Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F331CS is determined by strict adherence to the following criteria:

Mandatory Matching Parameters:

• Resistance value: 330 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Package format: 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 (substitute must support full range)
• Moisture Resistance: Required feature
• RoHS3 Compliance: Required
• MSL Rating: 1 (Unlimited) (substitute must equal or exceed)

Allowable Variation Parameters:

• Power Rating: Substitute must equal or exceed 0.667W; higher ratings are acceptable
• Packaging Format: Tape & Reel acceptable as alternative to standard packaging

The identified substitutes AC2010FK-07330RL and RC2010FK-07330RL meet all mandatory criteria while offering increased power ratings of 0.75W (3/4W), providing enhanced thermal margin in applications.

Parameter Comparison

Engineering Selection Recommendations

RC5025F331CS (Samsung Electro-Mechanics) - Primary Part

Use the original Samsung part when inventory is available and application requirements do not demand automotive-grade certification. This part maintains Active product status with established supply chain presence.

AC2010FK-07330RL (YAGEO) - Automotive-Grade Substitute

Select this substitute when automotive AEC-Q200 certification is required or when enhanced thermal performance is needed. The increased power rating of 0.75W provides additional safety margin. This part is suitable for automotive and industrial applications requiring higher reliability standards. Inventory availability is 8665 units.

RC2010FK-07330RL (YAGEO) - Standard Substitute

Use this substitute for general industrial applications requiring increased power rating without automotive certification requirements. The 0.75W rating provides thermal margin improvement over the original specification. Inventory availability is 6938 units. Both YAGEO substitutes maintain full RoHS3 compliance and MSL 1 rating.

All three parts are electrically and mechanically interchangeable within the specified parameters. Selection should be based on application requirements, certification needs, and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can AC2010FK-07330RL and RC2010FK-07330RL be used interchangeably with RC5025F331CS?

A: Yes. Both YAGEO parts meet all mandatory electrical and mechanical parameters. The primary difference is that AC2010FK-07330RL includes AEC-Q200 automotive certification, while RC2010FK-07330RL does not. Both offer increased power rating (0.75W vs. 0.667W), which is an allowable variation that improves thermal performance.

Q: Does the increased power rating of 0.75W affect circuit operation?

A: No. The power rating specifies maximum continuous power dissipation capability. A higher rating does not change electrical behavior in the circuit. The component will operate identically to the original part at equivalent power levels.

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

A: Yes. All three parts use the 2010 (5025 Metric) package with identical length and width (0.197" L x 0.098" W / 5.00mm x 2.50mm). Maximum seated height is 0.026" (0.66mm for Samsung, 0.65mm for YAGEO), which is negligible for PCB assembly compatibility.

Q: What is the significance of Tape & Reel packaging for the YAGEO substitutes?

A: Tape & Reel (TR) packaging is standard for automated PCB assembly processes. This format is compatible with pick-and-place equipment and does not affect component performance or compatibility. The original Samsung part uses standard packaging; both formats are functionally equivalent for circuit operation.

Q: Why does AC2010FK-07330RL have AEC-Q200 certification while RC2010FK-07330RL does not?

A: AEC-Q200 is an automotive industry qualification standard. AC2010FK-07330RL is specifically qualified for automotive applications, while RC2010FK-07330RL is a general industrial-grade part. Both meet identical electrical specifications; the certification difference reflects intended application markets.

Q: Are all three parts RoHS3 compliant?

A: Yes. RC5025F331CS, AC2010FK-07330RL, and RC2010FK-07330RL are all ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating, ensuring compliance with environmental and reliability standards.

Q: Can these parts be used in high-temperature applications?

A: Yes. All three parts support the full operating temperature range of -55°C ~ 155°C with ±100ppm/°C temperature coefficient, making them suitable for industrial and automotive environments with extended temperature requirements.
