Littelfuse 0891030.H Automotive Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0891030.H is a 30A automotive blade fuse rated for 58V DC operation with fast-blow response characteristics. This miniature low-profile fuse is designed for automotive electrical circuit protection and requires a compatible fuse holder for installation. The part is currently in active production status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified to provide alternative sourcing options while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0891030.H are identified based on strict parametric equivalence. All substitute parts must match the following critical parameters:

• Current Rating: 30 A
• Voltage Rating (DC): 58 V
• Response Time: Fast Blow
• Package Type: Blade, Miniature (Low Profile)
• Breaking Capacity: 1 kA @ Rated Voltage
• DC Cold Resistance: 0.00206 Ohms
• Melting I²t: 1110
• Operating Temperature Range: -40°C to 125°C
• Physical Dimensions: 10.90mm L × 3.80mm W × 8.40mm H
• RoHS Status: ROHS3 Compliant

All identified substitutes meet these parameters without exception and belong to the Littelfuse LP MINI® 891 series.

Frequently Asked Questions (FAQ)

Q: Are 0891030.H, 0891030.NXS, and 0891030.U fully interchangeable?

A: Yes. All three parts are parametric equivalents with identical electrical characteristics, mechanical dimensions, response time, and thermal ratings. They are direct substitutes for one another in automotive fuse applications.

Q: What determines if a fuse can substitute for the 0891030.H?

A: A substitute fuse must match all critical parameters: 30A current rating, 58V DC voltage rating, fast-blow response, 1kA breaking capacity, 0.00206 Ohms DC cold resistance, 1110 melting I²t value, miniature low-profile blade package, and -40°C to 125°C operating temperature range.

Q: Do these fuses require a specific holder type?

A: Yes. All three parts require a compatible automotive fuse holder designed for miniature low-profile blade fuses. The physical dimensions (10.90mm L × 3.80mm W × 8.40mm H) must match the holder specifications.

Q: Are there any compliance differences between these part numbers?

A: No. All three parts carry identical RoHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can these fuses be used in applications rated for different voltage levels?

A: No. These fuses are rated for 58V DC operation. Use only in circuits where the maximum voltage does not exceed the rated specification.
