RC3225F9760CS Equivalent & Substitute Parts

Part Overview

The RC3225F9760CS is a 976 Ohm ±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 is designed for moisture-resistant applications across an operating temperature range of -55°C to 155°C. The part maintains Active product status with 1140 units currently in stock.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit alternative manufacturers that meet or exceed the electrical and mechanical specifications of the original part.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F9760CS is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 976 Ohms
• Tolerance: ±1%
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Power Rating: Substitute parts may have equal or higher power ratings (0.333W or greater)
• Physical dimensions: Minor variations within package specification tolerances are acceptable
• Packaging format: Original part uses standard packaging; substitutes may use alternative packaging formats (Tape & Reel)
• Product Status: Substitutes may have different product status classifications
• Certifications: Substitutes may include additional certifications (such as AEC-Q200) beyond the base requirements

The ERJ-14NF9760U from Panasonic Electronic Components qualifies as a direct substitute based on matching all mandatory parameters while providing a higher power rating of 0.5W (1/2W) and automotive-grade AEC-Q200 certification.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (RC3225F9760CS - Samsung Electro-Mechanics): The RC3225F9760CS is recommended for new designs and applications where Active product status and continuous manufacturer support are required. This part carries ROHS3 compliance and REACH unaffected status, meeting standard industrial and commercial regulatory requirements.

Substitute Part (ERJ-14NF9760U - Panasonic Electronic Components): The ERJ-14NF9760U is suitable for applications where supply of the primary part is unavailable or where the enhanced power rating (0.5W versus 0.333W) provides design margin benefits. The AEC-Q200 automotive qualification indicates this component meets automotive-grade reliability standards. However, the "Not For New Designs" product status indicates this part is in mature or declining production phase. Selection of this substitute should be limited to replacement or legacy system applications where the primary part cannot be sourced.

Compliance Considerations: Both parts maintain ROHS3 compliance and REACH unaffected status. Dimensional variations between the two parts remain within standard package tolerances for the 1210 (3225 Metric) format. The higher power rating of the substitute part does not create incompatibility in circuits designed for the original 0.333W specification.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-14NF9760U be used as a direct replacement for the RC3225F9760CS in existing designs?

A: Yes. The ERJ-14NF9760U meets all mandatory electrical and mechanical parameters of the RC3225F9760CS. The higher power rating (0.5W versus 0.333W) is compatible with circuits designed for the original part. Physical dimensions remain within package specification tolerances.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF9760U?

A: This status indicates the Panasonic part is in mature production phase with no active development or enhancement roadmap. While the part remains functionally qualified and available, Panasonic does not recommend its use in new product designs. For new designs, the RC3225F9760CS (Active status) is the preferred selection.

Q: Are there packaging format differences between these parts?

A: The RC3225F9760CS uses standard packaging, while the ERJ-14NF9760U is supplied in Tape & Reel (TR) format. This difference affects handling, storage, and automated assembly processes but does not impact electrical or mechanical performance of the component itself.

Q: Do the dimensional differences between the two parts affect PCB layout?

A: The dimensional variations (width: 0.100" versus 0.098"; height: 0.026" versus 0.028") are within standard 1210 package tolerances and do not require PCB layout modifications. Both parts are mechanically compatible with standard 1210 footprints.

Q: What certifications does the ERJ-14NF9760U carry that the RC3225F9760CS does not?

A: The ERJ-14NF9760U carries AEC-Q200 automotive qualification, indicating compliance with automotive-grade reliability and testing standards. The RC3225F9760CS does not list this certification. If automotive qualification is required, the ERJ-14NF9760U provides this additional assurance.

Q: Are both parts RoHS compliant?

A: Yes. Both the RC3225F9760CS and ERJ-14NF9760U are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for industrial and commercial applications.
