RC5025F2610CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F2610CS is a 261 Ohm ±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. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained within the same package footprint and performance envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F2610CS is determined by the following criteria:

Mandatory Matching Parameters:

• Resistance value: 261 Ohms
• Tolerance: ±1%
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Terminations: 2
• RoHS3 Compliance

Allowable Variation:

• Power Rating: Substitute parts rated at 0.75W (3/4W) or higher are acceptable, as they provide equal or greater power dissipation capability within the same package footprint.

Both identified substitute parts meet these criteria with increased power ratings (0.75W vs. 0.667W), maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

CRCW2010261RFKEF (Vishay Dale) is the primary substitute option. This part maintains Active product status, carries AEC-Q200 automotive qualification, and provides 0.75W power rating within the identical 2010 package footprint. All electrical parameters, compliance certifications (ROHS3, REACH Unaffected), and environmental ratings align with the RC5025F2610CS.

ERJ-12SF2610U (Panasonic Electronic Components) is a secondary substitute option. While electrically and mechanically equivalent with matching 261 Ohm resistance, ±1% tolerance, and 2010 package dimensions, this part carries "Not For New Designs" product status. This designation indicates the manufacturer is discontinuing or has discontinued active promotion of this component for new applications. Selection of this part is appropriate only for legacy system maintenance or replacement scenarios where design continuity is required.

For new designs and standard procurement, CRCW2010261RFKEF is the recommended substitute when RC5025F2610CS availability is constrained.

Frequently Asked Questions (FAQ)

Q: Can CRCW2010261RFKEF replace RC5025F2610CS in existing designs?

A: Yes. Both parts share identical electrical specifications (261 Ohms ±1%, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range) and mechanical compatibility (2010 package, 5.00mm x 2.50mm footprint, 2 terminations). The CRCW2010261RFKEF provides higher power rating (0.75W vs. 0.667W), which does not create compatibility issues in applications designed for the original part.

Q: What is the significance of the "Not For New Designs" status on ERJ-12SF2610U?

A: This designation indicates Panasonic has classified this part as obsolete or end-of-life for new product development. While the part remains electrically and mechanically compatible, manufacturers typically apply this status when discontinuing active production or support. New designs should prioritize Active-status alternatives such as CRCW2010261RFKEF.

Q: Are there height differences between these parts?

A: The RC5025F2610CS has a maximum seated height of 0.026" (0.66mm), while both substitute parts (CRCW2010261RFKEF and ERJ-12SF2610U) have a maximum seated height of 0.028" (0.70mm). This 0.002" (0.04mm) difference is negligible for standard PCB assembly and does not affect electrical performance or mechanical fit in typical applications.

Q: Do all three parts meet RoHS3 compliance?

A: Yes. RC5025F2610CS, CRCW2010261RFKEF, and ERJ-12SF2610U are all ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What packaging formats are available for the substitute parts?

A: CRCW2010261RFKEF and ERJ-12SF2610U are supplied in Tape & Reel (TR) format, which is standard for automated PCB assembly operations. The original RC5025F2610CS packaging format is not specified in the provided data.
