Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Littelfuse 0287002.H is determined by strict equivalence across the following critical parameters:

• Current Rating: 2 A (exact match required)
• Voltage Rating (DC): 32 V (exact match required)
• Package / Case: Blade, ATO/ATC (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 1 kA (exact match required)
• Melting I²t: 1.4 (exact match required)
• Series: ATOF® (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match required)
• DC Cold Resistance: 0.0535 Ohms (exact match required)

Only parts meeting all these criteria qualify as direct parametric equivalents. Packaging format (Bulk) does not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The Littelfuse 0287002.PXCN is a direct parametric equivalent to the 0287002.H. Both parts are manufactured by Littelfuse Inc., carry Active product status, maintain UL approval, and comply with ROHS3 requirements. All electrical characteristics, mechanical dimensions, and thermal specifications are identical. Selection between these parts may be based on packaging availability and inventory considerations, as both are suitable for identical circuit applications without modification to existing fuse holders or circuit designs.

Frequently Asked Questions (FAQ)

Q: Can 0287002.PXCN be used as a direct replacement for 0287002.H?

A: Yes. Both parts are parametric equivalents with identical current ratings (2A), voltage ratings (32VDC), package types (Blade, ATO/ATC), response characteristics (Fast Blow), and all other electrical and mechanical specifications. No circuit modification is required.

Q: What determines if a fuse is a valid substitute?

A: Valid substitutes must match all critical parameters: current rating, voltage rating, fuse type, package configuration, response time, breaking capacity, melting I²t value, series designation, operating temperature range, and DC cold resistance. Deviation in any parameter disqualifies a part as a direct equivalent.

Q: Are there differences in holder compatibility?

A: No. Both the 0287002.H and 0287002.PXCN use the Blade, ATO/ATC package format and require the same holder type. They are mechanically interchangeable.

Q: Do compliance certifications differ between these parts?

A: No. Both parts carry identical UL approval, ROHS3 compliance, REACH Unaffected status, and ECCN/HTSUS classifications.

Q: What is the significance of the ATOF® series designation?

A: The ATOF® series designation indicates the product family and performance characteristics. Both parts belong to this series, confirming they share the same design standards and performance envelope.
