Littelfuse 2205.500MXP Glass Cartridge Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 2205.500MXP is an active-status 500 mA, 250 V AC/DC slow-blow glass cartridge fuse in 2AG package format (5mm x 15mm axial). This through-hole component is designed for circuit protection applications requiring moderate current ratings with slow-blow response characteristics. Finding equivalent substitute parts may be necessary due to inventory availability, supply chain considerations, or procurement requirements while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2205.500MXP is determined by strict equivalence across the following critical parameters:

• Current Rating: 500 mA (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 / Case: 2AG, 5mm x 15mm (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity: 35 A @ Rated Voltage (exact match required)
• Melting I²t: 1.16 (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• DC Cold Resistance: 0.6935 Ohms (exact match required)
• Approval Agencies: CE, CSA, UL (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The substitute part 2205.500HXP meets all these criteria and is therefore a direct parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the 2205.500MXP and 2205.500HXP are active-status products manufactured by Littelfuse Inc. with identical electrical and mechanical specifications.

Selection between these two part numbers may be based on inventory availability or procurement lead time, as they are direct parametric equivalents suitable for identical circuit protection applications.

Frequently Asked Questions (FAQ)

Q: Can the 2205.500HXP be used as a direct replacement for the 2205.500MXP?

A: Yes. The 2205.500HXP is a direct parametric equivalent with identical current rating (500 mA), voltage rating (250 V AC), fuse type (cartridge, glass), response time (slow blow), package format (2AG, 5mm x 15mm axial), breaking capacity (35 A), melting I²t (1.16), operating temperature range (-55°C ~ 125°C), DC cold resistance (0.6935 Ohms), and regulatory approvals (CE, CSA, UL).

Q: Are there any mechanical compatibility differences between these parts?

A: No. Both parts use identical 2AG package format with 5mm x 15mm axial dimensions and through-hole mounting, ensuring mechanical compatibility in existing PCB layouts and fuse holders.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the 2205.500MXP and 2205.500HXP carry identical approvals (CE, CSA, UL) and maintain ROHS3 compliance status.

Q: What is the significance of the melting I²t value of 1.16?

A: The melting I²t value defines the thermal energy required to melt the fuse element. An identical value of 1.16 ensures both parts respond identically to overcurrent conditions, maintaining consistent circuit protection characteristics.

Q: Can these fuses be used in both AC and DC applications?

A: Yes. Both parts are rated for 250 V AC/DC operation, allowing use in either AC or DC circuits within the specified voltage and current parameters.
