Equivalent & Substitute Parts for MDA-V-1/100-R

Part Overview

The MDA-V-1/100-R is a 10 mA ceramic cartridge fuse rated for 250 V AC/DC operation, manufactured by Eaton - Electronics Division. This component features a slow-blow response characteristic and is housed in a 3AB, 3AG form factor with axial through-hole mounting. The product is currently classified as obsolete, necessitating identification of active equivalent alternatives to maintain circuit protection functionality in applications requiring this specific electrical and mechanical configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDA-V-1/100-R is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Current Rating: 10 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" (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)
• RoHS Compliance: ROHS3 Compliant (minimum requirement)

All identified substitute parts meet these criteria. The primary distinction between the main part and substitutes is product status: the original MDA-V-1/100-R is obsolete, while all substitute options are active products. Packaging format differences (tape/reel versus bulk) do not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

Primary Recommendation: BK/MDA-V-1/100R

The BK/MDA-V-1/100R represents the direct equivalent substitute for the obsolete MDA-V-1/100-R. Both components are manufactured by Eaton - Electronics Division and share identical electrical specifications and mechanical dimensions. The BK/MDA-V-1/100R maintains active product status with 758 units in stock, ensuring supply continuity. This option eliminates cross-manufacturer compatibility considerations and preserves design consistency within Eaton component families.

Secondary Recommendations: Littelfuse 325 Series (0325.010HXP, 0325.010MXP, 0325.010VXP)

The three Littelfuse alternatives from the 325 series provide functionally equivalent substitution with additional documented specifications. All three variants meet the critical electrical and mechanical parameters required for direct replacement. These components carry CE approval certification and specify operating temperature range (-55°C ~ 125°C) and breaking capacity (100A), providing enhanced technical documentation compared to the original part. Littelfuse components demonstrate higher inventory availability (773–1023 units per variant).

Dimensional Consideration:

Littelfuse substitutes exhibit minor dimensional variation: 0.275" diameter versus 0.266" for the original specification. This 0.009" difference remains within typical through-hole PCB tolerance specifications and does not preclude mechanical compatibility in standard axial component mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the BK/MDA-V-1/100R be used as a direct replacement for MDA-V-1/100-R?

A: Yes. Both components are manufactured by Eaton - Electronics Division and share identical current rating (10 mA), voltage rating (250 V AC), fuse type (ceramic cartridge), response time (slow blow), package designation (3AB, 3AG), and mounting configuration (through-hole axial). The BK/MDA-V-1/100R is the active product variant of the obsolete MDA-V-1/100-R.

Q: Are Littelfuse 325 series fuses compatible with the original MDA-V-1/100-R application?

A: Yes. The Littelfuse 0325.010HXP, 0325.010MXP, and 0325.010VXP all match the critical electrical parameters (10 mA current rating, 250 V AC voltage rating, ceramic cartridge type, slow-blow response) and mechanical form factor (3AB, 3AG, 1/4" x 1-1/4" axial). These components are functionally equivalent substitutes.

Q: What is the significance of the dimensional difference between Eaton and Littelfuse variants?

A: Littelfuse components measure 0.275" diameter compared to 0.266" for Eaton parts, a difference of 0.009". This variation falls within standard through-hole PCB tolerance specifications and does not affect mechanical fit in typical axial component mounting applications. Both form factors conform to the 3AB, 3AG standard designation.

Q: Do all substitute parts carry the same certifications as the original MDA-V-1/100-R?

A: The original MDA-V-1/100-R does not specify approval agency certification. The Littelfuse substitutes (0325.010HXP, 0325.010MXP, 0325.010VXP) carry CE approval and specify operating temperature range (-55°C ~ 125°C) and breaking capacity (100A). The Eaton BK/MDA-V-1/100R does not specify these additional certifications. Component selection should align with application-specific certification requirements.

Q: What is the difference between the three Littelfuse part numbers (0325.010HXP, 0325.010MXP, 0325.010VXP)?

A: All three Littelfuse variants share identical electrical specifications, mechanical dimensions, and performance characteristics. The part number suffix variation reflects internal Littelfuse product line differentiation. From an engineering substitution perspective, all three are equivalent alternatives. Selection may be based on inventory availability or supply chain preference.

Q: Is RoHS compliance maintained across all substitute options?

A: Yes. The original MDA-V-1/100-R and all identified substitutes (BK/MDA-V-1/100R, 0325.010HXP, 0325.010MXP, 0325.010VXP) are ROHS3 compliant, meeting environmental regulatory requirements for lead-free and restricted substance compliance.
