BK/HTB-48M Fuse Holder Cartridge 250V 16A Panel Mount

Part Overview

The BK/HTB-48M is a cartridge fuse holder designed for 5mm x 20mm fuses with a 16 A current rating at 250V. This component is classified as obsolete and is intended for panel mount applications with quick connect termination. Due to its obsolete product status, equivalent substitute parts with active availability and improved compliance certifications are necessary for new designs and ongoing procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK/HTB-48M is based on electrical and mechanical parameter equivalence. The substitute part BK/HTB-48M-R maintains identical specifications across all critical parameters:

• Fuse size accommodation: 5mm x 20mm cartridge fuses
• Electrical ratings: 16 A at 250V
• Mechanical interface: Panel mount with quick connect 0.250" (6.3mm) termination
• Circuit configuration: Single circuit holder

The primary distinction between the main part and its substitute is product status and compliance certification. The BK/HTB-48M-R is classified as active and carries ROHS3 compliance, whereas the original part is obsolete and non-compliant with current RoHS standards.

Parameter Comparison

Engineering Selection Recommendations

The BK/HTB-48M-R is the direct substitute for the BK/HTB-48M. Selection of the substitute part is justified on the following grounds:

Product Status: The BK/HTB-48M is classified as obsolete, limiting long-term availability and supply chain reliability. The BK/HTB-48M-R maintains active product status, ensuring continued procurement capability.

Regulatory Compliance: The BK/HTB-48M-R is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The original part is RoHS non-compliant, which may restrict use in regulated markets and applications.

Electrical and Mechanical Equivalence: Both parts are identical in all functional parameters, including current rating, voltage rating, fuse size accommodation, mounting configuration, and termination style. Direct mechanical and electrical interchangeability is confirmed.

Inventory Availability: The BK/HTB-48M-R has higher inventory availability (1194 Pcs) compared to the original part (892 Pcs), supporting procurement continuity.

Frequently Asked Questions (FAQ)

Q: Can the BK/HTB-48M-R be used as a direct replacement for the BK/HTB-48M?

A: Yes. Both parts are electrically and mechanically equivalent. They accommodate identical 5mm x 20mm cartridge fuses, operate at 16 A and 250V, and use the same quick connect 0.250" (6.3mm) termination. Panel mount orientation and single-circuit configuration are identical.

Q: What is the primary difference between these two parts?

A: The BK/HTB-48M-R is an active product with ROHS3 compliance and REACH unaffected status, whereas the BK/HTB-48M is obsolete and RoHS non-compliant. Functionally, they are equivalent.

Q: Are there packaging differences between the BK/HTB-48M and BK/HTB-48M-R?

A: The BK/HTB-48M-R is supplied in bulk packaging, while the original part packaging specification is not provided in the available data.

Q: What fuse types are compatible with both holders?

A: Both holders are designed for 5mm x 20mm cartridge fuses with a 16 A current rating at 250V.

Q: Is the BK/HTB-48M-R suitable for new design implementations?

A: Yes. The active product status and current compliance certifications make the BK/HTB-48M-R appropriate for new designs requiring a 16 A, 250V single-circuit cartridge fuse holder with panel mount configuration.
