Parameter Comparison

Engineering Selection Recommendations

The 0LD14402Z is the direct substitute for the obsolete 0LD14002Z. Both components maintain identical electrical ratings (115 A, 600 V), pole configuration (2 poles), and connection specifications. The 0LD14402Z offers the advantage of Active product status, ensuring long-term availability and manufacturer support. Both parts are ROHS3 Compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, meeting equivalent environmental and regulatory requirements. The transition from the obsolete 0LD14002Z to the 0LD14402Z presents no functional or performance degradation in applications requiring 2-pole power distribution or splicing at 115 A and 600 V.

Frequently Asked Questions (FAQ)

Q: Can the 0LD14402Z directly replace the 0LD14002Z in existing installations?

A: Yes. Both parts share identical electrical ratings (115 A, 600 V), pole count (2), and connection specifications (screw connections with matching wire/stud sizes). The 0LD14402Z is functionally equivalent and mechanically compatible.

Q: What is the difference between a Power Distribution Block and a Power Splicer Terminal Block?

A: Both designations refer to components within the POWR-BLOKS® LD series with identical electrical and mechanical parameters. The functional difference lies in application context: distribution blocks manage power flow to multiple loads, while splicer blocks join multiple conductors. For the specified parameters, both perform equivalent terminal block functions.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the 0LD14002Z and 0LD14402Z are ROHS3 Compliant with MSL 1 (Unlimited) ratings. The 0LD14402Z carries additional REACH Unaffected status, indicating no regulatory restrictions on use.

Q: Why is the 0LD14002Z listed as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 0LD14402Z remains in Active production, making it the recommended choice for new designs and replacement applications.

Q: Are packaging differences significant for selection?

A: The 0LD14002Z packaging is unspecified in available data, while the 0LD14402Z is supplied in Bulk packaging. Packaging does not affect electrical or mechanical compatibility; selection should be based on procurement and inventory requirements.
