Key Parameters

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX7683 is determined by strict equivalence across the following parameters: resistance value (768 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).

Parts are grouped into two categories:

Direct Substitutes maintain full AEC-Q200 automotive qualification: CRCW0603768KFKEA (Vishay Dale), ERJ-3EKF7683V (Panasonic Electronic Components), and RMCF0603FT768K (Stackpole Electronics Inc).

Similar Substitutes meet all electrical and mechanical specifications but feature moisture-resistant construction instead of automotive AEC-Q200 rating: CR0603-FX-7683ELF (Bourns Inc.) and RC0603FR-07768KL (YAGEO).

Parameter Comparison

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 compliance, select from the direct substitutes: CRCW0603768KFKEA, ERJ-3EKF7683V, or RMCF0603FT768K. All three are currently in active production status with substantial inventory availability (25,308 pcs, 54,392 pcs, and 17,368 pcs respectively) and maintain identical electrical specifications and temperature performance to the original MCR03EZPFX7683.

For non-automotive applications or where moisture-resistant construction is acceptable, CR0603-FX-7683ELF and RC0603FR-07768KL are viable alternatives. Both maintain full electrical equivalence and temperature performance while offering higher inventory levels (24,258 pcs and 63,553 pcs respectively).

All substitute parts are RoHS3 compliant, REACH unaffected, and classified under EAR99 export control.

Frequently Asked Questions (FAQ)

Q: Can CR0603-FX-7683ELF or RC0603FR-07768KL be used in automotive applications?

A: These parts meet all electrical and mechanical specifications of the MCR03EZPFX7683 but lack AEC-Q200 automotive qualification. Use only in non-automotive circuits or where automotive qualification is not a design requirement.

Q: Are all substitute parts physically compatible with the original PCB footprint?

A: Yes. All substitute parts use the 0603 (1608 Metric) package. Physical dimensions vary slightly (length 1.55mm to 1.60mm, width 0.80mm to 0.85mm, height 0.50mm to 0.55mm), but these variations are within standard PCB design tolerances for 0603 components.

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

A: Direct substitutes (CRCW0603768KFKEA, ERJ-3EKF7683V, RMCF0603FT768K) maintain AEC-Q200 automotive qualification identical to the original part. Similar substitutes (CR0603-FX-7683ELF, RC0603FR-07768KL) feature moisture-resistant construction and are suitable for general-purpose applications.

Q: Do all substitutes have the same temperature coefficient performance?

A: Yes. All listed substitutes maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating temperature range, ensuring equivalent thermal stability across the specified operating envelope.

Q: Which substitute offers the best inventory availability?

A: RC0603FR-07768KL (YAGEO) provides the highest inventory level at 63,553 pcs. For AEC-Q200 qualified alternatives, ERJ-3EKF7683V (Panasonic) offers 54,392 pcs.
