RCS2012F5230CS Equivalent & Substitute Parts

Part Overview

The RCS2012F5230CS is a 523 Ohm ±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 RoHS3 compliance and unlimited moisture sensitivity level (MSL 1). The RCS2012F5230CS maintains active product status with 938 pieces currently in stock.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating), mechanical compatibility (package type and dimensions), and environmental operating parameters. Substitute components must maintain identical or compatible physical footprints and electrical performance characteristics to ensure direct board-level replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F5230CS are qualified based on the following critical parameters:

Electrical Equivalence: All substitute parts maintain identical resistance value (523 Ohms), tolerance (±1%), power rating (0.125W), and temperature coefficient (±100ppm/°C). These parameters ensure functional interchangeability in circuit applications.

Mechanical Compatibility: All substitute parts use the 0805 (2012 Metric) package with matching footprint dimensions (0.079" L × 0.049" W / 2.00mm × 1.25mm). Physical dimensions and termination count (2) are identical across all qualified substitutes.

Environmental Specifications: All substitute parts operate within the identical temperature range (-55°C to 155°C) and maintain RoHS3 compliance with MSL 1 rating. These specifications ensure compatibility with the same application environments and regulatory requirements.

Composition and Construction: All substitute parts utilize thick film construction technology, maintaining consistent performance characteristics and reliability profiles.

The four qualified substitute parts are grouped as direct equivalents based on these matching parameters. Additional features such as automotive AEC-Q200 certification or anti-sulfur construction represent enhanced capabilities that do not prevent substitution but may provide additional qualification for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts maintain active product status and full RoHS3 compliance, ensuring long-term availability and regulatory alignment with the original RCS2012F5230CS component.

CRCW0805523RFKEA (Vishay Dale): This substitute incorporates automotive AEC-Q200 qualification, providing enhanced reliability documentation for applications requiring automotive-grade component certification. The seated height of 0.020" (0.50mm) represents the lowest profile among all options, suitable for space-constrained PCB layouts.

ERJ-6ENF5230V (Panasonic Electronic Components): This substitute includes automotive AEC-Q200 certification and offers the highest inventory availability (34,983 pieces). The seated height of 0.028" (0.70mm) is the maximum among qualified substitutes and remains within standard PCB assembly tolerances.

RC0805FR-07523RL (YAGEO): This substitute features moisture-resistant construction matching the original part's environmental protection capabilities. With 69,218 pieces in inventory, this part offers the highest stock availability. The seated height of 0.024" (0.60mm) provides a mid-range profile option.

RMCF0805FT523R (Stackpole Electronics Inc): This substitute includes automotive AEC-Q200 qualification with a seated height of 0.026" (0.65mm), matching the original part's height specification. This option provides automotive-grade reliability with dimensional consistency to the RCS2012F5230CS.

All substitute parts are electrically and mechanically equivalent to the original component. Selection among substitutes depends on application-specific requirements regarding automotive qualification, inventory availability, or specific height constraints within the PCB assembly.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805523RFKEA replace RCS2012F5230CS in any application?

A: Yes. Both parts share identical electrical specifications (523 Ohms ±1%, 0.125W), operate across the same temperature range (-55°C to 155°C), and use the 0805 package format. The CRCW0805523RFKEA includes automotive AEC-Q200 certification, which represents an enhanced qualification level that does not prevent substitution in standard applications.

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

A: The seated height variations (0.020" to 0.028") reflect manufacturing tolerances within the 0805 package specification. All heights remain within standard PCB assembly clearance requirements. Height differences become relevant only in applications with extremely tight vertical space constraints or specific solder reflow profile requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All four substitute parts and the original RCS2012F5230CS maintain ROHS3 compliance. All parts also carry MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture-related handling restrictions during storage or assembly.

Q: Does the automotive AEC-Q200 certification on some substitutes affect compatibility?

A: No. AEC-Q200 certification represents an additional qualification standard that does not alter electrical or mechanical compatibility. Parts with AEC-Q200 certification can be used in non-automotive applications without compatibility issues. The certification indicates enhanced reliability documentation and testing, not a restriction on application scope.

Q: Can I mix different substitute parts within the same PCB assembly?

A: Yes. All substitute parts meet identical electrical and mechanical specifications for the 523 Ohm ±1% 0805 resistor function. Mixed sourcing from multiple manufacturers is technically compatible, though single-source procurement is typically preferred for supply chain consistency and traceability documentation.

Q: What is the difference between anti-sulfur and moisture-resistant construction?

A: Anti-sulfur construction (RCS2012F5230CS) provides protection against sulfur-containing atmospheric contaminants. Moisture-resistant construction (RC0805FR-07523RL) provides protection against humidity and moisture ingress. Both are environmental protection features that do not affect electrical equivalence. Selection depends on the specific environmental conditions of the application location.

Q: Are there any temperature coefficient differences among the parts?

A: No. All parts, including the original and all four substitutes, maintain identical temperature coefficient specifications of ±100ppm/°C across the -55°C to 155°C operating range.
