Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F6652CS is determined by the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Resistance value: 66.5 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match Exactly):

• Package type: 0805 (2012 Metric)
• Physical dimensions: 0.079" L × 0.049" W (2.00mm × 1.25mm)
• Number of terminations: 2

Compliance Parameters (Must Match):

• RoHS3 Compliant
• Moisture Sensitivity Level: MSL 1 (Unlimited)

All identified substitute parts meet these core requirements. Variations in seated height (0.020" to 0.028") and packaging format (Cut Tape versus Tape & Reel) do not affect electrical or functional compatibility. Additional features such as Automotive AEC-Q200 certification or High Voltage rating represent enhanced specifications that provide equivalent or superior performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are Active status components with ROHS3 compliance and MSL 1 rating, confirming suitability for direct replacement in the RC2012F6652CS application.

For general industrial applications: RC0805FR-0766K5L (YAGEO), RMCF0805FT66K5 (Stackpole Electronics Inc), or ERJ-6ENF6652V (Panasonic) provide equivalent performance with high inventory availability.

For automotive applications requiring AEC-Q200 certification: KTR10EZPF6652 (Rohm Semiconductor), RMCF0805FT66K5 (Stackpole Electronics Inc), ERJ-6ENF6652V (Panasonic), or CRCW080566K5FKEA (Vishay Dale) meet automotive qualification standards.

For high-voltage circuit requirements: KTR10EZPF6652 (Rohm Semiconductor) includes High Voltage feature specification.

For packaging format requirements: Cut Tape format is available only in RC2012F6652CS (Samsung Electro-Mechanics). All other substitutes are supplied in Tape & Reel format.

Seated height variations (0.020" to 0.028") across all parts remain within standard PCB assembly tolerances and do not impact circuit functionality or board layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC2012F6652CS with ERJ-6ENF6652V in a non-automotive circuit?

A: Yes. Both components share identical electrical specifications (66.5 kΩ, ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C), package format (0805), and compliance ratings (ROHS3, MSL 1). The AEC-Q200 automotive certification on ERJ-6ENF6652V represents an additional qualification that does not restrict use in general industrial applications.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging supplies individual components on cut segments of carrier tape, suitable for manual assembly or small-volume production. Tape & Reel (TR) packaging supplies components on continuous reel format, optimized for automated pick-and-place assembly equipment. Electrical and mechanical specifications remain identical between packaging formats.

Q: Are all substitute parts compatible with automated assembly equipment?

A: Substitute parts supplied in Tape & Reel format (ERJ-6ENF6652V, KTR10EZPF6652, RC0805FR-0766K5L, RMCF0805FT66K5, CRCW080566K5FKEA) are compatible with standard automated pick-and-place systems. The original RC2012F6652CS in Cut Tape format requires manual handling or tape conversion for automated assembly.

Q: Does the seated height variation (0.020" to 0.028") affect PCB assembly?

A: No. All seated height values fall within standard PCB assembly process tolerances. Height variations do not impact solder joint formation, component placement accuracy, or circuit board clearance in standard 0805 package applications.

Q: Which substitute part has the highest inventory availability?

A: ERJ-6ENF6652V (Panasonic Electronic Components) has 52,384 pieces in stock, followed by CRCW080566K5FKEA (Vishay Dale) with 32,102 pieces and RMCF0805FT66K5 (Stackpole Electronics Inc) with 41,044 pieces.

Q: Can I use CRCW080566K5FKEA as a direct replacement for RC2012F6652CS?

A: Yes. CRCW080566K5FKEA meets all electrical and mechanical requirements for direct substitution. The 0.020" seated height is the lowest among all alternatives but remains within assembly process specifications.

Q: What does AEC-Q200 certification indicate?

A: AEC-Q200 is an automotive industry qualification standard confirming component reliability under automotive operating conditions. Components with this certification (ERJ-6ENF6652V, KTR10EZPF6652, RMCF0805FT66K5, CRCW080566K5FKEA) are suitable for both automotive and general industrial applications.
