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

Part Overview

The Littelfuse 0219005.MXA is a 5A 250VAC glass cartridge fuse in 5x20mm form factor, classified as a slow-blow fuse cartridge requiring a holder for installation. This part is currently obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility. Substitute parts must match the core electrical parameters: 5A current rating, 250V AC voltage rating, slow-blow response time, and 5x20mm physical dimensions.

Key Parameters

Parameter	Value
Current Rating	5 A
Voltage Rating (AC)	250 V
Fuse Type	Cartridge, Glass
Response Time	Slow Blow
Package / Case	5mm x 20mm
Mounting Type	Requires Holder
Operating Temperature Range	-55°C to 125°C
Size / Dimension	0.205" Dia x 0.787" L (5.20mm x 20.00mm)

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following mandatory parameters:

Current Rating: 5 A (exact match required)
Voltage Rating: 250 V AC (exact match required)
Response Time: Slow Blow (exact match required)
Physical Dimensions: 5mm x 20mm (exact match required)
Fuse Type: Cartridge, Glass (exact match required)
Mounting: Requires Holder (exact match required)

All identified substitute parts meet these core criteria. Variations in breaking capacity, melting I²t, and DC cold resistance do not preclude substitution when the primary electrical and mechanical parameters align. Parts are grouped by product status and RoHS compliance to facilitate selection based on regulatory requirements.

Engineering Selection Recommendations

Primary Recommendation: 0219005.MXAP

The 0219005.MXAP is the direct active equivalent to the obsolete 0219005.MXA. Both parts share identical series designation (219XA), electrical ratings, and mechanical specifications. The 0219005.MXAP maintains the same 150A breaking capacity and 544 melting I²t as the original part. This part is ROHS3 compliant and carries active product status with 1675 units in stock.

Secondary Alternatives: Series 213 and 218 Parts

Parts from the 213 and 218 series (0213005.MXBP, 0213005.MXP, 0213005.TXP, 0218005.HXP, 0218005.MXBP, 0218005.MXF11P, 0218005.MXF14P, 0218005.MXP, 0218005.TXP) are parametric equivalents meeting all core electrical and mechanical requirements. These alternatives feature reduced breaking capacity (50A versus 150A) and lower melting I²t values. All are ROHS3 compliant with active product status. Selection among these alternatives depends on application-specific breaking capacity requirements and regulatory certifications needed for the end application.

Compliance Considerations

The original 0219005.MXA is RoHS non-compliant. All active substitute parts are ROHS3 compliant, meeting current regulatory requirements. Approval agencies vary across substitute options; verify that the selected part carries certifications required by your application (CCC, CE, CSA, PSE, SEMKO, UL, VDE, BSI, UR, K-MARK, KC).

Frequently Asked Questions (FAQ)

Q: Can I use a Series 213 or 218 fuse as a direct replacement for the 0219005.MXA?

A: Yes. Series 213 and 218 parts meet all mandatory substitution criteria: 5A current rating, 250V AC voltage rating, slow-blow response time, and 5x20mm physical dimensions. The primary difference is reduced breaking capacity (50A versus 150A). Confirm that your application does not require the higher breaking capacity of the original part before substitution.

Q: What is the difference between breaking capacity and melting I²t?

A: Breaking capacity is the maximum fault current the fuse can safely interrupt. Melting I²t is a measure of the fuse's thermal energy absorption before melting. The original 0219005.MXA has a breaking capacity of 150A and melting I²t of 544. Series 213 and 218 alternatives have lower values (50A breaking capacity, 111–314 melting I²t). These differences do not affect basic circuit protection function but may impact performance in high-fault-current environments.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts listed are ROHS3 compliant. The original 0219005.MXA is RoHS non-compliant. If your application requires RoHS compliance, select from the active substitute options.

Q: Does packaging type affect substitution?

A: The original 0219005.MXA is packaged as a new original part. All substitute parts are available in bulk packaging. Packaging type does not affect electrical or mechanical compatibility; it reflects inventory and distribution format only.

Q: Which substitute part has the highest inventory availability?

A: The 0218005.MXP has the highest inventory with 42,700 units in stock, followed by 0213005.MXP with 3,700 units. The direct equivalent 0219005.MXAP has 1,675 units available.

Q: Can I mix different substitute parts in the same circuit?

A: All substitute parts meet identical electrical and mechanical specifications for the core parameters (5A, 250V AC, slow-blow, 5x20mm). Mixing parts from different series is acceptable from a functional standpoint, though maintaining consistency within a design is a standard engineering practice.
