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

Part Overview

The BK/MDA-V-10-R is a ceramic cartridge fuse manufactured by Eaton - Electronics Division, rated for 10 A at 250 V AC/DC with slow-blow response characteristics. This through-hole component is designed for circuit protection applications requiring a 3AB, 3AG form factor with 1/4" x 1-1/4" axial dimensions. The part maintains active product status with 901 units in current inventory. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when supply chain diversification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/MDA-V-10-R is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 10 A
• Voltage Rating (AC): 250 V
• Fuse Type: Cartridge, Ceramic
• Response Time: Slow Blow
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial)
• Mounting Type: Through Hole

Both identified substitute parts (0325010.HXP and 0325010.MXP, both manufactured by Littelfuse Inc.) satisfy all mandatory matching parameters. These parts are functionally equivalent for direct replacement in applications requiring the specified electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and comply with ROHS3 requirements. The BK/MDA-V-10-R (Eaton) and both Littelfuse substitutes (0325010.HXP and 0325010.MXP) carry CE, CSA, and UL certifications, meeting standard regulatory compliance for circuit protection applications.

The Littelfuse alternatives provide higher breaking capacity (400 A versus 200 A) and extended operating temperature range (-55°C ~ 125°C), which may offer enhanced performance margins in certain applications. However, these differences do not affect functional equivalence for standard 10 A, 250 V AC/DC circuit protection duty.

Selection between the three parts should be based on availability, lead time, and supply chain requirements. The 0325010.MXP variant currently maintains the highest inventory level (1580 units), followed by the BK/MDA-V-10-R (901 units) and 0325010.HXP (829 units).

Frequently Asked Questions (FAQ)

Q: Can 0325010.HXP and 0325010.MXP be used interchangeably with BK/MDA-V-10-R?

A: Yes. All three parts share identical electrical ratings (10 A, 250 V AC/DC), fuse type (ceramic cartridge), response characteristic (slow blow), and mechanical package (3AB, 3AG, 1/4" x 1-1/4" axial). They are functionally equivalent for direct replacement in through-hole circuit protection applications.

Q: What is the difference between 0325010.HXP and 0325010.MXP?

A: Both Littelfuse parts are electrically and mechanically identical. They carry the same current rating, voltage rating, breaking capacity, and operating temperature range. Selection between them should be based on availability and procurement lead time.

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

A: The BK/MDA-V-10-R has a diameter of 0.266" (6.76 mm) and length of 1.292" (32.82 mm). The Littelfuse substitutes have a diameter of 0.275" (6.99 mm) and length of 1.288" (32.72 mm). These minor variations remain within the 3AB, 3AG form factor specification and do not affect mechanical fit in standard through-hole applications.

Q: Do all parts carry the same regulatory certifications?

A: The BK/MDA-V-10-R carries CE, CSA, and UL certifications. The Littelfuse substitutes carry CE, CSA, K-MARK, PSE, and UL certifications, providing broader international compliance coverage.

Q: What is the significance of the different melting I²t values?

A: The BK/MDA-V-10-R has a melting I²t of 332, while both Littelfuse substitutes have a melting I²t of 137. Both values are provided for reference in thermal analysis. The lower I²t of the Littelfuse parts indicates faster thermal response, which may be relevant in applications with specific thermal protection requirements.
