Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F6650CS is determined by strict equivalence across the following critical parameters: resistance value (665 Ohms), tolerance (±1%), package format (0402 / 1005 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance certifications (RoHS3, REACH Unaffected, EAR99).

Direct Equivalents maintain identical power rating (0.063W / 1/16W), packaging format (Tape & Reel), and all electrical specifications. These parts are pin-for-pin compatible with no design modifications required.

Upgrade Substitutes provide higher power rating (0.1W / 1/10W) while maintaining all other electrical and mechanical parameters. These parts are physically and electrically compatible and offer enhanced power dissipation capability.

Similar Substitutes match all core electrical parameters and package specifications but may include automotive-grade certifications (AEC-Q200) or alternative packaging formats (Cut Tape & Digi-Reel). These parts are functionally equivalent with potential application-specific advantages.

Parameter Comparison

CRCW0402665RFKED (Vishay Dale) is a similar substitute with Automotive AEC-Q200 certification and Cut Tape & Digi-Reel packaging. Selection is appropriate for automotive applications where alternative packaging formats are acceptable.

RMCF0402FT665R (Stackpole Electronics Inc) is a similar substitute with Automotive AEC-Q200 certification and Tape & Reel packaging. Selection is appropriate for automotive-grade applications requiring standard reel packaging.

All substitute parts maintain RoHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level 1 (Unlimited), ensuring regulatory and environmental compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-6650GLF replace RC1005F6650CS in all applications?

A: CR0402-FX-6650GLF is a direct electrical and mechanical equivalent. Both parts share identical resistance (665 Ohms), tolerance (±1%), power rating (0.063W), package format (0402), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Substitution is valid for all applications where the original part is specified, with no design modifications required.

Q: What is the difference between the main part and ERJ-2RKF6650X?

A: ERJ-2RKF6650X differs in power rating (0.1W versus 0.063W) and includes Automotive AEC-Q200 certification. All other electrical parameters remain identical. The higher power rating allows greater thermal dissipation capability. This part is suitable for automotive applications or designs requiring enhanced power handling within the same package footprint.

Q: Are automotive-grade parts (AEC-Q200) compatible with non-automotive applications?

A: Automotive-grade parts such as ERJ-2RKF6650X, CRCW0402665RFKED, and RMCF0402FT665R meet or exceed industrial-grade specifications. These parts are fully compatible with non-automotive applications. AEC-Q200 certification indicates additional qualification testing and reliability assurance, making these parts suitable for any application requiring the specified electrical characteristics.

Q: Does packaging format (Tape & Reel versus Cut Tape & Digi-Reel) affect electrical performance?

A: Packaging format does not affect electrical performance or component specifications. Tape & Reel and Cut Tape & Digi-Reel are alternative supply formats for the same component. Selection between formats depends on manufacturing process requirements, pick-and-place equipment compatibility, and supply chain preferences.

Q: Can I use CRCW0402665RFKED as a direct replacement for RC1005F6650CS?

A: CRCW0402665RFKED is electrically and mechanically equivalent with identical resistance, tolerance, power rating, package, and temperature specifications. The primary difference is packaging format (Cut Tape & Digi-Reel versus Tape & Reel) and the addition of Automotive AEC-Q200 certification. Substitution is valid if the alternative packaging format is compatible with your manufacturing process.

Q: What does Moisture Sensitivity Level 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. The part can be stored and handled without special moisture control measures, desiccant packaging, or bake-out procedures prior to soldering. All listed substitute parts maintain this same MSL rating.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (CR0402-FX-6650GLF, RC0402FR-07665RL, ERJ-2RKF6650X, CRCW0402665RFKED, and RMCF0402FT665R) are RoHS3 compliant and REACH Unaffected, matching the original RC1005F6650CS specification.
