Equivalent & Substitute Parts for BK/GDA-80MA Ceramic Fuse

Part Overview

The BK/GDA-80MA is an 80 mA ceramic fuse cartridge rated for 250 V AC/DC operation in a 5mm x 20mm form factor. Manufactured by Eaton - Electronics Division, this fast-blow fuse is designed for applications requiring overcurrent protection with a breaking capacity of 1.5 kA. The part is currently active in production with 675 units in stock. Substitute parts may be required due to supply chain constraints, regional availability, or specific compliance certifications needed for particular markets or applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/GDA-80MA is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 80 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Package / Case: 5mm x 20mm (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 1.5 kA (exact match required)
• Mounting Type: Requires Holder (exact match required)

Both identified substitute parts meet all mandatory matching parameters. Differences in secondary characteristics such as DC cold resistance, melting I²t values, approval agencies, and operating temperature ranges do not disqualify substitution when primary electrical and mechanical specifications are identical.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products with current manufacturing status and full RoHS compliance. Selection between BK/GDA-80MA, BK1/S501-80-R, and 0216.080HXP should be based on the following factors:

Eaton BK/GDA-80MA (Primary Part): Suitable for applications requiring CSA and UL certifications. Recommended as the primary choice when original part specifications are preferred.

Eaton BK1/S501-80-R (Parametric Equivalent): Functionally identical to the primary part with expanded certification to include cULus. Higher inventory availability (1078 units) supports supply chain continuity. Recommended when Eaton sourcing is required and cULus certification is beneficial.

Littelfuse 0216.080HXP (Direct Manufacturer Alternative): Provides broader international certification coverage including CCC, CE, SEMKO, UR, and VDE in addition to CSA. Suitable for applications requiring multi-regional compliance. Operating temperature range specified as -55°C ~ 125°C. Inventory of 775 units supports availability. Recommended for applications with international distribution or specific regional certification requirements.

Frequently Asked Questions (FAQ)

Q: Can BK1/S501-80-R be used as a direct replacement for BK/GDA-80MA?

A: Yes. Both parts are manufactured by Eaton and share identical electrical and mechanical specifications: 80 mA current rating, 250 V AC voltage rating, 5mm x 20mm package, fast-blow response, and 1.5 kA breaking capacity. The primary difference is the series designation (GDA versus S501) and certification scope (UL versus cULus).

Q: What are the differences between the Eaton and Littelfuse options?

A: All three parts meet identical core electrical and mechanical requirements. The Littelfuse 0216.080HXP differs in manufacturer, approval agencies (broader international certifications), specified operating temperature range (-55°C ~ 125°C), and secondary electrical characteristics (DC cold resistance and melting I²t). These differences do not affect substitution eligibility for standard 80 mA, 250 V AC/DC applications.

Q: Are there any compatibility concerns with fuse holders?

A: No. All three parts use the identical 5mm x 20mm cartridge form factor and require a standard fuse holder. Physical and electrical compatibility with existing holder hardware is assured.

Q: Which part should be selected for international applications?

A: The Littelfuse 0216.080HXP offers the broadest certification coverage with CCC, CE, SEMKO, UR, and VDE approvals, making it suitable for multi-regional deployment. Eaton parts carry CSA and UL certifications appropriate for North American markets.

Q: Does RoHS compliance differ between the three parts?

A: All parts are RoHS compliant. BK/GDA-80MA and BK1/S501-80-R are RoHS Compliant; 0216.080HXP is ROHS3 Compliant, representing the current RoHS standard revision.
