Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC2012F6651CS are qualified based on the following criteria:

Electrical Parameters (Critical):

• Resistance value: 6.65 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Critical):

• 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
• REACH Unaffected status

All identified substitute parts match these core parameters. Variations in seated height (0.020" to 0.028") remain within acceptable PCB assembly tolerances for 0805 components. Automotive AEC-Q200 certification on certain substitutes represents an enhanced qualification level and does not restrict their use in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are Active product status components with full ROHS3 compliance and MSL Level 1 rating, confirming their suitability for direct replacement of the RC2012F6651CS in circuit applications.

For General Industrial Applications: RC0805FR-076K65L (YAGEO) and RC2012F6651CS (Samsung Electro-Mechanics) both feature moisture-resistant construction and are appropriate for standard commercial environments.

For Automotive and High-Reliability Applications: ERJ-6ENF6651V (Panasonic), KTR10EZPF6651 (Rohm), RMCF0805FT6K65 (Stackpole), and CRCW08056K65FKEA (Vishay Dale) carry AEC-Q200 automotive qualification, indicating enhanced screening and reliability validation. KTR10EZPF6651 additionally features high voltage capability.

For Space-Constrained PCB Designs: CRCW08056K65FKEA (Vishay Dale) offers the lowest seated height at 0.020", beneficial for applications with minimal vertical clearance requirements.

All parts maintain identical electrical performance across the specified operating temperature range and are compatible with standard 0805 SMD assembly processes.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC2012F6651CS with any of these parts without circuit redesign?

A: Yes. All listed parts match the critical electrical parameters (6.65 kΩ ±1%, 0.125W, ±100ppm/°C) and mechanical specifications (0805 package, 2.00mm x 1.25mm). They are direct functional equivalents. Seated height variations (0.020" to 0.028") are within standard PCB assembly tolerances for 0805 components.

Q: What is the difference between parts with "Moisture Resistant" and "Automotive AEC-Q200" features?

A: Moisture Resistant indicates enhanced protection against humidity ingress. Automotive AEC-Q200 indicates the part has undergone automotive-grade qualification testing including thermal cycling, humidity bias, and mechanical stress screening. AEC-Q200 parts are suitable for both automotive and general industrial use. Moisture Resistant parts are optimized for commercial and industrial environments.

Q: Are AEC-Q200 qualified parts suitable for non-automotive applications?

A: Yes. AEC-Q200 qualification represents an enhanced reliability standard and does not restrict use in non-automotive circuits. These parts are fully compatible with general industrial, commercial, and consumer applications.

Q: Does the seated height difference affect PCB assembly compatibility?

A: No. The seated height range of 0.020" to 0.028" (0.50mm to 0.70mm) is within standard PCB assembly process windows for 0805 components. All parts are compatible with standard reflow soldering and automated assembly equipment.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed parts, including the main part RC2012F6651CS, are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating, confirming compliance with environmental and reliability standards.

Q: Which substitute part offers the best availability?

A: RMCF0805FT6K65 (Stackpole Electronics Inc) shows the highest inventory level at 154,887 pieces. CRCW08056K65FKEA (Vishay Dale) and RC0805FR-076K65L (YAGEO) also maintain substantial stock levels above 35,000 pieces.
