RC3225F4531CS Equivalent & Substitute Parts

Part Overview

The RC3225F4531CS is a 4.53 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 production status with 1114 units available in new original inventory.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility exist, enabling direct replacement in circuit designs while maintaining performance requirements and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F4531CS is determined by the following critical parameters:

Electrical Specifications:

• Resistance value: 4.53 kOhms
• Tolerance: ±1%
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Specifications:

• Package format: 1210 (3225 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Requirements:

• RoHS3 Compliant status
• Moisture Sensitivity Level 1 (Unlimited)

The ERJ-P14F4531U from Panasonic Electronic Components meets all critical electrical and mechanical parameters. While the substitute part features a higher power rating (0.5W versus 0.333W), this represents an uprated capability that does not restrict substitution in applications designed for the original part's specifications. Both components share identical resistance, tolerance, temperature coefficient, operating temperature range, package format, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

RC3225F4531CS (Samsung Electro-Mechanics):

• Primary selection for applications requiring the specified 0.333W power rating
• Active production status with established supply chain
• ROHS3 and REACH compliance confirmed
• Moisture Sensitivity Level 1 suitable for standard storage and handling conditions

ERJ-P14F4531U (Panasonic Electronic Components):

• Direct substitute with identical electrical performance
• Higher power rating (0.5W) provides thermal margin in power-dissipation-sensitive applications
• AEC-Q200 automotive qualification available
• Pulse withstanding capability provides additional robustness
• ROHS3 and REACH compliance confirmed
• Moisture Sensitivity Level 1 suitable for standard storage and handling conditions

Both parts are active products with full compliance certifications. Selection between them depends on application-specific requirements regarding power dissipation margin, automotive qualification needs, and supplier availability.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-P14F4531U replace the RC3225F4531CS in all applications?

A: The ERJ-P14F4531U is electrically and mechanically compatible with the RC3225F4531CS. Both components share identical resistance (4.53 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and package format (1210). The substitute part's higher power rating (0.5W versus 0.333W) does not restrict substitution in designs specified for the original part.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. The RC3225F4531CS measures 0.126" L x 0.100" W with a maximum seated height of 0.026". The ERJ-P14F4531U measures 0.126" L x 0.098" W with a maximum seated height of 0.028". These differences are within standard 1210 package tolerances and do not affect PCB layout compatibility.

Q: Do both parts meet the same compliance standards?

A: Both the RC3225F4531CS and ERJ-P14F4531U are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements.

Q: What is the significance of the ERJ-P14F4531U's AEC-Q200 rating?

A: AEC-Q200 is an automotive qualification standard. The ERJ-P14F4531U's AEC-Q200 certification indicates suitability for automotive applications. This certification is not present on the RC3225F4531CS. Selection of the Panasonic part is appropriate when automotive-grade components are specified.

Q: How do the packaging formats differ?

A: The RC3225F4531CS is supplied in standard packaging format. The ERJ-P14F4531U is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume automated assembly operations and does not affect component performance or compatibility.

Q: Are the temperature coefficients identical?

A: Both parts feature a temperature coefficient of ±100ppm/°C and operate across the identical temperature range of -55°C to 155°C. Temperature stability performance is equivalent between the two components.
