RC3225F3013CS Equivalent & Substitute Parts

Part Overview

The RC3225F3013CS is a 301 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 is currently in Active product status with 1050 units available in new original inventory.

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 RC3225F3013CS is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 301 kOhms
• Tolerance: ±1%
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variation Parameters:

• Power rating: Substitute parts may have equal or higher power dissipation ratings
• Physical dimensions: Minor variations within supplier device package specifications are acceptable
• Packaging format: Original part uses standard packaging; substitutes may use alternative packaging configurations

The ERJ-14NF3013U from Panasonic Electronic Components qualifies as a substitute based on matching all mandatory parameters while providing a higher power rating of 0.5W (1/2W) compared to the original 0.333W specification.

Parameter Comparison

Engineering Selection Recommendations

RC3225F3013CS (Samsung Electro-Mechanics): Select this part for new designs and applications requiring active product status with ongoing manufacturer support. The component is ROHS3 compliant and carries unlimited moisture sensitivity rating, suitable for standard industrial and commercial applications.

ERJ-14NF3013U (Panasonic Electronic Components): This substitute is applicable for replacement and repair scenarios where the original Samsung component is unavailable. The part carries "Not For New Designs" status, indicating it is maintained for legacy support only. The Panasonic component includes AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components. The higher power rating of 0.5W provides thermal margin over the original 0.333W specification. Both components maintain identical electrical parameters, temperature performance, and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF3013U be used as a direct replacement for RC3225F3013CS?

A: Yes. Both components share identical resistance value (301 kOhms), tolerance (±1%), package format (1210), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and regulatory compliance (ROHS3, MSL 1). The ERJ-14NF3013U provides higher power dissipation (0.5W versus 0.333W), which is acceptable for substitution purposes.

Q: What is the significance of the "Not For New Designs" status on the Panasonic part?

A: This designation indicates the ERJ-14NF3013U is maintained by Panasonic for existing customer support and legacy applications only. New product designs should prioritize the RC3225F3013CS or other components with Active status. The substitute is appropriate for repair, maintenance, and replacement of existing assemblies.

Q: Are there physical dimension differences between these parts?

A: Minor dimensional variations exist within acceptable tolerances. RC3225F3013CS dimensions are 0.126" L x 0.100" W (3.20mm x 2.55mm) with maximum seated height of 0.026" (0.66mm). ERJ-14NF3013U dimensions are 0.126" L x 0.098" W (3.20mm x 2.50mm) with maximum seated height of 0.028" (0.70mm). These variations remain within standard 1210 package specifications and do not affect PCB layout compatibility.

Q: What packaging formats are available for these components?

A: RC3225F3013CS is supplied in standard packaging configuration. ERJ-14NF3013U is available in Tape & Reel (TR) format, which is standard for high-volume manufacturing and automated assembly processes.

Q: Do both parts meet the same regulatory and compliance requirements?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0030. Both carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: What is the difference between the "Moisture Resistant" feature of Samsung and "Automotive AEC-Q200" feature of Panasonic?

A: These represent different qualification frameworks. The Samsung component emphasizes moisture resistance as a material property. The Panasonic component carries AEC-Q200 automotive qualification, which encompasses comprehensive reliability testing including moisture resistance, temperature cycling, and failure rate validation per automotive industry standards. Both provide equivalent moisture protection; AEC-Q200 represents a broader qualification scope.
