MCR03EZPFX2400 Equivalent & Substitute Parts
Part Overview
The MCR03EZPFX2400 is a 240 Ohms ±1% 0.1W chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This thick film resistor meets automotive AEC-Q200 qualification standards and operates across -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 eligibility is determined by strict equivalence across the following parameters: resistance value (240 Ohms), 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 compliance certifications (ROHS3, MSL 1).
The substitute parts are grouped into three categories:
Upgrade Option: KTR03EZPF2400 (Rohm Semiconductor) — Active product with identical electrical specifications and added high-voltage capability.
Direct Equivalents: CRCW0603240RFKEA (Vishay Dale), ERJ-3EKF2400V (Panasonic), RMCF0603FG240R (Stackpole), and RMCF0603FT240R (Stackpole) — All meet or exceed the original specifications with active product status.
Similar Alternatives: CR0603-FX-2400ELF (Bourns) and RC0603FR-07240RL (YAGEO) — Meet core electrical and mechanical specifications with moisture-resistant features but lack automotive AEC-Q200 certification.

Engineering Selection Recommendations
For applications requiring automotive AEC-Q200 compliance, select from the direct equivalents: CRCW0603240RFKEA, ERJ-3EKF2400V, RMCF0603FG240R, or RMCF0603FT240R. All maintain identical electrical specifications and certifications as the original MCR03EZPFX2400.
KTR03EZPF2400 from Rohm Semiconductor provides an upgrade path with high-voltage capability while maintaining all original specifications and AEC-Q200 qualification.
CR0603-FX-2400ELF and RC0603FR-07240RL are suitable only for non-automotive applications where AEC-Q200 certification is not required. Both parts meet the core electrical and mechanical specifications with moisture-resistant construction.
All substitute parts are ROHS3 compliant with MSL 1 rating and identical operating temperature ranges.
Frequently Asked Questions (FAQ)
Q: Can I use CR0603-FX-2400ELF or RC0603FR-07240RL as direct replacements in automotive applications?
A: No. These parts lack AEC-Q200 automotive qualification. Use only CRCW0603240RFKEA, ERJ-3EKF2400V, RMCF0603FG240R, RMCF0603FT240R, or KTR03EZPF2400 for automotive applications.
Q: Are all substitute parts compatible with the original 0603 package footprint?
A: Yes. All listed substitutes use the 0603 (1608 Metric) package with identical termination count (2) and compatible mechanical dimensions within standard PCB assembly tolerances.
Q: What is the difference between RMCF0603FG240R and RMCF0603FT240R?
A: Both are Stackpole RMCF series 240 Ohm ±1% 0.1W 0603 resistors with identical electrical specifications, AEC-Q200 compliance, and operating parameters. Selection between them depends on packaging preference and inventory availability.
Q: Is KTR03EZPF2400 a superior choice to other substitutes?
A: KTR03EZPF2400 offers high-voltage capability in addition to standard specifications. For applications not requiring high-voltage features, all AEC-Q200 qualified substitutes are functionally equivalent.
Q: Do all parts meet ROHS3 compliance?
A: Yes. All listed parts are ROHS3 compliant with MSL 1 moisture sensitivity rating and REACH unaffected status.
