RC5025F1822CS Equivalent & Substitute Parts

Part Overview

The RC5025F1822CS is an 18.2 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 2010 (5025 Metric) package format. This component is rated for 0.667W (2/3W) continuous power dissipation and operates across the temperature range of -55°C to 155°C. The part is classified as Active product status and carries ROHS3 compliance with MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and performance envelope. Alternative sources become necessary for supply chain continuity, inventory availability, or application-specific certifications such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F1822CS is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Resistance value: 18.2 kOhms
• Tolerance: ±1%
• Package format: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

Allowable Variation:

• Power rating: Substitute parts may exceed the 0.667W specification, provided the package dimensions and thermal characteristics remain compatible with the 2010 footprint.

The RMCF2010FT18K2 from Stackpole Electronics Inc meets all critical parameters with an increased power rating of 0.75W (3/4W), maintaining identical resistance, tolerance, temperature coefficient, and operating range specifications. Both parts share the same 2010 package footprint with compatible physical dimensions and termination configuration.

Parameter Comparison

Engineering Selection Recommendations

RC5025F1822CS (Samsung Electro-Mechanics):

• Primary selection for applications requiring the specified 0.667W power rating
• Active product status with established supply chain
• ROHS3 compliant and REACH unaffected
• Moisture resistant thick film construction with MSL 1 rating

RMCF2010FT18K2 (Stackpole Electronics Inc):

• Suitable for applications where increased power dissipation margin is beneficial
• Automotive AEC-Q200 qualification provides enhanced reliability for automotive and harsh environment applications
• Active product status with higher inventory availability (1643 pcs vs 729 pcs)
• ROHS3 compliant and REACH unaffected
• Identical electrical performance with 0.083W additional power capacity

Both parts maintain full compatibility with the 2010 package footprint and PCB layout. The maximum seated height difference of 0.002" (0.04mm) is negligible for standard PCB assembly processes. Selection between these parts depends on application power requirements and environmental qualification needs rather than electrical or mechanical incompatibility.

Frequently Asked Questions (FAQ)

Q: Can RMCF2010FT18K2 be used as a direct replacement for RC5025F1822CS?

A: Yes. Both parts share identical resistance (18.2 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and 2010 package footprint. The RMCF2010FT18K2 provides higher power rating (0.75W vs 0.667W), which is compatible with applications designed for the original part.

Q: What is the difference in physical dimensions between these parts?

A: Both parts measure 0.197" L x 0.098" W (5.00mm x 2.50mm). The maximum seated height differs by 0.002" (0.04mm), with RC5025F1822CS at 0.026" (0.66mm) and RMCF2010FT18K2 at 0.028" (0.70mm). This difference does not affect PCB assembly or component placement.

Q: Are both parts RoHS compliant?

A: Yes. Both RC5025F1822CS and RMCF2010FT18K2 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What does AEC-Q200 qualification mean for the RMCF2010FT18K2?

A: AEC-Q200 is an automotive industry standard qualification that certifies the component for use in automotive applications. This qualification indicates enhanced reliability testing and performance validation for automotive environments. The RC5025F1822CS does not carry this specific automotive certification.

Q: Can I use RC5025F1822CS in an application designed for RMCF2010FT18K2?

A: Yes, provided the application power dissipation does not exceed 0.667W. The RC5025F1822CS meets all electrical specifications and maintains the same package footprint. Applications requiring the full 0.75W capacity of the RMCF2010FT18K2 should not use the lower-rated RC5025F1822CS.

Q: What is the moisture sensitivity rating for both parts?

A: Both parts carry MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture sensitivity restrictions. These components can be stored and handled without special moisture control measures.

Q: Are the termination configurations identical?

A: Yes. Both parts feature 2 terminations in the standard 2010 package configuration, ensuring identical PCB pad layout and soldering requirements.
