BK/GMD-V-3-R Equivalent & Substitute Parts

Part Overview

The BK/GMD-V-3-R is a 3 A, 250 V AC/DC slow-blow glass cartridge fuse manufactured by Eaton - Electronics Division. This through-hole fuse is designed for 5mm x 20mm axial mounting applications and is currently in active production status. The part is ROHS3 compliant and carries multiple international approvals including CSA, PSE/JET, and UL certification. Equivalent substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part becomes unavailable or when design requirements permit cross-manufacturer sourcing.

Substitute Part Grouping Explanation

Substitution eligibility for the BK/GMD-V-3-R is determined by strict equivalence across the following critical parameters:

• Current Rating: 3 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 5mm x 20mm (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity @ Rated Voltage: 100 A (exact match required)

All identified substitute parts meet these criteria. Substitute parts must also maintain active product status and ROHS3 compliance. The following parts are qualified equivalents:

• 0239003.HXEP (Littelfuse Inc., Series 239)
• 5TTP 3-R (Bel Fuse Inc., Series 5TTP)

Parameter Comparison

Engineering Selection Recommendations

All three parts—BK/GMD-V-3-R, 0239003.HXEP, and 5TTP 3-R—are functionally equivalent for applications requiring a 3 A, 250 V AC/DC slow-blow glass cartridge fuse in 5mm x 20mm axial through-hole configuration. Selection among these parts may be based on:

Certification Coverage: The BK/GMD-V-3-R carries CSA, PSE/JET, and UL approvals. The 0239003.HXEP carries CE, CSA, KC, PSE, and UL approvals. The 5TTP 3-R carries CE, CSA, cULus, and PSE approvals. Design requirements specifying particular regional certifications should guide part selection.

Inventory Availability: Current stock levels are 758 pcs (BK/GMD-V-3-R), 1014 pcs (0239003.HXEP), and 1412 pcs (5TTP 3-R).

Operating Temperature Range: The BK/GMD-V-3-R does not specify an operating temperature range. The 0239003.HXEP and 5TTP 3-R both specify -55°C ~ 125°C operating temperature range.

Physical Dimensions: All three parts are mechanically compatible within the 5mm x 20mm axial package specification. Dimensional variations are within acceptable tolerance for standard through-hole fuse holders.

Frequently Asked Questions (FAQ)

Q: Can 0239003.HXEP be used as a direct replacement for BK/GMD-V-3-R?

A: Yes. Both parts meet identical electrical specifications: 3 A, 250 V AC/DC, slow-blow response, 100 A breaking capacity, and 5mm x 20mm axial through-hole package. Physical dimensions are within acceptable tolerance for standard fuse holders.

Q: What is the difference in melting I²t values among the three parts?

A: Melting I²t values are 145 (BK/GMD-V-3-R), 129.51 (0239003.HXEP), and 55.6 (5TTP 3-R). These variations reflect different internal element designs while maintaining the same 3 A current rating and slow-blow response classification. All three parts are qualified equivalents for the specified application.

Q: Are there any compliance differences between the substitute parts?

A: All three parts are ROHS3 compliant and carry active product status. Certification differences exist: BK/GMD-V-3-R includes PSE/JET approval; 0239003.HXEP includes KC approval; 5TTP 3-R includes cULus approval. Select based on required regional certifications for your application.

Q: Do the DC cold resistance differences affect substitution?

A: DC cold resistance values are 0.0655 Ohms (BK/GMD-V-3-R), 0.04877 Ohms (0239003.HXEP), and 0.043 Ohms (5TTP 3-R). These variations are inherent to different manufacturing designs. All values are within acceptable ranges for 3 A cartridge fuses and do not prevent substitution.

Q: What is the operating temperature range for BK/GMD-V-3-R?

A: The operating temperature range for BK/GMD-V-3-R is not specified in the provided data. The substitute parts 0239003.HXEP and 5TTP 3-R both specify -55°C ~ 125°C operating temperature range.

Q: Are all three parts available in bulk packaging?

A: Yes. All three parts are supplied in bulk packaging with current inventory: 758 pcs (BK/GMD-V-3-R), 1014 pcs (0239003.HXEP), and 1412 pcs (5TTP 3-R).
