RC3225F2613CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F2613CS is a 261 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 is ROHS3 compliant with MSL 1 rating.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and critical performance parameters. Alternative sources become necessary due to inventory availability, supply chain optimization, or specific application requirements such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the RC3225F2613CS is based on the following criteria:

Mandatory Matching Parameters:

• Resistance value: 261 kOhms (exact match required)
• Tolerance: ±1% (substitute tolerance must be equal or tighter)
• Package footprint: 1210 (3225 Metric) (physical and electrical compatibility)
• Temperature coefficient: ±100ppm/°C (substitute must be equal or tighter)
• Operating temperature range: -55°C to 155°C (substitute must cover this range)
• Composition: Thick Film (electrical performance characteristics)

Allowable Variation Parameters:

• Power rating: Substitute must equal or exceed 0.333W
• Physical dimensions: Minor variations acceptable within package specification
• Packaging format: May differ (bulk, tape & reel) based on application needs
• Manufacturer: Different manufacturers acceptable if specifications align

The identified substitute ERJ-14NF2613U from Panasonic Electronic Components meets all mandatory parameters while providing a higher power rating (0.5W) and automotive-grade qualification (AEC-Q200).

Engineering Selection Recommendations

RC3225F2613CS (Samsung Electro-Mechanics) - Primary Selection:

• Active product status ensures continued availability and manufacturing support
• Suitable for general industrial and commercial applications
• Moisture-resistant construction with MSL 1 rating provides reliable performance in standard environments
• ROHS3 and REACH compliance meet current regulatory requirements

ERJ-14NF2613U (Panasonic Electronic Components) - Alternative Selection:

• Higher power rating (0.5W vs. 0.333W) provides additional thermal margin in power-dissipation-critical applications
• AEC-Q200 automotive qualification enables use in automotive and high-reliability applications
• Identical electrical specifications (resistance, tolerance, temperature coefficient) ensure functional equivalence
• Note: Product status is "Not For New Designs," indicating this part is in mature/legacy phase; use only when inventory or specific automotive requirements justify selection
• ROHS3 and REACH compliance maintained

Selection Criteria:

• For new designs with standard requirements: RC3225F2613CS
• For automotive applications or designs requiring AEC-Q200 qualification: ERJ-14NF2613U
• For applications with higher power dissipation margins: ERJ-14NF2613U
• For long-term supply assurance: RC3225F2613CS (Active status)

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF2613U be used as a direct replacement for RC3225F2613CS?

A: Yes, within the specified application parameters. Both parts share identical resistance (261 kOhms), tolerance (±1%), package (1210), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The ERJ-14NF2613U provides a higher power rating (0.5W vs. 0.333W), which is compatible with applications designed for the RC3225F2613CS. Physical dimensions are within acceptable tolerance for PCB footprint compatibility.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF2613U?

A: This designation indicates the part is in the mature or legacy phase of its product lifecycle. Panasonic continues to manufacture and support this component, but recommends newer alternatives for new product development. For existing designs or applications where this specific part is already qualified, continued use is acceptable. For new designs, evaluate the RC3225F2613CS or other active-status alternatives.

Q: Are there dimensional differences that affect PCB layout?

A: Minor dimensional variations exist within package specification tolerance. RC3225F2613CS measures 0.126" L x 0.100" W (3.20mm x 2.55mm) with 0.026" max height, while ERJ-14NF2613U measures 0.126" L x 0.098" W (3.20mm x 2.50mm) with 0.028" max height. These differences are within standard 1210 package tolerance and do not require PCB layout modification. Both parts are mechanically compatible with standard 1210 footprints.

Q: What is the difference between the moisture-resistant feature and MSL 1 rating?

A: Moisture-resistant construction refers to the component's physical design and material composition that resists moisture ingress during normal operation and storage. MSL 1 (Moisture Sensitivity Level 1) is an industry standard classification indicating unlimited shelf life without special moisture-control storage requirements. Both the RC3225F2613CS and ERJ-14NF2613U carry MSL 1 rating, meaning they do not require dry-pack storage or baking procedures before soldering.

Q: Can these parts be used interchangeably in automotive applications?

A: The RC3225F2613CS is suitable for general automotive use. The ERJ-14NF2613U carries AEC-Q200 automotive qualification, which certifies it for automotive-grade reliability and environmental stress testing. For applications requiring formal automotive qualification documentation, use ERJ-14NF2613U. For non-critical automotive applications, RC3225F2613CS is acceptable.

Q: What compliance certifications apply to both parts?

A: Both RC3225F2613CS and ERJ-14NF2613U are ROHS3 compliant and REACH unaffected. Both carry ECCN classification EAR99 and HTSUS code 8533.21.0030. These certifications ensure compliance with current environmental and trade regulations for industrial and commercial markets.
