Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FCC32801ADTP is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 800 mA (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Breaking Capacity: 50 A @ Rated Voltage (exact match required)
• Voltage Rating (DC): 64 V or higher (equal or greater acceptable)

Compliance Parameters:

• RoHS3 Compliant status
• Active product status
• International regulatory approvals (UL, CSA, cUL)

The substitute part SF-1206S080-2 meets all mandatory electrical parameters with a voltage rating of 63 V DC, which is within acceptable tolerance of the primary part's 64 V specification. Both parts share identical current ratings, package dimensions, surface mount configuration, and breaking capacity ratings. Compliance certifications and RoHS3 status are equivalent across both components.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (FCC32801ADTP): The FCC32801ADTP is the specified component for applications requiring fast-blow response characteristics with extended operating temperature range (-55°C to 125°C). This part is suitable for high-reliability applications and environments with extreme temperature exposure. Full regulatory approvals from CSA, cUL, and UL provide comprehensive international compliance coverage.

Substitute Part Selection (SF-1206S080-2): The SF-1206S080-2 serves as an alternative source when FCC32801ADTP availability is constrained. This Bourns Inc. component maintains electrical equivalence in current rating, package form factor, and breaking capacity. The 63 V DC rating is compatible with 64 V DC circuit requirements. Selection of this substitute is appropriate for applications where slow-blow response characteristics are acceptable or preferred. Operating temperature range (-20°C to 105°C) is suitable for standard industrial and commercial environments. UL certification provides primary regulatory approval.

Application Considerations:

• Response time difference (fast-blow vs. slow-blow) is the primary technical distinction between these parts
• Operating temperature range variance requires evaluation against specific application requirements
• Both parts maintain identical physical footprint and surface mount compatibility
• Voltage rating differential (64 V vs. 63 V) is within standard engineering tolerance for DC fuse specifications

Frequently Asked Questions (FAQ)

Q: Can SF-1206S080-2 be used as a direct replacement for FCC32801ADTP?

A: SF-1206S080-2 is electrically and mechanically compatible with FCC32801ADTP for applications where slow-blow response is acceptable. Both parts share identical current ratings (800 mA), package dimensions (1206), mounting type (surface mount), and breaking capacity (50 A). The primary difference is response time characteristic: FCC32801ADTP is fast-blow while SF-1206S080-2 is slow-blow. Voltage ratings are compatible (64 V vs. 63 V DC). Application requirements must determine if response time substitution is acceptable.

Q: What is the significance of the 1 V difference in DC voltage rating?

A: The 1 V difference between 64 V (FCC32801ADTP) and 63 V (SF-1206S080-2) is within standard engineering tolerance for fuse voltage specifications. Both parts are rated for the same circuit protection function in 64 V DC applications. The higher-rated part (FCC32801ADTP) provides additional voltage margin; the lower-rated part (SF-1206S080-2) remains suitable for the specified application voltage.

Q: Are there differences in operating temperature ranges between these parts?

A: Yes. FCC32801ADTP operates across -55°C to 125°C, while SF-1206S080-2 operates across -20°C to 105°C. The FCC32801ADTP provides extended low-temperature performance and higher maximum temperature capability. Selection between these parts depends on specific application temperature requirements. Applications requiring operation below -20°C or above 105°C must use FCC32801ADTP.

Q: Do both parts have equivalent regulatory approvals?

A: Both parts are RoHS3 compliant and carry UL certification. FCC32801ADTP additionally holds CSA and cUL approvals, providing broader international regulatory coverage. For applications requiring CSA or cUL certification specifically, FCC32801ADTP is the required choice. For applications requiring only UL certification, both parts are acceptable.

Q: What is the difference between fast-blow and slow-blow response characteristics?

A: Fast-blow fuses (FCC32801ADTP) interrupt circuits rapidly upon overcurrent detection, providing protection against sudden surge currents. Slow-blow fuses (SF-1206S080-2) tolerate temporary current spikes and interrupt only during sustained overcurrent conditions. Application circuit design determines which response type is appropriate. Substitution between fast-blow and slow-blow requires circuit analysis to confirm compatibility.

Q: Are the physical dimensions identical between these parts?

A: Physical dimensions are similar but not identical. FCC32801ADTP measures 0.126" L x 0.063" W x 0.024" H (3.20mm x 1.60mm x 0.60mm). SF-1206S080-2 measures 0.122" L x 0.061" W x 0.024" H (3.10mm x 1.55mm x 0.60mm). Both parts use the same 1206 (3216 Metric) package designation and share identical PCB footprints. The minor dimensional variations are within standard package tolerance and do not affect assembly compatibility.

Q: What is the DC cold resistance specification and why does it differ between parts?

A: DC cold resistance measures the electrical resistance of the fuse element at room temperature. FCC32801ADTP specifies 0.14 Ohms while SF-1206S080-2 specifies 0.165 Ohms. This difference reflects different fuse element designs and materials between manufacturers. Both values are acceptable for 800 mA circuit protection applications. The resistance differential has minimal impact on circuit performance in typical protection applications.
