RCS2012F61R9CS Equivalent & Substitute Parts

Part Overview

The RCS2012F61R9CS is a 61.9 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.125W (1/8W) in 0805 (2012 Metric) package format. This component features anti-sulfur and moisture-resistant construction with unlimited moisture sensitivity level (MSL 1). The part is currently in active production status and ROHS3 compliant. Equivalent and substitute parts are identified when identical electrical specifications and mechanical compatibility are maintained across different manufacturers while preserving the same package footprint and performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution validity for the RCS2012F61R9CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (61.9 Ohms), tolerance (±1%), power rating (0.125W), and temperature coefficient (±100ppm/°C) must be identical.

Mechanical Compatibility: Package format (0805 / 2012 Metric), physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm), and number of terminations (2) must match.

Environmental & Compliance: Operating temperature range (-55°C ~ 155°C), RoHS3 compliance, MSL rating (1), and REACH status must be equivalent or superior.

Composition: Thick film construction is maintained across all substitute parts.

All four substitute parts listed meet these criteria and are therefore direct functional equivalents suitable for board-level replacement without design modification.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active production status and ROHS3 compliance equivalent to the RCS2012F61R9CS. Selection between equivalent parts is based on application-specific requirements and supply chain considerations:

For General Industrial Applications: RC0805FR-0761R9L (YAGEO) and RCS2012F61R9CS (Samsung Electro-Mechanics) are suitable. Both feature moisture-resistant construction with standard MSL 1 rating.

For Automotive Applications: CRCW080561R9FKEA (Vishay Dale), ERJ-6ENF61R9V (Panasonic Electronic Components), and RMCF0805FT61R9 (Stackpole Electronics Inc) carry AEC-Q200 automotive qualification and are appropriate for automotive-grade circuit designs.

For Height-Constrained PCB Layouts: CRCW080561R9FKEA (0.50mm maximum seated height) offers the lowest profile option. ERJ-6ENF61R9V (0.70mm) presents the highest profile among substitutes.

All parts are REACH unaffected and classified under ECCN EAR99 with identical HTSUS code 8533.21.0030.

Frequently Asked Questions (FAQ)

Q: Can CRCW080561R9FKEA replace RCS2012F61R9CS in non-automotive applications?

A: Yes. CRCW080561R9FKEA meets all electrical and mechanical specifications required for direct substitution. AEC-Q200 automotive qualification does not restrict use in general industrial applications. The part is ROHS3 compliant and maintains identical resistance, tolerance, power rating, and operating temperature range.

Q: What is the significance of the height difference between substitute parts?

A: Height variation (0.50mm to 0.70mm maximum seated height) affects PCB assembly clearance and solder joint profile. For standard applications without height constraints, all parts are interchangeable. For space-constrained designs, verify clearance requirements against the specific substitute part's maximum height specification.

Q: Are all substitute parts suitable for high-temperature applications?

A: Yes. All substitute parts and the main part RCS2012F61R9CS operate across the identical temperature range of -55°C to 155°C with ±100ppm/°C temperature coefficient. No thermal performance differentiation exists between the main part and substitutes.

Q: What is the difference between anti-sulfur and automotive AEC-Q200 features?

A: Anti-sulfur construction (RCS2012F61R9CS, RC0805FR-0761R9L) provides protection against sulfur-containing environmental contaminants. AEC-Q200 qualification (CRCW080561R9FKEA, ERJ-6ENF61R9V, RMCF0805FT61R9) indicates automotive-grade reliability testing and qualification. These are distinct feature sets; AEC-Q200 parts do not inherently include anti-sulfur treatment, and anti-sulfur parts are not automotive-qualified unless explicitly stated.

Q: Is package footprint identical across all parts?

A: Yes. All parts use 0805 (2012 Metric) package with identical land pattern dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm). PCB footprint design requires no modification when substituting between any of these parts.

Q: Can these parts be used interchangeably in existing designs without re-qualification?

A: Electrical and mechanical interchangeability is confirmed. Design re-qualification depends on application-specific requirements, supply chain policies, and quality assurance procedures. Consult design documentation and quality standards applicable to your application.
