Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC2012F3924CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 3.92 MOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 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 meet these core requirements. Variations in seated height and specific feature sets (moisture resistance vs. automotive AEC-Q200 qualification) do not affect functional substitution within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

RC0805FR-073M92L (YAGEO): This part is a direct functional equivalent to the RC2012F3924CS. Both components share identical electrical specifications, package dimensions, and compliance certifications. The YAGEO substitute exhibits a lower seated height (0.024" vs. 0.026"), which presents no compatibility issues for standard PCB assembly processes. This part is suitable for direct substitution in applications where moisture resistance is the primary feature requirement.

CRCW08053M92FKEA (Vishay Dale): This part meets all core electrical and mechanical substitution criteria. The primary distinction is the inclusion of AEC-Q200 automotive qualification, which provides additional reliability assurance for automotive-grade applications. The seated height is further reduced to 0.020", maintaining full compatibility with 0805 package specifications. This part is suitable for substitution in both general-purpose and automotive-qualified designs.

All three parts maintain Active product status, ensuring long-term availability and supply chain stability. Selection between alternatives should be based on specific application requirements, existing supplier relationships, and inventory availability rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-073M92L replace RC2012F3924CS in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical resistance values (3.92 MOhms), tolerance (±1%), power rating (0.125W), package type (0805), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). The minor difference in seated height (0.024" vs. 0.026") does not affect PCB assembly or circuit performance.

Q: What is the difference between the Samsung and YAGEO versions?

A: The RC2012F3924CS (Samsung) and RC0805FR-073M92L (YAGEO) are functionally identical. Both feature moisture-resistant thick film construction, unlimited moisture sensitivity rating (MSL 1), and RoHS3 compliance. The only measurable difference is seated height, which is within standard 0805 package tolerances.

Q: Why does the Vishay Dale part have AEC-Q200 qualification?

A: The CRCW08053M92FKEA includes AEC-Q200 automotive qualification, indicating it meets automotive industry reliability and testing standards. This qualification is optional for general-purpose applications but required for automotive-grade circuit designs. The electrical and mechanical performance remains identical to non-automotive versions.

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

A: Yes. All three parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. This packaging format is standard for 0805 surface mount resistors.

Q: Do seated height differences affect PCB assembly?

A: No. The seated height variations (0.026", 0.024", and 0.020") are all within the 0805 (2012 Metric) package specification tolerance. These differences do not impact reflow soldering, component placement accuracy, or final circuit performance.

Q: Are all parts RoHS3 compliant?

A: Yes. All three substitute parts carry RoHS3 compliance certification and REACH Unaffected status, meeting current environmental and regulatory requirements for electronic components.

Q: Can these parts be used interchangeably in the same PCB design?

A: Yes. All three parts are mechanically and electrically interchangeable. PCB designs do not require modification to accommodate any of these substitutes. Component selection can be based on availability, cost, and supplier preference.
