Key Parameters

Substitute Part Grouping Explanation

The 023401.6MXEP manufactured by Littelfuse Inc. qualifies as a direct substitute based on the following critical parameters:

• Current Rating: Identical at 1.6 A
• Voltage Rating (AC): Identical at 250 V
• Fuse Type: Identical cartridge glass construction
• Response Time: Identical medium blow characteristic
• Breaking Capacity: Identical at 100 A
• Mounting Type: Identical through-hole configuration
• Operating Temperature Range: Identical -55°C ~ 125°C
• RoHS3 Compliance: Both parts meet RoHS3 requirements
• REACH Status: Both parts are REACH unaffected

Physical dimensions show minor variation within acceptable tolerances for through-hole mounting applications.

Parameter Comparison

Engineering Selection Recommendations

The 023401.6MXEP is a direct functional equivalent for the obsolete 5MTP 1.6-R. Both components share identical electrical specifications across all critical parameters: current rating, voltage rating, response time, and breaking capacity.

The Littelfuse 023401.6MXEP carries active product status with broader regulatory approvals including UL and K-MARK certifications, in addition to the CE, CSA, and PSE certifications shared with the original part. Both components maintain ROHS3 compliance and REACH unaffected status.

Physical dimensions show minor variation (approximately 0.3mm diameter and 0.65mm length increase), which remains within acceptable tolerances for standard through-hole fuse holder applications. DC cold resistance differs slightly (0.0884 Ohms versus 0.076 Ohms), representing a 16% increase that remains negligible for fuse circuit protection applications.

Frequently Asked Questions (FAQ)

Q: Can the 023401.6MXEP replace the 5MTP 1.6-R in existing designs?

A: Yes. Both components meet identical electrical specifications for current rating, voltage rating, response time, and breaking capacity. Physical dimensions are compatible with standard 5mm x 20mm through-hole fuse holders.

Q: What is the significance of the product status difference?

A: The 5MTP 1.6-R is obsolete, while the 023401.6MXEP is active. Active status ensures ongoing availability, manufacturing support, and compliance with current regulatory standards.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. The 023401.6MXEP carries additional UL and K-MARK certifications beyond the shared CE, CSA, and PSE approvals.

Q: Does the difference in DC cold resistance affect circuit performance?

A: The 16% difference in DC cold resistance (0.076 Ohms versus 0.0884 Ohms) is negligible for fuse protection applications and does not impact functional equivalence.

Q: Are physical dimension differences a concern?

A: Minor dimensional variations (0.3mm diameter, 0.65mm length) remain within standard tolerances for through-hole fuse holder compatibility and do not affect mechanical fit or electrical performance.
