RC5025F821CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F821CS is an 820 Ohms ±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 features moisture-resistant construction suitable for industrial and consumer electronics applications. The part maintains Active product status with 791 units currently in stock.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the critical parameters: resistance value, tolerance, power rating, package dimensions, and operating temperature range. Alternative sources ensure supply chain flexibility and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F821CS is determined by strict alignment with the following critical parameters:

Electrical Parameters:

• Resistance value: 820 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match or superior range required)

Mechanical Parameters:

• Package / Case: 2010 (5025 Metric) (exact match required)
• Physical Dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm) (exact match required)
• Number of Terminations: 2 (exact match required)

Composition & Features:

• Composition: Thick Film (exact match required)
• Moisture Resistant: Yes (exact match required)

Compliance & Regulatory:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The power rating may exceed the original specification (0.667W minimum) without affecting substitution validity, as higher power ratings provide design margin and thermal performance enhancement.

Engineering Selection Recommendations

RC5025F821CS (Samsung Electro-Mechanics) - Primary Selection

The RC5025F821CS remains the primary component choice when Samsung supply is available. Active product status, established manufacturing process, and current inventory of 791 units support immediate procurement. ROHS3 compliance and REACH unaffected status confirm regulatory alignment for global applications.

RC2010FK-07820RL (YAGEO) - Qualified Substitute

The RC2010FK-07820RL qualifies as a direct substitute when Samsung supply is constrained or unavailable. This YAGEO component maintains identical electrical specifications (820 Ohms ±1%, ±100ppm/°C) and mechanical compatibility (2010 package, 5.00mm x 2.50mm dimensions). The elevated power rating (0.75W versus 0.667W) provides thermal performance enhancement without circuit redesign. Active product status and 7274 units in inventory ensure supply continuity. ROHS3 compliance and REACH unaffected status maintain regulatory equivalence.

Both components are suitable for direct PCB footprint substitution without layout modification. Thermal design margins improve with the YAGEO substitute due to higher power dissipation capability.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-07820RL replace RC5025F821CS in existing designs?

A: Yes. Both components share identical resistance (820 Ohms), tolerance (±1%), package dimensions (2010/5025 Metric, 5.00mm x 2.50mm), and operating temperature range (-55°C ~ 155°C). The YAGEO part's higher power rating (0.75W versus 0.667W) provides additional thermal margin. No PCB layout changes are required.

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

A: The RC2010FK-07820RL is rated for 0.75W (3/4W) compared to the RC5025F821CS at 0.667W (2/3W). This 12.5% power rating increase does not affect electrical performance but improves thermal stability under continuous operation. Circuits designed for the Samsung part operate safely with the YAGEO substitute.

Q: Are both parts RoHS compliant?

A: Yes. Both RC5025F821CS and RC2010FK-07820RL are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for EU and global markets.

Q: What is the Moisture Sensitivity Level (MSL) rating?

A: Both components carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard storage conditions apply without special desiccant packaging requirements.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.197" L x 0.098" W (5.00mm x 2.50mm) with maximum seated heights of 0.026" (0.66mm and 0.65mm respectively). These dimensions are interchangeable for PCB footprint compatibility.

Q: What packaging formats are available?

A: RC5025F821CS is supplied in standard packaging. RC2010FK-07820RL is available in Tape & Reel (TR) format, suitable for automated assembly processes.

Q: Do both parts have the same temperature coefficient?

A: Yes. Both components specify ±100ppm/°C temperature coefficient, ensuring identical frequency stability and resistance drift characteristics across the -55°C ~ 155°C operating range.
