BK/GLN-1/20 Equivalent & Substitute Parts

Part Overview

The BK/GLN-1/20 is a board mount fuse designed for through-hole applications, rated at 50 mA, 125 V AC/DC with fast-blow response characteristics. This component is classified as a cartridge-style, non-standard axial fuse in the GLN series manufactured by Eaton - Electronics Division. The part maintains active product status with 997 units currently in stock as new original inventory.

Substitute parts are identified when equivalent electrical ratings, mechanical dimensions, and mounting configurations are maintained across alternative part numbers. Identifying qualified substitutes ensures design flexibility and supply chain continuity for board mount fuse applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/GLN-1/20 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Current Rating: 50 mA (exact match required)
• Voltage Rating (AC): 125 V (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 50A (exact match required)

Mechanical Parameters:

• Mounting Type: Through Hole (exact match required)
• Fuse Type: Board Mount (Cartridge Style Excluded) (exact match required)
• Package / Case: Cartridge, Non-Standard (Axial) (exact match required)
• Size / Dimension: 0.146" Dia x 0.299" L (3.70mm x 7.60mm) (exact match required)

Environmental & Compliance Parameters:

• Moisture Sensitivity Level (MSL): 1 (Unlimited) (exact match required)
• ECCN: EAR99 (exact match required)
• HTSUS: 8536.10.0040 (exact match required)

Substitute parts must satisfy all electrical, mechanical, and environmental criteria to ensure functional and physical interchangeability in board mount fuse applications.

Parameter Comparison

Engineering Selection Recommendations

BK/GLN-1/20 (Primary Part): The BK/GLN-1/20 maintains active product status with RoHS compliance certification. This part is suitable for applications requiring RoHS-compliant board mount fuses with no specific third-party approval agency requirements. Current inventory of 997 units supports immediate availability.

GFA-1/20 (Substitute Part): The GFA-1/20 is electrically and mechanically equivalent to the BK/GLN-1/20 across all critical parameters. This part carries CSA and UR approval certifications, making it suitable for applications requiring third-party safety agency validation. The GFA-1/20 is classified as RoHS non-compliant; therefore, selection of this substitute should be based on specific application requirements for third-party approvals rather than RoHS compliance mandates. Current inventory of 928 units is available.

Selection Criteria:

• Select BK/GLN-1/20 for RoHS-compliant applications without third-party approval requirements
• Select GFA-1/20 for applications requiring CSA or UR certification with acceptance of RoHS non-compliance status

Both parts are manufactured by Eaton - Electronics Division and maintain identical electrical ratings, response characteristics, and physical dimensions.

Frequently Asked Questions (FAQ)

Q: Are BK/GLN-1/20 and GFA-1/20 electrically interchangeable?

A: Yes. Both parts are rated at 50 mA, 125 V AC/DC with fast-blow response and 50A breaking capacity. Electrical performance is identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.146" Dia x 0.299" L (3.70mm x 7.60mm) and use identical through-hole mounting configurations. Physical interchangeability is confirmed.

Q: What is the difference in RoHS compliance between these parts?

A: The BK/GLN-1/20 is RoHS compliant. The GFA-1/20 is RoHS non-compliant. Selection depends on application requirements for environmental compliance standards.

Q: Does GFA-1/20 have approval certifications that BK/GLN-1/20 lacks?

A: Yes. The GFA-1/20 carries CSA and UR approval certifications. The BK/GLN-1/20 has no listed approval agency certifications. Applications requiring third-party safety validation should specify GFA-1/20.

Q: Can I use GFA-1/20 in a design originally specified for BK/GLN-1/20?

A: Substitution is permissible based on electrical and mechanical equivalence. However, the change in RoHS compliance status and addition of CSA/UR certifications must be evaluated against application requirements and regulatory mandates.

Q: Which part should I select for new designs?

A: Selection is based on specific application requirements. For RoHS-compliant applications without third-party approval mandates, specify BK/GLN-1/20. For applications requiring CSA or UR certification, specify GFA-1/20.
