MCR03EZPFX7873 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX7873 is a 787 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.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX7873 is determined by strict equivalence across the following parameters: resistance value (787 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 termination count (2). All substitute parts listed meet these core electrical and mechanical specifications. Automotive AEC-Q200 rating is present in the main part and three of the four substitutes; one substitute (RC0603FR-07787KL) carries moisture-resistant certification instead but maintains full electrical and thermal compatibility. Physical dimensions may vary within acceptable tolerances for the 0603 package format.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are electrically and mechanically equivalent to the MCR03EZPFX7873 and are suitable for direct replacement. Three substitutes—CRCW0603787KFKEA (Vishay Dale), ERJ-3EKF7873V (Panasonic), and RMCF0603FT787K (Stackpole)—carry active product status and maintain AEC-Q200 automotive certification. The RC0603FR-07787KL (YAGEO) is also active and ROHS3 compliant but features moisture-resistant certification rather than automotive AEC-Q200 rating; this part remains compatible for applications where moisture resistance is beneficial or where automotive certification is not mandatory.

Selection among active substitutes may be based on supply chain availability, packaging format preference (Cut Tape & Digi-Reel versus Tape & Reel), or established supplier relationships. All parts share identical electrical performance characteristics and thermal operating ranges.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for the MCR03EZPFX7873?

A: Yes. All four substitute parts meet the core electrical specifications: 787 kOhms resistance, ±1% tolerance, 0.1W power rating, 0603 package, thick film composition, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Physical dimensions are within acceptable tolerances for the 0603 package format.

Q: What is the difference between the AEC-Q200 rated parts and the RC0603FR-07787KL?

A: CRCW0603787KFKEA, ERJ-3EKF7873V, and RMCF0603FT787K carry AEC-Q200 automotive certification. The RC0603FR-07787KL carries moisture-resistant certification. Both certifications indicate reliability standards; the choice depends on application requirements and whether automotive qualification is specified.

Q: Are there packaging differences I should consider?

A: CRCW0603787KFKEA is supplied in Cut Tape (CT) & Digi-Reel format. ERJ-3EKF7873V, RMCF0603FT787K, and RC0603FR-07787KL are supplied in Tape & Reel (TR) format. Packaging choice affects handling and assembly processes but does not impact electrical performance.

Q: Do all substitutes have the same physical dimensions?

A: Dimensions vary slightly within the 0603 package specification. Length ranges from 0.061" to 0.063" (1.55mm to 1.60mm), width from 0.031" to 0.033" (0.80mm to 0.85mm), and height from 0.020" to 0.022" (0.50mm to 0.55mm). These variations are within standard 0603 tolerances and do not affect PCB layout or assembly compatibility.

Q: Which substitute has the highest inventory availability?

A: ERJ-3EKF7873V (Panasonic) has 171,534 pieces in stock, followed by CRCW0603787KFKEA (Vishay Dale) with 28,155 pieces, RC0603FR-07787KL (YAGEO) with 44,858 pieces, and RMCF0603FT787K (Stackpole) with 66,846 pieces.
