BK/HTB-82I Cartridge Fuse Holder 250V 20A Panel Mount

Part Overview

The BK/HTB-82I 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, featuring a single circuit configuration with quick connect termination. The part is currently active in production status. Substitute parts are identified when packaging format differs, compliance certifications change, or inventory availability requires alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The BK/HTB-82I-R is classified as a direct substitute based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Current rating: 20 A (identical)
• Voltage rating: 250V (identical)
• Fuse size: 0.25" Dia x 1.26" L / 6.35mm x 32mm (identical)
• Fuse type: Cartridge 3AG (identical)
• Number of circuits: 1 (identical)
• Mounting type: Panel Mount (identical)
• Termination style: Quick Connect - 0.187" (4.7mm) (identical)

The primary difference between the main part and substitute is packaging format (Bulk versus Box) and RoHS compliance status. Both parts are manufactured by Eaton - Electronics Division within the HTB series and maintain full functional and dimensional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both BK/HTB-82I and BK/HTB-82I-R are active production parts from Eaton - Electronics Division with identical electrical and mechanical specifications. Selection between these parts is determined by compliance requirements and packaging needs:

BK/HTB-82I (Bulk Packaging): Select this part number when RoHS non-compliant components are acceptable for the application and bulk packaging is preferred for high-volume procurement.

BK/HTB-82I-R (Box Packaging): Select this part number when ROHS3 compliance is required by design specifications, regulatory requirements, or customer mandates. This variant is also suitable when box packaging is required for inventory management or distribution purposes.

Both parts maintain identical current rating (20 A), voltage rating (250V), fuse accommodation (3AG cartridge, 0.25" Dia x 1.26" L), mounting configuration (panel mount), and termination style (quick connect 0.187"). Functional interchangeability is complete across all electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can BK/HTB-82I and BK/HTB-82I-R be used interchangeably in the same circuit?

A: Yes. Both parts are electrically and mechanically identical. They accommodate the same 20 A, 250V cartridge fuses, feature identical panel mount configuration, and use the same quick connect termination. Substitution is valid from a functional standpoint.

Q: What is the difference between BK/HTB-82I and BK/HTB-82I-R?

A: The primary differences are packaging format and RoHS compliance status. BK/HTB-82I is supplied in bulk packaging and is RoHS non-compliant. BK/HTB-82I-R is supplied in box packaging and is ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Which part should I select if my application requires RoHS compliance?

A: Select BK/HTB-82I-R, which carries ROHS3 compliance certification. The BK/HTB-82I is RoHS non-compliant and should not be used in applications with RoHS requirements.

Q: Are the fuse cartridges compatible between both part numbers?

A: Yes. Both BK/HTB-82I and BK/HTB-82I-R accommodate 3AG cartridge fuses with dimensions 0.25" Dia x 1.26" L (6.35mm x 32mm) and ratings of 20 A at 250V. Fuse compatibility is identical.

Q: What is the termination type for these fuse holders?

A: Both parts feature quick connect termination with 0.187" (4.7mm) spade connectors, enabling direct connection to standard panel-mount circuit configurations.

Q: Is there a difference in moisture sensitivity between the two parts?

A: No. Both BK/HTB-82I and BK/HTB-82I-R have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
