Littelfuse 0219002.MXAE Glass Cartridge Fuse 2A 250VAC 5x20mm Equivalent & Substitute Parts

Part Overview

The Littelfuse 0219002.MXAE is a 2A 250VAC glass cartridge fuse with slow-blow response characteristics, designed for through-hole mounting in 5mm x 20mm form factor applications. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The 219XA series fuse provides protection in AC/DC circuits with a breaking capacity of 150A at rated voltage and operates across a temperature range of -55°C to 125°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 0219002.MXAE is determined by strict equivalence across 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 / 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)

Substitute parts are grouped into two categories:

Direct Manufacturer Equivalent: Parts from the same manufacturer (Littelfuse) with identical electrical and mechanical specifications but different product status or packaging.

Parametric Equivalent: Parts meeting all critical electrical and mechanical parameters but potentially differing in breaking capacity, melting I²t, or DC cold resistance. These parts maintain functional compatibility within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

0219002.MXAEP (Direct Manufacturer Equivalent): This part is the primary substitute for the obsolete 0219002.MXAE. It maintains identical electrical specifications, breaking capacity, melting I²t, and DC cold resistance. The part is in active production status with ROHS3 compliance, making it suitable for new designs and ongoing production support. Packaging differs (bulk versus original), but electrical and mechanical performance are equivalent.

0213002.MXEP (Parametric Equivalent): This part meets all critical electrical and mechanical parameters with identical current rating, voltage rating, response time, and package dimensions. Breaking capacity is reduced to 35A, and melting I²t remains at 92.705. This part is in active production with ROHS3 compliance and higher inventory availability. Selection is appropriate where the reduced breaking capacity does not conflict with circuit protection requirements.

0218002.MXEP (Parametric Equivalent): This part meets all critical electrical and mechanical parameters with identical current rating, voltage rating, response time, and package dimensions. Breaking capacity is reduced to 35A, and melting I²t is significantly lower at 14.45. DC cold resistance differs at 0.0293 Ohms. This part is in active production with ROHS3 compliance. Selection requires verification that the lower melting I²t and reduced breaking capacity align with circuit protection specifications.

All substitute parts carry equivalent approval agency certifications (CCC, CE, CSA, PSE, SEMKO, UL, VDE) and maintain the same operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can 0219002.MXAEP directly replace 0219002.MXAE in existing designs?

A: Yes. The 0219002.MXAEP is a direct equivalent with identical electrical specifications, breaking capacity, and melting I²t. The only difference is product status (active versus obsolete) and packaging format (bulk). No circuit modifications are required.

Q: What is the difference between the direct equivalent and parametric equivalents?

A: The direct equivalent (0219002.MXAEP) maintains all electrical characteristics of the original part. Parametric equivalents (0213002.MXEP and 0218002.MXEP) meet the core protection requirements (2A, 250V, slow-blow, 5x20mm) but differ in breaking capacity and melting I²t. Selection depends on whether these differences affect circuit protection performance.

Q: Why do 0213002.MXEP and 0218002.MXEP have lower breaking capacity?

A: Breaking capacity is a design characteristic of the fuse element and housing. These parts are from different series (213 and 218 versus 219XA) and have different mechanical designs. The 35A breaking capacity is still suitable for many applications, but must be verified against circuit requirements.

Q: Are all substitute parts RoHS compliant?

A: The original 0219002.MXAE is RoHS non-compliant. All substitute parts (0219002.MXAEP, 0213002.MXEP, and 0218002.MXEP) are ROHS3 compliant, making them suitable for designs requiring environmental compliance.

Q: Can I use 0218002.MXEP if the melting I²t is lower?

A: The melting I²t of 14.45 for 0218002.MXEP is significantly lower than the original 92.705. This affects the fuse's response to overcurrent conditions. Selection requires verification that the lower melting I²t does not compromise circuit protection or cause nuisance trips under normal operating conditions.

Q: What is the inventory status of these parts?

A: 0219002.MXAE (obsolete): 767 pcs. 0219002.MXAEP (active): 739 pcs. 0213002.MXEP (active): 15,486 pcs. 0218002.MXEP (active): 2,300 pcs. Inventory levels reflect current availability and should be verified with the supplier for procurement planning.

Q: Do all parts have the same approval certifications?

A: All parts carry CCC, CE, CSA, PSE, SEMKO, and VDE certifications. 0213002.MXEP adds BSI and UR certifications. 0218002.MXEP adds K-MARK certification. These certifications support use in regulated applications across multiple markets.
