Equivalent & Substitute Parts for 5MT 200

Part Overview

The 5MT 200 is a 200 mA, 250 V AC/DC glass cartridge fuse manufactured by Bel Fuse Inc. in a 5mm x 20mm package format. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. The fuse requires a holder for installation and provides medium-blow response characteristics suitable for general-purpose circuit protection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5MT 200 is determined by strict alignment with the following electrical and mechanical parameters:

• Current Rating: 200 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Package / Case: 5mm x 20mm (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Mounting Type: Requires Holder (exact match required)

All substitute parts listed below meet these core criteria. Variations in response time (Medium Blow vs. Slow Blow), breaking capacity, melting I²t, DC cold resistance, and approval agencies are noted but do not disqualify substitution when the primary electrical and mechanical parameters align.

Engineering Selection Recommendations

All substitute parts listed above are active products with current manufacturing status, providing supply continuity for the obsolete 5MT 200. Selection should prioritize parts with ROHS3 compliance to meet modern regulatory requirements.

For applications requiring medium-blow response characteristics matching the original 5MT 200, the 20102000001, 20102000021, and BK1/GMC-200-R options are appropriate. The 20102000001 and 20102000021 variants offer higher breaking capacity (80A vs. 35A) and ROHS3 compliance. The BK1/GMC-200-R provides medium-blow response with ROHS3 compliance and CSA, KC, and UL certifications.

For applications where slow-blow response is acceptable, the 0218.200HXP, 0218.200MXP, and GDC-200MA options provide ROHS3-compliant alternatives with broader approval agency coverage. The 0218.200HXP and 0218.200MXP are functionally identical and offer CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE certifications. The GDC-200MA provides cURus and IMQ certifications with slow-blow characteristics.

Frequently Asked Questions (FAQ)

Q: Can I use a slow-blow fuse as a substitute for the medium-blow 5MT 200?

A: Slow-blow and medium-blow fuses have different thermal response characteristics. While both meet the electrical and mechanical parameters (200 mA, 250 V, 5mm x 20mm), the response time difference affects circuit protection behavior. Application-specific requirements determine compatibility.

Q: What is the significance of breaking capacity differences between substitute parts?

A: Breaking capacity indicates the maximum fault current the fuse can safely interrupt. The 5MT 200 and most substitutes are rated at 35A, while 20102000001 and 20102000021 are rated at 80A. Higher breaking capacity provides additional safety margin in high-fault-current applications.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts listed (0218.200HXP, 0218.200MXP, 20102000001, 20102000021, BK1/GMC-200-R, GDC-200MA) are ROHS3 compliant. The original 5MT 200 is RoHS non-compliant.

Q: Do substitute parts require the same holder as the 5MT 200?

A: All substitute parts are 5mm x 20mm cartridge fuses requiring a holder, matching the mechanical package of the 5MT 200. Existing holders are compatible with all listed substitutes.

Q: Which substitute offers the broadest approval agency coverage?

A: The 0218.200HXP and 0218.200MXP offer the most comprehensive certifications: CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE.
