Substitute Part Grouping Explanation

Substitution of the LG300152SQ is based on electrical and mechanical compatibility across the following critical parameters:

• Voltage rating: 600V (must match exactly)
• Current rating: 15 A (must match exactly)
• Fuse size: 0.394" Dia x 1.313" L (10mm x 33.35mm) (must match exactly)
• Fuse type: Cartridge (must match exactly)
• Number of circuits: 2 (must match exactly)
• Fuseholder type: Block (must match exactly)
• Accepted fuse standard: Class G, 13/32" x 1-5/16" (must match exactly)

The primary difference between the main part and its substitute is the mounting configuration. The LG300152SQ uses chassis mount, while the substitute uses DIN rail mounting. Both maintain identical electrical specifications and fuse acceptance criteria, allowing substitution in applications where the mounting method can be adapted.

Parameter Comparison

Engineering Selection Recommendations

The LFG600152SQDINR serves as the direct substitute for the obsolete LG300152SQ. Both components maintain identical electrical and mechanical specifications for fuse acceptance and circuit protection. The LFG600152SQDINR is classified as active product status, ensuring continued availability and supply chain reliability.

The LFG600152SQDINR achieves ROHS3 compliance, whereas the LG300152SQ is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulations. The primary design difference is mounting configuration: the LG300152SQ uses chassis mount while the LFG600152SQDINR uses DIN rail mounting. Selection between these configurations depends on the mechanical installation requirements of the target application.

Both components feature identical moisture sensitivity levels and accept the same Class G fuse specifications, ensuring functional interchangeability in electrical circuit protection applications.

Frequently Asked Questions (FAQ)

Q: Can the LFG600152SQDINR directly replace the LG300152SQ in existing installations?

A: Electrical substitution is valid. Both components accept identical fuse types and ratings. Mechanical installation requires adaptation due to different mounting methods: the LG300152SQ uses chassis mount while the LFG600152SQDINR uses DIN rail mounting.

Q: What fuse types are compatible with both the LG300152SQ and LFG600152SQDINR?

A: Both fuse blocks accept Class G fuses in 13/32" x 1-5/16" format with 15A rating at 600V.

Q: Are there compliance differences between these two parts?

A: Yes. The LFG600152SQDINR is ROHS3 compliant, while the LG300152SQ is RoHS non-compliant. For applications requiring RoHS compliance, the LFG600152SQDINR is the appropriate selection.
