Substitute Part Grouping Explanation

Substitution logic for the RC5025F4640CS is based on the following criteria:

Electrical Equivalence: The substitute part must provide the same resistance value (464 Ohms) with tolerance of ±1% or better. Temperature coefficient must be ±100ppm/°C or superior to maintain circuit performance stability across the operating temperature range of -55°C to 155°C.

Mechanical Compatibility: The package designation must be 2010 (5025 Metric) to ensure identical PCB footprint and land pattern compatibility. Physical dimensions (0.197" L x 0.098" W / 5.00mm x 2.50mm) and termination count (2 terminations) must remain constant.

Power Rating: The substitute part must be rated at or above 0.667W. A higher power rating (such as 0.75W) is acceptable as it provides additional thermal margin without affecting circuit operation.

Composition and Features: Thick film construction is maintained. Additional features such as automotive qualification (AEC-Q200) do not disqualify a substitute but represent enhanced specifications.

Regulatory Compliance: Both parts must maintain ROHS3 compliance and MSL 1 rating. REACH Unaffected status and EAR99 ECCN classification are consistent across qualified substitutes.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (RC5025F4640CS): Use the Samsung Electro-Mechanics RC5025F4640CS when moisture-resistant thick film construction is the specified requirement and standard industrial applications are the target environment. This part maintains Active product status with full ROHS3 and REACH compliance.

Substitute Selection (RMCF2010FT464R): The Stackpole Electronics RMCF2010FT464R is a direct functional equivalent with the following distinctions: it carries AEC-Q200 automotive qualification, provides 0.75W power rating (exceeding the 0.667W requirement), and is available in higher inventory quantities. This substitute is suitable for applications requiring automotive-grade reliability or where higher power margin is beneficial. The marginal increase in seated height (0.028" versus 0.026") remains within standard PCB assembly tolerances.

Compliance Verification: Both parts maintain identical regulatory status: ROHS3 compliant, MSL 1 (Unlimited), REACH Unaffected, and EAR99 classification. Selection between these parts does not introduce compliance risk.

Frequently Asked Questions (FAQ)

Q: Can RMCF2010FT464R replace RC5025F4640CS in any application?

A: Yes, within the electrical and mechanical parameters specified. The RMCF2010FT464R provides equivalent resistance (464 Ohms ±1%), identical temperature coefficient (±100ppm/°C), matching operating temperature range (-55°C to 155°C), and identical package footprint (2010 / 5025 Metric). The higher power rating (0.75W versus 0.667W) and automotive qualification represent enhancements rather than limitations.

Q: Does the height difference (0.028" vs 0.026") affect PCB assembly?

A: No. The 0.002" (0.04mm) difference in seated height is within standard PCB assembly tolerances and does not affect reflow soldering, component placement, or clearance requirements for typical circuit board designs.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts share identical electrical specifications: 464 Ohms resistance, ±1% tolerance, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Thick film composition ensures equivalent frequency response and noise characteristics.

Q: What is the significance of AEC-Q200 qualification on the Stackpole part?

A: AEC-Q200 is an automotive industry standard qualification. It indicates the Stackpole part has undergone additional reliability testing and is approved for automotive applications. This qualification does not affect performance in non-automotive applications but provides additional assurance of manufacturing quality and consistency.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. Both parts are pin-compatible (2 terminations), footprint-compatible (2010 package), and electrically equivalent. No circuit redesign or PCB layout modification is required for substitution.

Q: What packaging formats are available?

A: RC5025F4640CS is supplied in standard packaging (specific format not detailed in specifications). RMCF2010FT464R is available in Tape & Reel (TR) format, which is standard for automated assembly processes.

Q: Are both parts currently in production?

A: Yes. Both parts maintain Active product status, indicating current manufacturing and availability through authorized distributors.
