RC3225F7682CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F7682CS is a 76.8 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 with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with MSL 1 rating.

Substitute components become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit higher power ratings or alternative certifications such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the RC3225F7682CS is based on the following mandatory alignment criteria:

Critical Parameters (Must Match):

• Resistance value: 76.8 kOhms
• Tolerance: ±1% (tighter tolerances acceptable)
• Package format: 1210 (3225 Metric)
• Operating temperature range: -55°C to 155°C minimum
• Composition: Thick film construction

Acceptable Variation Parameters:

• Power rating: Substitute must equal or exceed 0.333W
• Temperature coefficient: ±100ppm/°C or better
• RoHS compliance: ROHS3 or equivalent
• Moisture sensitivity: MSL 1 acceptable

The ERJ-14NF7682U from Panasonic Electronic Components qualifies as a direct substitute based on matching resistance, tolerance, package, temperature range, and composition. The higher power rating (0.5W vs. 0.333W) provides additional thermal margin and does not create incompatibility. Both components share identical temperature coefficient specifications and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Primary Component Selection: The RC3225F7682CS maintains Active product status and is the preferred choice for new design implementations. This component is currently in full production with established supply channels and represents the baseline specification for this resistance and power rating combination.

Substitute Component Consideration: The ERJ-14NF7682U from Panasonic Electronic Components serves as a functional equivalent when RC3225F7682CS availability is constrained. The substitute meets all critical electrical parameters and maintains identical thermal and regulatory compliance profiles. The higher power rating (0.5W vs. 0.333W) introduces no compatibility issues and provides additional thermal headroom in the application circuit.

Product Status Impact: The ERJ-14NF7682U carries "Not For New Designs" status, indicating Panasonic has transitioned this part to mature production phase. This designation does not affect substitution validity for existing designs or when supply of the primary part is unavailable. However, for new design initiatives, the RC3225F7682CS should be the first selection due to its Active status.

Certification Advantage: The ERJ-14NF7682U includes AEC-Q200 automotive qualification, which exceeds the standard industrial compliance of the primary part. This additional certification permits use in automotive applications where the RC3225F7682CS may not be specified.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF7682U replace RC3225F7682CS in existing circuit designs?

A: Yes. Both components share identical resistance value (76.8 kOhms), tolerance (±1%), package format (1210), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The higher power rating of the substitute (0.5W vs. 0.333W) does not create incompatibility and provides additional thermal margin.

Q: What does "Not For New Designs" mean for the ERJ-14NF7682U?

A: This designation indicates the part has transitioned to mature production status at Panasonic. The component remains fully functional and available for procurement. New design initiatives should prioritize the RC3225F7682CS due to its Active status, but the substitute remains valid for replacement and redesign scenarios.

Q: Are the physical dimensions compatible between these two parts?

A: Both components use the 1210 (3225 Metric) package format. Dimensions are nearly identical: RC3225F7682CS measures 3.20mm L × 2.55mm W with 0.66mm maximum seated height; ERJ-14NF7682U measures 3.20mm L × 2.50mm W with 0.70mm maximum seated height. These minor variations fall within standard PCB footprint tolerances and present no placement or assembly issues.

Q: Does the substitute part require different handling or storage procedures?

A: No. Both components carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating unlimited shelf life under standard storage conditions. Handling, storage, and reflow procedures remain identical.

Q: Can the ERJ-14NF7682U be used in automotive applications where RC3225F7682CS is specified?

A: The ERJ-14NF7682U includes AEC-Q200 automotive qualification, which permits its use in automotive applications. However, design specifications should be reviewed to confirm whether automotive certification is required or merely beneficial. If the original specification does not mandate automotive qualification, both parts are functionally equivalent.

Q: What is the impact of the higher power rating on circuit performance?

A: The 0.5W rating of the ERJ-14NF7682U versus the 0.333W rating of the RC3225F7682CS affects only thermal dissipation capability. In applications where the resistor dissipates less than 0.333W, both parts operate identically. The higher rating provides additional safety margin and reduces junction temperature, potentially extending component life in high-dissipation scenarios.

Q: Are there packaging differences between these components?

A: The RC3225F7682CS is supplied in standard packaging format. The ERJ-14NF7682U is supplied in Tape & Reel (TR) format. This difference affects procurement and assembly processes but does not impact electrical or mechanical compatibility. Tape & Reel format is standard for automated assembly operations.
