Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BK/MDL-2/10 are classified based on strict electrical and mechanical parameter alignment. All identified substitutes maintain identical specifications across the following critical parameters:

• Current Rating: 200 mA
• Voltage Rating (AC): 250 V
• Fuse Type: Cartridge, Glass
• Response Time: Slow Blow
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4"
• Size / Dimension: 0.250" Dia x 1.250" L (6.35mm x 31.75mm)
• Breaking Capacity @ Rated Voltage: 35A

Substitutes are grouped into two categories:

Direct Manufacturer Equivalent: BK/MDL-2/10-R (Eaton - Electronics Division) represents the same fuse with alternative packaging configuration (Bulk vs. standard packaging).

Parametric Equivalents: 0313.200MXP and 0313.200VXP (Littelfuse Inc., Series 313) provide functional equivalence with identical electrical and mechanical characteristics, enabling cross-manufacturer substitution within the same application requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection - BK/MDL-2/10: Use the original part number for applications where RoHS compliance is not required and CSA/UL certification alone is sufficient. Current inventory of 1032 pieces supports immediate availability.

Direct Equivalent - BK/MDL-2/10-R: Select this Eaton equivalent when bulk packaging is preferred and RoHS3 compliance is required. This part maintains identical electrical and mechanical specifications while adding CE certification and improved environmental compliance. Inventory of 980 pieces ensures supply continuity.

Cross-Manufacturer Alternatives - 0313.200MXP and 0313.200VXP: These Littelfuse Series 313 fuses provide parametric equivalence with enhanced compliance certifications (CE, CSA, UL) and RoHS3 compliance. The 0313.200MXP offers the highest inventory availability (1396 pieces), while 0313.200VXP provides an alternative with 771 pieces in stock. Both parts include specified operating temperature ranges (-55°C ~ 125°C), supporting applications across extended environmental conditions.

Selection between 0313.200MXP and 0313.200VXP is based on procurement requirements and inventory allocation, as both parts maintain identical electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

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

A: Yes. BK/MDL-2/10-R is a direct manufacturer equivalent with identical current rating (200 mA), voltage rating (250 V), fuse type (Cartridge, Glass), response time (Slow Blow), package configuration (3AB, 3AG, 1/4" x 1-1/4"), and breaking capacity (35A). The primary difference is packaging format (Bulk) and enhanced RoHS3 compliance.

Q: Are Littelfuse 0313.200MXP and 0313.200VXP compatible with 3AB and 3AG holders?

A: Yes. Both Littelfuse parts maintain the identical package specification (3AB, 3AG, 1/4" x 1-1/4") and physical dimensions (0.250" Dia x 1.250" L), ensuring mechanical compatibility with existing holder applications.

Q: What is the difference between 0313.200MXP and 0313.200VXP?

A: Both parts are parametrically equivalent with identical electrical specifications (200 mA, 250 V AC, Slow Blow response, 35A breaking capacity) and mechanical dimensions. Selection between these two Littelfuse alternatives is based on inventory availability and procurement requirements, as no functional differences exist.

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

A: BK/MDL-2/10 carries CSA and UL certifications. BK/MDL-2/10-R, 0313.200MXP, and 0313.200VXP all carry CE, CSA, and UL certifications, providing broader regulatory coverage.

Q: What is the significance of the DC Cold Resistance variation among these parts?

A: DC Cold Resistance values (BK/MDL-2/10: 4.115 Ohms; BK/MDL-2/10-R: 5.234 Ohms; 0313.200MXP and 0313.200VXP: 6.59 Ohms) reflect manufacturing variations within acceptable tolerances. These variations do not affect functional performance in standard circuit protection applications where the fuse operates at rated current and voltage specifications.

Q: Are the Littelfuse parts RoHS compliant?

A: Yes. Both 0313.200MXP and 0313.200VXP are ROHS3 Compliant with REACH Unaffected status, supporting applications requiring environmental compliance standards.
