Littelfuse 0318002.MXP Glass Cartridge Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0318002.MXP is a 2 A, 250 V AC/DC fast-blow glass cartridge fuse in 3AB/3AG package format (1/4" x 1-1/4" axial). This through-hole fuse is designed for circuit protection in industrial and commercial applications. The part maintains active product status with full compliance to CE, CSA, KC, PSE, and UL approval agencies. Equivalent and substitute parts are identified when identical electrical and mechanical parameters are maintained across the same fuse category, enabling seamless component replacement in existing designs and procurement scenarios.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Littelfuse 0318002.MXP are classified based on strict electrical and mechanical parameter alignment within the glass cartridge fuse category:

Parametric Equivalent (0318002.HXP): Identical across all critical parameters including 2 A current rating, 250 V AC voltage rating, fast-blow response, 3AB/3AG package, 100 A breaking capacity, and -55°C ~ 125°C operating temperature. Manufactured by Littelfuse Inc. under the same 318 series. This part provides direct functional equivalence with no design or application modifications required.

Manufacturer Recommended Substitute (BK/AGC-V-2-R): Eaton Electronics Division part matching the same 2 A, 250 V AC/DC electrical specifications, fast-blow response, 3AB/3AG package format, and -55°C ~ 125°C operating temperature. Approved by CSA and UL. Dimensional tolerance (0.266" Dia x 1.292" L versus 0.275" Dia x 1.288" L) and melting I²t characteristics (17.52 versus 5.2) remain within acceptable mechanical and thermal performance boundaries for this fuse category.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (0318002.MXP): Recommended for new designs and applications requiring full compliance with CE, KC, and PSE certifications in addition to CSA and UL. Maintains exact dimensional and thermal characteristics specified in original circuit protection designs.

Direct Replacement (0318002.HXP): Suitable for field replacement and procurement continuity. Identical electrical and mechanical specifications with equivalent Littelfuse manufacturing quality assurance. Maintains all original approval certifications.

Cross-Manufacturer Alternative (BK/AGC-V-2-R): Eaton Electronics Division part approved for applications where CSA and UL compliance satisfies regulatory requirements. Acceptable for designs where CE, KC, and PSE certifications are not mandated. Dimensional variation (0.009" diameter reduction, 0.004" length increase) and elevated melting I²t (17.52 versus 5.2) remain within mechanical tolerance for standard 3AB/3AG fuse holders. Selection requires confirmation that circuit protection characteristics align with application thermal and fault-current profiles.

Frequently Asked Questions (FAQ)

Q: Can 0318002.HXP be used as a direct replacement for 0318002.MXP? A: Yes. Both parts are manufactured by Littelfuse Inc. with identical electrical ratings (2 A, 250 V AC), response time (fast-blow), package format (3AB/3AG), and operating temperature range (-55°C ~ 125°C). No circuit modifications are required.

Q: What are the key differences between the Littelfuse and Eaton substitute parts? A: The BK/AGC-V-2-R (Eaton) differs in approval certifications (CSA, UL only versus CE, CSA, KC, PSE, UL), dimensional tolerance (0.266" Dia x 1.292" L versus 0.275" Dia x 1.288" L), and melting I²t characteristic (17.52 versus 5.2). All three parts maintain identical 2 A, 250 V AC fast-blow specifications and 100 A breaking capacity.

Q: Is the BK/AGC-V-2-R suitable for applications requiring CE or PSE certification? A: The BK/AGC-V-2-R carries CSA and UL approval only. Applications mandating CE, KC, or PSE compliance require the Littelfuse 0318002.MXP or 0318002.HXP.

Q: Will dimensional differences affect fuse holder compatibility? A: The BK/AGC-V-2-R dimensions (0.266" Dia x 1.292" L) fall within standard 3AB/3AG fuse holder mechanical tolerance. Physical fit in existing holders is maintained. Verify holder specifications if dimensional precision is critical to application design.

Q: How do melting I²t values affect part selection? A: Melting I²t (5.2 for Littelfuse, 17.52 for Eaton) defines thermal energy required to melt the fuse element. Both values are valid for 2 A fast-blow cartridge fuses. Selection depends on circuit fault-current profile and thermal protection requirements. Consult application circuit analysis to confirm compatibility.

Q: Are all three parts RoHS compliant? A: Yes. The 0318002.MXP and 0318002.HXP are ROHS3 Compliant. The BK/AGC-V-2-R is RoHS Compliant. Both compliance levels meet current environmental regulations for electronic component manufacturing.
