Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0LD14004Z is determined by strict equivalence across the following critical parameters:

• Electrical Ratings: Voltage (600 V) and current capacity (115 A) must match exactly
• Pole Configuration: 4-pole architecture with identical connection topology
• Connection Architecture: 1 line-side connection per pole and 4 load-side connections per pole
• Wire Gauge Compatibility: Line side #14 CU/AL and load side #18 CU/AL specifications
• Connection Method: Screw-type terminals on both line and load sides
• Series Compatibility: POWR-BLOKS® LD series maintains mechanical and electrical interchangeability

The substitute part 0LD14404Z meets all these criteria while offering active product status and improved availability.

Frequently Asked Questions (FAQ)

Q: Can the 0LD14404Z directly replace the 0LD14004Z in existing installations?

A: Yes. Both components share identical electrical ratings (115 A, 600 V), pole configuration (4-pole), connection topology (1 line-side, 4 load-side per pole), wire gauge specifications (#14 CU/AL line side, #18 CU/AL load side), and screw-type terminal design. They are mechanically and electrically interchangeable within the POWR-BLOKS® LD series.

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

A: The 0LD14004Z is classified as obsolete, while the 0LD14404Z maintains active product status. The 0LD14404Z is designated as a power splicer terminal block variant, whereas the 0LD14004Z is a power distribution block. Both function identically for the specified electrical and mechanical parameters.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings. No compliance or certification differences exist between the two components.

Q: What packaging options are available?

A: The 0LD14004Z was supplied without specified packaging. The 0LD14404Z is available in bulk packaging, suitable for production environments and high-volume applications.

Q: Are both parts suitable for 600 V, 115 A applications?

A: Yes. Both the 0LD14004Z and 0LD14404Z are rated for 600 V operation at 115 A continuous current capacity.
