TPS-60LB Equivalent & Substitute Parts

Part Overview

The TPS-60LB is a 60A 170 VDC fuse cartridge manufactured by Eaton - Bussmann Electrical Division, part of the Telpower® TPS series. This bolt-mount cylindrical fuse is designed for telecom applications requiring DC protection at high current ratings. The part is currently active in production with 880 units in stock. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity for applications where the TPS-60LB specifications are met by alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS-60LB are identified based on strict electrical and mechanical parameter matching:

Critical Matching Parameters:

• Current Rating: 60A (exact match required)
• Voltage Rating (DC): 170 VDC (exact match required)
• Fuse Type: Cartridge (exact match required)
• Mounting Type: Bolt Mount (exact match required)
• Package / Case: Cylindrical, Blade Terminal (Bolt) (exact match required)
• Breaking Capacity @ Rated Voltage: 100kA (exact match required)

The substitute part 0TLS060.TXL from Littelfuse Inc. meets all critical electrical parameters. Physical dimensions vary slightly in length (1.740" vs. 0.874"), which may affect mechanical fit in specific mounting configurations and requires verification against the application's physical constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the TPS-60LB and 0TLS060.TXL are active products with equivalent electrical specifications (60A, 170 VDC, 100kA breaking capacity). Both carry CE certification and RoHS compliance, meeting regulatory requirements for telecom applications.

The primary consideration for substitution is the physical length difference: the 0TLS060.TXL is nearly twice as long (1.740" vs. 0.874"). This dimensional variance may affect mechanical fit within existing fuse holders or mounting assemblies designed for the TPS-60LB. Electrical performance and protection characteristics are equivalent; however, physical installation compatibility must be confirmed for the specific application before substitution.

The 0TLS060.TXL carries cURus certification (combining CE and UL/cUL marks), while the TPS-60LB carries CE and UR certification. Both certifications are valid for telecom applications; the choice depends on the specific regulatory requirements of the end application.

Frequently Asked Questions (FAQ)

Q: Can the 0TLS060.TXL be used as a direct replacement for the TPS-60LB?

A: Electrical substitution is valid based on matching current rating (60A), voltage rating (170 VDC), breaking capacity (100kA), and fuse type (cartridge). However, the 0TLS060.TXL is 0.866" longer, which may prevent physical installation in fuse holders designed for the TPS-60LB. Mechanical fit must be confirmed for the specific application.

Q: Are there differences in response time between these parts?

A: The 0TLS060.TXL is specified as Fast Blow. The TPS-60LB response time is not provided in the available data. If response time is a critical parameter for the application, this difference should be evaluated against circuit protection requirements.

Q: Do both parts meet the same regulatory standards?

A: Both parts carry CE certification and RoHS compliance. The TPS-60LB carries UR approval; the 0TLS060.TXL carries cURus approval. Both certifications are valid for telecom applications. Confirm which certification is required for your specific end-use application.

Q: What is the impact of the dimensional difference on substitution?

A: The diameter remains identical (0.563"), ensuring terminal compatibility. The length difference (0.874" vs. 1.740") affects only the physical space required in the mounting assembly. Verify that the fuse holder or mounting bracket can accommodate the longer cartridge before substitution.

Q: Are both parts currently available?

A: Yes. The TPS-60LB has 880 units in stock; the 0TLS060.TXL has 977 units in stock, both listed as new original inventory.
