Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/MDA-1-6/10-R is determined by the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 1.6 A
• Voltage Rating - AC: 250 V
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4"
• Response Time: Slow Blow
• Mounting Type: Requires Holder
• Physical Dimensions: 0.250" Dia x 1.250" L

Acceptable Variation Parameters:

• Fuse Type: Ceramic or Glass construction both acceptable for AC applications
• Voltage Rating - DC: Additional DC rating capability does not restrict substitution
• Melting I²t: Variation within acceptable thermal response range
• DC Cold Resistance: Minor variations acceptable within operational tolerance

The identified substitute parts meet all mandatory matching parameters and maintain compatibility with existing holder assemblies and circuit protection requirements.

Engineering Selection Recommendations

032601.6HXP (Littelfuse Inc.) - Direct Ceramic Substitute

The 032601.6HXP is a direct functional equivalent to the BK/MDA-1-6/10-R. Both parts are ceramic cartridge fuses with identical current and AC voltage ratings, response characteristics, and physical form factor. The Littelfuse part provides additional DC voltage capability (125 V DC) and extended operating temperature range (-55°C ~ 125°C). Approval certifications include CE, CSA, PSE, and UL, providing comprehensive regulatory coverage. This part is suitable for direct replacement in applications where the primary part is unavailable.

0001.2526 (SCHURTER Inc.) - Glass Cartridge Alternative

The 0001.2526 is a glass cartridge fuse that matches the BK/MDA-1-6/10-R in current rating, AC voltage rating, response time, and physical dimensions. The primary distinction is the fuse element material (glass versus ceramic). This part carries cURus certification and maintains ROHS3 compliance. The glass construction provides different thermal and breaking capacity characteristics (1.5 kA AC, 20 kA DC) compared to the ceramic alternatives. Selection of this part is appropriate for applications where glass fuse construction is acceptable and where the specified breaking capacity meets circuit requirements.

All three parts maintain active product status and ROHS3 compliance, ensuring continued availability and environmental regulatory adherence.

Frequently Asked Questions (FAQ)

Q: Can the 032601.6HXP replace the BK/MDA-1-6/10-R in all applications?

A: The 032601.6HXP is electrically and mechanically compatible with the BK/MDA-1-6/10-R for AC circuit protection applications. Both parts share identical current ratings (1.6 A), AC voltage ratings (250 V), response characteristics (slow blow), and physical form factors (3AB, 3AG, 1/4" x 1-1/4"). The Littelfuse part includes additional DC voltage capability and extended temperature range, which do not restrict substitution.

Q: What is the difference between the ceramic and glass fuse options?

A: The BK/MDA-1-6/10-R and 032601.6HXP are ceramic cartridge fuses, while the 0001.2526 is a glass cartridge fuse. All three parts meet the same current and AC voltage specifications and fit the same holder assemblies. The material difference affects thermal response characteristics and breaking capacity ratings. Ceramic and glass fuses are both acceptable for AC applications when electrical specifications match.

Q: Are all three parts compatible with existing 3AB, 3AG fuse holders?

A: Yes. All three parts are designed for 3AB, 3AG form factor holders and share the same physical dimensions (0.250" Dia x 1.250" L). The 0001.2526 has a dimension of 0.250" Dia x 1.252" L, which represents a negligible variation and maintains compatibility with standard 3AB, 3AG holder assemblies.

Q: Do all substitute parts carry the same regulatory certifications?

A: The BK/MDA-1-6/10-R carries CE, CSA, and UL certifications. The 032601.6HXP carries CE, CSA, PSE, and UL certifications, providing additional regulatory coverage. The 0001.2526 carries cURus certification. All parts are ROHS3 compliant. Selection should be based on the specific regulatory requirements of the target application.

Q: What is the significance of the melting I²t values?

A: The melting I²t value indicates the thermal energy required to melt the fuse element. The BK/MDA-1-6/10-R has a melting I²t of 4.6, the 032601.6HXP has 45, and the 0001.2526 has 4.2. These values reflect the thermal response characteristics of each fuse. The 032601.6HXP exhibits a higher melting I²t, indicating different thermal behavior. Selection should be based on circuit protection requirements and thermal response specifications.

Q: Can these fuses be used in DC applications?

A: The BK/MDA-1-6/10-R is rated for 250 V AC with no specified DC rating. The 032601.6HXP is rated for 250 V AC and 125 V DC. The 0001.2526 is rated for 250 V AC and 63 V DC. Use in DC applications requires verification that the selected part's DC voltage rating meets or exceeds the circuit voltage. The BK/MDA-1-6/10-R should not be used in DC circuits without confirmation of suitability.
