MCR03EZPFX9763 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX9763 is a 976 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, making equivalent substitutes necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX9763 is determined by strict equivalence across the following parameters: resistance value (976 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 environmental compliance (ROHS3, MSL 1). Parts are grouped into two categories: Direct Substitutes (identical electrical and mechanical specifications with AEC-Q200 automotive rating) and Similar Substitutes (identical electrical specifications with moisture-resistant features but without explicit AEC-Q200 designation).

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 compliance, the recommended direct substitutes are CRCW0603976KFKEA (Vishay Dale), ERJ-3EKF9763V (Panasonic Electronic Components), and RMCF0603FT976K (Stackpole Electronics Inc). All three parts maintain active product status with substantial inventory availability and identical electrical specifications to the original MCR03EZPFX9763.

For non-automotive applications or where AEC-Q200 certification is not required, CR0603-FX-9763ELF (Bourns Inc.) and RC0603FR-07976KL (YAGEO) provide equivalent electrical performance with moisture-resistant features and active product status. Both parts offer higher inventory levels than the original component.

MCR03ERTF9763 (Rohm Semiconductor) is electrically equivalent but lacks explicit AEC-Q200 designation and is discontinued, making it unsuitable for new designs despite higher current inventory.

Frequently Asked Questions (FAQ)

Q: Can MCR03EZPFX9763 be replaced with any of these substitute parts in automotive applications?

A: Only CRCW0603976KFKEA, ERJ-3EKF9763V, and RMCF0603FT976K maintain AEC-Q200 automotive certification. CR0603-FX-9763ELF and RC0603FR-07976KL lack this certification and should not be used in automotive designs requiring AEC-Q200 compliance.

Q: Are there dimensional differences between the substitute parts?

A: Minor dimensional variations exist. Vishay Dale CRCW0603976KFKEA measures 0.061" L x 0.033" W with 0.020" max height. Stackpole RMCF0603FT976K measures 0.061" L x 0.031" W with 0.022" max height. Rohm, Panasonic, Bourns, and YAGEO parts measure 0.063" L x 0.031" W with 0.022" max height. All dimensions fall within 0603 package tolerance and are mechanically compatible.

Q: What is the difference between Direct and Similar substitutes?

A: Direct substitutes (Vishay Dale, Panasonic, Stackpole) carry AEC-Q200 automotive certification matching the original part's automotive qualification. Similar substitutes (Bourns, YAGEO) provide identical electrical specifications with moisture-resistant features but without explicit AEC-Q200 designation, suitable for non-automotive or general-purpose applications.

Q: Which substitute offers the best inventory availability?

A: RC0603FR-07976KL (YAGEO) provides the highest inventory at 57,579 pieces, followed by ERJ-3EKF9763V (Panasonic) at 66,193 pieces. Both parts are in active production status.

Q: Are all substitutes ROHS3 compliant?

A: Yes, all substitute parts listed are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original MCR03EZPFX9763 environmental specifications.
