BK/GMD-V-200-R Equivalent & Substitute Parts

Part Overview

The BK/GMD-V-200-R is a 200 mA, 250 V AC/DC slow-blow glass cartridge fuse manufactured by Eaton - Electronics Division. This through-hole component features a 5mm x 20mm axial package and is designed for circuit protection applications requiring controlled response characteristics. The part maintains active product status with 810 units in current inventory. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to supply constraints, design standardization, or component lifecycle management.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/GMD-V-200-R is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Current Rating: 200 mA (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: 35 A (exact match required)

Compliance Parameters:

• RoHS3 Compliant status (required for regulatory alignment)

The substitute part 0218.200MXEP manufactured by Littelfuse Inc. meets all critical matching parameters and maintains equivalent regulatory compliance. Physical dimensions show minor variation (0.228" Dia x 0.886" L versus 0.218" Dia x 0.831" L) within acceptable mechanical tolerances for standard fuse holders. Electrical characteristics including melting I²t and DC cold resistance differ but remain within the functional envelope for this component category.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The BK/GMD-V-200-R remains the preferred component when supply is available. Current inventory of 810 units supports standard procurement cycles.

Substitute Part Selection: The 0218.200MXEP is functionally equivalent for direct replacement in applications requiring a 200 mA, 250 V AC/DC slow-blow glass cartridge fuse with 5mm x 20mm axial package. Selection of this substitute is appropriate when:

• BK/GMD-V-200-R supply is unavailable or constrained
• Design standardization across multiple fuse manufacturers is acceptable
• Circuit protection requirements are met by equivalent electrical parameters
• Regulatory compliance with CSA and UL certifications is required

The 0218.200MXEP carries expanded approval certifications (CCC, CE, K-MARK, SEMKO, VDE) in addition to CSA and UL, providing broader geographic compliance coverage. Inventory availability of 1200 units supports extended procurement requirements.

Compatibility Considerations: Both parts are rated for identical voltage and current specifications with matching breaking capacity. Physical dimension variation (approximately 0.01" diameter and 0.055" length difference) is within standard mechanical tolerances for fuse holders designed to accommodate 5mm x 20mm cartridge fuses. No circuit board redesign or holder modification is required for substitution.

Frequently Asked Questions (FAQ)

Q: Can the 0218.200MXEP replace the BK/GMD-V-200-R in existing designs?

A: Yes. Both components share identical electrical ratings (200 mA, 250 V AC/DC), fuse type (cartridge, glass), response characteristic (slow blow), and package specification (5mm x 20mm axial). Physical dimensions fall within standard mechanical tolerances for fuse holders. No design modification is required.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Eaton versus Littelfuse), series designation (GMD versus 218), DC cold resistance (5.19 Ohms versus 1.6 Ohms), and melting I²t (0.2 versus 0.341). These differences do not affect substitutability for standard circuit protection applications. The 0218.200MXEP carries additional regulatory approvals (CCC, CE, K-MARK, SEMKO, VDE).

Q: Are there any voltage or current rating differences?

A: No. Both parts are rated for 200 mA at 250 V AC/DC with identical 35 A breaking capacity at rated voltage. Substitution does not alter circuit protection performance.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both the BK/GMD-V-200-R and 0218.200MXEP are ROHS3 compliant, meeting current environmental and material restriction standards.

Q: What is the significance of the different DC cold resistance values?

A: DC cold resistance (5.19 Ohms versus 1.6 Ohms) reflects internal construction differences between manufacturers but does not affect the fuse's primary function as a circuit protection device. Both values are within acceptable ranges for this component category and do not impact circuit operation.

Q: Can I use these parts interchangeably in production?

A: Yes, provided your design specifications require a 200 mA, 250 V AC/DC slow-blow glass cartridge fuse with 5mm x 20mm axial package and through-hole mounting. Both parts meet these criteria and carry appropriate regulatory certifications (CSA, UL). Verify that your fuse holder accommodates the minor physical dimension variation.

Q: Which part should I specify for new designs?

A: Either part is acceptable for new designs meeting the stated electrical and mechanical requirements. The BK/GMD-V-200-R offers established supply through Eaton. The 0218.200MXEP provides expanded regulatory coverage and alternative sourcing through Littelfuse. Selection may depend on preferred supplier relationships, inventory availability, and geographic compliance requirements.
