Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Matching Parameters:

• Current Rating: 80 mA
• Voltage Rating (AC): 250 V
• Fuse Type: Cartridge, Glass
• Response Time: Fast Blow
• Package / Case: 5mm x 20mm
• Breaking Capacity @ Rated Voltage: 35A
• Mounting Type: Requires Holder

All identified substitute parts match these parameters exactly. Variations in secondary characteristics such as melting I²t, DC cold resistance, RoHS compliance status, and operating temperature ranges do not disqualify substitution but are documented for engineering reference. Substitute parts are sourced from Eaton - Electronics Division (GDB and S500 series) and cross-manufacturer suppliers including Littelfuse Inc. and SCHURTER Inc.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and are suitable for direct replacement in applications requiring an 80 mA, 250 V AC/DC fast-blow glass cartridge fuse in a 5x20mm form factor.

Eaton - Electronics Division Parts (GDB-80MA, BK/GDB-80MA, BK/S500-80-R, S500-80-R): These parts are manufactured by the original equipment supplier and provide continuity with existing supply chains. BK/GDB-80MA and BK/S500-80-R variants include RoHS3 compliance certification. All Eaton variants carry identical electrical specifications and breaking capacity.

SCHURTER Inc. 0034.1531: This part carries multiple approval agencies (CCC, cURus, VDE) and operates across the temperature range -55°C to 125°C. Melting I²t is 0.00102, which is within acceptable tolerance of the main part specification.

Littelfuse Inc. 0217.080MXP: This part carries the broadest approval agency coverage (CCC, CE, CSA, K-MARK, SEMKO, UL, VDE) and operates across -55°C to 125°C. Melting I²t is 0.00083 and DC cold resistance is 7.89 Ohms. RoHS3 and REACH compliance are confirmed.

Selection among these parts should be based on supply availability, existing qualification history, and specific approval agency requirements for the end application.

Frequently Asked Questions (FAQ)

Q: Can BK/GDB-80MA be used as a direct replacement for GDB-80MA?

A: Yes. Both parts are manufactured by Eaton - Electronics Division, carry identical electrical ratings (80 mA, 250 V AC/DC), response time (fast blow), package dimensions (5x20mm), and breaking capacity (35A). The BK designation indicates RoHS3 compliance. Inventory availability for BK/GDB-80MA is 1030 units.

Q: What is the difference between the S500 series and GDB series fuses?

A: Both series are manufactured by Eaton - Electronics Division and meet identical electrical and mechanical specifications for this 80 mA, 250 V application. The S500 series variants (BK/S500-80-R and S500-80-R) carry RoHS3 compliance. Series designation reflects internal product line organization but does not affect functional compatibility.

Q: Are cross-manufacturer substitutes (Littelfuse, SCHURTER) fully compatible?

A: Yes. The Littelfuse 0217.080MXP and SCHURTER 0034.1531 parts match all mandatory electrical parameters: 80 mA current rating, 250 V AC voltage rating, fast-blow response, 5x20mm package, and 35A breaking capacity. Both parts are Active status. Littelfuse carries broader approval agency certifications (UL, CE, CSA, VDE, K-MARK, SEMKO, CCC). SCHURTER carries CCC, cURus, and VDE certifications.

Q: Does melting I²t variation affect substitution suitability?

A: Melting I²t values are provided for engineering reference. The main part GDB-80MA specifies 0.0012. Substitute parts show minor variations: 0.00102 (SCHURTER), 0.00083 (Littelfuse), and 0.0012 (Eaton variants). These variations remain within the functional tolerance band for 80 mA fast-blow cartridge fuses and do not disqualify substitution.

Q: What does "Requires Holder" mean for mounting type?

A: All listed parts are cartridge fuses designed for use in dedicated 5x20mm fuse holders. The fuse itself is not soldered or mounted directly to a PCB. A compatible fuse holder rated for 5x20mm cartridges and 250 V AC minimum is required for installation.

Q: Which substitute part has the best approval agency coverage?

A: Littelfuse 0217.080MXP carries the most comprehensive approval certifications: CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE. This part is suitable for applications requiring multi-regional compliance documentation.

Q: Can I use these fuses in DC applications?

A: All parts are rated for 250 V AC/DC operation. The voltage rating applies to both AC and DC circuits. However, fast-blow fuses are optimized for AC applications. Consult application-specific requirements for DC circuit protection.
