RC3225F823CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F823CS is an 82 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.333W (1/3W) power dissipation in a 1210 (3225 Metric) package. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). The part is specified for applications requiring precision resistive elements across industrial and commercial temperature ranges. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained within the allowed parameter tolerances for this resistor category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F823CS is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters (Non-Negotiable):

• Resistance value: 82 kOhms
• Tolerance: ±1%
• Package / Case: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS3 Compliance status
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Power Rating: Substitute parts may exceed the original 0.333W specification, provided the higher power rating does not compromise mechanical fit or thermal characteristics within the 1210 package envelope
• Physical dimensions: Minor variations within the 1210 package standard are permissible
• Packaging format: Original part uses standard packaging; substitutes may use alternative packaging formats (Tape & Reel) without affecting functional compatibility

The RC1210FR-0782KL from YAGEO qualifies as a substitute because it maintains all critical matching parameters while providing an increased power rating of 0.5W (1/2W), which represents an upgrade in power handling capability without electrical or mechanical incompatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (RC3225F823CS): Select the Samsung Electro-Mechanics RC3225F823CS when the original design specification explicitly requires a 0.333W (1/3W) power rating and Samsung sourcing is mandated by procurement or supply chain requirements. This part maintains Active product status with established inventory availability (780 Pcs).

Substitute Part Selection (RC1210FR-0782KL): The YAGEO RC1210FR-0782KL is functionally equivalent and mechanically compatible for direct substitution in applications where the original 0.333W power rating is not a limiting constraint. The increased 0.5W power rating provides additional thermal margin without introducing electrical incompatibility. This substitute is suitable when:

• Supply continuity of the Samsung part is interrupted
• YAGEO sourcing aligns with procurement strategy
• The application circuit can accommodate the higher power rating specification
• Tape & Reel packaging format is acceptable for assembly processes

Both parts maintain identical RoHS3 compliance, REACH status, and MSL 1 rating, ensuring regulatory and environmental compatibility across equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can the RC1210FR-0782KL (0.5W) directly replace the RC3225F823CS (0.333W) in the same circuit?

A: Yes. The RC1210FR-0782KL is electrically and mechanically compatible for direct substitution. The higher power rating (0.5W vs. 0.333W) represents increased thermal capacity and does not create incompatibility. The substitute will operate within the same electrical parameters (82 kOhms ±1%, ±100ppm/°C, -55°C ~ 155°C).

Q: Are there dimensional differences between these two parts?

A: Both parts conform to the 1210 (3225 Metric) package standard. Minor dimensional variations exist within standard tolerance: RC3225F823CS measures 3.20mm x 2.55mm; RC1210FR-0782KL measures 3.10mm x 2.60mm. These differences fall within 1210 package specifications and do not affect PCB footprint compatibility or assembly processes.

Q: What is the significance of the different packaging formats?

A: The RC3225F823CS uses standard packaging, while the RC1210FR-0782KL is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and does not affect component performance. Selection depends on assembly equipment capability and procurement volume requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the RC3225F823CS and RC1210FR-0782KL are ROHS3 Compliant, REACH Unaffected, classified as EAR99, and carry MSL 1 (Unlimited) moisture sensitivity rating. Regulatory and environmental compliance is equivalent.

Q: What is the temperature coefficient specification, and is it identical between parts?

A: Both parts specify ±100ppm/°C temperature coefficient across the operating range of -55°C ~ 155°C. This parameter is identical and ensures equivalent thermal stability in temperature-sensitive applications.

Q: Can I use the RC1210FR-0782KL in a design originally specified for the RC3225F823CS without circuit redesign?

A: Yes, provided the original design does not explicitly require the 0.333W power limitation. The substitute maintains all critical electrical parameters (resistance, tolerance, temperature coefficient, operating range) and mechanical compatibility (1210 package, footprint). No circuit redesign is necessary for functional equivalence.
