MCR03EZPFX2431 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX2431 is a 2.43 kOhms ±1% 0.1W chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This thick film resistor meets automotive AEC-Q200 specifications with an operating temperature range of -55°C to 155°C. The part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain the same electrical and mechanical characteristics for continued design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MCR03EZPFX2431 are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 2.43 kOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package / Case: 0603 (1608 Metric)
• Number of terminations: 2
• Moisture Sensitivity Level: 1 (Unlimited)

Compliance Parameters (Must Match):

• RoHS3 Compliant
• REACH Unaffected

Substitute parts are grouped into two categories: Direct equivalents (identical electrical and mechanical specifications) and Similar equivalents (functionally equivalent with minor dimensional variations within tolerance). All listed substitutes maintain the same resistance value, tolerance, power rating, and operating temperature range, ensuring direct functional replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendations (Active Status with AEC-Q200):

CRCW06032K43FKEA (Vishay Dale), ERJ-3EKF2431V (Panasonic Electronic Components), and RMCF0603FT2K43 (Stackpole Electronics Inc) are the preferred substitutes. All three maintain active product status, automotive AEC-Q200 certification, and full compliance with ROHS3 and REACH requirements. These parts provide the highest availability and long-term supply assurance.

Secondary Recommendations (Active Status, Non-Automotive Certified):

CR0603-FX-2431ELF (Bourns Inc.) and RC0603FR-072K43L (YAGEO) are functionally equivalent alternatives with active product status. While these parts do not carry automotive AEC-Q200 certification, they meet all electrical and mechanical specifications and maintain ROHS3 compliance. These options are suitable for non-automotive applications or where automotive certification is not required.

Not Recommended:

TRR03EZPF2431 and CRCW06032K43FKEB are obsolete or discontinued, limiting long-term availability and supply continuity.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for MCR03EZPFX2431?

A: Yes. All listed substitute parts share identical electrical parameters (2.43 kOhms, ±1% tolerance, 0.1W power rating, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range) and the same 0603 package. They are mechanically and electrically interchangeable in circuit applications.

Q: What is the difference between parts with "Automotive AEC-Q200" and those without?

A: Automotive AEC-Q200 certification indicates the part meets automotive industry reliability and quality standards. Parts with this certification are qualified for automotive applications. Parts without this designation are suitable for general industrial and consumer applications but may not meet automotive qualification requirements.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within manufacturing tolerance. The MCR03EZPFX2431 specifies 0.063" L x 0.031" W (1.60mm x 0.80mm) with 0.022" (0.55mm) maximum seated height. Substitute parts from Vishay Dale (CRCW series) specify 0.061" L x 0.033" W (1.55mm x 0.85mm) with 0.020" (0.50mm) maximum seated height, and Stackpole (RMCF series) specifies 0.061" L x 0.031" W (1.55mm x 0.80mm) with 0.022" (0.55mm) maximum seated height. All variations remain within 0603 package specifications and do not affect PCB layout or assembly compatibility.

Q: Which substitute offers the best long-term availability?

A: RMCF0603FT2K43 (Stackpole Electronics Inc) currently shows the highest inventory level (179,958 pcs) with active product status, providing strong supply continuity. CRCW06032K43FKEA (Vishay Dale) and ERJ-3EKF2431V (Panasonic Electronic Components) also maintain active status with substantial inventory levels.

Q: Do all substitutes meet RoHS and REACH compliance?

A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, matching the compliance profile of the original MCR03EZPFX2431.
