BK/GDB-V-100MA Equivalent & Substitute Parts

Part Overview

The BK/GDB-V-100MA is a 100 mA, 250 V AC/DC fast-blow glass cartridge fuse with a 5mm x 20mm axial through-hole package manufactured by Eaton - Electronics Division. This component is classified as obsolete product status. Identifying equivalent and substitute parts is necessary to maintain circuit protection functionality in applications where the original GDB series is no longer available from inventory or production channels. Substitute parts must maintain identical electrical ratings, mechanical dimensions, and fuse response characteristics to ensure proper circuit protection without modification to the host equipment.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BK/GDB-V-100MA are classified based on strict electrical and mechanical parameter alignment:

Direct Manufacturer Substitute (Eaton - Electronics Division): The BK/S500-V-100-R maintains identical electrical specifications: 100 mA current rating, 250 V AC voltage rating, fast-blow response, 5mm x 20mm package dimensions, and 35 A breaking capacity. This part is active product status and represents the primary direct substitute from the original manufacturer.

Parametric Equivalent (Eaton - Electronics Division): The BK/GMA-V-100-R shares all critical electrical parameters (100 mA, 250 V AC, fast-blow, 5mm x 20mm, 35 A breaking capacity) and is active product status. Differences exist in melting I²t value (0.0001 vs. 0.003) and DC cold resistance (7.84 Ohms vs. 3.8 Ohms), but these do not affect substitution eligibility within the same manufacturer's product line.

Similar Cross-Manufacturer Part (Littelfuse Inc.): The 0217.100MXEP from Littelfuse Inc. meets all critical electrical requirements (100 mA, 250 V AC, fast-blow, 35 A breaking capacity) and is active product status. Physical dimensions differ slightly (6.00mm x 22.50mm vs. 5.54mm x 21.10mm), and melting I²t is 0.0045 versus 0.003. This part carries broader international certifications (CCC, CE, CSA, K-MARK, SEMKO, UL, VDE) and operates across -55°C to 125°C temperature range.

Engineering Selection Recommendations

Primary Selection: BK/S500-V-100-R This Eaton part is the recommended first choice for direct substitution. It maintains identical electrical parameters, mechanical dimensions, and response characteristics as the obsolete BK/GDB-V-100MA. Active product status ensures availability and supply chain continuity. RoHS compliance supports modern manufacturing and environmental standards.

Secondary Selection: BK/GMA-V-100-R This Eaton part provides an alternative within the same manufacturer ecosystem. Active product status and RoHS compliance are confirmed. Additional certifications (CSA, PSE, UL) provide broader regulatory coverage. Differences in melting I²t and DC cold resistance do not prevent substitution in standard circuit protection applications.

Cross-Manufacturer Alternative: 0217.100MXEP The Littelfuse 0217.100MXEP is suitable when Eaton parts are unavailable. This part meets all critical electrical specifications and is active product status. Comprehensive international certifications (CCC, CE, CSA, K-MARK, SEMKO, UL, VDE) and extended operating temperature range (-55°C to 125°C) support deployment in diverse environments. Physical dimensions are within acceptable tolerance for standard 5mm x 20mm fuse holders.

Frequently Asked Questions (FAQ)

Q: Can BK/S500-V-100-R be used as a direct replacement for BK/GDB-V-100MA? A: Yes. The BK/S500-V-100-R is a direct substitute. Both parts share identical current rating (100 mA), voltage rating (250 V AC), fuse type (cartridge glass), response time (fast-blow), package dimensions (5mm x 20mm), and breaking capacity (35 A). The S500 series is active product status, ensuring availability.

Q: What is the difference between BK/GMA-V-100-R and BK/S500-V-100-R? A: Both parts are functionally equivalent for circuit protection purposes. The GMA series has a lower melting I²t value (0.0001 vs. 0.003) and higher DC cold resistance (7.84 Ohms vs. 3.8 Ohms). Both are Eaton products with active status and RoHS compliance. Selection between them depends on specific application requirements and inventory availability.

Q: Can the Littelfuse 0217.100MXEP replace the Eaton BK/GDB-V-100MA? A: Yes. The 0217.100MXEP meets all critical electrical parameters: 100 mA current, 250 V AC voltage, fast-blow response, 35 A breaking capacity, and 5mm x 20mm package. Physical dimensions are 6.00mm x 22.50mm, which is compatible with standard fuse holders designed for 5mm x 20mm cartridges. This part is active product status with comprehensive international certifications.

Q: Are there any mechanical compatibility concerns with these substitutes? A: All substitute parts use the 5mm x 20mm axial through-hole package format. The Littelfuse 0217.100MXEP has slightly larger physical dimensions (6.00mm x 22.50mm vs. 5.54mm x 21.10mm), but this difference is within acceptable tolerance for standard fuse holder designs. No mechanical modification is required.

Q: Which substitute part has the broadest regulatory certifications? A: The Littelfuse 0217.100MXEP carries the most comprehensive certifications: CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE. This makes it suitable for applications requiring multi-regional compliance. The Eaton BK/GMA-V-100-R includes CSA, PSE, and UL certifications.

Q: What is the significance of the melting I²t parameter in these fuses? A: Melting I²t indicates the thermal energy required to melt the fuse element. The BK/GDB-V-100MA and BK/S500-V-100-R both have 0.003 I²t, while the BK/GMA-V-100-R has 0.0001 I²t, and the 0217.100MXEP has 0.0045 I²t. These variations reflect different fuse element designs but do not prevent substitution in standard 100 mA, 250 V applications.

Q: Is RoHS compliance required for my application? A: All active substitute parts (BK/S500-V-100-R, BK/GMA-V-100-R, and 0217.100MXEP) are RoHS compliant. The original BK/GDB-V-100MA does not specify RoHS status due to its obsolete classification. If RoHS compliance is mandatory, any of the three active substitutes are acceptable.
