RCS2012F1651CS Equivalent & Substitute Parts

Part Overview

The RCS2012F1651CS is a 1.65 kOhms ±1% 0.125W thick film chip resistor in 0805 (2012 Metric) package manufactured by Samsung Electro-Mechanics. This component is classified as Active product status with anti-sulfur and moisture-resistant properties. The part is ROHS3 compliant and carries MSL Level 1 (Unlimited) moisture sensitivity rating.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package form factor and performance envelope. Alternative sources provide equivalent functionality for applications requiring component availability, supply chain diversification, or specific certification requirements such as automotive AEC-Q200 qualification.

Key Parameters

Substitute Part Grouping Explanation

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

Electrical Equivalence Requirements:

• Resistance value: 1.65 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Equivalence Requirements:

• Package form factor: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2
• Supplier device package: 0805

Compliance Requirements:

• RoHS3 compliance
• MSL Level 1 (Unlimited)
• REACH Unaffected status
• ECCN: EAR99

All identified substitute parts meet these criteria. Variations in height (seated maximum) and specific feature sets (anti-sulfur vs. automotive AEC-Q200 qualification) do not affect functional substitution within the specified electrical and mechanical envelope.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are Active product status components with full ROHS3 compliance and MSL Level 1 rating, establishing functional equivalence with the RCS2012F1651CS.

CRCW08051K65FKEA (Vishay Dale): Carries automotive AEC-Q200 qualification. Lowest seated height (0.020" / 0.50mm) provides design margin for space-constrained applications. Suitable for automotive and industrial environments requiring AEC-Q200 certification.

ERJ-6ENF1651V (Panasonic): Carries automotive AEC-Q200 qualification. Highest seated height (0.028" / 0.70mm) among substitutes. Largest available inventory (92,066 pcs). Suitable for high-volume procurement and automotive applications.

RC0805FR-071K65L (YAGEO): Moisture-resistant feature set matches the RCS2012F1651CS anti-sulfur and moisture-resistant properties. Mid-range seated height (0.024" / 0.60mm). Suitable for general industrial applications without automotive requirements.

RMCF0805FT1K65 (Stackpole): Carries automotive AEC-Q200 qualification. Seated height (0.026" / 0.65mm) matches the original RCS2012F1651CS specification. Suitable for automotive applications requiring AEC-Q200 compliance with dimensional consistency.

Selection criteria: Choose based on application environment (automotive vs. industrial), required certifications (AEC-Q200), and PCB layout constraints (seated height tolerance).

Frequently Asked Questions (FAQ)

Q: Can CRCW08051K65FKEA replace RCS2012F1651CS in any application?

A: Yes, within the specified electrical and mechanical parameters. The CRCW08051K65FKEA maintains identical resistance (1.65 kOhms), tolerance (±1%), power rating (0.125W), and package form factor (0805). The lower seated height (0.020" vs. 0.026") provides additional PCB clearance margin.

Q: What is the difference between automotive AEC-Q200 qualified parts and non-qualified parts?

A: AEC-Q200 qualification indicates the component meets automotive industry reliability and performance standards. CRCW08051K65FKEA, ERJ-6ENF1651V, and RMCF0805FT1K65 carry this certification. The RCS2012F1651CS and RC0805FR-071K65L do not list AEC-Q200 qualification. Selection depends on application requirements.

Q: Are there any height restrictions when substituting these parts?

A: Seated height varies from 0.020" (CRCW08051K65FKEA) to 0.028" (ERJ-6ENF1651V). Verify PCB layout and component clearance requirements. All heights remain within typical 0805 package specifications and do not affect electrical performance.

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

A: Yes. All parts listed carry MSL Level 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.

Q: Which substitute part has the largest inventory availability?

A: ERJ-6ENF1651V (Panasonic) offers the highest inventory level at 92,066 pcs, followed by RC0805FR-071K65L (YAGEO) at 48,291 pcs. Inventory levels support high-volume production requirements.

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

A: Yes. All parts share identical electrical specifications, package form factor (0805), and compliance certifications (ROHS3, MSL Level 1). Mechanical variations (seated height) are within standard 0805 package tolerances and do not affect PCB assembly compatibility.
