RC5025F5110CS Equivalent & Substitute Parts

Part Overview

The RC5025F5110CS is a 511 Ohm ±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 moisture resistant and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with 952 pieces currently in stock.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and performance envelope. Alternative sources provide equivalent or superior power ratings while preserving the core functional parameters required for direct circuit board replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F5110CS is determined by the following mandatory parameters:

Electrical Equivalence Requirements:

• Resistance value: 511 Ohms
• Tolerance: ±1%
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Compatibility Requirements:

• Package / Case: 2010 (5025 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Requirements:

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts identified in this reference maintain all electrical parameters and mechanical compatibility. Power rating variations are permitted when the substitute part equals or exceeds the original specification, as higher power ratings provide equivalent or improved performance margins within the same physical footprint.

Parameter Comparison

Engineering Selection Recommendations

RC5025F5110CS (Samsung Electro-Mechanics) - Primary Part

Active product status with established supply chain. Moisture resistant construction with MSL 1 rating. ROHS3 compliant. Suitable for new designs and production applications requiring Samsung component qualification.

CRCW2010511RFKEF (Vishay Dale) - Preferred Substitute

Active product status with high inventory availability (32,300 pieces). Automotive AEC-Q200 rated, providing enhanced reliability qualification. Power rating of 0.75W exceeds original specification. ROHS3 compliant with MSL 1 rating. Recommended for applications requiring automotive-grade component certification or when higher power margin is beneficial.

ERJ-12SF5110U (Panasonic Electronic Components) - Secondary Substitute

Not For New Designs product status. Automotive AEC-Q200 rated with 0.75W power rating. ROHS3 compliant with MSL 1 rating. Suitable for legacy design support and replacement applications where existing Panasonic qualification is established. Not recommended for new product development.

Frequently Asked Questions (FAQ)

Q: Can CRCW2010511RFKEF directly replace RC5025F5110CS in existing designs?

A: Yes. Both components share identical resistance (511 Ohms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), package footprint (2010/5025 Metric), and compliance ratings (ROHS3, MSL 1). The CRCW2010511RFKEF provides a higher power rating (0.75W vs. 0.667W), which is compatible with the original circuit design.

Q: What is the difference between the RC5025F5110CS and ERJ-12SF5110U?

A: Electrical and mechanical specifications are identical. The primary difference is product status: RC5025F5110CS is Active, while ERJ-12SF5110U is Not For New Designs. Both maintain the same 2010 package, 511 Ohm resistance, ±1% tolerance, and operating temperature range. ERJ-12SF5110U is suitable for replacement and legacy support only.

Q: Are there height differences between these parts?

A: Yes. RC5025F5110CS has a maximum seated height of 0.026" (0.66mm), while CRCW2010511RFKEF and ERJ-12SF5110U both have a maximum seated height of 0.028" (0.70mm). This 0.002" (0.04mm) difference is within typical PCB assembly tolerances and does not affect functional compatibility in standard applications.

Q: Why does CRCW2010511RFKEF have a higher power rating?

A: The 0.75W rating of CRCW2010511RFKEF compared to the 0.667W rating of RC5025F5110CS reflects the manufacturer's design specifications for the same physical package. Both components occupy identical footprints and operate within the same temperature range. The higher power rating provides additional thermal margin without affecting electrical performance or package compatibility.

Q: Are all three parts RoHS3 compliant?

A: Yes. RC5025F5110CS, CRCW2010511RFKEF, and ERJ-12SF5110U are all ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited). All parts are suitable for applications requiring RoHS compliance.

Q: What does AEC-Q200 certification mean for CRCW2010511RFKEF and ERJ-12SF5110U?

A: AEC-Q200 is an automotive industry qualification standard for passive components. Both CRCW2010511RFKEF and ERJ-12SF5110U carry this certification, indicating they meet enhanced reliability and performance requirements for automotive applications. This certification is not present on the RC5025F5110CS.
