LT600302SR Equivalent & Substitute Parts

Part Overview

The LT600302SR is a fuse block cartridge designed for 600V, 30A applications with 2-circuit configuration and chassis mount orientation. Manufactured by Littelfuse Inc., this component is classified as obsolete, necessitating identification of equivalent alternatives for ongoing system maintenance and new designs. The part accommodates Class T cartridge fuses in a screw terminal configuration suitable for industrial electrical protection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LT600302SR is determined by matching the following critical parameters: voltage rating (600V), current rating (30A), number of circuits (2), fuse type (cartridge), fuse size (0.563" Dia x 1.5" L), fuseholder type (block), and termination style (screw terminal). Mounting type variation is permitted when system integration allows, as the electrical and mechanical interface with Class T fuses remains consistent. Both identified substitutes satisfy these core requirements while differing in mounting configuration and product status.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring direct form-fit-function replacement with identical mounting configuration, the T60030-2SR from Eaton - Bussmann Electrical Division is the primary equivalent. This part maintains chassis mount orientation identical to the LT600302SR while offering active product status and RoHS compliance.

The LFT600302S from Littelfuse Inc. provides an alternative within the same manufacturer family with ROHS3 compliance and active status. Selection of this part requires accommodation of DIN Rail mounting in place of chassis mount, necessitating mechanical redesign of the mounting interface.

Both substitutes are electrically and mechanically compatible with Class T cartridge fuses and maintain identical electrical specifications. Component selection should prioritize active product status and regulatory compliance requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can the LFT600302S replace the LT600302SR in existing designs? A: Electrical compatibility is confirmed. The LFT600302S differs in mounting type (DIN Rail vs. Chassis Mount), requiring mechanical redesign of the mounting structure. All electrical parameters and fuse compatibility remain identical.

Q: What is the significance of the mounting type difference? A: Mounting type determines physical installation method. Chassis mount uses direct screw fastening to equipment enclosures. DIN Rail mounting uses standardized rail attachment. Substitution requires corresponding changes to the mechanical installation interface.

Q: Are all three parts compatible with Class T fuses? A: All three parts are specified for use with Class T fuses in the 0.563" Dia x 1.5" L (14.3mm x 38.1mm) size. Fuse compatibility is consistent across all options.

Q: What is the difference between RoHS non-compliant and RoHS3 Compliant status? A: RoHS compliance indicates adherence to Restriction of Hazardous Substances regulations. The LT600302SR predates current compliance requirements (obsolete status). The LFT600302S and T60030-2SR meet current regulatory standards, making them suitable for applications with RoHS requirements.

Q: Can I use T60030-2SR as a direct replacement for LT600302SR? A: Yes. The T60030-2SR maintains identical mounting type (Chassis Mount), voltage rating (600V), current rating (30A), circuit count (2), fuse type (Cartridge), fuse size, and termination style (Screw Terminal). No mechanical redesign is required.
