RC5025F3833CS Equivalent & Substitute Parts

Part Overview

The RC5025F3833CS is a 383 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated for 0.667W (2/3W) power dissipation in a 2010 (5025 Metric) surface mount package. This component is classified as Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the same resistance value, tolerance, package footprint, and operating temperature range. The primary substitute identified is the ERJ-12SF3833U from Panasonic Electronic Components, which maintains critical electrical parameters while offering higher power rating and automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F3833CS is determined by strict equivalence across the following parameters:

Critical Electrical Parameters:

• Resistance value: 383 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match or wider range acceptable)

Critical Mechanical Parameters:

• Package / Case: 2010 (5025 Metric) (exact match required)
• Footprint dimensions: 0.197" L x 0.098" W / 5.00mm x 2.50mm (exact match required)
• Number of Terminations: 2 (exact match required)

Environmental & Compliance Parameters:

• Moisture Sensitivity Level: MSL 1 or better (equivalent or lower MSL acceptable)
• RoHS Status: Compliance level must be maintained or improved

The ERJ-12SF3833U qualifies as a substitute because it maintains all critical electrical parameters (383 kOhms ±1%, thick film, ±100ppm/°C, -55°C ~ 155°C), identical mechanical footprint (2010 package, 5.00mm x 2.50mm), and equivalent environmental rating (MSL 1). The higher power rating (0.75W vs 0.667W) and automotive AEC-Q200 qualification represent performance enhancements rather than deviations.

Engineering Selection Recommendations

Primary Selection: RC5025F3833CS (Samsung Electro-Mechanics)

The RC5025F3833CS is the recommended primary choice for new designs. This component carries Active product status, ensuring continued manufacturer support and availability. ROHS3 compliance satisfies current regulatory requirements for most commercial and industrial applications. The 0.667W power rating is sufficient for standard signal conditioning and biasing circuits in the 383 kOhms resistance class.

Substitute Selection: ERJ-12SF3833U (Panasonic Electronic Components)

The ERJ-12SF3833U is electrically and mechanically equivalent to the RC5025F3833CS and qualifies as a direct substitute when:

• Higher power dissipation capability (0.75W vs 0.667W) is beneficial or required
• Automotive-grade reliability (AEC-Q200) is specified for the application
• Supply chain constraints limit availability of the primary part

Important Compliance Consideration:

The ERJ-12SF3833U carries "Not For New Designs" status and is RoHS non-compliant. This substitute is suitable only for:

• Replacement or repair of existing assemblies using this component
• Applications where RoHS compliance is not mandated
• Legacy product support where the original design specification included this part

For new product development, the RC5025F3833CS remains the appropriate selection due to Active status and ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF3833U be used as a direct replacement for RC5025F3833CS in new designs?

A: No. While the ERJ-12SF3833U is electrically and mechanically equivalent, it carries "Not For New Designs" status and is RoHS non-compliant. New designs must use RC5025F3833CS to ensure regulatory compliance and long-term manufacturer support.

Q: What is the significance of the 0.08W power rating difference (0.75W vs 0.667W)?

A: The ERJ-12SF3833U's higher power rating (0.75W) is a performance enhancement that does not affect substitution compatibility. A component rated for higher power dissipation can safely operate in applications designed for lower power ratings. This difference does not create any functional or reliability concerns.

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

A: The footprint dimensions are identical (5.00mm x 2.50mm, 2010 package). The maximum seated height differs slightly (0.66mm vs 0.70mm), a 0.04mm difference that is negligible for standard PCB assembly and does not affect component placement or clearance in typical circuit designs.

Q: Why is the ERJ-12SF3833U marked "Not For New Designs"?

A: This designation indicates that Panasonic has discontinued active development and marketing of this part for new applications. While existing inventory may be available, the manufacturer does not guarantee long-term supply or support. New designs should specify the RC5025F3833CS to ensure supply chain continuity.

Q: What does RoHS3 compliance mean for the RC5025F3833CS?

A: ROHS3 compliance certifies that the RC5025F3833CS meets the Restriction of Hazardous Substances Directive requirements, limiting the use of lead, cadmium, mercury, and other restricted materials. This compliance is required for products sold in the European Union and is increasingly mandated by global customers and regulatory bodies.

Q: Can these parts be used interchangeably in automotive applications?

A: The ERJ-12SF3833U carries AEC-Q200 automotive qualification, making it suitable for automotive-grade applications. The RC5025F3833CS does not specify automotive qualification. If AEC-Q200 certification is required, the ERJ-12SF3833U is the appropriate choice, provided RoHS compliance is not mandated for the application.

Q: What does MSL 1 (Unlimited) moisture sensitivity rating mean?

A: MSL 1 indicates the lowest moisture sensitivity level. Components with this rating can be stored indefinitely without special moisture control measures and do not require baking before soldering. Both parts share this favorable rating, eliminating moisture handling as a substitution concern.
