Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-6652GLF be used as a direct replacement for RC1005F6652CS?

A: Yes. CR0402-FX-6652GLF is a direct equivalent substitute. Both parts share identical resistance value (66.5 kOhms), tolerance (±1%), power rating (0.063W), package (0402), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, MSL 1). The only difference is manufacturer identity (Bourns vs. Samsung Electro-Mechanics).

Q: What is the difference between RC0402FR-0766K5L and RC1005F6652CS?

A: RC0402FR-0766K5L (YAGEO) and RC1005F6652CS (Samsung Electro-Mechanics) are functionally equivalent. Both are 66.5 kOhms ±1% thick film resistors in 0402 package with 0.063W power rating and identical temperature specifications. Both feature moisture-resistant construction and ROHS3 compliance. The parts differ only in manufacturer and product series designation.

Q: Can I use ERJ-2RKF6652X as a substitute if my design specifies RC1005F6652CS?

A: ERJ-2RKF6652X is a compatible upgrade substitute. It maintains all electrical parameters (66.5 kOhms, ±1%, ±100ppm/°C, -55°C to 155°C) and package specifications (0402) of the original part. The key difference is higher power rating (0.1W vs. 0.063W), which provides additional thermal margin. This upgrade is backward compatible for applications not requiring exact power matching. ERJ-2RKF6652X also includes AEC-Q200 automotive qualification.

Q: Are automotive-grade parts (AEC-Q200) suitable for non-automotive applications?

A: Yes. Automotive-grade parts such as AC0402FR-0766K5L, AF0402FR-0766K5L, CRCW040266K5FKED, and RMCF0402FT66K5 meet or exceed the electrical and reliability requirements of standard industrial-grade components. These parts can be used in any application where the original RC1005F6652CS specification is acceptable. AEC-Q200 qualification represents additional quality assurance and is not restrictive to automotive use only.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 rating indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Both the main part (RC1005F6652CS) and all substitute parts listed carry MSL 1 rating, meaning they can be stored and handled under standard conditions without desiccant packaging or time-limited exposure requirements.

Q: Can I mix different manufacturers' parts in the same production run?

A: Yes. All listed substitute parts maintain identical electrical specifications, package dimensions, and compliance certifications. From an engineering standpoint, mixing manufacturers is acceptable when parts meet the same specification requirements. However, procurement and quality assurance procedures should verify that mixed sourcing aligns with your organization's supply chain policies.

Q: What is the difference between "Moisture Resistant" and standard thick film resistors?

A: Moisture-resistant thick film resistors (RC1005F6652CS, RC0402FR-0766K5L, AC0402FR-0766K5L, AF0402FR-0766K5L) incorporate protective coatings or materials that reduce moisture absorption and improve long-term reliability in humid environments. Standard thick film resistors (CR0402-FX-6652GLF) lack this specific feature designation but maintain equivalent electrical performance and MSL 1 rating. Selection depends on application environment requirements.

Q: Why does AF0402FR-0766K5L include "Anti-Sulfur" in its description?

A: Anti-sulfur protection refers to resistance to sulfur-containing atmospheric contaminants that can degrade component performance in certain industrial or marine environments. AF0402FR-0766K5L is suitable for applications exposed to sulfur-containing gases or corrosive atmospheres. For standard applications, this feature is not required but provides additional environmental protection if needed.

Q: Are all substitute parts available in Tape & Reel packaging?

A: All listed substitute parts are available in Tape & Reel (TR) packaging, matching the original RC1005F6652CS packaging format. CRCW040266K5FKED is also available in Cut Tape (CT) and Digi-Reel® formats. Tape & Reel packaging is standard for automated assembly processes and ensures compatibility with pick-and-place equipment.
