Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX27R4 is determined by strict equivalence across the following parameters:

• Resistance value: 27.4 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 to 155°C
• Termination count: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All identified substitute parts meet these core electrical and mechanical specifications. Substitutes are categorized as Direct (full automotive AEC-Q200 rating) or Similar (moisture-resistant alternatives without explicit automotive certification).

Parameter Comparison

Engineering Selection Recommendations

For applications requiring automotive AEC-Q200 certification, direct substitutes are:

• CRCW060327R4FKEA (Vishay Dale) - Active status, 8524 units in stock
• ERJ-3EKF27R4V (Panasonic Electronic Components) - Active status, 88560 units in stock
• RMCF0603FT27R4 (Stackpole Electronics Inc) - Active status, 10570 units in stock

For applications where AEC-Q200 certification is not mandatory, moisture-resistant alternatives are available:

• CR0603-FX-27R4ELF (Bourns Inc.) - Active status, 63693 units in stock
• RC0603FR-0727R4L (YAGEO) - Active status, 184712 units in stock

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical electrical specifications. Selection should prioritize active-status components with adequate inventory availability for production requirements.

Frequently Asked Questions (FAQ)

Q: Can CR0603-FX-27R4ELF or RC0603FR-0727R4L be used in place of MCR03EZPFX27R4 in automotive applications?

A: These parts are electrically and mechanically equivalent but lack explicit AEC-Q200 automotive certification. They are suitable for non-automotive applications or where automotive certification is not a design requirement. For certified automotive use, select CRCW060327R4FKEA, ERJ-3EKF27R4V, or RMCF0603FT27R4.

Q: Are all substitute parts in the same 0603 package?

A: Yes. All substitute parts use the 0603 (1608 Metric) package with identical termination count (2) and compatible physical dimensions for PCB footprint compatibility.

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

A: Direct substitutes (CRCW060327R4FKEA, ERJ-3EKF27R4V, RMCF0603FT27R4) carry AEC-Q200 automotive rating matching the original part. Similar substitutes (CR0603-FX-27R4ELF, RC0603FR-0727R4L) meet all electrical and mechanical specifications but feature moisture-resistant composition without automotive certification.

Q: Do all substitutes have the same temperature coefficient?

A: Yes. All substitute parts maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating range, ensuring thermal performance equivalence.

Q: Which substitute has the highest inventory availability?

A: RC0603FR-0727R4L (YAGEO) has 184712 units in stock, followed by ERJ-3EKF27R4V (Panasonic) with 88560 units.
