TPS-35L Equivalent & Substitute Parts Reference

Part Overview

The TPS-35L 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 actively produced and stocked, with 738 units available in inventory. Equivalent and substitute parts are identified based on matching electrical specifications, mechanical compatibility, and regulatory compliance to support procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

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

• Current Rating: 35A (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)
• Regulatory Compliance: CE and UR certifications (minimum requirement)

The substitute part 0TLS035.TXL from Littelfuse Inc. meets all critical electrical and mechanical parameters. Both components are actively produced, RoHS compliant, and approved for telecom applications.

Parameter Comparison

Engineering Selection Recommendations

The 0TLS035.TXL from Littelfuse Inc. is a qualified substitute for the TPS-35L based on electrical and mechanical parameter equivalence. Both components are actively produced and carry relevant regulatory certifications (CE and UR/cURus). The substitute part maintains identical current rating, voltage rating, breaking capacity, and mounting configuration.

Physical dimension differences exist in the length specification (0.874" versus 1.740"), which must be evaluated against the mechanical constraints of the target application and mounting footprint. The substitute part's Fast Blow response time characteristic is supplementary information not specified for the primary part and should be cross-referenced with application requirements if response time is a critical design parameter.

Both components are RoHS compliant and suitable for telecom applications. Selection between these parts should be based on availability, lead time, cost considerations, and confirmation that the dimensional variation does not conflict with the installation environment.

Frequently Asked Questions (FAQ)

Q: Can the 0TLS035.TXL replace the TPS-35L in all applications?

A: The 0TLS035.TXL matches all critical electrical parameters (35A, 170 VDC, 100kA breaking capacity) and mounting type (bolt mount, cylindrical cartridge). However, the physical length differs (1.740" versus 0.874"). Verify that the mounting cavity and clearance space accommodate the longer substitute part before installation.

Q: Are there differences in regulatory compliance between these parts?

A: Both parts carry CE certification. The TPS-35L is certified by UR; the 0TLS035.TXL is certified by cURus. Both certifications are recognized for telecom applications. Confirm that your specific application requirements accept cURus certification in place of UR if this distinction is material to your compliance documentation.

Q: What does "Fast Blow" response time mean for the 0TLS035.TXL?

A: Fast Blow indicates the fuse responds quickly to overcurrent conditions. The TPS-35L does not specify a response time characteristic in the provided data. If your application requires a specific response time profile, cross-reference the detailed specifications of both parts with your circuit protection requirements.

Q: Are both parts currently available?

A: Yes. The TPS-35L has 738 units in stock; the 0TLS035.TXL has 1023 units in stock. Both are listed as active products.

Q: What is the significance of the RoHS3 designation for the substitute part?

A: ROHS3 Compliant indicates compliance with the latest RoHS directive requirements. The TPS-35L is listed as RoHS Compliant. Both designations satisfy RoHS requirements; ROHS3 represents a more recent compliance standard. This does not affect electrical or mechanical substitution eligibility.
