Littelfuse 0219005.MXE Glass Cartridge Fuse 5A 250VAC 5x20mm Equivalent & Substitute Parts

Part Overview

The Littelfuse 0219005.MXE is a 5A 250VAC glass cartridge fuse with slow-blow response characteristics, designed for through-hole mounting in 5mm x 20mm form factor. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The fuse provides circuit protection with a breaking capacity of 150A at rated voltage and operates across a temperature range of -55°C to 125°C.

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
Breaking Capacity @ Rated Voltage	150 A

Substitute Part Grouping Explanation

Substitute parts for the 0219005.MXE are qualified based on the following mandatory parameters:

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

All three substitute parts meet these core electrical and mechanical parameters. Variations in breaking capacity, melting I²t, DC cold resistance, and regulatory certifications are secondary considerations that do not disqualify substitution but may influence selection based on application-specific requirements.

Engineering Selection Recommendations

All three substitute parts are active products from Littelfuse Inc. and maintain electrical and mechanical compatibility with the obsolete 0219005.MXE.

0219005.MXAEP is the preferred direct substitute. It shares the same series lineage (219XA variant of 219), maintains identical breaking capacity (150A), and carries active product status with ROHS3 compliance. This part provides the closest functional equivalence to the original specification.

0218005.MXEP is an active alternative with ROHS3 compliance and the broadest regulatory certification coverage (CCC, CE, CSA, K-MARK, PSE, SEMKO, UL, VDE). Breaking capacity is reduced to 50A, and melting I²t is 111, closely matching the original part's thermal characteristics. This option is suitable for applications where the lower breaking capacity is acceptable.

0213005.MXEP is an active alternative with ROHS3 compliance. Breaking capacity is 50A with elevated melting I²t of 314. This part is suitable for applications where higher thermal tolerance is required within the 50A breaking capacity constraint.

All substitute parts are available in bulk packaging and carry current inventory levels exceeding 1000 units.

Frequently Asked Questions (FAQ)

Q: Can 0219005.MXAEP directly replace 0219005.MXE in existing designs?

A: Yes. The 0219005.MXAEP maintains identical electrical ratings (5A, 250VAC), fuse type (cartridge glass), response time (slow blow), package dimensions (5mm x 20mm), and breaking capacity (150A). Physical and electrical compatibility is confirmed.

Q: What is the difference between the 50A and 150A breaking capacity options?

A: Breaking capacity defines the maximum fault current the fuse can safely interrupt without rupturing the fuse body. The original 0219005.MXE and substitute 0219005.MXAEP both provide 150A breaking capacity. Substitutes 0218005.MXEP and 0213005.MXEP provide 50A breaking capacity. Selection depends on the maximum prospective fault current in the application circuit.

Q: Are all substitute parts RoHS compliant?

A: The original 0219005.MXE is RoHS non-compliant. All three substitute parts (0213005.MXEP, 0218005.MXEP, 0219005.MXAEP) are ROHS3 compliant, meeting current environmental regulations.

Q: What is the significance of melting I²t values?

A: Melting I²t is a thermal characteristic indicating the energy required to melt the fuse element. The original part specifies 114. Substitute 0218005.MXEP matches this closely at 111. Substitute 0213005.MXEP specifies 314 (higher thermal tolerance), and 0219005.MXAEP specifies 544 (highest thermal tolerance). Selection should align with circuit thermal requirements.

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

A: The original 0219005.MXE is packaged as tape and reel (-). All substitute parts are available in bulk packaging. Confirm packaging requirements with procurement before final selection.

Q: Which regulatory certifications are most critical for my application?

A: Certification requirements depend on end-use application and target markets. The original part carries BSI, CCC, CSA, KTL, PSE, SEMKO, UR, and VDE approvals. Substitute 0219005.MXAEP carries CCC, CE, CSA, PSE, SEMKO, UL, and VDE. Substitute 0218005.MXEP carries the broadest coverage: CCC, CE, CSA, K-MARK, PSE, SEMKO, UL, and VDE. Verify required certifications against your application standards.
