MCR03EZPFX2740 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX2740 is a 274 Ohms ±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 MCR03EZPFX2740 is determined by strict equivalence across the following parameters: resistance value (274 Ohms), tolerance (±1%), power rating (0.1W), package type (0603), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). All substitute parts listed maintain these core electrical and mechanical specifications, ensuring functional interchangeability in circuit applications.

Substitute parts are grouped into two categories based on automotive qualification status:

Direct Substitutes (Automotive AEC-Q200 Rated): Parts meeting the same automotive qualification as the original component.

Similar Substitutes (Non-Automotive Rated): Parts meeting all electrical and mechanical specifications but without automotive AEC-Q200 certification.

Engineering Selection Recommendations

For applications requiring automotive AEC-Q200 compliance, select from the following active parts: CRCW0603274RFKEA (Vishay Dale), ERJ-3EKF2740V (Panasonic Electronic Components), or RMCF0603FT274R (Stackpole Electronics Inc). All three maintain full electrical and mechanical equivalence to the original MCR03EZPFX2740 while offering active product status and established supply availability.

For non-automotive applications where AEC-Q200 certification is not required, CR0603-FX-2740ELF (Bourns Inc.) and RC0603FR-07274RL (YAGEO) provide functionally equivalent alternatives with active product status and higher inventory levels.

The MCR03ERTF2740 from Rohm Semiconductor offers direct manufacturer continuity but carries discontinued status, limiting its suitability for new designs.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical electrical performance specifications.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the MCR03EZPFX2740?

A: Yes, all listed substitute parts are electrically and mechanically equivalent. They share identical resistance (274 Ohms), tolerance (±1%), power rating (0.1W), package type (0603), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). Physical dimensions and termination count are also equivalent, enabling direct PCB placement without design modification.

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

A: Direct substitutes (CRCW0603274RFKEA, ERJ-3EKF2740V, RMCF0603FT274R) carry AEC-Q200 automotive qualification matching the original part. Similar substitutes (CR0603-FX-2740ELF, RC0603FR-07274RL) meet all electrical and mechanical specifications but lack automotive certification. Selection depends on application requirements and industry standards compliance.

Q: Why is the original MCR03EZPFX2740 discontinued?

A: The part is discontinued at DiGi Electronics. Substitute parts with active status provide continuity for production and maintenance applications.

Q: Are there any dimensional differences between substitute parts?

A: All parts use the 0603 (1608 Metric) package. Minor dimensional variations exist within standard tolerances: 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 remain within PCB design tolerances and do not affect interchangeability.

Q: Which substitute offers the highest inventory availability?

A: RC0603FR-07274RL (YAGEO) offers 654,297 pieces in stock, followed by RMCF0603FT274R (Stackpole Electronics Inc) with 331,450 pieces. Both provide substantial supply for production requirements.
