Littelfuse 0307006.M Glass Cartridge Fuse Equivalent & Substitute Parts

Part Overview

The Littelfuse 0307006.M is a 6 A, 32 V AC DC glass cartridge fuse with fast-blow response characteristics. This component is classified as obsolete, necessitating identification of active equivalent parts for continued system support and procurement. The fuse requires a dedicated holder for installation and operates within non-standard cartridge dimensions of 0.250" diameter by 0.750" length.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0307006.M is determined by the following critical parameters:

• Current Rating: 6 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)
• Series: SFE (same product family)
• Size / Dimension: 0.250" Dia x 0.750" L or equivalent non-standard cartridge dimensions

The following parts meet these substitution criteria and are available as active alternatives:

1. 0307006.H — Parametric equivalent with identical electrical and mechanical specifications, UL approved, RoHS3 compliant
2. 0SFE006.V — Direct manufacturer equivalent with identical electrical specifications, RoHS3 compliant, minor dimensional variation (0.748" L vs 0.750" L)

Parameter Comparison

Engineering Selection Recommendations

0307006.H is the primary recommended substitute. This part maintains identical electrical and mechanical specifications to the main part, including exact dimensional match (0.250" Dia x 0.750" L), UL approval certification, and RoHS3 compliance. The part is currently in active production status with 997 units in stock.

0SFE006.V serves as a secondary alternative. While electrically equivalent with explicit 32 V DC rating and RoHS3 compliance, this part exhibits a minor dimensional variation of 0.002" in length (0.748" L vs 0.750" L). This dimensional difference may require verification for mechanical fit within existing fuse holder assemblies. The part is active with 840 units in stock.

Both substitutes eliminate the RoHS non-compliance status of the obsolete main part and provide active product support from the manufacturer.

Frequently Asked Questions (FAQ)

Q: Can 0307006.H and 0SFE006.V be used interchangeably with 0307006.M?

A: Both parts meet the electrical substitution criteria (6 A, 32 V AC, Fast Blow, Cartridge Glass). 0307006.H maintains exact dimensional specifications. 0SFE006.V has a 0.002" length variation that requires mechanical fit verification with the existing fuse holder.

Q: What is the significance of the DC voltage rating difference?

A: The main part 0307006.M does not specify a DC voltage rating, while both substitutes explicitly rate 32 V DC. This explicit rating in the substitutes provides additional operational clarity for DC circuit applications.

Q: Are there RoHS compliance implications for substitution?

A: The main part is RoHS non-compliant. Both active substitutes are ROHS3 compliant, providing improved environmental and regulatory alignment for new procurement and system updates.

Q: Does the packaging format affect electrical performance?

A: No. Both substitutes are supplied in bulk packaging. Packaging format does not affect fuse electrical characteristics or performance.

Q: What holder compatibility should be verified?

A: The fuse holder must accommodate the non-standard cartridge dimensions. For 0307006.H, the exact dimensional match (0.250" Dia x 0.750" L) ensures compatibility with holders designed for the main part. For 0SFE006.V, the 0.002" length difference should be verified against holder specifications before deployment.
