Parameter Comparison

Engineering Selection Recommendations

All three components—AF0201FR-0735K7L, CRCW020135K7FNED, and ERJ-1GNF3572C—are active production parts with ROHS3 compliance and MSL Level 1 rating. The CRCW020135K7FNED from Vishay Dale offers an extended operating temperature range to 155°C, providing additional thermal margin in high-temperature applications. The AF0201FR-0735K7L and ERJ-1GNF3572C both operate to 125°C. Selection should be based on application thermal requirements, supply chain availability, and design qualification status with the selected manufacturer.

Frequently Asked Questions (FAQ)

Q: Can CRCW020135K7FNED replace AF0201FR-0735K7L in all applications?

A: Yes, the CRCW020135K7FNED meets all electrical and mechanical specifications. The extended operating temperature range (to 155°C versus 125°C) provides additional capability without reducing performance in standard temperature applications.

Q: Are there differences in the anti-sulfur coating between these parts?

A: The AF0201FR-0735K7L specifies anti-sulfur coating as a feature. The CRCW020135K7FNED and ERJ-1GNF3572C do not list this feature in the provided specifications. Applications requiring anti-sulfur protection should confirm coating specifications with the manufacturer before substitution.

Q: Do all three parts use identical 0201 package dimensions?

A: Yes. All three components share identical package dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) with maximum seated height of 0.010" (0.26mm). They are mechanically interchangeable on PCB layouts designed for 0201 format.

Q: What is the significance of the ±200ppm/°C temperature coefficient?

A: The temperature coefficient indicates resistance change per degree Celsius. All three parts share this specification, ensuring equivalent thermal stability across the operating temperature range.

Q: Are all parts suitable for automotive applications?

A: The AF0201FR-0735K7L carries AEC-Q200 automotive qualification. The CRCW020135K7FNED and ERJ-1GNF3572C do not list automotive ratings in the provided specifications. Automotive applications should verify qualification status with manufacturers before substitution.
