Substitute Part Grouping Explanation

Substitution of the 0ADAP1000-RE is determined by strict equivalence across the following critical parameters:

• Current Rating: 1 A (exact match required)
• Voltage Rating: 600 V AC and 600 V DC (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial) (exact match required)
• Breaking Capacity: 10 kA (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

The BK-AHC-V-1-R manufactured by Eaton - Electronics Division meets all critical electrical and mechanical parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the 0ADAP1000-RE and BK-AHC-V-1-R are active production components with ROHS3 compliance. The 0ADAP1000-RE carries cURus approval, while the BK-AHC-V-1-R carries UL approval. Both certifications are recognized standards for electrical safety. Selection between these parts should be based on:

• Approval agency requirements specified in the application or end-use equipment certification
• Inventory availability and lead time considerations
• Existing supply chain relationships with manufacturers

The minor differences in melting I²t (0.23 vs. 0.3) and DC cold resistance (0.45 Ohms vs. 0.36 Ohms) do not affect functional equivalence for standard circuit protection applications within the specified electrical ratings.

Frequently Asked Questions (FAQ)

Q: Can the BK-AHC-V-1-R replace the 0ADAP1000-RE in existing designs?

A: Yes. Both parts are 1 A, 600 V AC/DC ceramic cartridge fuses with identical package dimensions (3AB, 3AG, 1/4" x 1-1/4"), fast-blow response, and 10 kA breaking capacity. Through-hole mounting is identical.

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

A: The melting I²t values (0.23 vs. 0.3) represent the thermal energy required to melt the fuse element. Both values fall within the acceptable range for 1 A fast-blow ceramic fuses and do not affect substitution eligibility for standard applications.

Q: Are there differences in approval certifications?

A: The 0ADAP1000-RE carries cURus approval, while the BK-AHC-V-1-R carries UL approval. Both are recognized safety certifications. Equipment certification requirements should determine which approval is necessary for your application.

Q: Do the physical dimensions differ between these parts?

A: Dimensions are functionally equivalent. The 0ADAP1000-RE measures 0.266" Dia x 1.292" H, while the BK-AHC-V-1-R measures 0.275" Dia x 1.288" L. Both conform to the 3AB, 3AG, 1/4" x 1-1/4" standard package specification and are mechanically interchangeable in through-hole applications.

Q: What does the DC cold resistance difference mean for circuit performance?

A: DC cold resistance (0.45 Ohms vs. 0.36 Ohms) has minimal impact on circuit operation under normal conditions. Both values are within acceptable limits for ceramic cartridge fuses in this current rating and do not affect substitution compatibility.
