MCR03EZPFX2051 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX2051 is a 2.05 kOhms ±1% 0.1W chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This thick film resistor is designed for automotive applications with AEC-Q200 qualification and operates across -55°C to 155°C. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active manufacturers to maintain design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX2051 is determined by strict equivalence across the following parameters:

• Resistance value: 2.05 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.1W / 1/10W (exact match required)
• Package: 0603 (1608 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Termination count: 2 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• MSL rating: 1 (Unlimited) (exact match required)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the MCR03EZPFX2051 in PCB assembly applications.

Parameter Comparison

Engineering Selection Recommendations

Five substitute parts are currently available from active manufacturers: CRCW06032K05FKEA (Vishay Dale), ERJ-3EKF2051V (Panasonic), RMCF0603FT2K05 (Stackpole Electronics), CR0603-FX-2051ELF (Bourns), and RC0603FR-072K05L (YAGEO). All meet the electrical and mechanical specifications of the MCR03EZPFX2051 and carry ROHS3 compliance with AEC-Q200 automotive qualification (where specified by manufacturer).

For automotive applications requiring AEC-Q200 certification, CRCW06032K05FKEA, ERJ-3EKF2051V, and RMCF0603FT2K05 are qualified options. CR0603-FX-2051ELF and RC0603FR-072K05L provide moisture-resistant thick film construction suitable for general industrial applications. Selection should be based on supply availability, lead time, and specific application requirements within the defined parameter set.

Frequently Asked Questions (FAQ)

Q: Can MCR03EZPFX2051 be directly replaced with any of the listed substitutes?

A: Yes. All listed substitute parts are electrically and mechanically equivalent, meeting identical specifications for resistance, tolerance, power rating, package dimensions, temperature range, and compliance certifications. Direct PCB substitution is permissible without circuit redesign.

Q: What is the difference between the MCR03EZPFX2051 and TRR03EZPF2051?

A: Both are Rohm Semiconductor products with identical electrical specifications. The primary difference is packaging: MCR03EZPFX2051 is supplied in bulk, while TRR03EZPF2051 is supplied in Tape & Reel format. TRR03EZPF2051 is marked as obsolete.

Q: Are all substitute parts suitable for automotive applications?

A: CRCW06032K05FKEA, ERJ-3EKF2051V, and RMCF0603FT2K05 carry AEC-Q200 automotive qualification. CR0603-FX-2051ELF and RC0603FR-072K05L are rated for general industrial use with moisture-resistant properties. Application requirements should determine selection.

Q: Do all substitutes have the same physical dimensions?

A: All parts conform to the 0603 (1608 Metric) package standard. Minor dimensional variations exist within tolerance: length ranges from 0.061" to 0.063" (1.55mm to 1.60mm), width from 0.031" to 0.033" (0.80mm to 0.85mm), and height from 0.020" to 0.022" (0.50mm to 0.55mm). These variations are within standard PCB design tolerances and do not affect interchangeability.

Q: What is the inventory status of substitute parts?

A: RMCF0603FT2K05 (108,298 pcs), CR0603-FX-2051ELF (65,716 pcs), and ERJ-3EKF2051V (54,140 pcs) have substantial inventory. RC0603FR-072K05L (20,100 pcs) and CRCW06032K05FKEA (1,500 pcs) have lower availability. Inventory levels should be confirmed with suppliers for production planning.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and carry MSL rating of 1 (Unlimited), matching the MCR03EZPFX2051 environmental and regulatory specifications.
