RC3225F4871CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F4871CS is a 4.87 kOhms ±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 maintains Active product status and is RoHS3 compliant with MSL 1 moisture sensitivity rating.

Equivalent and substitute parts are identified when components share identical electrical specifications (resistance value, tolerance, temperature coefficient) and compatible mechanical packaging, while potentially differing in power rating, product lifecycle status, or application-specific certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F4871CS is determined by the following criteria:

Mandatory Matching Parameters:

• Resistance value: 4.87 kOhms
• Tolerance: ±1%
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Compatible Variation Parameters:

• Power rating: Equal or greater than 0.333W
• Packaging format: Tape & Reel or bulk acceptable
• Product status: Active or Not For New Designs
• Application certifications: May include automotive (AEC-Q200) or industrial qualifications

The ERJ-14NF4871U from Panasonic Electronic Components qualifies as a substitute based on matching all mandatory electrical parameters. This part provides 0.5W (1/2W) power rating, exceeding the RC3225F4871CS requirement, and maintains identical resistance, tolerance, temperature coefficient, and operating temperature specifications within the same 1210 package footprint.

Parameter Comparison

Engineering Selection Recommendations

RC3225F4871CS Selection Criteria: The RC3225F4871CS maintains Active product status, making it the preferred choice for new design implementations. This component is suitable for general industrial and consumer applications requiring standard moisture resistance without automotive qualification requirements.

ERJ-14NF4871U Selection Criteria: The ERJ-14NF4871U carries "Not For New Designs" status, indicating this part is in end-of-life phase. However, it remains available for legacy system maintenance, repair, and replacement applications. The higher 0.5W power rating provides additional thermal margin compared to the RC3225F4871CS specification. The AEC-Q200 automotive qualification indicates this part meets automotive reliability standards, making it suitable for automotive aftermarket or industrial retrofit applications where legacy component compatibility is required.

Both parts maintain RoHS3 compliance and MSL 1 moisture sensitivity rating, ensuring compatibility with standard PCB assembly processes and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF4871U directly replace RC3225F4871CS in existing designs?

A: Yes. Both components share identical electrical specifications (4.87 kOhms ±1%, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range) and compatible 1210 package footprints. The ERJ-14NF4871U provides higher power rating (0.5W vs. 0.333W), which does not create compatibility issues. Dimensional variations (height 0.028" vs. 0.026") are within standard PCB assembly tolerances.

Q: Why is ERJ-14NF4871U marked "Not For New Designs"?

A: This designation indicates the part is in end-of-life status with Panasonic. New product development should prioritize the RC3225F4871CS or equivalent active-status alternatives. The ERJ-14NF4871U remains suitable for maintenance, repair, and legacy system support.

Q: Are there packaging differences between these parts?

A: The RC3225F4871CS is supplied in standard packaging format. The ERJ-14NF4871U is supplied in Tape & Reel (TR) format. Both are compatible with automated PCB assembly equipment. Tape & Reel format is standard for high-volume production environments.

Q: Do compliance certifications differ between these parts?

A: Both parts are RoHS3 compliant and REACH unaffected. The ERJ-14NF4871U includes AEC-Q200 automotive qualification, while the RC3225F4871CS specifies moisture resistance. AEC-Q200 qualification does not restrict use in non-automotive applications.

Q: What is the significance of MSL 1 rating for both parts?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake-out requirements. Both components can be stored and handled under standard warehouse conditions without special moisture control procedures.
