Substitute Part Grouping Explanation

Substitute parts for the AGA-1-1/2 are identified based on strict equivalence of the following critical parameters:

• Current Rating: 1.5 A (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 1AG, 1/4" x 5/8" (exact match required)
• Size / Dimension: 0.250" Dia x 0.625" L (exact match required)
• DC Cold Resistance: 0.076 Ohms (exact match required)
• Mounting Type: Requires Holder (exact match required)
• Approval Agency: UL (exact match required)

The substitute part BK/AGA-1-1/2 meets all electrical and mechanical equivalence criteria. Both parts are manufactured by Eaton - Electronics Division and carry active product status with UL approval.

Parameter Comparison

Engineering Selection Recommendations

Both the AGA-1-1/2 and BK/AGA-1-1/2 are suitable for direct substitution in applications requiring a 1.5 A, 250 V AC/DC fast-blow glass cartridge fuse in 1AG form factor. Both parts carry active product status and UL approval certification, confirming compliance with applicable electrical safety standards.

The primary distinction between these parts is the breaking capacity rating: the AGA-1-1/2 is rated at 100 A breaking capacity, while the BK/AGA-1-1/2 is rated at 35 A breaking capacity. Selection between these parts should be based on the specific breaking capacity requirement of the application circuit. All other electrical and mechanical parameters are identical.

Both parts are RoHS non-compliant and carry Moisture Sensitivity Level 1 (Unlimited). Both are classified under ECCN EAR99 and HTSUS 8536.10.0020.

Frequently Asked Questions (FAQ)

Q: Can BK/AGA-1-1/2 be used as a direct replacement for AGA-1-1/2?

A: Yes, BK/AGA-1-1/2 is electrically and mechanically equivalent to AGA-1-1/2 for all critical parameters including current rating, voltage rating, fuse type, response time, package form factor, and physical dimensions. Both parts fit 1AG fuse holders and carry identical UL approval.

Q: What is the difference between AGA-1-1/2 and BK/AGA-1-1/2?

A: The primary difference is the breaking capacity rating. AGA-1-1/2 has a breaking capacity of 100 A at rated voltage, while BK/AGA-1-1/2 has a breaking capacity of 35 A at rated voltage. All other specifications are identical.

Q: Which part should I select based on breaking capacity?

A: Breaking capacity selection depends on the maximum fault current expected in your application circuit. Select the part whose breaking capacity rating meets or exceeds your circuit's maximum fault current requirement.

Q: Are both parts currently available?

A: Yes. AGA-1-1/2 has 825 pieces in new original stock, and BK/AGA-1-1/2 has 1038 pieces in new original stock.

Q: Do these fuses require a specific holder?

A: Yes. Both AGA-1-1/2 and BK/AGA-1-1/2 require a 1AG fuse holder. They are not designed for direct installation without a compatible holder.

Q: Are these parts RoHS compliant?

A: No. Both AGA-1-1/2 and BK/AGA-1-1/2 are RoHS non-compliant.

Q: What is the physical size of these fuses?

A: Both parts measure 0.250" diameter by 0.625" length (6.35mm x 15.88mm).
