MCR03EZPFX2433 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX2433 is a 243 kOhms ±1% 0.1W thick film chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This automotive-grade component meets AEC-Q200 qualification standards and operates across -55°C to 155°C. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active manufacturers to maintain design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Resistance value: 243 kOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Termination count: 2
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

Substitute parts are classified into two categories:

Direct Substitutes meet all electrical and mechanical parameters with identical or compatible packaging configurations. These parts are sourced from different manufacturers but maintain full functional equivalence.

Similar Substitutes meet all core electrical specifications and package dimensions but may differ in secondary features (such as moisture resistance designation) while maintaining operational compatibility within the specified parameter envelope.

Engineering Selection Recommendations

Direct Substitutes with AEC-Q200 Certification (Recommended for Automotive Applications):

• CRCW0603243KFKEA (Vishay Dale) — Active status, 28,805 units in stock, Tape & Reel packaging
• ERJ-3EKF2433V (Panasonic Electronic Components) — Active status, 56,078 units in stock, Tape & Reel packaging
• RMCF0603FG243K (Stackpole Electronics Inc) — Active status, 15,620 units in stock, Cut Tape packaging
• RMCF0603FT243K (Stackpole Electronics Inc) — Active status, 149,991 units in stock, Tape & Reel packaging

These parts maintain full AEC-Q200 automotive qualification matching the original MCR03EZPFX2433 specification.

Similar Substitutes (Non-Automotive Rated):

• CR0603-FX-2433ELF (Bourns Inc.) — Active status, 15,058 units in stock, moisture-resistant designation
• RC0603FR-07243KL (YAGEO) — Active status, 385,834 units in stock, moisture-resistant designation

These parts meet all electrical and mechanical parameters but lack explicit AEC-Q200 certification. Selection should be based on application requirements and automotive qualification necessity.

Frequently Asked Questions (FAQ)

Q: Can MCR03ERTF2433 be used as a direct replacement for MCR03EZPFX2433?

A: MCR03ERTF2433 shares identical electrical specifications (243 kOhms, ±1%, 0.1W, 0603 package, ±100ppm/°C, -55°C ~ 155°C) and is also discontinued. Both are Rohm Semiconductor products from the MCR series. The primary difference is packaging format (Cut Tape/Digi-Reel versus unspecified). Functional equivalence is confirmed; however, active alternatives from other manufacturers are recommended for new supply chain sourcing.

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

A: Direct substitutes (CRCW0603243KFKEA, ERJ-3EKF2433V, RMCF0603FG243K, RMCF0603FT243K) maintain AEC-Q200 automotive certification identical to the original part. Similar substitutes (CR0603-FX-2433ELF, RC0603FR-07243KL) meet all electrical and dimensional specifications but are designated as moisture-resistant without explicit automotive qualification. Selection depends on whether AEC-Q200 compliance is a design requirement.

Q: Are there packaging considerations when selecting a substitute?

A: Yes. Substitutes are available in two packaging formats: Cut Tape (CT) and Tape & Reel (TR). Cut Tape packaging is suitable for small-volume or prototype applications. Tape & Reel packaging is standard for high-volume production. Verify your assembly process requirements and procurement volume before selecting between RMCF0603FG243K (Cut Tape) and RMCF0603FT243K (Tape & Reel), both from Stackpole Electronics Inc.

Q: Can I use RC0603FR-07243KL or CR0603-FX-2433ELF in automotive applications?

A: RC0603FR-07243KL and CR0603-FX-2433ELF meet all electrical specifications (243 kOhms, ±1%, 0.1W, 0603, ±100ppm/°C, -55°C ~ 155°C) and are RoHS3 compliant. However, they lack AEC-Q200 automotive certification. Use in automotive applications only if your design does not mandate AEC-Q200 qualification or if equivalent qualification has been independently verified through your quality assurance process.

Q: What inventory levels should I consider?

A: YAGEO RC0603FR-07243KL offers the highest inventory (385,834 units), followed by Stackpole RMCF0603FT243K (149,991 units) and Panasonic ERJ-3EKF2433V (56,078 units). Inventory levels support long-term supply chain planning and reduce procurement risk for high-volume applications.
