Littelfuse 0307020.H Glass Cartridge Fuse 20A 32VAC/VDC Equivalent & Substitute Parts

Part Overview

The Littelfuse 0307020.H is a fast-blow glass cartridge fuse rated for 20 amperes at 32 volts AC/DC. This fuse is designed for use in 3AB and 3AG holder configurations with a 1/4" x 1-1/4" form factor. The part is currently active in production with 1119 units in stock. Equivalent and substitute parts are identified based on matching electrical ratings, mechanical dimensions, and holder compatibility to ensure direct interchangeability in circuit protection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0307020.H is determined by the following critical parameters:

• Current Rating: 20 A (exact match required)
• Voltage Rating: 32 V AC and 32 V DC (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Mounting Type: Requires Holder (exact match required)

All substitute parts listed below meet these electrical and mechanical requirements and are therefore directly interchangeable with the main part in applications requiring a 20A 32V glass cartridge fuse with 3AB/3AG holder compatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with confirmed availability. Selection among equivalent parts should be based on the following criteria:

ROHS3 Compliance: Parts 0AGC020.V, 0AGC020.VP, 0SFE020.V, and 0SFE020.VP are ROHS3 compliant, matching the compliance status of the main part 0307020.H. The Eaton part BK/SFE-20 is RoHS non-compliant and should be selected only when RoHS compliance is not a requirement.

Series Consistency: The SFE series parts (0307020.H, 0SFE020.V, 0SFE020.VP, and BK/SFE-20) share the same series designation. The AGC series parts (0AGC020.V, 0AGC020.VP) represent an alternative series with identical electrical and mechanical specifications.

Response Time: The main part 0307020.H and parts 0SFE020.V and BK/SFE-20 are specified as fast-blow fuses. Parts 0AGC020.V, 0AGC020.VP, and 0SFE020.VP do not specify response time in the provided data.

Packaging: Parts designated with ".VP" suffix indicate 5-pack card packaging, while ".V" and ".H" designations indicate bulk packaging. Packaging selection depends on procurement and inventory requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute 0AGC020.V for 0307020.H?

A: Yes. Both parts share identical electrical ratings (20A, 32V AC/DC), fuse type (cartridge glass), and mechanical dimensions (0.250" Dia x 1.250" L). Both are compatible with 3AB and 3AG holders and are ROHS3 compliant. The primary difference is the series designation (AGC versus SFE).

Q: What is the difference between parts ending in ".V" and ".VP"?

A: The ".VP" designation indicates 5-pack card packaging, while ".V" indicates bulk packaging. Electrical and mechanical specifications are identical between these variants.

Q: Is the Eaton BK/SFE-20 a direct substitute?

A: The Eaton BK/SFE-20 meets all electrical and mechanical requirements for interchangeability. However, it is RoHS non-compliant, whereas the main part 0307020.H is ROHS3 compliant. Selection should account for compliance requirements in the target application.

Q: Do all substitute parts fit the same holder?

A: Yes. All parts listed are designed for 3AB and 3AG holder configurations with identical 1/4" x 1-1/4" form factors and are mechanically interchangeable.

Q: What is the significance of "fast blow" versus unspecified response time?

A: Fast-blow fuses (0307020.H, 0SFE020.V, BK/SFE-20) respond quickly to overcurrent conditions. Parts with unspecified response time (0AGC020.V, 0AGC020.VP, 0SFE020.VP) may have different response characteristics. Application requirements should determine whether response time specification is critical.
