Key Parameters

Substitute Part Grouping Explanation

Substitution between LFPSM0003Z and LPSM0003Z is based on strict equivalence across all critical electrical and mechanical parameters. Both components share identical current rating (30 A), voltage rating (600V), circuit count (3), fuse size (10mm x 38mm), mounting configuration (DIN rail), and termination style (screw terminal with pressure plate). The primary distinction is product status: LFPSM0003Z is obsolete while LPSM0003Z maintains active manufacturing status. Both comply with ROHS3 and carry identical ECCN and HTSUS classifications, confirming regulatory and trade equivalence.

Parameter Comparison

Engineering Selection Recommendations

LPSM0003Z is the direct equivalent for LFPSM0003Z applications. Selection is determined by product status and supply chain availability. LFPSM0003Z, classified as obsolete, should be replaced with LPSM0003Z for new procurement and system maintenance. Both components maintain identical electrical performance (30A, 600V, 3-circuit configuration) and mechanical compatibility (DIN rail mounting, 10mm x 38mm cartridge fuse accommodation). LPSM0003Z carries active manufacturing status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. No functional differences exist between the two components; selection is based on procurement feasibility and supply continuity.

Frequently Asked Questions (FAQ)

Q: Can LPSM0003Z directly replace LFPSM0003Z in existing installations? A: Yes. Both components are electrically and mechanically identical across all specified parameters: 30A current rating, 600V voltage rating, 3-circuit configuration, DIN rail mounting, and screw terminal termination. Direct substitution is supported without modification.

Q: What is the primary reason for substitution? A: LFPSM0003Z is classified as obsolete. LPSM0003Z is the active-status equivalent, ensuring continued availability and manufacturing support.

Q: Are there compatibility differences in fuse accommodation? A: No. Both components accept identical 5AG midget cartridge fuses (13/32" x 1-1/2" / 10mm x 38mm). Fuse compatibility is unchanged.

Q: Do both components meet current regulatory requirements? A: Yes. Both LFPSM0003Z and LPSM0003Z are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications.

Q: Are there packaging differences between the two parts? A: LFPSM0003Z is supplied with standard packaging; LPSM0003Z is supplied in box packaging. This does not affect functional or mechanical compatibility.

Q: What is the moisture sensitivity level for both components? A: Both components carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
