RC3225F3092CS Equivalent & Substitute Parts

Part Overview

The RC3225F3092CS is a 30.9 kOhms ±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 is currently in stock with 982 pieces available.

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

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F3092CS is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 30.9 kOhms
• Tolerance: ±1%
• Package / Case: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Power Rating: Substitute parts may have equal or higher power ratings than the original 0.333W specification
• Physical Dimensions: Minor variations within the 1210 package standard are acceptable
• Packaging Format: Original packaging is bulk; substitutes may be supplied in Tape & Reel format

The ERJ-14NF3092U from Panasonic Electronic Components qualifies as a substitute because it maintains all mandatory parameters while providing a higher power rating of 0.5W (1/2W), which is compatible with applications designed for the original part.

Engineering Selection Recommendations

RC3225F3092CS (Samsung Electro-Mechanics) - Primary Selection:

• Active product status ensures continued availability and manufacturer support
• Recommended for new designs and long-term production applications
• Current inventory of 982 pieces supports immediate procurement

ERJ-14NF3092U (Panasonic Electronic Components) - Secondary Selection:

• Classified as "Not For New Designs," indicating end-of-life or transition status
• Suitable for legacy system maintenance, repair, and replacement applications only
• Higher power rating (0.5W vs. 0.333W) provides thermal margin in existing designs
• AEC-Q200 automotive qualification available if application requires automotive-grade components
• Inventory of 8810 pieces indicates current availability despite product status designation

For new design implementations, the RC3225F3092CS remains the preferred choice. The ERJ-14NF3092U is appropriate only when the primary part is unavailable and the application permits use of a component designated for non-new designs.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-14NF3092U replace the RC3225F3092CS in existing designs?

A: Yes. The ERJ-14NF3092U maintains identical electrical specifications (30.9 kOhms ±1%, ±100ppm/°C, -55°C ~ 155°C operating range) and package format (1210 / 3225 Metric). The higher power rating (0.5W vs. 0.333W) is compatible with applications designed for the original part.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF3092U?

A: This designation indicates the component is in end-of-life or transition phase. While electrically and mechanically compatible, Panasonic does not recommend this part for new product development. It remains suitable for maintenance, repair, and replacement of existing systems.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within the 1210 package standard. The RC3225F3092CS measures 0.126" L x 0.100" W (3.20mm x 2.55mm) with a maximum seated height of 0.026" (0.66mm). The ERJ-14NF3092U measures 0.126" L x 0.098" W (3.20mm x 2.50mm) with a maximum seated height of 0.028" (0.70mm). These variations remain within acceptable tolerances for 1210 package specifications and do not affect PCB layout compatibility.

Q: Does the higher power rating of the ERJ-14NF3092U affect circuit performance?

A: No. A higher power rating does not alter electrical performance. The 0.5W rating on the ERJ-14NF3092U provides additional thermal capacity compared to the 0.333W specification of the RC3225F3092CS. This is a non-limiting characteristic for substitution.

Q: What packaging formats are available for these parts?

A: The RC3225F3092CS is supplied in bulk packaging. The ERJ-14NF3092U is supplied in Tape & Reel (TR) format. Both formats are compatible with standard PCB assembly processes; format selection depends on production volume and assembly equipment capabilities.

Q: Are both parts RoHS compliant?

A: Yes. Both the RC3225F3092CS and ERJ-14NF3092U are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: Can the ERJ-14NF3092U be used in automotive applications?

A: The ERJ-14NF3092U carries AEC-Q200 automotive qualification. If the application requires automotive-grade components, this part meets that requirement. The RC3225F3092CS does not list automotive qualification in the provided specifications.
