Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F6652CS are qualified based on the following critical parameters that determine functional interchangeability:

Electrical Parameters:

• 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:

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

Compliance Parameters:

• RoHS3 compliance
• Moisture Sensitivity Level 1 (Unlimited)
• REACH Unaffected status

All identified substitute parts match these core parameters. Variations in packaging format (Tape & Reel versus Cut Tape), seated height tolerances, and optional automotive certifications (AEC-Q200) do not affect electrical or mechanical interchangeability for standard applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain identical electrical specifications and mechanical compatibility with the RCS2012F6652CS. Selection among these alternatives is determined by application-specific requirements and supply chain considerations:

RC2012F6652CS (Samsung Electro-Mechanics): Identical electrical performance to the main part with Cut Tape packaging. Suitable for applications requiring smaller order quantities or manual assembly processes.

CRCW080566K5FKEA (Vishay Dale): Automotive AEC-Q200 rated. Lowest seated height (0.50mm) provides advantage in space-constrained PCB layouts. Highest inventory availability (32,102 pcs). Recommended for automotive applications or designs requiring enhanced reliability qualification.

ERJ-6ENF6652V (Panasonic Electronic Components): Automotive AEC-Q200 rated with highest inventory availability (52,384 pcs). Seated height of 0.70mm is within acceptable tolerance for standard PCB designs. Suitable for automotive and industrial applications.

RC0805FR-0766K5L (YAGEO): Standard industrial-grade thick film resistor with moderate inventory (5,655 pcs). Seated height of 0.60mm provides balanced profile for general applications.

RMCF0805FT66K5 (Stackpole Electronics Inc): Automotive AEC-Q200 rated with substantial inventory (41,044 pcs). Seated height of 0.65mm matches the original part specification. Recommended for automotive and high-reliability applications.

All parts comply with ROHS3 and maintain MSL 1 rating, ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can RC2012F6652CS replace RCS2012F6652CS directly?

A: Yes. Both parts are manufactured by Samsung Electro-Mechanics with identical electrical specifications (66.5 kΩ ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C). The primary difference is packaging format: RCS2012F6652CS is supplied in Tape & Reel while RC2012F6652CS is supplied in Cut Tape. Electrical and mechanical interchangeability is complete.

Q: What is the significance of AEC-Q200 certification on substitute parts?

A: AEC-Q200 is an automotive industry qualification standard indicating enhanced reliability testing and quality assurance. Parts bearing this certification (CRCW080566K5FKEA, ERJ-6ENF6652V, RMCF0805FT66K5) are suitable for automotive applications and high-reliability environments. Non-AEC-Q200 parts (RC2012F6652CS, RC0805FR-0766K5L) are suitable for standard industrial and consumer applications.

Q: Do seated height variations affect PCB assembly compatibility?

A: Seated height variations (0.50mm to 0.70mm) are within standard 0805 package tolerances and do not affect PCB assembly compatibility. All parts are mechanically interchangeable on standard 0805 footprints. Height differences may be relevant only in extremely space-constrained designs with specific clearance requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original RCS2012F6652CS specifications. This ensures compatibility with modern manufacturing processes and environmental regulations.

Q: What packaging considerations apply when selecting substitutes?

A: RCS2012F6652CS and all substitute parts except RC2012F6652CS are supplied in Tape & Reel format suitable for automated assembly. RC2012F6652CS is supplied in Cut Tape format, appropriate for manual assembly or small-volume production. Selection depends on manufacturing process requirements and order quantity.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. All substitute parts match the core electrical parameters (66.5 kΩ ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C) and mechanical specifications (0805 package, 2.00mm x 1.25mm dimensions, 2 terminations). Direct substitution is supported without circuit redesign or re-qualification.
