BK/HTB-94I Cartridge Fuse Holder 250V 20A Panel Mount

Part Overview

The BK/HTB-94I is a cartridge fuse holder manufactured by Eaton - Electronics Division, designed for panel mount applications with a 20 A current rating at 250V. This component accommodates 0.25" diameter by 1.26" length (6.35mm x 32mm) cartridge fuses and features quick connect termination with 0.187" (4.7mm) spade terminals.

The BK/HTB-94I is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing maintenance, repair, and new design requirements where this fuse holder specification is required but original stock availability is limited.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK/HTB-94I is determined by strict equivalence across the following electrical and mechanical parameters:

• Current Rating: 20 A
• Voltage Rating: 250V
• Fuse Size: 0.25" Dia x 1.26" L (6.35mm x 32mm)
• Fuse Type: Cartridge
• Number of Circuits: 1
• Mounting Type: Panel Mount
• Termination Style: Quick Connect - 0.187" (4.7mm)
• Compatible Fuse Type: 3AG, 1/4" x 1-1/4" (SFE-20)

All substitute parts must maintain identical electrical ratings, mechanical dimensions, and interface specifications to ensure direct functional replacement without circuit modification or mechanical rework.

Parameter Comparison

Engineering Selection Recommendations

The BK/HTB-94I-R is a direct functional equivalent to the BK/HTB-94I. Both components share identical electrical ratings (20 A, 250V), mechanical dimensions (0.25" Dia x 1.26" L), fuse type (Cartridge), mounting configuration (Panel Mount), and termination interface (Quick Connect - 0.187").

The primary distinction between these parts is product status and regulatory compliance. The BK/HTB-94I is classified as obsolete, while the BK/HTB-94I-R maintains active product status. Additionally, the BK/HTB-94I-R is RoHS Compliant, whereas the BK/HTB-94I is RoHS non-compliant.

For new designs or applications requiring current regulatory compliance, the BK/HTB-94I-R is the appropriate selection. For legacy system maintenance where the original BK/HTB-94I specification must be preserved, the BK/HTB-94I-R provides electrical and mechanical compatibility without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the BK/HTB-94I-R be used as a direct replacement for the BK/HTB-94I?

A: Yes. Both components are manufactured by Eaton - Electronics Division within the HTB series and maintain identical electrical ratings (20 A, 250V), mechanical dimensions (0.25" Dia x 1.26" L), fuse type (Cartridge), mounting type (Panel Mount), and termination style (Quick Connect - 0.187"). No circuit modification or mechanical rework is required.

Q: What is the difference between the BK/HTB-94I and BK/HTB-94I-R?
