RCS2012F2431CS Equivalent & Substitute Parts Reference

Part Overview

The RCS2012F2431CS is a 2.43 kOhms ±1% 0.125W chip resistor manufactured by Samsung Electro-Mechanics in the 0805 (2012 Metric) package. This thick film resistor features anti-sulfur and moisture-resistant properties with an operating temperature range of -55°C to 155°C. The part is Active status and ROHS3 compliant. Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing, inventory optimization, or manufacturer-specific certifications such as automotive AEC-Q200 qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F2431CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 2.43 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these mandatory parameters. Variations in physical height (seated maximum) and packaging format (Tape & Reel versus Cut Tape) do not affect electrical substitutability but may impact assembly and procurement workflows.

Parameter Comparison

Engineering Selection Recommendations

CRCW08052K43FKEA (Vishay Dale): This substitute carries AEC-Q200 automotive qualification and is suitable for applications requiring automotive-grade reliability. The seated height of 0.020" (0.50mm) is the lowest among all options, providing design flexibility for space-constrained layouts. Tape & Reel packaging supports high-volume production workflows.

ERJ-6ENF2431V (Panasonic Electronic Components): This substitute includes AEC-Q200 automotive qualification and offers the highest inventory availability (82,816 pcs). The seated height of 0.028" (0.70mm) is the maximum among all options and must be verified against PCB clearance requirements. Tape & Reel packaging is standard for automated assembly.

RC0805FR-072K43L (YAGEO): This substitute features moisture-resistant properties matching the original part specification. It is available in Cut Tape (CT) & Digi-Reel® packaging, which differs from standard Tape & Reel format and may require alternative handling procedures. The seated height of 0.024" (0.60mm) provides mid-range clearance characteristics. No automotive certification is specified.

RMCF0805FT2K43 (Stackpole Electronics Inc): This substitute carries AEC-Q200 automotive qualification and offers seated height of 0.026" (0.65mm), closely matching the original part. Tape & Reel packaging supports standard production processes. Inventory availability is 30,915 pcs.

All substitute parts maintain full electrical equivalence to the RCS2012F2431CS across resistance, tolerance, power rating, temperature coefficient, and operating temperature range. Selection among substitutes depends on specific application requirements including automotive certification needs, physical height constraints, and packaging format compatibility.

Frequently Asked Questions (FAQ)

Q: Can CRCW08052K43FKEA replace RCS2012F2431CS in non-automotive applications?

A: Yes. The CRCW08052K43FKEA meets all electrical and mechanical parameters required for direct substitution. AEC-Q200 certification is an additional qualification that does not restrict use in non-automotive circuits. The lower seated height (0.020" vs 0.026") may provide design advantages in space-constrained layouts.

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

A: Seated height affects PCB clearance and component placement during assembly. The RCS2012F2431CS has a maximum seated height of 0.026" (0.66mm). Substitutes range from 0.020" to 0.028". Verify that selected substitute height does not exceed PCB design clearance specifications. Lower heights provide additional margin; higher heights require confirmation of available clearance.

Q: Why does RC0805FR-072K43L use Cut Tape (CT) & Digi-Reel® packaging instead of standard Tape & Reel?

A: Packaging format is a procurement and assembly consideration, not an electrical parameter. Cut Tape & Digi-Reel® packaging is suitable for lower-volume or mixed-component orders. Standard Tape & Reel packaging (used by other substitutes) is optimized for high-volume automated assembly. Confirm that your assembly equipment supports the selected packaging format.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitutes (CRCW08052K43FKEA, ERJ-6ENF2431V, RC0805FR-072K43L, RMCF0805FT2K43) are ROHS3 compliant, matching the original RCS2012F2431CS specification.

Q: Which substitute offers the best inventory availability?

A: ERJ-6ENF2431V (Panasonic) has the highest inventory level at 82,816 pcs. RMCF0805FT2K43 (Stackpole) has 30,915 pcs, and RC0805FR-072K43L (YAGEO) has 27,184 pcs. CRCW08052K43FKEA (Vishay Dale) has 20,631 pcs. Inventory levels are subject to change and should be confirmed with suppliers.

Q: Do automotive-rated substitutes (AEC-Q200) cost more than non-automotive options?

A: Cost comparison is not provided in this reference. Contact suppliers directly for pricing information. AEC-Q200 certification indicates compliance with automotive reliability standards but does not inherently determine cost relative to non-certified alternatives.

Q: Can I mix different substitute parts in the same circuit board design?

A: Yes. All substitutes are electrically equivalent and mechanically compatible within the 0805 package footprint. However, verify that seated height variations do not create assembly or clearance conflicts. Mixing manufacturers may introduce minor variations in delivery schedules and quality documentation.
