Substitute Part Grouping Explanation

Substitution of the LFPSM0004ZXID is determined by strict equivalence across 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)
• 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 LPSM0004ZXID 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.

Parameter Comparison

Engineering Selection Recommendations

The LPSM0004ZXID is the appropriate substitute for the obsolete LFPSM0004ZXID. Both components are ROHS3 compliant and carry identical electrical ratings, mechanical dimensions, and termination specifications. The LPSM0004ZXID maintains active product status with current manufacturing availability, eliminating supply chain risk associated with the obsolete LFPSM0004ZXID. No functional or performance differences exist between the two models. Selection of the LPSM0004ZXID is based on product continuity and regulatory compliance equivalence.

Frequently Asked Questions (FAQ)

Q: Can the LPSM0004ZXID be used as a direct replacement for the LFPSM0004ZXID?

A: Yes. Both components share identical electrical ratings (30A, 600V), mechanical dimensions (10mm x 38mm cartridge), circuit count (4), mounting configuration (DIN rail), and termination style (screw terminal with pressure plate). No modifications to the installation or circuit design are required.

Q: What is the primary reason for substitution?

A: The LFPSM0004ZXID is classified as obsolete. The LPSM0004ZXID is the active-status equivalent from the same manufacturer, ensuring continued availability and manufacturing support.

Q: Are there any packaging differences between these components?

A: The LFPSM0004ZXID is supplied without specified packaging notation, while the LPSM0004ZXID is packaged in boxes. This difference does not affect electrical or mechanical compatibility.

Q: Do both components support the same fuse cartridge type?

A: Yes. Both holders accommodate 5AG midget cartridge fuses with dimensions 0.394" diameter x 1.496" length (10mm x 38mm). Fuse compatibility is identical.

Q: Are regulatory certifications equivalent?

A: Yes. Both components are ROHS3 compliant with MSL rating 1 (unlimited moisture sensitivity level) and carry identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications.
