MCR10EZPJ751 Equivalent & Substitute Parts

Part Overview

The MCR10EZPJ751 is a 750 Ohm ±5% 0.125W (1/8W) thick film chip resistor in 0805 (2012 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 MCR10EZPJ751 is determined by the following critical parameters: resistance value (750 Ohms), tolerance (±5%), power rating (0.125W minimum), package type (0805), composition (thick film), and automotive qualification (AEC-Q200). Parts are grouped into three categories based on substitution compatibility:

Direct Equivalents (Identical Specifications): Parts matching all key parameters including 750 Ohm resistance, ±5% tolerance, 0.125W power rating, 0805 package, and AEC-Q200 automotive rating.

Upgrade Substitutes (Enhanced Specifications): Parts with improved electrical characteristics such as higher power ratings (0.4W, 0.5W) or tighter tolerance (±1%), maintaining the same 750 Ohm resistance, 0805 package, and AEC-Q200 rating. These provide superior performance margins.

Similar Alternatives (Non-Automotive Variants): Parts with matching electrical specifications but lacking AEC-Q200 automotive certification, suitable only for non-automotive applications.

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 compliance, select from the active direct equivalents: CRCW0805750RJNEA (Vishay Dale), ERJ-6GEYJ751V (Panasonic), or RMCF0805JT750R (Stackpole Electronics). These parts maintain identical electrical specifications and automotive qualification to the discontinued MCR10EZPJ751.

For applications requiring enhanced performance margins, ESR10EZPJ751 (Rohm Semiconductor, 0.4W) and ERJ-P06J751V (Panasonic, 0.5W) provide higher power ratings while maintaining ±5% tolerance and AEC-Q200 certification. CRCW0805750RFKEA (Vishay Dale) offers tighter ±1% tolerance with reduced temperature coefficient (±100ppm/°C) for precision applications.

CR0805-JW-751ELF (Bourns) is suitable only for non-automotive applications, as it lacks AEC-Q200 certification despite matching electrical specifications.

All recommended substitutes are ROHS3 compliant with MSL 1 rating and identical package dimensions to the original part.

Frequently Asked Questions (FAQ)

Q: Can I use ESR10EZPJ751 as a direct replacement for MCR10EZPJ751?

A: Yes. ESR10EZPJ751 is a direct functional substitute with identical resistance (750 Ω), tolerance (±5%), package (0805), and AEC-Q200 automotive rating. The higher power rating (0.4W vs. 0.125W) provides additional thermal margin without affecting circuit performance.

Q: What is the difference between the direct equivalents (CRCW0805750RJNEA, ERJ-6GEYJ751V, RMCF0805JT750R)?

A: All three parts share identical electrical specifications: 750 Ω ±5%, 0.125W, 0805 package, ±200ppm/°C temperature coefficient, and AEC-Q200 rating. Differences are limited to manufacturer, packaging format (Tape & Reel), and physical height tolerances (0.020" to 0.028" seated height). Selection depends on supplier availability and specific PCB assembly requirements.

Q: Is CRCW0805750RFKEA compatible with the original MCR10EZPJ751 design?

A: Yes, with enhanced specifications. CRCW0805750RFKEA maintains the same 750 Ω resistance, 0.125W power rating, 0805 package, and AEC-Q200 certification. The upgrade features ±1% tolerance (vs. ±5%) and ±100ppm/°C temperature coefficient (vs. ±200ppm/°C), providing superior accuracy and stability for precision applications.

Q: Can CR0805-JW-751ELF replace MCR10EZPJ751 in automotive applications?

A: No. While CR0805-JW-751ELF matches the electrical specifications (750 Ω ±5%, 0.125W, 0805 package), it lacks AEC-Q200 automotive certification. Use only in non-automotive applications where automotive qualification is not required.

Q: What packaging formats are available for these substitutes?

A: Direct equivalents are supplied in Tape & Reel (TR) format. CRCW0805750RFKEA is available in Cut Tape (CT) & Digi-Reel® format. All parts maintain identical 0805 (2012 Metric) package dimensions and are compatible with standard SMD assembly processes.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental compliance of the original MCR10EZPJ751.
