RC3225F2611CS Equivalent & Substitute Parts

Part Overview

The RC3225F2611CS is a 2.61 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1210 (3225 Metric) package format. This moisture-resistant component is rated for 0.333W (1/3W) power dissipation and operates across the temperature range of -55°C to 155°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing, higher power ratings, automotive qualification, or different manufacturer availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC3225F2611CS are qualified based on the following critical parameters that must remain constant or be compatible with the original design:

Mandatory Matching Parameters:

• Resistance value: 2.61 kOhms
• Tolerance: ±1%
• Package / Case: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: Substitute parts may have equal or higher power ratings (0.5W or greater) without affecting circuit compatibility, as higher power ratings provide additional thermal margin
• Physical dimensions: Minor variations in height and width are acceptable within the 1210 package specification
• Packaging format: Tape & Reel (TR) packaging is compatible with the original component for automated assembly

The identified substitute parts CRCW12102K61FKEA (Vishay Dale) and ERJ-14NF2611U (Panasonic Electronic Components) meet all mandatory parameters while offering enhanced power ratings of 0.5W (1/2W) and automotive AEC-Q200 qualification.

Parameter Comparison

Engineering Selection Recommendations

RC3225F2611CS (Samsung Electro-Mechanics): Select this part for applications requiring the original specification with standard industrial-grade thick film resistor performance. The component is in active production status and suitable for new designs. Use when power dissipation does not exceed 0.333W and automotive qualification is not required.

CRCW12102K61FKEA (Vishay Dale): This substitute is recommended for designs requiring higher power dissipation capability (0.5W) or automotive-grade reliability. The part carries AEC-Q200 qualification and is in active production status, making it suitable for new designs. The increased power rating provides additional thermal margin in applications approaching the original component's power limit.

ERJ-14NF2611U (Panasonic Electronic Components): This substitute offers equivalent electrical performance and AEC-Q200 automotive qualification. However, the product status is listed as "Not For New Designs," indicating this part is in end-of-life phase. Use only for legacy system maintenance, repair, or replacement of existing assemblies where continuity with original component sourcing is required.

Frequently Asked Questions (FAQ)

Q: Can CRCW12102K61FKEA be used as a direct replacement for RC3225F2611CS?

A: Yes. Both components share identical resistance (2.61 kOhms), tolerance (±1%), package (1210), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, MSL 1). The CRCW12102K61FKEA has a higher power rating (0.5W versus 0.333W), which is compatible with the original design and provides additional thermal margin.

Q: What is the difference between the Samsung and Vishay parts?

A: The primary differences are manufacturer, power rating, and automotive qualification. The Vishay CRCW12102K61FKEA is rated for 0.5W (versus 0.333W for Samsung) and carries AEC-Q200 automotive certification. All other electrical and mechanical parameters are identical. Both parts are in active production.

Q: Why is ERJ-14NF2611U marked "Not For New Designs"?

A: The ERJ-14NF2611U is in end-of-life status, meaning Panasonic is discontinuing this product line. While the component remains functionally equivalent to the original RC3225F2611CS, it should not be selected for new product designs. This part is appropriate only for maintaining or repairing existing systems already using this component.

Q: Are there any physical dimension differences between these parts?

A: Minor variations exist within the 1210 package specification. The RC3225F2611CS has a maximum seated height of 0.026" (0.66mm), while both substitute parts have maximum seated heights of 0.024" (0.60mm) for Vishay and 0.028" (0.70mm) for Panasonic. These variations are within standard 1210 package tolerances and do not affect PCB assembly or circuit performance.

Q: Can I use these parts interchangeably in automated assembly?

A: Yes. All three parts are available in Tape & Reel (TR) packaging format compatible with standard pick-and-place assembly equipment. The 1210 package footprint is identical across all three components, allowing direct substitution in manufacturing processes without tooling changes.

Q: Which substitute should I select for a new automotive application?

A: Select CRCW12102K61FKEA (Vishay Dale). This part is in active production status and carries AEC-Q200 automotive qualification. The ERJ-14NF2611U, while also AEC-Q200 qualified, is marked "Not For New Designs" and should be avoided for new product development.
