Key Parameters

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX6493 is determined by strict equivalence across the following parameters: resistance value (649 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 compliance certifications (RoHS3, REACH Unaffected).

Direct substitutes maintain all electrical and mechanical specifications identical to the original part. Similar substitutes meet all core electrical parameters and package requirements but may differ in specific features such as automotive rating or moisture resistance designation.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring automotive-grade components with AEC-Q200 certification, CRCW0603649KFKEA (Vishay Dale), ERJ-3EKF6493V (Panasonic), and RMCF0603FT649K (Stackpole Electronics) are direct functional equivalents with active product status and full compliance certifications.

CR0603-FX-6493ELF (Bourns) and RC0603FR-07649KL (YAGEO) are functionally compatible alternatives that meet all electrical and mechanical specifications. These parts feature moisture-resistant construction and maintain identical electrical performance, though they do not carry explicit AEC-Q200 automotive rating.

All substitute parts are RoHS3 compliant, REACH unaffected, and maintain MSL 1 (unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can CR0603-FX-6493ELF or RC0603FR-07649KL be used in automotive applications? A: These parts meet all electrical and mechanical specifications required for the MCR03EZPFX6493 application. However, they do not carry explicit AEC-Q200 automotive certification. Selection depends on whether your application requires formal automotive qualification.

Q: Are all substitute parts available in the same packaging format? A: All substitute parts are supplied in 0603 (1608 Metric) package. Packaging format (Tape & Reel) is consistent across active alternatives, ensuring compatibility with standard pick-and-place assembly equipment.

Q: What is the difference between direct and similar substitutes? A: Direct substitutes (CRCW0603649KFKEA, ERJ-3EKF6493V, RMCF0603FT649K) maintain AEC-Q200 automotive certification identical to the original part. Similar substitutes (CR0603-FX-6493ELF, RC0603FR-07649KL) meet all electrical parameters but feature moisture-resistant construction without explicit automotive rating.

Q: Are there any dimensional differences between substitute parts? A: Dimensional variations exist within tolerance. The MCR03EZPFX6493, ERJ-3EKF6493V, CR0603-FX-6493ELF, and RC0603FR-07649KL measure 0.063" L x 0.031" W (1.60mm x 0.80mm). CRCW0603649KFKEA and RMCF0603FT649K measure 0.061" L x 0.033" W (1.55mm x 0.85mm) and 0.061" L x 0.031" W (1.55mm x 0.80mm) respectively. All variations remain within 0603 package specification and are PCB footprint compatible.

Q: Do all parts comply with RoHS and REACH regulations? A: All listed substitute parts are RoHS3 compliant and REACH unaffected, matching the original MCR03EZPFX6493 compliance status.
