Parameter Comparison

Engineering Selection Recommendations

RK73H1HTTCM2200F (KOA Speer Electronics, Inc.): This part is the manufacturer-recommended substitute from KOA Speer Electronics, Inc. It maintains identical electrical and mechanical specifications to the RK73H1HTTC2200F while carrying Active product status. The part is ROHS3 compliant and rated for AEC-Q200 automotive applications. However, moisture resistance is not explicitly specified in the provided data for this variant, which may be a consideration for applications requiring confirmed moisture protection.

AC0201FR-07220RL (YAGEO): This part is a direct cross-reference alternative manufactured by YAGEO. It provides identical electrical performance and package specifications with confirmed moisture-resistant construction and AEC-Q200 automotive qualification. The AC0201FR-07220RL carries Active product status and ROHS3 compliance. This part is suitable for applications requiring an alternative manufacturer source while maintaining full electrical and environmental performance equivalence.

Both substitute parts are appropriate for replacing the RK73H1HTTC2200F in new designs and ongoing production applications where active component status is required.

Frequently Asked Questions (FAQ)

Q: Can the RK73H1HTTCM2200F be used as a direct replacement for the RK73H1HTTC2200F? A: Yes. Both parts share identical resistance (220 Ohms), tolerance (±1%), power rating (0.05W), package (0201), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), AEC-Q200 rating, physical dimensions, and RoHS compliance. The primary difference is product status: RK73H1HTTCM2200F is Active while RK73H1HTTC2200F is Not For New Designs.

Q: What is the difference between RK73H1HTTC2200F and AC0201FR-07220RL? A: Both parts are electrically and mechanically identical in all critical parameters: 220 Ohms ±1%, 0.05W, 0201 package, thick film composition, ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range, AEC-Q200 rating, and ROHS3 compliance. The primary difference is manufacturer: KOA Speer Electronics, Inc. versus YAGEO. Both are Active products with confirmed moisture-resistant construction.

Q: Are these parts suitable for automotive applications? A: Yes. All three parts carry AEC-Q200 automotive qualification, confirming suitability for automotive-grade applications with appropriate reliability and performance standards.

Q: What is the significance of the 0201 package designation? A: The 0201 package (0603 Metric) is a surface-mount chip resistor measuring 0.024" L x 0.012" W (0.60mm x 0.30mm) with a maximum seated height of 0.010" (0.26mm). All substitute parts use this identical package, ensuring mechanical compatibility with existing PCB layouts and assembly processes.

Q: Can I use these parts interchangeably in my design? A: Yes, provided your application requirements match the specified parameters: 220 Ohms resistance, ±1% tolerance, 0.05W power rating, 0201 package, thick film composition, -55°C ~ 155°C operating temperature, and AEC-Q200 automotive qualification. All three parts meet these criteria.

Q: What does MSL 1 (Unlimited) mean? A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life without special moisture-control storage requirements, making it suitable for standard warehouse and manufacturing environments without desiccant packaging or controlled humidity conditions.
