LFPSM0001Z Equivalent & Substitute Parts

Part Overview

The LFPSM0001Z is a 30A 600V cartridge fuse holder manufactured by Littelfuse Inc., designed for DIN rail mounting in single-circuit applications. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance and component procurement. The POWR-GARD® LFPSM series provides protection for midget fuse cartridges (5AG, 13/32" x 1-1/2") in industrial and commercial electrical systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LFPSM0001Z is determined by the following critical parameters:

• Current Rating: 30 A (exact match required)
• Voltage Rating: 600V (exact match required)
• Fuse Size: 0.394" Dia x 1.496" L / 10mm x 38mm (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Number of Circuits: 1 (exact match required)
• Termination Style: Screw Terminal, Pressure Plate (exact match required)
• Fuse Type: Cartridge (exact match required)

The LPSM0001Z qualifies as a direct substitute based on identical electrical ratings, mechanical dimensions, mounting configuration, and termination specifications. Both components are designed for the same 5AG midget cartridge fuse format and operate within identical voltage and current parameters.

Parameter Comparison

Engineering Selection Recommendations

The LPSM0001Z is the direct equivalent replacement for the obsolete LFPSM0001Z. Both components are manufactured by Littelfuse and maintain identical electrical specifications (30A, 600V), mechanical dimensions (10mm x 38mm cartridge), and mounting configuration (DIN rail with screw terminal/pressure plate termination). The LPSM0001Z carries active product status and maintains ROHS3 compliance, making it suitable for new installations and legacy system replacements. No functional or compatibility compromises exist between these two part numbers.

Frequently Asked Questions (FAQ)

Q: Can the LPSM0001Z directly replace the LFPSM0001Z without modification?

A: Yes. Both components share identical electrical ratings (30A, 600V), mechanical dimensions (10mm x 38mm), mounting type (DIN rail), and termination configuration (screw terminal with pressure plate). Direct substitution is supported without circuit or installation modifications.

Q: What is the significance of the product status difference?

A: The LFPSM0001Z is classified as obsolete, indicating discontinued manufacturing. The LPSM0001Z maintains active product status, ensuring ongoing availability, technical support, and compliance with current regulatory standards. For new designs and system replacements, the LPSM0001Z is the recommended selection.

Q: Are there any compliance or certification differences?

A: Both components are ROHS3 compliant. The LPSM0001Z includes documented REACH Unaffected status. No compliance barriers exist for substitution.

Q: What fuse cartridges are compatible with these holders?

A: Both holders accept 5AG midget cartridge fuses with dimensions 13/32" x 1-1/2" (10mm x 38mm). Fuse selection must maintain the 30A current rating and 600V voltage rating for proper circuit protection.

Q: Are there packaging differences between these parts?

A: The LFPSM0001Z is supplied with standard packaging. The LPSM0001Z is supplied in box packaging. This difference does not affect functional compatibility or electrical performance.
