Key Parameters

Substitute Part Grouping Explanation

Substitution logic is based on strict electrical and mechanical parameter matching. All substitute parts listed maintain identical specifications for resistance (68 kOhms), tolerance (±1%), package format (0805 / 2012 Metric), composition (thick film), operating temperature range (-55°C ~ 155°C), temperature coefficient (±100ppm/°C), termination count (2), RoHS compliance (ROHS3), and MSL rating (1 / Unlimited).

Direct Substitutes (Identical Power Rating - 0.125W / 1/8W): These parts are functionally equivalent with no derating or circuit redesign required. They share all critical parameters including the 0.125W power rating.

Similar Substitutes (Enhanced Power Rating - 0.5W / 1/2W): These parts exceed the original power specification with 0.5W (1/2W) rating. They are electrically and mechanically compatible but provide additional thermal margin. Selection depends on circuit design requirements and available board space.

Application-Specific Variants: Certain substitutes include automotive AEC-Q200 qualification or anti-sulfur features. These are suitable for applications requiring automotive-grade reliability or corrosive environment resistance.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): CR0805-FX-6802ELF (Bourns), CRG0805F68K (TE Connectivity), RC0805FR-0768KL (YAGEO), and RMCF0805FT68K0 (Stackpole) are functionally equivalent to the RC2012F683CS. All maintain 0.125W power rating, ±1% tolerance, and -55°C ~ 155°C operating range. Selection among these options is based on packaging preference (Cut Tape vs. Tape & Reel) and inventory availability.

For Automotive Applications: ERJ-6ENF6802V (Panasonic), RMCF0805FT68K0 (Stackpole), AC0805FR-0768KL (YAGEO), and CRCW080568K0FKEA (Vishay Dale) carry AEC-Q200 automotive qualification. These are suitable for automotive-grade circuit designs requiring enhanced reliability documentation.

For Enhanced Thermal Performance: CRCW080568K0FKEAHP (Vishay Dale), ERJ-UP6F6802V (Panasonic), and RCS080568K0FKEA (Vishay Dale) provide 0.5W (1/2W) power rating with pulse withstanding capability. These are applicable when circuit analysis indicates higher transient power dissipation or when additional thermal margin is required for reliability.

For Corrosive Environments: ERJ-UP6F6802V (Panasonic) includes anti-sulfur feature, suitable for applications exposed to sulfur-containing atmospheres or corrosive industrial environments.

All listed substitutes maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory and handling compatibility with the original part.

Frequently Asked Questions (FAQ)

Q: Can CR0805-FX-6802ELF replace RC2012F683CS directly without circuit modification? A: Yes. CR0805-FX-6802ELF is a direct substitute with identical electrical specifications (68 kOhms ±1%, 0.125W) and mechanical compatibility (0805 package, -55°C ~ 155°C operating range). No circuit redesign is required.

Q: What is the difference between 0.125W and 0.5W rated resistors in the same 0805 package? A: The 0.5W variants (CRCW080568K0FKEAHP, ERJ-UP6F6802V, RCS080568K0FKEA) provide four times the power dissipation capacity within the same physical footprint. They are suitable for circuits with higher transient power requirements or when additional thermal margin is desired. The 0.125W rating is sufficient for standard signal-level applications.

Q: Are AEC-Q200 qualified parts necessary for non-automotive applications? A: AEC-Q200 qualification is not required for non-automotive circuits. However, these parts (ERJ-6ENF6802V, RMCF0805FT68K0, AC0805FR-0768KL, CRCW080568K0FKEA) undergo enhanced reliability testing and are suitable for any application requiring higher quality assurance documentation.

Q: What is the significance of "Moisture Resistant" and "Anti-Sulfur" features? A: Moisture Resistant construction (CR0805-FX-6802ELF, RC0805FR-0768KL, AC0805FR-0768KL) provides enhanced protection against humidity ingress. Anti-Sulfur feature (ERJ-UP6F6802V) protects against sulfur-containing atmospheric corrosion. These features are beneficial for applications in humid or chemically aggressive environments.

Q: Can I use Cut Tape (CT) packaging interchangeably with Tape & Reel (TR) packaging? A: Cut Tape and Tape & Reel are different supply formats for the same component. Cut Tape is suitable for small-quantity manual assembly or prototyping. Tape & Reel is optimized for high-volume automated pick-and-place assembly. The electrical and mechanical specifications are identical; packaging choice depends on assembly process requirements and order quantity.

Q: What does "Pulse Withstanding" capability indicate? A: Pulse Withstanding (CRCW080568K0FKEAHP, ERJ-UP6F6802V, RCS080568K0FKEA) indicates the resistor can tolerate brief high-power transient events exceeding the nominal power rating. This feature is valuable in circuits with inductive switching, surge protection, or other transient-prone applications.

Q: Are all listed substitutes ROHS3 compliant? A: Yes. All substitute parts listed carry ROHS3 Compliant status, ensuring compatibility with environmental regulations and procurement requirements matching the original RC2012F683CS.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity? A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. These parts do not require special dry-pack storage or baking procedures before soldering, simplifying inventory management and assembly logistics.
