Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AC0201FR-073RL is determined by the following critical parameters:

• Resistance value: 3 Ohms (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: -100 / +350 ppm/°C (exact match required)
• Moisture sensitivity level: MSL 1 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The RC0201FR-073RL meets all critical electrical and mechanical parameters required for direct substitution. Both parts share identical resistance, tolerance, power rating, package dimensions, composition, and compliance certifications. Differences in operating temperature range and automotive qualification do not prevent functional substitution in applications where the RC0201FR-073RL specifications are acceptable.

Parameter Comparison

Engineering Selection Recommendations

Both AC0201FR-073RL and RC0201FR-073RL are active production components from YAGEO with ROHS3 compliance and MSL 1 moisture sensitivity rating. The AC0201FR-073RL includes AEC-Q200 automotive qualification and supports an operating temperature range to 155°C. The RC0201FR-073RL operates to 125°C maximum and does not carry automotive qualification.

Selection between these parts depends on application requirements. For automotive applications requiring AEC-Q200 qualification and extended temperature operation to 155°C, the AC0201FR-073RL is the specified choice. For non-automotive applications or those with maximum operating temperatures at or below 125°C, the RC0201FR-073RL provides equivalent electrical performance and compliance characteristics.

Frequently Asked Questions (FAQ)

Q: Can RC0201FR-073RL replace AC0201FR-073RL in automotive applications?

A: The RC0201FR-073RL does not carry AEC-Q200 automotive qualification. Substitution in automotive applications is not supported unless the application requirements do not mandate AEC-Q200 certification.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 0201 (0603 Metric) package with identical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm).

Q: What is the temperature difference between these parts?

A: The AC0201FR-073RL operates from -55°C to 155°C. The RC0201FR-073RL operates from -55°C to 125°C. The AC0201FR-073RL provides 30°C additional high-temperature capability.

Q: Are both parts RoHS compliant?

A: Yes. Both AC0201FR-073RL and RC0201FR-073RL are ROHS3 compliant with MSL 1 moisture sensitivity rating.

Q: What is the primary difference between these parts?

A: The AC0201FR-073RL includes AEC-Q200 automotive qualification and extended operating temperature to 155°C. The RC0201FR-073RL is a general-purpose variant with standard operating temperature to 125°C. All electrical parameters are identical.
