RC5025F2611CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F2611CS is a 2.61 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 2010 (5025 Metric) package format with a power rating of 0.667W (2/3W). This component is classified as Active product status and features moisture-resistant construction suitable for general industrial applications. The part is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts become necessary when the primary part experiences supply constraints, inventory depletion, or when design requirements permit higher power ratings or automotive-grade certifications. The substitute parts listed maintain electrical equivalence while offering alternative manufacturing sources and enhanced specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F2611CS is determined by strict adherence to the following parameters:

Mandatory Matching Parameters:

• Resistance Value: 2.61 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 2010 (5025 Metric) (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 required)

Allowable Variation Parameters:

• Power Rating: Substitute parts may have equal or higher power ratings (0.667W minimum)
• Height - Seated (Max): Substitute parts may have equal or slightly higher seated height within mechanical tolerance
• Features: Substitute parts may include additional features (such as Automotive AEC-Q200 certification) without compromising base functionality

The two substitute parts listed (CRCW20102K61FKEF and ERJ-12SF2611U) meet all mandatory matching parameters and offer enhanced power ratings of 0.75W (3/4W) with automotive-grade AEC-Q200 certification.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (RC5025F2611CS): Select the RC5025F2611CS when the application requires a standard industrial-grade thick film resistor with moisture-resistant properties and does not require automotive certification. This part maintains Active product status with established supply availability.

First Substitute (CRCW20102K61FKEF): The CRCW20102K61FKEF from Vishay Dale is the preferred substitute option. It maintains Active product status, provides identical electrical and mechanical specifications, and offers enhanced power rating (0.75W vs. 0.667W) with Automotive AEC-Q200 certification. The increased seated height (0.028" vs. 0.026") remains within acceptable mechanical tolerances for standard PCB assembly processes. This part is suitable for both industrial and automotive applications.

Secondary Substitute (ERJ-12SF2611U): The ERJ-12SF2611U from Panasonic Electronic Components provides electrical and mechanical equivalence with identical power rating enhancement and AEC-Q200 certification. However, this part carries "Not For New Designs" product status, indicating it is in end-of-life phase. Selection of this part is appropriate only for legacy system maintenance or when supply of active alternatives is unavailable.

Compliance Considerations: All three parts maintain ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity rating, and REACH Unaffected status. Selection between parts does not introduce compliance risk.

Frequently Asked Questions (FAQ)

Q: Can CRCW20102K61FKEF be used as a direct replacement for RC5025F2611CS?

A: Yes. The CRCW20102K61FKEF meets all mandatory electrical parameters (2.61 kOhms ±1%, ±100ppm/°C, -55°C ~ 155°C operating range) and mechanical specifications (2010 package, 5.00mm x 2.50mm dimensions). The increased power rating (0.75W vs. 0.667W) and seated height (0.028" vs. 0.026") are allowable variations that do not compromise functionality or PCB assembly compatibility.

Q: What is the difference between the two substitute parts?

A: Both CRCW20102K61FKEF and ERJ-12SF2611U provide identical electrical specifications and power ratings. The primary difference is product status: CRCW20102K61FKEF is Active, while ERJ-12SF2611U is Not For New Designs. For new designs, CRCW20102K61FKEF is the appropriate selection.

Q: Does the increased seated height of substitute parts affect PCB assembly?

A: The seated height increase from 0.026" (0.66mm) to 0.028" (0.70mm) is a 0.002" (0.04mm) variation. This difference is within standard PCB assembly tolerances and does not require design modification or reflow profile adjustment.

Q: Are the substitute parts suitable for automotive applications?

A: CRCW20102K61FKEF and ERJ-12SF2611U both carry Automotive AEC-Q200 certification, making them suitable for automotive-grade applications. The RC5025F2611CS does not carry this certification and is classified as industrial-grade.

Q: Can ERJ-12SF2611U be used in new designs?

A: ERJ-12SF2611U carries "Not For New Designs" product status. While electrically and mechanically equivalent, this part is in end-of-life phase. For new designs, use RC5025F2611CS or CRCW20102K61FKEF.

Q: Do all three parts have the same moisture sensitivity rating?

A: Yes. All three parts carry MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: What is the impact of the higher power rating in substitute parts?

A: The substitute parts' higher power rating (0.75W vs. 0.667W) provides additional thermal margin in the application. This is a beneficial characteristic that does not introduce compatibility issues. The part will operate at lower junction temperature under identical load conditions.
