TPS-60V Equivalent & Substitute Parts Reference

Part Overview

The TPS-60V is a 60A 170 VDC fuse cartridge manufactured by Eaton - Bussmann Electrical Division from the Telpower® TPS series. This through-hole radial bend cylinder fuse is designed for telecom applications with a breaking capacity of 100kA at rated voltage. The product is currently obsolete, making equivalent substitute parts necessary for system maintenance, repairs, and ongoing component sourcing in legacy telecom installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TPS-60V is determined by strict equivalence across the following critical parameters:

• Current Rating: 60A (exact match required)
• Voltage Rating: 170 VDC (exact match required)
• Fuse Type: Cartridge (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial Bend Cylinder (exact match required)
• Breaking Capacity: 100kA at rated voltage (exact match required)

The two substitute parts identified—0TLS060.TXLS and 0TLS060.TXV—both meet these critical electrical and mechanical parameters. Both are manufactured by Littelfuse Inc. from the POWR-GARD® TLS series and maintain full compatibility with the original TPS-60V specification for telecom applications.

Parameter Comparison

Engineering Selection Recommendations

Both 0TLS060.TXLS and 0TLS060.TXV are direct electrical and mechanical equivalents to the TPS-60V. Selection between these two Littelfuse alternatives should be based on the following factors:

Product Status: Both substitute parts are active products with current manufacturing support, ensuring long-term availability compared to the obsolete TPS-60V.

Compliance & Certifications: Both substitutes carry CE and cURus certifications. The original TPS-60V carries CE and UR certifications. The cURus certification on the Littelfuse parts provides equivalent regulatory coverage for telecom applications.

Dimensional Compatibility: The 0TLS060.TXV maintains the closest dimensional match to the original TPS-60V (0.563" Dia x 0.877" H versus 0.563" Dia x 0.874" H), with a height difference of 0.003 inches. The 0TLS060.TXLS has a slightly longer length (0.944" L), which may require verification in space-constrained mounting applications.

RoHS Compliance: Both Littelfuse substitutes are ROHS3 compliant, providing environmental compliance advantages over the original part.

Frequently Asked Questions (FAQ)

Q: Can 0TLS060.TXLS and 0TLS060.TXV be used interchangeably in the same application?

A: Yes. Both parts meet identical electrical specifications (60A, 170 VDC, 100kA breaking capacity) and mounting requirements (through-hole, radial bend cylinder). The primary difference is physical length: 0TLS060.TXLS is 0.944" L while 0TLS060.TXV is 0.877" H. Verify available mounting space before selection.

Q: What is the significance of "Fast Blow" response time on the substitute parts?

A: Fast Blow indicates the fuse operates with rapid response to overcurrent conditions. This characteristic is not specified for the original TPS-60V but is consistent with standard cartridge fuse behavior in telecom protection circuits. This does not affect substitution compatibility.

Q: Are the Littelfuse substitutes suitable for direct replacement without circuit modification?

A: Yes. Both 0TLS060.TXLS and 0TLS060.TXV maintain full electrical equivalence (60A, 170 VDC, 100kA breaking capacity) and mechanical compatibility (through-hole mounting, radial bend cylinder package). No circuit modifications are required.

Q: How do the certifications compare between the original and substitute parts?

A: The original TPS-60V carries CE and UR certifications. The Littelfuse substitutes carry CE and cURus certifications. Both certification sets are appropriate for telecom applications. cURus provides combined UL and CSA recognition, equivalent to the UR certification on the original part.

Q: Which substitute part should be selected for space-constrained applications?

A: The 0TLS060.TXV is recommended for space-constrained applications, as it maintains the closest height match to the original TPS-60V (0.877" H versus 0.874" H, a 0.003" difference). The 0TLS060.TXLS is 0.944" L and may require additional clearance verification.
