Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GMC-10-R is determined by strict parametric alignment across the following critical criteria:

Primary Substitution Criteria:

• Current Rating: 10 A (exact match required)
• Voltage Rating (AC): 125 V (exact match required)
• Package / Case: 5mm x 20mm (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Medium Blow (exact match required)
• Mounting Type: Requires Holder (exact match required)

All substitute parts listed maintain identical values across these parameters. Secondary parameters including breaking capacity, melting I²t, DC cold resistance, and approval agencies may vary within acceptable engineering tolerances for the application category. Substitute parts are grouped by manufacturer and series designation while maintaining full parametric equivalence in the primary criteria.

Parameter Comparison

Engineering Selection Recommendations

Eaton GMC Series (Direct Manufacturer Equivalents): BK/GMC-10-R and BK1/GMC-10-R are direct equivalents manufactured by Eaton - Electronics Division. These parts maintain identical electrical and mechanical specifications to the GMC-10-R, including breaking capacity, melting I²t, and DC cold resistance. Both parts carry MITI and UL approvals (BK1/GMC-10-R carries UR certification). Selection between these variants is based on inventory availability and specific approval requirements for the target application.

Littelfuse 233 Series (0233010.MXBP, 0233010.MXP): These Littelfuse parts maintain full parametric equivalence across primary substitution criteria. The 233 series offers enhanced breaking capacity (10kA versus 200A) and broader approval coverage including CE, CSA, and PSE certifications in addition to UL. The 0233010.MXP variant provides significantly higher inventory availability (46,300 pieces) compared to other substitutes. Operating temperature range extends to -55°C ~ 125°C.

Littelfuse 232 Series (0232010.MX125P): The 0232010.MX125P maintains parametric equivalence with a breaking capacity of 300A and carries CE, KC, and PSE approvals. This variant offers the lowest DC cold resistance (0.0059 Ohms) among all substitutes. Operating temperature range is -55°C ~ 125°C.

Selection Basis: All listed substitutes are ROHS3 compliant and maintain active product status. Selection should be based on application-specific approval requirements, breaking capacity specifications, and inventory availability. Littelfuse variants provide broader international certification coverage and extended operating temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can BK/GMC-10-R be used as a direct replacement for GMC-10-R? A: Yes. BK/GMC-10-R is manufactured by Eaton - Electronics Division and maintains identical electrical and mechanical specifications, including current rating, voltage rating, package dimensions, response time, breaking capacity, and melting I²t. Both parts carry MITI and UL approvals.

Q: What is the difference between BK/GMC-10-R and BK1/GMC-10-R? A: Both parts are manufactured by Eaton - Electronics Division and maintain identical electrical and mechanical specifications. The primary difference is the approval agency designation: BK/GMC-10-R carries MITI and UL approvals, while BK1/GMC-10-R carries MITI and UR approvals. Selection depends on application-specific certification requirements.

Q: Are Littelfuse 233 series fuses (0233010.MXBP, 0233010.MXP) compatible with GMC-10-R applications? A: Yes. Both Littelfuse 233 series parts maintain identical primary parameters: 10 A current rating, 125 V AC voltage rating, 5mm x 20mm package, medium-blow response time, and cartridge glass fuse type. The 233 series offers higher breaking capacity (10kA) and broader international certifications (CE, CSA, PSE, UL). Operating temperature range extends to -55°C ~ 125°C.

Q: What is the difference between 0233010.MXBP and 0233010.MXP? A: Both parts are Littelfuse 233 series fuses with identical electrical and mechanical specifications. The primary difference is inventory availability: 0233010.MXP has significantly higher stock (46,300 pieces) compared to 0233010.MXBP (2,006 pieces). Electrical performance and certifications are equivalent.

Q: Can 0232010.MX125P be used instead of GMC-10-R? A: Yes. The 0232010.MX125P maintains identical primary parameters: 10 A current rating, 125 V AC voltage rating, 5mm x 20mm package, medium-blow response time, and cartridge glass fuse type. This Littelfuse 232 series variant offers a breaking capacity of 300A and carries CE, KC, and PSE approvals. Operating temperature range is -55°C ~ 125°C.

Q: What does "requires holder" mean for these fuse types? A: All listed fuses are cartridge-type fuses that require installation in a dedicated fuse holder. The 5mm x 20mm package dimension specifies the physical size of the fuse cartridge and the corresponding holder cavity. These fuses are not panel-mount or clip-mount designs.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts, including GMC-10-R, BK/GMC-10-R, BK1/GMC-10-R, 0233010.MXBP, 0233010.MXP, and 0232010.MX125P, maintain ROHS3 compliance status.

Q: Which substitute offers the best availability? A: The 0233010.MXP (Littelfuse 233 series) offers the highest inventory availability with 46,300 pieces in stock, compared to 2,004 pieces for BK/GMC-10-R and lower quantities for other variants.
