RC2012F2R4CS Equivalent & Substitute Parts

Part Overview

The RC2012F2R4CS is a 2.4 Ohms ±1% 0.125W chip resistor manufactured by Samsung Electro-Mechanics in the 0805 (2012 Metric) package. This thick film resistor features moisture resistance and operates across the temperature range of -55°C to 155°C. The component is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications are available from alternative manufacturers, enabling procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F2R4CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (2.4 Ohms), tolerance (±1%), and power rating (0.125W) must be identical.

Mechanical Compatibility: Package type (0805/2012 Metric), physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm), and seated height (0.026" / 0.65mm maximum) must match exactly to ensure PCB footprint compatibility.

Environmental & Compliance Requirements: Operating temperature range (-55°C to 155°C), RoHS3 compliance, and MSL rating (1 - Unlimited) must be maintained or exceeded.

Composition & Construction: Thick film construction is required for functional equivalence.

The RMCF0805FT2R40 from Stackpole Electronics Inc meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the RC2012F2R4CS and RMCF0805FT2R40 are active production components with ROHS3 compliance and identical electrical and mechanical specifications. The RMCF0805FT2R40 carries AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components. The temperature coefficient of the Stackpole part (±200ppm/°C) is superior to the Samsung part (±300ppm/°C), indicating tighter temperature stability. Selection between these parts should be based on application requirements, supply availability, and any specific automotive or reliability certifications mandated by the end application.

Frequently Asked Questions (FAQ)

Q: Can the RMCF0805FT2R40 be used as a direct replacement for the RC2012F2R4CS?

A: Yes. Both parts share identical resistance (2.4 Ohms), tolerance (±1%), power rating (0.125W), package dimensions (0805/2012 Metric), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, MSL 1). Physical footprint compatibility is guaranteed.

Q: What is the difference in temperature coefficient between these parts?

A: The RC2012F2R4CS has a temperature coefficient of ±300ppm/°C, while the RMCF0805FT2R40 has ±200ppm/°C. The Stackpole part exhibits superior temperature stability. For applications with tight tolerance requirements across temperature ranges, the lower coefficient may be advantageous.

Q: Does the AEC-Q200 rating on the Stackpole part affect compatibility?

A: No. AEC-Q200 is an automotive qualification standard that indicates additional reliability testing and quality assurance. It does not affect electrical or mechanical compatibility. The part remains suitable for non-automotive applications.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.079" L x 0.049" W (2.00mm x 1.25mm) with a maximum seated height of 0.026" (0.65mm). PCB footprints are identical.

Q: What is the moisture sensitivity level for both parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are both parts RoHS compliant?

A: Yes. Both the RC2012F2R4CS and RMCF0805FT2R40 are ROHS3 compliant.
