MDA-V-15/100-R Equivalent & Substitute Parts Reference

Part Overview

The MDA-V-15/100-R is a 150 mA ceramic cartridge fuse rated for 250 V AC/DC operation, manufactured by Eaton - Electronics Division. This component is classified as obsolete, necessitating identification of active equivalent alternatives for ongoing circuit protection applications. The fuse features slow-blow response characteristics and is housed in a 3AB, 3AG form factor with axial through-hole mounting. Locating functionally equivalent substitutes is essential for system maintenance, repair, and new design implementations where this fuse type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MDA-V-15/100-R are determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Current Rating: 150 mA (exact match required)
• Voltage Rating: 250 V AC (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:

• RoHS3 Compliant (maintained across all substitutes)

All three Littelfuse 325 series fuses listed below satisfy these criteria without deviation. Substitution is based solely on matching these defined parameters; no additional performance assumptions are applied.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes:

The Littelfuse 325 series fuses (0325.150HXP, 0325.150MXP, 0325.150VXP) are direct functional equivalents to the obsolete MDA-V-15/100-R. All three parts maintain active product status, ensuring long-term availability and supply chain continuity. Each substitute carries CE approval certification and ROHS3 compliance, meeting current regulatory requirements.

Compliance Considerations:

The MDA-V-15/100-R does not specify approval agency or operating temperature range in the provided data. The Littelfuse substitutes provide CE certification and defined operating temperature range (-55°C ~ 125°C), offering enhanced documentation for compliance-critical applications.

Dimensional Compatibility:

Substitute parts exhibit minor dimensional variation (0.275" Dia x 1.288" L versus 0.266" Dia x 1.292" L). Both dimensions remain within the 3AB, 3AG form factor specification and are compatible with standard through-hole fuse holders designed for this package type.

Selection Basis:

Choice among the three Littelfuse substitutes is not differentiated by the electrical or mechanical parameters provided. All three parts are electrically and mechanically equivalent. Selection may be based on packaging preference (all listed as Bulk) or inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 0325.150HXP, 0325.150MXP, or 0325.150VXP be used as direct replacements for the MDA-V-15/100-R?

A: Yes. All three Littelfuse parts match the critical substitution parameters: 150 mA current rating, 250 V AC voltage rating, slow-blow response, ceramic cartridge type, 3AB/3AG package, and through-hole mounting. Dimensional variation is within acceptable tolerance for standard fuse holder compatibility.

Q: What is the difference between the three Littelfuse substitute part numbers?

A: The provided data indicates no electrical or mechanical differences between 0325.150HXP, 0325.150MXP, and 0325.150VXP. All three parts share identical specifications for current, voltage, response time, package, and operating characteristics. Differences, if any, are not documented in the provided parameters.

Q: Why is the MDA-V-15/100-R classified as obsolete?

A: Product status is determined by manufacturer designation. The Eaton MDA-V-15/100-R is listed as obsolete, indicating discontinued production. Active Littelfuse equivalents ensure continued availability for replacement and maintenance applications.

Q: Are there any compliance or certification differences between the main part and substitutes?

A: The MDA-V-15/100-R does not specify approval agency or operating temperature in the provided data. The Littelfuse substitutes carry CE certification and specify operating temperature range (-55°C ~ 125°C). Both the main part and substitutes are ROHS3 compliant.

Q: Will the Littelfuse substitutes fit existing fuse holders designed for the MDA-V-15/100-R?

A: The 3AB, 3AG form factor and through-hole mounting type are identical across all parts. Minor dimensional differences (0.009" diameter and 0.004" length variation) fall within standard fuse holder tolerance and do not prevent physical installation.

Q: What is the breaking capacity of the substitute fuses?

A: The Littelfuse substitutes specify 100A breaking capacity at rated voltage. The MDA-V-15/100-R does not provide breaking capacity data in the available parameters.
