BK/HTB-26 Cartridge Fuse Holder Equivalent & Substitute Parts

Part Overview

The BK/HTB-26 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 cartridge fuses (6.35mm x 32mm) and features quick connect termination with 0.250" (6.3mm) spade terminals for single circuit protection.

The BK/HTB-26 carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure procurement availability, and support ongoing system maintenance and repairs where original components are no longer in active production.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/HTB-26 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Current Rating: 20 A
• Voltage Rating: 250V
• Number of Circuits: 1

Mechanical Parameters:

• Fuse Size: 0.25" Dia x 1.26" L (6.35mm x 32mm)
• Mounting Type: Panel Mount
• Termination Style: Quick Connect - 0.250" (6.3mm)
• Fuse Type: Cartridge

Functional Parameters:

• Compatible Fuse Specification: 3AG, 1/4" x 1-1/4" (SFE-20)

The substitute part BK/HTB-26-R maintains identical electrical, mechanical, and functional specifications, ensuring direct interchangeability in applications originally designed for the BK/HTB-26.

Parameter Comparison

Engineering Selection Recommendations

BK/HTB-26-R is the direct substitute for BK/HTB-26. Selection between these parts is determined by regulatory and compliance requirements:

Use BK/HTB-26-R when:

• RoHS compliance is required for new designs or procurement
• Active product support and availability are priorities
• Current manufacturing standards must be met

Use BK/HTB-26 when:

• Legacy system maintenance requires exact original component matching
• RoHS non-compliance is acceptable for the application
• Existing inventory must be utilized

Both parts are classified under ECCN EAR99 and HTSUS 8538.90.8180, indicating identical export and tariff classification. The primary differentiation is product status (obsolete versus active) and RoHS compliance posture.

Frequently Asked Questions (FAQ)

Q: Can BK/HTB-26-R be used as a direct replacement for BK/HTB-26?

A: Yes. BK/HTB-26-R is electrically and mechanically identical to BK/HTB-26. All critical parameters—current rating (20 A), voltage rating (250V), fuse size (0.25" Dia x 1.26" L), mounting type (panel mount), and termination style (quick connect 0.250")—are equivalent. The parts are interchangeable in all applications.

Q: What is the difference between BK/HTB-26 and BK/HTB-26-R?

A: The primary differences are product status and regulatory compliance. BK/HTB-26 is obsolete and RoHS non-compliant. BK/HTB-26-R is active production and RoHS compliant. Functionally and electrically, they are identical.

Q: Are there packaging differences between these parts?

A: BK/HTB-26 packaging is listed as unspecified. BK/HTB-26-R is supplied in bulk packaging. Both parts are identical in form, fit, and function.

Q: What fuses are compatible with these holders?

A: Both BK/HTB-26 and BK/HTB-26-R accommodate 3AG cartridge fuses with dimensions 1/4" x 1-1/4" (SFE-20 specification), matching the 0.25" diameter by 1.26" length (6.35mm x 32mm) fuse cavity.

Q: Is RoHS compliance a functional requirement for my application?

A: RoHS compliance is a regulatory and procurement requirement, not a functional one. Both parts perform identically. Selection depends on whether your application, industry, or customer requirements mandate RoHS compliance.

Q: What is the current inventory status?

A: BK/HTB-26 has 1183 pieces in stock (obsolete status). BK/HTB-26-R has 782 pieces in stock (active status). For new procurement, BK/HTB-26-R is the recommended choice due to active production support.
