Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Littelfuse 880065 is determined by strict equivalence across the following critical parameters:

• Current Rating: 100 A (exact match required)
• Voltage Rating: 32V (exact match required)
• Number of Circuits: 6 (exact match required)
• Fuse Type: Blade (ATC/ATO compatibility required)
• Mounting Type: Chassis Mount (exact match required)
• Orientation: Vertical (exact match required)
• Termination Style: Screw Terminal (exact match required)
• Fuseholder Type: Block (exact match required)

The Littelfuse 880027 meets all substitution criteria and is classified as an active product, providing a direct functional replacement for the obsolete 880065.

Parameter Comparison

Engineering Selection Recommendations

The Littelfuse 880027 is the recommended substitute for the obsolete 880065. Both components share identical electrical ratings (100 A, 32V), mechanical configuration (6-circuit vertical chassis mount), and termination methodology (screw terminal). The 880027 is actively manufactured and supported by Littelfuse Inc., ensuring long-term availability and supply chain continuity. Selection of the 880027 eliminates obsolescence risk while maintaining full functional compatibility with existing system designs.

Frequently Asked Questions (FAQ)

Q: Can the 880027 be used as a direct replacement for the 880065?

A: Yes. Both components are rated for 100 A at 32V, accommodate 6 ATO/ATC blade fuses, feature vertical chassis mount orientation, and utilize screw terminal connections. The 880027 is the active equivalent.

Q: What is the primary difference between these two parts?

A: The 880065 is obsolete and no longer manufactured. The 880027 is the active production equivalent from Littelfuse Inc., designated within the ST ATO® series.

Q: Are there any mechanical or electrical incompatibilities between the 880065 and 880027?

A: No incompatibilities exist. Both components meet identical specifications for current rating, voltage, circuit count, mounting configuration, and termination style.

Q: What fuse types are compatible with these blocks?

A: Both the 880065 and 880027 are designed for ATC and ATO blade fuses. The 880027 specification explicitly references ATO compatibility.

Q: Is inventory availability a consideration for component selection?

A: Yes. The 880027 is actively manufactured and supported, ensuring reliable procurement. The 880065, being obsolete, has limited remaining inventory and no future production.
