Key Parameters

Substitute Part Grouping Explanation

Substitution of the Parallax Inc. 452-00065 is determined by the following critical parameters:

Current Rating: Both the main part and substitute maintain 2 A current rating, ensuring equivalent load protection characteristics.

Fuse Type: Both are classified as automotive fuses, meeting the same application requirements.

Package / Case: Both utilize Blade, Miniature (Low Profile) form factor, ensuring mechanical compatibility with existing fuse holders.

Mounting Type: Both require a holder, maintaining the same installation methodology.

Operating Temperature Range: The main part operates -40°C to 85°C. The substitute (Littelfuse 0891002.NXS) operates -40°C to 125°C, providing extended thermal capability within the original operating envelope.

The Littelfuse 0891002.NXS is an active product with current manufacturing status, addressing the obsolescence of the original Parallax component.

Parameter Comparison

Engineering Selection Recommendations

The Littelfuse Inc. 0891002.NXS serves as the direct substitute for the obsolete Parallax 452-00065 based on the following engineering criteria:

Functional Equivalence: Both components share identical current rating (2 A), fuse type (automotive), and mechanical package (blade, miniature low profile), ensuring drop-in compatibility within existing fuse holder assemblies.

Product Status: The Littelfuse component maintains active manufacturing status, providing assured long-term availability and supply chain continuity compared to the obsolete Parallax part.

Compliance and Certification: The Littelfuse 0891002.NXS is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for automotive component procurement.

Thermal Performance: The extended operating temperature range (-40°C to 125°C) of the Littelfuse substitute encompasses the original specification (-40°C to 85°C), providing thermal margin for system applications.

Electrical Specifications: The substitute provides defined DC voltage rating (58 V) and breaking capacity (1 kA), offering documented electrical performance characteristics absent from the original part specification.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 0891002.NXS directly replace the Parallax 452-00065 in existing assemblies?

A: Yes. Both components share identical current rating (2 A), automotive fuse type classification, and blade miniature (low profile) package form factor. The substitute is mechanically and functionally compatible with existing fuse holder installations.

Q: What is the significance of the "Fast Blow" response time specification on the Littelfuse part?

A: Fast Blow indicates the fuse operates with rapid response to overcurrent conditions. This specification is provided for the Littelfuse component but not documented for the original Parallax part. Verify system circuit design compatibility with fast-blow fuse characteristics.

Q: Does the extended operating temperature range of the Littelfuse part affect compatibility?

A: No. The Littelfuse operating range (-40°C to 125°C) fully encompasses the original specification (-40°C to 85°C). Extended thermal capability does not compromise compatibility and provides additional margin for system applications.

Q: Are there packaging differences between the two components?

A: Both components utilize identical blade miniature (low profile) packaging. The Littelfuse part is supplied in bulk packaging, while original packaging information for the Parallax component is not specified. Packaging format does not affect functional compatibility.

Q: What compliance certifications apply to the substitute part?

A: The Littelfuse 0891002.NXS is ROHS3 compliant and REACH unaffected, meeting current automotive and electronics industry regulatory requirements.
