Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Littelfuse 028707.5U are determined by strict equivalence across the following critical parameters:

• Current Rating: 7.5 A
• Voltage Rating - DC: 32 V
• Package / Case: Blade, ATO/ATC
• Melting I²t: 60
• Operating Temperature Range: -40°C ~ 105°C
• Physical Dimensions: 0.752" L x 0.201" W x 0.484" H
• RoHS3 Compliance

All identified substitutes maintain identical electrical performance characteristics and physical form factor, ensuring direct compatibility within automotive fuse holder assemblies. Substitution is based solely on parametric equivalence; no functional or performance differences exist between the main part and substitute options.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—028707.5U, 028707.5H, and 028707.5PXCN—are functionally equivalent and maintain Active product status. Selection between these substitutes may be based on availability and inventory levels:

• 028707.5PXCN: 48,300 pcs in stock
• 028707.5U: 1,371 pcs in stock
• 028707.5H: 1,039 pcs in stock

All parts carry ROHS3 compliance and REACH unaffected classification, meeting regulatory requirements for automotive applications. Approval agencies listed for 028707.5H and 028707.5PXCN include CSA and UL certifications. Direct substitution is permissible without circuit redesign or holder modification.

Frequently Asked Questions (FAQ)

Q: Can 028707.5H be used as a direct replacement for 028707.5U?

A: Yes. Both parts share identical current rating (7.5 A), voltage rating (32 V DC), package format (Blade, ATO/ATC), melting I²t (60), operating temperature range (-40°C ~ 105°C), and physical dimensions. Direct substitution is permissible.

Q: Are there any differences in breaking capacity between the substitute parts?

A: The main part 028707.5U specifies 1 kA breaking capacity at rated voltage. Breaking capacity data is not provided for 028707.5H and 028707.5PXCN in the available specifications. Substitution remains valid based on all other parametric equivalence.

Q: Do all substitute parts fit the same fuse holder?

A: Yes. All three parts use the Blade, ATO/ATC package format with identical physical dimensions (0.752" L x 0.201" W x 0.484" H). No holder modification is required for substitution.

Q: What is the significance of the color coding?

A: All three parts are brown, which corresponds to the 7.5 A current rating in automotive fuse color standards. Color consistency confirms parametric equivalence.

Q: Are there compliance differences between the substitute parts?

A: All three parts are ROHS3 compliant and REACH unaffected. Parts 028707.5H and 028707.5PXCN carry CSA and UL approvals. All parts meet automotive regulatory requirements.
