Substitute Part Grouping Explanation

Substitute parts for the Eaton BK/AGW-2 are identified through strict parametric matching of the following critical characteristics:

Electrical Parameters:

• Current Rating: 2 A (exact match required)
• Voltage Rating (AC): 32 V (exact match required)
• Breaking Capacity: 1 kA (exact match required)
• DC Cold Resistance: 0.056 Ohms (exact match required)

Mechanical Parameters:

• Fuse Type: Cartridge, Glass (exact match required)
• Package / Case: 7AG, 1/4" x 7/8" (exact match required)
• Size / Dimension: 0.250" Dia x 0.875" L (exact match required)
• Mounting Type: Requires Holder (exact match required)

Functional Parameters:

• Response Time: Fast Blow (exact match required)

Only components matching all specified parameters are listed as substitutes. This ensures mechanical fit within existing fuse holders and electrical performance equivalence in circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

Both the main part BK/AGW-2 and the substitute AGW-2 maintain Active product status, indicating ongoing manufacturer support and availability. Both components are RoHS non-compliant and carry identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Selection between these parts should be based on inventory availability and supply chain considerations. The main part BK/AGW-2 currently has 1080 pieces in stock, while the substitute AGW-2 has 894 pieces available. Both parts are sourced from the same manufacturer (Eaton - Electronics Division) and belong to the same AGW series, ensuring consistent manufacturing standards and performance characteristics.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications, including current rating (2 A), voltage rating (32 V AC), fuse type (Cartridge, Glass), response time (Fast Blow), and package dimensions (7AG, 1/4" x 7/8"). Direct substitution is supported without circuit modification.

Q: What determines compatibility between these fuse cartridges?

A: Compatibility is determined by exact matching of current rating, voltage rating, fuse type, response time, and mechanical package dimensions. The 7AG form factor and 1/4" x 7/8" dimensions ensure physical fit within standard fuse holders designed for this specification.

Q: Are there any compliance differences between the main part and substitute?

A: No. Both parts carry identical RoHS non-compliant status and MSL ratings. Both maintain Active product status with ongoing manufacturer support.

Q: What is the significance of the 0.056 Ohms DC Cold Resistance specification?

A: DC Cold Resistance is a measured electrical characteristic of the fuse element at room temperature. Matching this value across substitute parts ensures equivalent electrical performance and response characteristics in circuit protection applications.

Q: Does the 1 kA breaking capacity apply to both AC and DC circuits?

A: The breaking capacity specification of 1 kA is provided at the rated voltage. Application context determines whether AC or DC operation is appropriate; the voltage rating of 32 V applies to both AC and DC conditions.
