Littelfuse 0326.600MXP Ceramic Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0326.600MXP is a 600 mA ceramic cartridge fuse rated for 250 V AC and 125 V DC operation. This slow-blow fuse is designed for applications requiring holder-based mounting in 3AB, 3AG, or 1/4" x 1-1/4" form factors. The part maintains active product status with full compliance to ROHS3, CE, CSA, and UL standards. Substitute parts are identified when electrical ratings, mechanical dimensions, and approval certifications align with the original specification.

Substitute Part Grouping Explanation

Substitute parts for the 0326.600MXP are qualified based on the following critical parameters:

  • Current Rating: 600 mA (exact match required)
  • Voltage Rating - AC: 250 V (exact match required)
  • Fuse Type: Cartridge, Ceramic (exact match required)
  • Response Time: Slow Blow (exact match required)
  • Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
  • Size / Dimension: 0.250" Dia x 1.250" L (exact match required)
  • Mounting Type: Requires Holder (exact match required)

Two substitute parts meet these criteria: the Littelfuse 0326.600HXP (parametric equivalent) and the Eaton BK/MDA-6/10-R (manufacturer-recommended equivalent).

Engineering Selection Recommendations

The Littelfuse 0326.600HXP serves as a direct parametric equivalent to the 0326.600MXP. Both parts are manufactured by Littelfuse Inc., maintain identical electrical and mechanical specifications, and carry the same compliance certifications (CE, CSA, UL). Selection between these two Littelfuse variants depends on inventory availability and application-specific requirements.

The Eaton BK/MDA-6/10-R is a manufacturer-recommended alternative that matches the primary electrical and mechanical parameters. This part carries ROHS3 compliance and maintains the same current rating, AC voltage rating, fuse type, response time, and physical dimensions. The DC voltage rating is not specified for the Eaton part. The DC cold resistance differs at 0.78 Ohms compared to 0.9495 Ohms for the Littelfuse variants. Operating temperature range is not specified for the Eaton part.

All three parts are active products with current availability.

Frequently Asked Questions (FAQ)

Q: Can the 0326.600HXP replace the 0326.600MXP in all applications?

A: Yes. The 0326.600HXP is a parametric equivalent with identical current rating, voltage ratings, fuse type, response time, package form factor, and physical dimensions. Both parts carry the same compliance certifications.

Q: What are the key differences between the Littelfuse and Eaton substitutes?

A: The Littelfuse 0326.600HXP is a direct parametric match. The Eaton BK/MDA-6/10-R matches the primary electrical and mechanical specifications but has a lower DC cold resistance (0.78 Ohms vs. 0.9495 Ohms) and does not specify DC voltage rating or operating temperature range.

Q: Are all three parts compatible with the same holder?

A: Yes. All three parts use the 3AB, 3AG, 1/4" x 1-1/4" package form factor and require holder-based mounting. Physical dimensions are identical at 0.250" Dia x 1.250" L.

Q: What compliance certifications apply to these parts?

A: The Littelfuse 0326.600MXP and 0326.600HXP carry CE, CSA, and UL approvals. The Eaton BK/MDA-6/10-R does not specify approval agencies. All three parts are ROHS3 compliant.

Q: Does DC voltage rating matter when selecting a substitute?

A: The 0326.600MXP and 0326.600HXP both specify 125 V DC rating. The Eaton BK/MDA-6/10-R does not specify a DC voltage rating. For applications requiring DC operation, the Littelfuse variants provide explicit DC rating specification.
