RC3225F6983CS Equivalent & Substitute Parts

Part Overview

The RC3225F6983CS is a 698 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 classified as Active product status and carries ROHS3 compliance with Moisture Sensitivity Level 1 (unlimited shelf life).

Substitute parts are necessary when the primary component becomes unavailable, when design requirements shift toward higher power ratings or automotive-grade specifications, or when supply chain optimization requires alternative sourcing from qualified manufacturers.

Substitute Part Grouping Explanation

Substitution of the RC3225F6983CS is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Resistance value: 698 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 to 155°C (exact match required)
• Number of terminations: 2 (exact match required)

Allowable Variation Parameters:

• Power rating: Equal to or greater than 0.333W
• Manufacturer: Different manufacturer acceptable if all critical parameters match
• Packaging format: May differ (bulk, tape & reel, etc.)
• Compliance certifications: May include additional certifications beyond ROHS3

The ERJ-14NF6983U from Panasonic Electronic Components qualifies as a substitute because it maintains all critical matching parameters while offering an increased power rating of 0.5W (1/2W) and automotive AEC-Q200 certification.

Parameter Comparison

Engineering Selection Recommendations

RC3225F6983CS (Samsung Electro-Mechanics): Select this part for new designs requiring ROHS3 compliance and active product status support. The component is suitable for general-purpose applications with 0.333W power dissipation requirements. Active product status ensures long-term availability and manufacturer support.

ERJ-14NF6983U (Panasonic Electronic Components): This substitute is applicable when higher power dissipation (0.5W) is required within the same package footprint and resistance value. The AEC-Q200 automotive qualification makes this part suitable for automotive-grade applications. However, the product status is classified as "Not For New Designs," indicating this part is in mature or end-of-life phase. The RoHS non-compliant status requires evaluation against specific regulatory requirements for the target application.

Selection between these parts depends on compliance requirements, power dissipation needs, and product lifecycle phase of the target application.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF6983U replace RC3225F6983CS in all applications?

A: The ERJ-14NF6983U is electrically and mechanically compatible with RC3225F6983CS for applications requiring equal or lower power dissipation. The higher power rating (0.5W vs. 0.333W) does not create incompatibility. However, the RoHS non-compliant status of the Panasonic part must be evaluated against application-specific regulatory requirements.

Q: What are the physical differences between these parts?

A: Both parts use the 1210 (3225 Metric) package. The RC3225F6983CS measures 0.126" L x 0.100" W with a maximum seated height of 0.026". The ERJ-14NF6983U measures 0.126" L x 0.098" W with a maximum seated height of 0.028". These dimensional variations are within typical PCB layout tolerances for 1210 package components.

Q: Why is the Panasonic part marked "Not For New Designs"?

A: Product status "Not For New Designs" indicates the manufacturer is transitioning this part toward end-of-life. While the part remains available and functional, new product designs should prioritize the RC3225F6983CS or evaluate alternative long-term sources to ensure supply continuity.

Q: Are there compliance differences between these parts?

A: The RC3225F6983CS is ROHS3 compliant, while the ERJ-14NF6983U is RoHS non-compliant. The Panasonic part carries AEC-Q200 automotive certification, which the Samsung part does not. Application requirements determine which compliance profile is necessary.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes, both parts are mechanically and electrically interchangeable on PCBs designed for the 1210 package format. The minor dimensional differences do not affect standard PCB layout and assembly processes.

Q: What is the significance of the ±100ppm/°C temperature coefficient?

A: The temperature coefficient indicates the resistance value changes by approximately 100 parts per million for each degree Celsius change in operating temperature. Both parts share this specification, ensuring equivalent thermal stability across the -55°C to 155°C operating range.
