RC5025F511CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F511CS is a 510 Ohms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.667W (2/3W) power dissipation in a 2010 (5025 Metric) surface mount package. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity level (MSL 1). The part is specified for applications requiring precision resistive elements in compact form factors with moisture resistance characteristics across the industrial temperature range of -55°C to 155°C.

Equivalent and substitute parts are identified to address inventory availability, supply chain continuity, or application-specific requirements where alternative manufacturers or enhanced specifications provide functional compatibility within the defined electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution of the RC5025F511CS is permissible with parts meeting the following criteria:

Mandatory Matching Parameters:

• Resistance value: 510 Ohms
• Tolerance: ±1%
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C minimum
• Moisture Resistance: Required
• RoHS3 Compliance: Required
• MSL Rating: 1 or equivalent

Allowable Variation:

• Power Rating: Equal to or greater than 0.667W (2/3W)
• Manufacturer: Different from Samsung Electro-Mechanics
• Packaging Format: May differ (Cut Tape, Digi-Reel, etc.)

The RC2010FK-07510RL from YAGEO qualifies as a substitute part due to identical electrical specifications, matching package dimensions, and enhanced power rating (0.75W vs. 0.667W), providing equivalent or superior performance in the specified application envelope.

Parameter Comparison

Engineering Selection Recommendations

The RC2010FK-07510RL from YAGEO is a qualified substitute for the RC5025F511CS based on the following engineering criteria:

Electrical Equivalence: Both parts maintain identical resistance value (510 Ohms), tolerance (±1%), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The substitute part's higher power rating (0.75W vs. 0.667W) provides enhanced thermal margin without altering circuit behavior.

Mechanical Compatibility: Package dimensions are identical (2010 / 5025 Metric, 5.00mm x 2.50mm), with seated height variation of 0.01mm (0.66mm vs. 0.65mm), which is within standard PCB assembly tolerances and does not affect placement or functionality.

Regulatory Compliance: Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating, ensuring equivalent environmental and regulatory standing.

Product Status: Both parts maintain Active product status, confirming ongoing manufacturer support and supply availability.

Selection between these parts should be based on supply chain availability, cost considerations, and packaging format requirements (standard packaging vs. Cut Tape / Digi-Reel options).

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-07510RL replace RC5025F511CS in existing designs without modification?

A: Yes. The substitute part meets all mandatory electrical and mechanical parameters. Identical resistance, tolerance, temperature coefficient, and package dimensions ensure direct functional equivalence. The higher power rating (0.75W vs. 0.667W) provides additional thermal headroom without circuit impact.

Q: Are there any height or footprint differences that affect PCB assembly?

A: Seated height differs by 0.01mm (0.66mm vs. 0.65mm), which is negligible for standard surface mount assembly processes. PCB footprints are identical for the 2010 (5025 Metric) package. No design or assembly modifications are required.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both RC5025F511CS and RC2010FK-07510RL carry MSL 1 (Unlimited) rating, indicating identical moisture handling requirements and storage conditions.

Q: What is the difference in power rating, and does it matter for my application?

A: The RC2010FK-07510RL is rated at 0.75W (3/4W) compared to the RC5025F511CS at 0.667W (2/3W). If your circuit requires only 0.667W or less, the substitute part operates with additional thermal margin, improving reliability. If your circuit requires higher power dissipation, the substitute accommodates this requirement. The higher rating does not negatively affect applications designed for the lower rating.

Q: Are there packaging format differences?

A: The RC5025F511CS is supplied in standard packaging, while RC2010FK-07510RL is available in Cut Tape (CT) and Digi-Reel® formats. Packaging format does not affect electrical or mechanical performance; selection depends on assembly line requirements and inventory management preferences.

Q: Do both parts comply with RoHS and REACH regulations?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component manufacturing and use.
