Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F1823CS is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• Resistance value: 182 kOhms
• Tolerance: ±1%
• Package / Case: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: Substitute parts may have equal or higher power ratings (0.5W or greater) while maintaining the same package footprint and thermal characteristics.

Two substitute parts meet these criteria: ERJ-14NF1823U (Panasonic Electronic Components) and RMCF1210FT182K (Stackpole Electronics Inc). Both maintain identical electrical specifications and package compatibility while offering increased power dissipation capacity at 0.5W (1/2W).

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: RC3225F1823CS The RC3225F1823CS maintains Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating. This component is suitable for new design implementations requiring the specified 0.333W power rating within the 1210 package envelope.

Secondary Selection: RMCF1210FT182K The RMCF1210FT182K (Stackpole Electronics Inc) is an Active product with identical electrical and mechanical specifications to the main part. It provides increased power dissipation at 0.5W while maintaining all critical parameters. This substitute is appropriate for applications where higher thermal margin is required without changing the package footprint. AEC-Q200 automotive qualification is included.

Tertiary Selection: ERJ-14NF1823U The ERJ-14NF1823U (Panasonic Electronic Components) carries a "Not For New Designs" product status designation. While electrically and mechanically equivalent with 0.5W power rating and AEC-Q200 qualification, this part should be reserved for legacy system support or replacement applications only.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF1823U replace RC3225F1823CS in new designs? A: No. ERJ-14NF1823U carries "Not For New Designs" status. For new implementations, use RC3225F1823CS or RMCF1210FT182K.

Q: What is the difference between the 0.333W and 0.5W power ratings? A: Both substitute parts maintain identical package dimensions (1210/3225 Metric) and thermal characteristics. The 0.5W rating provides additional power dissipation capacity. Selection depends on circuit power requirements.

Q: Are all three parts mechanically interchangeable? A: Yes. All three parts use the 1210 (3225 Metric) package with identical footprints and two terminations. Physical board layout compatibility is maintained.

Q: Do the substitute parts maintain the same moisture resistance? A: Yes. All three parts have Moisture Sensitivity Level 1 (Unlimited) and ROHS3 compliance.

Q: Which substitute offers the best long-term availability? A: RMCF1210FT182K (Stackpole Electronics Inc) maintains Active product status with no design restrictions, ensuring continued availability for future production runs.

Q: Are AEC-Q200 certifications required for my application? A: AEC-Q200 automotive qualification is present in both substitute parts but not specified for the main RC3225F1823CS. Verify application requirements before selecting a substitute based on this criterion.
