RC3225F57R6CS Equivalent & Substitute Parts

Part Overview

The RC3225F57R6CS is a 57.6 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 and is designed for moisture-resistant applications across an operating temperature range of -55°C to 155°C. The part maintains Active product status and is currently in stock with 1066 units available.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit the use of alternative manufacturers' components that meet or exceed the electrical and mechanical specifications of the original part.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F57R6CS is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• Resistance value: 57.6 Ohms
• Tolerance: ±1%
• Package format: 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 be equal to or greater than 0.333W (1/3W)
• Moisture Sensitivity Level must be 1 (Unlimited) or equivalent
• Physical dimensions must remain within 1210 package specifications

The ERJ-14NF57R6U from Panasonic Electronic Components qualifies as a substitute part. While this component carries a higher power rating of 0.5W (1/2W) and includes automotive AEC-Q200 certification, it maintains all critical electrical parameters and package specifications identical to the RC3225F57R6CS.

Parameter Comparison

Engineering Selection Recommendations

Primary Component Selection: The RC3225F57R6CS remains the recommended choice for new designs. This component maintains Active product status, ensuring long-term availability and manufacturer support. The part is RoHS3 compliant and carries unlimited moisture sensitivity rating, suitable for standard industrial and commercial applications.

Substitute Component Consideration: The ERJ-14NF57R6U from Panasonic Electronic Components serves as a functional equivalent for existing designs or applications where supply of the primary part is unavailable. This substitute maintains identical electrical specifications and package dimensions. The higher power rating of 0.5W (1/2W) compared to the original 0.333W (1/3W) specification provides additional thermal margin in the application circuit.

The ERJ-14NF57R6U carries "Not For New Designs" status, indicating it is suitable for replacement and maintenance applications but should not be selected for new product development. The inclusion of automotive AEC-Q200 certification on the substitute part provides additional quality assurance for applications requiring automotive-grade reliability.

Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-14NF57R6U replace the RC3225F57R6CS in my circuit?

A: Yes. The ERJ-14NF57R6U is electrically and mechanically compatible with the RC3225F57R6CS. Both components share identical resistance value (57.6 Ohms), tolerance (±1%), package format (1210), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The substitute part carries a higher power rating (0.5W versus 0.333W), which does not create compatibility issues in applications designed for the original part.

Q: What is the difference in physical dimensions between these parts?

A: Both components conform to the 1210 (3225 Metric) package standard. The RC3225F57R6CS measures 0.126" L x 0.100" W (3.20mm x 2.55mm) with a maximum seated height of 0.026" (0.66mm). The ERJ-14NF57R6U measures 0.126" L x 0.098" W (3.20mm x 2.50mm) with a maximum seated height of 0.028" (0.70mm). These dimensional variations remain within standard 1210 package tolerances and do not affect PCB layout or assembly compatibility.

Q: Why does the substitute part have a higher power rating?

A: The ERJ-14NF57R6U is rated for 0.5W (1/2W) power dissipation compared to the original 0.333W (1/3W) specification. This higher rating reflects the substitute manufacturer's design and thermal characteristics. In applications where the original part is rated for 0.333W, the substitute part's higher rating provides additional thermal headroom and does not create any functional or reliability concerns.

Q: Are both parts RoHS compliant?

A: Yes. Both the RC3225F57R6CS and ERJ-14NF57R6U are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What does "Not For New Designs" mean for the substitute part?

A: The ERJ-14NF57R6U carries "Not For New Designs" product status, indicating that Panasonic Electronic Components does not recommend this part for new product development. This status reflects the manufacturer's product lifecycle management strategy. The part remains suitable for replacement, maintenance, and repair of existing equipment. For new designs, the RC3225F57R6CS with Active status is the preferred selection.

Q: Can I use these parts interchangeably in my existing inventory?

A: Yes. Both components are functionally equivalent for applications designed around the RC3225F57R6CS specifications. The identical electrical parameters, package format, and environmental ratings ensure interchangeability. However, for new designs, the RC3225F57R6CS should be specified due to its Active product status and long-term availability assurance.
