Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0287030.H are identified based on the following critical parameters that must remain constant for direct replacement compatibility:

• Current Rating: 30 A (exact match required)
• Voltage Rating - DC: 32 V (exact match required)
• Package / Case: Blade, ATO/ATC (exact match required)
• Size / Dimension: 0.752" L x 0.201" W x 0.484" H (exact match required)
• Melting I²t: 1510 (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match required)
• Series: ATOF® (exact match required)

The identified substitutes—0287030.PXCN and 0287030.U—maintain all critical electrical and mechanical parameters, ensuring functional equivalence within automotive fuse holder applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—0287030.H, 0287030.PXCN, and 0287030.U—are Active status products manufactured by Littelfuse Inc. and maintain identical electrical and mechanical specifications for the ATOF® 30A 32V DC automotive fuse series.

The 0287030.H and 0287030.PXCN both carry CSA and UL approval certifications. The 0287030.U does not list approval agency certifications in the provided data.

All parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for automotive applications.

Selection between these equivalents should be based on availability, packaging requirements (Bulk), and certification requirements specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can 0287030.PXCN and 0287030.U be used interchangeably with 0287030.H?

A: Yes. All three parts maintain identical current rating (30A), voltage rating (32V DC), package type (Blade, ATO/ATC), physical dimensions, melting I²t value (1510), and operating temperature range (-40°C to 105°C). They are functionally equivalent for direct replacement in compatible ATO/ATC fuse holders.

Q: What is the significance of the color difference in 0287030.U?

A: The 0287030.U is available in both Blue and Green color options, while 0287030.H and 0287030.PXCN are Green only. Color coding in automotive fuses typically indicates amperage rating. All three parts are rated 30A and maintain the same electrical characteristics regardless of color variant.

Q: Are there differences in approval certifications between these parts?

A: The 0287030.H and 0287030.PXCN carry CSA and UL certifications. The 0287030.U does not list approval agency certifications in the provided specifications. Applications requiring specific certification compliance should reference the 0287030.H or 0287030.PXCN.

Q: What determines substitution eligibility for automotive fuses in this series?

A: Substitution eligibility is determined by exact matching of current rating (30A), voltage rating (32V DC), package configuration (Blade, ATO/ATC), physical dimensions (0.752" x 0.201" x 0.484"), melting I²t value (1510), and operating temperature range (-40°C to 105°C). All identified substitutes meet these criteria.

Q: Can these fuses be used in applications beyond automotive?

A: These components are classified as automotive fuses and are designed for automotive electrical protection applications. Use in non-automotive applications should be evaluated against specific circuit requirements and applicable standards.
