Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BK/ABC-V-1-R are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Electrical Parameters (Must Match):

• Current Rating: 1 A (exact match required)
• Voltage Rating - AC: 250 V (minimum requirement)
• Voltage Rating - DC: 125 V (minimum requirement)
• Response Time: Fast Blow (circuit protection type must match)

Mechanical Parameters (Must Match):

• Fuse Type: Cartridge, Ceramic
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial)
• Mounting Type: Through Hole

Compliance Parameters (Must Match or Exceed):

• Approval Agencies: CSA and UL certifications required
• RoHS Status: ROHS3 Compliant

The substitute part 0324001.HXP from Littelfuse Inc. meets all critical electrical and mechanical requirements for direct substitution with the BK/ABC-V-1-R.

Parameter Comparison

Engineering Selection Recommendations

Both the BK/ABC-V-1-R and 0324001.HXP are active production components with full regulatory compliance. Selection between these parts should be based on the following factors:

BK/ABC-V-1-R (Eaton - Electronics Division):

• Holds CSA and UL certifications
• ROHS3 compliant
• Current inventory: 784 pieces

0324001.HXP (Littelfuse Inc.):

• Holds CE, CSA, PSE, and UL certifications (expanded regulatory coverage)
• ROHS3 compliant with REACH Unaffected status
• Current inventory: 1194 pieces
• Operating temperature range specified: -55°C ~ 125°C
• Moisture Sensitivity Level: 1 (Unlimited)

Both parts satisfy the electrical and mechanical requirements for direct substitution. The choice between manufacturers may be determined by supply chain considerations, inventory availability, or specific regional compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can 0324001.HXP be used as a direct replacement for BK/ABC-V-1-R?

A: Yes. Both parts share identical electrical ratings (1 A, 250 V AC, 125 V DC), fuse type (ceramic cartridge), response time (fast blow), and package specification (3AB, 3AG, 1/4" x 1-1/4" axial). Mechanical dimensions are within compatible tolerance. Both hold required CSA and UL certifications.

Q: Are there any dimensional differences between these parts?

A: Minor dimensional variations exist. BK/ABC-V-1-R measures 0.266" Dia x 1.292" L (6.76mm x 32.82mm), while 0324001.HXP measures 0.275" Dia x 1.288" L (6.99mm x 32.72mm). These differences are within acceptable tolerance for through-hole mounting applications using standard 3AB/3AG fuse holders.

Q: What is the difference in breaking capacity between these parts?

A: BK/ABC-V-1-R has a breaking capacity of 35 A AC and 10 kA DC. 0324001.HXP has a breaking capacity of 100 A AC and 10 kA DC. The higher AC breaking capacity of the Littelfuse part does not affect substitution compatibility and provides additional safety margin in AC applications.

Q: Do both parts have the same melting I²t value?

A: No. BK/ABC-V-1-R has a melting I²t of 0.431, while 0324001.HXP has a melting I²t of 0.69. Both parts maintain fast-blow response characteristics. The difference in I²t values reflects different internal fuse element designs but does not prevent substitution when both parts meet the circuit protection requirements.

Q: Are there compliance differences between these parts?

A: BK/ABC-V-1-R holds CSA and UL certifications. 0324001.HXP holds CE, CSA, PSE, and UL certifications. Both are ROHS3 compliant. The Littelfuse part provides expanded regulatory coverage for international applications.

Q: What is the DC cold resistance specification, and does it matter for substitution?

A: BK/ABC-V-1-R has a DC cold resistance of 0.195 Ohms, while 0324001.HXP has 0.189 Ohms. Both values are within acceptable range for ceramic cartridge fuses and do not affect substitution compatibility.
