Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the USM2 are identified based on electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Voltage rating of 600V
• Current rating of 30A
• Two-circuit (2-pole) configuration
• Cartridge fuse holder design
• DIN rail mounting capability
• ROHS3 compliance status

The LPSM0002Z from Littelfuse Inc. meets these core electrical and mechanical requirements, making it a valid substitute within the POWR-GARD® LPSM series. Both components are designed to accommodate the same fuse specifications and operate within identical voltage and current parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the USM2 and LPSM0002Z are active products with ROHS3 compliance certification. The LPSM0002Z provides additional documented specifications including DIN rail mounting, screw terminal and pressure plate termination, and fuse dimensions of 10mm x 38mm (5AG, 13/32" x 1-1/2" midget cartridge). Selection between these components should be based on specific application requirements, available inventory, and design integration needs. Both components satisfy the core electrical parameters of 600V, 30A, 2-circuit operation.

Frequently Asked Questions (FAQ)

Q: What makes the LPSM0002Z a valid substitute for the USM2?

A: The LPSM0002Z meets the critical electrical parameters: 600V voltage rating, 30A current rating, and 2-circuit configuration. Both components are cartridge fuse holders with active product status and ROHS3 compliance.

Q: Are there mechanical compatibility considerations between USM2 and LPSM0002Z?
