Littelfuse 0362020.M Glass Cartridge Fuse 20A 32V Equivalent & Substitute Parts

Part Overview

The Littelfuse 0362020.M is a 20A 32VAC/32VDC glass cartridge fuse in the 8AG form factor (1/4" x 1"). This component is classified as obsolete, making identification of suitable substitutes necessary for ongoing maintenance and repair applications. The fuse requires a compatible holder for installation and operates with fast-blow response characteristics. Equivalent parts maintain identical electrical ratings and mechanical dimensions to ensure direct functional replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 0362020.M is determined by strict equivalence across the following parameters: current rating (20A), voltage ratings (32VAC/32VDC), fuse type (cartridge glass), package designation (8AG), and physical dimensions (0.250" Dia x 1.000" L). All identified substitutes maintain these specifications, ensuring mechanical and electrical compatibility within the original circuit design.

The substitute parts are grouped into two categories:

Parametric Equivalents (Littelfuse AGX Series): Parts 0AGX020.V and 0AGX020.VP are direct electrical and mechanical equivalents manufactured by Littelfuse. These maintain identical 20A 32V ratings and 8AG form factor.

Manufacturer Recommended Equivalent (Eaton BK/AGX-20): This part shares the same current rating, fuse type, package, and physical dimensions. However, it operates at a higher voltage rating (250VAC) and includes additional certifications (cURus approval, 200A breaking capacity). This part is suitable only in applications where the higher voltage rating does not create circuit incompatibility.

Engineering Selection Recommendations

Primary Selection: 0AGX020.VP

This part is the preferred substitute. It maintains exact electrical equivalence (20A 32VAC/32VDC), identical mechanical form factor (8AG, 0.250" Dia x 1.000" L), and is currently in active production status. The part achieves ROHS3 compliance and is available in bulk packaging. Current inventory supports immediate procurement.

Secondary Selection: 0AGX020.V

This part provides identical electrical and mechanical specifications to the main part. However, it is discontinued at DiGi Electronics, limiting long-term availability. Use only when 0AGX020.VP is unavailable.

Alternative Selection: BK/AGX-20 (Eaton)

This part is suitable only in applications where circuit voltage ratings permit operation at 250VAC. The physical dimension variance (0.250" Dia x 1.042" L versus 0.250" Dia x 1.000" L) requires confirmation of holder compatibility. The part includes cURus certification and 200A breaking capacity. Use only when higher voltage rating and certifications are compatible with circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can 0AGX020.VP be used as a direct replacement for 0362020.M?

A: Yes. Both parts share identical current rating (20A), voltage ratings (32VAC/32VDC), fuse type (cartridge glass), package designation (8AG), and physical dimensions (0.250" Dia x 1.000" L). Mechanical and electrical compatibility is confirmed.

Q: What is the difference between 0AGX020.V and 0AGX020.VP?

A: Both parts are electrically and mechanically identical. The primary difference is packaging: 0AGX020.V is supplied individually, while 0AGX020.VP is supplied in bulk (5-pack card). 0AGX020.VP is currently active in production; 0AGX020.V is discontinued at DiGi Electronics.

Q: Can BK/AGX-20 (Eaton) be used in place of 0362020.M?

A: BK/AGX-20 is mechanically compatible (8AG form factor, 20A current rating) but operates at 250VAC, which exceeds the original 32VAC specification. Use only if circuit design permits higher voltage rating. Physical dimension variance (length 1.042" versus 1.000") requires holder compatibility confirmation.

Q: What does "Requires Holder" mean?

A: All listed parts are cartridge fuses that must be installed in a compatible fuse holder. The holder provides electrical contact and mechanical retention. Ensure the holder is rated for 8AG cartridge fuses and 32V operation (or higher for BK/AGX-20).

Q: Are there RoHS compliance considerations?

A: The original 0362020.M is RoHS non-compliant. Substitute 0AGX020.VP achieves ROHS3 compliance. If RoHS compliance is required for your application, select 0AGX020.VP. Other substitutes (0AGX020.V and BK/AGX-20) are RoHS non-compliant.
