Littelfuse 0218005.H Glass Cartridge Fuse 5A 250VAC 5x20mm Equivalent & Substitute Parts

Part Overview

The Littelfuse 0218005.H is a 5 A, 250 V AC/DC glass cartridge fuse with slow-blow response characteristics, designed for 5mm x 20mm holder mounting. This part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain identical electrical and mechanical specifications. Substitute parts must preserve the 5 A current rating, 250 V voltage rating, slow-blow response time, and 5mm x 20mm form factor to ensure direct functional replacement in existing applications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict parametric matching across the following criteria:

Current Rating: 5 A (exact match required)
Voltage Rating: 250 V AC (exact match required)
Response Time: Slow Blow (exact match required)
Package / Case: 5mm x 20mm (exact match required)
Fuse Type: Cartridge, Glass (exact match required)
Breaking Capacity: 50 A (exact match required)
Operating Temperature: -55°C to 125°C (exact match required)

All substitute parts listed below meet these mandatory electrical and mechanical parameters. Variations in melting I²t, DC cold resistance, approval agencies, and RoHS compliance status do not affect functional substitution capability within the specified parameter set.

Engineering Selection Recommendations

All listed substitute parts are classified as Active products, ensuring continued availability and manufacturing support. The primary distinction between substitute options relates to product compliance status and approval agency certifications.

Series 218 substitutes (0218005.HXP, 0218005.MXBP, 0218005.MXF11P, 0218005.MXF14P, 0218005.MXP, 0218005.TXP, 0218005.VXP) maintain the original series designation and are ROHS3 compliant with certifications including CCC, CE, CSA, PSE, SEMKO, UL, and VDE. These parts demonstrate the closest design continuity to the obsolete 0218005.H.

Series 213 substitutes (0213005.MXBP, 0213005.MXP, 0213005.TXP) are ROHS3 compliant with certifications including BSI, CCC, CE, CSA, PSE, SEMKO, UR, and VDE. These parts meet all mandatory electrical and mechanical parameters and represent an alternative series option.

Selection between Series 218 and Series 213 substitutes depends on application-specific certification requirements and existing design documentation. Both series maintain identical electrical performance within the specified parameter set.

Frequently Asked Questions (FAQ)

Q: Can any of these substitute parts directly replace the 0218005.H in existing applications?

A: Yes. All listed substitute parts match the mandatory electrical and mechanical parameters: 5 A current rating, 250 V AC voltage rating, slow-blow response time, 5mm x 20mm package, 50 A breaking capacity, and -55°C to 125°C operating temperature range. Direct substitution is supported within these parameter constraints.

Q: What is the significance of the different suffix designations (HXP, MXBP, MXP, TXP, VXP)?

A: Suffix designations indicate packaging and certification variations within the same electrical specification. All variants maintain identical current rating, voltage rating, response time, and form factor. Selection among variants depends on packaging requirements and specific approval agency certifications needed for the application.

Q: Are Series 213 and Series 218 substitutes interchangeable?

A: Yes, within the specified parameter set. Both series provide 5 A, 250 V AC/DC slow-blow cartridge fuses in 5mm x 20mm form factor with 50 A breaking capacity. Series selection depends on design documentation requirements and certification preferences. Both series are Active products with full manufacturing support.

Q: What is the difference between ROHS3 compliant and RoHS non-compliant variants?

A: The original 0218005.H is RoHS non-compliant. All substitute parts listed are ROHS3 compliant, indicating conformance to current environmental and material restriction standards. This compliance status does not affect electrical or mechanical performance within the specified parameter set.

Q: How do melting I²t and DC cold resistance variations affect substitution?

A: Melting I²t and DC cold resistance are secondary characteristics that do not affect substitution eligibility. All parts meet the mandatory 50 A breaking capacity and slow-blow response time specifications. Variations in these secondary parameters remain within acceptable ranges for direct functional replacement.

Q: What inventory levels are available for substitute parts?

A: Inventory availability varies by part number. 0218005.MXP maintains the highest inventory at 42,700 pieces. Series 213 alternatives (0213005.MXBP, 0213005.MXP, 0213005.TXP) provide 1,727, 3,700, and 1,007 pieces respectively. Specific inventory requirements should be confirmed with the component supplier.
