RC3225F2261CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F2261CS is a 2.26 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 with full RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and resistance value, allowing for direct board-level replacement in applications where the primary part becomes unavailable or when design requirements necessitate alternative manufacturer sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F2261CS is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 2.26 kOhms
• Tolerance: ±1%
• Package / Case: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Number of Terminations: 2
• RoHS3 Compliance

Allowable Variation:

• Power rating may exceed the original 0.333W specification, as higher power-rated components in the same package are electrically and mechanically compatible for direct substitution
• Packaging format (Tape & Reel vs. bulk) does not affect electrical or mechanical compatibility
• Additional features (Automotive AEC-Q200 certification, Pulse Withstanding capability) represent enhanced specifications that do not compromise substitution suitability

All identified substitute parts maintain identical resistance, tolerance, package dimensions, and thermal characteristics while meeting or exceeding the original component's performance envelope.

Engineering Selection Recommendations

Primary Substitute (Preferred): CRCW12102K26FKEA (Vishay Dale) is the recommended primary substitute. This component maintains Active product status, carries Automotive AEC-Q200 certification, and provides enhanced power rating (0.5W) within the identical 1210 package footprint. All electrical parameters match the original specification with no derating required.

Secondary Substitute (Active Status): ERJ-P14F2261U (Panasonic) is suitable for applications requiring pulse withstanding capability in addition to standard automotive qualification. This part maintains Active product status and provides the same 0.5W power rating with identical electrical characteristics.

Tertiary Substitute (Legacy Status): ERJ-14NF2261U (Panasonic) meets all electrical and mechanical compatibility requirements but carries "Not For New Designs" product status. This part is suitable only for replacement in existing production or legacy system maintenance where design changes are not feasible.

All substitute parts comply with RoHS3 requirements and maintain unlimited moisture sensitivity level (MSL 1), ensuring compatibility with standard PCB assembly and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can CRCW12102K26FKEA replace RC3225F2261CS in existing designs? A: Yes. CRCW12102K26FKEA is electrically and mechanically compatible. The higher power rating (0.5W vs. 0.333W) does not create compatibility issues and provides additional thermal margin. Physical dimensions are within acceptable tolerance for 1210 package footprints.

Q: What is the difference between the Panasonic ERJ-14NF2261U and ERJ-P14F2261U? A: Both parts are electrically identical with matching 2.26 kOhms resistance, ±1% tolerance, and 0.5W power rating in 1210 package. ERJ-P14F2261U adds pulse withstanding capability and maintains Active product status, while ERJ-14NF2261U is designated "Not For New Designs." For new applications, ERJ-P14F2261U is preferred.

Q: Are there physical dimension differences between substitute parts? A: Minor variations exist within the 1210 package specification. Length remains 0.126" (3.20mm) across all parts. Width ranges from 0.098" to 0.100" (2.50mm to 2.55mm), and seated height ranges from 0.024" to 0.028" (0.60mm to 0.70mm). These variations are within standard 1210 package tolerances and do not affect PCB pad compatibility.

Q: Do all substitute parts meet automotive qualification requirements? A: CRCW12102K26FKEA and both Panasonic parts (ERJ-14NF2261U and ERJ-P14F2261U) carry AEC-Q200 automotive certification. The original RC3225F2261CS does not specify automotive qualification. Automotive-qualified substitutes are suitable for both automotive and non-automotive applications.

Q: What is the significance of "Moisture Sensitivity Level 1 (Unlimited)"? A: MSL 1 indicates unlimited shelf life without moisture bake-out requirements. All listed parts and the original component share this specification, ensuring identical handling and storage requirements.

Q: Can these parts be used interchangeably in high-temperature applications? A: Yes. All parts maintain the identical operating temperature range of -55°C to 155°C and share the same ±100ppm/°C temperature coefficient, ensuring equivalent performance across the full thermal envelope.
