Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F2431CS is determined by strict alignment of the following critical parameters:

Electrical Specifications: Resistance value (2.43 kOhms), tolerance (±1%), and power rating (0.125W) must be identical across all substitute parts.

Package Compatibility: All substitute parts must use the 0805 (2012 Metric) package format with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm).

Environmental & Compliance Requirements: Operating temperature range (-55°C ~ 155°C), temperature coefficient (±100ppm/°C), Moisture Sensitivity Level (MSL 1), RoHS3 compliance, and REACH unaffected status must be maintained.

Composition & Construction: Thick film construction is required for all substitutes.

The identified substitute parts meet all these criteria and are grouped as direct equivalents. Variations in packaging format (Tape & Reel vs. Cut Tape), manufacturer series designation, and optional automotive qualification (AEC-Q200) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain full electrical and mechanical compatibility with the RC2012F2431CS. Selection among these equivalents should be based on the following factors:

Packaging Format: The RC2012F2431CS is supplied in Tape & Reel (TR) format. The RC0805FR-072K43L (YAGEO) is available in Cut Tape (CT) & Digi-Reel® format, which may affect procurement and assembly processes. The remaining substitutes (CRCW08052K43FKEA, ERJ-6ENF2431V, RMCF0805FT2K43) are supplied in Tape & Reel format, matching the original packaging.

Automotive Qualification: The CRCW08052K43FKEA (Vishay Dale), ERJ-6ENF2431V (Panasonic), and RMCF0805FT2K43 (Stackpole) carry AEC-Q200 automotive qualification. The RC2012F2431CS and RC0805FR-072K43L do not specify this rating. For non-automotive applications, all parts are functionally equivalent. For automotive designs, the AEC-Q200 qualified parts provide additional reliability assurance.

Inventory Availability: All substitute parts are in active production with substantial stock levels. Selection may be influenced by supply chain logistics and lead time requirements.

Physical Height Variation: Seated height ranges from 0.020" (0.50mm) to 0.028" (0.70mm). For applications with tight vertical clearance constraints, the CRCW08052K43FKEA offers the lowest profile at 0.020" (0.50mm).

All parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment across industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-072K43L (YAGEO) be used as a direct replacement for RC2012F2431CS (Samsung)?

A: Yes. The RC0805FR-072K43L meets all electrical and mechanical specifications of the RC2012F2431CS. Both components share identical resistance (2.43 kOhms), tolerance (±1%), power rating (0.125W), package format (0805), composition (thick film), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and compliance certifications (ROHS3, REACH unaffected). The primary difference is packaging format: RC0805FR-072K43L is supplied in Cut Tape & Digi-Reel format versus Tape & Reel for the original part.

Q: What is the significance of AEC-Q200 qualification on CRCW08052K43FKEA, ERJ-6ENF2431V, and RMCF0805FT2K43?

A: AEC-Q200 is an automotive industry qualification standard that certifies component reliability under automotive operating conditions. Parts carrying this rating have undergone additional testing and validation. For non-automotive applications, AEC-Q200 qualification provides no functional advantage. For automotive designs, these qualified parts offer enhanced reliability assurance and may be required by design specifications or procurement standards.

Q: Are there physical dimension differences that affect PCB layout?

A: All substitute parts use the identical 0805 (2012 Metric) package with footprint dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm). Seated height varies between 0.020" (0.50mm) and 0.028" (0.70mm). For standard PCB applications with typical vertical clearance, this variation is negligible. For designs with constrained vertical space, the CRCW08052K43FKEA (0.020" maximum height) offers the lowest profile option.

Q: Do all substitute parts maintain the same moisture sensitivity level?

A: Yes. All substitute parts, including the original RC2012F2431CS, carry Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements. This ensures consistent handling and storage procedures across all equivalent parts.

Q: Which substitute part offers the best inventory availability?

A: The ERJ-6ENF2431V (Panasonic) has the highest reported inventory at 82,816 pieces in stock. The RC0805FR-072K43L (YAGEO) follows with 27,184 pieces. All substitute parts maintain active production status with substantial availability for standard procurement timelines.

Q: Can packaging format differences affect assembly compatibility?

A: Packaging format (Tape & Reel versus Cut Tape & Digi-Reel) affects procurement and handling but does not impact electrical or mechanical assembly compatibility. The RC0805FR-072K43L in Cut Tape format may require different feeder equipment on automated assembly lines compared to standard Tape & Reel components. Verify compatibility with your assembly equipment specifications before procurement.
