Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete Littelfuse 0897003.N is determined by strict equivalence across the following critical parameters:

• Current Rating: 3 A (exact match required)
• Voltage Rating: 58 V DC (exact match required)
• Response Characteristic: Fast Blow (exact match required)
• Package Form Factor: Blade, Miniature configuration (exact match required)
• Breaking Capacity: 1 kA @ Rated Voltage (exact match required)
• Operating Temperature: -40°C to 125°C (exact match required)
• Mounting Interface: Requires Holder (exact match required)

The Littelfuse 0997003.WXN meets all substitution criteria as an active product within the MINI® 997 series, providing direct functional and mechanical compatibility with the obsolete 0897003.N.

Parameter Comparison

Engineering Selection Recommendations

The Littelfuse 0997003.WXN is the direct equivalent substitute for the obsolete 0897003.N. Selection is based on:

• Identical electrical ratings across current, voltage, and response characteristics
• Mechanical compatibility with existing blade fuse holders
• Full ROHS3 compliance and REACH unaffected status
• Identical operating temperature range and breaking capacity specifications
• Dimensional compatibility within miniature blade fuse form factor standards

The 0997003.WXN represents the manufacturer-recommended upgrade path for applications currently using the obsolete 0897003.N.

Frequently Asked Questions (FAQ)

Q: Can the 0997003.WXN be used as a direct replacement in existing designs using 0897003.N?

A: Yes. The 0997003.WXN meets all electrical and mechanical specifications of the 0897003.N, including current rating, voltage rating, response time, breaking capacity, and operating temperature range. Physical dimensions are compatible with standard miniature blade fuse holders.

Q: What is the difference between the "Blade, Miniature (Low Profile)" and "Blade, Miniature" package designations?

A: Both designations refer to miniature blade fuse form factors. The dimensional data shows the 0997003.WXN height is 8.80mm compared to 0897003.N at 8.73mm, representing a negligible 0.07mm difference within standard holder tolerances.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant. The 0997003.WXN includes additional REACH unaffected status documentation. No approval agency certifications are specified for either part.

Q: Why is the 0897003.N classified as obsolete?

A: The 0897003.N belongs to the MINI® 897 series, which has been superseded by the MINI® 997 series. The 0997003.WXN represents the current production equivalent within the active product line.

Q: What additional technical data is provided for the 0997003.WXN?

A: The 0997003.WXN includes melting I²t value of 9.4 and DC cold resistance of 0.03375 Ohms. These parameters provide additional thermal and electrical characterization for detailed circuit analysis if required.
