RC3225F3480CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F3480CS is a 348 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.333W (1/3W) in a 1210 (3225 Metric) package. This component is classified as Active product status with 802 units currently in stock. The part features moisture-resistant construction, operates across -55°C to 155°C, and complies with ROHS3 and REACH standards.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating, temperature coefficient, operating temperature range) and mechanical compatibility (package type, dimensions, termination count). Substitute parts may vary in power rating, product status, or automotive qualification while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F3480CS is determined by the following mandatory parameters:

Electrical Compatibility Requirements:

• Resistance value: 348 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)
• Composition: Thick Film (exact match required)

Mechanical Compatibility Requirements:

• Package / Case: 1210 (3225 Metric) (exact match required)
• Number of Terminations: 2 (exact match required)

Allowable Variations:

• Power Rating: Substitute parts may have equal or higher power rating (0.333W or greater)
• Product Status: Active or Not For New Designs
• Automotive Qualification: May be present in substitutes (AEC-Q200)
• Packaging Format: May differ (Tape & Reel vs. other formats)
• Manufacturer: Different manufacturers acceptable if all parameters match

Engineering Selection Recommendations

Primary Selection (RC3225F3480CS - Samsung Electro-Mechanics): Select the RC3225F3480CS for new designs requiring a 348 Ohm 1% thick film resistor in 1210 package. This part carries Active product status, ensuring long-term availability and manufacturer support. It is ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Secondary Selection (RMCF1210FT348R - Stackpole Electronics Inc): The RMCF1210FT348R is suitable as a direct substitute where higher power dissipation capability (0.5W vs. 0.333W) is beneficial or required. This part maintains Active product status and includes AEC-Q200 automotive qualification. Mechanical dimensions are within acceptable tolerance for 1210 package applications. ROHS3 compliance and REACH unaffected status are maintained.

Tertiary Selection (ERJ-14NF3480U - Panasonic Electronic Components): The ERJ-14NF3480U is electrically and mechanically compatible but carries Not For New Designs product status. This designation indicates Panasonic is not recommending this part for new circuit designs. Use only in legacy system maintenance or where existing design documentation specifies this part number. AEC-Q200 automotive qualification is present. ROHS3 compliance and REACH unaffected status apply.

Selection Criteria Summary:

• For new designs: RC3225F3480CS or RMCF1210FT348R
• For legacy systems: Any of the three parts based on existing design specifications
• For automotive applications: RMCF1210FT348R or ERJ-14NF3480U (both AEC-Q200 qualified)
• For general industrial applications: RC3225F3480CS (Active status, no automotive requirement)

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF3480U replace RC3225F3480CS in new designs?

A: ERJ-14NF3480U is electrically and mechanically compatible but carries Not For New Designs product status from Panasonic. For new circuit designs, use RC3225F3480CS or RMCF1210FT348R instead.

Q: What is the difference between the 0.333W and 0.5W power ratings?

A: RC3225F3480CS is rated at 0.333W (1/3W), while ERJ-14NF3480U and RMCF1210FT348R are rated at 0.5W (1/2W). The higher power rating in substitute parts allows greater current handling capability. Substitution with higher power rating is acceptable; the component will operate within safe thermal limits in applications designed for the lower rating.

Q: Are the physical dimensions identical across all three parts?

A: Dimensions are within 1210 package specification tolerance. RC3225F3480CS measures 0.126" L x 0.100" W (3.20mm x 2.55mm) with 0.026" max height. ERJ-14NF3480U and RMCF1210FT348R measure 0.126" L x 0.098" W (3.20mm x 2.50mm) with 0.028" max height. These minor variations are within standard 1210 package tolerances and do not affect PCB layout compatibility.

Q: Do all three parts meet RoHS and REACH compliance?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive industry standard qualification for passive components. ERJ-14NF3480U and RMCF1210FT348R carry this qualification, indicating suitability for automotive applications. RC3225F3480CS does not specify AEC-Q200 but is suitable for general industrial and consumer applications.

Q: Can I use RMCF1210FT348R as a direct replacement in existing assemblies?

A: Yes. RMCF1210FT348R is mechanically and electrically compatible with RC3225F3480CS. The slightly higher power rating and AEC-Q200 qualification do not create compatibility issues in existing designs. Verify PCB layout accommodates the maximum height specification of 0.028" (0.70mm).

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life without moisture control requirements. All three parts carry MSL 1, meaning they do not require special dry-pack storage or handling procedures.
