Littelfuse 02200007MXW Glass Cartridge Fuse 3A 350VAC 2AG Equivalent & Substitute Parts

Part Overview

The Littelfuse 02200007MXW is a 3 A, 350 V AC/DC glass cartridge fuse in 2AG package format (5mm x 15mm) with slow-blow response characteristics. This component is classified as obsolete product status. Identification of equivalent and substitute parts is necessary due to obsolescence, ensuring continued availability for maintenance, repair, and new design implementations where this fuse specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 02200007MXW are qualified based on the following critical parameters that must remain constant:

• Current Rating: 3 A (exact match required)
• Voltage Rating (AC): 350 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Package / Case: 2AG, 5mm x 15mm (exact match required)
• Response Time: Slow Blow (exact match required)
• Melting I²t: 4.62 (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

Variations permitted in substitute parts include mounting type (Through Hole vs. Requires Holder), breaking capacity at rated voltage, DC cold resistance tolerance, RoHS compliance status, and approval agency certifications. These variations do not affect functional equivalence for the specified electrical and thermal operating conditions.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts 02200007MXP and 02200019MXP maintain electrical and thermal equivalence to the obsolete 02200007MXW across all critical operating parameters. Selection between these substitutes depends on application-specific requirements:

02200007MXP is suitable for applications requiring through-hole mounting configuration with 60A breaking capacity and active product status with full regulatory certifications (CE, CSA, PSE, UL) and ROHS3 compliance.

02200019MXP is suitable for applications requiring holder-based mounting configuration matching the original design with 100A breaking capacity and active product status with full regulatory certifications (CE, CSA, PSE, UL) and ROHS3 compliance.

Both substitute parts provide improved compliance posture compared to the obsolete main part, with ROHS3 compliance and comprehensive approval agency certifications.

Frequently Asked Questions (FAQ)

Q: Can 02200007MXP and 02200019MXP be used interchangeably with 02200007MXW?

A: Both parts are electrically and thermally equivalent. Interchangeability depends on mounting configuration. 02200007MXP requires through-hole mounting, while 02200007MXW and 02200019MXP require holder-based mounting. Verify your circuit board or holder design before selection.

Q: What is the difference between the two substitute parts?

A: The primary difference is mounting type: 02200007MXP uses through-hole mounting (60A breaking capacity), while 02200019MXP uses holder-based mounting (100A breaking capacity). Both maintain identical electrical ratings and response characteristics.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both 02200007MXP and 02200019MXP are ROHS3 compliant, whereas the original 02200007MXW is RoHS non-compliant.

Q: Do the substitute parts have regulatory certifications?

A: Yes. Both substitute parts carry CE, CSA, PSE, and UL certifications, providing broader regulatory acceptance than the original part.

Q: Is there a difference in DC cold resistance between the main part and substitutes?

A: The main part specifies 0.032 Ohms, while both substitutes specify 0.0317 Ohms. This difference is within normal manufacturing tolerance and does not affect functional performance.

Q: What is the 2AG package format?

A: 2AG is a standardized glass cartridge fuse package measuring 5mm diameter by 15mm length (0.177" Dia x 0.571" L). This format is compatible across all three parts listed.
