FCC32202ADTP Equivalent & Substitute Parts

Part Overview

The FCC32202ADTP is a 2.0 A fast-blow surface mount fuse rated for 64 V DC operation in a 1206 (3216 Metric) package. Manufactured by Kamaya Inc., this component is designed for board-level overcurrent protection in electronic assemblies. The part maintains active product status with 713 units in current inventory stock.

Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when design requirements necessitate equivalent functionality from alternative manufacturers. Substitutes must maintain electrical compatibility across current rating, voltage rating, package form factor, and mounting configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FCC32202ADTP are identified based on strict electrical and mechanical parameter alignment. The substitution criteria are:

Primary Matching Parameters:

• Current Rating: 2 A (exact match required)
• Voltage Rating - DC: 63 V or 64 V (within acceptable tolerance for DC fuse applications)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Breaking Capacity @ Rated Voltage: 50 A (exact match required)

Secondary Compliance Parameters:

• RoHS3 Compliance (required)
• REACH Unaffected status (required)
• Active product status (required)

The substitute part SF-1206S200-2 from Bourns Inc. meets all primary electrical parameters with a 63 V DC rating, which is within the acceptable range for DC fuse substitution. Both parts share identical current rating, package form factor, mounting configuration, and breaking capacity specifications.

Parameter Comparison

Engineering Selection Recommendations

FCC32202ADTP (Primary Part): The FCC32202ADTP is the specified component for applications requiring fast-blow response characteristics with extended operating temperature range (-55°C to 125°C). This part carries CSA, cUL, and UL approvals, providing broader certification coverage. The higher DC cold resistance (0.065 Ohms) may be relevant for circuits sensitive to fuse voltage drop. Select this part when fast-blow response is a circuit design requirement and extended temperature operation is necessary.

SF-1206S200-2 (Substitute Part): The SF-1206S200-2 serves as an alternative source for 2 A, 63 V DC fuse applications in 1206 surface mount packages. This part exhibits slow-blow response characteristics, which differs from the primary part. The lower DC cold resistance (0.032 Ohms) reduces voltage drop across the fuse element. Operating temperature range is limited to -20°C to 105°C. UL approval is provided. Select this part when slow-blow response is acceptable and operating temperature remains within the specified range.

Both parts maintain ROHS3 compliance and active product status, supporting long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can SF-1206S200-2 directly replace FCC32202ADTP in all applications?

A: Direct replacement is limited by response time differences. The FCC32202ADTP provides fast-blow response, while SF-1206S200-2 provides slow-blow response. Circuit designs that depend on fast-blow characteristics for protection timing will not function identically with the slow-blow substitute. Verify circuit protection requirements before substitution.

Q: What is the significance of the voltage rating difference (64 V vs. 63 V)?

A: Both ratings are within acceptable tolerance for DC fuse applications. The 63 V rating of SF-1206S200-2 is suitable for circuits operating at or below 63 V DC. For circuits operating above 63 V DC, the FCC32202ADTP with 64 V rating is required.

Q: Are both parts suitable for the same operating temperature range?

A: No. The FCC32202ADTP operates from -55°C to 125°C, while SF-1206S200-2 operates from -20°C to 105°C. Applications requiring operation below -20°C or above 105°C must use the FCC32202ADTP.

Q: Do both parts have identical package dimensions?

A: Both parts use the 1206 (3216 Metric) package form factor. Physical dimensions differ slightly: FCC32202ADTP measures 3.20mm x 1.60mm x 0.60mm, while SF-1206S200-2 measures 3.10mm x 1.55mm x 0.60mm. These differences are within standard 1206 package tolerances and do not affect PCB footprint compatibility.

Q: What approval agencies certify each part?

A: FCC32202ADTP carries CSA, cUL, and UL approvals. SF-1206S200-2 carries UL approval. Applications requiring CSA or cUL certification must use the FCC32202ADTP.

Q: How do the DC cold resistance values affect circuit performance?

A: DC cold resistance determines voltage drop across the fuse during normal operation. FCC32202ADTP exhibits 0.065 Ohms resistance, while SF-1206S200-2 exhibits 0.032 Ohms resistance. Circuits with tight voltage budgets or sensitive to fuse voltage drop should account for these differences during design verification.
