Key Parameters

Substitute Part Grouping Explanation

The BK/HTB-88I-R has one identified substitute: BK/HTB-36I-R. Both parts are functionally equivalent based on the following critical parameters that determine substitutability:

• Current Rating: Both rated at 20 A
• Voltage Rating: Both rated at 250V
• Fuse Size: Both accommodate 0.25" Dia x 1.26" L (6.35mm x 32mm) cartridges
• Fuse Type: Both are cartridge fuse holders
• Number of Circuits: Both feature 1 circuit
• Mounting Type: Both are panel mount
• Termination Style: Both use Quick Connect - 0.250" (6.3mm)
• Compatible Fuse: Both accept 3AG, 1/4" x 1-1/4" (SFE-20) fuses

The primary difference between these parts is packaging format: BK/HTB-88I-R is supplied in Bulk packaging, while BK/HTB-36I-R is supplied in Box packaging. Both parts are manufactured by Eaton - Electronics Division and maintain the same electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both BK/HTB-88I-R and BK/HTB-36I-R are Active status products manufactured by Eaton - Electronics Division and are suitable for direct substitution in 20 A, 250V cartridge fuse holder applications. Both parts meet RoHS compliance requirements (BK/HTB-88I-R is RoHS Compliant; BK/HTB-36I-R is ROHS3 Compliant). Selection between these parts should be based on packaging requirements and inventory availability. The BK/HTB-36I-R offers higher current inventory (1153 units versus 935 units) and Box packaging, while the BK/HTB-88I-R is available in Bulk packaging. Both parts are electrically and mechanically identical for panel mount cartridge fuse holder applications.

Frequently Asked Questions (FAQ)

Q: Can BK/HTB-36I-R be used as a direct replacement for BK/HTB-88I-R?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical current rating (20 A), voltage rating (250V), fuse size (0.25" Dia x 1.26" L), mounting type (panel mount), termination style (Quick Connect - 0.250"), and circuit configuration (1 circuit). The only difference is packaging format.

Q: What is the difference between Bulk and Box packaging for these fuse holders?

A: Bulk packaging and Box packaging represent different distribution formats. The choice between them depends on application requirements and procurement specifications. Both formats contain the same component with identical electrical and mechanical specifications.

Q: Are both parts RoHS compliant?

A: Yes. BK/HTB-88I-R is RoHS Compliant, and BK/HTB-36I-R is ROHS3 Compliant. Both meet RoHS requirements for restricted substance elimination.

Q: What fuse types are compatible with these holders?

A: Both BK/HTB-88I-R and BK/HTB-36I-R accept 3AG cartridge fuses with dimensions 1/4" x 1-1/4" (SFE-20), which corresponds to the 0.25" Dia x 1.26" L (6.35mm x 32mm) fuse size specification.

Q: Can these fuse holders be used in applications other than panel mount?

A: No. Both parts are specifically designed for panel mount applications. The mounting type is a fixed specification and cannot be altered.

Q: What is the termination method for these fuse holders?

A: Both parts use Quick Connect termination with 0.250" (6.3mm) connectors, providing a standardized connection interface for panel mount installations.
