Key Parameters

Substitute Part Grouping Explanation

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

Electrical Parameters:

• Current Rating: 16 A (exact match required)
• Voltage Rating: 250V (exact match required)

Mechanical Parameters:

• Fuse Size: 5mm x 20mm (exact match required)
• Mounting Type: Through Hole (exact match required)
• Orientation: Vertical (exact match required)
• Termination Style: PC Pin (exact match required)
• Number of Circuits: 1 (exact match required)

The substitute part BK/HBW-M-R meets all electrical and mechanical parameters specified above, making it a direct functional equivalent for the obsolete BK/HBW-M.

Parameter Comparison

Engineering Selection Recommendations

The BK/HBW-M-R is the direct substitute for the obsolete BK/HBW-M. Both parts are manufactured by Eaton - Electronics Division and share identical electrical and mechanical specifications. The BK/HBW-M-R offers the additional advantage of active product status, ensuring continued availability and supply chain support. The BK/HBW-M-R is RoHS Compliant, whereas the original BK/HBW-M is RoHS non-compliant. For new designs or systems requiring regulatory compliance with RoHS standards, the BK/HBW-M-R is the appropriate selection. For legacy system maintenance where RoHS compliance is not a requirement, both parts are electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can the BK/HBW-M-R be used as a direct replacement for the BK/HBW-M?

A: Yes. The BK/HBW-M-R is a direct substitute. Both parts have identical current ratings (16 A), voltage ratings (250V), fuse sizes (5mm x 20mm), mounting types (Through Hole), orientations (Vertical), termination styles (PC Pin), and circuit configurations (1 circuit). No circuit modifications are required.

Q: What is the difference between the BK/HBW-M and BK/HBW-M-R?

A: The primary differences are product status and RoHS compliance. The BK/HBW-M is obsolete and RoHS non-compliant. The BK/HBW-M-R is active product status and RoHS Compliant. Electrical and mechanical specifications are identical.

Q: Why is the BK/HBW-M classified as obsolete?

A: The BK/HBW-M has been superseded by the BK/HBW-M-R. The BK/HBW-M-R provides the same functionality with improved compliance status and active manufacturer support.

Q: Are there any packaging differences between these parts?

A: The BK/HBW-M packaging is listed as unspecified. The BK/HBW-M-R is supplied in Bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: What fuse types are compatible with these holders?

A: Both the BK/HBW-M and BK/HBW-M-R accept 5mm x 20mm cartridge fuses rated for 16 A at 250V.

Q: Can these fuse holders be used in horizontal orientation?

A: No. Both parts are specified for vertical orientation only.
