Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F27R4CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 27.4 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package format: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

All identified substitute parts meet these mandatory parameters. Substitute parts are further categorized by additional certifications: direct equivalents maintain moisture-resistant features identical to the main part, while similar substitutes add automotive AEC-Q200 qualification, which represents an enhanced reliability standard applicable to automotive applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent: RC0805FR-0727R4L (YAGEO) functions as a direct equivalent to RC2012F27R4CS. Both components share identical electrical specifications, moisture-resistant thick film construction, and ROHS3 compliance. This substitute is appropriate for applications where the original Samsung component is unavailable and no automotive qualification is required.

Automotive-Qualified Substitutes: CRCW080527R4FKEA (Vishay Dale), ERJ-6ENF27R4V (Panasonic Electronic Components), and RMCF0805FT27R4 (Stackpole Electronics Inc) are functionally equivalent to the main part with the addition of AEC-Q200 automotive qualification. These components meet all electrical and mechanical parameters of the RC2012F27R4CS and are suitable for applications requiring automotive-grade reliability standards. Selection among these three automotive-qualified options depends on inventory availability and supply chain requirements.

All substitute parts maintain ROHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and active product status. Physical height variations among substitutes range from 0.020" to 0.028" seated maximum, all within typical PCB assembly tolerances for 0805 package components.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-0727R4L replace RC2012F27R4CS in any application? A: RC0805FR-0727R4L is electrically and mechanically equivalent to RC2012F27R4CS across all specified parameters. Substitution is valid for non-automotive applications. For automotive applications, AEC-Q200 qualified alternatives (CRCW080527R4FKEA, ERJ-6ENF27R4V, or RMCF0805FT27R4) are recommended.

Q: What is the difference between the main part and automotive-qualified substitutes? A: The main part RC2012F27R4CS does not carry AEC-Q200 automotive qualification. The substitutes CRCW080527R4FKEA, ERJ-6ENF27R4V, and RMCF0805FT27R4 include AEC-Q200 certification, indicating compliance with automotive reliability and quality standards. All other electrical and mechanical specifications remain identical.

Q: Are there physical size differences between these parts? A: All parts conform to 0805 (2012 Metric) package format with identical length (0.079") and width (0.049"). Seated height varies slightly: RC2012F27R4CS at 0.026", RC0805FR-0727R4L at 0.024", CRCW080527R4FKEA at 0.020", ERJ-6ENF27R4V at 0.028", and RMCF0805FT27R4 at 0.026". These variations are within standard PCB assembly tolerances.

Q: Do all substitute parts have the same moisture sensitivity rating? A: Yes. All parts listed, including the main part RC2012F27R4CS, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Which substitute should be selected for cost optimization? A: Selection criteria are based on product status, compliance certifications, and availability. RC0805FR-0727R4L offers direct equivalence without automotive qualification. CRCW080527R4FKEA, ERJ-6ENF27R4V, and RMCF0805FT27R4 provide automotive-qualified alternatives. Inventory levels and supply chain factors determine final selection.

Q: Are all parts ROHS3 compliant? A: Yes. RC2012F27R4CS and all listed substitutes are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements.
