FCC16801ABTP Equivalent & Substitute Parts

Part Overview

The FCC16801ABTP is an 800 mA fast-blow surface mount fuse manufactured by Kamaya Inc. in the 0603 (1608 Metric) package. This component is rated for 36 V DC operation and is designed for board-level overcurrent protection in electronic assemblies. The part maintains Active product status with full RoHS3 compliance and international safety certifications (CSA, cUL, UL). Substitute parts are identified to address inventory availability, extended lead times, or specific application requirements while maintaining electrical and mechanical compatibility within defined parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FCC16801ABTP is determined by strict alignment of the following parameters:

Critical Electrical Parameters:

• Current Rating: 800 mA (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)

Voltage Rating Consideration: The FCC16801ABTP operates at 36 V DC. Substitute parts must maintain a voltage rating equal to or greater than 36 V DC to ensure safe operation within the original circuit design.

Compliance & Environmental:

• RoHS3 compliance required for regulatory alignment
• Moisture Sensitivity Level 1 (Unlimited) preferred for handling consistency
• Operating temperature range must accommodate application requirements

The identified substitute part SF-0603F080-2 (Bourns Inc., SinglFuse™ SF-0603F series) meets all critical electrical parameters and maintains equivalent package specifications. The substitute operates at 32 V DC, which is below the original 36 V rating; therefore, this part is suitable only for applications where the actual circuit voltage does not exceed 32 V DC.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (FCC16801ABTP): The FCC16801ABTP is the specified component and maintains full compatibility with designs rated for 36 V DC operation. This part carries Active product status with comprehensive international safety approvals (CSA, cUL, UL) and is available in stock (858 Pcs). Selection of the primary part is appropriate when the original design voltage specification of 36 V DC is required and inventory is available.

Substitute Part (SF-0603F080-2): The SF-0603F080-2 is a direct electrical substitute for applications where the circuit voltage does not exceed 32 V DC. This part is manufactured by Bourns Inc. under the SinglFuse™ SF-0603F series and maintains Active product status with UL approval. The substitute offers higher breaking capacity (50 A versus 35 A) and lower DC cold resistance (0.115 Ohms versus 0.2 Ohms), which may provide improved performance characteristics in low-voltage applications. Inventory availability is higher (2148 Pcs). The substitute is suitable for direct replacement only in circuits where the maximum operating voltage is confirmed to be 32 V DC or lower.

Temperature Consideration: The substitute part operates within a narrower temperature range (-20°C ~ 105°C) compared to the primary part (-55°C ~ 125°C). Applications requiring operation below -20°C or above 105°C must use the primary FCC16801ABTP component.

Frequently Asked Questions (FAQ)

Q: Can the SF-0603F080-2 be used as a direct replacement for the FCC16801ABTP in all applications?

A: No. The SF-0603F080-2 has a maximum voltage rating of 32 V DC, while the FCC16801ABTP is rated for 36 V DC. The substitute is suitable only for applications where the circuit voltage does not exceed 32 V DC. Verification of actual circuit voltage is required before substitution.

Q: Are the physical dimensions identical between the two parts?

A: The parts are functionally equivalent in physical dimensions. Both use the 0603 (1608 Metric) package. The width dimension differs slightly (0.031" versus 0.032"), which is within standard manufacturing tolerance and does not affect PCB layout compatibility.

Q: What is the significance of the lower DC cold resistance in the substitute part?

A: The SF-0603F080-2 exhibits lower DC cold resistance (0.115 Ohms versus 0.2 Ohms). This characteristic may result in reduced voltage drop across the fuse during normal operation, which can be beneficial in low-voltage applications but does not affect the fuse's protective function.

Q: Do both parts meet the same regulatory compliance standards?

A: Both parts are RoHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited). The primary part holds CSA, cUL, and UL approvals. The substitute part holds UL approval. Regulatory requirements specific to the application must be verified.

Q: What is the impact of the different operating temperature ranges?

A: The primary part operates from -55°C to 125°C, while the substitute operates from -20°C to 105°C. Applications requiring operation outside the substitute's temperature range must use the primary FCC16801ABTP component.

Q: Are both parts available in the same packaging format?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging, which is standard for surface mount assembly processes.

Q: What does "Fast Blow" response time mean?

A: Fast Blow indicates that the fuse responds quickly to overcurrent conditions, providing rapid circuit protection. Both the primary and substitute parts share this characteristic, ensuring equivalent protective response.
