Littelfuse 0218.160HXP Equivalent & Substitute Parts

Part Overview

The Littelfuse 0218.160HXP is a 160 mA, 250 V AC/DC glass cartridge fuse with 5mm x 20mm dimensions and slow-blow response characteristics. This component is classified as Active product status and is designed for applications requiring overcurrent protection in AC and DC circuits. Equivalent and substitute parts are necessary when the primary part is unavailable, when alternative manufacturers offer improved lead times, or when design requirements permit selection from multiple qualified sources meeting identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the 0218.160HXP is determined by strict equivalence across the following 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 configuration (requires holder). All substitute parts listed meet these core electrical and mechanical requirements. Variations in secondary parameters such as breaking capacity, melting I²t, DC cold resistance, and approval agency certifications do not disqualify a part from substitution provided the primary parameters remain identical. Parts are grouped by manufacturer and series designation to facilitate cross-reference identification.

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and are ROHS3 compliant. Selection among equivalent parts should be based on certification requirements specific to the application. The Littelfuse 0218.160HXP and 0218.160MXP are direct equivalents within the same manufacturer series. The Littelfuse 0219.160MXAP offers higher breaking capacity (150 A versus 35 A) and elevated melting I²t (0.31 versus 0.219), making it suitable for applications requiring enhanced fault current handling. SCHURTER parts (0034.3109, 0034.5609.11, 0034.5705.11) provide alternatives with varying melting I²t characteristics. Bel Fuse 5ST 160-R and Eaton parts (BK/S506-160-R, GDC-160MA) are qualified alternatives with documented approval certifications. OptiFuse TSD-160MA is available with IEC 60127 certification. All parts are mechanically compatible with standard 5mm x 20mm fuse holders.

Frequently Asked Questions (FAQ)

Q: Can I substitute the Littelfuse 0218.160HXP with any of the listed parts?

A: Yes, all listed parts are electrically and mechanically equivalent. They share identical current rating (160 mA), voltage rating (250 V AC), package dimensions (5mm x 20mm), response time (slow blow), and mounting requirements. Substitution is valid from an electrical standpoint.

Q: What is the difference between the 0218.160HXP and 0218.160MXP?

A: Both parts are Littelfuse Series 218 fuses with identical electrical and mechanical specifications. The primary difference is packaging designation (HXP versus MXP). They are direct equivalents.

Q: Why does the 0219.160MXAP have a higher breaking capacity?

A: The 0219.160MXAP belongs to the Littelfuse 219XA series and is designed for applications requiring higher fault current interruption capability (150 A versus 35 A). It maintains the same 160 mA current rating and 250 V voltage rating but offers enhanced performance in high-fault-current environments.

Q: Are there differences in melting I²t values among the substitutes?

A: Yes. Melting I²t values vary across manufacturers and series. The 0218.160HXP has a melting I²t of 0.219, while alternatives range from 0.08 (Bel Fuse 5ST 160-R) to 1.0 (SCHURTER 0034.5705.11). These variations reflect different thermal response characteristics but do not affect basic substitution eligibility for the specified 160 mA, 250 V application.

Q: Which substitute offers the best certification coverage?

A: The Bel Fuse 5ST 160-R carries the broadest approval agency certifications: CCC, CE, CSA, cURus, IMQ, SEMKO, and VDE. The Littelfuse 0218.160HXP and 0219.160MXAP also provide comprehensive certifications including UL approval. Selection should align with specific regulatory requirements for the end application.

Q: Can I use these fuses in both AC and DC circuits?

A: Yes. All listed parts are rated for 250 V AC/DC operation and are suitable for both AC and DC circuit protection applications within the specified voltage and current parameters.

Q: What is the significance of DC cold resistance variations?

A: DC cold resistance values (ranging from 1.27 to 4.4 Ohms among listed parts) reflect internal fuse element design differences. These variations do not affect substitution eligibility but may influence circuit behavior in low-voltage DC applications where fuse resistance contributes measurably to total circuit impedance.
