Substitute Part Grouping Explanation

Substitution of the BK/HTB-86I is determined by strict equivalence across the following critical parameters:

• Current Rating: 20 amperes (exact match required)
• Voltage Rating: 250 volts (exact match required)
• Fuse Size: 0.25" diameter x 1.26" length / 6.35mm x 32mm (exact match required)
• Fuse Type: Cartridge configuration (exact match required)
• Number of Circuits: Single circuit (exact match required)
• Mounting Configuration: Panel mount orientation (exact match required)
• Termination Interface: Quick connect 0.250" (6.3mm) terminals (exact match required)

The substitute part BK/HTB-86I-R maintains identical electrical and mechanical specifications across all parameters listed above, confirming direct substitutability within the HTB series from Eaton - Electronics Division.

Parameter Comparison

Engineering Selection Recommendations

BK/HTB-86I is suitable for applications where RoHS non-compliant components are acceptable. This part maintains Active product status and is available in inventory (857 pcs).

BK/HTB-86I-R is the preferred substitute when regulatory compliance with ROHS3 standards is required. This variant is REACH Unaffected and maintains all identical electrical and mechanical specifications. Higher inventory availability (1572 pcs) supports supply chain reliability. Selection of BK/HTB-86I-R is indicated for new designs, applications subject to EU environmental directives, or when long-term component availability is a consideration.

Both parts are functionally equivalent for 20A, 250V cartridge fuse holder applications with panel mount configuration and quick connect termination.

Frequently Asked Questions (FAQ)

Q: Can BK/HTB-86I-R be used as a direct replacement for BK/HTB-86I in existing assemblies?

A: Yes. The BK/HTB-86I-R maintains identical electrical ratings (20A, 250V), mechanical dimensions (0.25" x 1.26"), fuse type (cartridge), mounting configuration (panel mount), and termination style (quick connect 0.250"). No circuit redesign or mechanical modification is required.

Q: What is the primary difference between these two parts?

A: The BK/HTB-86I-R is ROHS3 compliant and REACH Unaffected, while the BK/HTB-86I is RoHS non-compliant. All functional and mechanical parameters are identical.

Q: Are these parts compatible with the same fuse cartridges?

A: Yes. Both holders accommodate 3AG cartridge fuses rated 1/4" x 1-1/4" (SFE-20 standard), 20 amperes, 250 volts.

Q: Which part should be selected for new product designs?

A: BK/HTB-86I-R is recommended for new designs due to ROHS3 compliance and REACH Unaffected status, ensuring alignment with current regulatory requirements and long-term market acceptance.

Q: Is there any difference in termination compatibility?

A: No. Both parts feature identical quick connect termination at 0.250" (6.3mm), ensuring compatibility with the same panel mount wiring interfaces.

Q: What is the inventory status for each part?

A: BK/HTB-86I has 857 pcs in stock. BK/HTB-86I-R has 1572 pcs in stock, providing greater availability for supply chain planning.
