Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0LS03033Z is determined by the following critical parameters:

• Electrical Ratings: Voltage (600 V) and current capacity (310 A) must match or exceed the original specification
• Pole Configuration: 3-pole requirement must be maintained
• Wire Gauge Compatibility: 350 MCM (kcmil) #6 CU/AL accommodation on both line and load sides
• Connection Method: Screw-type terminals on both sides
• Regulatory Compliance: RoHS3 and REACH status alignment

The substitute part 0LS45823ZX meets these criteria as an active Littelfuse product within the same terminal block category, maintaining electrical and mechanical compatibility with the obsolete 0LS03033Z.

Parameter Comparison

Engineering Selection Recommendations

The 0LS45823ZX is the manufacturer-recommended substitute for the obsolete 0LS03033Z. Both parts maintain identical electrical ratings (310 A, 600 V) and pole configuration (3-pole). The substitute part carries active product status, ensuring availability and continued manufacturer support. Both components satisfy ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial terminal block applications. Selection of the 0LS45823ZX provides functional equivalence with the advantage of active product lifecycle support.

Frequently Asked Questions (FAQ)

Q: Can the 0LS45823ZX directly replace the 0LS03033Z in existing installations?

A: Yes. Both parts share identical electrical ratings (310 A, 600 V), 3-pole configuration, and screw connection terminals. The substitute maintains compatibility with 350 MCM (kcmil) #6 CU/AL wire sizes on both line and load sides.
