Substitute Part Grouping Explanation

Substitute parts for the RC5025F301CS are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

Mandatory Matching Criteria:

• Resistance value: 300 Ohms
• 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 may have equal or higher power ratings (0.75W or greater) while maintaining all other electrical and mechanical specifications

The identified substitutes RC2010FK-07300RL (YAGEO) and RMCF2010FT300R (Stackpole Electronics Inc) meet all mandatory criteria with upgraded power ratings of 0.75W (3/4W), providing enhanced thermal margin in applications where the original 0.667W rating is marginal.

Parameter Comparison

Engineering Selection Recommendations

RC2010FK-07300RL (YAGEO) is suitable for direct substitution in applications requiring standard industrial-grade thick film resistors. This part maintains identical electrical specifications to the RC5025F301CS while providing a 0.083W power rating increase (0.75W vs. 0.667W). ROHS3 compliance and unlimited MSL rating ensure compatibility with standard PCB assembly and storage protocols. Packaging in Tape & Reel format supports automated assembly processes.

RMCF2010FT300R (Stackpole Electronics Inc) is designated for applications requiring automotive-grade qualification. This part carries AEC-Q200 certification, indicating compliance with automotive reliability standards. The 0.75W power rating and identical electrical specifications make it suitable for automotive and high-reliability industrial applications. Marginal height variation (0.028" vs. 0.026") remains within standard PCB design tolerances for 2010 package footprints.

Both substitute parts are Active status components with established supply availability and full compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-07300RL replace RC5025F301CS in any application?

A: RC2010FK-07300RL is electrically and mechanically compatible with RC5025F301CS. The 0.083W power rating increase provides additional thermal margin. Verify PCB layout accommodates the 0.65mm seated height (vs. 0.66mm original). No functional limitations exist for standard industrial applications.

Q: What is the difference between RC2010FK-07300RL and RMCF2010FT300R?

A: Both parts share identical electrical specifications (300 Ohms ±1%, 0.75W, ±100ppm/°C, -55°C ~ 155°C). RMCF2010FT300R includes AEC-Q200 automotive qualification; RC2010FK-07300RL is standard industrial-grade. RMCF2010FT300R seated height is 0.028" (vs. 0.026" original). Select RMCF2010FT300R for automotive applications; RC2010FK-07300RL for general industrial use.

Q: Are there any package compatibility issues when substituting these parts?

A: All three parts use identical 2010 (5025 Metric) package footprints with 0.197" L x 0.098" W dimensions. Seated height variations (0.026" to 0.028") are within standard PCB design tolerances and do not affect footprint compatibility or solder joint integrity.

Q: Do substitute parts maintain the same moisture sensitivity level?

A: Yes. RC2010FK-07300RL and RMCF2010FT300R both carry MSL 1 (Unlimited) rating, identical to RC5025F301CS. No additional moisture control measures are required during storage or assembly.

Q: Are all three parts ROHS3 compliant?

A: Yes. RC5025F301CS, RC2010FK-07300RL, and RMCF2010FT300R are all ROHS3 compliant with REACH Unaffected status and EAR99 export classification.

Q: What is the primary reason to substitute RC5025F301CS?

A: Substitution is driven by supply availability, lead time requirements, or application-specific needs. RC2010FK-07300RL offers higher power rating for thermal margin. RMCF2010FT300R provides automotive qualification for regulated applications. All maintain identical core electrical specifications.
