Equivalent & Substitute Parts for 0RLS006.T

Part Overview

The 0RLS006.T is a 6A 600 VAC fast-blow cartridge fuse from Littelfuse Inc.'s POWR-GARD® RLS series. This component is classified as obsolete, requiring identification of active equivalent parts for continued system support and procurement. The cartridge fuse requires a compatible holder for installation and is designed for electrical and industrial applications where fast-response overcurrent protection is required.

Key Parameters

Substitute Part Grouping Explanation

The KLSR006.T qualifies as a direct substitute based on the following alignment of critical parameters:

• Current Rating: Both parts rated at 6A
• AC Voltage Rating: Both rated at 600 VAC
• Fuse Type: Both are cartridge fuses requiring a holder
• Physical Dimensions: Identical at 0.811" Dia x 5.000" L
• Response Time: Both are fast-blow fuses
• Approval Agencies: Both carry CE, CSA, and UL certifications

The KLSR006.T represents an active product with enhanced specifications, including DC voltage capability (250 VDC) and higher breaking capacity (200kA AC, 20kA DC versus 10kA), making it suitable for replacement in applications requiring the 0RLS006.T's core parameters.

Parameter Comparison

Engineering Selection Recommendations

The KLSR006.T is the direct substitute for the obsolete 0RLS006.T. Both parts share identical current ratings, AC voltage specifications, physical dimensions, and approval certifications. The KLSR006.T is an active product with ROHS3 compliance, addressing regulatory requirements that the original part does not meet. The higher breaking capacity and DC voltage rating of the KLSR006.T provide enhanced performance margins without compromising compatibility with existing holder assemblies. Selection of the KLSR006.T eliminates obsolescence risk while maintaining electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the KLSR006.T be used as a direct replacement for the 0RLS006.T in existing systems?

A: Yes. Both parts have identical current ratings (6A), AC voltage ratings (600 VAC), physical dimensions (0.811" Dia x 5.000" L), and response characteristics (fast-blow). The KLSR006.T will function in any holder designed for the 0RLS006.T.

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

A: Class H and Class RK1 are distinct fuse classifications. The KLSR006.T's RK1 classification provides higher breaking capacity (200kA AC) compared to the 0RLS006.T's Class H rating (10kA). Both classes are approved for industrial and electrical applications.

Q: Does the KLSR006.T's DC voltage rating affect AC-only applications?

A: No. The KLSR006.T's 250 VDC rating is an additional capability that does not impact performance in AC circuits. The 600 VAC rating remains the primary specification for AC applications.

Q: Are there any packaging differences between these parts?

A: The 0RLS006.T is listed with standard cartridge packaging, while the KLSR006.T is packaged in a box. Both are cartridge fuses with identical physical dimensions and holder compatibility.

Q: Why is RoHS compliance important for this substitution?

A: The KLSR006.T is ROHS3 compliant, meeting current environmental and regulatory standards. The 0RLS006.T is RoHS non-compliant. For new designs or systems subject to RoHS requirements, the KLSR006.T is the appropriate selection.
