Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX30R9 is determined by strict equivalence across the following critical parameters:

• Resistance value: 30.9 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. Differences in physical dimensions (length and height) within the 0603 package tolerance, packaging format (Cut Tape vs. Tape & Reel), and optional automotive certifications do not affect functional equivalence for direct replacement applications.

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification, select from CRCW060330R9FKEA (Vishay Dale), ERJ-3EKF30R9V (Panasonic), or RMCF0603FT30R9 (Stackpole Electronics). All three are currently active in production with full automotive certification.

For non-automotive applications or where automotive certification is not mandatory, RC0603FR-0730R9L (YAGEO) offers the highest inventory availability (175,813 pcs) and active product status. MCR03ERTF30R9 (Rohm Semiconductor) is electrically equivalent but lacks AEC-Q200 certification and is discontinued.

All substitute parts are ROHS3 compliant with MSL 1 rating, ensuring compatibility with standard PCB assembly processes and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can MCR03ERTF30R9 replace MCR03EZPFX30R9 in automotive applications?

A: MCR03ERTF30R9 meets all electrical and mechanical specifications but lacks AEC-Q200 automotive certification. Use only in non-automotive applications or where automotive qualification is not required.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Both packaging formats contain identical components. Cut Tape (CT) is suitable for smaller quantities and manual assembly, while Tape & Reel (TR) is optimized for automated pick-and-place equipment in high-volume production.

Q: Are physical dimension variations within the 0603 package critical?

A: Minor variations in length (0.061" to 0.063") and height (0.020" to 0.022") are within 0603 package tolerance and do not affect PCB footprint compatibility or functional performance.

Q: Which substitute offers the best availability?

A: RC0603FR-0730R9L (YAGEO) has the highest inventory level at 175,813 pcs with active product status.

Q: Do all substitutes have identical moisture sensitivity ratings?

A: Yes, all parts are rated MSL 1 (Unlimited), requiring no special moisture control during storage or assembly.
