Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC2012F2434CS are qualified based on strict alignment of the following parameters:

Electrical Parameters (Critical):

• Resistance value: 2.43 MOhms
• 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)
• Composition: Thick Film
• Number of terminations: 2

Compliance Parameters:

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

All identified substitutes meet these criteria without exception. Packaging format (Tape & Reel or Cut Tape) does not affect electrical or mechanical compatibility and represents a procurement variable only.

Parameter Comparison

Engineering Selection Recommendations

RC0805FR-072M43L (YAGEO): This substitute maintains identical electrical specifications and compliance certifications to the original RC2012F2434CS. Both components are ROHS3 Compliant with REACH Unaffected status and MSL Level 1. The seated height differential (0.024" vs 0.026") is within typical PCB assembly tolerances for 0805 packages. Tape & Reel packaging matches the original format. This part is suitable for direct substitution in applications where the original Samsung component is unavailable.

CRCW08052M43FKEA (Vishay Dale): This substitute meets all critical electrical and mechanical parameters with ROHS3 Compliant and REACH Unaffected certifications. The component includes AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components. The seated height (0.020") is lower than the original, which may be advantageous in space-constrained designs. Cut Tape packaging differs from the original Tape & Reel format but does not affect component functionality. This part is suitable for substitution in both general-purpose and automotive applications.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-072M43L and CRCW08052M43FKEA be used interchangeably with RC2012F2434CS?

A: Yes. Both substitutes match the critical electrical parameters (2.43 MOhms, ±1%, 0.125W), temperature specifications (-55°C ~ 155°C, ±100ppm/°C), package format (0805 / 2012 Metric), and compliance requirements (ROHS3, REACH Unaffected). Mechanical compatibility is confirmed through identical length and width dimensions (0.079" x 0.049").

Q: What is the significance of the height difference between these parts?

A: The seated height variations (0.026" for Samsung, 0.024" for YAGEO, 0.020" for Vishay) reflect manufacturing tolerances within the 0805 package specification. These differences do not affect electrical performance or PCB assembly compatibility for standard reflow soldering processes.

Q: Does packaging format (Tape & Reel vs Cut Tape) affect component selection?

A: Packaging format is a procurement and handling variable only. It does not affect electrical performance, mechanical fit, or functional compatibility. Selection between Tape & Reel and Cut Tape depends on assembly line equipment and inventory management requirements.

Q: Are there any compliance differences between the three parts?

A: All three parts are ROHS3 Compliant and REACH Unaffected. The Vishay Dale CRCW08052M43FKEA includes AEC-Q200 automotive qualification, which is an additional certification not present in the Samsung or YAGEO parts. This qualification is beneficial for automotive applications but does not restrict use in general-purpose applications.

Q: What inventory considerations apply to these substitutes?

A: Current inventory levels are 1137 units (Samsung), 14566 units (YAGEO), and 35693 units (Vishay). Higher inventory availability for substitute parts may provide supply chain advantages for high-volume procurement or extended lead-time mitigation.
