Equivalent & Substitute Parts for 0JTD080.V

Part Overview

The 0JTD080.V is an 80A cartridge fuse rated for 600 VAC and 300 VDC operation, manufactured by Littelfuse Inc. under the POWR-GARD® and POWR-PRO® JTD series. This slow-blow Class J fuse is designed for transformer protection applications and requires a separate holder for installation. The part is currently active in production with full compliance to CE, CSA, and UL standards. Equivalent substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when system design requires different mounting configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0JTD080.V is determined by the following critical parameters:

• Current Rating: 80A (exact match required)
• Voltage Rating: 600 VAC / 300 VDC (exact match required)
• Fuse Type: Cartridge (exact match required)
• Response Time: Slow Blow (exact match required)
• Class: J (exact match required)
• Approval Agencies: CE, CSA, UL certification (all three required)
• RoHS Compliance: ROHS3 Compliant (required)

The LPJ-80SP meets all substitution criteria. While mounting configuration differs (bolt mount versus holder requirement), both parts are Class J cartridge fuses with identical electrical ratings and certifications. Physical dimensions are equivalent within manufacturing tolerances.

Parameter Comparison

Engineering Selection Recommendations

Both the 0JTD080.V and LPJ-80SP are active production parts with full CE, CSA, and UL certification. Selection between these parts should be based on system mounting requirements and available holder or bolt-mount infrastructure. The 0JTD080.V requires a separate fuse holder, while the LPJ-80SP features bolt-mount terminals for direct installation. Both parts maintain ROHS3 compliance and are suitable for transformer protection applications at the specified electrical ratings.

Frequently Asked Questions (FAQ)

Q: Can the LPJ-80SP replace the 0JTD080.V in all applications?

A: Both parts meet identical electrical specifications (80A, 600 VAC, 300 VDC, Class J, slow-blow response). The primary difference is mounting configuration. The 0JTD080.V requires a holder assembly, while the LPJ-80SP uses bolt-mount terminals. Substitution is valid when the system design accommodates the mounting method of the replacement part.

Q: Are the physical dimensions interchangeable?

A: Dimensions are equivalent within manufacturing tolerances. The 0JTD080.V measures 1.126" Dia x 2.626" L, and the LPJ-80SP measures 1.130" Dia x 2.630" L. These minor variations do not affect holder or mount compatibility.

Q: Do both parts carry the same certifications?

A: Yes. Both the 0JTD080.V and LPJ-80SP are certified by CE, CSA, and UL, meeting the same regulatory standards for transformer protection applications.

Q: What is the difference in breaking capacity?

A: The 0JTD080.V has a breaking capacity of 200kA AC and 20kA DC. The LPJ-80SP has a breaking capacity of 300kA AC and 100kA DC. Both exceed the minimum requirements for Class J fuses at the specified voltage ratings.

Q: Are both parts RoHS compliant?

A: Yes. Both the 0JTD080.V and LPJ-80SP are ROHS3 compliant and REACH unaffected.
