HBW-M-R Cartridge Fuse Holder Equivalent & Substitute Parts

Part Overview

The HBW-M-R is a cartridge fuse holder manufactured by Eaton - Electronics Division, designed for 5mm x 20mm fuses with a 16 A current rating at 250V. This through-hole mounted component is intended for single-circuit PCB applications requiring vertical orientation with PC pin termination. The product maintains Active status and is RoHS Compliant, making it suitable for modern electronic assembly requirements. Identifying equivalent substitute parts ensures design flexibility, supply chain continuity, and procurement optimization when the primary part number becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HBW-M-R are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Critical Parameters for Substitution:

• Current Rating: 16 A (exact match required)
• Voltage Rating: 250V (exact match required)
• Fuse Size: 5mm x 20mm (exact match required)
• Fuse Type: Cartridge (exact match required)
• Number of Circuits: 1 (exact match required)
• Mounting Type: Through Hole (exact match required)
• Orientation: Vertical (exact match required)
• Termination Style: PC Pin (exact match required)

Parts meeting all these parameters are classified as direct equivalents and may be substituted without circuit redesign or PCB layout modification.

Parameter Comparison

Engineering Selection Recommendations

The BK/HBW-M-R is a direct equivalent substitute for the HBW-M-R. Both parts are manufactured by Eaton - Electronics Division and share identical electrical specifications (16 A at 250V), mechanical dimensions (5mm x 20mm cartridge), and mounting characteristics (through-hole, vertical orientation, PC pin termination). Both parts maintain Active product status and RoHS Compliance certification, confirming their suitability for current manufacturing standards and regulatory requirements. The BK/HBW-M-R variant demonstrates equivalent reliability and environmental performance characteristics as indicated by matching Moisture Sensitivity Level ratings. Selection between these parts may be based on inventory availability, lead time, or procurement source preference, as no technical differentiation exists between them.

Frequently Asked Questions (FAQ)

Q: Can BK/HBW-M-R be used as a direct replacement for HBW-M-R without PCB modification?

A: Yes. Both parts are identical in electrical rating (16 A, 250V), fuse size (5mm x 20mm), mounting type (through-hole), orientation (vertical), and termination style (PC pin). No PCB layout or circuit redesign is required.

Q: Are there any compliance or certification differences between HBW-M-R and BK/HBW-M-R?

A: No. Both parts are RoHS Compliant with identical Moisture Sensitivity Level ratings (MSL 1 - Unlimited), confirming equivalent environmental and regulatory compliance.

Q: What fuse types are compatible with these holders?

A: These holders accept 5mm x 20mm cartridge fuses only. The fuse size and type are fixed design parameters and cannot be altered.

Q: Is the BK prefix in BK/HBW-M-R significant for substitution purposes?

A: The BK prefix is a manufacturer designation variant. It does not affect electrical performance, mechanical compatibility, or functional equivalence. Both part numbers reference the same fuse holder specification.

Q: Can these fuse holders be mounted horizontally instead of vertically?

A: No. These components are specified for vertical orientation only. Horizontal mounting would deviate from the qualified design and is not supported.

Q: What is the current inventory status for substitute parts?

A: HBW-M-R: 620 Pcs New Original In Stock. BK/HBW-M-R: 873 Pcs New Original In Stock. Inventory levels should be verified at time of procurement.
