Equivalent & Substitute Parts for Littelfuse 023201.6MXE

Part Overview

The Littelfuse 023201.6MXE is a 1.6 A 250 V AC/DC glass cartridge fuse with a 5mm x 20mm axial form factor and medium blow response time. This part is classified as obsolete, making identification of active equivalent and substitute parts essential for ongoing design support and procurement continuity. Active alternatives maintain the same electrical and mechanical specifications while offering improved compliance status and broader regulatory approvals.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 023201.6MXE is determined by strict equivalence across the following critical parameters:

• Current Rating: 1.6 A (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Package / Case: 5mm x 20mm Axial (exact match required)
• Response Time: Medium Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity: 100 A (exact match required)

Both substitute parts—023201.6MXEP and 023401.6MXEP—meet all critical electrical and mechanical parameters. The primary distinction lies in product status (active vs. obsolete), regulatory compliance certifications, and secondary electrical characteristics (melting I²t and DC cold resistance).

Parameter Comparison

Engineering Selection Recommendations

Both 023201.6MXEP and 023401.6MXEP are direct functional equivalents to the obsolete 023201.6MXE across all critical electrical and mechanical parameters.

023201.6MXEP maintains the same series designation (232) as the original part and is the closest functional match. It carries active product status, ROHS3 compliance, and certifications from CE, KC, and PSE. This part is suitable for applications requiring regulatory compliance in markets covered by these certifications.

023401.6MXEP represents the next-generation alternative from series 234. It maintains all critical electrical and mechanical specifications while offering the broadest regulatory approval scope, including CE, CSA, K-MARK, PSE, and UL certifications. This part is suitable for applications requiring North American (UL/CSA) and international market compliance.

Both substitutes are ROHS3 compliant and REACH unaffected, addressing environmental and regulatory requirements not met by the obsolete original part. Selection between the two should be based on specific regulatory requirements for the target application and market.

Frequently Asked Questions (FAQ)

Q: Can 023201.6MXEP and 023401.6MXEP be used interchangeably with 023201.6MXE?

A: Yes. Both substitute parts meet all critical electrical and mechanical specifications: 1.6 A current rating, 250 V AC voltage rating, medium blow response time, 5mm x 20mm axial package, 100 A breaking capacity, and through-hole mounting. Functional substitution is direct.

Q: What is the difference between 023201.6MXEP and 023401.6MXEP?

A: Both parts are electrically and mechanically equivalent. The primary differences are series designation (232 vs. 234), regulatory certifications (023401.6MXEP includes UL and CSA), and secondary electrical characteristics (melting I²t and DC cold resistance). For applications requiring North American compliance, 023401.6MXEP is preferred.

Q: Why is the original 023201.6MXE obsolete?

A: The original part does not meet current RoHS3 compliance requirements and carries limited regulatory certifications (METI only). Active substitutes address these compliance gaps while maintaining identical electrical and mechanical performance.

Q: Are there any thermal or performance differences between the substitutes?

A: All three parts operate across the same temperature range (-55°C to 125°C). Secondary electrical characteristics (melting I²t and DC cold resistance) vary slightly between parts but do not affect functional equivalence for standard circuit protection applications.

Q: What packaging options are available?

A: The original part packaging is not specified. Both substitute parts are available in bulk packaging, suitable for production and procurement workflows.
