Littelfuse 0219002.MXAEP Glass Cartridge Fuse Equivalent & Substitute Parts

Part Overview

The Littelfuse 0219002.MXAEP is a 2A 250VAC slow-blow glass cartridge fuse in 5mm x 20mm (axial) through-hole package. This component is active in production and widely used in AC/DC circuit protection applications. Equivalent and substitute parts are identified based on matching electrical ratings, mechanical dimensions, response characteristics, and regulatory approvals to ensure direct functional replacement in circuit designs.

Substitute Part Grouping Explanation

Substitution eligibility for the 0219002.MXAEP is determined by the following critical parameters:

Current Rating: 2 A (exact match required)
Voltage Rating: 250 V AC (exact match required)
Response Time: Slow Blow (exact match required)
Package Dimensions: 5mm x 20mm axial (exact match required)
Mounting Type: Through Hole (exact match required)
Operating Temperature: -55°C ~ 125°C (minimum range requirement)
RoHS Compliance: ROHS3 Compliant (regulatory requirement)

All identified substitute parts meet these core electrical and mechanical criteria. Variations in breaking capacity, melting I²t, DC cold resistance, and specific approval agencies do not preclude substitution when the above parameters align.

Engineering Selection Recommendations

All substitute parts listed are active production components with ROHS3 compliance and regulatory approvals suitable for 2A 250VAC slow-blow cartridge fuse applications.

Littelfuse 0213002.MXEP: Parametric equivalent with identical melting I²t (92.705) and DC cold resistance (0.0452 Ohms) to the main part. Includes BSI and UR approvals in addition to standard certifications. Highest inventory availability (15,486 pcs).

Littelfuse 0218002.MXEP: Parametric equivalent with lower melting I²t (14.45) and reduced DC cold resistance (0.0293 Ohms). Includes K-MARK approval. Moderate inventory (2,300 pcs).

Bel Fuse Inc. 5ETP 2-R: Manufacturer-recommended equivalent with 150A breaking capacity matching the main part. Melting I²t (92) and DC cold resistance (0.043 Ohms) are closely aligned. Includes cULus certification. Inventory: 1,706 pcs.

Selection should prioritize application requirements for breaking capacity, thermal response characteristics, and required regulatory certifications.

Frequently Asked Questions (FAQ)

Q: Can 0213002.MXEP directly replace 0219002.MXAEP?

A: Yes. Both parts share identical current rating (2A), voltage rating (250V AC), response time (slow blow), package dimensions (5mm x 20mm), and operating temperature range (-55°C ~ 125°C). Melting I²t and DC cold resistance are identical, ensuring equivalent thermal and electrical performance.

Q: What is the difference between 0218002.MXEP and 0219002.MXAEP?

A: Both are 2A 250VAC slow-blow cartridge fuses in 5mm x 20mm packages. The 0218002.MXEP has lower melting I²t (14.45 vs. 92.705) and reduced DC cold resistance (0.0293 vs. 0.0452 Ohms), resulting in faster thermal response. Breaking capacity is also lower (35A vs. 150A). Selection depends on circuit protection requirements.

Q: Is the Bel Fuse 5ETP 2-R compatible with Littelfuse designs?

A: Yes. The 5ETP 2-R meets all core electrical and mechanical specifications: 2A current rating, 250V AC voltage rating, slow-blow response, and 5mm x 20mm package. Breaking capacity (150A) matches the main part. Cross-manufacturer substitution is valid when these parameters align.

Q: Does package dimension variation affect substitution?

A: The stated dimensions (5.80mm x 22.50mm for Littelfuse parts; 5.50mm x 21.00mm for Bel Fuse 5ETP 2-R) represent physical measurements within the 5mm x 20mm axial cartridge standard. Both fit standard through-hole fuse holders designed for this package class.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status and are suitable for applications requiring environmental compliance.
