AGA-5 Equivalent & Substitute Parts Reference

Part Overview

The AGA-5 is a fast-blow glass cartridge fuse rated at 5 A, 125 V AC/DC, manufactured by Eaton - Electronics Division. This component is designed for circuit protection in applications requiring cartridge-style fuses with 1AG form factor (1/4" x 5/8"). The part maintains active product status and is stocked in original condition. Substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part number is unavailable.

Substitute Part Grouping Explanation

Substitute parts for the AGA-5 are identified based on strict parametric equivalence across the following critical specifications:

Substitution Criteria:

• Current Rating: 5 A (exact match required)
• Voltage Rating (AC): 125 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)
• Breaking Capacity @ Rated Voltage: 1 kA (exact match required)
• DC Cold Resistance: 0.017 Ohms (exact match required)
• Mounting Type: Requires Holder (exact match required)

The substitute part BK/AGA-5 meets all parametric requirements for direct substitution in applications currently specified for AGA-5.

Parameter Comparison

Engineering Selection Recommendations

Both AGA-5 and BK/AGA-5 are active products manufactured by Eaton - Electronics Division with identical electrical and mechanical specifications. Selection between these part numbers is based on availability and inventory status:

AGA-5: 870 pieces in stock. Primary part number for new designs and standard procurement.

BK/AGA-5: 1,889 pieces in stock. Substitute part number with higher inventory availability. Suitable for immediate fulfillment when primary part number stock is depleted.

Both parts carry RoHS non-compliant status and are subject to identical regulatory classifications (ECCN: EAR99; HTSUS: 8536.10.0020). No compliance or certification differences exist between the two part numbers.

Frequently Asked Questions (FAQ)

Q: Can BK/AGA-5 be used as a direct replacement for AGA-5?

A: Yes. BK/AGA-5 is a parametric equivalent with identical current rating (5 A), voltage rating (125 V AC), fuse type (cartridge, glass), response time (fast blow), package form factor (1AG, 1/4" x 5/8"), breaking capacity (1 kA), and DC cold resistance (0.017 Ohms). Both parts require the same holder and are mechanically and electrically interchangeable.

Q: What is the difference between AGA-5 and BK/AGA-5?

A: The two part numbers are manufactured by the same company (Eaton - Electronics Division) and share identical specifications. The difference is in part number designation only. BK/AGA-5 has higher current inventory availability (1,889 pieces versus 870 pieces).

Q: Are there any compliance or regulatory differences between these parts?

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

Q: What holder is required for these fuses?

A: Both AGA-5 and BK/AGA-5 require a 1AG fuse holder. The 1AG designation specifies the cartridge form factor: 1/4" diameter x 5/8" length (6.35mm x 15.88mm).

Q: What is the breaking capacity of these fuses?

A: Both parts have a breaking capacity of 1 kA at rated voltage (125 V AC).

Q: Are these fuses suitable for DC applications?

A: Both parts are rated for 125 V AC/DC operation. The DC cold resistance is 0.017 Ohms for both part numbers.
