BK/HTB-88 Cartridge Fuse Holder Equivalent & Substitute Parts

Part Overview

The BK/HTB-88 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 0.250" (6.3mm) spade terminals for single circuit protection.

The BK/HTB-88 carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing maintenance and production requirements for systems utilizing this fuse holder configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/HTB-88 is determined by strict equivalence across the following electrical and mechanical parameters:

• Current Rating: 20 A (exact match required)
• Voltage Rating: 250V (exact match required)
• Fuse Size: 0.25" Dia x 1.26" L / 6.35mm x 32mm (exact match required)
• Fuse Type: Cartridge (exact match required)
• Number of Circuits: 1 (exact match required)
• Mounting Type: Panel Mount (exact match required)
• Termination Style: Quick Connect - 0.250" (6.3mm) (exact match required)
• Compatible Fuse Standard: 3AG, 1/4" x 1-1/4" (SFE-20) (exact match required)

Substitute parts must satisfy all parameters listed above without deviation. The BK/HTB-88-R meets these criteria and is identified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The BK/HTB-88-R is a direct functional equivalent to the BK/HTB-88 and is suitable for substitution in applications requiring a 20 A, 250V single-circuit cartridge fuse holder with panel mount configuration and quick connect termination.

Product Status Consideration: The BK/HTB-88 is classified as obsolete, while the BK/HTB-88-R maintains active product status. Selection of the active substitute part ensures continued availability and supply chain support.

Compliance Consideration: The BK/HTB-88-R is RoHS compliant, whereas the main part is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the BK/HTB-88-R is the appropriate selection. Both parts share identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications.

Electrical and Mechanical Equivalence: All electrical parameters (current rating, voltage, fuse type, circuit count) and mechanical parameters (fuse size, mounting type, termination style) are identical between the two parts, confirming direct substitution capability.

Frequently Asked Questions (FAQ)

Q: Can the BK/HTB-88-R be used as a direct replacement for the BK/HTB-88?

A: Yes. The BK/HTB-88-R is electrically and mechanically equivalent to the BK/HTB-88. Both parts accommodate identical 20 A, 250V cartridge fuses (3AG, 1/4" x 1-1/4" standard), feature the same panel mount configuration, and utilize quick connect 0.250" (6.3mm) termination. All functional parameters are identical.

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

A: The BK/HTB-88 is obsolete, while the BK/HTB-88-R is an active product. Additionally, the BK/HTB-88-R is RoHS compliant, whereas the BK/HTB-88 is RoHS non-compliant. Functionally and electrically, the parts are equivalent.

Q: Are there packaging differences between the BK/HTB-88 and BK/HTB-88-R?

A: The BK/HTB-88-R is supplied in bulk packaging, whereas the main part packaging specification is not provided. Both parts are available in stock quantities (BK/HTB-88: 685 pcs; BK/HTB-88-R: 823 pcs).

Q: What fuse types are compatible with these fuse holders?

A: Both the BK/HTB-88 and BK/HTB-88-R are designed for 3AG cartridge fuses with dimensions 1/4" x 1-1/4" (6.35mm x 32mm), designated as SFE-20 standard.

Q: Are there any regulatory or compliance considerations when selecting between these parts?

A: If RoHS compliance is required for your application, the BK/HTB-88-R must be selected. Both parts carry identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.
