Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0ADAP4000-RE is determined by strict alignment with the following critical parameters:

• Current Rating: 4 A (exact match required)
• Voltage Rating: 600 V AC minimum; 600 V DC operation capability
• Fuse Type: Ceramic cartridge construction
• Response Time: Fast Blow characteristic
• Package / Case: 3AB, 3AG form factor with 1/4" x 1-1/4" (Axial) dimensions
• Breaking Capacity: 10 kA @ rated voltage
• Mounting Type: Through Hole
• Operating Temperature: -55°C ~ 125°C range compatibility

The substitute part BK-AHC-V-4-R meets all mandatory substitution criteria and is classified as a direct equivalent for the 0ADAP4000-RE.

Parameter Comparison

Engineering Selection Recommendations

Both the 0ADAP4000-RE and BK-AHC-V-4-R are active product status components with full regulatory compliance. The 0ADAP4000-RE carries cURus approval, while the BK-AHC-V-4-R carries UL approval. Both parts are ROHS3 compliant and meet the identical electrical and mechanical specifications for 4 A, 600 V AC/DC ceramic cartridge fuse applications.

The BK-AHC-V-4-R is a direct functional equivalent suitable for applications where the 0ADAP4000-RE is specified. Selection between these parts may be based on availability, lead time, or established supplier relationships, as both components satisfy the same electrical and mechanical requirements.

Frequently Asked Questions (FAQ)

Q: Can the BK-AHC-V-4-R be used as a direct replacement for the 0ADAP4000-RE?

A: Yes. Both parts are 4 A, 600 V AC/DC ceramic cartridge fuses with identical fast-blow response, 10 kA breaking capacity, and 3AB, 3AG package form factor. They are mechanically and electrically interchangeable for through-hole mounting applications.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. The 0ADAP4000-RE measures 0.266" diameter x 1.292" height, while the BK-AHC-V-4-R measures 0.275" diameter x 1.288" length. Both conform to the 3AB, 3AG standard package specification and are compatible with standard fuse holders designed for this form factor.

Q: What is the significance of the different Melting I²t values?

A: The Melting I²t parameter (15.5 for 0ADAP4000-RE and 9 for BK-AHC-V-4-R) reflects the thermal energy required to melt the fuse element. Both values are within acceptable ranges for 4 A fast-blow ceramic fuses and do not affect substitution eligibility for standard overcurrent protection applications.

Q: Do both parts meet the same regulatory standards?

A: Both parts are ROHS3 compliant. The 0ADAP4000-RE carries cURus approval, and the BK-AHC-V-4-R carries UL approval. Both certifications are recognized for industrial electrical component applications.

Q: What is the difference in DC Cold Resistance?

A: The 0ADAP4000-RE has 0.044 Ohms DC cold resistance, while the BK-AHC-V-4-R has 0.0538 Ohms. This minor difference does not affect substitution suitability for standard fuse applications.
