V is available in Cut Tape & Digi-Reel format. Verify packaging requirements with your procurement process.

Q: Do all substitutes meet the same temperature coefficient specification?

A: Yes. All listed substitutes maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating temperature range, matching the original MCR03EZPFX53R6 specification.

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

A: Direct substitutes (CRCW060353R6FKEA, ERJ-3EKF53R6V, RMCF0603FT53R6) maintain AEC-Q200 automotive qualification. Similar substitutes (CR0603-FX-53R6ELF, RC0603FR-0753R6L) meet all electrical and mechanical parameters but lack automotive certification.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the environmental compliance of the original part.
