RC5025F2612CS Equivalent & Substitute Parts

Part Overview

The RC5025F2612CS is a 26.1 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 currently in stock with 779 pieces available.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the same resistance value, tolerance, package dimensions, and operating temperature range. The ERJ-12SF2612U from Panasonic Electronic Components represents a qualified alternative, though with differing power rating and product lifecycle status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F2612CS is determined by strict alignment with the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Resistance value: 26.1 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package: 2010 (5025 Metric) (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match or superior range required)
• Composition: Thick Film (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match or superior required)

Secondary Consideration:

• Power rating: Substitute parts with equal or higher power dissipation capacity are acceptable, as they provide equivalent or enhanced thermal performance within the same package envelope.

The ERJ-12SF2612U meets all primary criteria with a higher power rating (0.75W vs. 0.667W), making it electrically and mechanically compatible. However, its "Not For New Designs" product status requires evaluation against project lifecycle requirements.

Parameter Comparison

Engineering Selection Recommendations

For Active Product Designs: The RC5025F2612CS (Samsung Electro-Mechanics) is the primary selection for new designs. It maintains Active product status with confirmed inventory availability (779 pieces), ensuring long-term supply chain stability and manufacturer support.

For Existing Designs or Supply Continuity: The ERJ-12SF2612U (Panasonic Electronic Components) is electrically and mechanically compatible as a direct substitute. All critical electrical parameters align exactly: 26.1 kOhms resistance, ±1% tolerance, ±100ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. The package dimensions are identical, and the higher power rating (0.75W vs. 0.667W) provides thermal margin within the same 2010 form factor.

Product Lifecycle Consideration: The ERJ-12SF2612U carries "Not For New Designs" status, indicating Panasonic has transitioned this part to mature/legacy classification. This designation does not affect electrical performance or reliability for existing applications but signals potential future availability constraints. Use this substitute only when supply of the primary part is unavailable or when supporting legacy equipment.

Compliance Verification: Both parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes. Both maintain MSL 1 (Unlimited) moisture sensitivity rating, requiring no special handling beyond standard ESD precautions.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF2612U replace RC5025F2612CS in all applications?

A: Yes, from an electrical and mechanical standpoint. The ERJ-12SF2612U meets all critical specifications: identical resistance (26.1 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and package dimensions (2010/5025 Metric). The higher power rating (0.75W vs. 0.667W) is compatible. However, verify your project's new design requirements, as the ERJ-12SF2612U is classified "Not For New Designs."

Q: What is the difference in power rating between these parts?

A: The RC5025F2612CS is rated for 0.667W (2/3W), while the ERJ-12SF2612U is rated for 0.75W (3/4W). Both are housed in the identical 2010 (5025 Metric) package. The higher power rating of the Panasonic part indicates greater thermal dissipation capability within the same physical envelope. If your circuit requires the full 0.667W dissipation, both parts are suitable. The Panasonic part provides additional thermal margin.

Q: Are there physical mounting differences?

A: No significant differences exist. Both parts use the 2010 (5025 Metric) package with identical length (0.197" / 5.00mm) and width (0.098" / 2.50mm). The maximum seated height differs slightly: RC5025F2612CS at 0.026" (0.66mm) and ERJ-12SF2612U at 0.028" (0.70mm). This 0.002" (0.04mm) variance is negligible for standard PCB assembly and does not affect board layout or component clearance in typical applications.

Q: Do both parts require the same handling and storage conditions?

A: Yes. Both parts carry MSL 1 (Unlimited) moisture sensitivity rating, meaning they require no special moisture control during storage or handling beyond standard ESD precautions. Both are ROHS3 Compliant and REACH Unaffected, with identical environmental compliance profiles.

Q: Why is the Panasonic part marked "Not For New Designs"?

A: This designation indicates that Panasonic has classified the ERJ-12SF2612U as a mature or legacy product. The manufacturer is not actively promoting it for new design adoption, though the part remains available and fully functional. This status typically reflects product portfolio optimization rather than performance or reliability concerns. Use this part for replacement, repair, or legacy system support only.

Q: What is the temperature coefficient significance?

A: Both parts specify ±100ppm/°C temperature coefficient, meaning the resistance value will drift by approximately 0.01% per degree Celsius change from the reference temperature. This specification is identical between the two parts, ensuring equivalent stability across the -55°C ~ 155°C operating range. This parameter is critical for precision analog circuits and should match exactly when substituting.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control. Both carry identical HTSUS code (8533.21.0030). Compliance profiles are equivalent, and either part satisfies the same regulatory requirements.
