RC3225F5900CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F5900CS is a 590 Ohms ±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 with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with 1032 units currently in stock.

Substitute parts become necessary when addressing supply chain constraints, design upgrades requiring higher power ratings, automotive qualification requirements, or when alternative manufacturer sourcing is preferred for cost optimization or availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F5900CS is determined by the following mandatory parameters:

Critical Matching Parameters:

• Resistance value: 590 Ohms
• Tolerance: ±1%
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Moisture Sensitivity Level: MSL 1
• RoHS3 Compliance

Allowable Variation:

• Power rating may be equal or higher (0.333W minimum)
• Physical dimensions may vary within package specification tolerances
• Packaging format (bulk vs. Tape & Reel) does not affect electrical substitution

All three substitute parts meet these criteria. AC1210FR-07590RL and CRCW1210590RFKEA provide upgraded power ratings (0.5W) with automotive AEC-Q200 qualification. ERJ-14NF5900U matches the same specifications but carries a "Not For New Designs" status.

Parameter Comparison

Engineering Selection Recommendations

For Active Product Designs: AC1210FR-07590RL (YAGEO) and CRCW1210590RFKEA (Vishay Dale) are both suitable substitutes with Active product status. Both parts provide higher power dissipation capability (0.5W vs. 0.333W) and carry AEC-Q200 automotive qualification, making them appropriate for designs requiring enhanced thermal margin or automotive-grade reliability.

For Automotive Applications: AC1210FR-07590RL and CRCW1210590RFKEA both meet AEC-Q200 qualification standards. CRCW1210590RFKEA offers the highest inventory availability (13465 units) among qualified alternatives.

For Legacy or Existing Designs: ERJ-14NF5900U maintains electrical and thermal compatibility but carries "Not For New Designs" status. This part is suitable only for sustaining production of existing designs or repair applications where the original specification must be maintained.

Inventory Considerations: CRCW1210590RFKEA provides the largest available stock (13465 units), followed by AC1210FR-07590RL (11982 units), making either option preferable for high-volume procurement.

Frequently Asked Questions (FAQ)

Q: Can AC1210FR-07590RL replace RC3225F5900CS in existing designs? A: Yes. AC1210FR-07590RL is electrically and mechanically compatible. The higher power rating (0.5W vs. 0.333W) provides additional thermal margin without affecting circuit performance. Physical dimensions remain within 1210 package tolerances.

Q: What is the difference between the three substitute parts? A: All three substitutes match the critical electrical parameters (590 Ohms, ±1%, 1210 package, thick film, ±100ppm/°C, -55°C to 155°C). AC1210FR-07590RL and CRCW1210590RFKEA are Active products with AEC-Q200 automotive qualification and 0.5W power rating. ERJ-14NF5900U carries "Not For New Designs" status but remains available for legacy applications.

Q: Are there packaging differences between these parts? A: RC3225F5900CS is supplied in bulk packaging. AC1210FR-07590RL, CRCW1210590RFKEA, and ERJ-14NF5900U are supplied in Tape & Reel format. This affects handling and assembly processes but does not impact electrical performance.

Q: Which substitute should be selected for new automotive designs? A: Both AC1210FR-07590RL and CRCW1210590RFKEA carry AEC-Q200 qualification and Active product status. CRCW1210590RFKEA offers superior inventory availability. Either part is appropriate for automotive applications.

Q: Is the RC3225F5900CS still in production? A: Yes, RC3225F5900CS maintains Active product status with 1032 units in current inventory. However, substitute parts with higher power ratings and automotive qualification offer enhanced design flexibility.

Q: Can ERJ-14NF5900U be used in new designs? A: ERJ-14NF5900U carries "Not For New Designs" status and should be reserved for sustaining production of existing designs or repair applications only. AC1210FR-07590RL or CRCW1210590RFKEA are recommended for new design implementations.
