GMC-150-R Equivalent & Substitute Parts Reference

Part Overview

The GMC-150-R is a glass cartridge fuse manufactured by Eaton - Electronics Division, rated for 150 mA at 250 V AC/DC. This component is designed for circuit protection in applications requiring a medium-blow response characteristic. The fuse operates in a 5mm x 20mm form factor and requires a compatible holder for installation.

The GMC-150-R maintains Active product status with full regulatory compliance. Substitute parts are identified based on identical electrical ratings, mechanical dimensions, and approval certifications to ensure direct functional equivalence in circuit protection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GMC-150-R are identified through strict parameter matching across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

Electrical Parameters:

• Current Rating: 150 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Response Time: Medium Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 35A (exact match required)
• Melting I²t: 0.022 (exact match required)
• DC Cold Resistance: 2.555 Ohms (exact match required)

Mechanical Parameters:

• Package / Case: 5mm x 20mm (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Mounting Type: Requires Holder (exact match required)

Compliance Parameters:

• Approval Agencies: CSA, KC-MARK, UL (all certifications must be present)
• RoHS Status: ROHS3 Compliant (exact match required)

Only parts meeting all these criteria are classified as direct substitutes. The GMC-150-R series designation indicates product family consistency within Eaton's component line.

Parameter Comparison

Engineering Selection Recommendations

Both the GMC-150-R and BK/GMC-150-R are Active status products manufactured by Eaton - Electronics Division with identical electrical specifications and mechanical form factors. Selection between these parts is based on availability and supply chain requirements rather than technical differentiation.

Compliance Basis: Both parts carry CSA, KC-MARK, and UL approvals, confirming suitability for regulated applications. ROHS3 compliance status is identical across both parts, meeting environmental and material restriction requirements.

Inventory Consideration: The BK/GMC-150-R variant currently maintains higher inventory availability (1359 Pcs) compared to the GMC-150-R (683 Pcs), which may influence procurement decisions for high-volume applications.

Application Compatibility: Both parts function identically in 5mm x 20mm fuse holder installations. No circuit redesign, holder modification, or application re-qualification is required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can BK/GMC-150-R replace GMC-150-R in existing designs?

A: Yes. Both parts are electrically and mechanically identical with matching current ratings (150 mA), voltage ratings (250 V AC), response characteristics (Medium Blow), and physical dimensions (5mm x 20mm). No design changes are required.

Q: Are the approval certifications identical?

A: Yes. Both parts carry CSA, KC-MARK, and UL approvals. ROHS3 compliance status is identical, confirming equivalent regulatory standing.

Q: What is the difference between GMC-150-R and BK/GMC-150-R?

A: The parts are functionally equivalent. The "BK/" prefix designation indicates a variant within Eaton's product line. All electrical parameters, mechanical specifications, and certifications are identical.

Q: Do these fuses require a specific holder type?

A: Yes. Both GMC-150-R and BK/GMC-150-R require a compatible 5mm x 20mm fuse holder for installation. The fuse cartridge cannot be used without a holder.

Q: What is the melting I²t value, and why is it important?

A: The melting I²t value is 0.022 for both parts. This parameter defines the thermal energy required to melt the fuse element and is critical for coordinating circuit protection with upstream overcurrent devices.

Q: Are there any temperature or environmental restrictions?

A: Operating temperature specifications are not provided in the technical parameters. Moisture Sensitivity Level (MSL) is Not Applicable for both parts, indicating no moisture-related handling restrictions during storage or installation.

Q: What is the DC Cold Resistance specification?

A: Both parts have a DC Cold Resistance of 2.555 Ohms. This specification defines the resistance of the fuse element at room temperature and is used in circuit analysis for voltage drop calculations.
