RC3225F240CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F240CS is a 24 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.333W (1/3W) power dissipation in a 1210 (3225 Metric) surface mount package. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and performance envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F240CS is determined by strict adherence to the following criteria:

Mandatory Matching Parameters:

• Resistance value: 24 Ohms
• Tolerance: ±1%
• Package footprint: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS3 compliance

Allowable Variation:

• Power rating: Substitute parts with equal or higher power dissipation (0.5W or greater) are functionally compatible, as they maintain or exceed the thermal performance envelope of the original 0.333W specification.

Both identified substitute parts (AC1210FR-0724RL and RC1210FR-0724RL) meet all mandatory parameters and feature upgraded power ratings of 0.5W (1/2W), providing enhanced thermal margin in the same physical package.

Parameter Comparison

Engineering Selection Recommendations

AC1210FR-0724RL (YAGEO): This substitute incorporates AEC-Q200 automotive qualification in addition to standard thick film construction. Selection is appropriate for applications requiring automotive-grade reliability and enhanced power dissipation (0.5W). The automotive certification provides additional qualification documentation for regulated environments.

RC1210FR-0724RL (YAGEO): This substitute provides equivalent electrical performance with upgraded power rating (0.5W) in standard thick film construction without automotive-specific qualification. Selection is appropriate for general industrial and commercial applications requiring higher thermal margin than the original 0.333W specification.

Both substitutes maintain identical electrical characteristics (24 Ohms ±1%, ±100ppm/°C temperature coefficient) and thermal operating range (-55°C ~ 155°C). All three parts carry Active product status and full RoHS3 compliance. Physical dimensions vary slightly within acceptable tolerances for 1210 package footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can AC1210FR-0724RL or RC1210FR-0724RL be used as direct replacements for RC3225F240CS?

A: Yes. Both substitute parts maintain identical resistance value (24 Ohms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and package footprint (1210 / 3225 Metric). The upgraded power rating (0.5W versus 0.333W) provides enhanced thermal performance without affecting electrical compatibility.

Q: What is the difference between AC1210FR-0724RL and RC1210FR-0724RL?

A: AC1210FR-0724RL includes AEC-Q200 automotive qualification; RC1210FR-0724RL does not. Both share identical electrical specifications and power rating. Selection depends on application requirements for automotive-grade certification.

Q: Are there physical dimension differences between the main part and substitutes?

A: Minor dimensional variations exist within the 1210 package specification. Main part: 0.126" L × 0.100" W (3.20mm × 2.55mm), height 0.026" (0.66mm). Substitutes: 0.122" L × 0.102" W (3.10mm × 2.60mm), height 0.024" (0.60mm). These variations remain within standard 1210 footprint tolerances and do not affect PCB layout compatibility.

Q: Do all three parts meet RoHS3 compliance?

A: Yes. RC3225F240CS, AC1210FR-0724RL, and RC1210FR-0724RL are all ROHS3 Compliant with REACH Unaffected status.

Q: What is the moisture sensitivity level for these parts?

A: All three parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What packaging formats are available?

A: RC3225F240CS is supplied in bulk packaging. AC1210FR-0724RL and RC1210FR-0724RL are supplied in Tape & Reel (TR) format, suitable for automated assembly processes.
