Substitute Part Grouping Explanation

Substitution of the MDQ-1-8/10 is determined by strict equivalence across the following critical parameters:

• Current Rating: 1.8 A (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Physical Dimensions: 0.250" Dia x 1.250" L (exact match required)
• Mounting Configuration: Requires Holder (exact match required)

The substitute part BK/MDL-1-8/10-R meets all electrical and mechanical equivalence criteria. Both parts are manufactured by Eaton - Electronics Division and share identical functional specifications for circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

Both the MDQ-1-8/10 and BK/MDL-1-8/10-R are Active products from Eaton - Electronics Division with identical electrical and mechanical specifications. Selection between these parts is based on availability and compliance requirements:

MDQ-1-8/10: Carries CSA and UL approval certifications. Current inventory: 704 units.

BK/MDL-1-8/10-R: RoHS3 Compliant and REACH Unaffected. Current inventory: 1765 units. Moisture Sensitivity Level (MSL): 1 (Unlimited).

Both parts are classified under ECCN EAR99 and HTSUS 8536.10.0020. The BK/MDL-1-8/10-R offers higher inventory availability and explicit RoHS3 compliance documentation. Selection should be based on specific application compliance requirements and supply chain constraints.

Frequently Asked Questions (FAQ)

Q: Can the BK/MDL-1-8/10-R be used as a direct replacement for the MDQ-1-8/10?

A: Yes. Both parts are electrically and mechanically equivalent with identical current ratings (1.8 A), voltage ratings (250 V AC), fuse type (Cartridge, Glass), response time (Slow Blow), and physical dimensions (0.250" Dia x 1.250" L). Both require the same 3AB and 3AG holder configurations.

Q: Are there any differences in approval certifications between these parts?

A: The MDQ-1-8/10 carries CSA and UL approvals. The BK/MDL-1-8/10-R includes RoHS3 Compliance and REACH Unaffected status. Application requirements should determine which certification profile is necessary.

Q: Do these fuses have different moisture sensitivity levels?

A: The MDQ-1-8/10 lists MSL as Not Applicable. The BK/MDL-1-8/10-R specifies MSL: 1 (Unlimited). This difference does not affect electrical or mechanical substitution compatibility.

Q: What holder types are compatible with both parts?

A: Both the MDQ-1-8/10 and BK/MDL-1-8/10-R are designed for 3AB and 3AG holder configurations with 1/4" x 1-1/4" package dimensions. Verify holder compatibility with your specific circuit protection assembly.

Q: Are both parts suitable for AC and DC applications?

A: Both parts are rated for 250 V AC/DC operation. The 1.8 A slow-blow characteristic applies to both AC and DC circuit protection applications.
