LFPSM0002ZXID Equivalent & Substitute Parts

Part Overview

The LFPSM0002ZXID is a 30 A, 600V cartridge fuse holder manufactured by Littelfuse Inc. as part of the POWR-GARD® LFPSM series. This component is designed for DIN rail mounting and accommodates 5AG midget fuses (10mm x 38mm). The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance and component replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LFPSM0002ZXID is determined by the following critical parameters:

• Current Rating: 30 A (must match exactly)
• Voltage Rating: 600V (must match exactly)
• Fuse Size: 10mm x 38mm cartridge (must match exactly)
• Mounting Type: DIN Rail (must match exactly)
• Termination Style: Screw Terminal, Pressure Plate (must match exactly)
• Fuse Type: Cartridge, 5AG midget specification (must match exactly)

The LPSM0002ZXID qualifies as a direct substitute based on these core electrical and mechanical parameters. The primary difference between the main part and substitute is the number of circuits: the LFPSM0002ZXID provides 3 circuits, while the LPSM0002ZXID provides 2 circuits. Both parts share identical voltage, current, fuse size, mounting configuration, and termination specifications.

Parameter Comparison

Engineering Selection Recommendations

The LPSM0002ZXID is the direct substitute for the obsolete LFPSM0002ZXID. Both components maintain identical electrical ratings (30 A, 600V), mechanical compatibility (10mm x 38mm cartridge fuse accommodation), and mounting specifications (DIN rail with screw terminal/pressure plate termination).

The LPSM0002ZXID carries Active product status, ensuring ongoing availability and support. Both parts meet ROHS3 compliance requirements and share equivalent moisture sensitivity ratings. The substitute part is currently in stock with 863 units available.

The circuit count difference (3 circuits vs. 2 circuits) must be evaluated against system requirements. If the application requires exactly 3 independent circuits, the LPSM0002ZXID may not be suitable without additional circuit configuration modifications. If the application can operate with 2 circuits, the LPSM0002ZXID provides a direct functional replacement.

Frequently Asked Questions (FAQ)

Q: Can the LPSM0002ZXID directly replace the LFPSM0002ZXID in all applications?

A: The LPSM0002ZXID matches all critical electrical and mechanical parameters: 30 A current rating, 600V voltage rating, 10mm x 38mm fuse size, DIN rail mounting, and screw terminal/pressure plate termination. The difference in circuit count (2 vs. 3) must be verified against your specific application requirements before substitution.

Q: What is the significance of the circuit count difference?

A: The LFPSM0002ZXID provides 3 independent circuits for fuse protection, while the LPSM0002ZXID provides 2 circuits. This affects how many separate load paths can be independently protected. Verify your system design to confirm whether 2 or 3 circuits are required.

Q: Are both parts compatible with the same fuse cartridges?

A: Yes. Both the LFPSM0002ZXID and LPSM0002ZXID accommodate 5AG midget cartridge fuses with dimensions of 10mm x 38mm (0.394" Dia x 1.496" L).

Q: What is the product status difference, and why does it matter?

A: The LFPSM0002ZXID is obsolete, meaning Littelfuse Inc. no longer manufactures or supports this part. The LPSM0002ZXID is Active, ensuring continued availability, technical support, and compliance with current standards. For new designs or long-term system support, the Active substitute is preferred.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant and carry identical MSL ratings (1, Unlimited). Both meet the same environmental and regulatory standards.

Q: What packaging is available for the substitute part?

A: The LPSM0002ZXID is supplied in Box packaging with 863 units currently in stock.
