RC2012F6340CS Equivalent & Substitute Parts

Part Overview

The RC2012F6340CS is a 634 Ohms ±1% 0.125W thick film chip resistor manufactured by Samsung Electro-Mechanics in 0805 (2012 Metric) package format. This component is currently active in production with 882 pieces available in stock. The part is designed for general-purpose applications requiring moisture-resistant thick film construction with standard industrial temperature range operation. Substitute parts are necessary to address supply chain continuity, alternative sourcing requirements, or specific application certifications such as automotive AEC-Q200 qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F6340CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 634 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package / Case: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Number of terminations: 2
• RoHS3 compliance

Allowable Variations:

• Packaging format (Tape & Reel vs. Cut Tape & Digi-Reel)
• Physical height when seated (within component specifications)
• Manufacturer-specific features (Moisture Resistant vs. Automotive AEC-Q200)
• Inventory availability

All identified substitute parts meet these mandatory parameters. Parts are grouped as "Direct" substitutes when packaging and feature sets align closely, and "Similar" substitutes when packaging or feature differences exist but electrical and mechanical specifications remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Tape & Reel Packaging, Active Status):

ERJ-6ENF6340V (Panasonic Electronic Components) and RC0805FR-07634RL (YAGEO) are direct electrical and mechanical equivalents to the RC2012F6340CS. Both maintain identical electrical specifications and are supplied in Tape & Reel format. ERJ-6ENF6340V includes Automotive AEC-Q200 certification, suitable for applications requiring automotive-grade reliability. RC0805FR-07634RL maintains moisture-resistant construction consistent with the primary part. Both manufacturers are actively producing these components with substantial inventory availability.

Direct Substitutes (Tape & Reel Packaging, Automotive Certified):

RMCF0805FT634R (Stackpole Electronics Inc) is electrically and mechanically equivalent with Automotive AEC-Q200 certification and Tape & Reel packaging. This part is suitable for automotive and industrial applications requiring AEC-Q200 qualification.

Similar Substitutes (Cut Tape & Digi-Reel Packaging, Active Status):

CRCW0805634RFKEA (Vishay Dale) meets all electrical and mechanical requirements with Automotive AEC-Q200 certification. This part is supplied in Cut Tape & Digi-Reel format rather than standard Tape & Reel, which may affect assembly line compatibility depending on pick-and-place equipment configuration.

Similar Substitutes (Discontinued Status):

MCR10ERTF6340 (Rohm Semiconductor) is electrically and mechanically equivalent but is discontinued at DiGi Electronics. This part should be selected only when existing inventory is available and long-term supply is not required.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6ENF6340V replace RC2012F6340CS in all applications?

A: Yes. ERJ-6ENF6340V meets all mandatory electrical and mechanical parameters. The primary difference is Automotive AEC-Q200 certification, which provides additional reliability qualification. This certification does not prevent use in non-automotive applications.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel packaging supplies components on continuous carrier tape suitable for high-speed automated assembly. Cut Tape & Digi-Reel packaging supplies components in smaller quantities on cut tape segments. Equipment compatibility depends on your assembly line's pick-and-place machine specifications. Verify your equipment supports the packaging format before selection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the primary part's environmental compliance status.

Q: Why do some parts have different seated heights?

A: Physical height variation (0.020" to 0.028") is within acceptable tolerance for 0805 package components and does not affect electrical performance or PCB assembly compatibility. Height differences result from manufacturer-specific construction methods.

Q: Is MCR10ERTF6340 still available for new designs?

A: MCR10ERTF6340 is discontinued at DiGi Electronics. This part should not be selected for new designs requiring long-term supply assurance. Use active alternatives: ERJ-6ENF6340V, RC0805FR-07634RL, RMCF0805FT634R, or CRCW0805634RFKEA.

Q: Can I use automotive-rated parts (AEC-Q200) in non-automotive applications?

A: Yes. Automotive-rated parts exceed standard industrial specifications and are fully compatible with non-automotive applications. No performance degradation occurs when using higher-grade components in standard applications.

Q: What is MSL 1 (Unlimited) rating?

A: MSL 1 indicates Moisture Sensitivity Level 1, the lowest moisture sensitivity classification. Components with this rating have unlimited shelf life and require no special moisture control during storage or handling.
