Key Parameters

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX2803 is determined by strict equivalence across the following parameters: resistance value (280 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, EAR99).

Substitute parts are grouped into two categories:

Direct Substitutes maintain full AEC-Q200 automotive qualification: CRCW0603280KFKEA (Vishay Dale), ERJ-3EKF2803V (Panasonic Electronic Components), and RMCF0603FT280K (Stackpole Electronics Inc).

Similar Substitutes meet all electrical and mechanical specifications but feature moisture-resistant construction instead of automotive AEC-Q200 rating: CR0603-FX-2803ELF (Bourns Inc.) and RC0603FR-07280KL (YAGEO).

Parameter Comparison

Engineering Selection Recommendations

For applications requiring strict automotive AEC-Q200 compliance, select from the direct substitutes: CRCW0603280KFKEA, ERJ-3EKF2803V, or RMCF0603FT280K. All three maintain active product status with substantial inventory availability. ERJ-3EKF2803V offers the highest inventory level at 116094 pieces.

For non-automotive applications or where moisture-resistant construction is acceptable, CR0603-FX-2803ELF and RC0603FR-07280KL are viable alternatives. Both maintain identical electrical specifications and operating temperature range while offering active product status.

All substitute parts are RoHS3 compliant, REACH unaffected, and classified under EAR99 export control, matching the original part's regulatory status.

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-2803ELF or RC0603FR-07280KL as direct replacements for MCR03EZPFX2803 in automotive applications?

A: CR0603-FX-2803ELF and RC0603FR-07280KL do not carry AEC-Q200 automotive qualification. Use these only in non-automotive applications or where automotive certification is not required. For automotive applications, select CRCW0603280KFKEA, ERJ-3EKF2803V, or RMCF0603FT280K.

Q: Are all substitute parts mechanically compatible with the original MCR03EZPFX2803?

A: All substitute parts use the 0603 (1608 Metric) package with identical electrical specifications. Minor dimensional variations exist within tolerance (height ranges from 0.50mm to 0.55mm maximum), but these do not affect PCB assembly compatibility.

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

A: Direct substitutes (CRCW0603280KFKEA, ERJ-3EKF2803V, RMCF0603FT280K) maintain AEC-Q200 automotive qualification. Similar substitutes (CR0603-FX-2803ELF, RC0603FR-07280KL) meet all electrical and mechanical specifications but feature moisture-resistant construction without automotive certification.

Q: Which substitute offers the best inventory availability?

A: ERJ-3EKF2803V from Panasonic Electronic Components provides the highest inventory at 116094 pieces while maintaining full AEC-Q200 compliance and active product status.

Q: Do all substitutes maintain the same temperature coefficient and operating range?

A: Yes. All substitute parts maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating temperature range, matching the original MCR03EZPFX2803 specification.
