• Voltage Rating: 600 V AC minimum; 600 V DC minimum
• 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: Through-hole configuration
• Operating Temperature: -55°C ~ 125°C range
• Regulatory Compliance: cURus or UL approval

The substitute part BK-AHC-V-2-R, manufactured by Eaton - Electronics Division, meets all critical substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the 0ADAP2000-RE and BK-AHC-V-2-R maintain active product status and satisfy identical electrical and mechanical requirements for 2 A, 600 V AC/DC ceramic cartridge fuse applications. The 0ADAP2000-RE carries cURus certification, while the BK-AHC-V-2-R carries UL certification. Both certifications are recognized for industrial electrical safety compliance. Dimensional tolerances between the two parts (0.009" diameter variance and 0.004" length variance) remain within acceptable mechanical fit parameters for standard 3AB/3AG fuse holders. DC cold resistance values (0.155 Ω vs. 0.162 Ω) are functionally equivalent for circuit protection applications. Selection between these parts should be based on supply availability, lead time requirements, and existing certification documentation within the application's regulatory framework.

Frequently Asked Questions (FAQ)

Q: Can BK-AHC-V-2-R replace 0ADAP2000-RE in all applications?

A: Yes. Both parts share identical current ratings (2 A), voltage ratings (600 V AC/DC), response characteristics (fast blow), and breaking capacity (10 kA). Mechanical compatibility is confirmed through matching 3AB/3AG form factor and axial through-hole mounting. Dimensional differences are within standard fuse holder tolerances.

Q: Are there certification differences between these parts?

A: The 0ADAP2000-RE carries cURus approval, while BK-AHC-V-2-R carries UL approval. Both certifications meet industrial electrical safety standards. Application-specific regulatory requirements should determine which certification is required for your system.

Q: What is the significance of the DC cold resistance values?

A: DC cold resistance (0.155 Ω for 0ADAP2000-RE and 0.162 Ω for BK-AHC-V-2-R) represents the fuse element resistance at room temperature. The 0.007 Ω difference is negligible for overcurrent protection function and does not affect circuit performance in standard applications.

Q: Do dimensional differences affect mechanical fit?

A: Dimensional variations (0.009" diameter and 0.004" length) fall within standard mechanical tolerances for 3AB/3AG fuse holders. Both parts are mechanically compatible with standard fuse clips and holders designed for this form factor.

Q: What does the 10 kA breaking capacity specification mean?

A: Breaking capacity indicates the maximum fault current the fuse can safely interrupt at rated voltage without rupturing or creating hazardous conditions. Both parts are rated for 10 kA breaking capacity at 600 V, meeting industrial protection requirements.
