Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0LD04013Z is determined by strict equivalence across the following critical parameters:

• Electrical Performance: Voltage rating (600 V) and current capacity (175 A) must match exactly
• Pole Configuration: 3-pole architecture is mandatory
• Connection Architecture: 1 line-side connection and 6 load-side connections per pole must be maintained
• Connection Method: Screw-type connections on both line and load sides
• Wire/Stud Compatibility: Line side (2/0 - #14 CU/AL) and load side (4 - #14 CU/AL) sizing must be identical
• Regulatory Compliance: ROHS3 compliance and MSL 1 rating must be preserved

The LFD04013Z meets all substitution criteria as a direct equivalent within the Littelfuse POWR-BLOKS® product family.

Parameter Comparison

Engineering Selection Recommendations

The LFD04013Z is the direct substitute for the obsolete 0LD04013Z. Both components are manufactured by Littelfuse and maintain identical electrical specifications, pole configuration, connection architecture, and wire sizing requirements.

The LFD04013Z carries active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain ROHS3 compliance and MSL 1 rating, meeting current regulatory requirements. The transition from the LD series to the LF series represents a product line evolution within the POWR-BLOKS® family while preserving all functional and electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can the LFD04013Z be used as a direct replacement for the 0LD04013Z?

A: Yes. The LFD04013Z is electrically and mechanically equivalent to the 0LD04013Z. Both components share identical voltage ratings (600 V), current capacity (175 A), pole configuration (3-pole), connection types (screw), and wire sizing specifications.

Q: What is the primary difference between these two parts?

A: The 0LD04013Z belongs to the POWR-BLOKS® LD series and carries obsolete status. The LFD04013Z belongs to the POWR-BLOKS® LF series and maintains active product status. No functional or electrical differences exist between the two models.

Q: Are there any packaging or compliance differences?

A: Both parts are ROHS3 compliant with MSL 1 rating. The LFD04013Z is supplied in box packaging. Both share identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications.

Q: What wire gauges are compatible with each connection type?

A: Line-side connections accept wire/stud sizes from 2/0 to #14 (copper or aluminum). Load-side connections accept wire/stud sizes from 4 to #14 (copper or aluminum).

Q: Is the LFD04013Z available in stock?

A: The LFD04013Z is listed as active product status with 987 pieces in new original stock inventory.
