Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (18.2 Ohms), tolerance (±1%), power rating (0.05W), composition (thick film), package format (0201), temperature coefficient (±200ppm/°C), and compliance certifications (ROHS3, MSL 1). Operating temperature range variations are permitted within the specified limits. All identified substitutes maintain these core electrical and mechanical specifications, enabling direct functional replacement in circuit applications.

Engineering Selection Recommendations

All substitute parts maintain full electrical and mechanical equivalence to the AC0201FR-0718R2L. Selection between alternatives should be based on availability and supply chain requirements. RC0201FR-0718R2L (YAGEO) and ERJ-1GNF18R2C (Panasonic) operate within a reduced upper temperature limit of 125°C compared to the primary part's 155°C specification; applications requiring the full -55°C to 155°C range should prioritize AC0201FR-0718R2L or CRCW020118R2FNED (Vishay Dale). All parts carry ROHS3 compliance and MSL 1 rating, confirming suitability for standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can RC0201FR-0718R2L replace AC0201FR-0718R2L in all applications? A: RC0201FR-0718R2L is electrically equivalent with identical resistance, tolerance, power rating, and package specifications. The operating temperature range differs: RC0201FR-0718R2L is rated to 125°C maximum versus 155°C for AC0201FR-0718R2L. Applications operating above 125°C require the primary part or CRCW020118R2FNED.

Q: What is the significance of the 0201 package designation? A: The 0201 package (0603 metric) defines the physical dimensions: 0.024" L × 0.012" W (0.60mm × 0.30mm) with maximum seated height of 0.010" (0.26mm). All substitute parts share identical package specifications, ensuring PCB footprint and assembly compatibility.

Q: Are all substitute parts automotive-qualified? A: AC0201FR-0718R2L carries AEC-Q200 automotive qualification. RC0201FR-0718R2L, CRCW020118R2FNED, and ERJ-1GNF18R2C do not list AEC-Q200 ratings in provided specifications. Applications requiring automotive qualification should use AC0201FR-0718R2L or verify AEC-Q200 status with manufacturers.

Q: What does MSL 1 (Unlimited) mean for component handling? A: MSL 1 rating indicates unlimited shelf life without moisture baking requirements. All parts in this comparison carry MSL 1 classification, permitting standard storage and handling procedures without special environmental controls.

Q: How do tolerance and temperature coefficient affect circuit performance? A: All parts maintain ±1% tolerance and ±200ppm/°C temperature coefficient. These specifications determine resistor accuracy across temperature variations. Equivalent values ensure predictable circuit behavior across the specified operating range.
