RC3225J240CS Equivalent & Substitute Parts

Part Overview

The RC3225J240CS is a 24 Ohm ±5% 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 ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and is currently in active production status with 710 units available in inventory.

Substitute parts are identified to provide alternatives with improved electrical specifications, enhanced power ratings, or alternative manufacturer sourcing while maintaining mechanical and thermal compatibility within the 1210 package footprint.

Substitute Part Grouping Explanation

Substitution of the RC3225J240CS is permissible with parts meeting the following criteria:

Core Compatibility Requirements:

• Resistance value: 24 Ohms (exact match)
• Package format: 1210 (3225 Metric) (exact match)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C (minimum)
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS3 Compliance

Allowable Parameter Variations:

• Tolerance: ±5% or tighter (±1% acceptable as upgrade)
• Power Rating: 0.333W or higher (0.5W acceptable as upgrade)
• Manufacturer: Alternative qualified manufacturers permitted
• Packaging Format: Tape & Reel acceptable for equivalent functionality

The three substitute parts listed (RC1210JR-0724RL, RC1210FR-0724RL, AC1210FR-0724RL) all satisfy these core compatibility requirements while offering improved tolerance and power rating specifications.

Parameter Comparison

Engineering Selection Recommendations

RC1210JR-0724RL (YAGEO): This substitute maintains the ±5% tolerance specification of the main part while providing increased power rating (0.5W vs. 0.333W). All electrical and thermal parameters remain identical. This part is suitable for direct substitution where tolerance and power specifications are not limiting factors. ROHS3 compliance and MSL 1 rating are maintained.

RC1210FR-0724RL (YAGEO): This substitute offers improved tolerance (±1% vs. ±5%) and increased power rating (0.5W vs. 0.333W). All other electrical and thermal parameters match the main part. This part is suitable for applications requiring tighter tolerance control. ROHS3 compliance and MSL 1 rating are maintained.

AC1210FR-0724RL (YAGEO): This substitute provides the same electrical improvements as RC1210FR-0724RL (±1% tolerance, 0.5W power rating) with the addition of Automotive AEC-Q200 qualification. This part is suitable for automotive applications or where automotive-grade component qualification is required. ROHS3 compliance and MSL 1 rating are maintained.

All three substitute parts are mechanically compatible with the 1210 package footprint and maintain identical thermal operating ranges and moisture sensitivity characteristics.

Frequently Asked Questions (FAQ)

Q: Can RC1210JR-0724RL be used as a direct replacement for RC3225J240CS?

A: Yes. RC1210JR-0724RL maintains the same 24 Ohm resistance, ±5% tolerance, and identical thermal and moisture specifications. The increased power rating (0.5W vs. 0.333W) provides additional thermal margin. Both parts are housed in the 1210 package and are mechanically and electrically compatible.

Q: What is the difference between RC1210FR-0724RL and RC1210JR-0724RL?

A: Both parts are manufactured by YAGEO in the 1210 package with 24 Ohm resistance and 0.5W power rating. The primary difference is tolerance: RC1210FR-0724RL offers ±1% tolerance while RC1210JR-0724RL offers ±5% tolerance. Selection depends on tolerance requirements of the application.

Q: When should AC1210FR-0724RL be selected over other substitutes?

A: AC1210FR-0724RL should be selected when Automotive AEC-Q200 qualification is required. This part carries automotive-grade certification in addition to the electrical and thermal specifications common to all three substitutes. It is suitable for automotive and safety-critical applications.

Q: Are all substitute parts available in the same packaging format as the main part?

A: The main part RC3225J240CS is supplied in bulk packaging. All three substitute parts are supplied in Tape & Reel (TR) format. This difference affects handling and assembly processes but does not impact electrical or mechanical compatibility.

Q: Do the substitute parts maintain the same moisture sensitivity rating?

A: Yes. All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity rating, identical to the main part. This indicates no moisture-related handling restrictions during storage or assembly.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All parts share identical 1210 package dimensions and footprint specifications. They are mechanically and electrically interchangeable on PCB layouts designed for the RC3225J240CS.

Q: What is the temperature coefficient specification for all parts?

A: All parts, including the main part and all substitutes, have a temperature coefficient of ±100ppm/°C and operate across the identical temperature range of -55°C to 155°C.
