FCC16801ADTP Equivalent & Substitute Parts

Part Overview

The FCC16801ADTP is an 800 mA surface mount fuse manufactured by Kamaya Inc., rated for 36 V DC operation in a 0603 (1608 Metric) package format. This component is designed for fast-blow response characteristics and is actively produced. Surface mount fuses of this specification are used in circuit protection applications where compact form factors and automated assembly are required. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory constraints necessitate component alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FCC16801ADTP are identified based on the following critical parameters that must align for functional equivalence:

Mandatory Matching Parameters:

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

Compatible Variation Parameters:

• Voltage Rating - DC: Substitute must equal or exceed 36 V
• Response Time: Fast Blow or Slow Blow acceptable based on circuit design requirements
• Operating Temperature Range: Substitute must cover the application's operating environment
• Breaking Capacity: Substitute must meet or exceed 35 A
• RoHS Compliance: ROHS3 Compliant status required

The substitute part SF-0603S080-2 from Bourns Inc. matches the mandatory parameters (800 mA, 0603 package, surface mount) and meets the voltage and compliance requirements, though with noted variations in response time and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (FCC16801ADTP): The FCC16801ADTP is the specified component and remains the preferred selection when available. It provides the exact voltage rating of 36 V DC, fast-blow response characteristics, and the widest operating temperature range (-55°C ~ 125°C). Dual approval by CSA and UL certifications supports broader regulatory acceptance.

Substitute Part (SF-0603S080-2): The SF-0603S080-2 from Bourns Inc. is electrically and mechanically compatible for applications where the following conditions are met:

1. Circuit maximum voltage does not exceed 32 V DC
2. Slow-blow response time is acceptable for the circuit protection scheme
3. Operating environment remains within -20°C ~ 105°C range
4. UL approval alone satisfies regulatory requirements

Both parts are actively produced, ROHS3 compliant, and carry unlimited moisture sensitivity level (MSL 1) ratings. The substitute part provides higher breaking capacity (50 A versus 35 A) and lower DC cold resistance (0.093 Ohms versus 0.2 Ohms), which are favorable characteristics for fault current interruption.

Frequently Asked Questions (FAQ)

Q: Can SF-0603S080-2 be used in place of FCC16801ADTP in all applications?

A: No. The SF-0603S080-2 has a lower DC voltage rating (32 V versus 36 V). Substitution is valid only when the circuit's maximum operating voltage does not exceed 32 V DC. Additionally, the response time differs (slow blow versus fast blow), which may affect circuit protection timing.

Q: What is the significance of the different response times (Fast Blow vs. Slow Blow)?

A: Fast-blow fuses interrupt circuits more rapidly upon overcurrent detection, providing faster protection against transient surges. Slow-blow fuses tolerate brief overcurrent conditions before interrupting, making them suitable for circuits with inrush currents. The choice depends on the specific circuit protection requirements and must be evaluated by the circuit designer.

Q: Are both parts physically identical in the 0603 package?

A: Both parts use the 0603 (1608 Metric) surface mount package and are mechanically compatible with the same PCB footprint. Dimensional variations are minimal (FCC16801ADTP: 0.063" L x 0.031" W x 0.018" H; SF-0603S080-2: 0.063" L x 0.032" W x 0.018" H), with only a 0.001" difference in width.

Q: Does the lower DC cold resistance of SF-0603S080-2 affect circuit performance?

A: The DC cold resistance difference (0.093 Ohms versus 0.2 Ohms) is minimal and produces negligible voltage drop across the fuse element under normal operating conditions. This variation does not impact circuit functionality in typical applications.

Q: What are the approval agency differences between these parts?

A: FCC16801ADTP carries dual approvals (CSA and UL), while SF-0603S080-2 carries UL approval only. If CSA certification is a regulatory requirement for the application, the primary part must be used.

Q: Can SF-0603S080-2 be used in applications requiring the full -55°C ~ 125°C temperature range?

A: No. SF-0603S080-2 is rated for -20°C ~ 105°C operation. Applications requiring operation below -20°C or above 105°C must use the FCC16801ADTP or identify an alternative part with the required temperature range.

Q: Are both parts RoHS compliant?

A: Yes. Both FCC16801ADTP and SF-0603S080-2 are ROHS3 compliant and carry unlimited moisture sensitivity level (MSL 1) ratings, making them suitable for standard PCB assembly processes without special handling requirements.
