Littelfuse 0326020.MXCCP Ceramic Cartridge Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0326020.MXCCP is a 20 A 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 CE, CSA, KC, PSE, and UL standards. Equivalent and substitute parts are identified based on matching electrical ratings, mechanical dimensions, response characteristics, and approval certifications to ensure direct functional interchangeability in circuit protection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0326020.MXCCP is determined by the following critical parameters:

• Current Rating: 20 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: Slow Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Physical Dimensions: 0.250" Dia x 1.250" L (exact match required)
• Mounting Type: Requires Holder (exact match required)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the main part number.

Parameter Comparison

Engineering Selection Recommendations

All four part numbers—0326020.MXCCP, 0326020.VXP, BK/MDA-20-R, and MDA-20-R—are active products with full RoHS3 compliance and REACH unaffected status. Selection between Littelfuse and Eaton variants depends on supply chain availability and existing certification requirements within your application.

The Littelfuse 0326020.MXCCP and 0326020.VXP carry identical electrical and mechanical specifications with approval from CE, CSA, KC, PSE, and UL agencies. The Eaton MDA-20-R variants (both standard and black-coded versions) provide equivalent functionality with CE, CSA, and UL certifications. All parts are suitable for direct substitution in 20 A, 250 V AC / 125 V DC circuit protection applications requiring ceramic cartridge fuses with slow-blow response characteristics.

Frequently Asked Questions (FAQ)

Q: Can BK/MDA-20-R and MDA-20-R be used interchangeably?

A: Yes. Both Eaton parts share identical electrical ratings, mechanical dimensions, and response characteristics. The "BK/" designation indicates black color coding; both versions are functionally equivalent for circuit protection purposes.

Q: Are Littelfuse and Eaton fuses interchangeable in the same holder?

A: Yes. All four part numbers conform to the 3AB, 3AG, 1/4" x 1-1/4" package standard with identical physical dimensions (0.250" Dia x 1.250" L). They are mechanically compatible with the same holder assemblies.

Q: What is the difference between 0326020.MXCCP and 0326020.VXP?

A: Both are Littelfuse ceramic cartridge fuses with identical electrical specifications, voltage ratings, current ratings, and response times. They differ only in packaging designation and are direct parametric equivalents.

Q: Do all substitute parts meet the same approval standards?

A: Littelfuse parts (0326020.MXCCP and 0326020.VXP) carry CE, CSA, KC, PSE, and UL approvals. Eaton parts (BK/MDA-20-R and MDA-20-R) carry CE, CSA, and UL approvals. Verify that your application requirements align with the specific certification set needed.

Q: Can these fuses be used in both AC and DC circuits?

A: Yes. All parts are rated for 250 V AC and 125 V DC operation, making them suitable for dual-voltage applications within these specified limits.
