RC5025F3483CS Equivalent & Substitute Parts

Part Overview

The RC5025F3483CS is a 348 kOhm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.667W (2/3W) in a 2010 (5025 Metric) package. This component is classified as Active product status and is ROHS3 compliant with moisture resistant properties suitable for general industrial applications.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit alternative manufacturers meeting equivalent electrical and mechanical specifications. The RC5025F3483CS has documented substitute availability through Panasonic Electronic Components.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F3483CS is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Resistance value: 348 kOhms
• Tolerance: ±1%
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Number of Terminations: 2
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: Substitute parts may have equal or higher power ratings (0.667W minimum)
• Physical dimensions: Seated height may vary within component tolerance
• Packaging format: Original packaging (bulk) may differ from substitute packaging (Tape & Reel)
• Compliance certifications: Substitutes may have additional certifications (e.g., AEC-Q200) or different RoHS status

The ERJ-12SF3483U from Panasonic Electronic Components meets all critical matching parameters with a higher power rating of 0.75W (3/4W), making it a valid electrical and mechanical substitute.

Parameter Comparison

Engineering Selection Recommendations

RC5025F3483CS (Samsung Electro-Mechanics):

• Primary selection for new designs
• Active product status ensures long-term availability and manufacturer support
• ROHS3 compliant for applications requiring environmental compliance
• Moisture resistant properties with MSL 1 rating suitable for standard storage and handling

ERJ-12SF3483U (Panasonic Electronic Components):

• Valid substitute when RC5025F3483CS is unavailable
• Higher power rating (0.75W vs 0.667W) provides additional thermal margin in circuit operation
• Automotive AEC-Q200 qualification indicates enhanced reliability for demanding applications
• Not For New Designs status indicates this part is in mature/legacy phase; use only for replacement or when supply of primary part is exhausted
• RoHS non-compliant status requires verification against project compliance requirements before selection

Compliance Considerations:

• If ROHS3 compliance is mandatory, RC5025F3483CS is the required selection
• If RoHS compliance is not required and AEC-Q200 automotive qualification is beneficial, ERJ-12SF3483U is acceptable
• Both parts are REACH Unaffected and classified as EAR99 for export control purposes

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF3483U be used as a direct replacement for RC5025F3483CS in existing designs?

A: Yes, from an electrical and mechanical standpoint. The ERJ-12SF3483U matches all critical parameters: 348 kOhm resistance, ±1% tolerance, 2010 package, thick film composition, and identical temperature characteristics. The higher power rating (0.75W vs 0.667W) is not a limitation. However, verify RoHS compliance requirements for your application, as ERJ-12SF3483U is RoHS non-compliant while RC5025F3483CS is ROHS3 compliant.

Q: What does "Not For New Designs" mean for the ERJ-12SF3483U?

A: This product status indicates that Panasonic is not recommending this part for new circuit designs. It remains available for replacement and legacy applications but may have limited future availability. For new designs, RC5025F3483CS is the preferred selection.

Q: Are there dimensional compatibility issues between these parts?

A: No. Both parts use the 2010 (5025 Metric) package with identical length (0.197" / 5.00mm) and width (0.098" / 2.50mm). The seated height differs slightly (0.026" vs 0.028"), which is within standard component tolerance and does not affect PCB layout or assembly.

Q: What is the significance of the higher power rating on the ERJ-12SF3483U?

A: The ERJ-12SF3483U is rated at 0.75W compared to the RC5025F3483CS at 0.667W. This higher rating provides additional thermal capacity and allows the substitute part to dissipate more power without exceeding temperature limits. In circuits where the original part operates near its power limit, the substitute offers improved thermal margin.

Q: Can I use these parts interchangeably in automated assembly?

A: Yes, both parts are available in standard SMD packaging formats. RC5025F3483CS is supplied in bulk packaging, while ERJ-12SF3483U is available in Tape & Reel (TR) format. Verify your assembly equipment compatibility with the packaging format before procurement.

Q: What is Moisture Sensitivity Level 1 (Unlimited)?

A: MSL 1 indicates the component has unlimited shelf life under normal storage conditions (typically 30°C / 60% RH). No special moisture control or baking procedures are required before assembly. Both parts carry this rating.

Q: Are there any export control restrictions on these parts?

A: Both parts are classified as EAR99 under U.S. export control regulations, indicating they are not subject to specific licensing requirements for most destinations. Verify current export regulations for your specific end-use and destination country.
