BK/AGC-V-9 Equivalent & Substitute Parts

Part Overview

The BK/AGC-V-9 is a 9 A, 250 V AC/DC fast-blow glass cartridge fuse with 3AB/3AG form factor and 1/4" x 1-1/4" axial dimensions. This through-hole mounted fuse is designed for circuit protection applications requiring fast response characteristics and is currently in active production status. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and continuity of supply across manufacturing and maintenance operations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK/AGC-V-9 is determined by strict equivalence across the following critical parameters:

• Current Rating: 9 A (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Form Factor: 3AB, 3AG (exact match required)
• Physical Dimensions: 1/4" x 1-1/4" axial (exact match required)
• Response Characteristic: Fast Blow (exact match required)
• Mounting Configuration: Through Hole (exact match required)
• Approval Certifications: CSA, UL (must be maintained)

The substitute part BK/AGC-V-9-R meets all electrical and mechanical parameters identical to the main part. The primary distinction between these parts is packaging configuration and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both BK/AGC-V-9 and BK/AGC-V-9-R are active production parts manufactured by Eaton - Electronics Division and carry identical CSA and UL certifications. Selection between these parts is based on the following criteria:

BK/AGC-V-9: Select this part number when standard packaging is required and RoHS compliance is not a design constraint.

BK/AGC-V-9-R: Select this part number when bulk packaging is preferred for high-volume procurement or when RoHS compliance is mandated by design specifications or regulatory requirements.

Both parts are electrically and mechanically interchangeable within circuits designed for 9 A, 250 V AC/DC fast-blow fuse protection. The choice between these substitutes does not affect circuit performance, thermal characteristics, or protection response.

Frequently Asked Questions (FAQ)

Q: Are BK/AGC-V-9 and BK/AGC-V-9-R electrically identical?

A: Yes. Both parts have identical electrical specifications including 9 A current rating, 250 V voltage rating, 395.28 melting I²t, 0.009 Ohms DC cold resistance, and 200 A breaking capacity at rated voltage.

Q: What is the difference between these two part numbers?

A: The primary differences are packaging configuration (standard versus bulk) and RoHS compliance status. BK/AGC-V-9-R is RoHS compliant, while BK/AGC-V-9 is RoHS non-compliant. All electrical and mechanical parameters are identical.

Q: Can BK/AGC-V-9-R be used as a direct replacement for BK/AGC-V-9 in existing designs?

A: Yes. Both parts share identical form factor (3AB, 3AG), dimensions (1/4" x 1-1/4"), mounting type (through hole), and response characteristics (fast blow). They are mechanically and electrically interchangeable.

Q: Do both parts have the same certifications?

A: Yes. Both BK/AGC-V-9 and BK/AGC-V-9-R carry CSA and UL approvals and operate across the same temperature range (-55°C to 125°C).

Q: Which part should be selected for new designs?

A: Selection depends on RoHS compliance requirements. For designs requiring RoHS compliance, specify BK/AGC-V-9-R. For designs without RoHS constraints, either part is acceptable based on packaging preference.

Q: Are there inventory differences between these parts?

A: Yes. BK/AGC-V-9 has 776 pieces in stock, while BK/AGC-V-9-R has 718 pieces in stock. Availability should be verified at time of procurement.
