Equivalent & Substitute Parts for MDA-8/10-R

Part Overview

The MDA-8/10-R is an 800 mA, 250 V AC ceramic cartridge fuse manufactured by Eaton - Electronics Division. This component is classified as obsolete, requiring identification of active substitute parts for continued system support and procurement. The fuse operates with slow-blow response characteristics and requires a 3AB or 3AG holder with 1/4" x 1-1/4" dimensions. Due to obsolete status, equivalent active alternatives must be evaluated based on electrical ratings, mechanical compatibility, and approval certifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Primary Matching Criteria:

• Current Rating: 800 mA (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (mechanical compatibility required)
• Response Time: Slow Blow (functional characteristic match)
• Mounting Type: Requires Holder (system integration requirement)

Secondary Compatibility Factors:

• Fuse Type: Ceramic or Glass construction (both acceptable for this application)
• Size / Dimension: 0.250" Dia x 1.250" L or equivalent metric (6.35mm x 31.75mm)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

Substitute Parts Identified:

1. 0326.800HXP (Littelfuse Inc.) - Ceramic cartridge fuse, active status
2. 0326.800MXP (Littelfuse Inc.) - Ceramic cartridge fuse, active status
3. 0326.800VXP (Littelfuse Inc.) - Ceramic cartridge fuse, active status
4. 0001.2523 (SCHURTER Inc.) - Glass cartridge fuse, active status

All substitute parts meet the primary matching criteria of 800 mA, 250 V AC, 3AB/3AG package, and slow-blow response. Substitutes provide enhanced DC voltage ratings and active product status compared to the obsolete MDA-8/10-R.

Parameter Comparison

Engineering Selection Recommendations

Littelfuse 326 Series (0326.800HXP, 0326.800MXP, 0326.800VXP):

These ceramic cartridge fuses are direct functional equivalents to the MDA-8/10-R. All three Littelfuse parts share identical electrical ratings (800 mA, 250 V AC, 125 V DC), mechanical dimensions, and package specifications. The Littelfuse 326 series holds CE, CSA, and UL certifications, providing broader approval coverage than the obsolete MDA-8/10-R. Operating temperature range extends to -55°C ~ 125°C, supporting extended environmental applications. Breaking capacity specifications (100A AC, 10kA DC) are documented for circuit protection coordination. ROHS3 compliance and unlimited moisture sensitivity level (MSL 1) ensure regulatory and storage compatibility.

SCHURTER 0001.2523:

This glass cartridge fuse alternative meets all primary electrical and mechanical requirements (800 mA, 250 V AC, 3AB/3AG package, slow-blow response). The SCHURTER part provides enhanced DC breaking capacity (20kA DC) compared to Littelfuse alternatives, with cURus certification. Operating temperature range (-40°C ~ 85°C) is narrower than Littelfuse options. Glass construction differs from the ceramic MDA-8/10-R but maintains functional equivalence for AC-dominant applications. DC voltage rating (63 V) is lower than Littelfuse alternatives, requiring evaluation against system DC requirements.

Selection Basis:

For direct ceramic-to-ceramic substitution with maximum environmental range and multi-agency certification, the Littelfuse 326 series (0326.800HXP, 0326.800MXP, or 0326.800VXP) is the primary recommendation. For applications requiring enhanced DC breaking capacity or glass construction preference, the SCHURTER 0001.2523 is a valid alternative. All substitute parts are active products with documented inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the MDA-8/10-R be directly replaced with any of the substitute parts?

A: Yes. All identified substitute parts (0326.800HXP, 0326.800MXP, 0326.800VXP, and 0001.2523) meet the critical electrical parameters (800 mA, 250 V AC) and mechanical specifications (3AB/3AG package, 1/4" x 1-1/4" dimensions) required for direct substitution in the same holder assembly.

Q: What is the difference between the three Littelfuse 326 series parts?

A: The 0326.800HXP, 0326.800MXP, and 0326.800VXP are functionally identical in electrical ratings, mechanical dimensions, and certifications. Differences exist only in manufacturing lot tracking and inventory source designation. All three are interchangeable for circuit protection applications.

Q: Why does the SCHURTER 0001.2523 use glass construction instead of ceramic?

A: Glass and ceramic are both acceptable cartridge fuse materials for this current and voltage rating. Glass construction in the SCHURTER part provides enhanced DC breaking capacity (20kA DC versus 10kA DC for Littelfuse ceramic). Material selection depends on application-specific requirements for DC circuit protection and thermal characteristics.

Q: Are there DC voltage rating differences between substitutes?

A: Yes. The Littelfuse 326 series (0326.800HXP, 0326.800MXP, 0326.800VXP) are rated 125 V DC, while the SCHURTER 0001.2523 is rated 63 V DC. The MDA-8/10-R does not specify a DC rating. For applications with DC voltage exposure exceeding 63 V, the Littelfuse alternatives are required.

Q: Do all substitute parts have the same approval certifications?

A: No. Littelfuse 326 series parts hold CE, CSA, and UL certifications. The SCHURTER 0001.2523 holds cURus certification. System requirements may mandate specific approval agencies; verify certification requirements before final selection.

Q: What is the operating temperature range difference?

A: Littelfuse 326 series parts operate from -55°C to 125°C. The SCHURTER 0001.2523 operates from -40°C to 85°C. For applications requiring extended low-temperature operation below -40°C or high-temperature operation above 85°C, the Littelfuse alternatives provide broader environmental coverage.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts (0326.800HXP, 0326.800MXP, 0326.800VXP, and 0001.2523) are ROHS3 compliant, matching the regulatory status of the obsolete MDA-8/10-R.

Q: What inventory quantities are available for each substitute?

A: Littelfuse 0326.800HXP: 963 pcs; Littelfuse 0326.800MXP: 2380 pcs; Littelfuse 0326.800VXP: 820 pcs; SCHURTER 0001.2523: 1134 pcs. All parts are in stock as new original components.
