Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX28R7 is determined by strict equivalence across the following critical parameters:

• Resistance value: 28.7 Ohms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package type: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All substitute parts listed meet these electrical and mechanical specifications. The CRCW060328R7FKEA, ERJ-3EKF28R7V, and RMCF0603FT28R7 are direct equivalents with active product status. The RC0603FR-0728R7L is classified as a similar substitute with moisture-resistant features instead of automotive AEC-Q200 rating.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement of the discontinued MCR03EZPFX28R7, the CRCW060328R7FKEA (Vishay Dale), ERJ-3EKF28R7V (Panasonic), and RMCF0603FT28R7 (Stackpole) are preferred selections. All three maintain active product status, AEC-Q200 automotive certification, and identical electrical specifications. These parts are suitable for automotive and industrial applications requiring AEC-Q200 compliance.

The RC0603FR-0728R7L (YAGEO) is a functional equivalent with moisture-resistant features. This part meets all core electrical and mechanical parameters but carries moisture-resistant designation rather than automotive AEC-Q200 rating. Selection of this part should be based on application requirements and compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can CRCW060328R7FKEA replace MCR03EZPFX28R7 in automotive applications? A: Yes. Both parts share identical electrical specifications (28.7 Ohms ±1%, 0.1W), package type (0603), and AEC-Q200 automotive certification. CRCW060328R7FKEA is actively manufactured and available in higher inventory quantities.

Q: What is the difference between the direct equivalents and RC0603FR-0728R7L? A: The CRCW060328R7FKEA, ERJ-3EKF28R7V, and RMCF0603FT28R7 carry AEC-Q200 automotive rating. The RC0603FR-0728R7L is rated for moisture resistance instead. All meet identical electrical and thermal specifications. Selection depends on whether automotive certification is required for your application.

Q: Are there physical dimension differences between these parts? A: Minor variations exist within tolerance. The CRCW060328R7FKEA and RMCF0603FT28R7 measure 0.061" L × 0.031" W and 0.061" L × 0.031" W respectively, while MCR03EZPFX28R7 and ERJ-3EKF28R7V measure 0.063" L × 0.031" W. All fit the 0603 (1608 Metric) package footprint. Height differences range from 0.020" to 0.022" maximum seated height, all within standard PCB assembly tolerances.

Q: Do all substitutes have the same moisture sensitivity level? A: Yes. All listed parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Which substitute has the highest inventory availability? A: ERJ-3EKF28R7V (Panasonic) has 143,378 pieces in stock, followed by RC0603FR-0728R7L (YAGEO) with 20,016 pieces, CRCW060328R7FKEA (Vishay Dale) with 29,150 pieces, and RMCF0603FT28R7 (Stackpole) with 1,457 pieces.
