GDB-10A Glass Cartridge Fuse 10A 250VAC 5x20mm Equivalent & Substitute Parts

Part Overview

The GDB-10A is a fast-blow glass cartridge fuse manufactured by Eaton - Electronics Division, rated for 10 amperes at 250 volts AC/DC. This component requires a fuse holder for installation and is designed for circuit protection applications requiring rapid response to overcurrent conditions. The part maintains active product status with 1055 units in current inventory. Equivalent and substitute parts are identified based on matching electrical specifications, mechanical dimensions, and approval certifications to ensure direct functional interchangeability in protected circuit applications.

Substitute Part Grouping Explanation

Substitute parts for the GDB-10A are qualified based on strict equivalence across the following critical parameters: current rating (10 A), voltage rating (250 V AC), fuse type (cartridge glass), response time (fast blow), physical dimensions (5mm x 20mm), and breaking capacity (100A). All identified substitutes maintain identical electrical performance characteristics and mechanical compatibility with standard 5x20mm fuse holders. Substitution is valid across manufacturers when these parameters align exactly. Variations in approval agencies, RoHS compliance status, and melting I²t values do not affect functional interchangeability for the specified circuit protection application.

Engineering Selection Recommendations

All listed substitute parts are qualified for direct replacement of the GDB-10A based on identical electrical and mechanical specifications. Selection among substitutes should be based on the following criteria:

Eaton Series Parts (BK/GDB-10A, BK/S500-10-R, BK1/S500-10-R, S500-10-R): These parts maintain manufacturer continuity with the original GDB-10A and carry expanded approval certifications including UL, CSA, and cULus. The S500 series variants offer broader international compliance (BSI, SEMKO) suitable for applications requiring multi-region certification. Inventory availability ranges from 885 to 2959 units.

SCHURTER 0034.1526: This substitute provides the highest current inventory level (10455 units) and includes operating temperature specification (-55°C to 125°C). Approval agencies include cURus, PSE/JET, and VDE, supporting applications in Asian and European markets.

Littelfuse 217 Series (0217010.HXP, 0217010.MXBP, 0217010.MXP, 0217010.TXP, 0217010.VXP): These parts offer the largest combined inventory (29425 units) with consistent DC cold resistance of 0.0063 ohms and operating temperature range of -55°C to 125°C. Approval certifications include CE, PSE, and VDE with regional variants (K-MARK, KC). The 0217010.MXP variant has the highest individual inventory (17281 units).

Selection priority should follow: (1) application-specific approval requirements, (2) inventory availability, (3) operating temperature requirements if specified in the application.

Frequently Asked Questions (FAQ)

Q: Can all listed substitute parts replace the GDB-10A in any application?

A: Yes, all listed parts are parametrically equivalent across the critical specifications: 10A current rating, 250V AC voltage rating, fast-blow response, 5x20mm physical dimensions, and 100A breaking capacity. They are mechanically and electrically interchangeable in standard 5x20mm fuse holders.

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

A: Both series are manufactured by Eaton and meet identical electrical specifications. The S500 series variants (BK/S500-10-R, BK1/S500-10-R, S500-10-R) carry additional international approvals (BSI, CSA, cULus, SEMKO) compared to the GDB series, making them suitable for applications requiring broader certification coverage.

Q: Are there differences in DC cold resistance between the GDB-10A and Littelfuse substitutes?

A: The GDB-10A specifies 0.008 ohms DC cold resistance, while Littelfuse 217 series parts specify 0.0063 ohms. Both values fall within acceptable ranges for 10A cartridge fuses and do not affect functional interchangeability. The lower resistance in Littelfuse parts represents improved electrical efficiency.

Q: Which substitute has the best inventory availability?

A: The Littelfuse 0217010.MXP has the highest individual inventory at 17281 units. Combined Littelfuse 217 series inventory totals 29425 units. SCHURTER 0034.1526 offers 10455 units as a single alternative source.

Q: Do operating temperature specifications affect substitution?

A: The GDB-10A does not specify an operating temperature range. SCHURTER 0034.1526 and all Littelfuse 217 series parts specify -55°C to 125°C operating range. This extended specification does not prevent substitution but indicates enhanced performance capability in temperature-sensitive applications.

Q: What approval agencies are most relevant for international applications?

A: VDE approval is common across all substitutes, supporting European applications. For North American markets, UL and cULus certifications are present in Eaton variants and Littelfuse parts. For Asian markets, PSE and K-MARK certifications are available in Littelfuse variants. Select based on target market requirements.

Q: Can I mix different substitute brands in the same equipment?

A: Yes. All substitutes meet identical electrical and mechanical specifications. Mixing brands within the same equipment does not affect circuit protection performance. However, for consistency in maintenance and inventory management, using a single brand source is recommended.
