Substitute Part Grouping Explanation

Substitution of the 0LD25702Z is based on electrical and mechanical parameter equivalence within the Littelfuse POWR-BLOKS® product family. The substitute part must maintain identical specifications across the following critical parameters:

  • 2-pole configuration with 1 line-side connection and 4 load-side connections per pole
  • 175 A current rating at 600 V voltage rating
  • Screw connection type on both line and load sides
  • Wire/stud size compatibility: 2/0 - #14 CU/AL (line side) and 4 - #14 CU/AL (load side)
  • RoHS3 compliance and MSL 1 rating

The LFD25702Z meets all these requirements and represents the active-status equivalent within the POWR-BLOKS® product line.

Engineering Selection Recommendations

The LFD25702Z is the direct substitute for the obsolete 0LD25702Z. Both components are manufactured by Littelfuse Inc. and maintain identical electrical and mechanical specifications. The LFD25702Z carries active product status, ensuring ongoing availability and support. Both parts are ROHS3 compliant and carry equivalent regulatory classifications (ECCN: EAR99, HTSUS: 8538.90.8180). The transition from the LD series to the LF series represents a product line evolution within the POWR-BLOKS® family, with no functional or performance differences in the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can the LFD25702Z be used as a direct replacement for the 0LD25702Z?

A: Yes. The LFD25702Z is electrically and mechanically equivalent to the 0LD25702Z. Both components share identical pole configuration, current and voltage ratings, connection types, and wire/stud size specifications.

Q: What is the difference between the LD and LF series designations?

A: The LD and LF series are both part of the Littelfuse POWR-BLOKS® product family. The LFD25702Z represents the current active product line, while the 0LD25702Z is from the obsolete LD series. The functional specifications remain identical.

Q: Are there packaging differences between these parts?

A: The 0LD25702Z packaging information is not specified in the available data. The LFD25702Z is supplied in box packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 0LD25702Z and LFD25702Z are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Both carry the same ECCN and HTSUS classifications.

Q: What wire gauges are compatible with these terminal blocks?

A: Line-side connections accept 2/0 - #14 CU/AL wire or stud sizes. Load-side connections accept 4 - #14 CU/AL wire or stud sizes. Both the main part and substitute maintain these specifications.
