Littelfuse 01500145Z Fuse Holder Cartridge 32V 20A In-Line

Part Overview

The Littelfuse 01500145Z is an active-status cartridge fuse holder rated for 20 A at 32V, designed for single-circuit free-hanging in-line applications. This component accommodates 0.25" diameter cartridge fuses ranging from 0.625" to 1.26" in length, including 1AG, 3AG, 7AG, 8AG, SFE-14, and SFE-6 fuse types. The holder features brass contacts with tin finish and wire lead termination, making it suitable for inline circuit protection in industrial and commercial equipment. Alternative models may be required when application constraints demand different current ratings, fuse size compatibility, or specific supplier availability.

Key Parameters

Substitute Part Grouping Explanation

The Eaton BK/HRK-R cartridge fuse holder qualifies as a substitute based on the following shared electrical and mechanical parameters:

Substitution Criteria:

• Voltage rating: Both rated at 32V
• Fuse type: Both accommodate cartridge fuses
• Number of circuits: Both single-circuit designs
• Mounting configuration: Both free-hanging in-line orientation
• Termination: Both feature wire leads
• Regulatory compliance: Both ROHS3 compliant and REACH unaffected

Functional Difference: The BK/HRK-R operates at 15 A current rating versus the 01500145Z at 20 A. This substitution is valid only when circuit protection requirements permit the lower current rating. Fuse size compatibility differs: the BK/HRK-R accommodates 0.25" diameter fuses from 0.875" to 1.26" length, while the 01500145Z accepts fuses from 0.625" to 1.26" length.

Parameter Comparison

Engineering Selection Recommendations

Both the Littelfuse 01500145Z and Eaton BK/HRK-R maintain active product status and full compliance with ROHS3 and REACH regulations, ensuring regulatory acceptability in current applications. Selection between these components depends on circuit protection requirements and fuse availability constraints.

The 01500145Z is the primary choice for circuits requiring 20 A protection or when fuse sizes smaller than 0.875" length are necessary. The BK/HRK-R serves as a substitute only when the application circuit can operate safely at 15 A protection and fuse sizes remain within the 0.875" to 1.26" length range. Both holders maintain identical voltage ratings, mounting configurations, and termination styles, ensuring mechanical and electrical compatibility within their respective current and fuse size parameters.

Frequently Asked Questions (FAQ)

Q: Can the Eaton BK/HRK-R directly replace the Littelfuse 01500145Z in all applications?

A: No. The BK/HRK-R operates at 15 A versus the 01500145Z at 20 A. Substitution is valid only when the circuit protection requirement permits the lower current rating. Additionally, the BK/HRK-R does not accommodate fuses shorter than 0.875" length.

Q: What fuse types are compatible with each holder?

A: The 01500145Z accepts 1AG, 3AG, 7AG, 8AG, SFE-14, and SFE-6 cartridge fuses. The BK/HRK-R accommodates 3AG, 7AG, 8AG, and 1/4" x 7/8" ~ 1-1/4" cartridge fuses. Verify fuse type compatibility before substitution.

Q: Are both holders suitable for in-line circuit protection applications?

A: Yes. Both the 01500145Z and BK/HRK-R feature free-hanging in-line mounting configurations with wire lead termination, making them suitable for inline circuit protection in equivalent applications.

Q: Do both holders meet current regulatory requirements?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component applications.

Q: What is the voltage rating for both fuse holders?

A: Both the Littelfuse 01500145Z and Eaton BK/HRK-R are rated for 32V operation.
