MCR03EZPFX7680 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX7680 is a 768 Ohms ±1% 0.1W chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This thick film resistor meets automotive AEC-Q200 qualification standards and operates across -55°C to 155°C. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX7680 is determined by strict equivalence across the following parameters: resistance value (768 Ohms), 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. The CRCW0603768RFKEA (Vishay Dale), ERJ-3EKF7680V (Panasonic), and RMCF0603FT768R (Stackpole) are direct equivalents with identical or equivalent dimensional tolerances and automotive AEC-Q200 qualification.

The RC0603FR-07768RL (YAGEO) is classified as a similar substitute. While it matches all core electrical parameters and package specifications, it features moisture-resistant construction rather than automotive AEC-Q200 certification, making it suitable for applications where moisture resistance is prioritized over automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 certification, select from the direct substitutes: CRCW0603768RFKEA (Vishay Dale), ERJ-3EKF7680V (Panasonic), or RMCF0603FT768R (Stackpole). All three maintain full compliance with automotive qualification standards and are currently in active production with substantial inventory availability.

The ERJ-3EKF7680V offers the highest inventory level (78,934 pieces) and identical dimensional specifications to the original MCR03EZPFX7680. The CRCW0603768RFKEA provides the largest stock position (24,147 pieces) with tape and reel packaging. The RMCF0603FT768R (46,102 pieces) represents a mid-range inventory option.

For non-automotive applications where moisture resistance is the primary concern, the RC0603FR-07768RL (YAGEO) is suitable. This part maintains all electrical specifications and RoHS3 compliance but lacks automotive AEC-Q200 certification. Inventory availability is highest at 124,839 pieces.

All substitute parts are RoHS3 compliant and REACH unaffected, matching the environmental compliance profile of the original component.

Frequently Asked Questions (FAQ)

Q: Can I use RC0603FR-07768RL in place of MCR03EZPFX7680 in automotive applications?

A: No. The RC0603FR-07768RL lacks AEC-Q200 automotive qualification. Use only CRCW0603768RFKEA, ERJ-3EKF7680V, or RMCF0603FT768R for automotive applications.

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

A: Yes. All substitutes use the 0603 (1608 Metric) package with identical termination count (2) and compatible dimensional specifications. Pad layouts remain unchanged.

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

A: Direct substitutes (CRCW0603768RFKEA, ERJ-3EKF7680V, RMCF0603FT768R) maintain AEC-Q200 automotive certification. The similar substitute (RC0603FR-07768RL) features moisture-resistant construction but lacks automotive qualification.

Q: Do all substitutes meet the same temperature coefficient specification?

A: Yes. All listed substitutes maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating range.

Q: Which substitute has the best availability?

A: RC0603FR-07768RL (YAGEO) has the highest inventory at 124,839 pieces. For automotive-qualified parts, ERJ-3EKF7680V (Panasonic) offers 78,934 pieces.

Q: Are there any dimensional differences between substitutes?

A: Minor variations exist within tolerance. MCR03EZPFX7680 and ERJ-3EKF7680V measure 0.063" L × 0.031" W. CRCW0603768RFKEA and RMCF0603FT768R measure 0.061" L × 0.031" W. All are within 0603 package specification and functionally equivalent for PCB assembly.
