Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC2012F7681CS are classified based on strict electrical and mechanical equivalence. All substitute candidates must satisfy the following criteria:

Electrical Equivalence Requirements:

• Resistance value: 7.68 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Equivalence Requirements:

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

Compliance Requirements:

• RoHS3 compliance
• MSL 1 (Unlimited) rating
• REACH Unaffected status

All identified substitute parts meet these core parameters. Additional features such as automotive AEC-Q200 certification or moisture-resistant construction represent enhanced specifications beyond the base requirements and are noted separately.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts satisfy the core electrical and mechanical requirements for direct replacement of the RC2012F7681CS. Selection among these alternatives is determined by application-specific requirements and compliance certifications.

For General Industrial Applications: RC0805FR-077K68L (YAGEO) provides moisture-resistant construction equivalent to the original part with reduced maximum height (0.60mm vs 0.65mm), offering improved PCB density without compromising electrical performance.

For Automotive Applications: ERJ-6ENF7681V (Panasonic), RMCF0805FT7K68 (Stackpole), AC0805FR-077K68L (YAGEO), and CRCW08057K68FKEA (Vishay Dale) all carry AEC-Q200 automotive qualification. AC0805FR-077K68L combines automotive certification with moisture-resistant construction. CRCW08057K68FKEA offers the lowest profile height (0.50mm) for space-constrained automotive designs.

For Moisture-Sensitive Environments: RC0805FR-077K68L and AC0805FR-077K68L both feature moisture-resistant construction. AC0805FR-077K68L additionally provides automotive-grade reliability.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and REACH Unaffected status, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6ENF7681V replace RC2012F7681CS in non-automotive applications?

A: Yes. ERJ-6ENF7681V meets all electrical and mechanical specifications required for direct substitution. The AEC-Q200 automotive qualification represents an enhanced specification that does not restrict use in general industrial applications. All core parameters including resistance, tolerance, power rating, temperature range, and package dimensions are identical.

Q: What is the significance of the height differences among substitute parts?

A: Height variations (0.50mm to 0.70mm) reflect manufacturing tolerances and design differences among manufacturers. All parts remain within the 0805 package specification. Height differences are relevant only for applications with strict PCB clearance constraints or automated assembly processes with height-sensitive placement equipment. For standard applications, height variations are not functionally significant.

Q: Are moisture-resistant variants required for all applications?

A: Moisture-resistant construction is application-dependent. RC0805FR-077K68L and AC0805FR-077K68L include this feature. For applications exposed to high humidity, condensation, or moisture-prone environments, moisture-resistant variants are recommended. For standard indoor industrial or consumer applications, non-moisture-resistant alternatives are functionally equivalent.

Q: What does AEC-Q200 certification mean for non-automotive use?

A: AEC-Q200 is an automotive industry qualification standard indicating enhanced reliability testing and quality assurance. Parts carrying this certification exceed standard industrial requirements. In non-automotive applications, AEC-Q200 certified parts provide equivalent or superior performance compared to non-certified alternatives, with no disadvantages or incompatibilities.

Q: Are all substitute parts available in the same packaging formats?

A: Packaging formats differ. RC2012F7681CS and most substitutes are supplied in Tape & Reel (TR) format. RC0805FR-077K68L is available in Cut Tape (CT) & Digi-Reel® format. Packaging format affects procurement and automated assembly compatibility but does not impact electrical or mechanical performance. Verify packaging compatibility with your procurement and assembly processes.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes, all substitute parts are mechanically and electrically interchangeable on the PCB. Identical package dimensions, termination count, and electrical specifications ensure direct substitution. Height variations do not prevent interchangeability in standard applications. Verify that your assembly process and equipment accommodate the specific height of the selected part.
