RC3225F6813CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F6813CS is a 681 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1210 (3225 Metric) package format. This component is rated for 0.333W (1/3W) power dissipation with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status and carries ROHS3 compliance with MSL Level 1 (Unlimited moisture sensitivity).

Substitute parts are identified when equivalent resistance values, tolerance specifications, and package dimensions align with the original component, enabling direct functional replacement in circuit applications. Substitution becomes necessary when the primary part experiences supply constraints, inventory limitations, or when design requirements permit higher power ratings or enhanced automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC3225F6813CS are qualified based on the following critical parameters that determine functional equivalence:

Mandatory Matching Parameters:

• Resistance value: 681 kOhms
• Tolerance: ±1%
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

Allowable Variation Parameters:

• Power rating: Substitutes may exceed the 0.333W specification (0.5W acceptable)
• Packaging format: Original tube or Tape & Reel (TR) formats are interchangeable
• Automotive qualification: AEC-Q200 certification is an enhancement, not a requirement
• Product status: Active or Not For New Designs both qualify as functional substitutes

The identified substitute parts CRCW1210681KFKEA (Vishay Dale) and ERJ-14NF6813U (Panasonic Electronic Components) meet all mandatory parameters while offering higher power dissipation ratings and automotive-grade certifications.

Parameter Comparison

Engineering Selection Recommendations

CRCW1210681KFKEA (Vishay Dale) is the primary substitute for new designs and production applications. This part maintains Active product status, carries ROHS3 compliance, and provides AEC-Q200 automotive qualification. The 0.5W power rating exceeds the original specification, offering improved thermal margin. Dimensional compatibility is confirmed within acceptable PCB layout tolerances. Tape & Reel packaging supports automated assembly processes.

ERJ-14NF6813U (Panasonic Electronic Components) functions as a secondary substitute option. Although marked as "Not For New Designs," this part meets all electrical and mechanical compatibility requirements. The AEC-Q200 automotive certification and 0.5W power rating provide equivalent or superior performance characteristics. Selection of this part is appropriate for legacy system maintenance, repair applications, or when supply chain constraints limit primary substitute availability.

Both substitute parts demonstrate full compliance with RoHS3 and REACH requirements, matching the environmental and regulatory status of the original RC3225F6813CS component.

Frequently Asked Questions (FAQ)

Q: Can CRCW1210681KFKEA replace RC3225F6813CS in existing designs?

A: Yes. Both parts share identical resistance (681 kOhms), tolerance (±1%), package format (1210), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The CRCW1210681KFKEA provides higher power dissipation (0.5W versus 0.333W), which is functionally compatible. Dimensional variations are within acceptable PCB assembly tolerances.

Q: What is the difference between the Samsung RC3225F6813CS and Vishay CRCW1210681KFKEA?

A: The primary differences are power rating (0.333W versus 0.5W), packaging format (tube versus Tape & Reel), and automotive qualification (standard versus AEC-Q200). All critical electrical parameters and package dimensions are equivalent. The Vishay part offers enhanced thermal capability and automotive-grade reliability.

Q: Is ERJ-14NF6813U suitable for new product designs?

A: The ERJ-14NF6813U carries a "Not For New Designs" status, indicating Panasonic has designated this part for legacy applications only. For new designs, CRCW1210681KFKEA is the recommended substitute. ERJ-14NF6813U remains appropriate for maintenance, repair, or retrofit applications where the original part is unavailable.

Q: Are there dimensional compatibility concerns when substituting these parts?

A: Dimensional variations exist within the 1210 package family. The RC3225F6813CS measures 0.126" L x 0.100" W with 0.026" maximum height. Substitutes measure 0.126" L x 0.098" W with heights ranging from 0.024" to 0.028". These variations fall within standard PCB design tolerances and do not prevent direct substitution on existing layouts.

Q: Do all substitute parts meet RoHS and REACH compliance?

A: Yes. RC3225F6813CS, CRCW1210681KFKEA, and ERJ-14NF6813U all carry ROHS3 Compliant status and REACH Unaffected designation. Environmental and regulatory compliance is maintained across all three parts.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity limitations. These parts do not require special moisture-controlled storage, handling, or baking procedures prior to soldering. All three parts share this MSL 1 classification.

Q: Can these resistors be used in automotive applications?

A: The RC3225F6813CS is standard industrial grade. CRCW1210681KFKEA and ERJ-14NF6813U both carry AEC-Q200 automotive qualification, meeting automotive reliability and testing standards. For automotive applications, CRCW1210681KFKEA is the preferred substitute.
