TB200-15 Equivalent & Substitute Parts

Part Overview

The TB200-15 is a 15-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 780 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are available from alternative manufacturers, enabling procurement flexibility while maintaining functional compatibility within the specified operating envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TB200-15 is determined by strict equivalence across the following parameters:

Critical Electrical Parameters:

• Number of circuits (15)
• Current rating (30A minimum)
• Voltage rating (300V minimum)
• Wire gauge compatibility (12-22 AWG or broader range)

Critical Mechanical Parameters:

• Pitch tolerance (0.437" ± acceptable tolerance)
• Number of rows (2)
• Barrier type (2 Wall dual barrier)
• Terminal block type (Barrier Block)
• Termination method (Screw-based top termination, closed bottom)
• Mounting configuration (Chassis and Panel compatible)

Critical Compliance Parameters:

• UL94 V-0 flammability rating
• RoHS compliance status

The Curtis Industries 2015 is grouped as an equivalent substitute based on matching all critical electrical and mechanical parameters within acceptable engineering tolerances. Minor variations in insulation material, operating temperature upper limit, and screw finish specifications do not preclude functional substitution when application requirements fall within the overlapping operational envelope.

Parameter Comparison

Engineering Selection Recommendations

TB200-15 (Eaton - Bussmann) is the primary specification. Selection of this part is appropriate when:

• Operating temperature range of -40°C to 130°C is required
• Voltage rating specification of 300V is a documented requirement
• Thermoplastic insulation material is specified
• Zinc-finished steel screws are required
• Original equipment manufacturer (OEM) part continuity is prioritized

2015 (Curtis Industries) is an acceptable substitute when:

• Operating temperature does not exceed 110°C
• Wire gauge range of 10-22 AWG accommodates the application (broader than TB200-15)
• Polyphenylene Oxide (PPO) insulation material is acceptable
• RoHS3 compliance is required
• Alternative sourcing is necessary for procurement or inventory management
• Pitch tolerance of 0.438" (11.12mm) is within mechanical design allowance

Both parts maintain UL94 V-0 flammability certification and active production status, supporting long-term availability and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can the Curtis Industries 2015 be used as a direct replacement for the TB200-15 in all applications?

A: The 2015 is functionally equivalent for applications where operating temperature does not exceed 110°C. The TB200-15 supports operation to 130°C. If your application requires the full -40°C to 130°C range, the TB200-15 is the appropriate selection. For applications within the 110°C limit, the 2015 is compatible.

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

A: The pitch difference of 0.01mm (0.0004 inches) is within standard mechanical tolerances for terminal block mounting. Both parts are compatible with standard DIN rail and chassis mounting configurations. This tolerance variation does not affect electrical performance or mechanical fit in typical applications.

Q: Are there voltage rating differences between these parts?

A: The TB200-15 specifies a 300V voltage rating. The Curtis Industries 2015 does not provide a voltage specification in the available data. For applications requiring documented 300V rating compliance, the TB200-15 is the specified part. For applications operating below 300V, the 2015 may be acceptable pending application-specific voltage requirements.

Q: How do the insulation materials differ?

A: The TB200-15 uses Thermoplastic insulation, while the 2015 uses Polyphenylene Oxide (PPO). Both materials are thermoplastic polymers with UL94 V-0 flammability ratings. PPO offers slightly different thermal and chemical resistance characteristics. Material selection should align with specific environmental exposure conditions in your application.

Q: What is the wire gauge compatibility difference?

A: The TB200-15 accepts 12-22 AWG wire, while the 2015 accepts 10-22 AWG wire. The Curtis Industries part accommodates larger gauge conductors (10 AWG and 11 AWG). If your application requires termination of 10 or 11 AWG conductors, the 2015 provides this capability. For 12-22 AWG applications, both parts are compatible.

Q: Are both parts RoHS compliant?

A: Yes. The TB200-15 is RoHS Compliant, and the 2015 is ROHS3 Compliant. Both meet current RoHS requirements. ROHS3 represents the current regulatory standard, while RoHS Compliant indicates earlier compliance designation. Both are acceptable for RoHS-regulated applications.

Q: What is the inventory status for each part?

A: The TB200-15 has 780 units in stock. The Curtis Industries 2015 has 1502 units in stock. The 2015 offers higher inventory availability for immediate procurement needs.

Q: Can these parts be intermixed in a multi-circuit assembly?

A: Both parts are mechanically and electrically compatible for use in the same assembly provided that all application requirements (temperature range, voltage rating, wire gauge) fall within the overlapping specifications of both parts. Mixing should be documented in assembly procedures to ensure traceability.
