Littelfuse 0218.160MXBP Equivalent & Substitute Parts

Part Overview

The Littelfuse 0218.160MXBP is a 160 mA, 250 V AC/DC glass cartridge fuse with 5mm x 20mm dimensions and slow-blow response characteristics. This part is classified as obsolete. Equivalent and substitute parts are available from Littelfuse across multiple series (218, 219XA, 618) and from alternative manufacturers such as SCHURTER, offering active product status with maintained electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution is determined by strict equivalence across the following critical parameters: current rating (160 mA), voltage rating (250 V AC), fuse type (cartridge glass), package dimensions (5mm x 20mm), response time (slow blow), and mounting requirement (requires holder). All substitute parts maintain these core electrical and mechanical specifications.

Littelfuse Series 218 parts (0218.160HXP, 0218.160MX8810P, 0218.160MXP, 0218.160TXP, 0218.160VXP) and Series 219XA parts (0219.160MXABP, 0219.160MXAP, 0219.160TXAP) are direct parametric equivalents with active product status. Series 618 part (0618.160MXP) maintains identical electrical ratings and dimensions. SCHURTER 0034.3109 (FST 5x20 series) provides cross-manufacturer equivalence with matching specifications.

Variations in melting I²t values (0.144, 0.219, 0.31), DC cold resistance (2.55 Ohms, 3.7 Ohms), and breaking capacity (35A, 150A) do not preclude substitution when the primary electrical and mechanical parameters align. These secondary characteristics reflect design variations within the same functional category.

Engineering Selection Recommendations

For applications requiring direct replacement of the obsolete 0218.160MXBP, the following active alternatives are available:

Littelfuse Series 218 (35A Breaking Capacity): Parts 0218.160HXP, 0218.160MX8810P, 0218.160MXP, 0218.160TXP, and 0218.160VXP maintain the same electrical ratings and breaking capacity as the original. All carry active product status and ROHS3 compliance. Parts 0218.160TXP and 0218.160VXP match the original melting I²t value of 0.144.

Littelfuse Series 219XA (150A Breaking Capacity): Parts 0219.160MXABP, 0219.160MXAP, and 0219.160TXAP provide enhanced breaking capacity (150A) while maintaining identical current, voltage, and package specifications. These are suitable for applications requiring higher fault current withstand capability.

Littelfuse Series 618: Part 0618.160MXP offers equivalent electrical and mechanical specifications with active product status.

Cross-Manufacturer Alternative: SCHURTER 0034.3109 (FST 5x20 series) provides parametric equivalence from an alternative manufacturer with active product status and ROHS3 compliance.

All substitute parts are certified to CCC, CE, CSA, SEMKO, UL, and VDE standards. Selection should be based on application requirements for breaking capacity, melting I²t characteristics, and DC cold resistance specifications.

Frequently Asked Questions (FAQ)

Q: Can I substitute 0218.160MXBP with any of the listed alternatives?

A: Yes. All listed parts maintain the critical electrical parameters (160 mA, 250 V AC) and mechanical specifications (5mm x 20mm cartridge glass, slow-blow response, requires holder). Physical and electrical compatibility is assured across all substitutes.

Q: What is the difference between Series 218 and Series 219XA parts?

A: The primary difference is breaking capacity. Series 218 parts have 35A breaking capacity, while Series 219XA parts have 150A breaking capacity. Both maintain identical current ratings, voltage ratings, and package dimensions. Series 219XA is suitable for applications with higher fault current requirements.

Q: Why do melting I²t values differ among substitutes?

A: Melting I²t represents the thermal energy required to melt the fuse element and is a design characteristic. Variations (0.144, 0.219, 0.31) reflect different internal element designs within the same current and voltage rating. Selection should match application thermal requirements.

Q: Is the SCHURTER 0034.3109 a direct replacement?

A: Yes. The SCHURTER 0034.3109 maintains all critical electrical and mechanical parameters. It is a cross-manufacturer equivalent suitable for applications where supplier diversification is required.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, meeting environmental and material restriction requirements.

Q: What certifications apply to these fuses?

A: All parts carry CCC, CE, CSA, SEMKO, UL, and VDE certifications. Series 219XA and 618 parts include additional certifications (K-MARK, UR) depending on the specific part number.
