Substitute Part Grouping Explanation

Substitute parts for the AF0201FR-0746K4L are qualified based on the following critical parameters:

• Resistance value: 46.4 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Package format: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The identified substitute parts meet all these criteria and are therefore electrically and mechanically interchangeable with the primary part number.

Parameter Comparison

Engineering Selection Recommendations

All three parts—AF0201FR-0746K4L (YAGEO), CRCW020146K4FNED (Vishay Dale), and ERJ-1GNF4642C (Panasonic)—are active production components with ROHS3 compliance and MSL 1 moisture sensitivity ratings. The CRCW020146K4FNED offers an extended operating temperature range of -55°C ~ 155°C compared to the standard -55°C ~ 125°C range of the primary and Panasonic parts. Selection should be based on availability, lead time, and specific thermal requirements of the application. All parts are suitable for automotive and industrial applications requiring AEC-Q200 or equivalent reliability standards.

Frequently Asked Questions (FAQ)

Q: Can CRCW020146K4FNED be used as a direct replacement for AF0201FR-0746K4L?

A: Yes. Both parts share identical electrical specifications (46.4 kOhms, ±1%, 0.05W) and physical dimensions (0201 package). The CRCW020146K4FNED has a higher maximum operating temperature (155°C vs. 125°C), making it suitable for applications requiring extended thermal performance.

Q: Are there any package compatibility issues between these substitute parts?

A: No. All three parts use the 0201 (0603 Metric) package with identical physical dimensions (0.024" L x 0.012" W, 0.60mm x 0.30mm) and maximum seated height (0.010" / 0.26mm). They are footprint-compatible for PCB assembly.

Q: What is the significance of the anti-sulfur coating on the AF0201FR-0746K4L?

A: The anti-sulfur feature on the YAGEO part provides protection against sulfur-containing environmental contaminants. The Vishay Dale and Panasonic substitutes do not list this specific feature in their specifications, which may be a consideration for applications in corrosive environments.

Q: Do all substitute parts meet automotive qualification standards?

A: The AF0201FR-0746K4L carries AEC-Q200 automotive qualification. The CRCW020146K4FNED and ERJ-1GNF4642C do not list specific automotive ratings in the provided specifications, though both manufacturers produce automotive-grade components.

Q: What is the difference in inventory availability?

A: AF0201FR-0746K4L has 804 units in stock, CRCW020146K4FNED has 28,383 units, and ERJ-1GNF4642C has 56,285 units available. Higher inventory levels may indicate better lead time availability for high-volume production requirements.
