TB200-02 Equivalent & Substitute Parts

Part Overview

The TB200-02 is a 2-circuit barrier block connector manufactured by Eaton - Bussmann Electrical Division, part of the Magnum® TB200 series. This terminal block is designed for applications requiring dual-wall barrier separation with screw termination and closed bottom configuration. The part is currently active in production with 699 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct replacement in compatible applications without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

The Curtis Industries 2002 is classified as an equivalent substitute based on the following critical parameters:

• Terminal Block Type: Both parts are barrier blocks with identical dual-wall (2 Wall) barrier configuration
• Circuit Configuration: Both feature 2 circuits with 4 wire entries and 2-row arrangement
• Pitch Tolerance: TB200-02 pitch of 0.437" (11.10mm) and 2002 pitch of 0.438" (11.12mm) represent a 0.02mm variance, within standard mechanical tolerance for barrier block connectors
• Current Rating: Both rated at 30A
• Termination Method: Both use screw-type top termination with closed bottom configuration
• Mounting: Both support chassis and panel mounting with flange feature
• Flammability: Both meet UL94 V-0 standard
• Wire Gauge Compatibility: TB200-02 accepts 12-22 AWG; 2002 accepts 10-22 AWG (overlapping range includes 12-22 AWG)

Parameter Comparison

Engineering Selection Recommendations

TB200-02 (Eaton - Bussmann) is the primary specification when:

• Operating temperature range of -40°C to 130°C is required
• Thermoplastic insulation material is specified
• 300V voltage rating is a design requirement
• Original equipment manufacturer (OEM) part continuity is prioritized

2002 (Curtis Industries) is an acceptable substitute when:

• Operating temperature does not exceed 110°C
• Polyphenylene Oxide (PPO) insulation material is acceptable for the application
• Voltage rating specification is not critical or application voltage is below 300V
• Wire gauge requirements fall within the 12-22 AWG overlap range
• Both RoHS compliance and UL94 V-0 flammability rating requirements are met

Both parts are active products with current manufacturing status and full compliance certifications. The 0.02mm pitch variance is within standard mechanical tolerance for barrier block connectors and does not affect PCB or panel mounting compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Curtis Industries 2002 be used as a direct replacement for the TB200-02 in all applications?

A: The 2002 is mechanically and electrically compatible for most applications. However, if your design operates above 110°C or requires the full -40°C to 130°C temperature range, the TB200-02 is the required choice. Verify your application's operating temperature specification before substitution.

Q: What is the significance of the 0.02mm pitch difference between these parts?

A: The pitch difference (0.437" vs 0.438") is 0.02mm and falls within standard mechanical tolerance for barrier block connectors. This variance does not affect mounting hole alignment or circuit spacing in standard PCB or panel applications.

Q: Are there any material compatibility concerns between the Thermoplastic (TB200-02) and PPO (2002) insulation materials?

A: Both materials meet UL94 V-0 flammability requirements. Material selection depends on application-specific chemical exposure, humidity, and thermal cycling requirements. Consult material datasheets if exposure to solvents or extreme humidity is expected.

Q: Does the wire gauge difference (12-22 AWG vs 10-22 AWG) affect substitution?

A: The TB200-02 specification of 12-22 AWG is fully contained within the 2002 range of 10-22 AWG. If your application uses wire gauges between 12-22 AWG, both parts are compatible. If 10 or 11 AWG wire is required, only the 2002 supports this range.

Q: What is the packaging difference between these parts?

A: TB200-02 is supplied in Bulk packaging (699 units in stock), while 2002 is supplied in Box packaging (1076 units in stock). Packaging format does not affect electrical or mechanical performance.

Q: Are both parts RoHS compliant?

A: Yes. TB200-02 is RoHS Compliant, and 2002 is ROHS3 Compliant. Both meet current RoHS requirements for electronic component manufacturing.
