RC3225F7680CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F7680CS is a 768 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.333W (1/3W) in a 1210 (3225 Metric) 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, enabling direct replacement in circuit designs where the main part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F7680CS is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 768 Ohms
• Tolerance: ±1%
• Package / Case: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS3 Compliance: Required
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: Substitute parts may exceed the 0.333W specification, provided the package footprint and all other electrical parameters remain identical. Higher power ratings do not compromise circuit compatibility in applications requiring 0.333W or less.

The identified substitute ERJ-14NF7680U meets all mandatory parameters with an increased power rating of 0.5W (1/2W), making it electrically and mechanically compatible for direct replacement applications.

Engineering Selection Recommendations

RC3225F7680CS (Main Part):

• Product Status: Active
• Recommended for new designs requiring Samsung Electro-Mechanics sourcing or existing designs currently specified with this part number
• Full compliance with RoHS3 and REACH regulations
• Moisture Sensitivity Level 1 provides unlimited shelf life without special storage requirements

ERJ-14NF7680U (Substitute Part):

• Product Status: Not For New Designs
• Suitable for replacement in existing applications where RC3225F7680CS becomes unavailable
• Includes AEC-Q200 automotive qualification, providing additional reliability assurance for automotive and high-reliability applications
• Higher power rating (0.5W vs. 0.333W) offers thermal margin in applications operating near maximum power dissipation limits
• Panasonic sourcing provides alternative supply chain option
• Full compliance with RoHS3 and REACH regulations

Selection between these parts should be based on availability, supply chain strategy, and whether automotive-grade qualification (AEC-Q200) is required for the application.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF7680U replace RC3225F7680CS in all applications?

A: Yes, ERJ-14NF7680U is electrically and mechanically compatible for direct replacement. The higher power rating (0.5W vs. 0.333W) does not create incompatibility; it provides additional thermal capacity. Dimensional variations (width 0.098" vs. 0.100", height 0.028" vs. 0.026") are within acceptable PCB layout tolerances for 1210 package footprints.

Q: Why is ERJ-14NF7680U marked "Not For New Designs"?

A: This designation reflects Panasonic's product lifecycle status, not a technical limitation. The part remains fully functional and compliant. New designs may use this part if supply chain or application-specific requirements (such as AEC-Q200 automotive qualification) justify the selection.

Q: Are there dimensional concerns with the substitute part?

A: Dimensional differences are minimal and within standard PCB design tolerances. Length remains 0.126" (3.20mm). Width variation of 0.002" (0.05mm) and height variation of 0.002" (0.04mm) do not affect standard 1210 footprint compatibility or reflow soldering processes.

Q: Does the higher power rating of ERJ-14NF7680U affect circuit performance?

A: No. Power rating indicates maximum dissipation capability. In applications requiring 0.333W or less, the 0.5W-rated substitute operates identically to the main part. The higher rating provides thermal margin without altering electrical behavior.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RC3225F7680CS and ERJ-14NF7680U are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: Moisture Sensitivity Level 1 indicates the component requires no special moisture control during storage or handling. Both parts can be stored and handled under standard warehouse conditions without desiccant packaging or time-limited shelf life restrictions.

Q: Can these parts be used interchangeably in automotive applications?

A: RC3225F7680CS can be used in automotive applications. ERJ-14NF7680U includes explicit AEC-Q200 automotive qualification, making it the preferred choice for automotive designs requiring certified components. Both meet the same electrical and environmental specifications.
