Littelfuse 0307014.H Glass Cartridge Fuse 14A 32V Equivalent & Substitute Parts

Part Overview

The Littelfuse 0307014.H is a 14 A, 32 V AC/DC glass cartridge fuse with fast-blow response characteristics. This non-standard cartridge fuse requires a compatible holder for installation and is designed for circuit protection applications requiring rapid fault response. The part maintains active product status with UL approval and ROHS3 compliance. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the Littelfuse 0307014.H is determined by strict equivalence across the following critical parameters: current rating (14 A), voltage ratings (32 V AC and 32 V DC), fuse type (cartridge glass), physical dimensions (0.250" Dia x 1.063" L), and mounting requirement (requires holder). All identified substitutes maintain these core electrical and mechanical specifications, ensuring direct functional interchangeability within the same circuit protection application.

The substitute parts are categorized as follows:

Parametric Equivalents: Parts with identical electrical ratings and physical dimensions that satisfy the same application requirements.

Manufacturer Recommended Equivalent: A cross-manufacturer part meeting the same electrical and mechanical specifications, provided by an alternative approved manufacturer.

Engineering Selection Recommendations

0SFE014.V (Littelfuse Inc.): This parametric equivalent maintains identical electrical ratings and physical dimensions to the main part. ROHS3 compliance is confirmed. Selection is appropriate for applications where RoHS compliance is required and UL certification is not mandated.

0SFE014.VP (Littelfuse Inc.): This parametric equivalent provides the same electrical and mechanical specifications as the main part with ROHS3 compliance. The packaging designation indicates a five-pack carton configuration. Selection is appropriate for high-volume procurement scenarios requiring RoHS compliance.

BK/SFE-14 (Eaton - Electronics Division): This manufacturer-recommended equivalent meets the electrical ratings and physical dimensions of the main part. UL approval is confirmed, matching the certification status of the main part. However, this part is RoHS non-compliant. Selection is appropriate for applications where RoHS compliance is not a requirement and cross-manufacturer sourcing is acceptable.

Frequently Asked Questions (FAQ)

Q: Can 0SFE014.V be used as a direct replacement for 0307014.H?

A: Yes. Both parts share identical current ratings (14 A), voltage ratings (32 V AC/DC), fuse type (cartridge glass), physical dimensions (0.250" Dia x 1.063" L), and mounting requirements. Electrical and mechanical interchangeability is confirmed.

Q: What is the difference between 0SFE014.V and 0SFE014.VP?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The primary difference is packaging: 0SFE014.VP is supplied in a five-pack carton configuration, while 0SFE014.V is supplied in bulk. Electrical performance and physical dimensions are identical.

Q: Is BK/SFE-14 suitable for RoHS-compliant applications?

A: No. BK/SFE-14 is RoHS non-compliant. For applications requiring RoHS compliance, use 0SFE014.V or 0SFE014.VP, both of which are ROHS3 compliant.

Q: Does BK/SFE-14 have UL approval?

A: Yes. BK/SFE-14 carries UL approval, matching the certification status of the main part 0307014.H. Both parts are suitable for applications requiring UL-certified components.

Q: Are all substitute parts compatible with the same fuse holder?

A: Yes. All substitute parts maintain the non-standard cartridge dimensions (0.250" Dia x 1.063" L) and require a compatible holder. Physical interchangeability is confirmed across all listed substitutes.

Q: What is the DC cold resistance specification for substitute parts?

A: DC cold resistance is specified only for the main part 0307014.H at 0.0055 Ohms. This specification is not provided for the substitute parts in the available data.
