RC3225F76R8CS Equivalent & Substitute Parts

Part Overview

The RC3225F76R8CS is a 76.8 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1210 (3225 Metric) package format with a power rating of 0.333W (1/3W). This component is classified as Active product status and features moisture-resistant construction suitable for general industrial and commercial applications.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit alternative specifications that maintain functional compatibility within the circuit application.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC3225F76R8CS is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters for Substitution:

• Resistance value: 76.8 Ohms (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 (exact match required)
• Number of Terminations: 2 (exact match required)

Allowable Variation:

• Power rating: Substitute parts may have equal or higher power ratings than the original 0.333W specification, provided all other parameters remain unchanged
• Physical dimensions: Minor variations within standard manufacturing tolerances for the 1210 package are acceptable
• Compliance certifications: Substitute parts must maintain ROHS3 compliance and MSL 1 rating

The ERJ-14NF76R8U from Panasonic Electronic Components qualifies as a substitute based on matching all critical parameters while providing an increased power rating of 0.5W (1/2W).

Parameter Comparison

Engineering Selection Recommendations

RC3225F76R8CS (Samsung Electro-Mechanics): Select this component for new designs and applications requiring active product status with ongoing manufacturer support. The Active product status ensures continued availability and manufacturing consistency. This part is suitable for general industrial and commercial applications with moisture-resistant requirements.

ERJ-14NF76R8U (Panasonic Electronic Components): This substitute part is classified as Not For New Designs, indicating that Panasonic has discontinued active development and support for this component. The ERJ-14NF76R8U is suitable only for replacement, repair, or legacy system maintenance where the original RC3225F76R8CS is unavailable. The increased power rating of 0.5W provides additional thermal margin compared to the original 0.333W specification. This part includes AEC-Q200 automotive qualification, which exceeds the requirements of the original component.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-14NF76R8U replace the RC3225F76R8CS in all applications?

A: The ERJ-14NF76R8U is electrically and mechanically compatible with the RC3225F76R8CS for applications where the original 0.333W power rating is sufficient. The higher 0.5W power rating of the substitute does not create incompatibility. However, the Not For New Designs status of the ERJ-14NF76R8U makes it unsuitable for new product development.

Q: What is the significance of the power rating difference between these parts?

A: The RC3225F76R8CS has a power rating of 0.333W, while the ERJ-14NF76R8U has a power rating of 0.5W. A substitute with equal or higher power rating maintains compatibility because it can safely dissipate the same or greater thermal load. The higher rating does not affect electrical performance in the circuit.

Q: Are there physical dimension differences between these parts?

A: Both parts use the 1210 (3225 Metric) package format. Minor dimensional variations exist within standard manufacturing tolerances: the RC3225F76R8CS has a maximum seated height of 0.026" (0.66mm), while the ERJ-14NF76R8U has a maximum seated height of 0.028" (0.70mm). These variations are within acceptable tolerances for standard PCB assembly processes.

Q: What does the Not For New Designs status mean for the ERJ-14NF76R8U?

A: Not For New Designs indicates that Panasonic has discontinued active development and support for this component line. New product designs should use the RC3225F76R8CS or other Active status alternatives. The ERJ-14NF76R8U remains available for replacement and repair applications only.

Q: Are both parts RoHS compliant?

A: Yes, both the RC3225F76R8CS and ERJ-14NF76R8U are ROHS3 compliant and have Moisture Sensitivity Level 1 (Unlimited), indicating they meet current environmental and regulatory requirements.

Q: What is the difference between the RC series and ERJ-14N series designations?

A: RC is the Samsung Electro-Mechanics series designation, while ERJ-14N is the Panasonic Electronic Components series designation. These are manufacturer-specific product line identifiers and do not affect functional compatibility when all electrical and mechanical parameters match.
