MDA-V-8-R Ceramic Fuse Equivalent & Substitute Parts

Part Overview

The MDA-V-8-R is an 8 A, 250 V AC/DC ceramic cartridge fuse manufactured by Eaton - Electronics Division. This through-hole mounted fuse features a slow-blow response characteristic and is housed in a 3AB, 3AG package format with dimensions of 1/4" x 1-1/4" (6.76mm x 32.82mm). The part maintains Active product status with 716 units currently in stock.

Substitute parts are identified when equivalent electrical ratings, mechanical dimensions, and approval certifications align with the original specification, enabling direct replacement in circuit protection applications without design modification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDA-V-8-R is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Current Rating: 8 A (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)
• Mounting Type: Through Hole (exact match required)

Secondary Compliance Criteria:

• Approval Agencies: Must include CE, CSA, and UL certifications
• RoHS Status: ROHS3 Compliant

Two substitute parts meet these criteria: BK/MDA-V-8-R (direct manufacturer variant from Eaton) and 0325008.HXP (cross-manufacturer equivalent from Littelfuse Inc.).

Parameter Comparison

Engineering Selection Recommendations

BK/MDA-V-8-R (Eaton - Electronics Division): This part is a direct manufacturer variant of the MDA-V-8-R, supplied by the same manufacturer. All electrical parameters, mechanical dimensions, and approval certifications are identical. This substitute is suitable for applications requiring continuity with the original Eaton product line. Current inventory is 680 units.

0325008.HXP (Littelfuse Inc.): This cross-manufacturer substitute from Littelfuse Inc. meets all primary electrical and mechanical substitution criteria. The part carries expanded approval certifications (K-MARK, PSE in addition to CE, CSA, UL) and maintains ROHS3 compliance. Physical dimensions are within tolerance of the original specification (0.275" Dia x 1.288" L versus 0.266" Dia x 1.292" L). This substitute is suitable for applications where cross-manufacturer sourcing is acceptable. Current inventory is 1244 units.

Both substitutes are Active products with full regulatory compliance and are suitable for direct replacement in circuit protection applications matching the MDA-V-8-R electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can BK/MDA-V-8-R be used as a direct replacement for MDA-V-8-R? A: Yes. BK/MDA-V-8-R is supplied by Eaton - Electronics Division and shares identical electrical ratings (8 A, 250 V AC), fuse type (Cartridge, Ceramic), response time (Slow Blow), package format (3AB, 3AG, 1/4" x 1-1/4"), and approval certifications (CE, CSA, UL). It is a direct substitute.

Q: What are the differences between MDA-V-8-R and 0325008.HXP? A: Both parts share identical electrical ratings and package designations. The 0325008.HXP is manufactured by Littelfuse Inc. rather than Eaton. Physical dimensions are within tolerance (diameter 0.275" vs. 0.266"; length 1.288" vs. 1.292"). The 0325008.HXP carries additional certifications (K-MARK, PSE). Both are ROHS3 compliant and Active products.

Q: Are there any mechanical compatibility concerns with 0325008.HXP? A: No. Both parts use the 3AB, 3AG package format with 1/4" x 1-1/4" (Axial) designation. Physical dimension variations (0.009" diameter difference, 0.004" length difference) are within standard mechanical tolerances for through-hole cartridge fuse mounting.

Q: Which substitute should be selected for new designs? A: Selection depends on sourcing strategy. BK/MDA-V-8-R maintains manufacturer continuity with Eaton. 0325008.HXP from Littelfuse provides higher inventory availability (1244 units) and expanded international certifications. Both are functionally equivalent for the specified electrical application.

Q: Do all three parts meet the same regulatory requirements? A: All three parts are ROHS3 compliant and carry CE, CSA, and UL certifications. The 0325008.HXP additionally carries K-MARK and PSE certifications, providing broader geographic compliance coverage.
