Equivalent & Substitute Parts for BK/GDA-V-2A

Part Overview

The BK/GDA-V-2A is a 2A ceramic cartridge fuse rated for 250V AC/DC operation, designed for through-hole mounting in 5mm x 20mm form factor. This fast-blow fuse is manufactured by Eaton - Electronics Division and maintains active product status. Substitute parts are identified when identical electrical and mechanical parameters are required but alternative sourcing, packaging, or compliance profiles are necessary for procurement, inventory management, or regulatory requirements.

Substitute Part Grouping Explanation

Substitution of the BK/GDA-V-2A is permissible when the following electrical and mechanical parameters remain identical:

• Current Rating: 2 A
• Voltage Rating (AC): 250 V
• Fuse Type: Cartridge, Ceramic
• Response Time: Fast Blow
• Package / Case: 5mm x 20mm (Axial)
• Mounting Type: Through Hole
• Breaking Capacity @ Rated Voltage: 1.5 kA
• Melting I²t: 2
• DC Cold Resistance: 0.073 Ohms
• Physical Dimensions: 0.218" Dia x 0.831" L (5.54mm x 21.10mm)

The BK/S501-V-2-R qualifies as a parametric equivalent substitute based on matching all critical electrical and mechanical specifications. Differences in series designation, packaging format, and regulatory certifications do not affect functional interchangeability in applications requiring these exact parameters.

Engineering Selection Recommendations

Both the BK/GDA-V-2A and BK/S501-V-2-R are active products from Eaton - Electronics Division with identical electrical and mechanical specifications. Selection between these parts should be based on the following criteria:

BK/GDA-V-2A (GDA Series): Select this part when RoHS non-compliant status is acceptable for the application. Current inventory: 1006 pieces.

BK/S501-V-2-R (S501 Series): Select this part when RoHS compliance is required. This variant carries broader regulatory certifications including BSI, cULus, MITI/JET, and VDE in addition to the certifications held by the GDA series. Current inventory: 752 pieces.

Both parts satisfy identical functional requirements for 2A, 250V AC/DC ceramic cartridge fuse applications with fast-blow response characteristics and 1.5 kA breaking capacity.

Frequently Asked Questions (FAQ)

Q: Can BK/S501-V-2-R be used as a direct replacement for BK/GDA-V-2A?

A: Yes. Both parts are parametric equivalents with identical current rating (2A), voltage rating (250V AC), fuse type (ceramic cartridge), response time (fast blow), package dimensions (5mm x 20mm), and electrical characteristics (1.5 kA breaking capacity, 0.073 Ohms DC cold resistance). Physical and electrical interchangeability is confirmed.

Q: What is the difference between the GDA and S501 series?

A: The GDA and S501 series are distinct product lines from Eaton with identical electrical and mechanical specifications for this 2A rating. The primary differences are series designation, packaging format (GDA uses standard packaging; S501 uses bulk packaging), and regulatory certifications. The S501 series carries additional certifications including RoHS compliance.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance status reflects manufacturing and material composition standards but does not alter the electrical performance, current rating, voltage rating, or response characteristics of the fuse.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.218" diameter x 0.831" length (5.54mm x 21.10mm) and are designed for identical through-hole mounting in 5mm x 20mm fuse holders.

Q: Which certifications does each part hold?

A: BK/GDA-V-2A holds CCC, CSA, IMQ, SEMKO, and UR certifications. BK/S501-V-2-R holds BSI, CCC, CSA, cULus, IMQ, MITI/JET, SEMKO, and VDE certifications. Both parts meet the core safety standards required for ceramic cartridge fuses.
