RC5025F2210CS Equivalent & Substitute Parts

Part Overview

The RC5025F2210CS is a 221 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 2010 (5025 Metric) package format. This component is rated for 0.667W (2/3W) continuous power dissipation and operates across the temperature range of -55°C to 155°C. The part is classified as Active product status with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and package compatibility align with the main part's core parameters. Substitution becomes necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit higher power ratings or enhanced automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F2210CS are qualified based on the following substitution criteria:

Electrical Parameters (Must Match):

• Resistance value of 221 Ohms
• Tolerance of ±1% or tighter
• Temperature coefficient of ±100ppm/°C or better
• Operating temperature range of -55°C to 155°C or wider

Mechanical Parameters (Must Match):

• Package format: 2010 (5025 Metric)
• Physical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm)
• Two terminations (2-pin configuration)
• Thick film composition

Power Rating (Must Meet or Exceed):

• Minimum 0.667W (2/3W) continuous power dissipation

Compliance Parameters (Must Match):

• RoHS3 compliance
• MSL 1 (Unlimited) or better
• REACH Unaffected status

Substitute parts may include enhanced features such as automotive AEC-Q200 qualification or higher power ratings, provided all core electrical and mechanical parameters remain equivalent or superior.

Engineering Selection Recommendations

The CRCW2010221RFKEF from Vishay Dale qualifies as a direct substitute for the RC5025F2210CS based on matching electrical specifications, identical package geometry, and equivalent compliance certifications.

Substitution Advantages:

• Power rating of 0.75W exceeds the 0.667W requirement, providing additional thermal margin
• Automotive AEC-Q200 qualification provides enhanced reliability documentation for automotive applications
• Larger inventory availability (20,200 pcs vs. 711 pcs) supports supply chain continuity
• Identical RoHS3 and MSL 1 compliance maintains regulatory alignment

Substitution Considerations:

• Maximum seated height of 0.028" (0.70mm) versus 0.026" (0.66mm) represents a 0.04mm increase; verify PCB layout clearance for height-constrained applications
• Packaging format differs (Tape & Reel for substitute vs. standard packaging for main part); confirm reel compatibility with assembly equipment
• Automotive AEC-Q200 certification applies to substitute part; non-automotive applications do not require this qualification

Both parts maintain identical electrical performance across the full operating temperature range and deliver equivalent precision through ±1% tolerance and ±100ppm/°C temperature coefficient specifications.

Frequently Asked Questions (FAQ)

Q: Can the CRCW2010221RFKEF replace the RC5025F2210CS in all applications?

A: Yes, the CRCW2010221RFKEF meets or exceeds all core electrical and mechanical parameters. The substitute part delivers identical resistance value, tolerance, temperature coefficient, and operating temperature range. The higher power rating (0.75W vs. 0.667W) provides additional thermal capacity. Verify PCB layout clearance for the 0.028" maximum seated height.

Q: What is the significance of the 0.002" (0.04mm) height difference?

A: The CRCW2010221RFKEF has a maximum seated height of 0.028" compared to 0.026" for the RC5025F2210CS. This 0.002" difference is negligible for most applications but must be verified in designs with tight vertical clearance constraints, such as low-profile assemblies or applications with component stacking.

Q: Does the Automotive AEC-Q200 qualification of the substitute part affect non-automotive use?

A: No. AEC-Q200 qualification represents an additional quality and reliability standard that exceeds general industrial requirements. Non-automotive applications benefit from this enhanced qualification without penalty or incompatibility.

Q: Are the packaging formats interchangeable?

A: The RC5025F2210CS uses standard packaging while the CRCW2010221RFKEF is supplied in Tape & Reel (TR) format. Both formats contain identical components; however, assembly equipment compatibility must be confirmed. Tape & Reel format is standard for high-volume production environments.

Q: What compliance certifications apply to both parts?

A: Both the RC5025F2210CS and CRCW2010221RFKEF maintain RoHS3 compliance, MSL 1 (Unlimited) moisture sensitivity level, REACH Unaffected status, and EAR99 export classification. Regulatory requirements are fully satisfied by either part.

Q: Can the substitute part be used in temperature-sensitive applications?

A: Yes. Both parts operate across -55°C to 155°C with identical ±100ppm/°C temperature coefficient. Temperature performance is equivalent, and the substitute part is suitable for all temperature-dependent applications within this range.

Q: What is the basis for the 221 Ohm resistance value substitution?

A: Substitution requires exact resistance matching. The CRCW2010221RFKEF provides identical 221 Ohm nominal value with ±1% tolerance. No resistance value variation is permitted for direct substitution.
