MCR03EZPFX2550 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX2550 is a 255 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.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX2550 is determined by strict equivalence across the following parameters: resistance value (255 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, EAR99, HTSUS 8533.21.0030).

The substitute parts are grouped into two categories:

Direct Equivalents (CRCW0603255RFKEA, ERJ-3EKF2550V, RMCF0603FT255R): These parts meet all electrical and mechanical parameters identically to the MCR03EZPFX2550, including automotive AEC-Q200 qualification. Physical dimensions vary slightly within acceptable tolerances for 0603 package specifications.

Similar Equivalent (RC0603FR-07255RL): This YAGEO part matches all core electrical parameters and package specifications. It features moisture-resistant thick film composition instead of automotive AEC-Q200 rating, making it suitable for applications where automotive qualification is not required.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring automotive AEC-Q200 qualification, select from the direct equivalents: CRCW0603255RFKEA (Vishay Dale), ERJ-3EKF2550V (Panasonic Electronic Components), or RMCF0603FT255R (Stackpole Electronics Inc). All three maintain active product status with established supply availability.

For non-automotive applications where moisture resistance is the primary requirement, RC0603FR-07255RL (YAGEO) provides full electrical and mechanical compatibility with ROHS3 compliance and unlimited MSL rating.

All substitute parts comply with ECCN EAR99 and HTSUS 8533.21.0030 classifications, matching the original part's regulatory framework.

Frequently Asked Questions (FAQ)

Q: Can CRCW0603255RFKEA replace MCR03EZPFX2550 in automotive applications? A: Yes. CRCW0603255RFKEA meets all electrical parameters (255 Ohms ±1%, 0.1W, ±100ppm/°C, -55°C to 155°C) and carries AEC-Q200 automotive qualification identical to the original part. Physical dimensions are within 0603 package tolerance specifications.

Q: What is the difference between the direct equivalents and RC0603FR-07255RL? A: The direct equivalents (Vishay Dale, Panasonic, Stackpole) carry AEC-Q200 automotive qualification. RC0603FR-07255RL features moisture-resistant composition without automotive qualification. Select based on application requirements.

Q: Are all substitutes available in the same packaging format? A: CRCW0603255RFKEA, ERJ-3EKF2550V, and RMCF0603FT255R are supplied in Tape & Reel (TR) format. RC0603FR-07255RL is available in Cut Tape (CT) & Digi-Reel format. Verify packaging compatibility with assembly equipment specifications.

Q: Do all substitutes have the same moisture sensitivity level? A: Yes. All substitute parts carry MSL 1 (Unlimited) rating, matching the original MCR03EZPFX2550 specification.

Q: Which substitute has the highest inventory availability? A: RMCF0603FT255R (Stackpole Electronics Inc) has 188,156 pieces in stock, followed by ERJ-3EKF2550V (Panasonic) with 84,451 pieces.
