BK/HTB-98I Cartridge Fuse Holder 250V 20A Panel Mount - Equivalent & Substitute Parts

Part Overview

The BK/HTB-98I 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, specifically compatible with 3AG and 1/4" x 1-1/4" (SFE-20) fuse types. The part features quick connect termination with 0.250" (6.3mm) spade terminals and supports a single circuit configuration.

The BK/HTB-98I 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 becomes limited.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK/HTB-98I is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Substitution 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 Standards: 3AG, 1/4" x 1-1/4" (SFE-20) (exact match required)

The substitute part BK/HTB-98I-R meets all critical electrical and mechanical parameters identically to the main part. The primary distinction is product status and RoHS compliance, which may influence selection based on application requirements and regulatory constraints.

Parameter Comparison

Engineering Selection Recommendations

BK/HTB-98I-R as Primary Substitute:

The BK/HTB-98I-R is a direct functional equivalent to the BK/HTB-98I across all electrical and mechanical parameters. Selection of BK/HTB-98I-R is supported by the following factors:

1. Product Status: BK/HTB-98I-R carries Active product status, ensuring ongoing manufacturer support, availability, and supply chain continuity compared to the Obsolete status of BK/HTB-98I.

2. RoHS Compliance: BK/HTB-98I-R is RoHS Compliant, meeting environmental and regulatory requirements mandated in many jurisdictions and by original equipment manufacturers. The BK/HTB-98I is RoHS non-compliant and may not satisfy current procurement or end-use requirements.

3. Electrical and Mechanical Equivalence: All critical parameters—current rating, voltage, fuse size, fuse type, circuit count, mounting configuration, and termination style—are identical between both parts.

4. Regulatory Classification: Both parts share identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications, indicating equivalent export control and tariff treatment.

For applications where RoHS compliance is mandatory or where long-term component availability is required, BK/HTB-98I-R is the appropriate selection. For legacy systems or applications where RoHS non-compliant components are explicitly permitted, BK/HTB-98I remains functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can BK/HTB-98I-R be used as a direct replacement for BK/HTB-98I in existing designs?

A: Yes. BK/HTB-98I-R is electrically and mechanically equivalent to BK/HTB-98I. Both parts accommodate identical fuse types (3AG, 1/4" x 1-1/4" / SFE-20), operate at 250V with 20 A current rating, feature identical panel mount configuration, and use the same quick connect 0.250" (6.3mm) termination. Physical dimensions and circuit count are identical.

Q: What is the primary difference between BK/HTB-98I and BK/HTB-98I-R?

A: The primary differences are product status and RoHS compliance. BK/HTB-98I is classified as Obsolete and RoHS non-compliant. BK/HTB-98I-R is Active and RoHS Compliant. All electrical and mechanical specifications are identical.

Q: Does RoHS compliance affect the functional performance of the fuse holder?

A: RoHS compliance relates to material composition and environmental restrictions on hazardous substances. It does not alter the electrical performance, current-carrying capacity, voltage rating, or mechanical fit of the fuse holder. Both parts function identically in circuit applications.

Q: Are there any packaging differences between BK/HTB-98I and BK/HTB-98I-R?

A: BK/HTB-98I-R is supplied in Bulk packaging. Packaging format does not affect component functionality or electrical characteristics.

Q: What fuse types are compatible with both BK/HTB-98I and BK/HTB-98I-R?

A: Both fuse holders accommodate 3AG and 1/4" x 1-1/4" (SFE-20) cartridge fuses with dimensions of 0.25" diameter by 1.26" length (6.35mm x 32mm).

Q: Can these fuse holders be used in applications rated above 250V?

A: No. Both BK/HTB-98I and BK/HTB-98I-R are rated for 250V maximum. Use in higher voltage applications exceeds the component specification and creates safety and reliability risks.

Q: Is BK/HTB-98I-R suitable for new product designs?

A: Yes. BK/HTB-98I-R carries Active product status and is RoHS Compliant, making it appropriate for new designs, particularly those subject to environmental regulations or requiring long-term component availability.
