RC2012F64R9CS Equivalent & Substitute Parts Reference

Part Overview

The RC2012F64R9CS is a 64.9 Ohm ±1% 1/8W (0.125W) chip resistor manufactured by Samsung Electro-Mechanics in 0805 (2012 Metric) package format. This thick film, moisture-resistant component operates across -55°C to 155°C with a temperature coefficient of ±100ppm/°C. The part is Active status and ROHS3 compliant with MSL 1 rating. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits alternative qualified manufacturers meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F64R9CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (64.9 Ohms), tolerance (±1%), power rating (0.125W), and temperature coefficient (±100ppm/°C) must match exactly.

Mechanical Specifications: Package type (0805 / 2012 Metric), composition (Thick Film), and physical dimensions (0.079" L x 0.049" W) must be identical.

Environmental & Compliance: Operating temperature range (-55°C ~ 155°C), Moisture Sensitivity Level (MSL 1), RoHS3 compliance, and REACH unaffected status must be maintained.

Packaging Format: Tape & Reel (TR) packaging must be consistent for automated assembly compatibility.

All identified substitute parts meet these criteria. Additional features such as Automotive AEC-Q200 qualification represent enhanced capability and do not disqualify substitution.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are functionally equivalent to the RC2012F64R9CS based on electrical and mechanical parameter alignment. Selection among these alternatives is determined by availability, supply chain considerations, and application-specific requirements.

RC0805FR-0764R9L (YAGEO): Direct equivalent with identical feature set. Moisture-resistant thick film composition. Lowest seated height (0.60mm) among standard variants. Suitable for space-constrained PCB layouts.

CRCW080564R9FKEA (Vishay Dale): Includes Automotive AEC-Q200 qualification. Lowest seated height (0.50mm). Appropriate for automotive and high-reliability applications requiring enhanced qualification documentation.

ERJ-6ENF64R9V (Panasonic): Includes Automotive AEC-Q200 qualification. Highest seated height (0.70mm). Suitable for automotive applications with standard PCB clearance specifications.

RMCF0805FT64R9 (Stackpole Electronics): Includes Automotive AEC-Q200 qualification. Seated height (0.65mm) within standard range. Appropriate for automotive and industrial applications.

All parts maintain Active product status, ROHS3 compliance, and MSL 1 rating. Selection should prioritize component availability and established supply chain relationships.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-0764R9L replace RC2012F64R9CS in existing designs?

A: Yes. Both components share identical electrical specifications (64.9 Ohms ±1%, 0.125W), thermal characteristics (±100ppm/°C, -55°C to 155°C), and package format (0805 / 2012 Metric). The seated height difference (0.60mm vs 0.66mm) is within standard PCB assembly tolerances and does not affect circuit functionality.

Q: What is the difference between standard and AEC-Q200 qualified variants?

A: CRCW080564R9FKEA, ERJ-6ENF64R9V, and RMCF0805FT64R9 include Automotive AEC-Q200 qualification, indicating compliance with automotive reliability and testing standards. The RC2012F64R9CS and RC0805FR-0764R9L do not carry this designation. AEC-Q200 qualification is required for automotive applications; standard variants are suitable for general industrial and consumer electronics.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All identified substitute parts are supplied in Tape & Reel (TR) format, ensuring compatibility with automated pick-and-place assembly equipment.

Q: Do seated height variations affect PCB assembly?

A: Seated height variations (0.50mm to 0.70mm) are within standard 0805 package tolerances and do not affect automated assembly processes or circuit performance. Component selection based on seated height is appropriate only for applications with specific clearance constraints.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original RC2012F64R9CS specifications.

Q: Which substitute part offers the best availability?

A: ERJ-6ENF64R9V (Panasonic) shows the highest inventory level (108,147 pcs), followed by RC0805FR-0764R9L (YAGEO) with 89,064 pcs. Availability should be confirmed with current suppliers for time-sensitive procurement.
