Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F680CS are qualified based on the following electrical and mechanical parameters:

Mandatory Matching Parameters:

• Resistance value: 68 Ohms
• Tolerance: ±1%
• Package format: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Termination count: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variation:

• Power rating: Substitute parts may have equal or higher power dissipation (0.75W or greater is acceptable as an upgrade)
• Manufacturer: Different manufacturers permitted
• Series designation: May differ
• Packaging format: Tape & Reel acceptable as alternative to standard packaging

The identified substitutes AC2010FK-0768RL and RC2010FK-0768RL meet all mandatory parameters and provide increased power rating of 0.75W (3/4W), representing a performance upgrade while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

RC5025F680CS (Samsung Electro-Mechanics) Primary selection for applications requiring the specified 0.667W power rating. Active product status with established supply availability. Suitable for standard industrial and consumer applications with moisture-resistant thick film construction.

AC2010FK-0768RL (YAGEO) Automotive-grade substitute with AEC-Q200 qualification. Provides 0.75W power rating upgrade. Recommended for automotive applications, harsh environment deployments, or designs requiring enhanced reliability margins. ROHS3 compliant with identical electrical characteristics and package compatibility.

RC2010FK-0768RL (YAGEO) Industrial-grade substitute with 0.75W power rating upgrade. Provides performance enhancement without automotive-specific qualification. Recommended for general industrial applications where increased power dissipation margin is beneficial. ROHS3 compliant with full mechanical and electrical compatibility.

All three parts maintain identical resistance, tolerance, temperature coefficient, operating temperature range, and package dimensions. Selection between substitutes depends on application requirements (automotive vs. industrial) and desired power rating margin.

Frequently Asked Questions (FAQ)

Q: Can AC2010FK-0768RL replace RC5025F680CS in any application? A: AC2010FK-0768RL is electrically and mechanically compatible with RC5025F680CS. The higher 0.75W power rating provides additional thermal margin. The automotive AEC-Q200 qualification makes it suitable for automotive and high-reliability applications. Substitution is valid for all applications where RC5025F680CS is specified.

Q: What is the difference between AC2010FK-0768RL and RC2010FK-0768RL? A: Both parts share identical electrical specifications (68 Ohms ±1%, 0.75W, ±100ppm/°C) and package format (2010 Metric). AC2010FK-0768RL includes automotive AEC-Q200 qualification; RC2010FK-0768RL is industrial-grade. Selection depends on application requirements. Both are ROHS3 compliant with unlimited MSL.

Q: Are the physical dimensions identical between all three parts? A: Yes. All three parts use the 2010 (5025 Metric) package with dimensions of 0.197" L x 0.098" W (5.00mm x 2.50mm). Maximum seated height is 0.026" (0.65-0.66mm). PCB footprints and assembly processes are identical.

Q: What does the ±1% tolerance mean for the 68 Ohm resistor? A: The resistance value will be within the range of 67.32 Ohms to 68.68 Ohms at 25°C. All three parts maintain this tolerance specification.

Q: Can these parts be used in high-temperature applications? A: Yes. All three parts operate across -55°C to 155°C. Temperature coefficient of ±100ppm/°C applies across this range. Resistance variation due to temperature is predictable and consistent across all three parts.

Q: What is the significance of MSL 1 (Unlimited)? A: Moisture Sensitivity Level 1 indicates unlimited shelf life without special moisture control. These parts do not require dry-pack storage or baking before reflow soldering, simplifying handling and assembly processes.

Q: Are these parts RoHS compliant? A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for EU and global markets.

Q: What is the difference in power rating between the main part and substitutes? A: RC5025F680CS is rated for 0.667W (2/3W). Both AC2010FK-0768RL and RC2010FK-0768RL are rated for 0.75W (3/4W). The higher rating provides additional thermal margin and is fully backward compatible for applications requiring the lower rating.
