TB200-08 Equivalent & Substitute Parts

Part Overview

The TB200-08 is an 8-circuit barrier block connector manufactured by Eaton - Bussmann Electrical Division as part of the Magnum® TB200 series. This terminal block is designed for chassis and panel mounting applications requiring dual-wall barrier separation and screw-based termination. The part is currently active in production with 961 units in stock.

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

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TB200-08 is determined by the following critical parameters:

Electrical Compatibility:

• 8 circuits with 16 wire entries
• 30A current rating
• Dual-wall barrier configuration
• Screw-based top termination with closed bottom termination

Mechanical Compatibility:

• 2-row configuration
• Chassis and panel mounting capability
• UL94 V-0 flammability rating

Acceptable Variance:

• Pitch tolerance: 0.437" to 0.438" (11.10mm to 11.12mm) represents standard manufacturing tolerance
• Wire gauge range: Substitute must accommodate the main part's 12-22 AWG specification or broader range
• Operating temperature: Substitute minimum rating must support the main part's operating range

The Curtis Industries 2008 meets these substitution criteria through equivalent circuit count, current rating, barrier configuration, and termination method.

Parameter Comparison

Engineering Selection Recommendations

TB200-08 (Eaton - Bussmann):

• Primary selection for applications requiring 300V voltage rating specification
• RoHS Compliant status with thermoplastic insulation material
• Operating temperature range: -40°C to 130°C
• Zinc-finished steel terminal screws
• Active production status with established supply chain

2008 (Curtis Industries):

• Equivalent substitute when voltage rating specification is not a limiting factor
• ROHS3 Compliant with Polyphenylene Oxide (PPO) insulation material
• Operating temperature range: up to 110°C
• Wire gauge accommodation extends to 10 AWG (broader than TB200-08)
• Active production status with alternative supply availability

Both parts satisfy the core electrical and mechanical requirements for 8-circuit barrier block applications with 30A current capacity and dual-wall barrier separation. Selection between these parts should be based on specific application voltage requirements, insulation material compatibility, and temperature operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the Curtis Industries 2008 replace the TB200-08 in all applications?

A: The 2008 is electrically and mechanically compatible for applications operating at or below the specified voltage rating of the substitute part. Verify that your application does not require the 300V rating specified for the TB200-08. Both parts support identical circuit count, current rating, and barrier configuration.

Q: What is the significance of the pitch difference between 0.437" and 0.438"?

A: The 0.001" (0.02mm) difference falls within standard manufacturing tolerance for terminal block connectors. This variance does not affect electrical performance or mechanical mounting compatibility in standard chassis and panel applications.

Q: Are there wire gauge limitations when substituting?

A: The TB200-08 accommodates 12-22 AWG wire. The 2008 accommodates 10-22 AWG wire, providing a broader range. When substituting, ensure your application wire gauge falls within both specifications or verify that the substitute's broader range is acceptable for your design.

Q: What is the difference between thermoplastic and PPO insulation materials?

A: Both materials are UL94 V-0 rated for flammability. Thermoplastic (TB200-08) and Polyphenylene Oxide (2008) differ in chemical resistance and temperature stability. Verify material compatibility with your specific application environment and any chemical exposure requirements.

Q: Does the operating temperature range affect substitution eligibility?

A: The TB200-08 operates from -40°C to 130°C. The 2008 operates to 110°C. If your application requires operation below -40°C or above 110°C, the 2008 is not suitable. For applications within the 2008's range, both parts are compatible.

Q: What packaging differences exist between these parts?

A: TB200-08 is supplied in bulk packaging with 961 units in stock. The 2008 is supplied in box packaging with 1541 units in stock. Packaging format does not affect electrical or mechanical compatibility; it reflects supplier inventory and distribution methods.

Q: Are both parts RoHS compliant?

A: Yes. The TB200-08 is RoHS Compliant. The 2008 is ROHS3 Compliant. Both meet RoHS requirements for hazardous substance restrictions. The 2008 additionally carries REACH Unaffected status.
