RC5025F3831CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F3831CS is a 3.83 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 with full RoHS3 compliance and 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 ERJ-12SF3831U from Panasonic Electronic Components carries a higher power rating (0.75W) and automotive qualification, though it is designated as Not For New Designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F3831CS is determined by strict adherence to the following electrical and mechanical parameters:

Mandatory Matching Criteria:

• Resistance value: 3.83 kOhms (exact match required)
• Tolerance: ±1% (substitute tolerance must not exceed this value)
• Package designation: 2010 (5025 Metric) surface mount footprint
• Composition: Thick film construction
• RoHS3 compliance status

Allowable Variance Criteria:

• Power rating: Substitute must equal or exceed 0.667W minimum
• Temperature coefficient: Substitute must equal or better than ±100ppm/°C
• Operating temperature range: Substitute must support -55°C to 155°C minimum
• Moisture sensitivity: Substitute must equal or better than MSL 1

The ERJ-12SF3831U from Panasonic meets all mandatory matching criteria and exceeds the power rating requirement (0.75W vs. 0.667W). Both components share identical resistance, tolerance, package footprint, composition, temperature coefficient, and operating temperature specifications. The primary distinction is the product lifecycle status: RC5025F3831CS is Active, while ERJ-12SF3831U is designated Not For New Designs.

Engineering Selection Recommendations

For Active Product Designs: The RC5025F3831CS (Samsung Electro-Mechanics) is the primary selection for new designs. This component maintains Active product status, ensuring long-term availability and manufacturer support. It meets all RoHS3 compliance requirements and carries unlimited moisture sensitivity rating suitable for standard industrial and commercial applications.

For Existing Designs or Legacy Support: The ERJ-12SF3831U (Panasonic Electronic Components) is electrically and mechanically compatible with the RC5025F3831CS. The substitute provides equivalent electrical performance with a higher power rating margin (0.75W vs. 0.667W). However, this component is designated Not For New Designs, indicating Panasonic has discontinued active development and support. Use of ERJ-12SF3831U is appropriate only for sustaining production of existing designs or where inventory availability of the primary part is constrained.

Compliance Considerations: Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution. Both carry EAR99 export classification and identical HTSUS commodity codes (8533.21.0030).

Automotive Applications: The ERJ-12SF3831U carries AEC-Q200 automotive qualification, while the RC5025F3831CS does not specify automotive rating. For automotive applications requiring AEC-Q200 certification, the Panasonic component is the appropriate selection despite its Not For New Designs status.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF3831U directly replace RC5025F3831CS in existing PCB designs?

A: Yes. Both components share identical package footprint (2010/5025 Metric), identical physical dimensions (0.197" L x 0.098" W), and compatible seated heights (0.66mm vs. 0.70mm maximum). No PCB layout modifications are required. Electrical performance is equivalent across all specified parameters.

Q: What is the significance of the higher power rating on the ERJ-12SF3831U?

A: The ERJ-12SF3831U is rated for 0.75W versus the RC5025F3831CS at 0.667W. This 12.5% power rating increase provides additional thermal margin in the same physical package. The substitute can safely operate in applications designed for the primary part without thermal derating concerns.

Q: Why is ERJ-12SF3831U marked "Not For New Designs"?

A: This designation indicates Panasonic has concluded active development and support for this component line. Existing inventory may remain available, but the manufacturer does not recommend this part for new product development. For new designs, RC5025F3831CS (Active status) is the appropriate selection.

Q: Are there differences in moisture sensitivity between these components?

A: No. Both components carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no moisture precautions are required during storage, handling, or assembly. Both are suitable for standard manufacturing environments without special baking or desiccant storage protocols.

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

A: Only the ERJ-12SF3831U carries AEC-Q200 automotive qualification. The RC5025F3831CS does not specify automotive rating. For automotive applications requiring AEC-Q200 certification, ERJ-12SF3831U is the required selection. For non-automotive applications, both components are interchangeable.

Q: What is the temperature coefficient significance for these resistors?

A: Both components specify ±100ppm/°C temperature coefficient. This means resistance value will drift approximately 0.01% per degree Celsius change from the reference temperature. This specification is identical between primary and substitute parts, ensuring equivalent temperature stability performance.

Q: Are packaging formats different between these components?

A: The RC5025F3831CS packaging format is not specified in available data. The ERJ-12SF3831U is supplied in Tape & Reel (TR) format. Verify packaging requirements for your procurement process, as this may affect ordering and handling procedures despite identical component specifications.
