Key Parameters

Substitute Part Grouping Explanation

Substitution of the LFPSM0004Z is determined by strict equivalence across the following parameters:

• Current Rating: 30 A (exact match required)
• Voltage Rating: 600V (exact match required)
• Fuse Size: 10mm x 38mm cartridge (exact match required)
• Number of Circuits: 4 (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Termination Style: Screw Terminal, Pressure Plate (exact match required)
• Fuse Type: Cartridge, 5AG midget format (exact match required)

The LPSM0004Z meets all substitution criteria as a direct equivalent. Both components are manufactured by Littelfuse Inc. within the POWR-GARD® series and share identical electrical and mechanical specifications. The primary distinction is product status: LFPSM0004Z is obsolete, while LPSM0004Z is active production.

Parameter Comparison

Engineering Selection Recommendations

The LPSM0004Z is the appropriate substitute for the obsolete LFPSM0004Z. Both components are ROHS3 compliant and share identical electrical ratings, mechanical dimensions, and termination specifications. The LPSM0004Z maintains active production status, ensuring availability for procurement and future system support. No functional differences exist between the two components; selection of LPSM0004Z eliminates obsolescence risk while preserving full system compatibility.

Frequently Asked Questions (FAQ)

Q: Can LPSM0004Z be used as a direct replacement for LFPSM0004Z?

A: Yes. The LPSM0004Z is a direct equivalent substitute. Both components share identical current rating (30A), voltage rating (600V), fuse size (10mm x 38mm), circuit count (4), mounting type (DIN Rail), and termination style (Screw Terminal, Pressure Plate). No modifications to the installation or circuit design are required.

Q: What is the primary reason to substitute LFPSM0004Z?

A: The LFPSM0004Z is classified as obsolete. The LPSM0004Z provides an active production alternative with identical specifications, ensuring long-term component availability and supply chain continuity.

Q: Are there any compliance or certification differences between these parts?

A: No. Both components are ROHS3 compliant, carry MSL rating 1 (Unlimited), and share identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications.

Q: What fuse types are compatible with these holders?

A: Both holders accept 5AG cartridge fuses in the 13/32" x 1-1/2" (10mm x 38mm) midget format, rated for 600V operation.

Q: Are there packaging differences between LFPSM0004Z and LPSM0004Z?

A: The LPSM0004Z is supplied in box packaging. Packaging format does not affect electrical or mechanical compatibility.
