RC5025F1333CS Equivalent & Substitute Parts

Part Overview

The RC5025F1333CS is a 133 kOhms ±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 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 ERJ-12SF1333U from Panasonic Electronic Components serves as a functional equivalent, though with differing power rating and product lifecycle status.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the RC5025F1333CS is based on the following criteria:

Mandatory Matching Parameters:

• Resistance value: 133 kOhms (exact match required)
• Tolerance: ±1% (equal or tighter tolerance acceptable)
• Package footprint: 2010 (5025 Metric) (physical compatibility required)
• Temperature coefficient: ±100ppm/°C (equal or better stability required)
• Operating temperature range: -55°C ~ 155°C (substitute must support full range)
• Composition: Thick Film (technology type)
• RoHS3 compliance (regulatory requirement)

Acceptable Variation Parameters:

• Power rating: Substitute must equal or exceed 0.667W minimum
• Moisture sensitivity level: Substitute must be MSL 1 or lower (less restrictive)
• Product status: Active or Not For New Designs both acceptable for equivalent function
• Packaging format: Tape & Reel acceptable for equivalent component

The ERJ-12SF1333U meets all mandatory parameters with a higher power rating (0.75W vs. 0.667W), making it functionally compatible for applications within the RC5025F1333CS specifications.

Parameter Comparison

Engineering Selection Recommendations

RC5025F1333CS (Primary Selection): Select the RC5025F1333CS for new designs and applications requiring long-term component availability. This part maintains Active product status with Samsung Electro-Mechanics, ensuring continued supply and manufacturing support. The component is fully RoHS3 compliant with MSL 1 rating, suitable for standard PCB assembly processes without moisture-sensitive handling requirements.

ERJ-12SF1333U (Substitute Selection): The ERJ-12SF1333U from Panasonic Electronic Components is electrically and mechanically compatible as a direct substitute. This part carries AEC-Q200 automotive qualification, providing enhanced reliability documentation for applications requiring automotive-grade components. However, the "Not For New Designs" status indicates this part is in end-of-life phase. Use ERJ-12SF1333U only for:

• Replacement in existing production lines
• Maintenance and repair of fielded equipment
• Applications where automotive AEC-Q200 qualification is required

The 0.75W power rating of the ERJ-12SF1333U exceeds the 0.667W requirement of the RC5025F1333CS, providing additional thermal margin in power dissipation scenarios. Maximum seated height difference (0.028" vs. 0.026") is negligible for standard PCB assembly.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF1333U replace RC5025F1333CS in new product designs?

A: No. The ERJ-12SF1333U carries "Not For New Designs" status, indicating end-of-life phase. Use RC5025F1333CS for new designs to ensure long-term supply availability and manufacturing support.

Q: Are the physical dimensions compatible between these parts?

A: Yes. Both parts use the 2010 (5025 Metric) package with identical length and width (0.197" x 0.098" / 5.00mm x 2.50mm). Maximum seated height differs by 0.002" (0.04mm), which is within standard PCB assembly tolerances and does not affect compatibility.

Q: Does the higher power rating of ERJ-12SF1333U (0.75W vs. 0.667W) affect circuit performance?

A: No. A higher power rating indicates greater thermal capability and does not change electrical performance. The substitute can safely handle the same or lower power dissipation as the original part.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RC5025F1333CS and ERJ-12SF1333U are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating, requiring no special handling during assembly.

Q: What is the significance of AEC-Q200 qualification on the ERJ-12SF1333U?

A: AEC-Q200 is an automotive industry standard qualification indicating enhanced reliability testing and documentation. This qualification is relevant only if your application requires automotive-grade component certification. Standard industrial applications do not require this qualification.

Q: Can I use ERJ-12SF1333U in existing RC5025F1333CS applications?

A: Yes, for replacement and repair scenarios. The electrical and mechanical parameters are compatible. However, verify component availability with your supplier, as ERJ-12SF1333U is in end-of-life status.

Q: What is the temperature coefficient significance?

A: Both parts have ±100ppm/°C temperature coefficient, meaning resistance value changes by approximately 0.01% per degree Celsius. This specification is identical between parts and ensures equivalent circuit stability across the -55°C to 155°C operating range.
