RC2012F68R1CS Equivalent & Substitute Parts Reference

Part Overview

The RC2012F68R1CS is a 68.1 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 is classified as Active product status with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Equivalent and substitute parts are identified when alternative manufacturers offer components with identical electrical specifications, mechanical dimensions, and package compatibility. Substitute sourcing becomes necessary due to supply chain availability, lead time requirements, inventory levels, or specific application certifications such as automotive AEC-Q200 qualification.

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F68R1CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 68.1 Ohms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 0.125W / 1/8W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C ~ 155°C (exact match)

Mechanical Equivalence Requirements:

• Package / Case: 0805 (2012 Metric) (exact match)
• Size / Dimension: 0.079" L x 0.049" W / 2.00mm x 1.25mm (exact match)
• Number of terminations: 2 (exact match)

Compliance & Environmental Requirements:

• Composition: Thick Film (exact match)
• RoHS Status: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match)
• REACH Status: REACH Unaffected or REACH Affected (both acceptable for substitution)

Substitute parts are classified as Direct Substitutes when all electrical, mechanical, and compliance parameters match exactly. Parts are classified as Similar Substitutes when all critical parameters match but may include additional certifications (such as AEC-Q200 automotive qualification) or minor variations in packaging format (Cut Tape vs. Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

Direct Substitute Selection (Preferred for Drop-In Replacement):

The following parts are direct electrical and mechanical equivalents with identical compliance status:

• CR0805-FX-68R1ELF (Bourns Inc.) – ROHS3 compliant, Tape & Reel packaging, 24,294 units in stock
• RC0805FR-0768R1L (YAGEO) – ROHS3 compliant, Tape & Reel packaging, 4,494 units in stock
• CRCW080568R1FKEA (Vishay Dale) – ROHS3 compliant, Tape & Reel packaging, 20,156 units in stock

Extended Substitute Selection (Automotive-Qualified Applications):

For applications requiring automotive-grade components with AEC-Q200 certification:

• ERJ-6ENF68R1V (Panasonic Electronic Components) – ROHS3 compliant, AEC-Q200 rated, 115,979 units in stock
• RMCF0805FT68R1 (Stackpole Electronics Inc) – ROHS3 compliant, AEC-Q200 rated, 24,609 units in stock

Non-Compliant Alternative (Legacy Applications Only):

• CRCW080568R1FKTA (Vishay Dale) – RoHS non-compliant, REACH Affected status. This part is suitable only for applications where RoHS3 compliance is not required and legacy inventory management is acceptable.

All recommended substitutes maintain identical electrical performance, thermal characteristics, and mechanical fit within the 0805 package envelope. Selection should be based on supply chain availability, packaging format requirements (Cut Tape vs. Tape & Reel), and application-specific certifications.

Frequently Asked Questions (FAQ)

Q1: Can I use ERJ-6ENF68R1V or RMCF0805FT68R1 in place of RC2012F68R1CS in non-automotive applications?

A: Yes. Both ERJ-6ENF68R1V and RMCF0805FT68R1 are direct electrical and mechanical equivalents. The AEC-Q200 automotive certification is an additional qualification that does not restrict use in non-automotive applications. All electrical parameters, package dimensions, and compliance certifications are identical to the RC2012F68R1CS.

Q2: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape packaging supplies individual components cut from a continuous tape, typically used for small-quantity orders or manual assembly. Tape & Reel packaging supplies components on continuous tape wound on reels, optimized for high-volume automated assembly. Electrically and mechanically, the components are identical. The RC2012F68R1CS is supplied in Cut Tape format; all listed substitutes are supplied in Tape & Reel format except where noted.

Q3: Are there any height differences that could affect PCB assembly?

A: Height variations exist within the 0805 package specification. The RC2012F68R1CS has a maximum seated height of 0.65mm (0.026"). Substitute parts range from 0.50mm to 0.70mm maximum height. These variations fall within standard 0805 package tolerances and do not affect PCB assembly compatibility or solder reflow processes.

Q4: Is CRCW080568R1FKTA suitable as a substitute?

A: CRCW080568R1FKTA is electrically and mechanically equivalent but carries RoHS non-compliant status and REACH Affected designation. This part is suitable only for applications where RoHS3 compliance is not a requirement. For new designs or applications requiring regulatory compliance, use ROHS3-compliant alternatives.

Q5: Which substitute has the highest inventory availability?

A: ERJ-6ENF68R1V (Panasonic Electronic Components) has the highest inventory level at 115,979 units in stock, followed by RMCF0805FT68R1 (Stackpole Electronics Inc) at 24,609 units and CR0805-FX-68R1ELF (Bourns Inc.) at 24,294 units.

Q6: Do all substitutes meet the ±100ppm/°C temperature coefficient specification?

A: Yes. All listed substitute parts maintain the identical ±100ppm/°C temperature coefficient and -55°C to 155°C operating temperature range as the RC2012F68R1CS.

Q7: Are there any moisture sensitivity differences between the main part and substitutes?

A: No. All parts, including the main part RC2012F68R1CS and all substitutes, carry MSL 1 (Unlimited) moisture sensitivity level rating, indicating no moisture precautions are required during storage or handling.
