Littelfuse 0324006.MXP Ceramic Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0324006.MXP is a 6 A ceramic cartridge fuse rated for 250 V AC and 125 V DC operation. This through-hole mounted component is designed for fast-blow response applications requiring reliable overcurrent protection in industrial and commercial equipment. The part maintains active product status with full compliance to international safety standards including CE, CSA, K-MARK, PSE, and UL certifications. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across alternative manufacturer offerings.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0324006.MXP are qualified based on the following critical parameters that must remain constant:

• Current Rating: 6 A (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Voltage Rating - DC: 125 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial) (mechanical compatibility required)
• Mounting Type: Through Hole (exact match required)
• RoHS Status: ROHS3 Compliant (regulatory compliance required)

Two substitute parts meet these criteria: the Littelfuse 0324006.HXP (parametric equivalent from the same manufacturer and series) and the Eaton GBB-V-6-R (manufacturer-recommended alternative with equivalent electrical ratings).

Parameter Comparison

Engineering Selection Recommendations

The 0324006.HXP serves as a direct parametric equivalent within the Littelfuse 324 series, maintaining identical electrical ratings, breaking capacity, melting I²t characteristics, and approval certifications. This substitute is suitable for applications where Littelfuse product continuity is preferred or specified.

The Eaton GBB-V-6-R provides an alternative from a different manufacturer with equivalent core electrical parameters (6 A, 250 V AC, 125 V DC, fast-blow ceramic cartridge). However, the GBB-V-6-R exhibits a lower breaking capacity at rated AC voltage (200A versus 750A) and carries a reduced certification scope (CSA, UR versus CE, CSA, K-MARK, PSE, UL). Selection of the Eaton substitute should be confirmed against specific application requirements and regional compliance mandates.

Both substitutes maintain ROHS3 compliance and active product status, ensuring continued availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the 0324006.HXP be used as a direct replacement for the 0324006.MXP?

A: Yes. The 0324006.HXP is a parametric equivalent with identical current rating (6 A), voltage ratings (250 V AC, 125 V DC), fuse type (ceramic cartridge), response time (fast-blow), package dimensions (3AB, 3AG, 1/4" x 1-1/4"), and approval certifications. Both parts are from Littelfuse and maintain the same electrical performance characteristics.

Q: What are the key differences between the Littelfuse 0324006.MXP and the Eaton GBB-V-6-R?

A: Both parts share identical current and voltage ratings, fuse type, response time, and package form factor. The primary differences are: (1) Breaking capacity at rated AC voltage is 750A for the Littelfuse versus 200A for the Eaton; (2) Approval certifications differ, with Littelfuse holding CE, CSA, K-MARK, PSE, and UL versus Eaton holding CSA and UR; (3) DC cold resistance is 0.024 Ohms for Littelfuse versus 0.018 Ohms for Eaton; (4) Physical dimensions vary slightly (0.275" Dia x 1.288" L for Littelfuse versus 0.266" Dia x 1.292" L for Eaton).

Q: Are there mechanical compatibility concerns when substituting the Eaton GBB-V-6-R?

A: The Eaton GBB-V-6-R maintains the same 3AB, 3AG package designation and 1/4" x 1-1/4" axial form factor. Minor dimensional variations (0.266" Dia x 1.292" L versus 0.275" Dia x 1.288" L) are within typical manufacturing tolerances for this package class and should not create mechanical interference in standard through-hole fuse holders.

Q: Which substitute should be selected for applications requiring maximum breaking capacity?

A: The Littelfuse 0324006.HXP maintains the same 750A AC breaking capacity as the 0324006.MXP. The Eaton GBB-V-6-R is rated for 200A AC breaking capacity and should be selected only when application requirements align with this lower specification.

Q: Are all three parts RoHS compliant?

A: Yes. The 0324006.MXP, 0324006.HXP, and GBB-V-6-R are all ROHS3 compliant.
