Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the GMC-1.5-R is based on strict equivalence of the following parameters:

Critical Matching Parameters:

• Current Rating: 1.5 A
• Voltage Rating (AC): 250 V
• Fuse Type: Cartridge, Glass
• Package / Case: 5mm x 20mm
• Response Time: Medium Blow
• Mounting Type: Requires Holder

Secondary Consideration Parameters:

• Breaking Capacity @ Rated Voltage: Substitute parts must maintain or exceed the rated breaking capacity to ensure equivalent fault protection
• Melting I²t: Substitute parts should maintain similar thermal response characteristics
• Approval Agencies: Substitute parts must carry relevant safety certifications (UL, CSA, or equivalent)
• RoHS Compliance: All substitute parts must maintain ROHS3 compliance status

The identified substitute parts (BK/GMC-1.5-R, BK1/GMC-1.5-R, and MSC-1.5A) meet all critical matching parameters. Variations in breaking capacity and melting I²t are noted but do not prevent substitution when the application does not require the specific higher breaking capacity of the main part.

Parameter Comparison

Engineering Selection Recommendations

BK/GMC-1.5-R (Eaton - Electronics Division)

This substitute maintains identical electrical and mechanical specifications to the GMC-1.5-R, including breaking capacity of 100 A and melting I²t of 5.4. The part carries the same approval agencies (CSA, KC-MARK, MITI, UL) and ROHS3 compliance. The primary difference is packaging format (Bulk versus standard). This part is suitable for direct replacement in all applications where GMC-1.5-R is specified.

BK1/GMC-1.5-R (Eaton - Electronics Division)

This substitute matches all critical parameters with one exception: breaking capacity is rated at 35 A compared to 100 A for the main part. The melting I²t remains at 5.4, and all safety certifications are maintained (CSA, KC, MITI, UL). This part is suitable for applications where the lower breaking capacity is acceptable and does not compromise circuit protection requirements.

MSC-1.5A (OptiFuse)

This substitute meets all critical electrical and mechanical parameters. Breaking capacity is 100 A, matching the main part. Melting I²t is 6.713, which differs from the main part's 5.4. The part carries cULus and UL 248 certifications and includes an operating temperature range of -55°C to 125°C. This part is suitable for applications requiring extended temperature operation and is functionally equivalent for standard circuit protection applications.

Frequently Asked Questions (FAQ)

Q: Can BK1/GMC-1.5-R be used as a direct replacement for GMC-1.5-R?

A: BK1/GMC-1.5-R is functionally equivalent for current rating, voltage, fuse type, package size, and response time. However, the breaking capacity is 35 A versus 100 A. This substitute is acceptable only if the application does not require the higher breaking capacity of the main part. Verify circuit fault current levels before substitution.

Q: What is the difference between GMC-1.5-R and BK/GMC-1.5-R?

A: Both parts are manufactured by Eaton - Electronics Division and share identical electrical specifications, breaking capacity (100 A), melting I²t (5.4), and safety certifications. The primary difference is packaging format. BK/GMC-1.5-R is supplied in Bulk packaging, while GMC-1.5-R uses standard packaging. Electrical performance and compatibility are equivalent.

Q: Is MSC-1.5A compatible with GMC-1.5-R in all applications?

A: MSC-1.5A meets all critical substitution parameters: 1.5 A current rating, 250 V AC voltage rating, glass cartridge type, 5mm x 20mm package, and medium-blow response. The melting I²t differs (6.713 versus 5.4), which affects thermal response timing. MSC-1.5A is suitable for standard circuit protection applications and offers extended operating temperature range (-55°C to 125°C).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. GMC-1.5-R, BK/GMC-1.5-R, BK1/GMC-1.5-R, and MSC-1.5A are all ROHS3 compliant, meeting environmental regulatory requirements.

Q: What certifications do the substitute parts carry?

A: BK/GMC-1.5-R and GMC-1.5-R carry CSA, KC-MARK, MITI, and UL certifications. BK1/GMC-1.5-R carries CSA, KC, MITI, and UL certifications. MSC-1.5A carries cULus and UL 248 certifications. All parts meet recognized safety standards for glass cartridge fuses.

Q: Can these fuses be used in DC applications?

A: All parts are rated for 250 V AC/DC operation. The voltage rating applies to both AC and DC circuits. Verify that the application circuit voltage does not exceed 250 V DC.

Q: What is the significance of melting I²t values?

A: Melting I²t indicates the thermal energy required to melt the fuse element. GMC-1.5-R and substitute parts BK/GMC-1.5-R and BK1/GMC-1.5-R have melting I²t of 5.4. MSC-1.5A has melting I²t of 6.713, indicating slightly slower thermal response. Both values are acceptable for medium-blow fuse classification.

Q: Do these fuses require a holder for installation?

A: Yes. All parts (GMC-1.5-R, BK/GMC-1.5-R, BK1/GMC-1.5-R, and MSC-1.5A) require a fuse holder for installation. The 5mm x 20mm cartridge format is designed for use with compatible fuse holders.
