MCR03EZPFX5363 Equivalent & Substitute Parts
Part Overview
The MCR03EZPFX5363 is a 536 kOhms ±1% 0.1W thick film chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This component is rated for automotive applications under AEC-Q200 standard with an operating temperature range of -55°C to 155°C. The part is currently discontinued at DiGi Electronics, necessitating identification of equivalent alternatives from active manufacturers that maintain identical electrical and mechanical specifications.

Substitute Part Grouping Explanation
Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (536 kOhms), tolerance (±1%), power rating (0.1W), package type (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and RoHS3 compliance. All identified substitutes meet these core electrical and mechanical requirements. Substitute parts are grouped into two categories based on automotive certification status: Direct Substitutes maintain full AEC-Q200 automotive qualification; Similar Substitutes meet all electrical and mechanical parameters but feature moisture-resistant construction without explicit automotive AEC-Q200 rating.

Engineering Selection Recommendations
For applications requiring automotive AEC-Q200 certification, direct substitutes CRCW0603536KFKEA (Vishay Dale), ERJ-3EKF5363V (Panasonic Electronic Components), and RMCF0603FT536K (Stackpole Electronics Inc) are qualified equivalents. All three maintain active product status with full inventory availability. RMCF0603FT536K offers the highest inventory level at 142,690 pieces.
For non-automotive applications or where moisture-resistant construction is specified without AEC-Q200 requirement, CR0603-FX-5363ELF (Bourns Inc.) and RC0603FR-07536KL (YAGEO) are functionally equivalent alternatives. Both parts maintain identical electrical parameters and RoHS3 compliance with active product status.
All substitute parts are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the original MCR03EZPFX5363 specification.
Frequently Asked Questions (FAQ)
Q: Can I use CR0603-FX-5363ELF or RC0603FR-07536KL as direct replacements for MCR03EZPFX5363 in automotive applications?
A: CR0603-FX-5363ELF and RC0603FR-07536KL are not rated for AEC-Q200 automotive qualification. Use these parts only in non-automotive applications or where automotive certification is not required. For automotive applications, select from CRCW0603536KFKEA, ERJ-3EKF5363V, or RMCF0603FT536K.
Q: Are all substitute parts compatible with the 0603 package footprint?
A: Yes. All substitute parts use the 0603 (1608 Metric) package. Physical dimensions vary slightly within tolerance: length ranges from 0.061" to 0.063" (1.55mm to 1.60mm) and height from 0.020" to 0.022" (0.50mm to 0.55mm). These variations are within standard PCB design tolerances for 0603 components.
Q: What is the difference between Direct Substitutes and Similar Substitutes?
A: Direct Substitutes (CRCW0603536KFKEA, ERJ-3EKF5363V, RMCF0603FT536K) carry AEC-Q200 automotive certification matching the original part. Similar Substitutes (CR0603-FX-5363ELF, RC0603FR-07536KL) meet all electrical and mechanical specifications but feature moisture-resistant construction without automotive rating.
Q: Do all substitute parts meet RoHS3 compliance?
A: Yes. All substitute parts listed are ROHS3 compliant with MSL rating of 1 (Unlimited), identical to the original MCR03EZPFX5363.
Q: Which substitute offers the best inventory availability?
A: RMCF0603FT536K from Stackpole Electronics Inc provides the highest inventory level at 142,690 pieces while maintaining AEC-Q200 automotive certification and active product status.
