Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0213005.MXEP are qualified based on the following critical parameters that must remain constant:

• Current Rating: 5 A
• Voltage Rating (AC): 250 V
• Fuse Type: Cartridge, Glass
• Response Time: Slow Blow
• Package / Case: 5mm x 20mm (Axial)
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C to 125°C
• RoHS Status: ROHS3 Compliant

The identified substitute parts maintain these core electrical and mechanical specifications, ensuring direct functional equivalence in circuit protection applications. Variations in secondary parameters such as Breaking Capacity, Melting I²t, DC Cold Resistance, and approval agency certifications do not preclude substitution when the primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

All three parts—0213005.MXEP, 0218005.MXEP, and 0219005.MXAEP—maintain Active product status and ROHS3 compliance, confirming their suitability for current and future applications. Selection among these equivalents should be based on:

Approval Agency Requirements: The main part 0213005.MXEP carries BSI and UR certifications in addition to CCC, CE, CSA, PSE, SEMKO, and VDE. The substitute 0218005.MXEP includes K-MARK and UL certifications. The substitute 0219005.MXAEP includes UL certification. Applications requiring specific regional or industry certifications should reference the approval agency list for each part number.

Breaking Capacity Considerations: The 0219005.MXAEP offers a higher breaking capacity of 150 A compared to 50 A for both 0213005.MXEP and 0218005.MXEP. This parameter does not affect substitution eligibility but may be relevant for applications with higher fault current requirements.

Melting I²t Variation: The 0218005.MXEP exhibits a lower Melting I²t value (111) compared to the main part (314) and the 0219005.MXAEP (544). This indicates faster thermal response in the 0218005.MXEP. Applications with specific thermal time-constant requirements should account for this difference.

Frequently Asked Questions (FAQ)

Q: Can 0218005.MXEP be used as a direct replacement for 0213005.MXEP?

A: Yes. Both parts share identical current rating (5 A), voltage rating (250 V AC), fuse type (Cartridge, Glass), response time (Slow Blow), package dimensions (5mm x 20mm), and mounting type (Through Hole). The primary difference is the Melting I²t value (111 vs. 314), which affects thermal response speed but does not prevent functional substitution in applications designed for the 0213005.MXEP.

Q: Can 0219005.MXAEP be used as a direct replacement for 0213005.MXEP?

A: Yes. Both parts meet all critical substitution criteria: identical current rating (5 A), voltage rating (250 V AC), fuse type (Cartridge, Glass), response time (Slow Blow), package dimensions (5mm x 20mm), and mounting type (Through Hole). The 0219005.MXAEP provides higher breaking capacity (150 A vs. 50 A) and higher Melting I²t (544 vs. 314), representing enhanced performance characteristics.

Q: What is the significance of the Melting I²t parameter in fuse selection?

A: Melting I²t defines the thermal energy required to melt the fuse element. Lower values indicate faster response to overcurrent conditions, while higher values indicate slower response. For the 0213005.MXEP (314), 0218005.MXEP (111), and 0219005.MXAEP (544), all three maintain Slow Blow response classification, but the 0218005.MXEP responds faster thermally than the main part.

Q: Are there differences in approval certifications among these parts?

A: Yes. The 0213005.MXEP includes BSI and UR certifications. The 0218005.MXEP includes K-MARK and UL certifications. The 0219005.MXAEP includes UL certification. Applications requiring specific regional certifications (such as UL for North America or K-MARK for Korea) should verify that the selected part number carries the required approval.

Q: Do all three parts have the same physical dimensions?

A: Yes. All three parts conform to the 5mm x 20mm (Axial) package specification with dimensions of 0.228" Dia x 0.886" L (5.80mm x 22.50mm), ensuring mechanical compatibility in through-hole mounting applications.

Q: What is the operating temperature range for these fuses?

A: All three parts operate within the range of -55°C to 125°C, providing consistent thermal performance across the specified temperature envelope.
