Littelfuse 0219001.M Glass Cartridge Fuse 1A 250VAC 5x20mm Equivalent & Substitute Parts

Part Overview

The Littelfuse 0219001.M is a 1 A, 250 V AC/DC glass cartridge fuse in 5mm x 20mm form factor, designed for circuits requiring slow-blow response characteristics. This part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility. Substitute parts must match the core electrical parameters: 1 A current rating, 250 V AC voltage rating, slow-blow response, and 5x20mm package dimensions.

Substitute Part Grouping Explanation

Substitute parts for the 0219001.M are selected based on strict electrical and mechanical parameter matching:

Primary Matching Criteria:

Current Rating: 1 A (exact match required)
Voltage Rating: 250 V AC (exact match required)
Fuse Type: Cartridge, Glass (exact match required)
Response Time: Slow Blow (exact match required)
Package Dimensions: 5mm x 20mm (exact match required)
Mounting Type: Requires Holder (exact match required)
Operating Temperature: -55°C to 125°C (exact match required)

All identified substitute parts meet these criteria. Differences in breaking capacity, melting I²t, DC cold resistance, and approval agencies do not preclude substitution when the primary electrical and mechanical parameters align. Active product status is preferred for long-term availability.

Engineering Selection Recommendations

Primary Recommendation: 0219001.MXABP

The 0219001.MXABP is the direct functional equivalent to the obsolete 0219001.M. Both parts share the same series designation (219XA vs. 219), identical electrical ratings (1 A, 250 V AC), and matching breaking capacity (150 A). The 0219001.MXABP is active, ROHS3 compliant, and carries equivalent international certifications (CCC, CE, CSA, PSE, SEMKO, UL, VDE). This part provides the highest compatibility with existing circuit designs.

Secondary Alternatives: Series 218 Parts (0218001.HXP, 0218001.MXBP, 0218001.MXF5P, 0218001.MXP, 0218001.TXP, 0218001.VXP)

Series 218 parts maintain all core electrical parameters but feature reduced breaking capacity (35 A vs. 150 A) and lower melting I²t values (6.73 vs. 3.33 for the original). These parts are suitable for applications where the lower breaking capacity is acceptable. All are active, ROHS3 compliant, and widely available.

Tertiary Alternatives: Series 213 Parts (0213001.MXBP, 0213001.MXP, 0213001.TXP)

Series 213 parts also maintain core electrical parameters with breaking capacity of 35 A and higher melting I²t (19.2). These are active and ROHS3 compliant alternatives when Series 218 availability is limited.

Compliance Consideration:

The original 0219001.M is RoHS non-compliant. All substitute parts listed are ROHS3 compliant, meeting current regulatory requirements for new designs and procurement.

Frequently Asked Questions (FAQ)

Q: Can I use a Series 218 fuse as a direct replacement for the 0219001.M?

A: Series 218 parts (0218001.HXP, 0218001.MXP, etc.) are electrically compatible as they maintain the 1 A, 250 V AC ratings and slow-blow response. However, they have reduced breaking capacity (35 A vs. 150 A). Use Series 218 only if your circuit design does not require the higher breaking capacity of the original part.

Q: What is the difference between the 0219001.M and 0219001.MXABP?

A: Both parts are from the 219 series with identical electrical ratings and breaking capacity (150 A). The primary difference is product status: 0219001.M is obsolete while 0219001.MXABP is active. The MXABP variant also offers ROHS3 compliance and improved long-term availability.

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

A: All substitute parts listed use bulk packaging and require a fuse holder for installation, matching the original 0219001.M mounting requirements. The 5mm x 20mm form factor is consistent across all alternatives.

Q: Which substitute part has the best availability?

A: The 0218001.MXP (Series 218) has the highest inventory at 17,900 pieces. The 0213001.MXP (Series 213) has 10,400 pieces. Both are active products with strong stock levels.

Q: Do all substitute parts meet the same international certifications as the original?

A: The original 0219001.M carries certifications from BSI, CCC, CSA, KTL, PSE, SEMKO, UR, and VDE. Substitute parts carry overlapping certifications with slight variations. The 0219001.MXABP maintains the most similar certification profile. All listed substitutes meet CCC, CE, CSA, PSE, SEMKO, and VDE standards.

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

A: All listed substitutes are electrically equivalent for the core parameters (1 A, 250 V AC, slow-blow, 5x20mm). However, for consistency and traceability, use a single part number throughout a design or system.
