Key Parameters

Substitute Part Grouping Explanation

Substitution of the GMC-200-R is determined by the following critical parameters:

Primary Matching Criteria:

• Current Rating: 200 mA (exact match required)
• Voltage Rating: 250 V AC (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)

Secondary Compatibility Factors:

• Response Time: Medium Blow or Slow Blow (application-dependent)
• Breaking Capacity: 35A or higher (higher values acceptable)
• Approval Certifications: CSA, UL, KC-MARK (compliance verification)
• RoHS Status: ROHS3 Compliant (regulatory requirement)

Parts are grouped into three categories based on substitution relationship:

Direct Manufacturer Equivalents: Parts from Eaton with identical specifications and response time characteristics.

Parametric Equivalents: Parts from alternative manufacturers matching all critical electrical and mechanical parameters with medium blow response time.

Similar Parts: Parts with matching core parameters but different response time (slow blow) or enhanced breaking capacity, suitable for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Eaton Variants): BK/GMC-200-R and BK1/GMC-200-R are direct equivalents to GMC-200-R with identical electrical and mechanical specifications. Both parts maintain medium blow response time and 35A breaking capacity. Selection between these variants depends on packaging designation and internal inventory management. All three Eaton parts hold active product status and comply with CSA, UL, and KC-MARK certifications.

Parametric Equivalent (Medium Blow Response): 20102000021P (Littelfuse Inc.) and MSC-200MA (OptiFuse) match the GMC-200-R in current rating, voltage, package dimensions, and medium blow response time. Both parts are RoHS3 compliant and active in production. The 20102000021P features 80A breaking capacity and cULus certification. The MSC-200MA provides 100A breaking capacity with cULus and UL 248 certifications. These parts are suitable for direct substitution where Eaton variants are unavailable.

Alternative Parts (Slow Blow Response): 0218.200MXP and 0218.200HXP (Littelfuse Inc., Series 218) match core electrical and mechanical parameters but operate with slow blow response time instead of medium blow. These parts feature higher melting I²t values (0.341 versus 0.032) and extended operating temperature range (-55°C to 125°C). Selection of slow blow variants requires application verification to confirm compatibility with circuit protection requirements. Both parts hold comprehensive certifications including CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE.

Frequently Asked Questions (FAQ)

Q: Can BK/GMC-200-R and BK1/GMC-200-R be used interchangeably with GMC-200-R?

A: Yes. Both parts are manufactured by Eaton - Electronics Division and maintain identical electrical ratings (200 mA, 250 V AC), response time (medium blow), package dimensions (5mm x 20mm), and breaking capacity (35A). All three parts comply with CSA, UL, and KC-MARK certifications and RoHS3 requirements.

Q: What is the difference between medium blow and slow blow response times?

A: Response time determines the fuse's reaction speed to overcurrent conditions. Medium blow fuses (GMC-200-R, 20102000021P, MSC-200MA) activate at standard overcurrent levels. Slow blow fuses (0218.200MXP, 0218.200HXP) tolerate temporary current surges and activate only at sustained overcurrent conditions. Selection depends on circuit characteristics and protection requirements.

Q: Are Littelfuse and OptiFuse parts direct replacements for Eaton GMC-200-R?

A: Littelfuse 20102000021P and OptiFuse MSC-200MA are parametric equivalents matching all critical specifications: 200 mA current rating, 250 V voltage rating, 5mm x 20mm package, medium blow response, and RoHS3 compliance. Both parts are active in production and hold appropriate certifications. Littelfuse 0218.200MXP and 0218.200HXP are functionally compatible but feature slow blow response time and require application verification.

Q: What breaking capacity should be selected?

A: The GMC-200-R specifies 35A breaking capacity at rated voltage. Substitute parts with equal or higher breaking capacity (20102000021P at 80A, MSC-200MA at 100A) are acceptable and provide enhanced fault current handling. Breaking capacity selection depends on circuit fault current levels and system protection requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (BK/GMC-200-R, BK1/GMC-200-R, 0218.200MXP, 0218.200HXP, 20102000021P, MSC-200MA) are RoHS3 compliant and suitable for applications requiring regulatory compliance.

Q: What certifications should be verified for critical applications?

A: The GMC-200-R holds CSA, KC-MARK, and UL certifications. Direct Eaton equivalents (BK/GMC-200-R, BK1/GMC-200-R) maintain these certifications. Littelfuse parametric equivalents hold cULus certification. Littelfuse slow blow variants (0218.200MXP, 0218.200HXP) provide comprehensive certifications including CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE. Certification selection depends on regional regulatory requirements and application standards.
