Parameter Comparison

Engineering Selection Recommendations

The RC0805FR-078M66L from YAGEO is a direct electrical and mechanical equivalent to the RC2012F8664CS from Samsung Electro-Mechanics. Both components are active production parts with identical electrical specifications, package dimensions, and compliance certifications. The seated height difference of 0.002" (0.06mm) between the two parts falls within standard PCB assembly tolerances and does not affect functional performance or board-level compatibility.

Selection between these parts may be based on inventory availability, supply chain considerations, or procurement preferences. The YAGEO part currently has higher inventory availability at 18,450 pieces compared to 954 pieces for the Samsung part. Both parts carry ROHS3 compliance and REACH unaffected status, making them suitable for applications requiring environmental regulatory adherence.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-078M66L be used as a direct replacement for RC2012F8664CS in existing designs?

A: Yes. Both parts share identical electrical specifications (8.66 MOhms ±1%, 0.125W), identical package format (0805/2012 Metric), and identical operating parameters. The 0.002" difference in seated height is within standard PCB assembly tolerances and does not affect circuit performance or board layout.

Q: Are there any compliance differences between these two parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. They are functionally equivalent from a regulatory and environmental standpoint.

Q: What determines whether a part can substitute for RC2012F8664CS?

A: Substitution requires matching all critical parameters: resistance value (8.66 MOhms), tolerance (±1%), power rating (0.125W), package format (0805), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, REACH unaffected).

Q: Does the slight difference in seated height affect PCB assembly?

A: No. The 0.002" (0.06mm) difference in maximum seated height between the Samsung part (0.66mm) and YAGEO part (0.60mm) is within standard surface mount assembly tolerances and does not impact solder joint quality, component placement, or circuit functionality.

Q: Are both parts available in the same packaging format?

A: Yes. Both RC2012F8664CS and RC0805FR-078M66L are supplied in Tape & Reel (TR) packaging, which is standard for high-volume surface mount assembly operations.
