Engineering Selection Recommendations

For Active Production with Automotive Requirements: ACASA1001E1001P1AT is the direct upgrade path for automotive applications. It maintains AEC-Q200 qualification, extends operating temperature to 155°C matching the original specification, increases power per element to 125mW, and improves tolerance to ±0.25% with ±25ppm/°C temperature coefficient. However, this part is marked "Not For New Designs" and should be evaluated for long-term availability.

For Active Production with Standard Requirements: CAY16-1001F4LF from Bourns Inc. is an active production alternative with matching ±1% tolerance and ±200ppm/°C temperature coefficient. Operating temperature is limited to 125°C, and power per element is reduced to 62.5mW. This part is suitable for applications not requiring the full 155°C upper temperature limit or maximum power dissipation of the original.

For Enhanced Tolerance in Non-Automotive Applications: ACASA100121001P100 provides ±0.5% tolerance and ±50ppm/°C temperature coefficient with active product status. Operating temperature is limited to 125°C. This part is appropriate for voltage divider applications requiring improved accuracy without automotive qualification requirements.

For Precision Applications: ACASA1001E1001P100 offers the highest tolerance specification at ±0.25% with ±25ppm/°C temperature coefficient and ±0.05% resistor matching ratio. This part is marked "Not For New Designs" and operating temperature is limited to 125°C.

Frequently Asked Questions (FAQ)

Q: Can CAY16-1001F4LF replace RAVF164DFT1K00 in automotive applications? A: No. CAY16-1001F4LF lacks AEC-Q200 qualification and has a maximum operating temperature of 125°C versus the original 155°C. For automotive use, ACASA1001E1001P1AT is the qualified substitute.

Q: What is the difference between ACASA1001E1001P100 and ACASA1001E1001P1AT? A: Both parts share ±0.25% tolerance and ±25ppm/°C temperature coefficient. ACASA1001E1001P1AT has 125mW power per element (versus 100mW), extends operating temperature to 155°C, and includes AEC-Q200 automotive qualification. ACASA1001E1001P100 is limited to 125°C and lacks automotive qualification.

Q: Are all substitute parts pin-compatible with RAVF164DFT1K00? A: Yes. All substitute parts have 8 pins in 1206 (3216 Metric) package with Convex, Long Side Terminals configuration, ensuring direct PCB footprint compatibility.

Q: Which substitute offers the best temperature stability? A: ACASA1001E1001P100 and ACASA1001E1001P1AT both provide ±25ppm/°C temperature coefficient, superior to the original ±200ppm/°C specification.

Q: Can I use a substitute with lower power per element rating? A: CAY16-1001F4LF has 62.5mW power per element versus the original 100mW. Substitution is valid only if your application does not require the full 100mW dissipation per resistor element.

Q: What is the inventory status of these substitutes? A: ACASA100121001P100 has 6,100 units in stock. ACASA1001E1001P100 has 23,542 units. ACASA1001E1001P1AT has 4,555 units. CAY16-1001F4LF has 20,100 units in stock.
