AGA-6 Glass Cartridge Fuse Equivalent & Substitute Parts

Part Overview

The AGA-6 is a fast-blow glass cartridge fuse manufactured by Eaton - Electronics Division, rated for 6 A at 125 V AC/DC. This component is designed for use in 1AG holder assemblies and provides circuit protection in applications requiring rapid response to overcurrent conditions. The part maintains active product status with 1071 units currently in stock. Substitute parts are identified based on identical electrical ratings, mechanical dimensions, and functional characteristics to ensure direct interchangeability in existing circuit protection designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AGA-6 fuse is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Current Rating: 6 A (exact match required)
• Voltage Rating: 125 V AC (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity: 1 kA (exact match required)
• DC Cold Resistance: 0.015 Ohms (exact match required)

Mechanical Equivalence Criteria:

• Fuse Type: Cartridge, Glass (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)
• Mounting Type: Requires Holder (exact match required)

Functional Equivalence Criteria:

• Series: AGA (same product family)
• Product Status: Active (current manufacturing status)

The substitute part BK/AGA-6 meets all electrical, mechanical, and functional equivalence criteria and is therefore a direct parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both AGA-6 and BK/AGA-6 are active products manufactured by Eaton - Electronics Division with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability: AGA-6 has 1071 units in stock, while BK/AGA-6 has 1095 units in stock. Both parts carry RoHS non-compliant status and MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. No compliance or certification differences exist between the two part numbers. Direct substitution is supported for all circuit protection applications requiring 6 A, 125 V AC/DC fast-blow fuse protection in 1AG holder assemblies.

Frequently Asked Questions (FAQ)

Q: Can BK/AGA-6 be used as a direct replacement for AGA-6?

A: Yes. BK/AGA-6 is a parametric equivalent with identical current rating (6 A), voltage rating (125 V AC), response time (Fast Blow), package dimensions (1AG, 1/4" x 5/8"), breaking capacity (1 kA), and DC cold resistance (0.015 Ohms). Both parts are manufactured by Eaton - Electronics Division and maintain active product status.

Q: What holder assembly is required for the AGA-6 fuse?

A: The AGA-6 requires a 1AG holder assembly. The fuse dimensions are 0.250" diameter by 0.625" length (6.35mm x 15.88mm), which conform to the 1AG standard cartridge fuse specification.

Q: Are there any compliance or regulatory differences between AGA-6 and BK/AGA-6?

A: No. Both parts share identical RoHS status (non-compliant), MSL rating (1 - Unlimited), ECCN classification (EAR99), and HTSUS code (8536.10.0020).

Q: What is the breaking capacity of the AGA-6 fuse?

A: The breaking capacity is 1 kA at the rated voltage of 125 V AC.

Q: What is the DC cold resistance specification?

A: The DC cold resistance for both AGA-6 and BK/AGA-6 is 0.015 Ohms.

Q: Can these fuses be used in DC applications?

A: The AGA-6 is rated for 125 V AC/DC operation. The 125 V rating applies to both AC and DC voltage conditions.

Q: What is the response time classification of this fuse?

A: Both AGA-6 and BK/AGA-6 are classified as Fast Blow fuses, providing rapid response to overcurrent conditions.
