GDA-80MA Ceramic Fuse Equivalent & Substitute Parts

Part Overview

The GDA-80MA is an 80 mA ceramic fuse cartridge rated for 250 V AC/DC operation in a 5mm x 20mm form factor. This fast-blow fuse requires a compatible holder for installation and is designed for circuit protection applications requiring rapid response to overcurrent conditions. The part is currently active in production with 820 pieces in stock. Equivalent substitute parts are identified based on matching electrical ratings, mechanical dimensions, and performance characteristics to ensure direct functional replacement in existing designs and applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GDA-80MA are qualified based on the following critical parameters that must match or exceed the main part specifications:

Mandatory Matching Parameters:

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

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the GDA-80MA in applications designed for this fuse specification.

Parameter Comparison

Engineering Selection Recommendations

GDA-80MA (Eaton - Electronics Division) Primary part with active production status. Holds CSA and UR approvals. Suitable for applications requiring these specific certifications. Current inventory of 820 pieces supports immediate availability.

BK1/S501-80-R (Eaton - Electronics Division) Parametric equivalent from the same manufacturer. Holds CSA and cULus approvals, providing broader certification coverage than the main part. RoHS Compliant with MSL rating of 1 (Unlimited). Higher inventory availability at 1078 pieces. Identical electrical performance with matching melting I²t and DC cold resistance values.

0216.080HXP (Littelfuse Inc.) Parametric equivalent from alternative manufacturer. Holds expanded certification portfolio including CCC, CE, CSA, SEMKO, UR, and VDE. ROHS3 Compliant with REACH Unaffected status. Operating temperature range specified as -55°C ~ 125°C. Lower DC cold resistance (7.885 Ohms) and slightly lower melting I²t (0.00084) compared to Eaton parts. Suitable for applications requiring broader international certifications or extended temperature operation.

Frequently Asked Questions (FAQ)

Q: Can BK1/S501-80-R be used as a direct replacement for GDA-80MA? A: Yes. Both parts are 80 mA ceramic fuses with 250 V AC rating in 5mm x 20mm form factor, identical fast-blow response, and matching 1.5 kA breaking capacity. Both require the same holder type. Electrical performance parameters are identical.

Q: What is the difference between the Eaton and Littelfuse substitute options? A: All three parts meet the same core electrical and mechanical specifications. The primary differences are manufacturer certifications, DC cold resistance values, and operating temperature range. The Littelfuse 0216.080HXP offers broader international certifications and specified temperature operation from -55°C to 125°C.

Q: Are there compatibility concerns when switching between these substitute parts? A: No compatibility concerns exist for the electrical or mechanical interface. All three parts use identical 5mm x 20mm cartridge dimensions and require the same holder type. Selection should be based on certification requirements, temperature operating range needs, and availability.

Q: Does the difference in DC cold resistance affect circuit performance? A: DC cold resistance values are provided for reference. The GDA-80MA and BK1/S501-80-R both specify 27.9 Ohms, while the 0216.080HXP specifies 7.885 Ohms. For 80 mA fuses, these resistance values have minimal impact on typical circuit operation. Selection should prioritize matching current rating, voltage rating, and breaking capacity.

Q: Which substitute part should be selected for international applications? A: The 0216.080HXP (Littelfuse) offers the broadest certification coverage with CCC, CE, CSA, SEMKO, UR, and VDE approvals, making it suitable for applications requiring compliance across multiple international markets.

Q: Are all substitute parts currently in stock? A: Yes. GDA-80MA: 820 pieces; BK1/S501-80-R: 1078 pieces; 0216.080HXP: 775 pieces. All are listed as new original stock.
