Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F6654CS are identified based on strict equivalence across the following critical parameters:

Electrical Equivalence: Resistance value of 6.65 MOhms with ±1% tolerance, power rating of 0.125W, and temperature coefficient of ±100ppm/°C must match exactly.

Mechanical Compatibility: Package format must be 0805 (2012 Metric) with compatible physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and two terminations.

Environmental & Compliance: Operating temperature range of -55°C to 155°C, ROHS3 compliance, MSL 1 rating, and thick film composition are required for substitution validity.

Composition & Features: Thick film construction is mandatory. Moisture resistance is a baseline requirement; anti-sulfur properties are additional features that may vary between manufacturers without affecting core substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

The RC0805FR-076M65L (YAGEO) is a valid substitute for the RCS2012F6654CS (Samsung Electro-Mechanics) based on complete electrical and mechanical equivalence. Both components share identical resistance values, tolerance specifications, power ratings, package formats, temperature coefficients, and operating temperature ranges. Both maintain ROHS3 compliance and MSL 1 ratings, confirming regulatory alignment.

The seated height differential (0.66mm versus 0.60mm) falls within acceptable PCB assembly tolerances for 0805 package components and does not impact functional performance or board-level compatibility. Both components are classified as Active products with continuous manufacturer support.

Selection between these parts may be determined by inventory availability, supply chain logistics, or established procurement preferences, as electrical and mechanical performance characteristics are equivalent.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-076M65L replace RCS2012F6654CS in existing designs?

A: Yes. Both components meet identical electrical specifications (6.65 MOhms ±1%, 0.125W, ±100ppm/°C) and mechanical requirements (0805 package, 2.00mm x 1.25mm dimensions). The 0.06mm height difference is within standard PCB assembly tolerances and does not affect circuit performance or board layout.

Q: Are there differences in moisture resistance between these parts?

A: Both components carry MSL 1 (Unlimited) ratings and are moisture resistant. The RCS2012F6654CS includes additional anti-sulfur properties, but both parts meet the baseline moisture resistance requirement for 0805 thick film resistors.

Q: Do both parts comply with environmental regulations?

A: Yes. Both the RCS2012F6654CS and RC0805FR-076M65L are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes (8533.21.0030).

Q: What is the temperature operating range for these substitutes?

A: Both components operate across -55°C to 155°C with a temperature coefficient of ±100ppm/°C, ensuring equivalent thermal performance in industrial and commercial applications.

Q: Are packaging formats identical?

A: Both components use 0805 (2012 Metric) package format with two terminations. Physical dimensions are 0.079" L x 0.049" W (2.00mm x 1.25mm), ensuring direct PCB footprint compatibility.
