Key Parameters

Substitute Part Grouping Explanation

The BK/HTC-15M qualifies as a functional substitute for the BK/HTC-10M based on the following critical parameters:

Matching Parameters:

• Current Rating: 6.3 A
• Voltage Rating: 250V
• Fuse Size: 5mm x 20mm
• Fuse Type: Cartridge
• Number of Circuits: 1
• Fuseholder Type: Block
• Contact Material: Brass
• Contact Finish: Tin
• Manufacturer: Eaton - Electronics Division
• Series: HTC
• Moisture Sensitivity Level: 1 (Unlimited)

Differing Parameters:

• Mounting Type: Chassis Mount (BK/HTC-10M) vs. Through Hole (BK/HTC-15M)
• Termination Style: Quick Connect (BK/HTC-10M) vs. PC Pin (BK/HTC-15M)
• Product Status: Obsolete (BK/HTC-10M) vs. Active (BK/HTC-15M)

The electrical and mechanical specifications are identical. The primary distinction lies in mounting configuration and termination interface, which must be evaluated against the specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Chassis Mount Applications): The BK/HTC-10M remains the specified component for chassis mount configurations with quick connect termination. However, due to obsolete status, long-term availability is limited. Current inventory of 938 pieces is available.

For Alternative Mounting (Through Hole PCB Applications): The BK/HTC-15M is an active product with superior availability (1485 pieces in stock) and carries ROHS3 compliance certification. This substitute is suitable only for applications where through-hole PCB mounting and PC pin termination are compatible with the circuit design. The electrical performance is identical to the BK/HTC-10M.

Compliance Consideration: The BK/HTC-15M provides ROHS3 compliance and REACH unaffected status, offering regulatory advantages for new designs or systems requiring environmental compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can BK/HTC-15M replace BK/HTC-10M in all applications?

A: No. Substitution is limited to applications where the mounting interface and termination style can be adapted. The BK/HTC-15M uses through-hole PC pins, while the BK/HTC-10M uses chassis mount quick connect. The electrical specifications are identical, but the physical mounting configuration differs.

Q: What are the key electrical parameters that must match for substitution?

A: Current rating (6.3 A), voltage rating (250V), fuse size (5mm x 20mm), and number of circuits (1) must remain constant. Both parts meet these requirements.

Q: Why is the BK/HTC-10M obsolete?

A: Product status is provided as obsolete in the manufacturer data. The BK/HTC-15M is the active equivalent in the HTC series.

Q: Does the BK/HTC-15M require different fuse cartridges?

A: No. Both parts accept the same 5mm x 20mm cartridge fuses. Fuse compatibility is maintained across the substitution.

Q: What is the difference between quick connect and PC pin termination?

A: Quick connect termination (BK/HTC-10M) uses a push-on connector interface for chassis mounting. PC pin termination (BK/HTC-15M) uses through-hole pins for direct PCB soldering. The choice depends on the circuit board design and mounting method.

Q: Is the BK/HTC-15M suitable for new designs?

A: Yes. The BK/HTC-15M is an active product with ROHS3 compliance and REACH unaffected status, making it appropriate for new product development where through-hole mounting is acceptable.
