MCR03EZPFX1600 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX1600 is a 160 Ohms ±1% 0.1W chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This thick film resistor meets Automotive AEC-Q200 qualification 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 (160 Ohms), tolerance (±1%), power rating (0.1W), package type (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3, MSL 1).

Substitute parts are grouped into three categories:

Direct Substitutes (Automotive AEC-Q200): Parts meeting all electrical specifications and automotive qualification. These are functionally interchangeable with the MCR03EZPFX1600 in automotive applications.

Upgrade Substitute (Active Status): KTR03EZPF1600 from Rohm Semiconductor offers the same electrical specifications with active product status and high voltage capability, providing supply continuity.

Similar Substitutes (Non-Automotive Features): CR0603-FX-1600ELF and RC0603FR-07160RL meet all core electrical parameters but feature moisture resistance instead of automotive qualification. These are suitable for non-automotive applications with equivalent electrical performance.

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 compliance, select from CRCW0603160RFKEA (Vishay Dale), ERJ-3EKF1600V (Panasonic), or RMCF0603FT160R (Stackpole). All three are active products with full automotive qualification and high inventory availability. RMCF0603FT160R offers the largest inventory (305,332 pcs), ensuring supply continuity.

For Rohm Semiconductor continuity within the same manufacturer ecosystem, KTR03EZPF1600 provides active status with AEC-Q200 qualification and high voltage capability, replacing the discontinued MCR03EZPFX1600.

For non-automotive applications where AEC-Q200 is not required, CR0603-FX-1600ELF (Bourns) and RC0603FR-07160RL (YAGEO) are suitable alternatives with active product status and moisture-resistant thick film construction.

Frequently Asked Questions (FAQ)

Q: Can MCR03ERTF1600 directly replace MCR03EZPFX1600?

A: MCR03ERTF1600 matches all electrical specifications (160 Ω, ±1%, 0.1W, 0603 package, ±100ppm/°C, -55°C ~ 155°C). However, MCR03ERTF1600 lacks AEC-Q200 automotive qualification present in the original part. Use only in non-automotive applications or where automotive certification is not required.

Q: What is the difference between direct substitutes and similar substitutes?

A: Direct substitutes (CRCW0603160RFKEA, ERJ-3EKF1600V, RMCF0603FT160R) maintain AEC-Q200 automotive qualification matching the original MCR03EZPFX1600. Similar substitutes (CR0603-FX-1600ELF, RC0603FR-07160RL) meet all electrical parameters but feature moisture resistance instead of automotive certification, suitable for non-automotive designs.

Q: Are all substitutes pin-compatible with the original part?

A: Yes. All listed substitutes use the 0603 (1608 Metric) package with 2 terminations, ensuring mechanical and electrical compatibility on PCBs designed for the MCR03EZPFX1600.

Q: Which substitute offers the best supply availability?

A: RMCF0603FT160R (Stackpole) provides the highest inventory at 305,332 pcs with active product status and full AEC-Q200 compliance, making it the most reliable choice for sustained production requirements.

Q: Can I use CR0603-FX-1600ELF or RC0603FR-07160RL in automotive applications?

A: These parts lack AEC-Q200 automotive qualification. Use only in non-automotive applications. For automotive designs, select from CRCW0603160RFKEA, ERJ-3EKF1600V, RMCF0603FT160R, or KTR03EZPF1600.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling, simplifying logistics and inventory management across all listed parts.
