Key Parameters

Substitute Part Grouping Explanation

Substitution of the Littelfuse 023201.6MXP is determined by strict equivalence across the following parameters: current rating (1.6 A), voltage rating (250 V AC), fuse type (cartridge glass), physical package dimensions (5mm x 20mm), response time classification (medium blow), breaking capacity (100 A), and operating temperature range (-55°C to 125°C). All substitute parts listed maintain these electrical and mechanical specifications. Differences in melting I²t values, DC cold resistance, and approval certifications are noted but do not preclude substitution when the core parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

All three parts—023201.6MXP, 023401.6MXP, and MSC-1.6A—are active products with full RoHS3 compliance and meet the core electrical and mechanical requirements for 1.6 A, 250 V AC/DC glass cartridge fuse applications in 5mm x 20mm form factor.

The Littelfuse 023401.6MXP provides expanded approval coverage including CSA, K-MARK, and UL certifications in addition to CE and PSE, making it suitable for applications requiring broader regulatory compliance.

The OptiFuse MSC-1.6A carries cULus and UL 248 certifications, positioning it for applications with specific North American and international UL requirements.

Selection should be based on the specific approval certifications required by the application and regional regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the 023401.6MXP be used as a direct replacement for the 023201.6MXP?

A: Yes. Both parts share identical electrical ratings (1.6 A, 250 V AC), fuse type (cartridge glass), physical dimensions (5mm x 20mm), response time (medium blow), and breaking capacity (100 A). Both are active products with RoHS3 compliance.

Q: What is the difference in melting I²t values between these parts?

A: The melting I²t values differ slightly: 023201.6MXP (6.96), 023401.6MXP (6.14), and MSC-1.6A (7.795). These variations reflect different thermal characteristics but do not affect substitution eligibility when core electrical parameters remain constant.

Q: Are there approval certification differences between the substitute parts?

A: Yes. The 023201.6MXP carries CE, KC, and PSE approvals. The 023401.6MXP includes CE, CSA, K-MARK, PSE, and UL. The MSC-1.6A carries cULus and UL 248. Selection should align with application-specific certification requirements.

Q: Do all parts require a fuse holder?

A: Yes. All three parts are cartridge-type fuses requiring a compatible 5mm x 20mm fuse holder for installation.

Q: Can these parts be used interchangeably in the same circuit?

A: Yes, provided the application does not mandate specific approval certifications. All parts meet identical electrical and mechanical specifications for 1.6 A, 250 V AC/DC protection.
