Equivalent & Substitute Parts for Littelfuse 0216004.MXE

Part Overview

The Littelfuse 0216004.MXE is a 4 A, 250 V AC/DC ceramic cartridge fuse with fast-blow response characteristics, designed for 5mm x 20mm through-hole mounting applications. This part is classified as obsolete, making identification of active equivalent and substitute components essential for ongoing system support and new design implementations. Substitute parts must maintain identical electrical ratings and mechanical form factors to ensure direct compatibility in existing circuit designs.

Substitute Part Grouping Explanation

Substitution eligibility for the 0216004.MXE is determined by strict equivalence across the following parameters:

Current Rating: 4 A (exact match required)
Voltage Rating (AC): 250 V (exact match required)
Fuse Type: Cartridge, Ceramic (exact match required)
Response Time: Fast Blow (exact match required)
Package / Case: 5mm x 20mm (Axial) (exact match required)
Mounting Type: Through Hole (exact match required)
Breaking Capacity @ Rated Voltage: 1.5 kA (exact match required)
Operating Temperature Range: -55°C to 125°C (exact match required)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the original component.

Engineering Selection Recommendations

0216004.MXEP (Littelfuse Inc.) is the primary substitute for the obsolete 0216004.MXE. Both components are from the same manufacturer and series (216). The 0216004.MXEP maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance. This part carries expanded regulatory approvals including VDE certification and demonstrates superior inventory availability.

0001.1010.PT (SCHURTER Inc.) serves as an alternative cross-manufacturer substitute. This component meets all electrical and mechanical equivalence criteria and holds active product status with ROHS3 compliance. The cURus approval agency certification differs from the Littelfuse options, reflecting SCHURTER's regulatory pathway. Physical dimensions show minor variation (0.213" diameter versus 0.228"), remaining within the 5mm x 20mm form factor specification.

For new designs and ongoing production, 0216004.MXEP is the recommended primary selection due to manufacturer continuity and expanded certification coverage. The 0001.1010.PT provides a viable alternative when supply constraints or specific regulatory requirements necessitate cross-manufacturer sourcing.

Frequently Asked Questions (FAQ)

Q: Can 0216004.MXEP directly replace 0216004.MXE in existing applications?

A: Yes. Both components share identical current rating (4 A), voltage rating (250 V AC), fuse type (ceramic cartridge), response time (fast blow), package dimensions (5mm x 20mm), and breaking capacity (1.5 kA). Direct substitution is electrically and mechanically compatible.

Q: What is the primary difference between 0216004.MXE and 0216004.MXEP?

A: The 0216004.MXE is classified as obsolete, while 0216004.MXEP maintains active product status. The 0216004.MXEP also provides ROHS3 compliance and expanded regulatory certifications (VDE, KC). Electrical and mechanical parameters remain equivalent.

Q: Can SCHURTER 0001.1010.PT be used as a substitute?

A: Yes. The 0001.1010.PT meets all electrical equivalence requirements (4 A, 250 V AC, fast-blow ceramic cartridge, 1.5 kA breaking capacity) and maintains the 5mm x 20mm through-hole form factor. Physical diameter shows minor variation (5.40mm versus 5.80mm) but remains within specification tolerance.

Q: Are there compliance differences between the substitute parts?

A: Yes. The 0216004.MXEP carries CCC, CE, CSA, KC, PSE, SEMKO, UL, and VDE approvals with ROHS3 compliance. The 0001.1010.PT holds cURus certification with ROHS3 compliance. Selection should align with target market regulatory requirements.

Q: What is the melting I²t specification, and does it affect substitution?

A: Melting I²t values are 14.996 (0216004.MXE), 14.995 (0216004.MXEP), and 12.6 (0001.1010.PT). These minor variations reflect manufacturing tolerances within the same fast-blow ceramic fuse category and do not preclude substitution for equivalent circuit protection applications.

Q: Is packaging type a consideration for substitution?

A: The 0216004.MXE is supplied in standard packaging, while 0216004.MXEP and 0001.1010.PT are supplied in bulk packaging. This distinction affects procurement and handling but does not impact electrical or mechanical compatibility.
