Part Overview

The RCS2012F6812CS is a 68.1 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 characteristics. The part is ROHS3 compliant and operates across -55°C to 155°C temperature range.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating) and mechanical compatibility (package type, dimensions, termination count). Alternative sources become necessary for supply chain continuity, inventory availability, or application-specific requirements such as automotive qualification or enhanced pulse withstanding capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters:

Mandatory Matching Parameters:

• Resistance value: 68.1 kOhms
• Tolerance: ±1%
• Package / Case: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Number of Terminations: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Power Rating: 0.125W (1/8W) or higher (0.5W / 1/2W acceptable for applications with lower power dissipation requirements)
• Height - Seated (Max): Variations within 0.020" to 0.028" (0.50mm to 0.70mm) acceptable for standard PCB assembly
• Features: Additional certifications (AEC-Q200, Pulse Withstanding) or enhanced characteristics (Anti-Sulfur, Moisture Resistant) do not disqualify substitution

Substitute parts are grouped into two categories based on power rating compatibility with the original 0.125W specification.

Parameter Comparison

Engineering Selection Recommendations

Category 1: Direct Equivalents (0.125W Power Rating)

CRCW080568K1FKEA, ERJ-6ENF6812V, RC0805FR-0768K1L, and RMCF0805FT68K1 are direct electrical and mechanical equivalents to RCS2012F6812CS. All maintain identical resistance, tolerance, power rating, package dimensions, and temperature specifications. These parts are suitable for one-to-one replacement in applications where the original 0.125W power dissipation requirement is maintained.

CRCW080568K1FKEA (Vishay Dale), ERJ-6ENF6812V (Panasonic), and RMCF0805FT68K1 (Stackpole) carry AEC-Q200 automotive qualification, providing enhanced reliability documentation for automotive and industrial applications. RC0805FR-0768K1L (YAGEO) offers moisture-resistant characteristics comparable to the original part.

Category 2: Higher Power Rating Substitutes (0.5W Power Rating)

CRCW080568K1FKEAHP and RCS080568K1FKEA feature 0.5W power rating while maintaining all other electrical and mechanical specifications. These parts are suitable for applications where the original design margin permits higher power dissipation capability or where future design modifications may require increased power handling. Both parts carry AEC-Q200 automotive qualification and pulse withstanding capability.

All substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), and identical operating temperature range (-55°C ~ 155°C). Selection between alternatives should be based on supply chain availability, packaging preference (Tape & Reel vs. Cut Tape), and application-specific certifications.

Frequently Asked Questions (FAQ)

Q1: Can CRCW080568K1FKEAHP (0.5W) be used as a direct replacement for RCS2012F6812CS (0.125W)?

A: Yes. The 0.5W part is mechanically and electrically compatible. The higher power rating does not create incompatibility; it provides additional thermal margin. The part occupies the same 0805 (2012 Metric) footprint with identical lead spacing and termination configuration. Use this substitute when supply constraints exist or when design requirements permit higher power dissipation capability.

Q2: What is the significance of AEC-Q200 certification on substitute parts?

A: AEC-Q200 is an automotive industry qualification standard. Parts carrying this certification (CRCW080568K1FKEA, ERJ-6ENF6812V, RMCF0805FT68K1, CRCW080568K1FKEAHP, RCS080568K1FKEA) have undergone enhanced reliability testing and documentation. These parts are suitable for automotive applications and applications requiring automotive-grade component reliability. Non-automotive applications may use either AEC-Q200 qualified or non-qualified equivalents.

Q3: Are there packaging differences between substitute parts?

A: Yes. RCS2012F6812CS and most substitutes are supplied in Tape & Reel (TR) packaging. RC0805FR-0768K1L is available in Cut Tape (CT) & Digi-Reel® packaging. Tape & Reel packaging is standard for automated assembly; Cut Tape is suitable for lower-volume or manual assembly operations. Verify packaging compatibility with your assembly process requirements.

Q4: Do height variations between substitute parts affect PCB assembly?

A: Height variations range from 0.020" (0.50mm) to 0.028" (0.70mm) seated maximum. These variations are within standard PCB assembly tolerances and do not affect component placement, solder reflow, or electrical performance. All parts are compatible with standard 0805 footprints and assembly equipment.

Q5: Which substitute part offers the best supply availability?

A: RMCF0805FT68K1 (Stackpole Electronics) shows highest inventory (242,759 pcs), followed by ERJ-6ENF6812V (Panasonic, 131,042 pcs) and RC0805FR-0768K1L (YAGEO, 149,911 pcs). Inventory levels are subject to change; verify current availability with your component supplier.

Q6: Can I mix different substitute parts within the same assembly?

A: Yes. All substitute parts meet identical electrical specifications (68.1 kOhms ±1%, ±100ppm/°C, -55°C ~ 155°C). Mixing different manufacturers within the same circuit board is acceptable from an electrical and thermal perspective. Verify that your quality and traceability procedures permit multi-source component usage.

Q7: What is the difference between "Anti-Sulfur" and "Moisture Resistant" features?

A: Anti-Sulfur protection prevents corrosion from sulfur-containing environmental contaminants. Moisture Resistant construction reduces susceptibility to humidity-induced performance degradation. Both features enhance component longevity in harsh environments. RCS2012F6812CS includes both characteristics; RC0805FR-0768K1L includes Moisture Resistant; AEC-Q200 qualified parts include standard environmental protection. Feature differences do not affect substitution eligibility.
