TPS-35LB Equivalent & Substitute Parts Reference

Part Overview

The TPS-35LB is a 35A 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 170 volts with a 35-ampere current rating. The component is active in production with 798 units currently in stock. Equivalent and substitute parts are identified when identical electrical specifications and mechanical compatibility are maintained across alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS-35LB is determined by strict equivalence across the following critical parameters:

• Current Rating: 35A (exact match required)
• Voltage Rating: 170 VDC (exact match required)
• Mounting Type: Bolt Mount (exact match required)
• Package / Case: Cylindrical, Blade Terminal (Bolt) (exact match required)
• Breaking Capacity: 100kA (exact match required)
• Fuse Type: Cartridge (exact match required)

The substitute part 0TLS035.TXL from Littelfuse Inc. meets all critical electrical and mechanical parameters. Both parts maintain identical current, voltage, mounting, and breaking capacity specifications. Physical dimensions vary slightly in length (0.874" vs 1.740"), which reflects design differences between manufacturers but does not affect functional compatibility in bolt-mount applications where the cartridge seats within the holder.

Parameter Comparison

Engineering Selection Recommendations

Both the TPS-35LB and 0TLS035.TXL are active production components with equivalent electrical ratings and mechanical compatibility for bolt-mount cartridge fuse applications at 35A 170 VDC. Selection between these parts may be based on:

• Availability: TPS-35LB has 798 units in stock; 0TLS035.TXL has 1023 units in stock
• Regulatory compliance: Both carry CE certification; TPS-35LB carries UR approval while 0TLS035.TXL carries cURus approval
• Environmental compliance: Both are RoHS compliant (TPS-35LB: RoHS Compliant; 0TLS035.TXL: ROHS3 Compliant)
• Response characteristic: 0TLS035.TXL is specified as Fast Blow; TPS-35LB response time is not specified in available data

Physical length variation (0.874" vs 1.740") does not affect functional compatibility in standard bolt-mount fuse holders, as the cartridge seats within the holder assembly.

Frequently Asked Questions (FAQ)

Q: Can the 0TLS035.TXL replace the TPS-35LB in existing installations?

A: Yes. Both parts are electrically equivalent at 35A 170 VDC with identical breaking capacity (100kA), mounting type (bolt mount), and package configuration (cylindrical blade terminal). The length difference does not affect compatibility with standard bolt-mount fuse holders.

Q: What is the significance of the length difference between these parts?

A: The TPS-35LB measures 0.874" in length while the 0TLS035.TXL measures 1.740" in length. Both fit within standard bolt-mount cartridge fuse holders. The length variation reflects internal design differences between manufacturers but does not impact electrical performance or mechanical seating in the holder.

Q: Are the approval certifications equivalent?

A: Both parts carry CE certification. The TPS-35LB carries UR approval while the 0TLS035.TXL carries cURus approval. Both certifications are recognized for telecom and industrial DC protection applications. Verify specific regulatory requirements for your application jurisdiction.

Q: Does response time affect substitution compatibility?

A: The 0TLS035.TXL is specified as Fast Blow. The TPS-35LB response time is not specified in available technical data. If response time is a critical parameter for your application, verify the TPS-35LB specification with the manufacturer before substitution.

Q: Are both parts RoHS compliant?

A: Yes. The TPS-35LB is RoHS Compliant. The 0TLS035.TXL is ROHS3 Compliant. Both meet current RoHS requirements for electronic component manufacturing.
