RC5025F112CS Equivalent & Substitute Parts

Part Overview

The RC5025F112CS is a 1.1 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) power dissipation and features moisture-resistant construction with an operating temperature range of -55°C to 155°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package format, resistance value, and tolerance class. Alternative sources provide equivalent performance for applications where primary component availability is limited or where specific certifications such as automotive AEC-Q200 qualification are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F112CS is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• Resistance value: 1.1 kOhms
• Tolerance: ±1%
• Package format: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variation:

• Power rating: Substitute parts rated at 0.75W (3/4W) or higher satisfy applications requiring 0.667W (2/3W) performance
• Packaging format: Tape & Reel (TR) substitutes are mechanically compatible with the original component in the same 2010 package footprint

The identified substitute parts CRCW20101K10FKEF (Vishay Dale) and ERJ-12SF1101U (Panasonic Electronic Components) meet all critical matching parameters with increased power rating capability. Both substitutes maintain identical electrical specifications, package dimensions, and environmental compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

RC5025F112CS (Samsung Electro-Mechanics)

Primary selection for new designs. Active production status with established supply chain. ROHS3 compliant with unlimited moisture sensitivity level. Suitable for general-purpose applications where automotive qualification is not required.

CRCW20101K10FKEF (Vishay Dale)

Recommended substitute for applications requiring automotive-grade components. Maintains active production status with AEC-Q200 qualification. Higher power rating (0.75W) provides thermal margin for the specified 0.667W application. Identical electrical and environmental specifications. Tape & Reel packaging format compatible with automated assembly processes.

ERJ-12SF1101U (Panasonic Electronic Components)

Alternative substitute with AEC-Q200 automotive qualification. Designated as "Not For New Designs" by manufacturer. Suitable only for replacement or legacy system applications where existing design validation has been completed. Higher power rating (0.75W) and identical electrical specifications maintain functional compatibility. Tape & Reel packaging format compatible with automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can CRCW20101K10FKEF or ERJ-12SF1101U be used as direct replacements for RC5025F112CS?

A: Yes. Both substitute parts maintain identical resistance value (1.1 kOhms), tolerance (±1%), package format (2010 / 5025 Metric), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The higher power rating (0.75W versus 0.667W) does not prevent substitution in applications designed for the original component.

Q: What is the difference in physical dimensions between the main part and substitutes?

A: The length and width dimensions are identical across all three parts (0.197" L x 0.098" W / 5.00mm x 2.50mm). Maximum seated height differs slightly: RC5025F112CS measures 0.026" (0.66mm) while both substitutes measure 0.028" (0.70mm). This 0.002" (0.04mm) difference is within standard PCB assembly tolerances and does not affect mechanical compatibility.

Q: Are there compliance or certification differences between these parts?

A: RC5025F112CS and CRCW20101K10FKEF are both ROHS3 compliant with active production status. ERJ-12SF1101U is also ROHS3 compliant but carries a "Not For New Designs" designation. All three parts have unlimited moisture sensitivity level (MSL 1) and REACH unaffected status. CRCW20101K10FKEF and ERJ-12SF1101U include AEC-Q200 automotive qualification; RC5025F112CS does not.

Q: Which substitute should be selected for new product designs?

A: CRCW20101K10FKEF is the recommended substitute for new designs. It maintains active production status and provides automotive-grade qualification if required by application specifications. ERJ-12SF1101U should not be used for new designs due to its "Not For New Designs" status.

Q: Are the packaging formats compatible with existing assembly equipment?

A: RC5025F112CS is supplied in standard packaging format. Both CRCW20101K10FKEF and ERJ-12SF1101U are supplied in Tape & Reel (TR) format, which is standard for automated pick-and-place assembly equipment. The 2010 (5025 Metric) package footprint is identical across all three parts, ensuring compatibility with existing PCB designs and assembly processes.

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

A: The substitute parts are rated for 0.75W (3/4W) compared to the original 0.667W (2/3W). This higher rating provides additional thermal margin and does not affect electrical performance in applications designed for the lower power specification. The component will operate within normal temperature ranges with reduced thermal stress.
