FCC32102ADTP Equivalent & Substitute Parts

Part Overview

The FCC32102ADTP is a 1.0 A surface mount fuse rated for 64 V DC operation in a 1206 (3216 Metric) package form factor. Manufactured by Kamaya Inc., this fast-blow fuse is designed for board-level protection in electronic circuits requiring rapid response to overcurrent conditions. The component maintains Active product status with 986 units in current inventory stock.

Substitute parts are identified to address supply chain continuity, extended lead times, or specific application requirements where equivalent electrical and mechanical parameters are maintained within acceptable tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FCC32102ADTP is determined by alignment across the following critical parameters:

Electrical Parameters:

• Current Rating: 1 A (exact match required)
• Voltage Rating - DC: 64 V nominal (63 V minimum acceptable within standard tolerance)
• Breaking Capacity: 50 A (exact match)

Mechanical Parameters:

• Package / Case: 1206 (3216 Metric) (exact match required for PCB compatibility)
• Mounting Type: Surface Mount (exact match required)

Compliance Parameters:

• RoHS3 Compliant status (required for regulatory alignment)

The substitute part SF-1206S100-2 (Bourns Inc., SinglFuse™ SF-1206S series) meets these core substitution criteria. The 63 V DC rating operates within the acceptable voltage tolerance band relative to the 64 V specification. Both components share identical current rating, package form factor, surface mount configuration, and RoHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

FCC32102ADTP (Kamaya Inc.) is the primary component specification and should be selected when:

• Original design validation and certification are based on this specific part number
• Extended temperature operation below -20°C is required
• CSA or cUL certifications are mandatory for the application
• Current inventory availability supports project timelines

SF-1206S100-2 (Bourns Inc.) is an acceptable substitute when:

• Supply chain constraints limit FCC32102ADTP availability
• Operating temperature range of -20°C ~ 105°C satisfies application requirements
• UL certification meets regulatory compliance needs
• PCB layout and thermal management accommodate the slightly smaller physical dimensions (3.10mm L x 1.55mm W versus 3.20mm L x 1.60mm W)

Both components maintain ROHS3 compliance and equivalent DC cold resistance characteristics. The 1 V difference in DC voltage rating (63 V versus 64 V) falls within standard component tolerance bands for fuse specifications.

Frequently Asked Questions (FAQ)

Q: Can SF-1206S100-2 be used as a direct replacement for FCC32102ADTP in all applications?

A: SF-1206S100-2 is electrically and mechanically compatible for applications where the operating temperature range of -20°C ~ 105°C is acceptable. If the original design requires operation below -20°C or above 105°C, the FCC32102ADTP must be retained. Verify that UL certification satisfies your regulatory requirements if CSA or cUL certifications were originally specified.

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

A: The 63 V rating of SF-1206S100-2 versus the 64 V rating of FCC32102ADTP represents a 1.6% variance. This difference falls within standard tolerance bands for fuse component specifications and does not impact substitution eligibility for circuits operating at or below 63 V DC.

Q: Are there physical dimension differences between these parts?

A: Both components use the 1206 (3216 Metric) package form factor. Minor dimensional variations exist: FCC32102ADTP measures 3.20mm L x 1.60mm W x 0.60mm H, while SF-1206S100-2 measures 3.10mm L x 1.55mm W x 0.60mm H. These variations are within standard 1206 package tolerances and do not affect PCB footprint compatibility.

Q: What is the difference between Fast Blow and Slow Blow response characteristics?

A: FCC32102ADTP is specified as Fast Blow, responding rapidly to overcurrent conditions. SF-1206S100-2 is specified as Slow Blow, allowing brief current surges before activation. Application requirements determine which response characteristic is appropriate. Verify that the substitute part's response time aligns with circuit protection strategy before implementation.

Q: How do the approval agencies differ between these parts?

A: FCC32102ADTP carries CSA, cUL, and UL certifications. SF-1206S100-2 carries UL certification. If your application requires CSA or cUL approval specifically, the FCC32102ADTP must be used. If UL certification alone satisfies regulatory requirements, SF-1206S100-2 is acceptable.
