Littelfuse 0307014.M Glass Cartridge Fuse 14A 32VAC Equivalent & Substitute Parts

Part Overview

The Littelfuse 0307014.M is a 14 A, 32 V AC/DC fast-blow glass cartridge fuse in the SFE series, designed for applications requiring non-standard cartridge holder mounting. This part is classified as obsolete, making identification of active equivalent and substitute parts essential for ongoing procurement and system maintenance. Substitute parts must maintain identical electrical ratings, mechanical dimensions, and functional characteristics to ensure direct interchangeability without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0307014.M is determined by strict equivalence across the following critical parameters:

• Current Rating: 14 A (exact match required)
• Voltage Rating (AC): 32 V (exact match required)
• Response Time: Fast Blow (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Mounting Type: Requires Holder (exact match required)
• Package / Case: Cartridge, Non-Standard (exact match required)
• Size / Dimension: 0.250" Dia x 1.063" L (exact match required)
• Series: SFE (exact match required)

Two substitute parts meet these criteria and are classified as direct equivalents:

1. 0SFE014.V — Direct manufacturer equivalent with active product status and DC voltage rating specification
2. 0307014.H — Parametric equivalent with active product status and UL approval agency certification

Both substitutes maintain identical electrical and mechanical specifications while offering improved compliance and availability compared to the obsolete main part.

Parameter Comparison

Engineering Selection Recommendations

0SFE014.V is recommended for applications where RoHS3 compliance and DC voltage rating specification are required. This part carries active product status and offers the highest current inventory availability at 1,102 pieces. The explicit DC voltage rating of 32 V provides additional clarity for dual-voltage circuit applications.

0307014.H is recommended for applications requiring UL approval agency certification alongside RoHS3 compliance. This part maintains active product status with 821 pieces in inventory and provides the same electrical and mechanical specifications as the main part while offering improved regulatory compliance.

Both substitutes are electrically and mechanically interchangeable with the 0307014.M. Selection between them depends on specific compliance requirements and approval certifications mandated by the end application.

Frequently Asked Questions (FAQ)

Q: Can 0SFE014.V and 0307014.H be used interchangeably with 0307014.M?

A: Yes. Both substitute parts maintain identical current rating (14 A), voltage rating (32 V AC), response time (fast blow), fuse type (cartridge glass), mounting configuration (requires holder), and physical dimensions (0.250" Dia x 1.063" L). Direct substitution is electrically and mechanically valid.

Q: What is the difference between 0SFE014.V and 0307014.H?

A: Both parts are parametrically equivalent. The primary differences are: 0307014.H carries UL approval agency certification while 0SFE014.V does not specify an approval agency; 0SFE014.V has higher inventory availability (1,102 vs. 821 pieces). Both are RoHS3 compliant and carry active product status.

Q: Why is the main part 0307014.M classified as obsolete?

A: The 0307014.M is obsolete but remains in stock (833 pieces). Active equivalent parts 0SFE014.V and 0307014.H are preferred for new designs and ongoing procurement due to improved compliance certifications and active manufacturer support.

Q: Are there any resistance differences between the substitute parts?

A: The main part 0307014.M specifies DC cold resistance of 2.25 Ohms. The substitute part 0307014.H specifies 0.0055 Ohms. The substitute part 0SFE014.V does not specify DC cold resistance. Verify resistance requirements for your specific application before selection.

Q: What packaging options are available?

A: The main part 0307014.M is supplied in standard packaging. Both substitute parts 0SFE014.V and 0307014.H are supplied in bulk packaging, suitable for high-volume procurement and assembly operations.

Q: Are these parts RoHS compliant?

A: The main part 0307014.M is RoHS non-compliant. Both substitute parts 0SFE014.V and 0307014.H are ROHS3 compliant, meeting current environmental and regulatory standards for electronic component manufacturing.
