RC3225F2610CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F2610CS is a 261 Ohm ±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 1109 units currently in stock.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained within the allowable parameter tolerances for this resistor category. Alternative sources may be required due to inventory availability, supply chain considerations, or specific application certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F2610CS is determined by the following criteria:

Mandatory Matching Parameters:

• Resistance Value: 261 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 1210 (3225 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (minimum requirement)
• RoHS Status: ROHS3 Compliant (minimum requirement)

Allowable Variation Parameters:

• Power Rating: Substitute parts may exceed the 0.333W specification, provided the higher power rating does not introduce incompatibility with the application circuit design
• Physical Dimensions: Minor variations within standard 1210 package tolerances are acceptable
• Packaging Format: Original packaging format (Tape & Reel) may differ from substitute availability

The identified substitute parts meet all mandatory matching parameters while maintaining or exceeding environmental and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection - RC3225F2610CS (Samsung Electro-Mechanics): This part maintains Active product status and is the specified original component. Selection is appropriate for applications where Samsung sourcing is preferred or contractually required. Current inventory of 1109 units supports immediate availability.

Secondary Selection - CRCW1210261RFKEA (Vishay Dale): This substitute maintains Active product status with higher power rating (0.5W vs. 0.333W), providing additional thermal margin in the application circuit. AEC-Q200 automotive qualification is included. Inventory of 14054 units ensures supply continuity. This part is suitable for new designs and applications requiring automotive-grade components.

Tertiary Selection - ERJ-14NF2610U (Panasonic Electronic Components): This substitute carries "Not For New Designs" product status, indicating end-of-life trajectory. While electrically and mechanically equivalent with AEC-Q200 automotive qualification, this part should be reserved for legacy system maintenance or replacement applications only. Highest inventory availability (24188 units) may support specific high-volume legacy requirements.

All three parts satisfy ROHS3 compliance, REACH unaffected status, and EAR99 export classification requirements.

Frequently Asked Questions (FAQ)

Q: Can CRCW1210261RFKEA replace RC3225F2610CS in existing designs?

A: Yes. Both parts share identical resistance value (261 Ohms), tolerance (±1%), package format (1210), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The CRCW1210261RFKEA provides higher power rating (0.5W vs. 0.333W), which is compatible with circuits designed for the lower-rated component. Physical dimensions remain within 1210 package specifications.

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

A: The primary electrical and mechanical specifications are identical. The CRCW1210261RFKEA includes AEC-Q200 automotive qualification, which the RC3225F2610CS does not specify. The Vishay part has higher power dissipation capability (0.5W). Both maintain Active product status and ROHS3 compliance.

Q: Why is ERJ-14NF2610U marked "Not For New Designs"?

A: This designation indicates the part is in end-of-life phase. While functionally equivalent and currently in stock, Panasonic has discontinued active development and promotion of this product line. New designs should utilize RC3225F2610CS or CRCW1210261RFKEA. The ERJ-14NF2610U remains suitable for replacement or maintenance of existing systems.

Q: Are there packaging differences between these parts?

A: All three parts are supplied in 1210 (3225 Metric) package format. The RC3225F2610CS and substitute parts may differ in tape & reel specifications or bulk packaging options. Verify packaging format requirements with your procurement specification before ordering.

Q: Do all parts meet moisture and environmental requirements?

A: Yes. All three parts maintain Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions. All are ROHS3 compliant and REACH unaffected. Operating temperature range is identical across all parts (-55°C to 155°C).

Q: Which part should I select for automotive applications?

A: CRCW1210261RFKEA and ERJ-14NF2610U both carry AEC-Q200 automotive qualification. For new automotive designs, CRCW1210261RFKEA is recommended due to Active product status. The RC3225F2610CS does not specify automotive qualification.
