Equivalent & Substitute Parts for BK/MDA-V-10

Part Overview

The BK/MDA-V-10 is a 10 A 250 V AC/DC ceramic cartridge fuse manufactured by Eaton - Electronics Division, designed for through-hole mounting in 3AB, 3AG package format with 1/4" x 1-1/4" (Axial) dimensions. This part is classified as obsolete, necessitating identification of active equivalent alternatives to maintain circuit protection functionality in legacy and ongoing applications. Substitute parts must maintain identical electrical ratings, mechanical compatibility, and approval certifications to ensure direct interchangeability without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/MDA-V-10 is determined by strict equivalence across the following parameters: current rating (10 A), voltage rating (250 V AC), fuse type (ceramic cartridge), response time (slow blow), and package format (3AB, 3AG, 1/4" x 1-1/4" axial). All substitute parts must maintain these core electrical and mechanical specifications to ensure direct circuit compatibility without modification.

The substitute parts are grouped into two categories:

Direct Manufacturer Equivalents (Eaton - Electronics Division): BK/MDA-V-10-R and MDA-V-10-R are active-status alternatives from the original manufacturer, differing only in packaging designation and product status. Both maintain identical electrical performance and approval certifications.

Cross-Manufacturer Equivalent (Littelfuse Inc.): The 0325010.HXP from Littelfuse Inc. meets all core electrical and mechanical parameters while offering enhanced breaking capacity (400 A vs. 200 A) and extended operating temperature range (-55°C ~ 125°C). This part is certified to equivalent approval standards (CE, CSA, UL) and maintains RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

For Direct Manufacturer Continuity: BK/MDA-V-10-R and MDA-V-10-R are preferred substitutes when maintaining the original manufacturer supply chain is required. Both parts are active-status products from Eaton - Electronics Division with identical electrical specifications to the obsolete BK/MDA-V-10. BK/MDA-V-10-R is available in bulk packaging with 901 pieces in stock, while MDA-V-10-R offers 820 pieces in stock. Both achieve CE, CSA, and UL certifications and comply with RoHS3 standards, addressing the non-compliance status of the original part.

For Enhanced Performance and Compliance: The 0325010.HXP from Littelfuse Inc. provides superior breaking capacity (400 A vs. 200 A) and extended operating temperature range (-55°C ~ 125°C), making it suitable for applications requiring enhanced fault tolerance or operation in temperature-extreme environments. This part maintains all core electrical and mechanical compatibility while offering broader approval certifications (CE, CSA, K-MARK, PSE, UL) and RoHS3 compliance. Inventory availability is 829 pieces.

All three substitute parts are mechanically and electrically compatible with the original BK/MDA-V-10 circuit application without modification to fuse holders or circuit design.

Frequently Asked Questions (FAQ)

Q: Can BK/MDA-V-10-R and MDA-V-10-R be used interchangeably with BK/MDA-V-10?

A: Yes. Both parts maintain identical current rating (10 A), voltage rating (250 V AC), fuse type (ceramic cartridge), response time (slow blow), and package format (3AB, 3AG, 1/4" x 1-1/4" axial). They are direct electrical and mechanical equivalents suitable for direct substitution in existing circuits.

Q: What is the difference between BK/MDA-V-10-R and MDA-V-10-R?

A: Both parts are manufactured by Eaton - Electronics Division with identical electrical specifications and certifications. The difference is in part number designation and packaging format. Both are active-status products with equivalent performance.

Q: Is the Littelfuse 0325010.HXP a direct substitute?

A: Yes, the 0325010.HXP meets all core electrical and mechanical requirements: 10 A current rating, 250 V AC voltage rating, ceramic cartridge fuse type, slow blow response, and 3AB, 3AG package format. It provides enhanced breaking capacity (400 A vs. 200 A) and extended operating temperature range (-55°C ~ 125°C), making it suitable for applications requiring higher fault tolerance or temperature extremes.

Q: Are there any compliance differences between the substitute parts?

A: The original BK/MDA-V-10 is RoHS non-compliant. All three substitute parts (BK/MDA-V-10-R, MDA-V-10-R, and 0325010.HXP) are RoHS3 compliant. The Littelfuse 0325010.HXP offers the broadest approval certifications (CE, CSA, K-MARK, PSE, UL) compared to the Eaton alternatives (CE, CSA, UL).

Q: Will the substitute parts fit existing fuse holders designed for BK/MDA-V-10?

A: Yes. All substitute parts maintain the 3AB, 3AG package format with 1/4" x 1-1/4" (Axial) dimensions, ensuring mechanical compatibility with existing through-hole fuse holders. Dimensional variations are negligible (0.266" to 0.275" diameter, 1.288" to 1.292" length) and fall within standard fuse holder tolerances.

Q: What is the significance of the Melting I²t difference?

A: Melting I²t indicates the thermal energy required to melt the fuse element. The original BK/MDA-V-10 has a Melting I²t of 1491.3, while BK/MDA-V-10-R and MDA-V-10-R have 332, and 0325010.HXP has 137. All parts maintain the same 10 A current rating and slow blow response time, ensuring equivalent circuit protection behavior at rated current. The I²t difference reflects manufacturing process variations between manufacturers and does not affect substitutability for the specified 10 A application.

Q: Which substitute part should be selected for new designs?

A: For new designs, either BK/MDA-V-10-R, MDA-V-10-R, or 0325010.HXP are acceptable. Selection should be based on supply chain preference (Eaton vs. Littelfuse), required certifications, and environmental operating conditions. The Littelfuse 0325010.HXP is recommended for applications requiring extended temperature range (-55°C ~ 125°C) or enhanced breaking capacity (400 A).
