MCR03EZPFX1603 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX1603 is a 160 kOhms ±1% 0.1W chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This automotive-grade thick film resistor meets AEC-Q200 qualification and operates across -55°C to 155°C. The part is discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components that maintain electrical and mechanical compatibility for ongoing production and repair applications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (160 kOhms), tolerance (±1%), power rating (0.1W), package type (0603 / 1608 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), RoHS compliance (ROHS3), and moisture sensitivity level (MSL 1). Parts are categorized as direct substitutes when all parameters match exactly. Upgrade substitutes offer additional certifications (such as high voltage capability) while maintaining core electrical specifications. Similar substitutes meet all critical electrical and mechanical parameters but may lack automotive AEC-Q200 certification or feature moisture-resistant construction instead.

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification, select from KTR03EZPF1603 (Rohm, active status with high voltage capability), CRCW0603160KFKEA (Vishay Dale, active status with highest inventory), ERJ-3EKF1603V (Panasonic, active status with largest inventory), RMCF0603FG160K, or RMCF0603FT160K (Stackpole, both active status). These parts maintain full electrical equivalence and automotive compliance.

For non-automotive applications where AEC-Q200 certification is not required, CR0603-FX-1603ELF (Bourns), RC0603FR-07160KL (YAGEO), and RC1608F164CS (Samsung) provide active-status alternatives with moisture-resistant thick film construction. All listed substitutes are ROHS3 compliant with MSL 1 rating.

MCR03ERTF1603 (Rohm) is electrically equivalent but lacks AEC-Q200 certification and is discontinued, making it unsuitable for new designs despite current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can MCR03EZPFX1603 be replaced with any of the listed substitutes? A: Yes, all listed parts are mechanically and electrically compatible. Selection depends on application requirements. For automotive applications, use only AEC-Q200 qualified parts (KTR03EZPF1603, CRCW0603160KFKEA, ERJ-3EKF1603V, RMCF0603FG160K, RMCF0603FT160K). For general-purpose applications, non-automotive alternatives are acceptable.

Q: What is the difference between direct substitutes and similar substitutes? A: Direct substitutes match all electrical and mechanical parameters including automotive AEC-Q200 certification. Similar substitutes meet all critical electrical specifications (resistance, tolerance, power, package, temperature range) but lack AEC-Q200 rating or feature moisture-resistant construction instead of automotive-grade thick film.

Q: Are there dimensional differences between substitute parts? A: All parts use 0603 (1608 Metric) package. Minor dimensional variations exist: CRCW0603160KFKEA measures 0.061" L x 0.033" W (1.55mm x 0.85mm) with 0.020" max height; most others measure 0.063" L x 0.031" W (1.60mm x 0.80mm) with 0.022" max height. These variations are within standard PCB design tolerances and do not affect interchangeability.

Q: Which substitute offers the best availability? A: ERJ-3EKF1603V (Panasonic) has the highest inventory at 212,553 pieces, followed by RMCF0603FT160K (Stackpole) at 74,437 pieces and RC0603FR-07160KL (YAGEO) at 79,031 pieces.

Q: Is KTR03EZPF1603 an upgrade from MCR03EZPFX1603? A: KTR03EZPF1603 maintains electrical equivalence while adding high voltage capability and active product status. It is functionally compatible and recommended for new designs requiring Rohm components.

Q: Do all substitutes have the same moisture sensitivity level? A: Yes, all listed parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
