RC3225F820CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F820CS is an 82 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1210 (3225 Metric) package format. This component delivers 0.333W (1/3W) power dissipation with moisture-resistant construction and operates across the -55°C to 155°C temperature range. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are identified to support procurement flexibility, inventory optimization, and supply chain continuity while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC3225F820CS are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Parameters (Must Match):

• Resistance value: 82 Ohms
• Tolerance: ±1%
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package / Case: 1210 (3225 Metric)
• Composition: Thick Film
• Number of Terminations: 2
• Moisture Resistant construction

Compliance Parameters (Must Match or Exceed):

• RoHS3 Compliant
• MSL 1 (Unlimited)

Power Rating Consideration: Substitute parts with equal or higher power ratings (0.333W or greater) are acceptable. The identified substitutes feature 0.5W (1/2W) power ratings, which exceed the original specification and provide enhanced thermal margin without affecting circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

RC1210FR-0782RL (YAGEO): This substitute maintains full electrical and mechanical compatibility with the RC3225F820CS. Both components share identical resistance, tolerance, temperature coefficient, and operating temperature specifications. The RC1210FR-0782RL provides increased power dissipation capacity (0.5W versus 0.333W), delivering superior thermal performance in the same 1210 package footprint. ROHS3 compliance and MSL 1 rating are maintained. This part is suitable for direct substitution in applications where the original specification does not require the lower power rating.

AC1210FR-0782RL (YAGEO): This substitute provides all electrical and mechanical compatibility parameters identical to RC1210FR-0782RL, with the addition of AEC-Q200 automotive qualification. The AC1210FR-0782RL is appropriate for applications requiring automotive-grade components or where enhanced reliability documentation is mandated by design specifications. The 0.5W power rating and identical electrical characteristics ensure functional equivalence.

Both substitutes are qualified for direct replacement based on matching resistance, tolerance, temperature coefficient, operating temperature range, package format, composition, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can RC1210FR-0782RL or AC1210FR-0782RL be used as direct replacements for RC3225F820CS?

A: Yes. Both YAGEO parts are direct substitutes. They match all critical electrical parameters (82 Ohms ±1%, ±100ppm/°C, -55°C to 155°C), mechanical specifications (1210 package, thick film, 2 terminations), and compliance requirements (ROHS3, MSL 1). The higher power rating (0.5W) is compatible with circuits designed for the original 0.333W specification.

Q: What is the difference between RC1210FR-0782RL and AC1210FR-0782RL?

A: Both parts are electrically and mechanically identical. The AC1210FR-0782RL includes AEC-Q200 automotive qualification, making it suitable for automotive applications or designs requiring automotive-grade component documentation. Select AC1210FR-0782RL when automotive compliance is specified; otherwise, RC1210FR-0782RL is functionally equivalent.

Q: Does the higher power rating (0.5W) of the substitute parts affect circuit performance?

A: No. A higher power rating does not degrade circuit performance. The 0.5W rating indicates the component can safely dissipate more power than the original 0.333W specification. In circuits operating within the original power budget, the substitute parts perform identically while providing additional thermal margin.

Q: Are the physical dimensions of the substitute parts compatible with the original PCB layout?

A: Yes. All three parts use the 1210 (3225 Metric) package format with compatible footprints. Dimensional variations (RC3225F820CS: 3.20mm x 2.55mm; substitutes: 3.10mm x 2.60mm) are within standard PCB design tolerances and do not require layout modifications.

Q: What compliance certifications apply to all three parts?

A: All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings. The AC1210FR-0782RL additionally holds AEC-Q200 automotive qualification.
