Equivalent & Substitute Parts for 0LKS015.S

Part Overview

The 0LKS015.S is a 15A 600VAC cartridge fuse link manufactured by Littelfuse Inc. under the POWR-GARD® LKS series. This component is classified as obsolete, requiring identification of active equivalent parts for continued system support. The fast-blow response characteristic and H-class rating make this fuse suitable for electrical and industrial applications requiring reliable overcurrent protection. Substitute parts must maintain compatibility with existing holder assemblies while meeting or exceeding the original electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Current Rating: Must be 15A
• Voltage Rating (AC): Must be 600 VAC minimum
• Mounting Type: Must require holder (cartridge configuration)
• Response Time: Fast Blow characteristic
• Approval Agencies: Must include CE, CSA, and UL certifications

The identified substitute parts maintain these core electrical parameters while offering improved product status and compliance profiles. Physical dimension variations are acceptable provided the parts remain compatible with standard cartridge fuse holders rated for 600VAC service.

Parameter Comparison

Engineering Selection Recommendations

KLSR015.T is the primary recommended substitute. This part maintains identical current rating, AC voltage rating, and mounting requirements while offering active product status and superior breaking capacity (200kA AC versus 10kA). The ROHS3 compliance and enhanced DC voltage rating (250 VDC) provide additional operational flexibility. Physical length difference (5.000" versus 3.748") requires verification of holder compatibility before deployment.

LKS-15 is an alternative substitute manufactured by Eaton - Bussmann Electrical Division with active product status and RoHS compliance. Limited technical specification data is provided for this part; verification of voltage rating, breaking capacity, and physical dimensions is necessary before selection.

Both substitutes carry CE, CSA, and UL certifications equivalent to the original part.

Frequently Asked Questions (FAQ)

Q: Can KLSR015.T be used as a direct replacement for 0LKS015.S?

A: KLSR015.T maintains the same current rating (15A), AC voltage rating (600 VAC), response time (Fast Blow), and mounting type (Requires Holder). The primary consideration is physical length: KLSR015.T measures 5.000" compared to 3.748" for the original part. Compatibility depends on the specific holder assembly in use. Verify holder specifications before substitution.

Q: What is the difference between fuse classes H and RK1?

A: Both are cartridge fuse classes. Class H is a general-purpose fast-blow fuse. Class RK1 is a current-limiting fuse with higher breaking capacity. KLSR015.T (RK1) provides 200kA breaking capacity at rated voltage compared to 10kA for the original H-class part, offering enhanced protection in high-fault-current environments.

Q: Are the substitute parts RoHS compliant?

A: Yes. KLSR015.T is ROHS3 compliant, and LKS-15 is RoHS compliant. The original 0LKS015.S is RoHS non-compliant.

Q: Do the substitute parts maintain the same approval certifications?

A: KLSR015.T carries CE, CSA, and UL certifications identical to the original part. LKS-15 certification status is not specified in available data.

Q: Can LKS-15 be used interchangeably with 0LKS015.S?

A: LKS-15 has active product status and RoHS compliance. However, critical electrical parameters including voltage rating, breaking capacity, and response time are not specified. Complete technical verification is required before selection.
