Key Parameters

Substitute Part Grouping Explanation

The Bel Fuse Inc. 0ADKP6300-RE qualifies as a substitute based on the following alignment criteria:

Current Rating: Both parts are rated at 6.3 A, providing identical overcurrent protection thresholds.

Package Dimensions: Both utilize the 5mm x 20mm axial through-hole configuration, ensuring mechanical and electrical compatibility in existing PCB layouts.

Response Time: Both employ slow-blow characteristics, maintaining consistent circuit protection behavior during transient current conditions.

Fuse Type: Both are ceramic cartridge fuses, ensuring equivalent thermal and electrical performance.

Operating Temperature: Both support the -55°C ~ 125°C range, confirming thermal compatibility across industrial and commercial applications.

Voltage Ratings: The substitute part exceeds the original voltage specifications (600 V AC / 500 V DC versus 500 V AC / 450 V DC), permitting use in applications rated at or below the original part's voltage limits.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain active product status and comply with RoHS3 requirements. The Littelfuse 097706.3MXEP carries CE, PSE, and SEMKO certifications, while the Bel Fuse 0ADKP6300-RE holds cURus certification. Selection between these parts depends on regional compliance requirements and certification acceptance within the target application. The Bel Fuse substitute provides higher breaking capacity ratings and elevated voltage specifications, making it suitable for applications requiring enhanced performance margins within the same current and package envelope.

Frequently Asked Questions (FAQ)

Can the Bel Fuse 0ADKP6300-RE replace the Littelfuse 097706.3MXEP in all applications?

Yes, within applications rated at or below the original part's voltage specifications (500 V AC / 450 V DC). The substitute's higher voltage ratings (600 V AC / 500 V DC) do not restrict its use in lower-voltage circuits. Current rating, package dimensions, and response time are identical, ensuring direct functional replacement.

Are the physical dimensions identical between these parts?

Both parts use the 5mm x 20mm axial through-hole package. The Littelfuse part measures 0.228" diameter x 0.886" length, while the Bel Fuse part measures 0.236" diameter x 0.886" length. The minor diameter difference does not affect PCB mounting compatibility for standard fuse holders.

What is the difference in breaking capacity between these parts?

The Littelfuse 097706.3MXEP has a breaking capacity of 100A AC and 200A DC at rated voltage. The Bel Fuse 0ADKP6300-RE provides 200A AC and 300A DC breaking capacity. Higher breaking capacity indicates enhanced fault current handling capability without affecting normal operation.

Do both parts support the same operating temperature range?

Yes, both parts operate across -55°C to 125°C, ensuring thermal compatibility in equivalent environmental conditions.

Which certifications apply to each part?

The Littelfuse 097706.3MXEP carries CE, PSE, and SEMKO approvals. The Bel Fuse 0ADKP6300-RE holds cURus certification. Verify that the required certification for your application is present before selection.
