TB200-02SP Equivalent & Substitute Parts

Part Overview

The TB200-02SP is a 2-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 and is designed for chassis and panel mounting applications requiring dual-wall barrier separation. The product is currently active and stocked with 842 units available.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct replacement in applications where the primary component is unavailable or when inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TB200-02SP is determined by strict alignment of the following critical parameters:

• Terminal block type classification as barrier block
• Identical circuit count (2 circuits)
• Matching pitch dimension (0.437" / 11.10mm)
• Identical row configuration (2 rows)
• Voltage rating of 300V or higher
• Dual-wall barrier separation
• Closed bottom termination
• Flange-mounted configuration
• UL94 V-0 flammability rating

The substitute part 1546671-2 (TE Connectivity AMP Connectors, Buchanan series) meets these core substitution criteria. Variations in current rating, wire gauge range, terminal screw material finish, and maximum operating temperature represent acceptable parameter differences within the barrier block terminal category and do not preclude substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

Both the TB200-02SP and 1546671-2 maintain active product status and comply with applicable regulatory standards. The TB200-02SP carries RoHS compliance certification, while the 1546671-2 meets ROHS3 compliance requirements. Both components are classified under identical HTSUS and ECCN codes, confirming functional equivalence within the barrier block terminal category.

The TB200-02SP supports a maximum current rating of 30A and wire gauge range of 12-22 AWG. The 1546671-2 supports 25A maximum current and 14-22 AWG wire gauge. Selection between these parts should account for application-specific current requirements and minimum wire gauge specifications. The TB200-02SP operates to 130°C maximum, while the 1546671-2 operates to 120°C maximum. Applications requiring operation above 120°C require the TB200-02SP.

Both components feature identical pitch, circuit count, row configuration, voltage rating, barrier type, and flammability rating, confirming mechanical and electrical interchangeability within these parameter boundaries.

Frequently Asked Questions (FAQ)

Q: Can the 1546671-2 directly replace the TB200-02SP in all applications?

A: The 1546671-2 is substitutable where application current requirements do not exceed 25A, minimum wire gauge is 14 AWG or larger, and maximum operating temperature does not exceed 120°C. The TB200-02SP is required for applications exceeding these limits.

Q: What are the key differences between these two barrier block connectors?

A: The primary differences are current rating (30A vs. 25A), wire gauge range (12-22 AWG vs. 14-22 AWG), maximum operating temperature (130°C vs. 120°C), and terminal screw finish (zinc vs. nickel). All other electrical and mechanical parameters are identical.

Q: Are both parts mechanically compatible with the same mounting footprint?

A: Yes. Both components share identical pitch (0.437"), circuit count (2), row configuration (2), and flange-mounted design, confirming mechanical interchangeability for chassis and panel mounting applications.

Q: Do both parts meet the same flammability and compliance standards?

A: Yes. Both the TB200-02SP and 1546671-2 carry UL94 V-0 flammability ratings and are classified under identical HTSUS and ECCN codes. The TB200-02SP is RoHS compliant, while the 1546671-2 is ROHS3 compliant.

Q: What wire gauge considerations apply when substituting between these parts?

A: The TB200-02SP accommodates 12-22 AWG wire, while the 1546671-2 accommodates 14-22 AWG wire. Applications using 12 AWG wire require the TB200-02SP. Both parts support 14-22 AWG wire without restriction.

Q: How do the current ratings affect substitution decisions?

A: The TB200-02SP is rated for 30A maximum current, while the 1546671-2 is rated for 25A maximum current. Applications requiring current capacity above 25A must use the TB200-02SP. Applications operating at or below 25A can use either part.
