Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HTB-48M-R is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Current rating (16 A), voltage rating (250V), and single-circuit configuration must be identical.

Mechanical Specifications: Fuse size (5mm x 20mm cartridge), panel mount orientation, and quick connect termination (0.250" / 6.3mm) must match exactly.

Functional Classification: Fuseholder type and cartridge fuse compatibility must be maintained.

Compliance & Status: Product must maintain Active status and RoHS compliance certification.

The substitute part BK/HTB-48M-R meets all substitution criteria through identical electrical and mechanical parameters, series designation, and functional specifications.

Parameter Comparison

Engineering Selection Recommendations

Both HTB-48M-R and BK/HTB-48M-R are Active status products from Eaton - Electronics Division with full RoHS compliance. The BK/HTB-48M-R carries ROHS3 certification, indicating compliance with the most current RoHS directive iteration. Both parts maintain identical electrical ratings (16 A, 250V), mechanical dimensions (5mm x 20mm cartridge), and termination specifications (quick connect 0.250" / 6.3mm).

Selection between these parts is based on inventory availability and compliance certification requirements. The BK/HTB-48M-R variant with ROHS3 certification is suitable for applications requiring the latest RoHS compliance documentation. Both parts are functionally interchangeable for 16 A, 250V single-circuit cartridge fuse holder applications with panel mount configuration.

Frequently Asked Questions (FAQ)

Q: Can BK/HTB-48M-R be used as a direct replacement for HTB-48M-R?

A: Yes. Both parts are electrically and mechanically identical with matching current ratings (16 A), voltage ratings (250V), fuse sizes (5mm x 20mm), mounting types (panel mount), and termination styles (quick connect 0.250" / 6.3mm).

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

A: ROHS3 represents compliance with the most current RoHS directive revision. Both certifications indicate hazardous substance restrictions are met. The BK/HTB-48M-R carries the newer ROHS3 designation.

Q: Are these parts compatible with different fuse sizes?

A: No. Both HTB-48M-R and BK/HTB-48M-R are designed exclusively for 5mm x 20mm cartridge fuses. Different fuse sizes require different holder models.

Q: What does the "BK/" prefix in BK/HTB-48M-R indicate?

A: The BK/ prefix is a manufacturer variant designation from Eaton - Electronics Division. It does not affect electrical or mechanical specifications.

Q: Can these holders be used in applications rated above 250V?

A: No. Both parts are rated for maximum 250V operation. Higher voltage applications require different holder models with appropriate voltage ratings.

Q: What is the quick connect termination specification?

A: Quick connect termination uses 0.250" (6.3mm) spade connectors for direct connection to panel-mounted circuits without soldering.
