RC3225F23R7CS Equivalent & Substitute Parts

Part Overview

The RC3225F23R7CS is a 23.7 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 operates across the temperature range of -55°C to 155°C. The part is currently in active production status with moisture resistant characteristics and ROHS3 compliance.

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 RC3225F23R7CS is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 23.7 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)
• Physical dimensions may vary within standard 1210 package tolerances
• Moisture Sensitivity Level remains at 1 (Unlimited)

The ERJ-14NF23R7U from Panasonic Electronic Components qualifies as a substitute part. While its power rating is 0.5W (1/2W), which exceeds the original specification, this represents an acceptable upgrade that maintains full compatibility with the electrical and mechanical requirements of the RC3225F23R7CS.

Parameter Comparison

Engineering Selection Recommendations

RC3225F23R7CS (Samsung Electro-Mechanics): This component is the primary selection for new designs. The part maintains active production status, ensuring long-term availability and supply chain stability. ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1) support deployment in standard industrial and commercial environments.

ERJ-14NF23R7U (Panasonic Electronic Components): This substitute part is electrically and mechanically compatible with the RC3225F23R7CS. The higher power rating (0.5W versus 0.333W) provides additional thermal margin in applications where the original specification is met or exceeded. However, the product status designation "Not For New Designs" indicates this part is in end-of-life phase. The ERJ-14NF23R7U is suitable for replacement, repair, and legacy system applications where supply of the primary part is unavailable. The automotive AEC-Q200 qualification of this part provides additional reliability assurance for demanding environments.

Both parts carry identical RoHS3 compliance and MSL 1 ratings, confirming regulatory and environmental compatibility.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-14NF23R7U replace the RC3225F23R7CS in existing designs?

A: Yes. The ERJ-14NF23R7U meets all mandatory electrical parameters (23.7 Ohms, ±1% tolerance, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range) and package requirements (1210 / 3225 Metric). The higher power rating (0.5W versus 0.333W) is an acceptable upgrade that does not compromise circuit performance.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF23R7U?

A: This designation indicates the part is in end-of-life production phase. While the component remains functionally equivalent and available in current inventory, Panasonic does not recommend its use in new product development. The RC3225F23R7CS should be the primary selection for new designs to ensure long-term supply availability.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within standard 1210 package tolerances. The RC3225F23R7CS 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-14NF23R7U measures 0.126" L x 0.098" W (3.20mm x 2.50mm) with a maximum seated height of 0.028" (0.70mm). These differences fall within acceptable PCB layout and assembly specifications for 1210 package components.

Q: Do both parts require identical handling and storage procedures?

A: Yes. Both components carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating no special moisture control requirements during storage or handling. Standard ESD precautions and dry storage conditions are appropriate for both parts.

Q: What compliance certifications apply to both parts?

A: Both the RC3225F23R7CS and ERJ-14NF23R7U are ROHS3 compliant and REACH unaffected. The ERJ-14NF23R7U carries additional automotive AEC-Q200 qualification, which may be relevant for applications requiring automotive-grade component reliability.
