RC3225F3652CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F3652CS is a 36.5 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.333W (1/3W) power dissipation in a 1210 (3225 Metric) surface mount package. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and performance envelope. The primary substitute ERJ-14NF3652U from Panasonic Electronic Components shares identical resistance, tolerance, and package dimensions while offering increased power rating and automotive-grade qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F3652CS is determined by strict adherence to the following parameters:

Critical Matching Parameters (Non-Negotiable):

• Resistance value: 36.5 kOhms
• Tolerance: ±1%
• Package footprint: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C minimum
• RoHS3 compliance status

Allowable Variation Parameters:

• Power rating: Equal to or greater than 0.333W
• Physical dimensions: Within standard 1210 package tolerances
• Packaging format: Bulk, Tape & Reel, or alternative distribution methods
• Product status: Active or Not For New Designs (both acceptable for substitution purposes)
• Certifications: Additional qualifications (such as AEC-Q200) do not disqualify substitution

The ERJ-14NF3652U meets all critical matching parameters while exceeding the power rating specification at 0.5W (1/2W), providing enhanced thermal margin in applications requiring higher dissipation capacity.

Engineering Selection Recommendations

For Active Product Designs: The RC3225F3652CS maintains Active product status with unrestricted design-in eligibility. This component is the primary selection for new circuit implementations requiring 36.5 kOhms ±1% resistance in 1210 package format.

For Existing Designs or Supply Continuity: The ERJ-14NF3652U from Panasonic Electronic Components serves as a direct functional substitute. Although classified as Not For New Designs, this part maintains full electrical and mechanical compatibility with identical resistance, tolerance, temperature coefficient, and operating range specifications. The increased power rating (0.5W versus 0.333W) provides additional thermal headroom without circuit modification requirements.

Compliance Considerations: Both parts maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status. The ERJ-14NF3652U includes AEC-Q200 automotive qualification, which does not restrict its use in non-automotive applications and may provide additional reliability assurance in demanding environments.

Physical Integration: Dimensional variations between parts (width 2.55mm versus 2.50mm, height 0.66mm versus 0.70mm) remain within standard 1210 package tolerances and do not require PCB layout modifications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF3652U replace RC3225F3652CS in existing circuit boards?

A: Yes. The ERJ-14NF3652U is mechanically and electrically compatible. Both components share identical 1210 package footprint, resistance value (36.5 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). Physical dimensions fall within standard package tolerances. No PCB layout modifications are required.

Q: What is the significance of the higher power rating on the substitute part?

A: The ERJ-14NF3652U is rated at 0.5W (1/2W) compared to the RC3225F3652CS at 0.333W (1/3W). This higher rating indicates greater thermal dissipation capacity. In applications where the original part operates near its power limit, the substitute provides additional margin. The higher rating does not negatively impact circuit performance and may improve component reliability in thermally constrained environments.

Q: Does the "Not For New Designs" status of ERJ-14NF3652U affect its use as a substitute?

A: The "Not For New Designs" designation indicates Panasonic's product lifecycle status and does not restrict the part's technical suitability for substitution in existing designs. This status reflects manufacturer production planning rather than component performance or reliability limitations. The part remains fully functional and compliant with all specified electrical and environmental parameters.

Q: Are there packaging format differences between these parts?

A: The RC3225F3652CS is supplied in standard packaging format, while the ERJ-14NF3652U is available in Tape & Reel (TR) format. Both formats contain identical components; the difference is in distribution method. Tape & Reel packaging is standard for automated assembly processes and does not affect component electrical or mechanical characteristics.

Q: What does MSL 1 (Unlimited) moisture sensitivity rating mean for substitution?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Both the main part and substitute share this rating, ensuring identical moisture management requirements and storage conditions. This simplifies inventory management and eliminates moisture-related compatibility concerns.

Q: Are there any certifications or qualifications that differ between these parts?

A: The ERJ-14NF3652U includes AEC-Q200 automotive qualification, while the RC3225F3652CS does not specify this certification. AEC-Q200 qualification indicates enhanced reliability testing and is not a restriction for non-automotive applications. Both parts maintain identical RoHS3 compliance and REACH unaffected status.
