0ADAP0400-RE Equivalent & Substitute Parts

Part Overview

The 0ADAP0400-RE is a 400 mA ceramic cartridge fuse rated for 600 V AC/DC operation, manufactured by Bel Fuse Inc. This fast-blow fuse is designed for through-hole mounting in axial configuration (3AB, 3AG package) and is suitable for electrical and industrial applications requiring overcurrent protection. The part maintains active product status with cURus approval certification and full RoHS3 compliance. Substitute parts are identified to provide alternative sourcing options when primary inventory is unavailable or when supply chain diversification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0ADAP0400-RE is determined by strict equivalence across the following critical parameters:

• Current Rating: 400 mA (exact match required)
• Voltage Rating: 600 V AC and 600 V DC (both must be met)
• Fuse Type: Cartridge, Ceramic (mechanical and electrical characteristics)
• Response Time: Fast Blow (protection curve classification)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" Axial (physical and electrical interface)
• Mounting Type: Through Hole (circuit board integration)
• Breaking Capacity: 10 kA @ Rated Voltage (fault interruption capability)
• Approval Agency: cURus certification (regulatory compliance)

The substitute part BK-AHC-V-400-R, manufactured by Eaton - Electronics Division, meets all specified parameters and qualifies as a direct equivalent for the 0ADAP0400-RE.

Parameter Comparison

Engineering Selection Recommendations

Both the 0ADAP0400-RE and BK-AHC-V-400-R maintain active product status and carry cURus approval certification, confirming regulatory compliance for industrial and electrical applications. Both parts are ROHS3 compliant and operate across the identical temperature range of -55°C to 125°C. The electrical and mechanical specifications are equivalent, including current rating, voltage ratings, breaking capacity, and physical dimensions. Selection between these parts may be based on inventory availability, supply chain preferences, or organizational procurement policies. The DC cold resistance differential (1.875 Ohms versus 1.436 Ohms) represents a minor variation within acceptable engineering tolerances for this fuse category and does not affect functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can BK-AHC-V-400-R be used as a direct replacement for 0ADAP0400-RE?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical current ratings (400 mA), voltage ratings (600 V AC/DC), fuse type (ceramic cartridge), response time (fast blow), package configuration (3AB, 3AG axial), and breaking capacity (10 kA). Both carry cURus certification and ROHS3 compliance.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.266" diameter by 1.292" length (6.76mm x 32.82mm), ensuring identical through-hole mounting compatibility.

Q: Does the difference in DC cold resistance affect substitution eligibility?

A: No. The DC cold resistance values (1.875 Ohms for 0ADAP0400-RE and 1.436 Ohms for BK-AHC-V-400-R) fall within acceptable engineering tolerances for ceramic cartridge fuses in this current and voltage class and do not impact functional equivalence or circuit performance.

Q: Are both parts certified for the same applications?

A: Yes. Both parts carry cURus approval and are rated for electrical and industrial applications requiring 600 V AC/DC overcurrent protection at 400 mA.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -55°C to 125°C, providing identical thermal performance specifications.
