MCR03EZPFX1370 Equivalent & Substitute Parts
Part Overview
The MCR03EZPFX1370 is a 137 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, necessitating identification of equivalent alternatives that maintain identical electrical and mechanical specifications for seamless circuit board integration.

Substitute Part Grouping Explanation
Substitution eligibility for the MCR03EZPFX1370 is determined by strict equivalence across the following parameters: resistance value (137 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, REACH Unaffected, EAR99).
Parts are classified into two categories:
Direct Substitutes maintain all electrical and mechanical specifications including automotive AEC-Q200 qualification: CRCW0603137RFKEA (Vishay Dale), ERJ-3EKF1370V (Panasonic Electronic Components), and RMCF0603FT137R (Stackpole Electronics Inc).
Similar Substitutes match all core electrical parameters and package specifications but differ in specific feature certifications: CR0603-FX-1370ELF (Bourns Inc., moisture resistant) and RC0603FR-07137RL (YAGEO, moisture resistant).

Engineering Selection Recommendations
For applications requiring automotive AEC-Q200 compliance, select from direct substitutes: CRCW0603137RFKEA (Vishay Dale, 1350 pcs available), ERJ-3EKF1370V (Panasonic Electronic Components, 231872 pcs available), or RMCF0603FT137R (Stackpole Electronics Inc, 5152 pcs available). All three maintain full specification equivalence with the discontinued MCR03EZPFX1370.
For non-automotive applications where AEC-Q200 certification is not required, CR0603-FX-1370ELF (Bourns Inc., 25709 pcs available) and RC0603FR-07137RL (YAGEO, 186592 pcs available) provide electrical and mechanical compatibility with moisture-resistant thick film construction.
Selection should prioritize product availability and supply chain continuity. ERJ-3EKF1370V offers the highest inventory level among direct substitutes.
Frequently Asked Questions (FAQ)
Q: Can I use CR0603-FX-1370ELF or RC0603FR-07137RL as direct replacements in automotive applications?
A: CR0603-FX-1370ELF and RC0603FR-07137RL lack automotive AEC-Q200 certification. Use these only in non-automotive circuits. For automotive applications, select CRCW0603137RFKEA, ERJ-3EKF1370V, or RMCF0603FT137R.
Q: Are all substitute parts physically compatible with the original PCB footprint?
A: All substitute parts use the 0603 (1608 Metric) package. Physical dimensions vary slightly within tolerance: length ranges from 0.061" to 0.063" (1.55mm to 1.60mm) and height from 0.020" to 0.022" (0.50mm to 0.55mm). These variations are within standard PCB design tolerances for 0603 components.
Q: What is the difference between direct and similar substitutes?
A: Direct substitutes (CRCW0603137RFKEA, ERJ-3EKF1370V, RMCF0603FT137R) maintain automotive AEC-Q200 qualification. Similar substitutes (CR0603-FX-1370ELF, RC0603FR-07137RL) match electrical specifications but feature moisture-resistant construction without automotive certification.
Q: Do all parts meet RoHS and REACH compliance?
A: All listed substitutes are ROHS3 compliant and REACH unaffected, matching the original MCR03EZPFX1370 compliance status.
Q: Which substitute offers the best supply availability?
A: ERJ-3EKF1370V (Panasonic Electronic Components) provides the highest inventory at 231872 pcs, followed by RC0603FR-07137RL (YAGEO) at 186592 pcs.
