FCC16501ABTP Equivalent & Substitute Parts

Part Overview

The FCC16501ABTP is a surface mount chip fuse manufactured by Kamaya Inc., rated for 500 mA at 36 V DC with fast blow response characteristics. This component is designed for overcurrent protection in compact electronic assemblies utilizing 0603 (1608 Metric) package form factor. The part maintains active product status with full RoHS3 compliance and CSA/UL approval certifications. Substitute parts are identified to address inventory availability, extended voltage rating requirements, or alternative sourcing needs while maintaining functional equivalence within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FCC16501ABTP is determined by strict adherence to the following electrical and mechanical parameters:

Mandatory Match Criteria:

• Current Rating: 500 mA (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Response Time: Fast Blow (exact match required)
• Mounting Type: Surface Mount (exact match required)

Allowable Variation Criteria:

• Voltage Rating - DC: Substitute must equal or exceed 36 V
• Breaking Capacity @ Rated Voltage: Substitute must equal or exceed 35 A
• DC Cold Resistance: Substitute value acceptable if within normal manufacturing tolerance
• Operating Temperature Range: Substitute range may differ if it encompasses the application requirement
• Approval Agencies: Substitute must maintain equivalent safety certifications (UL, CSA)

The identified substitute SF-0603F050-2 satisfies all mandatory match criteria and exceeds allowable variation thresholds, providing enhanced voltage rating (50 V DC versus 36 V DC) and increased breaking capacity (50 A versus 35 A).

Engineering Selection Recommendations

FCC16501ABTP Selection Criteria:

• Applications requiring CSA certification in addition to UL approval
• Operating environments with extended low-temperature exposure below -20°C
• Systems where the narrower DC cold resistance specification (0.33 Ohms) is a design requirement
• Designs with voltage margins limited to 36 V DC maximum rating

SF-0603F050-2 Selection Criteria:

• Applications operating within -20°C to 105°C temperature range
• Designs benefiting from enhanced voltage rating margin (50 V DC)
• Systems requiring increased breaking capacity (50 A versus 35 A)
• Sourcing scenarios where Bourns Inc. component availability or lead times are advantageous
• Applications where UL certification alone satisfies regulatory requirements

Both parts maintain active product status, RoHS3 compliance, and REACH unaffected status. Selection between these components should be based on specific application voltage requirements, temperature operating range, and certification mandates rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Can SF-0603F050-2 be used as a direct replacement for FCC16501ABTP in all applications?

A: SF-0603F050-2 is functionally compatible for applications operating within its temperature range (-20°C to 105°C) and where UL certification satisfies regulatory requirements. Applications requiring CSA certification or operating below -20°C must use FCC16501ABTP.

Q: What is the significance of the voltage rating difference (36 V versus 50 V)?

A: The 50 V rating of SF-0603F050-2 provides additional voltage margin above the 36 V requirement of FCC16501ABTP. Both parts function identically in 36 V DC circuits. The higher rating does not affect protection characteristics or response time.

Q: Are the physical dimensions identical between these parts?

A: Both parts use the 0603 (1608 Metric) package with nearly identical dimensions. FCC16501ABTP measures 0.063" L x 0.031" W x 0.018" H; SF-0603F050-2 measures 0.063" L x 0.032" W x 0.018" H. The 0.001" width difference is within standard manufacturing tolerance and does not affect PCB footprint compatibility.

Q: How does the DC cold resistance difference impact circuit performance?

A: FCC16501ABTP exhibits 0.33 Ohms cold resistance while SF-0603F050-2 exhibits 0.25 Ohms. This 0.08 Ohm difference produces minimal voltage drop in typical 500 mA circuits (approximately 40 mV maximum). Selection should be based on application thermal budget and design specifications rather than this resistance variance.

Q: What approval agencies certify each part?

A: FCC16501ABTP carries CSA and UL approvals. SF-0603F050-2 carries UL approval. Applications requiring dual certification must specify FCC16501ABTP.

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

A: FCC16501ABTP operates to 125°C while SF-0603F050-2 operates to 105°C. Applications requiring operation above 105°C must use FCC16501ABTP. Applications within 105°C maximum temperature can use either part.

Q: What is the breaking capacity significance?

A: Breaking capacity indicates maximum fault current the fuse can safely interrupt. FCC16501ABTP breaks 35 A at rated voltage; SF-0603F050-2 breaks 50 A. Both values exceed typical circuit fault currents in 500 mA protected circuits. Selection based on breaking capacity is unnecessary for standard applications.
