Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC5025F333CS is determined by strict equivalence in the following critical parameters:

Mandatory Equivalence Parameters:

• Resistance value: 33 kOhms
• Tolerance: ±1%
• Package format: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Power rating: Substitute parts may have equal or higher power ratings (0.75W or greater)
• Manufacturer: Different manufacturers with equivalent specifications
• Packaging format: Tape & Reel (TR) acceptable for equivalent parts
• Additional certifications: Automotive AEC-Q200 qualification is an enhancement, not a restriction

The identified substitute parts maintain full electrical and mechanical compatibility with the RC5025F333CS while offering either increased power handling capability or enhanced reliability certifications.

Parameter Comparison

Engineering Selection Recommendations

RC5025F333CS (Samsung Electro-Mechanics) - Primary Part

Use this part for standard applications requiring a 33 kOhms ±1% resistor in the 2010 package format. The 0.667W power rating is suitable for general-purpose signal conditioning and biasing circuits. Active production status and high inventory availability (1126 units) support consistent supply. ROHS3 compliance and unlimited moisture sensitivity rating ensure environmental and reliability standards.

RC2010FK-0733KL (YAGEO) - Upgrade Substitute

This part provides direct substitution with increased power handling capability (0.75W versus 0.667W). The higher power rating offers design margin for applications approaching the thermal limits of the original specification. YAGEO RC_L series maintains identical electrical characteristics and package dimensions. Tape & Reel packaging supports automated assembly processes. ROHS3 compliance and unlimited MSL rating match the original part. High inventory availability (8407 units) ensures supply continuity.

RMCF2010FT33K0 (Stackpole Electronics Inc) - Automotive-Grade Substitute

This part is suitable for applications requiring automotive-grade reliability. The RMCF series carries AEC-Q200 qualification, indicating compliance with automotive industry reliability and environmental stress testing standards. Power rating of 0.75W provides equivalent thermal margin to the YAGEO alternative. Physical dimensions remain compatible with the 2010 package format. ROHS3 compliance and unlimited MSL rating are maintained. Lower inventory availability (697 units) reflects specialized automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-0733KL and RMCF2010FT33K0 be used interchangeably with RC5025F333CS?

A: Both substitute parts are electrically and mechanically compatible with the RC5025F333CS. All three parts share identical resistance (33 kOhms), tolerance (±1%), package format (2010), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The substitute parts feature higher power ratings (0.75W) and maintain ROHS3 compliance and unlimited moisture sensitivity. Selection depends on application-specific requirements such as thermal margin or automotive certification needs.

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

A: The RC5025F333CS is rated for 0.667W continuous power dissipation, while RC2010FK-0733KL and RMCF2010FT33K0 are rated for 0.75W. The higher rating in the substitute parts provides additional thermal headroom. In applications where the resistor dissipates power near the original 0.667W limit, the substitute parts offer improved reliability margin. The physical package dimensions remain identical across all three parts.

Q: Are there packaging format differences between these parts?

A: The RC5025F333CS is supplied in standard packaging format. RC2010FK-0733KL and RMCF2010FT33K0 are supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. All three parts use the identical 2010 (5025 Metric) package case. Tape & Reel packaging does not affect electrical or mechanical compatibility; it only impacts handling and assembly methodology.

Q: What does AEC-Q200 qualification mean for RMCF2010FT33K0?

A: AEC-Q200 is an automotive industry standard qualification that certifies component reliability under automotive environmental and stress conditions. RMCF2010FT33K0 carries this certification, making it suitable for automotive applications requiring proven reliability in temperature cycling, vibration, and humidity exposure. The RC5025F333CS and RC2010FK-0733KL do not carry this specific automotive qualification but remain suitable for non-automotive applications.

Q: Can these parts be used in high-temperature applications?

A: All three parts operate across the identical temperature range of -55°C to 155°C with a temperature coefficient of ±100ppm/°C. This range supports industrial and automotive applications. The temperature coefficient indicates that resistance value changes by ±100 parts per million for each degree Celsius change in operating temperature. Selection among the three parts is not determined by temperature range compatibility.

Q: What is Moisture Sensitivity Level 1 (Unlimited)?

A: Moisture Sensitivity Level 1 (MSL 1) indicates unlimited shelf life without moisture-related degradation. All three parts carry this rating, meaning they do not require special moisture-controlled storage conditions and can be stored indefinitely under normal conditions. This simplifies inventory management and supply chain handling.

Q: Are all three parts ROHS3 compliant?

A: Yes, all three parts—RC5025F333CS, RC2010FK-0733KL, and RMCF2010FT33K0—are ROHS3 compliant. ROHS3 compliance certifies that the parts do not contain restricted hazardous substances as defined by the Restriction of Hazardous Substances directive. This compliance is mandatory for applications in regulated markets and industries.
