Substitute Part Grouping Explanation

Substitution eligibility for the MDL-2/10-R is determined by strict equivalence across the following critical parameters:

Current Rating: All substitute parts must be rated at 200 mA.

Voltage Rating (AC): All substitute parts must be rated at 250 V AC.

Fuse Type: All substitute parts must be glass cartridge fuses with slow-blow response characteristics.

Package / Case: All substitute parts must fit 3AB and 3AG holders with dimensions of 1/4" x 1-1/4" (6.35mm x 31.75mm).

Breaking Capacity: All substitute parts must maintain 35A breaking capacity at rated voltage.

Approval Agencies: All substitute parts must hold CE, CSA, and UL certifications.

The identified substitute parts meet these criteria and are classified as follows:

Direct Manufacturer Equivalent: BK/MDL-2/10-R (Eaton - Electronics Division, bulk packaging variant)

Parametric Equivalents: 0313.200MXP and 0313.200VXP (Littelfuse Inc., Series 313)

Frequently Asked Questions (FAQ)

Q: Can BK/MDL-2/10-R be used as a direct replacement for MDL-2/10-R?

A: Yes. BK/MDL-2/10-R is a direct manufacturer equivalent from Eaton - Electronics Division. Both parts share identical electrical ratings (200 mA, 250 V AC), fuse type (cartridge, glass), response time (slow blow), package configuration (3AB, 3AG, 1/4" x 1-1/4"), and approval certifications (CE, CSA, UL). The primary difference is packaging format (bulk versus standard).

Q: Are Littelfuse 0313.200MXP and 0313.200VXP interchangeable with MDL-2/10-R?

A: Yes. Both Littelfuse parts are parametric equivalents that meet all critical specifications: 200 mA current rating, 250 V AC voltage rating, slow-blow response, glass cartridge type, 3AB/3AG holder compatibility, and 35A breaking capacity. All three manufacturers' parts hold CE, CSA, and UL certifications. The Littelfuse parts specify operating temperature range (-55°C to 125°C) and REACH Unaffected status.

Q: What are the key compatibility criteria for substitution?

A: Substitution requires equivalence across: current rating (200 mA), voltage rating (250 V AC), fuse type (cartridge, glass), response time (slow blow), package dimensions (0.250" Dia x 1.250" L), holder compatibility (3AB, 3AG), breaking capacity (35A), and regulatory approvals (CE, CSA, UL).

Q: Do all substitute parts fit existing 3AB and 3AG holders?

A: Yes. All substitute parts maintain identical physical dimensions of 0.250" Dia x 1.250" L (6.35mm x 31.75mm) and are specified for 3AB and 3AG holder applications.

Q: What is the difference between MDL-2/10-R and BK/MDL-2/10-R?

A: Both parts are manufactured by Eaton - Electronics Division and are electrically and mechanically identical. The designation "BK" indicates bulk packaging. BK/MDL-2/10-R specifies ROHS3 compliance and MSL 1 (Unlimited) rating, while MDL-2/10-R lists RoHS Compliant status without MSL specification.

Q: Are there operating temperature differences between substitute parts?

A: MDL-2/10-R and BK/MDL-2/10-R do not specify operating temperature ranges. Littelfuse parts 0313.200MXP and 0313.200VXP specify -55°C to 125°C operating temperature range. For applications requiring defined temperature specifications, Littelfuse parts provide explicit operating limits.

Q: Do all parts hold the same regulatory certifications?

A: Yes. All four part numbers (MDL-2/10-R, BK/MDL-2/10-R, 0313.200MXP, 0313.200VXP) hold CE, CSA, and UL approvals. Littelfuse parts additionally specify REACH Unaffected status.
