Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AGX-7 are identified based on strict parametric equivalence. The following electrical and mechanical parameters must match identically for a part to qualify as a direct substitute:

• Current Rating: 7 A
• Voltage Rating (AC): 250 V
• Fuse Type: Cartridge, Glass
• Response Time: Fast Blow
• Package / Case: 8AG, 1/4" x 1"
• Size / Dimension: 0.250" Dia x 1.000" L (6.35mm x 25.40mm)
• Breaking Capacity @ Rated Voltage: 200 A
• DC Cold Resistance: 0.015 Ohms
• Approval Agency: cULus

Parts meeting all these criteria are classified as parametric equivalents and may be used interchangeably in applications designed for the AGX-7.

Parameter Comparison

Engineering Selection Recommendations

Both AGX-7 and BK/AGX-7 are Active products manufactured by Eaton - Electronics Division and carry cULus approval certification. All critical electrical parameters—current rating, voltage rating, breaking capacity, and DC cold resistance—are identical. Physical dimensions and package specifications match exactly. Both parts are classified as fast-blow glass cartridge fuses in the 8AG form factor.

Selection between AGX-7 and BK/AGX-7 may be based on inventory availability, procurement lead time, or supply chain requirements. Both parts are suitable for direct substitution in applications requiring a 7 A 250 V AC/DC fast-blow fuse cartridge with 8AG holder compatibility.

Frequently Asked Questions (FAQ)

Q: Can BK/AGX-7 be used as a direct replacement for AGX-7?

A: Yes. BK/AGX-7 is a parametric equivalent to AGX-7. All electrical specifications (7 A current rating, 250 V AC voltage rating, 200 A breaking capacity, 0.015 Ohms DC cold resistance), mechanical dimensions (0.250" Dia x 1.000" L), fuse type (cartridge, glass), response time (fast blow), and approval certifications (cULus) are identical. Both parts require an 8AG fuse holder for installation.

Q: What are the key parameters that determine substitutability for the AGX-7?

A: Substitutability is determined by matching the following parameters: current rating (7 A), voltage rating (250 V AC), fuse type (cartridge, glass), response time (fast blow), package designation (8AG), physical dimensions (0.250" Dia x 1.000" L), breaking capacity (200 A), and DC cold resistance (0.015 Ohms). All substitute parts must also carry cULus approval and require holder mounting.

Q: Are there any differences in RoHS compliance between AGX-7 and BK/AGX-7?

A: Both AGX-7 and BK/AGX-7 are classified as RoHS non-compliant. This status is consistent across both parts.

Q: What holder is required for the AGX-7 and BK/AGX-7?

A: Both parts require an 8AG fuse holder. The 8AG designation specifies the holder type compatible with these 1/4" x 1" cartridge fuses.

Q: Can these fuses be used in DC applications?

A: Yes. Both AGX-7 and BK/AGX-7 are rated for 250 V AC/DC operation. The DC cold resistance specification (0.015 Ohms) is provided for DC circuit applications.
