Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0LS25723Z is determined by the following critical parameters:

• Electrical Ratings: Voltage rating of 600 V and current rating of 175 A must be maintained or exceeded
• Mechanical Configuration: 3-pole architecture with single connection per pole on both line and load sides
• Connection Method: Screw-type connections on both sides
• Wire Gauge Compatibility: Support for 2/0 to #14 AWG copper or aluminum conductors
• Series Compatibility: Components within the POWR-BLOKS® family maintain consistent mechanical and electrical interfaces

The substitute part LFS25723Z meets all these criteria while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The LFS25723Z is the direct substitute for the obsolete 0LS25723Z. Both components share identical electrical ratings (600 V, 175 A), mechanical configuration (3-pole), and connection methodology (screw-type on both sides). The LFS25723Z offers the following advantages:

• Active Product Status: Currently manufactured and supported by Littelfuse Inc., ensuring long-term availability and supply chain reliability
• Regulatory Compliance: ROHS3 compliant and REACH unaffected, meeting current environmental and safety standards
• Load Side Wire Gauge: Supports 2 - #14 CU/AL, providing compatibility with standard conductor sizes in power distribution applications

The load side wire/stud size specification for LFS25723Z (2 - #14 CU/AL) differs from the main part (2/0 - #14 CU/AL) only at the upper range. This difference does not affect substitution for applications using standard conductor sizes up to 2 AWG.

Frequently Asked Questions (FAQ)

Q: Can LFS25723Z directly replace 0LS25723Z in existing installations?

A: Yes. Both components maintain identical electrical ratings (600 V, 175 A), pole configuration (3-pole), and screw connection types. Mechanical and electrical compatibility is assured for applications using conductors within the 2 - #14 AWG range.

Q: What is the significance of the product status change from Obsolete to Active?

A: The obsolete status of 0LS25723Z indicates it is no longer manufactured. The LFS25723Z, being active, is currently produced and supported by Littelfuse Inc., ensuring availability for replacement and new installations.

Q: Does the load side wire/stud size difference affect compatibility?

A: The LFS25723Z load side specification (2 - #14 CU/AL) covers standard conductor sizes used in most power distribution applications. If your application requires 2/0 AWG conductors on the load side, consult with Littelfuse Inc. for alternative solutions.

Q: Are there compliance differences between the two parts?

A: Yes. The LFS25723Z is ROHS3 compliant and REACH unaffected, while the 0LS25723Z is RoHS non-compliant. For applications subject to environmental regulations, the LFS25723Z is the appropriate choice.

Q: What packaging is available for the substitute part?

A: The LFS25723Z is supplied in box packaging, suitable for standard distribution and installation workflows.
