RC5025J240CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025J240CS is a 24 Ohm ±5% 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 classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). The part is specified for general-purpose applications requiring moisture-resistant thick film construction across an operating temperature range of -55°C to 155°C.

Equivalent and substitute parts are identified based on matching or exceeding the core electrical and mechanical specifications: resistance value, tolerance, power rating, package dimensions, and environmental compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025J240CS is determined by the following mandatory criteria:

Electrical Parameters:

• Resistance value must equal 24 Ohms
• Tolerance must be equal to or tighter than ±5%
• Power rating must be equal to or greater than 0.667W
• Temperature coefficient must be ±100ppm/°C or better
• Operating temperature range must encompass -55°C to 155°C

Mechanical Parameters:

• Package must be 2010 (5025 Metric) with identical footprint dimensions (0.197" L x 0.098" W / 5.00mm x 2.50mm)
• Composition must be thick film
• Moisture resistance feature must be present

Compliance Parameters:

• RoHS3 compliance required
• MSL rating must be 1 (Unlimited) or equivalent
• REACH Unaffected status required

The substitute part AC2010FK-0724RL meets all mandatory criteria with the following distinctions: tighter tolerance (±1% versus ±5%), higher power rating (0.75W versus 0.667W), and automotive-grade AEC-Q200 qualification.

Parameter Comparison

Engineering Selection Recommendations

RC5025J240CS (Samsung Electro-Mechanics): This part is suitable for applications requiring standard tolerance (±5%) thick film resistors in the 2010 package format. Active product status and full RoHS3 compliance support continued use in new designs. The unlimited MSL rating and moisture-resistant construction provide reliability in standard industrial and consumer environments.

AC2010FK-0724RL (YAGEO) - Substitute: This part provides enhanced performance characteristics suitable for direct substitution. The tighter tolerance (±1%) offers improved circuit accuracy compared to the main part. The higher power rating (0.75W versus 0.667W) provides additional thermal margin. AEC-Q200 automotive qualification indicates enhanced reliability screening and quality assurance. Identical package dimensions, operating temperature range, and compliance certifications ensure mechanical and electrical compatibility. Tape & Reel packaging supports automated assembly processes.

Selection between these parts depends on application requirements: the main part for standard tolerance applications, the substitute for applications requiring tighter tolerance, higher power dissipation margin, or automotive-grade reliability.

Frequently Asked Questions (FAQ)

Q: Can AC2010FK-0724RL replace RC5025J240CS in existing designs?

A: Yes. Both parts share identical resistance value (24 Ohms), package dimensions (2010 / 5025 Metric), operating temperature range (-55°C to 155°C), and compliance certifications (RoHS3, MSL 1). The substitute offers tighter tolerance (±1% versus ±5%) and higher power rating (0.75W versus 0.667W), making it functionally compatible and performance-enhanced.

Q: What are the key differences between these parts?

A: The primary differences are tolerance grade (±1% versus ±5%), power rating (0.75W versus 0.667W), and automotive qualification (AEC-Q200 for the substitute). The substitute part is manufactured by YAGEO rather than Samsung Electro-Mechanics. All other electrical and mechanical parameters are equivalent.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 2010 (5025 Metric) package with dimensions of 0.197" L x 0.098" W (5.00mm x 2.50mm). Maximum seated height is 0.66mm for the main part and 0.65mm for the substitute, representing negligible difference. PCB footprints are identical.

Q: Does the substitute part require different handling or storage?

A: No. Both parts have MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture control requirements during storage or handling. Standard component storage conditions apply to both.

Q: What is the significance of AEC-Q200 qualification on the substitute?

A: AEC-Q200 is an automotive industry standard qualification indicating the part has undergone enhanced reliability testing and quality screening. This certification does not restrict use in non-automotive applications; it indicates higher quality assurance standards were applied during manufacturing.

Q: Can the main part replace the substitute in new designs?

A: Functionally yes, but with considerations. The main part has wider tolerance (±5% versus ±1%), which may be unsuitable for applications requiring tight resistance accuracy. The lower power rating (0.667W versus 0.75W) provides less thermal margin. For new designs, the substitute part is preferred when tolerance and power margin are design factors.

Q: Are there packaging format differences?

A: Yes. The main part is supplied in bulk packaging, while the substitute is supplied in Tape & Reel (TR) format. Tape & Reel is standard for automated assembly processes. Bulk packaging may require manual handling or custom reeling for automated placement equipment.
