Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0LS13002Z with the 0LS13302Z is valid based on the following criteria:

Electrical Compatibility: Both parts maintain identical voltage rating (600 V) and current rating (115 A), ensuring equivalent performance in power distribution circuits.

Mechanical Compatibility: Both parts feature 2 poles with single line-side and load-side connections per pole, identical screw connection types, and matching wire/stud size specifications (#14 CU/AL on both sides).

Environmental Specifications: Both parts share MSL rating of 1 (Unlimited), indicating identical moisture sensitivity characteristics.

Series Continuity: Both parts belong to the Littelfuse POWR-BLOKS® LS series, confirming design family alignment.

The primary distinction is product status: the 0LS13002Z is obsolete, while the 0LS13302Z is active with improved RoHS3 compliance and REACH unaffected status.

Engineering Selection Recommendations

The 0LS13302Z is the direct substitute for the obsolete 0LS13002Z. Selection of the 0LS13302Z is supported by:

Product Availability: The 0LS13302Z maintains active product status with 1052 units in stock, compared to the obsolete 0LS13002Z with limited remaining inventory of 974 units.

Regulatory Compliance: The 0LS13302Z achieves RoHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for new designs and procurement cycles.

Electrical and Mechanical Equivalence: All functional parameters—voltage rating, current rating, pole configuration, connection types, and wire sizes—are identical between both parts, ensuring direct functional replacement without circuit redesign.

Series Continuity: Both parts maintain POWR-BLOKS® LS series designation, confirming design family consistency and interchangeability within existing product lines.

Frequently Asked Questions (FAQ)

Q: Can the 0LS13302Z directly replace the 0LS13002Z in existing installations?

A: Yes. Both parts are electrically and mechanically equivalent with identical voltage (600 V), current (115 A), pole configuration (2 poles), connection types (screw), and wire sizes (#14 CU/AL). Direct substitution is valid without circuit modification.

Q: What is the primary reason to transition from 0LS13002Z to 0LS13302Z?

A: The 0LS13002Z is obsolete with limited remaining inventory. The 0LS13302Z is an active product with improved RoHS3 compliance and REACH unaffected status, ensuring long-term availability and regulatory alignment.

Q: Are there packaging differences between these parts?

A: The 0LS13002Z packaging is not specified in available documentation. The 0LS13302Z is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Do both parts have the same environmental ratings?

A: Yes. Both parts share MSL rating of 1 (Unlimited), indicating identical moisture sensitivity and environmental performance characteristics.

Q: What are the key parameters that determine substitution validity?

A: Substitution is valid when the following parameters match: voltage rating (600 V), current rating (115 A), number of poles (2), connection types (screw on both sides), wire/stud sizes (#14 CU/AL), and connections per pole (1 line / 1 load). All parameters are identical between the 0LS13002Z and 0LS13302Z.
