Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HTB-64M-R fuse holder is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Current rating: 16 A
• Voltage rating: 250V
• Number of circuits: 1

Mechanical Specifications:

• Fuse size: 5mm x 20mm cartridge
• Mounting configuration: Panel mount
• Termination interface: Quick connect 0.187" (4.7mm)

Compliance & Environmental:

• RoHS compliance status
• Moisture sensitivity level: 1 (Unlimited)

Parts meeting all these criteria are classified as direct substitutes. Variations in manufacturer part number designation, packaging quantity, or inventory status do not affect substitution eligibility when all electrical, mechanical, and compliance parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

HTB-64M-R (Primary Part Number)

• Active product status with established supply chain
• RoHS Compliant certification
• Current inventory: 897 pieces
• Suitable for new designs and production applications

BK/HTB-64M-R (Direct Substitute)

• Active product status with equivalent supply availability
• ROHS3 Compliant certification (enhanced RoHS standard)
• Current inventory: 1,013 pieces
• REACH Unaffected status provides additional regulatory clarity
• Functionally and mechanically identical to HTB-64M-R

Both part numbers are interchangeable in applications requiring a 16 A, 250V single-circuit cartridge fuse holder with 5mm x 20mm fuse accommodation and panel mount configuration. Selection between the two may be based on inventory availability, supply chain preference, or specific regulatory documentation requirements. The BK/HTB-64M-R variant offers higher current inventory levels and explicit REACH compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can BK/HTB-64M-R be used as a direct replacement for HTB-64M-R in existing designs?

A: Yes. Both part numbers are manufactured by Eaton - Electronics Division with identical electrical ratings (16 A, 250V), mechanical dimensions (5mm x 20mm cartridge fuse accommodation), mounting configuration (panel mount), and termination interface (quick connect 0.187"). All compliance certifications are equivalent or enhanced.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: ROHS3 represents the third iteration of RoHS compliance standards with updated substance restrictions. Both designations indicate compliance with hazardous substance limitations. ROHS3 Compliant reflects the current regulatory standard and provides forward compatibility with evolving environmental requirements.

Q: Are the quick connect terminations identical between HTB-64M-R and BK/HTB-64M-R?

A: Yes. Both parts feature Quick Connect - 0.187" (4.7mm) termination, ensuring identical mating with standard 0.187" quick disconnect connectors used in panel mount fuse holder applications.

Q: What fuse types are compatible with these holders?

A: Both holders accommodate 5mm x 20mm cartridge fuses. Fuse selection must match the 16 A current rating and 250V voltage rating of the holder to maintain circuit protection integrity.

Q: Does moisture sensitivity level affect substitution eligibility?

A: No. Both parts share Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions during storage, transport, or installation. This parameter is identical across both part numbers.

Q: Can these fuse holders be used in non-panel mount applications?

A: No. Both HTB-64M-R and BK/HTB-64M-R are specifically designed for panel mount installation. Alternative mounting configurations require different holder designs.
