Equivalent & Substitute Parts for BK/HTC-210M Fuse Clip Cartridge

Part Overview

The BK/HTC-210M is a cartridge fuse clip manufactured by Eaton - Electronics Division, rated for 6.3 A at 250V with through-hole PCB mounting. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement requirements. The part accommodates 5mm diameter cartridge fuses in a single-circuit horizontal orientation with tin-plated brass contacts and PC pin termination.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/HTC-210M is determined by the following critical parameters:

Primary Compatibility Criteria:

• Fuse size: 5mm diameter cartridge format
• Mounting method: Through-hole PCB mounting
• Termination: PC pin configuration
• Circuit count: Single circuit
• Orientation: Horizontal mounting

Voltage and Current Considerations: Substitute parts must maintain or exceed the 250V voltage rating and 6.3 A current rating to ensure safe operation within the original application envelope.

Fuseholder Type Variation: The substitute parts identified include both clip-type and block-type fuseholders. Both configurations accommodate 5mm cartridge fuses with identical mounting and termination characteristics, representing functional equivalents despite structural differences.

Parameter Comparison

Engineering Selection Recommendations

05200002H (Littelfuse Inc.) - Primary Substitute: This part maintains identical current and voltage ratings (6.3 A, 250V) with active product status. The primary distinction is the fuseholder type (block versus clip) and fuse length specification (5mm x 20mm). Both configurations provide equivalent electrical performance for 5mm cartridge fuses. The part carries ROHS3 compliance and is currently in active production with substantial inventory availability (2300 pcs).

0751.0110 (SCHURTER Inc.) - Secondary Substitute: This clip-type fuseholder matches the original mounting and termination configuration. The current rating is elevated to 10 A, providing margin above the 6.3 A requirement. Voltage rating is not specified in available documentation. The part is active and ROHS3 compliant with extensive inventory (99190 pcs). The higher current rating accommodates applications requiring the original 6.3 A specification.

Both substitute parts satisfy the core mechanical and electrical compatibility requirements for through-hole PCB mounting of 5mm cartridge fuses with PC pin termination.

Frequently Asked Questions (FAQ)

Q: Can the 05200002H block-type fuseholder replace the clip-type BK/HTC-210M? A: Yes. Both are single-circuit, 250V, 6.3 A cartridge fuseholders with through-hole PC pin termination. The block configuration provides equivalent electrical function. Physical space requirements on the PCB must be verified, as block-type holders may have different footprint dimensions than clip-type holders.

Q: Is the 0751.0110 suitable for 6.3 A applications? A: Yes. The 10 A current rating exceeds the 6.3 A requirement. The part accommodates 5mm diameter cartridge fuses with identical mounting and termination. Voltage rating specification is not provided; applications requiring confirmed 250V rating should reference the manufacturer's technical documentation.

Q: What is the difference between clip and block fuseholder types? A: Clip-type holders use spring contacts to retain the fuse cartridge. Block-type holders use a more rigid housing structure. Both accommodate identical fuse dimensions and provide equivalent electrical performance. Selection depends on PCB layout constraints and mechanical retention requirements.

Q: Are all substitute parts RoHS compliant? A: Yes. The BK/HTC-210M is RoHS Compliant. Both substitute parts carry ROHS3 Compliant certification, meeting current regulatory requirements.

Q: What fuse specifications are compatible with these holders? A: All three parts accommodate 5mm diameter cartridge fuses. The 05200002H specifies 5mm x 20mm fuse dimensions. Verify fuse length compatibility with the specific holder design before installation.
