Equivalent & Substitute Parts for MDA-V-1/10-R

Part Overview

The MDA-V-1/10-R is a 100 mA, 250 V AC/DC ceramic cartridge fuse manufactured by Eaton - Electronics Division. This component is classified as obsolete, necessitating identification of active substitute parts that maintain electrical and mechanical compatibility. The MDA-V-1/10-R features a slow-blow response characteristic and 3AB, 3AG package format with through-hole mounting. Substitute parts must match the specified current rating, voltage rating, response time, and physical dimensions to ensure direct replacement capability in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MDA-V-1/10-R are qualified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution validity:

Electrical Parameters:

• Current Rating: 100 mA (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Response Time: Slow Blow (exact match required)

Mechanical Parameters:

• Fuse Type: Cartridge, Ceramic (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (maintained across all substitutes)

All three substitute parts from Littelfuse Inc. (0325.100HXP, 0325.100MXP, 0325.100VXP) satisfy these criteria and are classified as active products with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

All three Littelfuse substitute parts (0325.100HXP, 0325.100MXP, 0325.100VXP) are qualified replacements for the obsolete MDA-V-1/10-R. Selection among these three substitutes should be based on availability and procurement requirements:

0325.100VXP - 1088 units in stock (highest availability)

0325.100MXP - 984 units in stock (high availability)

0325.100HXP - 782 units in stock (available)

All substitute parts maintain active product status with current manufacturing support from Littelfuse Inc., ensuring long-term supply chain reliability. All substitutes carry CE approval certification and ROHS3 compliance, meeting regulatory requirements equivalent to or exceeding the original component specifications.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 0325.100HXP, 0325.100MXP, or 0325.100VXP be used as direct replacements for the MDA-V-1/10-R?

A: Yes. All three Littelfuse parts match the required electrical parameters (100 mA, 250 V AC, slow-blow response) and mechanical specifications (3AB, 3AG package, through-hole mounting, 1/4" x 1-1/4" dimensions). Direct substitution is supported without circuit modification.

Q: What is the difference between the three Littelfuse substitute parts?

A: The 0325.100HXP, 0325.100MXP, and 0325.100VXP are electrically and mechanically identical. They differ only in internal construction variants and inventory availability. All three are functionally equivalent for this application.

Q: Are the physical dimensions compatible with existing PCB footprints?

A: The substitute parts have dimensions of 0.275" Dia x 1.288" L (6.99mm x 32.72mm), compared to the original 0.266" Dia x 1.292" L (6.76mm x 32.82mm). These minor dimensional variations remain within the 3AB, 3AG package specification tolerance and are compatible with standard through-hole fuse holders designed for this package format.

Q: Do the substitute parts have additional technical specifications?

A: Yes. The Littelfuse substitutes provide additional documented parameters including breaking capacity (100 A), melting I²t (0.087), operating temperature range (-55°C ~ 125°C), and DC cold resistance (33.55 Ohms). These specifications exceed the documentation available for the original MDA-V-1/10-R.

Q: What compliance certifications apply to the substitute parts?

A: All three Littelfuse substitutes carry CE approval and ROHS3 compliance certification. The original MDA-V-1/10-R did not specify approval agency certification, making the Littelfuse parts compliant with current regulatory standards.

Q: Is there a preferred substitute part among the three options?

A: Selection should be based on procurement availability and lead time requirements. All three parts are electrically and mechanically identical. The 0325.100VXP offers the highest current inventory level (1088 units).
