RC5025F393CS Equivalent & Substitute Parts

Part Overview

The RC5025F393CS is a 39 kOhm ±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 full RoHS3 compliance with Moisture Sensitivity Level 1 (unlimited shelf life). Equivalent and substitute parts are identified to provide design flexibility, inventory alternatives, and sourcing options while maintaining electrical and mechanical compatibility within specified parameters.

Substitute Part Grouping Explanation

Substitute parts for the RC5025F393CS are identified based on strict electrical and mechanical parameter matching. The substitution logic requires:

Mandatory Matching Parameters:

• Resistance value: 39 kOhms (exact match)
• Tolerance: ±1% (exact match)
• Package / Case: 2010 (5025 Metric) (exact match)
• Composition: Thick Film (exact match)
• Temperature Coefficient: ±100ppm/°C (exact match)
• Operating Temperature Range: -55°C to 155°C (exact match)
• Moisture Resistance: Yes (exact match)
• RoHS Status: ROHS3 Compliant (exact match)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match)

Allowable Variation:

• Power Rating: Substitute parts may have equal or higher power rating than the main part (0.667W minimum). Higher power ratings provide thermal margin and are electrically compatible in circuits designed for the original part's power specification.

The RC2010FK-0739KL from YAGEO meets all mandatory parameters and provides an increased power rating of 0.75W (3/4W), which is compatible with applications requiring the RC5025F393CS.

Engineering Selection Recommendations

RC5025F393CS (Samsung Electro-Mechanics)

Select this part when the original Samsung sourcing specification is required or when inventory from the current supplier is available. The part is Active status with full RoHS3 compliance and MSL 1 rating, supporting unlimited shelf life storage. This component is suitable for applications where the 0.667W power rating is sufficient and Samsung supply chain continuity is prioritized.

RC2010FK-0739KL (YAGEO)

Select this part as a direct substitute when Samsung supply is unavailable or when higher thermal margin is required. The YAGEO equivalent provides identical electrical characteristics (39 kOhms ±1%, ±100ppm/°C) and mechanical compatibility (2010 package, identical dimensions) with an increased power rating of 0.75W. This part carries Active status, ROHS3 compliance, and MSL 1 rating. The higher power rating provides additional thermal headroom in power-dissipation-sensitive applications while maintaining full compatibility with circuits designed for the original part. Both parts are supplied in standard packaging formats and support equivalent lead times and availability.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-0739KL replace RC5025F393CS in existing designs?

A: Yes. The RC2010FK-0739KL is electrically and mechanically compatible. Both parts share identical resistance (39 kOhms), tolerance (±1%), package (2010), temperature coefficient (±100ppm/°C), and operating range (-55°C to 155°C). The substitute part has a higher power rating (0.75W vs. 0.667W), which is compatible with circuits designed for the original part.

Q: Are there physical differences between these parts?

A: Physical dimensions are identical: 0.197" L x 0.098" W (5.00mm x 2.50mm). Maximum seated height differs negligibly (0.66mm vs. 0.65mm), which is within standard PCB assembly tolerances and does not affect placement or functionality.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RC5025F393CS and RC2010FK-0739KL are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are REACH unaffected. Both support identical regulatory and environmental requirements.

Q: What is the significance of the higher power rating on the substitute part?

A: The RC2010FK-0739KL's 0.75W rating (versus 0.667W on the original) indicates greater thermal dissipation capacity. This provides additional safety margin in applications approaching the original part's power limit and does not affect electrical performance in circuits designed for the lower-rated part.

Q: Are packaging formats different between these parts?

A: The RC5025F393CS is supplied in standard packaging (not specified in detail). The RC2010FK-0739KL is supplied in Tape & Reel (TR) format. Both are standard industry formats compatible with automated assembly equipment. Verify packaging requirements for your procurement and assembly process.

Q: Can these parts be used interchangeably in production?

A: Yes, within the constraints of your supply chain and quality documentation. Both parts are Active status with identical electrical specifications and mechanical compatibility. Substitution requires verification that your design documentation and bill of materials support cross-manufacturer sourcing or that engineering change documentation is completed.
