L15S005.T Equivalent & Substitute Parts

Part Overview

The L15S005.T is a 5A 150VAC/150VDC fast-blow cartridge fuse manufactured by Littelfuse under the POWR-GARD® L15S series. This component is designed for semiconductor applications and requires a compatible fuse holder for installation. The part maintains active product status with 803 units in current inventory. Substitute parts are identified when equivalent electrical ratings, mechanical dimensions, and approval certifications align with the original specification, enabling direct replacement in applications where the primary part is unavailable or supply constraints exist.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L15S005.T is determined by strict equivalence across the following parameters:

• Current Rating: 5A (exact match required)
• Voltage Rating: 150 VAC and 150 VDC (both must match)
• Fuse Type: Cartridge (mechanical and electrical compatibility)
• Package / Case: 5AG, 10mm x 38mm (Midget) (physical interchangeability)
• Size / Dimension: 0.406" Dia x 1.500" L (10.30mm x 38.10mm) (holder compatibility)
• Breaking Capacity: 100kA AC, 20kA DC (fault protection equivalence)
• Mounting Type: Requires Holder (installation method consistency)

The FWA-5A10F meets all substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the L15S005.T and FWA-5A10F are active products with equivalent electrical and mechanical specifications. Selection between these parts should be based on:

• Approval Agency Requirements: The L15S005.T carries CSA certification in addition to CE and UR. If CSA approval is mandated by application or regional standards, the L15S005.T is the required choice. The FWA-5A10F holds CE and UR certifications.
• RoHS Compliance: Both parts meet RoHS requirements. The L15S005.T is ROHS3 compliant; the FWA-5A10F is RoHS compliant.
• Supply Availability: Current inventory shows 803 units of L15S005.T and 708 units of FWA-5A10F available.
• Packaging: L15S005.T is supplied in Box packaging; FWA-5A10F is supplied in Bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can the FWA-5A10F directly replace the L15S005.T in all applications?

A: Direct replacement is possible when CSA certification is not a system requirement. Both parts share identical electrical ratings (5A, 150VAC/150VDC), fuse type (cartridge), package designation (5AG), and physical dimensions (10mm x 38mm). Verify that your application or regional standards do not mandate CSA approval before substitution.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the L15S005.T and FWA-5A10F are 0.406" diameter by 1.500" length (10.30mm x 38.10mm) and use the 5AG package designation. They are mechanically interchangeable in any standard 5AG fuse holder.

Q: What is the difference in breaking capacity between these parts?

A: There is no difference. Both parts have a breaking capacity of 100kA AC and 20kA DC at rated voltage, ensuring equivalent fault protection performance.

Q: Does packaging type affect electrical performance?

A: No. The L15S005.T (Box packaging) and FWA-5A10F (Bulk packaging) are electrically and mechanically identical. Packaging type reflects only the distribution format and does not influence component function or compatibility.

Q: Are both parts RoHS compliant?

A: Yes. The L15S005.T is ROHS3 compliant, and the FWA-5A10F is RoHS compliant. Both meet RoHS requirements for hazardous substance restrictions.
