BK/HTC-35M Fuse Holder Cartridge 250V 10A Panel Mount - Equivalent & Substitute Parts

Part Overview

The BK/HTC-35M is a cartridge fuse holder manufactured by Eaton - Electronics Division, designed for panel mount applications with a 250V rating and 10A current capacity. This component accommodates 5mm x 20mm cartridge fuses in a single-circuit configuration with solder lug termination.

The BK/HTC-35M is classified as obsolete. Identification of equivalent and substitute parts is necessary to support ongoing maintenance, repair, and new design requirements where this model is no longer available through standard distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK/HTC-35M is determined by the following critical parameters that must remain compatible:

Mechanical Compatibility:

• Mounting type: Panel Mount
• Fuse size accommodation: 5mm x 20mm cartridge
• Number of circuits: 1

Electrical Compatibility:

• Voltage rating: 250V
• Fuse type: Cartridge

Functional Compatibility:

• Fuseholder type: Holder (passive component)

The BK/HTB-24M-R qualifies as a substitute based on these parameters. Both parts accommodate identical fuse dimensions (5mm x 20mm), share the same voltage rating (250V), support single-circuit operation, and are designed for panel mount installation. Both are classified as cartridge fuse holders.

The primary difference between these parts is the current rating: the BK/HTC-35M is rated for 10A, while the BK/HTB-24M-R is rated for 16A. The substitute part operates at a higher current capacity within the same voltage and mechanical envelope.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The BK/HTC-35M is obsolete and no longer supported by the manufacturer. The BK/HTB-24M-R is classified as active and maintains current manufacturing and distribution support.

Compliance and Certification: The BK/HTB-24M-R provides documented RoHS3 compliance and REACH unaffected status, offering regulatory assurance for applications subject to these requirements. The BK/HTC-35M does not provide these certifications in the available documentation.

Termination Compatibility: The main part features solder lug termination, while the substitute part uses Quick Connect - 0.187" (4.7mm) termination. Circuit board or wiring harness modifications may be required to accommodate this difference.

Current Rating Differential: The substitute part is rated for 16A compared to the main part's 10A rating. In applications where the circuit is designed for 10A operation, the higher-rated substitute part provides equivalent protection at the design current level and maintains compatibility with standard 5mm x 20mm fuses.

Frequently Asked Questions (FAQ)

Q: Can the BK/HTB-24M-R directly replace the BK/HTC-35M without modification?

A: Both parts accommodate identical 5mm x 20mm cartridge fuses and share the same 250V voltage rating and panel mount configuration. However, the termination style differs: the BK/HTC-35M uses solder lug termination while the BK/HTB-24M-R uses Quick Connect - 0.187" (4.7mm) termination. Circuit connection modifications are required.

Q: What is the significance of the current rating difference between 10A and 16A?

A: The BK/HTB-24M-R is rated for higher current capacity (16A) than the BK/HTC-35M (10A). Both parts function as passive holders for cartridge fuses. The actual circuit protection is determined by the fuse element installed in the holder, not the holder rating. The holder rating indicates the maximum current the holder contacts and internal structure can safely conduct.

Q: Are both parts suitable for the same fuse types?

A: Yes. Both the BK/HTC-35M and BK/HTB-24M-R are designed to accommodate 5mm x 20mm cartridge fuses. The fuse element selection determines the specific protection characteristics for a given circuit.

Q: What are the packaging differences?

A: The BK/HTC-35M is available in standard packaging (not specified). The BK/HTB-24M-R is supplied in bulk packaging.

Q: Does the BK/HTB-24M-R meet current regulatory requirements?

A: The BK/HTB-24M-R is documented as ROHS3 compliant and REACH unaffected. These certifications are not specified for the BK/HTC-35M in available documentation.
