Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX20R0 is determined by strict equivalence across the following parameters:

• Resistance value: 20 Ohms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive compliance: AEC-Q200
• RoHS compliance: ROHS3
• Moisture sensitivity: MSL 1

All substitute parts listed meet these electrical and mechanical specifications. Dimensional variations within supplier tolerances do not affect functional equivalence. Parts are categorized as Direct Substitutes (functionally identical across all parameters) or Similar Substitutes (meeting all core parameters with additional features such as moisture resistance or anti-sulfur treatment).

Parameter Comparison

Engineering Selection Recommendations

For direct replacement of MCR03EZPFX20R0 in automotive applications requiring AEC-Q200 compliance, the following parts are recommended based on active product status and full specification alignment:

CRCW060320R0FKEA (Vishay Dale) is the primary substitute, offering identical electrical specifications with active product status and high inventory availability (75,198 pcs). ERJ-3EKF20R0V (Panasonic Electronic Components) and RMCF0603FT20R0 (Stackpole Electronics Inc) are alternative direct substitutes with active status and substantial stock levels.

For applications where AEC-Q200 certification is not mandatory, CR0603-FX-20R0ELF (Bourns Inc.), AC0603FR-0720RL (YAGEO), AF0603FR-0720RL (YAGEO), and RC0603FR-0720RL (YAGEO) provide equivalent electrical performance with additional features such as moisture resistance or anti-sulfur treatment. These parts maintain full RoHS3 compliance and identical thermal characteristics.

CRCW060320R0FKEB (Vishay Dale) meets all specifications but carries discontinued status, limiting its suitability for new production designs despite current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can CRCW060320R0FKEA directly replace MCR03EZPFX20R0 in automotive circuits?

A: Yes. CRCW060320R0FKEA meets all electrical and mechanical specifications of MCR03EZPFX20R0, including 20 Ohms ±1% resistance, 0.1W power rating, 0603 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, and AEC-Q200 automotive certification. The parts are functionally equivalent.

Q: What is the difference between Direct Substitutes and Similar Substitutes?

A: Direct Substitutes (CRCW060320R0FKEA, ERJ-3EKF20R0V, RMCF0603FT20R0) match all core electrical and mechanical parameters including AEC-Q200 rating. Similar Substitutes (AC0603FR-0720RL, AF0603FR-0720RL, CR0603-FX-20R0ELF, RC0603FR-0720RL) meet all electrical specifications but may lack AEC-Q200 certification or include additional features such as moisture resistance or anti-sulfur treatment.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within supplier tolerances. 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 do not affect functional equivalence or PCB assembly compatibility for 0603 package footprints.

Q: Which substitute offers the best inventory availability?

A: RMCF0603FT20R0 (Stackpole Electronics Inc) provides the highest inventory level at 254,546 pcs. CRCW060320R0FKEA (Vishay Dale) offers 75,198 pcs, and RC0603FR-0720RL (YAGEO) provides 95,621 pcs. All three maintain active product status.

Q: Can I use CR0603-FX-20R0ELF or RC0603FR-0720RL if AEC-Q200 is not required?

A: Yes. Both parts meet all electrical specifications (20 Ohms ±1%, 0.1W, 0603 package, ±100ppm/°C, -55°C to 155°C) and maintain RoHS3 compliance. CR0603-FX-20R0ELF includes moisture resistance; RC0603FR-0720RL includes moisture resistance. Selection depends on application requirements and packaging preference (Tape & Reel vs. Cut Tape).

Q: What is the significance of Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. All listed parts carry MSL 1 rating, eliminating moisture-related handling constraints during storage and assembly.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 Compliant status, meeting EU Restriction of Hazardous Substances requirements.
