RC5025F6191CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F6191CS is a 6.19 kOhms ±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 classified as Active product status with moisture resistant construction and unlimited moisture sensitivity level (MSL 1).

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 RC5025F6191CS is determined by strict adherence to the following criteria:

Mandatory Matching Parameters:

• Resistance value: 6.19 kOhms
• Tolerance: ±1%
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 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 footprint.

Identified Substitute Parts:

1. CRCW20106K19FKEF (Vishay Dale) – 0.75W rated, AEC-Q200 automotive qualified
2. ERJ-12SF6191U (Panasonic Electronic Components) – 0.75W rated, AEC-Q200 automotive qualified, Not For New Designs status

Both substitute parts maintain identical electrical specifications, mechanical compatibility, and environmental compliance while offering higher power ratings and automotive qualification certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: CRCW20106K19FKEF (Vishay Dale)

This part is the preferred substitute for new designs and ongoing production. It maintains full electrical and mechanical compatibility with the RC5025F6191CS while offering AEC-Q200 automotive qualification and higher power rating (0.75W). Product status is Active, ensuring long-term availability and supply chain stability.

Secondary Substitute: ERJ-12SF6191U (Panasonic Electronic Components)

This part provides equivalent electrical and mechanical specifications with AEC-Q200 automotive qualification. However, its Product Status designation as "Not For New Designs" restricts its use to legacy applications, maintenance, or repair scenarios where existing inventory must be maintained. New design implementations should prioritize CRCW20106K19FKEF.

Selection Criteria:

• For new designs requiring automotive qualification: CRCW20106K19FKEF
• For legacy system maintenance: ERJ-12SF6191U (if existing designs specify this part)
• For general industrial applications without automotive requirements: RC5025F6191CS (original) or CRCW20106K19FKEF (higher power rating option)

All three parts are ROHS3 compliant and maintain identical resistance, tolerance, temperature coefficient, and operating temperature specifications.

Frequently Asked Questions (FAQ)

Q: Can CRCW20106K19FKEF replace RC5025F6191CS in existing designs?

A: Yes. CRCW20106K19FKEF is a direct substitute. Both parts share identical resistance (6.19 kOhms), tolerance (±1%), package footprint (2010/5025 Metric), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). The higher power rating (0.75W vs. 0.667W) provides additional thermal margin without affecting circuit performance.

Q: What is the difference between the 0.667W and 0.75W power ratings?

A: Both ratings are within the same 2010 package envelope. The 0.75W rating indicates higher power dissipation capability. In applications where the RC5025F6191CS operates below its 0.667W limit, the 0.75W substitute will operate with lower junction temperature, improving reliability and component lifespan.

Q: Why is ERJ-12SF6191U marked "Not For New Designs"?

A: This designation indicates the manufacturer (Panasonic) has discontinued active development and promotion of this part number for new applications. Existing inventory remains available for legacy system support. New designs should specify CRCW20106K19FKEF or RC5025F6191CS.

Q: Are there mechanical compatibility concerns with the height difference (0.66mm vs. 0.70mm)?

A: No. The maximum seated height difference of 0.04mm (0.66mm to 0.70mm) is within standard PCB assembly tolerances and does not affect mechanical fit or electrical performance in standard 2010 package applications.

Q: Do all three parts meet the same compliance standards?

A: Yes. RC5025F6191CS, CRCW20106K19FKEF, and ERJ-12SF6191U are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. CRCW20106K19FKEF and ERJ-12SF6191U additionally carry AEC-Q200 automotive qualification.

Q: What is the impact of ±100ppm/°C temperature coefficient on circuit performance?

A: All three parts share identical temperature coefficient specifications. This parameter determines resistance drift across the operating temperature range (-55°C ~ 155°C). The ±100ppm/°C specification is consistent across all substitutes, ensuring equivalent temperature-dependent behavior.
