MCR03EZPFX2203 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX2203 is a 220 kOhms ±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 direct board-level substitution.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (220 kOhms), 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). All identified substitutes maintain these core specifications. Parts are grouped by substitution category based on product status and availability: upgrade options (active status with enhanced features), direct equivalents (active status with identical specifications), and similar alternatives (active status with minor feature variations or non-automotive ratings).

Engineering Selection Recommendations

For applications requiring strict automotive AEC-Q200 compliance, select from the following active parts: KTR03EZPF2203 (Rohm Semiconductor upgrade option with high voltage features), CRCW0603220KFKEA (Vishay Dale, highest inventory availability), ERJ-3EKF2203V (Panasonic, high inventory), RMCF0603FG220K, or RMCF0603FT220K (Stackpole Electronics, with RMCF0603FT220K offering maximum inventory depth). All five parts maintain full AEC-Q200 qualification and ROHS3 compliance identical to the original MCR03EZPFX2203.

For non-automotive applications where AEC-Q200 certification is not required, CRG0603F220K (TE Connectivity) and RC0603FR-07220KL (YAGEO) provide electrically equivalent alternatives with active product status and adequate inventory levels.

Frequently Asked Questions (FAQ)

Q: Can KTR03EZPF2203 directly replace MCR03EZPFX2203 on automotive boards?

A: Yes. KTR03EZPF2203 is manufactured by the same supplier (Rohm Semiconductor) and maintains identical electrical specifications (220 kOhms ±1%, 0.1W, ±100ppm/°C) and AEC-Q200 automotive qualification. The KTR series represents an active product line upgrade with high voltage features, making it a direct functional substitute.

Q: What is the difference between RMCF0603FG220K and RMCF0603FT220K?

A: Both parts are manufactured by Stackpole Electronics with identical electrical and mechanical specifications. The primary distinction is inventory availability: RMCF0603FT220K has significantly higher stock (2,007,586 pcs vs. 10,191 pcs). Both maintain AEC-Q200 qualification and are suitable for automotive applications.

Q: Are CRG0603F220K and RC0603FR-07220KL suitable for automotive applications?

A: These parts meet all electrical and mechanical specifications of the original MCR03EZPFX2203 but lack AEC-Q200 automotive certification. They are suitable for non-automotive or non-safety-critical applications. For automotive designs requiring AEC-Q200 compliance, use alternatives from the AEC-Q200 qualified group.

Q: How do physical dimensions affect substitution?

A: All substitute parts use the 0603 (1608 Metric) package with compatible footprints. Minor dimensional variations (length 1.55mm to 1.60mm, width 0.80mm to 0.85mm, height 0.50mm to 0.55mm) fall within standard PCB design tolerances and do not affect board-level substitution.

Q: What packaging options are available?

A: KTR03EZPF2203 is supplied in Tape & Reel (TR) packaging. CRCW0603220KFKEA, RMCF0603FG220K, RMCF0603FT220K, and CRG0603F220K are supplied in Tape & Reel (TR). ERJ-3EKF2203V and RC0603FR-07220KL are supplied in Cut Tape (CT) & Digi-Reel® format. Packaging selection depends on assembly process requirements.
