BK/GMA-V-2A Equivalent & Substitute Parts

Part Overview

The BK/GMA-V-2A is a 2 A, 250 V AC/DC fast-blow glass cartridge fuse with 5mm x 20mm axial through-hole mounting. Manufactured by Eaton - Electronics Division, this component is classified as obsolete product status. Due to its obsolete designation, identifying equivalent and substitute parts from active product lines is necessary to maintain circuit protection functionality in ongoing applications and new designs. Substitute parts must maintain identical electrical ratings and mechanical compatibility while meeting current manufacturing and compliance standards.

Substitute Part Grouping Explanation

Substitute parts for the BK/GMA-V-2A are classified into two categories based on parametric equivalence:

Direct Manufacturer Substitute (Active Product): BK/GMA-V-2-R represents the active production equivalent from Eaton - Electronics Division. This part maintains identical electrical specifications (2 A, 250 V, fast-blow response) and mechanical form factor (5mm x 20mm). The primary difference is product status (active vs. obsolete) and RoHS compliance status. This substitute is the preferred replacement for direct compatibility.

Parametric Equivalents (Alternative Manufacturers): BK/GDB-V-2A, BK/S500-V-2-R, and 0217002.MXEP are parametric equivalents that satisfy the core electrical requirements: 2 A current rating, 250 V voltage rating, fast-blow response, and 5mm x 20mm package dimensions. These parts are functionally interchangeable in circuit protection applications where the specified electrical parameters are the design criteria. Differences in breaking capacity, melting I²t, DC cold resistance, and approval certifications exist and must be evaluated against application requirements.

Substitution Criteria:

• Current Rating: 2 A (mandatory match)
• Voltage Rating: 250 V AC (mandatory match)
• Response Time: Fast Blow (mandatory match)
• Package Dimensions: 5mm x 20mm axial (mandatory match)
• Mounting Type: Through Hole (mandatory match)

Engineering Selection Recommendations

Primary Recommendation: BK/GMA-V-2-R

BK/GMA-V-2-R is the direct active-product substitute from Eaton - Electronics Division. This part maintains identical electrical characteristics (2 A, 250 V, 100 A breaking capacity, 3.1 melting I²t) and mechanical form factor to the obsolete BK/GMA-V-2A. Product status is active, ensuring long-term availability. RoHS compliance status is compliant, meeting current regulatory requirements. Approval certifications include CSA, PSE, and UL. This part is suitable for direct replacement in existing designs without circuit modification.

Secondary Recommendations: BK/GDB-V-2A and BK/S500-V-2-R

Both BK/GDB-V-2A and BK/S500-V-2-R are active Eaton products with identical electrical ratings (2 A, 250 V, fast-blow) and package dimensions. These parts feature reduced breaking capacity (35 A vs. 100 A) and increased melting I²t (4.2 vs. 3.1). BK/S500-V-2-R offers broader approval certifications (BSI, CCC, CSA, cULus, IMQ, SEMKO, VDE) compared to BK/GDB-V-2A (UL, VDE). Selection between these options depends on application breaking capacity requirements and required certification scope.

Alternative Recommendation: 0217002.MXEP

0217002.MXEP is manufactured by Littelfuse Inc. and provides parametric equivalence with identical electrical ratings and package dimensions. This part features the highest melting I²t value (5.73) among all substitutes and the broadest approval certifications (BSI, CE, CCC, CSA, KC, PSE, SEMKO, UR, VDE). Operating temperature range is specified (-55°C to 125°C), providing environmental performance data. Physical dimensions differ slightly (5.80mm x 22.50mm vs. 5.54mm x 21.10mm), requiring verification of mechanical fit in existing footprints. This part is suitable for applications requiring extended certification coverage or specific environmental performance.

Frequently Asked Questions (FAQ)

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

A: Yes. BK/GMA-V-2-R maintains identical electrical specifications (2 A, 250 V, fast-blow response, 100 A breaking capacity) and mechanical form factor (5mm x 20mm axial through-hole). The primary difference is product status (active vs. obsolete) and RoHS compliance. No circuit modification is required.

Q: What is the difference between the 100 A breaking capacity of BK/GMA-V-2-R and the 35 A breaking capacity of BK/GDB-V-2A and BK/S500-V-2-R?

A: Breaking capacity defines the maximum fault current the fuse can safely interrupt without rupturing or creating a hazard. The BK/GMA-V-2-R and BK/GMA-V-2A both have 100 A breaking capacity, while the GDB and S500 series have 35 A. Selection depends on the maximum prospective fault current in the application circuit. If fault current exceeds 35 A, the lower-capacity fuses are not suitable.

Q: Are the physical dimensions of 0217002.MXEP compatible with existing BK/GMA-V-2A footprints?

A: 0217002.MXEP has dimensions of 5.80mm x 22.50mm, compared to 5.54mm x 21.10mm for BK/GMA-V-2A. The slight increase in diameter and length must be verified against mechanical constraints in the specific application. Fuse holders and mounting hardware must accommodate these dimensional differences.

Q: Which substitute part has the broadest approval certifications?

A: 0217002.MXEP (Littelfuse) carries the most comprehensive approval certifications: BSI, CE, CCC, CSA, KC, PSE, SEMKO, UR, and VDE. This part is suitable for applications requiring compliance across multiple international standards and markets.

Q: What does melting I²t represent, and why do the substitute parts have different values?

A: Melting I²t is a thermal characteristic that describes the fuse element's energy absorption capacity before melting. BK/GMA-V-2A and BK/GMA-V-2-R have melting I²t of 3.1, while BK/GDB-V-2A and BK/S500-V-2-R have 4.2, and 0217002.MXEP has 5.73. Higher values indicate greater thermal capacity. Selection depends on circuit inrush current characteristics and desired response time to fault conditions.

Q: Is RoHS compliance a mandatory requirement for selecting a substitute?

A: RoHS compliance status depends on application and regulatory requirements. BK/GMA-V-2-R, BK/GDB-V-2A, BK/S500-V-2-R, and 0217002.MXEP are all RoHS compliant. The original BK/GMA-V-2A is non-compliant. For applications subject to RoHS regulations, compliant substitutes are required.

Q: Can BK/S500-V-2-R be used in applications where BK/GMA-V-2-R is specified?

A: BK/S500-V-2-R maintains identical electrical ratings (2 A, 250 V, fast-blow) and package dimensions. However, breaking capacity is reduced from 100 A to 35 A, and melting I²t increases from 3.1 to 4.2. Substitution is valid only if the application's maximum prospective fault current does not exceed 35 A and the increased thermal capacity is acceptable for the circuit design.
