Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GMC-5-R are classified based on strict electrical and mechanical parameter alignment. All identified substitutes maintain identical specifications across the following critical parameters:

• Current Rating: 5 A
• Voltage Rating (AC): 125 V
• Fuse Type: Cartridge, Glass
• Response Time: Medium Blow
• Package / Case: 5mm x 20mm
• Breaking Capacity @ Rated Voltage: 10 kA
• Mounting Type: Requires Holder
• RoHS Status: ROHS3 Compliant

Substitutes are grouped into two categories: Direct Manufacturer Equivalents (same manufacturer, Eaton) and Parametric Equivalents (alternative manufacturers with matching electrical and mechanical specifications).

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and ROHS3 compliance. Selection among GMC-5-R, BK/GMC-5-R, and BK1/GMC-5-R should be based on Eaton product line continuity and approval agency requirements. Both BK/GMC-5-R and BK1/GMC-5-R are direct Eaton equivalents with identical electrical and mechanical specifications.

The 0233005.MXP (Littelfuse 233 series) is a parametric equivalent that meets all core electrical and mechanical requirements. This part carries expanded approval certifications including CE and PSE, and specifies an operating temperature range of -55°C to 125°C. The Littelfuse part exhibits a higher melting I²t value (89.975 versus 58) and slightly elevated DC cold resistance (0.0217 Ohms versus 0.014 Ohms), which remain within acceptable tolerance for this fuse category.

Selection of the Littelfuse 0233005.MXP is appropriate when expanded temperature operating range or additional regulatory certifications are required. Selection of Eaton parts (GMC-5-R, BK/GMC-5-R, BK1/GMC-5-R) is appropriate for applications requiring manufacturer consistency or when specific Eaton approval certifications are mandated.

Frequently Asked Questions (FAQ)

Q: Can BK/GMC-5-R be used as a direct replacement for GMC-5-R?

A: Yes. BK/GMC-5-R is a direct Eaton equivalent with identical electrical specifications (5 A, 125 V AC), fuse type (cartridge, glass), response time (medium blow), package dimensions (5mm x 20mm), breaking capacity (10 kA), and RoHS compliance. Both parts require the same holder and are mechanically and electrically interchangeable.

Q: What is the difference between BK1/GMC-5-R and BK/GMC-5-R?

A: BK1/GMC-5-R and BK/GMC-5-R are both Eaton equivalents with identical electrical and mechanical parameters. The primary difference is in approval agency certifications: BK1/GMC-5-R carries CSA, KC, MITI, and UL approvals, while BK/GMC-5-R carries CSA, KC-MARK, MITI, and UL approvals. Both parts are functionally equivalent for applications requiring these certifications.

Q: Can the Littelfuse 0233005.MXP replace the GMC-5-R?

A: Yes, as a parametric equivalent. The 0233005.MXP maintains identical current rating (5 A), voltage rating (125 V AC), fuse type (cartridge, glass), response time (medium blow), package dimensions (5mm x 20mm), and breaking capacity (10 kA). The part is ROHS3 compliant and carries expanded certifications (CE, CSA, KC, PSE, UL). The Littelfuse part has a higher melting I²t (89.975 versus 58) and slightly higher DC cold resistance (0.0217 Ohms versus 0.014 Ohms), which are within acceptable tolerance for this fuse category.

Q: Does the operating temperature specification of 0233005.MXP affect compatibility?

A: The 0233005.MXP specifies an operating temperature range of -55°C to 125°C. The GMC-5-R does not specify an operating temperature range in the provided data. If the application operates within the -55°C to 125°C range, the Littelfuse part is compatible. If the application requires operation outside this range, the GMC-5-R specification must be clarified with the manufacturer.

Q: Are all substitute parts available in the same packaging?

A: Yes. All substitute parts (BK/GMC-5-R, BK1/GMC-5-R, and 0233005.MXP) are supplied in bulk packaging and maintain the identical 5mm x 20mm cartridge form factor. All parts require a fuse holder for installation.

Q: What approval certifications should I consider for my application?

A: The GMC-5-R carries CSA, KC-MARK, MITI, and UL approvals. BK/GMC-5-R carries the same certifications. BK1/GMC-5-R carries CSA, KC, MITI, and UL approvals. The Littelfuse 0233005.MXP carries CE, CSA, KC, PSE, and UL approvals. Select the part whose certification set matches your application and regional requirements.
