Equivalent & Substitute Parts for RC5025J274CS

Part Overview

The RC5025J274CS is a 270 kOhms ±5% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.667W (2/3W) power dissipation in a 2010 (5025 Metric) package. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). The part is designed for applications requiring moisture-resistant thick film construction with standard temperature coefficient performance across industrial temperature ranges.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the allowable parameter tolerances for this resistor category.

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025J274CS is determined by strict adherence to the following criteria:

Mandatory Matching Parameters:

• Resistance value: 270 kOhms (exact match required)
• Package type: 2010 (5025 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match or better required)
• RoHS3 compliance (required)
• MSL 1 rating (required)

Allowable Variation Parameters:

• Tolerance: May be equal or tighter (±5% or better acceptable)
• Power rating: May be equal or higher (0.667W or greater acceptable)
• Manufacturer: Different manufacturers permitted if all other parameters match

The RC2010FK-07270KL from YAGEO qualifies as a substitute because it maintains identical resistance, package, composition, temperature coefficient, and operating range specifications while providing improved tolerance (±1% versus ±5%) and higher power rating (0.75W versus 0.667W).

Engineering Selection Recommendations

RC2010FK-07270KL (YAGEO) as Substitute:

The RC2010FK-07270KL is a direct substitute for the RC5025J274CS based on the following engineering criteria:

1. Electrical Equivalence: Both parts maintain identical 270 kOhms resistance value and ±100ppm/°C temperature coefficient across the full -55°C to 155°C operating range.

2. Mechanical Compatibility: Both components use identical 2010 (5025 Metric) package dimensions (5.00mm x 2.50mm), ensuring PCB footprint compatibility without layout modifications.

3. Performance Enhancement: The substitute provides tighter tolerance specification (±1% versus ±5%) and higher power dissipation capability (0.75W versus 0.667W), making it suitable for applications with more stringent accuracy or thermal requirements.

4. Regulatory Compliance: Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring equivalent environmental and handling requirements.

5. Product Availability: Both parts maintain Active product status with established manufacturing and supply chains.

Selection between these parts should be based on application-specific tolerance and power requirements rather than functional limitations.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-07270KL replace RC5025J274CS in existing designs without PCB modification?

A: Yes. Both parts use identical 2010 (5025 Metric) package dimensions (5.00mm x 2.50mm length and width). Seated height difference (0.66mm versus 0.65mm) is negligible for standard PCB assembly processes. No layout changes are required.

Q: What is the significance of the tolerance difference (±5% versus ±1%)?

A: The RC2010FK-07270KL provides tighter tolerance specification. In applications where 270 kOhms resistance accuracy is critical, the ±1% tolerance reduces component-level variation. For applications designed to the ±5% specification, both parts are functionally equivalent.

Q: Does the higher power rating (0.75W versus 0.667W) affect circuit performance?

A: No. Higher power rating indicates greater thermal dissipation capacity. If the original design requires 0.667W maximum dissipation, the 0.75W-rated substitute operates within safe margins with additional thermal headroom. This does not change electrical behavior.

Q: Are there packaging differences between these parts?

A: The RC5025J274CS is specified with standard packaging notation. The RC2010FK-07270KL is available in Tape & Reel (TR) format. Both use identical component geometry. Packaging format affects supply and handling procedures but not component performance or PCB compatibility.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity). Both maintain identical operating temperature range (-55°C to 155°C) and temperature coefficient (±100ppm/°C).

Q: Can RC5025J274CS be used as a substitute for RC2010FK-07270KL?

A: No. Substitution is directional based on parameter specifications. The RC5025J274CS has lower power rating (0.667W versus 0.75W) and wider tolerance (±5% versus ±1%). It does not meet the performance requirements of designs specified for the RC2010FK-07270KL.
