Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F181CS are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Parameters:

• Resistance value: 180 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 required)

Mechanical Parameters:

• Package format: 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)

Compliance Parameters:

• RoHS3 compliance (required)
• Moisture Sensitivity Level 1 (required)
• REACH unaffected status (required)

Allowable Variation:

• Power rating: Substitute parts may have equal or higher power ratings (0.75W / 3/4W acceptable for 0.667W / 2/3W applications)
• Packaging format: Original packaging (-) may be substituted with Tape & Reel (TR)
• Manufacturer: Different manufacturers acceptable if all electrical and mechanical parameters match

The identified substitute parts AC2010FK-07180RL and RC2010FK-07180RL meet all critical parameters with an upgrade in power rating from 0.667W to 0.75W, providing enhanced thermal margin without affecting circuit performance.

Engineering Selection Recommendations

RC5025F181CS (Samsung Electro-Mechanics)

Select this part for applications requiring the original Samsung manufacturer specification. The component is in active production with 1046 units in stock. ROHS3 compliance and MSL 1 rating support standard industrial and consumer applications without moisture sensitivity constraints.

AC2010FK-07180RL (YAGEO - Automotive Grade)

Select this part for automotive applications or systems requiring AEC-Q200 qualification. The automotive-grade certification provides enhanced reliability assurance for automotive-grade designs. The 0.75W power rating provides increased thermal margin compared to the original 0.667W specification. ROHS3 compliance and MSL 1 rating are maintained. Inventory availability is 12110 units.

RC2010FK-07180RL (YAGEO - Standard Grade)

Select this part for general-purpose applications where automotive certification is not required. The 0.75W power rating provides increased thermal margin. ROHS3 compliance and MSL 1 rating are maintained. Inventory availability is 1208 units. This part is suitable for direct substitution in non-automotive designs.

All three parts share identical electrical characteristics (180 Ohms ±1%, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range) and mechanical compatibility (2010 package, 5.00mm x 2.50mm dimensions). The primary differentiation factors are manufacturer, automotive certification availability, and power rating upgrade.

Frequently Asked Questions (FAQ)

Q: Can AC2010FK-07180RL or RC2010FK-07180RL be used as direct replacements for RC5025F181CS?

A: Yes. Both YAGEO parts are direct substitutes. All electrical parameters (resistance, tolerance, temperature coefficient, operating temperature range) are identical. The 2010 package format and physical dimensions are identical. The power rating upgrade from 0.667W to 0.75W does not affect compatibility; higher power ratings are acceptable in applications designed for lower power components.

Q: What is the difference between AC2010FK-07180RL and RC2010FK-07180RL?

A: The primary difference is automotive qualification. AC2010FK-07180RL carries AEC-Q200 automotive-grade certification, while RC2010FK-07180RL is standard industrial grade. Both have identical electrical specifications and 0.75W power ratings. Select AC2010FK-07180RL for automotive applications; select RC2010FK-07180RL for general industrial applications.

Q: Does the power rating upgrade from 0.667W to 0.75W affect circuit performance?

A: No. A higher power rating indicates the component can dissipate more power without exceeding temperature limits. In applications designed for 0.667W components, the 0.75W-rated substitutes operate within their specifications with additional thermal margin. No circuit redesign is required.

Q: Are the physical dimensions identical between all three parts?

A: Yes. All three parts use the 2010 (5025 Metric) package with dimensions of 0.197" L x 0.098" W (5.00mm x 2.50mm). Maximum seated heights are 0.026" (0.66mm for Samsung, 0.65mm for YAGEO parts). These minimal height differences do not affect PCB layout compatibility.

Q: What is the packaging difference between the original RC5025F181CS and the substitute parts?

A: The original RC5025F181CS is supplied in standard packaging (-). The substitute parts AC2010FK-07180RL and RC2010FK-07180RL are supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume manufacturing and automated assembly processes. Both packaging formats contain identical components.

Q: Are all three parts RoHS3 compliant?

A: Yes. RC5025F181CS, AC2010FK-07180RL, and RC2010FK-07180RL are all ROHS3 compliant and REACH unaffected. All parts meet current environmental and regulatory requirements for industrial and consumer applications.

Q: What does Moisture Sensitivity Level 1 mean?

A: MSL 1 indicates unlimited moisture sensitivity. These components do not require special moisture control during storage, handling, or assembly. Standard warehouse conditions and manufacturing processes are acceptable without desiccant packaging or controlled humidity environments.
