Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MDA-10-R are qualified based on the following critical parameters:

Electrical Compatibility:

• Current Rating: 10 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Response Time: Slow Blow (exact match required)

Mechanical Compatibility:

• Fuse Type: Cartridge, Ceramic (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Mounting Type: Requires Holder (exact match required)
• Size / Dimension: 0.250" Dia x 1.250" L (exact match required)

Compliance & Certification:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• Approval Agencies: CE, CSA, UL (baseline certifications)

All substitute parts listed meet these criteria and are interchangeable within applications designed for the MDA-10-R specification.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and meet the core electrical and mechanical requirements for direct substitution with the MDA-10-R. Selection among these parts should be based on the following factors:

Manufacturer Preference: BK/MDA-10-R maintains identical Eaton - Electronics Division sourcing for organizations requiring single-manufacturer standardization.

Littelfuse Alternatives: The 0326010.HXP, 0326010.MXP, and 0326010.VXP parts provide Littelfuse sourcing options with extended approval certifications (K-MARK, PSE, KC) suitable for international applications. These parts feature higher breaking capacity (400 A versus 200 A) and specified operating temperature range (-55°C ~ 125°C).

Inventory Availability: 0326010.MXP offers the highest inventory level (16,029 pcs) among all substitute options, supporting rapid procurement requirements.

Compliance Scope: All parts maintain ROHS3 compliance and baseline CE, CSA, and UL certifications. Littelfuse variants include additional regional certifications for expanded market applicability.

Frequently Asked Questions (FAQ)

Q: Can 0326010.HXP, 0326010.MXP, and 0326010.VXP be used interchangeably with MDA-10-R?

A: Yes. All three Littelfuse parts are direct substitutes. They share identical electrical ratings (10 A, 250 V AC), fuse type (ceramic cartridge), response time (slow blow), and mechanical dimensions (3AB, 3AG, 1/4" x 1-1/4"). The parts differ in regional approval certifications and are functionally equivalent for applications designed for the MDA-10-R specification.

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

A: BK/MDA-10-R is an Eaton - Electronics Division variant of the MDA-10-R with identical electrical and mechanical specifications. Both parts are interchangeable. The primary difference is inventory availability (3,117 pcs for BK/MDA-10-R versus 880 pcs for MDA-10-R).

Q: Are there differences in breaking capacity between the Eaton and Littelfuse parts?

A: Yes. The MDA-10-R and BK/MDA-10-R have a breaking capacity of 200 A at rated voltage, while the Littelfuse parts (0326010.HXP, 0326010.MXP, 0326010.VXP) have a breaking capacity of 400 A. Both ratings are suitable for standard 10 A, 250 V AC applications. Applications requiring specific breaking capacity specifications should reference the circuit design requirements.

Q: Do the Littelfuse parts have operating temperature specifications?

A: Yes. The Littelfuse parts (0326010.HXP, 0326010.MXP, 0326010.VXP) are rated for -55°C ~ 125°C operating temperature. The Eaton parts (MDA-10-R and BK/MDA-10-R) do not specify an operating temperature range in the provided data.

Q: Which part should be selected for international applications?

A: The Littelfuse variants (0326010.HXP, 0326010.MXP, 0326010.VXP) include extended regional certifications (K-MARK, PSE, KC) in addition to CE, CSA, and UL approvals, making them suitable for broader international deployment. Selection should align with specific regional market requirements.

Q: Are all parts ROHS3 compliant?

A: Yes. All five parts (MDA-10-R, BK/MDA-10-R, 0326010.HXP, 0326010.MXP, and 0326010.VXP) are ROHS3 compliant.

Q: What holder types are compatible with these fuses?

A: All parts require a 3AB or 3AG holder. The fuses are cartridge-type and cannot be used without an appropriate holder assembly.
