Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the RC5025F32R4CS is based on the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value must be exactly 32.4 Ohms
• Tolerance must be ±1% or tighter
• Temperature coefficient must be ±100ppm/°C or better
• Operating temperature range must encompass -55°C ~ 155°C

Mechanical Compatibility Requirements:

• Package type must be 2010 (5025 Metric)
• Physical dimensions must be compatible with PCB footprint
• Number of terminations must be 2

Regulatory & Environmental Requirements:

• RoHS3 compliance mandatory
• Moisture Sensitivity Level must be MSL 1 or equivalent
• REACH status must be unaffected or compliant

Power Rating Consideration:

• Substitute parts may have equal or higher power ratings (0.667W or greater)
• Higher power ratings provide additional thermal margin without affecting circuit function

The RMCF2010FT32R4 meets all substitution criteria with identical electrical specifications and package compatibility, with the additional benefit of AEC-Q200 automotive qualification and 0.75W power rating.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (RC5025F32R4CS - Samsung Electro-Mechanics): Select this part when Samsung supply chain is preferred or when specific design validation has been performed against this manufacturer. Active product status ensures continued availability. RoHS3 compliance and MSL 1 rating support standard manufacturing and storage protocols.

Substitute Selection (RMCF2010FT32R4 - Stackpole Electronics Inc): Select this part when Stackpole supply is more favorable or when automotive-grade components are required. The AEC-Q200 qualification provides additional reliability assurance for automotive and high-reliability applications. The 0.75W power rating offers increased thermal margin compared to the 0.667W primary part. All electrical and mechanical parameters are equivalent or superior. RoHS3 and MSL 1 compliance maintain regulatory alignment.

Substitution Validity: Both parts are Active status components with identical electrical specifications, package compatibility, and regulatory compliance. The 0.04mm height difference (0.66mm vs 0.70mm) is within standard PCB assembly tolerances and does not affect functionality or placement.

Frequently Asked Questions (FAQ)

Q: Can RMCF2010FT32R4 be used as a direct replacement for RC5025F32R4CS?

A: Yes. Both parts have identical resistance (32.4 Ohms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and 2010 package dimensions. The RMCF2010FT32R4 has a higher power rating (0.75W vs 0.667W), which is acceptable for substitution as it provides additional thermal capability without affecting circuit performance.

Q: What is the significance of the power rating difference?

A: The RC5025F32R4CS is rated for 0.667W and the RMCF2010FT32R4 for 0.75W. A higher power rating indicates greater thermal dissipation capability. Substituting a higher-rated part does not degrade performance; it only provides additional margin. The actual power dissipation in the circuit is determined by the resistance value and applied current, not the part rating.

Q: Are there any height compatibility issues?

A: The seated height difference is 0.04mm (0.66mm vs 0.70mm). This falls within standard PCB assembly tolerances and does not affect component placement, soldering, or functionality. Both parts are compatible with standard 2010 package footprints.

Q: Does AEC-Q200 qualification on the Stackpole part affect compatibility?

A: No. AEC-Q200 is an automotive qualification standard that indicates additional reliability testing and quality assurance. It does not change electrical or mechanical specifications. A part with AEC-Q200 qualification can be used in non-automotive applications without any negative effects.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RC5025F32R4CS and RMCF2010FT32R4 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. They meet current regulatory requirements for hazardous substance restrictions and can be used interchangeably from a compliance perspective.

Q: What packaging formats are available?

A: The RC5025F32R4CS is supplied in standard packaging (not specified as Tape & Reel). The RMCF2010FT32R4 is supplied in Tape & Reel (TR) format, which is standard for automated assembly. Tape & Reel packaging is compatible with standard pick-and-place equipment and does not affect component performance.

Q: Can these parts be mixed in the same production batch?

A: Yes. Both parts meet identical electrical specifications and package requirements. However, component traceability and design documentation should reflect which manufacturer is used in specific units for warranty and failure analysis purposes.
