Substitute Part Grouping Explanation

Substitute parts for the AF0201FR-074K3L are qualified based on the following criteria:

• Identical resistance value: 4.3 kOhms
• Matching tolerance: ±1%
• Equivalent power rating: 0.05W (1/20W)
• Identical package format: 0201 (0603 Metric)
• Matching composition: Thick Film
• Temperature coefficient within specification: ±200ppm/°C
• Operating temperature range compatibility: minimum -55°C, maximum ≥125°C
• RoHS3 compliance
• MSL rating of 1 (Unlimited)

Two substitute parts meet these criteria: CRCW02014K30FNED (Vishay Dale) and ERJ-1GNF4301C (Panasonic Electronic Components).

Parameter Comparison

Engineering Selection Recommendations

All three components—AF0201FR-074K3L, CRCW02014K30FNED, and ERJ-1GNF4301C—are active production parts with ROHS3 compliance and REACH unaffected status. The CRCW02014K30FNED offers an extended operating temperature range to 155°C compared to the 125°C maximum of the original and Panasonic parts. Selection between these substitutes depends on application-specific temperature requirements and supply chain availability. All parts are suitable for direct substitution in circuits designed for the AF0201FR-074K3L specifications.

Frequently Asked Questions (FAQ)

Q: Can CRCW02014K30FNED replace AF0201FR-074K3L in all applications?

A: Yes, within the specified operating temperature range. The CRCW02014K30FNED supports temperatures up to 155°C, exceeding the AF0201FR-074K3L maximum of 125°C. All other electrical and mechanical parameters are equivalent.

Q: Are there any package compatibility issues between these substitutes?

A: No. All three parts use identical 0201 (0603 Metric) packaging with matching dimensions (0.024" L x 0.012" W, 0.60mm x 0.30mm) and maximum seated height (0.010", 0.26mm). They are mechanically interchangeable on PCBs designed for 0201 components.

Q: Do all substitute parts meet automotive qualification requirements?

A: The AF0201FR-074K3L carries AEC-Q200 automotive rating. The CRCW02014K30FNED and ERJ-1GNF4301C do not list AEC-Q200 certification in the provided specifications. If automotive qualification is mandatory, the original AF0201FR-074K3L is the specified choice.

Q: What is the tolerance specification for these resistors?

A: All three parts maintain ±1% tolerance with a temperature coefficient of ±200ppm/°C across the operating temperature range, ensuring consistent performance in precision applications.

Q: Are moisture sensitivity considerations the same across all parts?

A: Yes. All three components have MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
