Curtis Industries 6204003 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Curtis Industries 6204003 is a feed-through terminal block connector designed for 4-position applications with 2-level configuration. This component is rated for 32 A (IEC) / 30 A (UL) at 800V (IEC) / 600V (UL) and accommodates wire gauges from 10-24 AWG (0.5-4mm²). The part maintains active product status and is currently in stock with 819 units available. Alternative components may be required due to application-specific requirements, supply chain considerations, or design modifications necessitating different electrical or mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 2775061 is identified as a substitute for the Curtis Industries 6204003 based on the following alignment criteria:

Common Functional Parameters:

• Feed-through terminal block configuration
• 4-position connector design
• Screw termination style
• Wire gauge compatibility within overlapping range (10-24 AWG for main part; 10-30 AWG for substitute)
• Voltage rating compatibility at UL standard (600V)
• Polyamide-based insulation material

Substitution Constraints: The 2775061 operates at significantly reduced current capacity (0.5 A IEC / 500 mA UL) compared to the 6204003 (32 A IEC / 30 A UL). This substitute is suitable only for applications where current requirements do not exceed the lower rating. The substitute features a single-level configuration versus the two-level design of the main part, and includes LED functionality not present in the original component.

Parameter Comparison

Engineering Selection Recommendations

Curtis Industries 6204003 is the primary selection for applications requiring high current capacity (30-32 A range) and enhanced flammability performance (UL94 V-0). This part maintains active product status with established inventory availability.

Phoenix Contact 2775061 serves as a substitute only in low-current applications where current demand does not exceed 500 mA (UL) or 0.5 A (IEC). This substitute offers RoHS3 compliance, which may be mandated by specific regulatory frameworks. The single-level configuration and reduced voltage rating (500V IEC) must be verified against application requirements before implementation.

Both components maintain active product status and are available in stock. Selection between these parts depends on current requirements, compliance mandates, and mechanical space constraints related to level configuration.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2775061 replace the Curtis Industries 6204003 in all applications?

A: No. The 2775061 is limited to applications with maximum current requirements of 500 mA (UL) or 0.5 A (IEC). The original 6204003 is rated for 30 A (UL) or 32 A (IEC). Substitution is valid only when application current demand falls within the lower rating.

Q: What are the key differences in mechanical configuration?

A: The 6204003 features a 2-level configuration with 6.0mm terminal width, while the 2775061 provides a single-level design with 6.2mm terminal width. These differences may affect PCB layout and mounting requirements.

Q: Does the Phoenix Contact 2775061 meet RoHS requirements?

A: Yes. The 2775061 is ROHS3 compliant. The Curtis Industries 6204003 is RoHS non-compliant. If RoHS compliance is a design requirement, the 2775061 is the appropriate selection, provided current ratings are acceptable.

Q: Are the wire gauge ranges compatible?

A: The wire gauge ranges overlap. The 6204003 accommodates 10-24 AWG (0.5-4mm²), while the 2775061 accommodates 10-30 AWG (0.2-6mm²). Both parts accept 10-24 AWG wire, ensuring compatibility within this range.

Q: What is the significance of the flammability rating difference?

A: The 6204003 carries UL94 V-0 rating, indicating superior flame resistance. The 2775061 carries UL94 V-2 rating, which is less stringent. Applications in high-temperature or flame-sensitive environments should prioritize the V-0 rated component.

Q: Are both parts currently available?

A: Yes. The Curtis Industries 6204003 has 819 units in stock. The Phoenix Contact 2775061 has 928 units in stock. Both maintain active product status.
