BK/HTB-88I Cartridge Fuse Holder 250V 20A Panel Mount - Equivalent & Substitute Parts

Part Overview

The BK/HTB-88I is a cartridge fuse holder manufactured by Eaton - Electronics Division, designed for panel mount applications. This component accommodates 3AG cartridge fuses rated at 20 amperes and 250 volts, with a single circuit configuration. The fuse holder features quick connect termination (0.250" / 6.3mm) and accepts fuses measuring 0.25" diameter by 1.26" length (6.35mm x 32mm). The product maintains Active status in the manufacturer's portfolio. Substitute components are identified to address inventory availability, compliance requirements, or specific application needs while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK/HTB-88I is based on strict equivalence of the following critical parameters:

Electrical Compatibility Parameters:

• Current Rating: 20 A (exact match required)
• Voltage Rating: 250V (exact match required)
• Number of Circuits: 1 (exact match required)

Mechanical Compatibility Parameters:

• Fuse Size: 0.25" Dia x 1.26" L / 6.35mm x 32mm (exact match required)
• Fuse Type: Cartridge (3AG standard)
• Mounting Type: Panel Mount (exact match required)
• Termination Style: Quick Connect - 0.250" (6.3mm) (exact match required)

Compliance Parameters:

• Series: HTB (manufacturer series designation)
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitute part BK/HTB-88I-R maintains identical electrical and mechanical specifications. The primary distinction between the main part and its substitute relates to RoHS compliance status, which does not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

BK/HTB-88I (Original Part):

• Active product status with established supply chain
• RoHS non-compliant designation
• Current inventory: 1047 pieces
• Suitable for applications where RoHS compliance is not a regulatory requirement

BK/HTB-88I-R (Substitute Part):

• Active product status with established supply chain
• RoHS Compliant designation
• Current inventory: 935 pieces
• Suitable for applications requiring RoHS compliance or where regulatory standards mandate lead-free construction
• Electrically and mechanically interchangeable with BK/HTB-88I

Selection between these parts is determined by compliance requirements specific to the end application or regional regulations. Both parts are functionally equivalent for circuit protection applications requiring 20A, 250V cartridge fuse holders with panel mount configuration.

Frequently Asked Questions (FAQ)

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

A: Yes. The BK/HTB-88I-R is electrically and mechanically interchangeable with BK/HTB-88I. All critical parameters including current rating (20A), voltage rating (250V), fuse size (0.25" x 1.26"), mounting type (panel mount), and termination style (quick connect 0.250") are identical. The primary difference is RoHS compliance status.

Q: What fuse types are compatible with these holders?

A: Both BK/HTB-88I and BK/HTB-88I-R accept 3AG cartridge fuses with dimensions 1/4" x 1-1/4" (0.25" diameter x 1.26" length / 6.35mm x 32mm). Fuses must be rated for 20A at 250V maximum.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical or mechanical performance. Both the RoHS non-compliant BK/HTB-88I and RoHS Compliant BK/HTB-88I-R deliver identical electrical characteristics and mechanical function.

Q: Are these holders suitable for panel mount applications?

A: Yes. Both BK/HTB-88I and BK/HTB-88I-R are specifically designed for panel mount installation. The quick connect termination (0.250" / 6.3mm) provides standard connection methodology for panel-mounted fuse holder applications.

Q: What is the moisture sensitivity level for these components?

A: Both parts carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements during storage or handling.

Q: How do I determine which part to order?

A: If your application or regional regulations require RoHS compliance, select BK/HTB-88I-R. If RoHS compliance is not a requirement, either part is acceptable. Verify current inventory availability through your supplier, as stock levels may vary.
