RC5025F1871CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F1871CS is a 1.87 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated for 0.667W (2/3W) power dissipation in a 2010 (5025 Metric) package. 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 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, extended lead times, or specific application requirements such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F1871CS is determined by strict adherence to the following criteria:

Mandatory Matching Parameters:

• Resistance value: 1.87 kOhms
• Tolerance: ±1%
• Package footprint: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100 ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

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 envelope.

The identified substitute parts meet all mandatory parameters and maintain full electrical and mechanical compatibility with the RC5025F1871CS in applications where the original part is specified.

Parameter Comparison

Engineering Selection Recommendations

CRCW20101K87FKEF (Vishay Dale) is the primary substitute for new designs and ongoing production. 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 match the RC5025F1871CS specification. Packaging is supplied as Tape & Reel (TR) with 4791 units in current inventory.

ERJ-12SF1871U (Panasonic Electronic Components) is functionally equivalent but carries "Not For New Designs" product status. This designation indicates the manufacturer has discontinued active development for this part number. While electrically and mechanically compatible with identical 0.75W power rating and AEC-Q200 qualification, this part should be reserved for legacy system maintenance or replacement applications only. Current inventory shows 5681 units available.

For applications requiring the original Samsung Electro-Mechanics RC5025F1871CS, the CRCW20101K87FKEF provides the most suitable long-term alternative with Active status and equivalent performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can CRCW20101K87FKEF replace RC5025F1871CS in existing designs?

A: Yes. Both parts share identical resistance (1.87 kOhms), tolerance (±1%), package (2010/5025 Metric), composition (Thick Film), temperature coefficient (±100 ppm/°C), and operating range (-55°C to 155°C). The CRCW20101K87FKEF provides higher power rating (0.75W vs. 0.667W), which is compatible with applications designed for the original part.

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

A: CRCW20101K87FKEF (Vishay Dale) maintains Active product status, while ERJ-12SF1871U (Panasonic) is marked "Not For New Designs." Both are electrically and mechanically identical. The Vishay part is recommended for new designs; the Panasonic part is suitable for legacy system support only.

Q: Are the substitute parts available in the same packaging format?

A: The RC5025F1871CS is supplied in standard packaging (not specified as Tape & Reel). Both substitute parts are supplied as Tape & Reel (TR), which is standard for high-volume SMD component distribution. Reel packaging is compatible with automated assembly processes.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are REACH Unaffected. The substitute parts additionally carry AEC-Q200 automotive qualification, which exceeds the original part's compliance profile.

Q: Can ERJ-12SF1871U be used in new product designs?

A: No. The "Not For New Designs" status indicates Panasonic has discontinued active support for this part. Use CRCW20101K87FKEF for new designs. ERJ-12SF1871U is appropriate only for replacement or maintenance of existing systems.

Q: Are there dimensional differences between the parts?

A: All three parts use the 2010 (5025 Metric) package with identical length and width (0.197" L × 0.098" W / 5.00mm × 2.50mm). Maximum seated height varies slightly: RC5025F1871CS at 0.026" (0.66mm), while both substitutes are 0.028" (0.70mm). This 0.002" difference is within standard PCB assembly tolerances.
