• Current Rating: 2 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Package / Case: 5mm x 20mm (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Medium Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 100A (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Mounting Type: Requires Holder (exact match required)

All substitute parts listed meet these core electrical and mechanical specifications, ensuring functional equivalence in circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance. Selection among equivalent parts should be based on:

• Availability and inventory levels
• Certification requirements specific to the application (CE, CSA, K-MARK, PSE, UL, cULus)
• DC cold resistance specifications if application-critical
• Melting I²t characteristics if thermal response precision is required

The Littelfuse 232 series parts (0232002.MXF34P, 0232002.MXP) and 234 series parts (0234002.MXP, 0234002.MXBP) are all Littelfuse products with comprehensive certification coverage. The OptiFuse MSC-2A provides an alternative from a different manufacturer with UL 248 and cULus certifications.

Frequently Asked Questions (FAQ)

Q: Can 0232002.MXP be used as a direct replacement for 0232002.MXF34P? A: Yes. Both parts share identical electrical ratings (2A, 250VAC), mechanical dimensions (5x20mm), response time (Medium Blow), and breaking capacity (100A). Both are Littelfuse Series 232 products with active status and ROHS3 compliance.

Q: What is the difference between Littelfuse Series 232 and Series 234 fuses? A: Series 232 and 234 parts meet the same electrical and mechanical specifications for this 2A 250VAC application. Differences exist in melting I²t values and DC cold resistance, which may affect thermal response characteristics in specific circuit designs.

Q: Is MSC-2A from OptiFuse compatible with Littelfuse part numbers? A: Yes. The MSC-2A meets all core electrical and mechanical requirements: 2A current rating, 250VAC voltage rating, 5x20mm package, Medium Blow response, and 100A breaking capacity. It is certified to UL 248 and cULus standards.

Q: What certifications should I verify for my application? A: Littelfuse 232 series parts carry CE, KC, and PSE approvals. Littelfuse 234 series parts carry CE, CSA, K-MARK, PSE, and UL approvals. OptiFuse MSC-2A carries cULus and UL 248 certifications. Select based on your regional and application-specific compliance requirements.

Q: Are all substitute parts available in the same packaging? A: Yes. All listed parts are supplied in bulk packaging and use the identical 5mm x 20mm cartridge form factor, requiring the same holder for installation.
