RC3225F5763CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F5763CS is a 576 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1210 (3225 Metric) package format with 0.333W power rating. This component is classified as Active product status and is RoHS3 compliant with MSL 1 moisture sensitivity rating.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit alternative specifications within the same functional parameters. The RC3225F5763CS has been identified with one primary equivalent: the ERJ-14NF5763U from Panasonic Electronic Components.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F5763CS is determined by the following critical parameters:

Primary Substitution Criteria:

• Resistance value: 576 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package format: 1210 (3225 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)

Secondary Consideration:

• Power rating: The substitute may exceed the original 0.333W specification, as higher power ratings are backward compatible in applications not thermally constrained

The ERJ-14NF5763U from Panasonic meets all primary criteria with an elevated power rating of 0.5W (1/2W), making it functionally equivalent for circuits designed within the original 0.333W specification. The substitute maintains identical resistance, tolerance, package dimensions, and temperature characteristics.

Parameter Comparison

Engineering Selection Recommendations

RC3225F5763CS (Samsung Electro-Mechanics) - Primary Selection:

• Active product status ensures continued availability and manufacturing support
• RoHS3 compliant for current regulatory requirements
• Optimal for new designs and long-term production programs
• 964 units in current inventory

ERJ-14NF5763U (Panasonic Electronic Components) - Substitute Selection:

• Not For New Designs status indicates this component is in end-of-life phase
• RoHS non-compliant; unsuitable for applications requiring RoHS certification
• Higher power rating (0.5W vs. 0.333W) provides thermal margin in existing designs
• Automotive AEC-Q200 qualification available if automotive-grade reliability is required
• 2400 units in current inventory
• Suitable only for legacy design support or non-regulated applications

Compliance Consideration: The RC3225F5763CS is the only option for designs requiring RoHS3 compliance. The ERJ-14NF5763U substitute should be used only when RoHS compliance is not a requirement and the design is not intended for new production.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF5763U replace RC3225F5763CS in all applications?

A: Electrical substitution is valid for circuits designed within the original 0.333W power specification. The higher 0.5W rating of the ERJ-14NF5763U does not create functional incompatibility. However, RoHS compliance status differs; verify regulatory requirements before substitution.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF5763U?

A: This designation indicates the component is in end-of-life phase and Panasonic does not recommend its use in new product designs. It may be used for legacy system support or repair applications where supply of the primary component is unavailable.

Q: Are the physical dimensions identical between these parts?

A: Both components use the 1210 (3225 Metric) package. Dimensional variations exist within tolerance: RC3225F5763CS measures 0.126" L x 0.100" W with 0.026" max height; ERJ-14NF5763U measures 0.126" L x 0.098" W with 0.028" max height. These differences are within standard PCB layout tolerances for 1210 components.

Q: What does MSL 1 (Unlimited) moisture sensitivity mean?

A: MSL 1 indicates the component has unlimited shelf life under standard storage conditions and requires no special moisture control during handling, storage, or assembly. Both the main part and substitute share this rating.

Q: Why does the substitute have higher power rating?

A: The ERJ-14NF5763U is rated for 0.5W (1/2W) compared to the RC3225F5763CS at 0.333W (1/3W). This reflects different thermal design margins in the manufacturing process. The higher rating does not affect electrical performance in circuits operating below the original specification.

Q: Is the ERJ-14NF5763U suitable for automotive applications?

A: The ERJ-14NF5763U carries AEC-Q200 automotive qualification. However, its RoHS non-compliant status may restrict use in modern automotive designs requiring environmental compliance. Verify specific automotive program requirements before selection.

Q: What packaging formats are available for these parts?

A: RC3225F5763CS is supplied in standard packaging (format not specified in data). ERJ-14NF5763U is supplied in Tape & Reel (TR) format, suitable for automated assembly processes.
