RCS2012F4872CS Equivalent & Substitute Parts Reference

Part Overview

The RCS2012F4872CS is a 48.7 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 0805 (2012 Metric) package format. This component is rated for 0.125W (1/8W) power dissipation and operates across the temperature range of -55°C to 155°C. The part features anti-sulfur and moisture-resistant construction with a temperature coefficient of ±100ppm/°C. Currently in active production status with 1005 pieces available in inventory, this resistor is ROHS3 compliant and MSL 1 rated. Equivalent and substitute parts are identified based on matching electrical specifications, mechanical dimensions, and environmental compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F4872CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value of 48.7 kOhms, tolerance of ±1%, and power rating of 0.125W (1/8W) must be identical. Temperature coefficient of ±100ppm/°C and operating temperature range of -55°C to 155°C establish the thermal performance envelope.

Mechanical Compatibility: Package designation of 0805 (2012 Metric) with physical dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) ensures PCB footprint compatibility. Height variations within the seated maximum specification do not affect substitutability.

Environmental & Compliance Requirements: ROHS3 compliance, MSL 1 rating, and REACH unaffected status are mandatory for all substitutes. Composition must be thick film construction.

All identified substitute parts meet these criteria without exception. Variations in specific features (such as automotive AEC-Q200 certification or anti-sulfur treatment) represent enhancements rather than deviations from the core substitution parameters.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed—RCS2012F4872CS (Samsung Electro-Mechanics), CRCW080548K7FKEA (Vishay Dale), ERJ-6ENF4872V (Panasonic Electronic Components), and RC0805FR-0748K7L (YAGEO)—are active production components with full ROHS3 compliance and REACH unaffected status. Each part satisfies the core electrical and mechanical requirements for direct substitution in 48.7 kOhms ±1% 0.125W 0805 applications.

The Vishay Dale CRCW080548K7FKEA and Panasonic ERJ-6ENF4872V variants include automotive AEC-Q200 certification, which provides additional qualification for automotive-grade applications. The Samsung RCS2012F4872CS and YAGEO RC0805FR-0748K7L feature moisture-resistant construction. Selection between these options depends on application-specific requirements for automotive qualification or enhanced environmental protection, not on substitution compatibility.

Inventory availability varies across manufacturers: YAGEO RC0805FR-0748K7L (42,993 pcs), Panasonic ERJ-6ENF4872V (30,864 pcs), Vishay Dale CRCW080548K7FKEA (22,849 pcs), and Samsung RCS2012F4872CS (1,005 pcs).

Frequently Asked Questions (FAQ)

Q: Can CRCW080548K7FKEA replace RCS2012F4872CS in any application?

A: Yes. Both parts share identical electrical specifications (48.7 kOhms ±1%, 0.125W), thermal characteristics (±100ppm/°C, -55°C to 155°C), mechanical dimensions (0805 package, 2.00mm x 1.25mm), and compliance status (ROHS3, MSL 1, REACH unaffected). The CRCW080548K7FKEA includes automotive AEC-Q200 certification, which does not restrict its use in non-automotive applications.

Q: What is the difference between the Samsung and YAGEO versions?

A: The RCS2012F4872CS (Samsung) features anti-sulfur and moisture-resistant construction with a maximum seated height of 0.026" (0.66mm). The RC0805FR-0748K7L (YAGEO) features moisture-resistant construction with a maximum seated height of 0.024" (0.60mm). Both meet identical electrical and thermal specifications. The height difference does not affect PCB compatibility for standard 0805 footprints.

Q: Are the Panasonic and Vishay parts suitable for automotive applications?

A: Both the Panasonic ERJ-6ENF4872V and Vishay Dale CRCW080548K7FKEA carry AEC-Q200 automotive qualification. This certification indicates compliance with automotive reliability and performance standards. The Samsung and YAGEO parts do not carry this specific certification but remain fully functional in automotive circuits where AEC-Q200 qualification is not a design requirement.

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

A: Yes. All four parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All parts conform to the 0805 (2012 Metric) package standard with identical footprint dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm). Seated height variations (0.020" to 0.028") fall within standard PCB assembly tolerances and do not affect interchangeability.

Q: What compliance certifications apply to all substitute parts?

A: All parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 ratings. ECCN classification is EAR99 for all variants, and HTSUS code is 8533.21.0030 for all parts.
