Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC5025J515CS is permissible when the following criteria are met:

Critical Parameters for Substitution:

• Resistance value must be 5.1 MOhms
• Package must be 2010 (5025 Metric)
• Composition must be thick film
• Temperature coefficient must be ±100ppm/°C
• Operating temperature range must be -55°C to 155°C
• Number of terminations must be 2

Allowable Parameter Variations:

• Tolerance may be tighter (±1% acceptable for ±5% requirement)
• Power rating may be equal or higher (0.75W acceptable for 0.667W requirement)
• Additional certifications (AEC-Q200) do not prevent substitution
• Packaging format may differ (Tape & Reel acceptable for bulk)

The RMCF2010FT5M10 from Stackpole Electronics Inc meets all critical parameters and represents a valid substitute with improved tolerance specification and higher power rating.

Parameter Comparison

Engineering Selection Recommendations

RC5025J515CS (Samsung Electro-Mechanics) is the primary component specification. Selection is appropriate for applications where the exact tolerance and power rating specifications are required, and Samsung supply chain availability is confirmed.

RMCF2010FT5M10 (Stackpole Electronics Inc) is a valid substitute when:

• The tighter ±1% tolerance is acceptable or beneficial to circuit performance
• The higher 0.75W power rating does not create thermal or space constraints
• The additional 0.002" (0.04mm) height does not conflict with PCB assembly clearances
• AEC-Q200 automotive qualification is not a requirement conflict
• Supply availability of the primary part is constrained

Both components are Active product status, ROHS3 compliant, and REACH unaffected. Selection between these parts should be based on availability, cost, and the specific tolerance and power requirements of the application circuit.

Frequently Asked Questions (FAQ)

Q: Can RMCF2010FT5M10 be used as a direct replacement for RC5025J515CS?

A: Yes, RMCF2010FT5M10 is electrically and mechanically compatible. The substitute has identical resistance value, package type, composition, temperature coefficient, and operating temperature range. The tighter tolerance (±1% vs ±5%) and higher power rating (0.75W vs 0.667W) are improvements that do not prevent substitution.

Q: What is the maximum height difference between these parts?

A: RC5025J515CS has a maximum seated height of 0.026" (0.66mm), while RMCF2010FT5M10 has a maximum seated height of 0.028" (0.70mm). The difference is 0.002" (0.04mm). Verify PCB assembly clearances if height-constrained applications are involved.

Q: Are both parts RoHS compliant?

A: Yes, both RC5025J515CS and RMCF2010FT5M10 are ROHS3 compliant and REACH unaffected.

Q: Does the ±1% tolerance of RMCF2010FT5M10 affect circuit performance compared to the ±5% tolerance of RC5025J515CS?

A: The tighter tolerance of RMCF2010FT5M10 provides improved resistance accuracy. This does not negatively affect circuits designed for the RC5025J515CS. Applications requiring ±5% tolerance will operate within specification with either part.

Q: What is the difference in power dissipation capability?

A: RC5025J515CS is rated at 0.667W (2/3W), while RMCF2010FT5M10 is rated at 0.75W (3/4W). The higher power rating of RMCF2010FT5M10 provides additional thermal margin and does not create compatibility issues in applications designed for the lower rating.

Q: Are there packaging format differences?

A: RC5025J515CS is supplied in standard packaging format. RMCF2010FT5M10 is supplied in Tape & Reel (TR) format. Both formats contain identical components; packaging format selection depends on assembly process requirements and order quantity.

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

A: Both parts are Active status components with identical operating temperature ranges and moisture sensitivity levels. RMCF2010FT5M10 carries AEC-Q200 automotive qualification. Selection should be based on specific application reliability requirements and qualification documentation.
