Key Parameters

Substitute Part Grouping Explanation

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

• Resistance value: 147 kOhms
• 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
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All identified substitute parts meet these core electrical and mechanical requirements. Parts are categorized as Direct Manufacturer equivalents (CRCW0603147KFKEA, ERJ-3EKF1473V, RMCF0603FT147K) or Similar alternatives (CR0603-FX-1473ELF, RC0603FR-07147KL) based on feature alignment and product status.

Parameter Comparison

Engineering Selection Recommendations

Direct Manufacturer equivalents (CRCW0603147KFKEA, ERJ-3EKF1473V, RMCF0603FT147K) provide full electrical and mechanical compatibility with the original MCR03EZPFX1473. All three maintain AEC-Q200 automotive qualification, ROHS3 compliance, and identical parameter specifications. RMCF0603FT147K from Stackpole Electronics offers the highest inventory availability (295,737 pcs), while ERJ-3EKF1473V from Panasonic provides 88,846 pcs in stock. CRCW0603147KFKEA from Vishay Dale maintains 43,257 pcs availability.

Similar alternatives (CR0603-FX-1473ELF from Bourns and RC0603FR-07147KL from YAGEO) meet all core electrical specifications and RoHS compliance requirements. CR0603-FX-1473ELF features moisture-resistant construction with 10,892 pcs available. RC0603FR-07147KL from YAGEO offers the largest inventory at 178,601 pcs and is available in Cut Tape (CT) & Digi-Reel® packaging. These alternatives lack explicit AEC-Q200 automotive certification but maintain equivalent electrical performance and environmental ratings.

Frequently Asked Questions (FAQ)

Q: Can RMCF0603FT147K directly replace MCR03EZPFX1473 in automotive applications?

A: Yes. RMCF0603FT147K meets all electrical specifications (147 kOhms ±1%, 0.1W, ±100ppm/°C) and maintains AEC-Q200 automotive qualification with identical operating temperature range (-55°C to 155°C). Physical dimensions and package footprint are compatible with 0603 (1608 Metric) PCB layouts.

Q: What is the difference between Direct Manufacturer equivalents and Similar alternatives?

A: Direct Manufacturer equivalents (CRCW0603147KFKEA, ERJ-3EKF1473V, RMCF0603FT147K) carry explicit AEC-Q200 automotive certification matching the original part. Similar alternatives (CR0603-FX-1473ELF, RC0603FR-07147KL) meet all electrical and environmental specifications but feature moisture-resistant construction instead of automotive-specific qualification.
