TB200-06SP Equivalent & Substitute Parts

Part Overview

The TB200-06SP is a 6-circuit barrier block connector manufactured by Eaton - Bussmann Electrical Division, part of the Magnum® TB200 series. This terminal block features a 0.437" (11.10mm) pitch with dual-wall barrier construction and is designed for chassis and panel mounting applications. The component is currently active in production with 922 units in stock. Equivalent and substitute parts are identified when component availability is constrained, supply chain disruptions occur, or design flexibility permits selection from qualified alternatives that meet the same electrical and mechanical requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TB200-06SP is determined by strict alignment of the following core parameters:

Critical Matching Parameters:

• Terminal block type: Barrier block
• Number of circuits: 6
• Pitch: 0.437" (11.10mm)
• Number of rows: 2
• Barrier type: 2 Wall (Dual)
• Bottom termination: Closed
• Voltage rating: 300V
• Flammability rating: UL94 V-0
• RoHS compliance: Required

Allowable Variation Parameters:

• Current rating: Substitute must meet or exceed 30A requirement
• Wire gauge: Substitute must accommodate 12-22 AWG minimum
• Operating temperature: Substitute must support -40°C ~ 130°C range
• Top termination style: Screws (with or without captive plate)
• Terminal screw material and finish: Steel or equivalent

The substitute part 1546671-6 (TE Connectivity AMP Connectors, Buchanan series) meets the critical matching parameters. However, the current rating of 25A is below the 30A specification of the main part, and the wire gauge range (14-22 AWG) does not accommodate 12 AWG. These differences must be evaluated against application requirements.

Parameter Comparison

Engineering Selection Recommendations

The TB200-06SP and 1546671-6 share identical mechanical form factors (6 circuits, 0.437" pitch, 2-row configuration) and both meet UL94 V-0 flammability and RoHS compliance requirements. Both components are active products with current manufacturing status.

Selection between these parts must account for the following parameter differences:

Current Rating Differential: The TB200-06SP is rated for 30A while the 1546671-6 is rated for 25A. Applications requiring the full 30A capacity cannot use the TE Connectivity substitute without circuit redesign or parallel connection configurations.

Wire Gauge Accommodation: The TB200-06SP accepts 12-22 AWG wire, while the 1546671-6 accepts 14-22 AWG. Applications using 12 AWG conductors require the Eaton part.

Operating Temperature Range: The TB200-06SP operates to 130°C maximum, while the 1546671-6 operates to 120°C maximum. High-temperature applications above 120°C require the Eaton component.

Termination Configuration: The TB200-06SP includes a captive plate on the screw termination, while the 1546671-6 uses standard screws. This affects assembly procedures and may impact vibration resistance in certain mounting orientations.

Terminal Finish: Zinc-plated terminals (TB200-06SP) and nickel-plated terminals (1546671-6) have different corrosion resistance profiles in specific environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can 1546671-6 be used as a direct replacement for TB200-06SP in all applications?

A: No. The 1546671-6 has three limiting factors: 25A current rating (versus 30A), 14-22 AWG wire gauge range (versus 12-22 AWG), and 120°C maximum temperature (versus 130°C). Use is restricted to applications that do not require these higher specifications.

Q: What is the significance of the captive plate on the TB200-06SP?

A: The captive plate on the screw termination prevents screw loss during assembly and provides additional mechanical retention. The 1546671-6 uses standard screws without this feature, requiring different assembly procedures.

Q: Are both parts physically interchangeable on a PCB or mounting surface?

A: Yes, both parts share identical pitch (0.437"), circuit count (6), row configuration (2), and mounting footprint. Physical mounting is compatible. However, electrical performance differences must be evaluated for the specific application.

Q: What environmental conditions favor one part over the other?

A: The TB200-06SP is preferred for high-temperature environments (above 120°C) and applications requiring 12 AWG wire accommodation. The 1546671-6 is suitable for standard industrial environments within its 25A and 120°C limits.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the TB200-06SP and 1546671-6 are UL94 V-0 rated and RoHS compliant, meeting identical flammability and hazardous substance requirements.

Q: What is the inventory status for each part?

A: TB200-06SP has 922 units in stock. 1546671-6 has 3509 units in stock. Availability may influence selection in time-sensitive procurement scenarios.
