Littelfuse 0219.160MXAP Glass Cartridge Fuse 160mA 250VAC 5x20mm Equivalent & Substitute Parts

Part Overview

The Littelfuse 0219.160MXAP is an active-status 160mA 250VAC slow-blow glass cartridge fuse in 5x20mm form factor, designed for circuit protection in AC/DC applications. This fuse requires a holder for installation and is RoHS3 compliant with broad international approvals (CCC, CE, CSA, SEMKO, UL, VDE). Equivalent and substitute parts are identified based on matching electrical ratings, mechanical dimensions, response characteristics, and environmental specifications to ensure direct functional interchangeability in protected circuit designs.

Substitute Part Grouping Explanation

Substitution eligibility for the 0219.160MXAP is determined by strict equivalence across the following parameters:

Current Rating: 160 mA (exact match required)
Voltage Rating: 250 V AC (exact match required)
Fuse Type: Cartridge, Glass (exact match required)
Response Time: Slow Blow (exact match required)
Package / Case: 5mm x 20mm (exact match required)
Mounting Type: Requires Holder (exact match required)
Operating Temperature Range: -55°C ~ 125°C (exact match required)

All substitute parts listed below meet these criteria. Variations in Breaking Capacity, Melting I²t, DC Cold Resistance, and approval agency certifications do not preclude substitution when the above parameters are identical. Selection among substitutes may be based on inventory availability, specific certification requirements, or application-specific compliance needs.

Engineering Selection Recommendations

All listed substitute parts are active-status products with RoHS3 compliance. Selection among equivalents should be based on:

Certification Requirements: The 0219.160MXAP carries CCC, CE, CSA, SEMKO, UL, and VDE approvals. Littelfuse 0218.160HXP and 0218.160MXP include K-MARK certification in addition to CCC, CE, CSA, SEMKO, UL, and VDE. SCHURTER 0034.3109 carries CCC, cURus, and VDE certifications. SCHURTER 0034.5609.11 carries cURus and VDE certifications. SCHURTER 0034.5705.11 carries cURus certification. OptiFuse TSD-160MA is certified to IEC 60127. Application-specific regulatory requirements should determine final selection.
Inventory Availability: 0218.160MXP (3300 pcs), 0034.3109 (2533 pcs), and TSD-160MA (2854 pcs) offer higher stock levels compared to 0219.160MXAP (1234 pcs).
Breaking Capacity Variation: The 0219.160MXAP specifies 150A breaking capacity, while all substitute parts specify 35A. This difference does not affect substitution eligibility but should be evaluated against application fault current requirements.

Frequently Asked Questions (FAQ)

Q: Can 0218.160HXP and 0218.160MXP be used interchangeably with 0219.160MXAP?

A: Yes. Both parts match all critical substitution parameters: 160mA current rating, 250V AC voltage rating, slow-blow response, 5x20mm package, and -55°C to 125°C operating range. Both are Littelfuse products with active status and RoHS3 compliance. Differences in Breaking Capacity (35A vs. 150A) and Melting I²t do not preclude substitution when electrical and mechanical specifications are identical.

Q: What is the difference between Littelfuse and SCHURTER fuses in this list?

A: All parts meet identical electrical and mechanical specifications for 160mA 250VAC slow-blow operation in 5x20mm form factor. Differences lie in manufacturer series designation, approval agency certifications, and Melting I²t values. SCHURTER parts (0034.3109, 0034.5609.11, 0034.5705.11) carry different certification profiles; selection depends on application compliance requirements.

Q: Why does the 0219.160MXAP have a higher Breaking Capacity (150A) than substitute parts (35A)?

A: Breaking Capacity represents the maximum fault current the fuse can safely interrupt. The 0219.160MXAP is rated for 150A breaking capacity, while substitute parts are rated for 35A. This specification difference does not affect substitution eligibility when all other parameters match. Application fault current analysis should determine whether the lower breaking capacity of substitute parts is acceptable for the intended circuit.

Q: Are all these fuses RoHS3 compliant?

A: Yes. All parts listed—0219.160MXAP, 0218.160HXP, 0218.160MXP, 0034.3109, 0034.5609.11, 0034.5705.11, and TSD-160MA—are RoHS3 compliant.

Q: Which substitute part has the best availability?

A: 0218.160MXP offers the highest inventory level at 3300 pieces, followed by TSD-160MA at 2854 pieces and 0034.3109 at 2533 pieces.

Q: Do all substitute parts require a holder for installation?

A: Yes. All parts in this list are cartridge fuses that require a holder for installation. The 5x20mm mechanical form factor is standardized across all parts.
