FCC16102ADTP Equivalent & Substitute Parts

Part Overview

The FCC16102ADTP is a 1 A surface mount fuse rated for 36 V DC operation in a 0603 (1608 Metric) package form factor. Manufactured by Kamaya Inc., this component is designed for board-level overcurrent protection in compact electronic assemblies. The part maintains Active product status with full RoHS3 compliance and CSA/UL approval certifications.

Substitute parts are identified to address component availability, supply chain continuity, or specific application requirements while maintaining functional equivalence within defined electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FCC16102ADTP is determined by the following criteria:

Mandatory Matching Parameters:

• Current Rating: 1 A (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)

Minimum Acceptable Parameters:

• Voltage Rating - DC: Must be ≥ 36 V
• Operating Temperature Range: Must encompass or exceed -55°C ~ 125°C
• Approval Agency: Must include UL certification
• RoHS Status: Must be ROHS3 Compliant

The substitute part SF-0603S100-2 (Bourns Inc.) satisfies the mandatory matching parameters and maintains functional compatibility within the defined electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

FCC16102ADTP (Kamaya Inc.) is the primary component specification and remains the preferred selection for applications requiring:

• 36 V DC rated protection
• Extended operating temperature range (-55°C ~ 125°C)
• Dual certification (CSA and UL)
• Active product status with established supply

SF-0603S100-2 (Bourns Inc.) functions as an electrical and mechanical substitute where:

• Application voltage requirement does not exceed 32 V DC
• Operating temperature range requirement falls within -20°C ~ 105°C
• UL certification alone satisfies regulatory requirements
• Lower DC cold resistance (0.065 Ohms vs. 0.13 Ohms) is acceptable for the circuit design
• Higher breaking capacity (50 A vs. 35 A) provides additional margin

Both parts maintain Active product status, ROHS3 compliance, and identical 0603 package geometry. Selection between these components depends on specific circuit voltage and temperature operating conditions.

Frequently Asked Questions (FAQ)

Q: Can SF-0603S100-2 be used in an application designed for FCC16102ADTP?

A: Substitution is valid only if the application circuit operates at or below 32 V DC and within the -20°C ~ 105°C temperature range. The FCC16102ADTP is rated for 36 V DC and -55°C ~ 125°C; the substitute does not cover these extended parameters.

Q: Are the physical dimensions identical between these parts?

A: Both parts use the 0603 (1608 Metric) package with identical length (0.063" / 1.60 mm) and height (0.018" / 0.45 mm). Width differs slightly (0.031" vs. 0.032"), which does not affect PCB footprint compatibility.

Q: What is the significance of the DC cold resistance difference?

A: FCC16102ADTP has 0.13 Ohms cold resistance; SF-0603S100-2 has 0.065 Ohms. Lower resistance reduces voltage drop across the fuse during normal operation. This difference is circuit-dependent and must be evaluated against power dissipation and voltage regulation requirements.

Q: Does the substitute part have the same approval certifications?

A: FCC16102ADTP carries CSA and UL approvals. SF-0603S100-2 carries UL approval only. Applications requiring CSA certification must use the original part.

Q: What does "Slow Blow" response time mean for SF-0603S100-2?

A: Slow Blow indicates the fuse tolerates temporary current surges before opening. The FCC16102ADTP response time specification is not provided in the input data. Response time characteristics must be evaluated against specific circuit inrush current requirements.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes, both parts are surface mount 0603 packages with identical footprints. However, electrical parameter differences (voltage rating, temperature range, cold resistance) require circuit-level validation before substitution.

Q: What is the breaking capacity, and why does it differ between parts?

A: Breaking capacity is the maximum current the fuse can safely interrupt at rated voltage. FCC16102ADTP: 35 A at 36 V. SF-0603S100-2: 50 A at 32 V. Higher breaking capacity in the substitute provides additional safety margin but does not affect 1 A protection threshold operation.
