RC5025F390CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F390CS is a 39 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.667W (2/3W) power dissipation in the 2010 (5025 Metric) package format. This component is classified as Active product status and is ROHS3 compliant with MSL Level 1 moisture sensitivity rating. Substitute parts are identified when inventory constraints, lead time requirements, or design flexibility necessitate alternative sourcing while maintaining electrical and mechanical compatibility within specified tolerance parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F390CS is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 39 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 2010 (5025 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: MSL 1 (exact match required)

Allowable Variation Parameters:

• Power Rating: Substitute parts may exceed the main part power rating (0.667W minimum acceptable). Higher power ratings provide enhanced thermal margin and are electrically compatible in applications designed for the original specification.
• Manufacturer: Different manufacturers permitted when all electrical and mechanical parameters align.
• Packaging Format: Tape & Reel (TR) or alternative packaging acceptable when component specifications remain identical.

The RC2010FK-0739RL from YAGEO qualifies as a substitute based on full parameter alignment with allowable variation in power rating (0.75W vs. 0.667W).

Parameter Comparison

Engineering Selection Recommendations

RC5025F390CS (Samsung Electro-Mechanics): Primary selection when Samsung sourcing is specified or preferred. Active product status with established supply chain. ROHS3 and REACH compliant. MSL 1 rating permits standard handling procedures without moisture bake requirements.

RC2010FK-0739RL (YAGEO): Functionally equivalent substitute with identical electrical specifications and physical dimensions. Higher power rating (0.75W vs. 0.667W) provides additional thermal headroom in applications operating near maximum dissipation limits. Active product status with confirmed inventory availability. ROHS3 and REACH compliant. MSL 1 rating permits standard handling procedures. Suitable for direct replacement in PCB assembly processes without design modification.

Both parts satisfy identical regulatory compliance requirements and environmental operating specifications. Selection between these parts is determined by supplier availability, procurement lead times, and inventory status rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-0739RL replace RC5025F390CS in existing designs?

A: Yes. The RC2010FK-0739RL is electrically and mechanically compatible. Both components share identical resistance value (39 Ohms), tolerance (±1%), package format (2010/5025 Metric), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). The substitute part's higher power rating (0.75W vs. 0.667W) does not create incompatibility; it provides enhanced thermal capacity.

Q: What are the physical dimension differences between these parts?

A: Physical dimensions are effectively identical. Both parts measure 0.197" L x 0.098" W (5.00mm x 2.50mm) with maximum seated heights of 0.026" (0.66mm for Samsung, 0.65mm for YAGEO). These negligible height variations do not affect PCB assembly or component placement.

Q: Are both parts ROHS3 compliant?

A: Yes. Both RC5025F390CS and RC2010FK-0739RL are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the significance of MSL 1 rating for both parts?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake requirements. Both components can be stored and handled using standard procedures without special moisture control measures, simplifying inventory management and assembly logistics.

Q: Can these parts be used interchangeably in tape and reel format?

A: RC5025F390CS is supplied in standard packaging format. RC2010FK-0739RL is supplied in Tape & Reel (TR) format. Both formats contain identical components; packaging format selection depends on assembly equipment compatibility and procurement preferences.

Q: What tolerance specifications apply to both substitute parts?

A: Both parts maintain ±1% tolerance on the 39 Ohm resistance value, ensuring equivalent precision performance in circuit applications requiring tight tolerance specifications.
