Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BK/GMC-V-3A are classified based on electrical and mechanical compatibility within the following criteria:

Direct Substitutes maintain identical electrical specifications: 3 A current rating, 250 V AC voltage rating, medium blow response, 5mm x 20mm package, and through-hole mounting. These parts are interchangeable in circuits designed for the original specification.

Compatible Substitutes share the same current rating (3 A), package dimensions (5mm x 20mm), fuse type (glass cartridge), and response time (medium blow), but operate at different voltage ratings. These parts are suitable for applications where the circuit voltage is lower than or equal to the substitute part's voltage rating.

The key parameters determining substitution eligibility are:

• Current Rating (Amps): 3 A
• Fuse Type: Cartridge, Glass
• Package / Case: 5mm x 20mm (Axial)
• Response Time: Medium Blow
• Mounting Type: Through Hole

Parameter Comparison

Engineering Selection Recommendations

BK/GMC-V-3-R is the primary substitute for BK/GMC-V-3A. Both parts are manufactured by Eaton - Electronics Division and share identical electrical and mechanical specifications. The BK/GMC-V-3-R is currently in active production status, whereas the original part is obsolete. The BK/GMC-V-3-R carries ROHS3 compliance, addressing environmental regulatory requirements. Both parts maintain the same approval certifications (CSA, KC-MARK, MITI, UL) and identical performance characteristics including 100 A breaking capacity and 19 melting I²t.

0233003.MXEP is a compatible substitute manufactured by Littelfuse Inc. This part maintains the same 3 A current rating, 5mm x 20mm package, medium blow response, and through-hole mounting. However, the voltage rating is 125 V AC, which is lower than the original 250 V specification. This part is suitable only for applications where the circuit voltage does not exceed 125 V AC. The 0233003.MXEP offers higher breaking capacity (10 kA) and different thermal characteristics (26.24 melting I²t, 0.0431 Ohms DC cold resistance). This part carries CE, CSA, KC, PSE, and UL approvals with ROHS3 compliance and an operating temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can BK/GMC-V-3-R directly replace BK/GMC-V-3A in all applications?

A: Yes. The BK/GMC-V-3-R is a direct substitute with identical electrical ratings (3 A, 250 V AC), response time (medium blow), package dimensions (5mm x 20mm), and mounting type (through hole). Both parts carry the same international approvals and breaking capacity specifications.

Q: What is the key difference between BK/GMC-V-3-R and 0233003.MXEP?

A: The primary difference is voltage rating. BK/GMC-V-3-R is rated for 250 V AC, while 0233003.MXEP is rated for 125 V AC. The 0233003.MXEP also has different thermal characteristics (higher melting I²t and DC cold resistance) and higher breaking capacity (10 kA versus 100 A). Both maintain the same 3 A current rating and 5mm x 20mm package.

Q: Can 0233003.MXEP be used in a 250 V circuit?

A: No. The 0233003.MXEP is rated for 125 V AC maximum. Using this part in a 250 V circuit exceeds its voltage rating and violates safe operating conditions.

Q: Are there RoHS compliance differences between these parts?

A: Yes. The original BK/GMC-V-3A is RoHS non-compliant. Both substitute parts, BK/GMC-V-3-R and 0233003.MXEP, are ROHS3 compliant, meeting current environmental regulatory requirements.

Q: What are the approval certifications for each part?

A: BK/GMC-V-3A and BK/GMC-V-3-R share identical approvals: CSA, KC-MARK, MITI, and UL. The 0233003.MXEP carries CE, CSA, KC, PSE, and UL approvals, providing broader international certification coverage.

Q: How do the thermal characteristics differ between these fuses?

A: The BK/GMC-V-3A and BK/GMC-V-3-R both have a melting I²t of 19 and DC cold resistance of 0.026 Ohms. The 0233003.MXEP has a higher melting I²t of 26.24 and higher DC cold resistance of 0.0431 Ohms, indicating different thermal response characteristics.
