RC5025F3011CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F3011CS is a 3.01 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 moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts become necessary when the original manufacturer part experiences supply constraints, extended lead times, or when design requirements permit higher power ratings or enhanced features such as automotive qualification or anti-sulfur protection. All substitute parts listed maintain electrical equivalence in resistance value, tolerance, and temperature coefficient while offering compatible mechanical packaging.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the RC5025F3011CS is based on strict electrical and mechanical parameter matching. All substitute parts must satisfy the following criteria:

Mandatory Matching Parameters:

• Resistance: 3.01 kOhms (exact match)
• Tolerance: ±1% (exact match)
• Package: 2010 (5025 Metric) (exact match for PCB compatibility)
• Composition: Thick Film (exact match)
• Temperature Coefficient: ±100ppm/°C (exact match)
• Operating Temperature: -55°C ~ 155°C (minimum requirement)
• Terminations: 2 (exact match)
• RoHS Compliance: ROHS3 (minimum requirement)

Acceptable Variations:

• Power Rating: Equal or higher than 0.667W (substitutes rated at 0.75W are acceptable)
• MSL Rating: Equal or better than 1 (Unlimited)
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) are both acceptable for assembly compatibility
• Features: Additional features such as Automotive AEC-Q200 qualification or Anti-Sulfur protection do not disqualify a part from substitution

Product Status Consideration: Parts with Active status are preferred for new designs. Parts with "Not For New Designs" status remain electrically equivalent but should be evaluated based on application lifecycle requirements.

Parameter Comparison

Engineering Selection Recommendations

For Active Product Status Applications:

AC2010FK-073K01L (YAGEO) is recommended as the primary substitute. This part maintains Active product status, carries Automotive AEC-Q200 qualification, and provides 0.75W power rating with moisture-resistant construction. Packaging in Tape & Reel format supports automated assembly processes.

RMCF2010FT3K01 (Stackpole Electronics Inc) serves as an alternative with Active status and Automotive AEC-Q200 qualification. Cut Tape packaging is suitable for lower-volume or manual assembly operations.

RMCS2010FT3K01 (Stackpole Electronics Inc) offers Active status with Anti-Sulfur protection and Tape & Reel packaging. This part is suitable for applications requiring enhanced corrosion resistance in high-sulfur environments.

CRCW20103K01FKEF (Vishay Dale) provides Active status with Automotive AEC-Q200 qualification and Tape & Reel packaging, offering broad industry availability.

For Applications Not Requiring New Design Status:

ERJ-12SF3011U (Panasonic Electronic Components) is electrically and mechanically equivalent with Automotive AEC-Q200 qualification. Product status is "Not For New Designs," making this part suitable for legacy system maintenance, repair, or replacement applications where design freeze has occurred.

Compliance Verification:

All listed substitutes maintain ROHS3 compliance and MSL 1 (Unlimited) rating, ensuring regulatory and environmental compatibility with the original RC5025F3011CS specification.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RC5025F3011CS with a part rated at 0.75W instead of 0.667W?

A: Yes. All listed substitute parts are rated at 0.75W (3/4W), which exceeds the original 0.667W (2/3W) specification. Higher power ratings provide additional thermal margin and are electrically compatible. The circuit will operate within design parameters.

Q: Are the dimensional differences between substitute parts significant?

A: Seated height variations range from 0.026" (0.65mm) to 0.028" (0.70mm). These differences are within standard PCB assembly tolerances and do not affect footprint compatibility. All parts use the identical 2010 (5025 Metric) package with 5.00mm length and 2.50mm width.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is supplied on continuous carrier tape suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging is supplied in shorter tape segments suitable for manual assembly or lower-volume production. Both formats contain identical components; packaging format selection depends on assembly process requirements.

Q: Why do some substitutes include Automotive AEC-Q200 qualification when the original part does not?

A: Automotive AEC-Q200 qualification indicates the part meets automotive industry reliability and quality standards. This additional qualification does not disqualify the part from use in non-automotive applications. Parts with AEC-Q200 qualification are suitable for any application requiring the specified electrical and mechanical parameters.

Q: Can I use ERJ-12SF3011U if it has "Not For New Designs" status?

A: ERJ-12SF3011U is electrically and mechanically equivalent to RC5025F3011CS and remains suitable for replacement, repair, or maintenance of existing systems. "Not For New Designs" status indicates the manufacturer recommends using alternative parts for new product development. For legacy system support or field replacements, this part is acceptable.

Q: What does Anti-Sulfur protection mean in RMCS2010FT3K01?

A: Anti-Sulfur protection refers to construction features that resist corrosion from hydrogen sulfide and other sulfur-containing compounds in high-pollution or industrial environments. This feature does not affect electrical performance in standard applications but provides enhanced reliability in corrosive atmospheres.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, ensuring compatibility with environmental and regulatory requirements equivalent to the original RC5025F3011CS.

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

A: MSL 1 (Unlimited) indicates the component has minimal moisture sensitivity and requires no special moisture control during storage, handling, or assembly. This rating applies to all listed parts and the original component.
