RC5025F4641CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F4641CS is a 4.64 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated for 0.667W (2/3W) power dissipation in a 2010 (5025 Metric) surface mount package. This component is currently in active production status with 1139 pieces available in inventory.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit alternative manufacturers meeting equivalent electrical and mechanical specifications. The ERJ-12SF4641U from Panasonic Electronic Components serves as a qualified substitute, though it carries a "Not For New Designs" status and features automotive-grade AEC-Q200 certification with slightly higher power rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F4641CS is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 4.64 kOhms (exact match required)
• Tolerance: ±1% (equal or tighter tolerance acceptable)
• Package designation: 2010 (5025 Metric) footprint
• Composition: Thick film construction
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C minimum coverage
• RoHS3 compliance status

Acceptable Variation Parameters:

• Power rating: Minimum 0.667W; higher ratings (0.75W, 1W, etc.) are acceptable as they provide additional thermal margin
• Moisture sensitivity level: MSL 1 or better
• Packaging format: Tape & Reel or bulk packaging formats are interchangeable for component selection purposes

The ERJ-12SF4641U qualifies as a substitute based on matching all mandatory parameters while exceeding the power rating specification (0.75W vs. 0.667W required). Physical dimensions remain within acceptable tolerance for PCB assembly compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Active Production and New Designs: The RC5025F4641CS remains the primary selection. It maintains active product status with established supply availability (1139 pieces in stock) and is explicitly designated for new design implementations. This component satisfies all regulatory requirements including ROHS3 compliance and REACH unaffected status.

For Replacement and Retrofit Applications: The ERJ-12SF4641U is electrically and mechanically compatible for direct substitution. All critical electrical parameters match the original specification. The higher power rating (0.75W vs. 0.667W) provides additional thermal margin without affecting circuit performance. Physical dimensions and footprint compatibility are confirmed.

Product Status Consideration: The ERJ-12SF4641U carries "Not For New Designs" designation, indicating Panasonic has transitioned this part to mature/legacy status. This classification does not affect substitution validity for existing designs or replacement scenarios but should be noted for long-term supply planning in new product development.

Certification Advantage: The ERJ-12SF4641U includes AEC-Q200 automotive qualification, providing enhanced reliability documentation suitable for automotive and high-reliability applications. This certification is not required for standard industrial applications but represents an additional quality assurance level.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF4641U be used as a direct replacement for RC5025F4641CS on existing PCBs?

A: Yes. Both components share identical 2010 (5025 Metric) footprints with matching land patterns. Physical dimensions (5.00mm × 2.50mm) are identical. Maximum seated height differs by 0.04mm (0.70mm vs. 0.66mm), which remains within standard PCB assembly tolerances and does not affect placement or soldering processes.

Q: Does the higher power rating of ERJ-12SF4641U (0.75W vs. 0.667W) create any compatibility issues?

A: No. Higher power ratings indicate greater thermal capability and do not negatively impact circuit operation. The substitute component can safely dissipate the same power level as the original while maintaining lower junction temperatures, improving reliability margins.

Q: What does "Not For New Designs" mean for the ERJ-12SF4641U?

A: This designation indicates Panasonic has classified this part as mature/legacy and is not actively promoting it for new product development. Existing inventory remains available for replacement and retrofit applications. For new designs, the RC5025F4641CS (active status) is the recommended primary selection.

Q: Are there any differences in temperature stability between these components?

A: No. Both components specify identical temperature coefficient (±100ppm/°C) and operating range (-55°C to 155°C). Resistance value stability over temperature is equivalent.

Q: What is the significance of AEC-Q200 certification on the ERJ-12SF4641U?

A: AEC-Q200 is an automotive industry qualification standard. This certification indicates the component has undergone enhanced reliability testing and is approved for automotive applications. For non-automotive applications, this certification provides additional assurance but is not a requirement for substitution.

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

A: Yes, from an electrical and mechanical standpoint. Both components meet identical electrical specifications and physical requirements. However, supply chain and quality documentation practices may require separate tracking depending on organizational procedures.

Q: What packaging formats are available for each part?

A: RC5025F4641CS is available in standard packaging (format not specified in inventory data). ERJ-12SF4641U is supplied in Tape & Reel (TR) format. Both formats are compatible with standard SMD assembly equipment.

Q: Are there any moisture handling differences between these components?

A: No. Both components specify MSL 1 (Unlimited moisture sensitivity level), indicating they can be stored and handled without special moisture control measures. Standard industrial storage conditions are acceptable for both parts.
