Substitute Part Grouping Explanation

Substitute parts for the RC5025F302CS are identified based on strict electrical and mechanical parameter matching. The substitution logic is governed by the following criteria:

Primary Matching Parameters:

• Resistance value: 3 kOhms (exact match required)
• Tolerance: ±1% (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 ~ 155°C (exact match required)
• Moisture resistance: Yes (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

Secondary Consideration:

• Power rating: The substitute part RC2010FK-073KL is rated at 0.75W (3/4W), which exceeds the original 0.667W (2/3W) specification. This represents an upgrade in thermal capacity and is acceptable for direct substitution in applications where the original power rating is sufficient, as the higher-rated component will not degrade performance.

The RC2010FK-073KL manufactured by YAGEO meets all primary matching parameters and provides equivalent electrical performance with enhanced power handling capability.

Parameter Comparison

Engineering Selection Recommendations

The RC2010FK-073KL from YAGEO is a direct substitute for the RC5025F302CS from Samsung Electro-Mechanics. Both components are Active product status with full regulatory compliance (RoHS3 Compliant, REACH Unaffected). The substitute part maintains identical electrical specifications including resistance value, tolerance, temperature coefficient, and operating temperature range. Physical dimensions and package footprint are equivalent, ensuring PCB layout compatibility without design modification.

The RC2010FK-073KL provides a power rating upgrade from 0.667W to 0.75W, which enhances thermal performance without introducing any electrical incompatibility. This upgrade is beneficial for applications operating near maximum power dissipation limits of the original specification.

Both components feature identical moisture resistance properties and unlimited MSL rating, making them suitable for standard manufacturing and storage conditions without special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-073KL replace RC5025F302CS in existing designs without PCB modification?

A: Yes. Both components share identical package dimensions (2010/5025 Metric), footprint, and termination configuration. No PCB layout changes are required for direct substitution.

Q: What is the significance of the power rating difference (0.667W vs 0.75W)?

A: The RC2010FK-073KL has a higher power dissipation rating. This represents a thermal capacity upgrade and does not create incompatibility. The substitute will operate safely in applications designed for the original 0.667W component.

Q: Are the electrical characteristics identical between these two parts?

A: Yes. Resistance value (3 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C) are identical across both components.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both RC5025F302CS and RC2010FK-073KL are RoHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the physical size compatibility status?

A: Both components are 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 compatible for standard PCB assembly processes.

Q: Are there any packaging format differences?

A: The RC5025F302CS is supplied in standard packaging, while RC2010FK-073KL is available in Tape & Reel (TR) format. Both formats are compatible with automated assembly equipment.
