Curtis Industries 6204008 Terminal Block Connector - Equivalent & Substitute Parts

Part Overview

The Curtis Industries 6204008 is a feed-through terminal block connector designed for 4-position applications with screw termination. 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 product maintains active status in the market. Substitute parts may be required due to inventory constraints, regional availability, or specific application requirements where alternative electrical or mechanical parameters are acceptable.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 2775061 is identified as a substitute for the Curtis Industries 6204008 based on the following substitution criteria:

Matching Parameters:

• 4-position feed-through terminal block configuration
• Screw termination style
• Wire gauge compatibility within overlapping range (10-24 AWG)
• 600V UL voltage rating alignment
• EAR99 ECCN classification
• REACH Unaffected status

Differing Parameters:

• Current rating: 0.5 A (IEC) / 500 mA (UL) versus 32 A (IEC) / 30 A (UL)
• Voltage rating (IEC): 500V versus 800V
• Number of levels: 1 versus 2
• Terminal width: 6.2mm versus 6.0mm
• Wire gauge upper range: 10-30 AWG versus 10-24 AWG
• Insulation material: Polyamide (PA), Nylon versus Polyamide (PA66), Nylon 6/6
• Flammability rating: UL94 V-2 versus UL94 V-0
• RoHS status: ROHS3 Compliant versus RoHS non-compliant
• Series designation: CLIPLINE UDK
• Features: LED indicator present

Substitution is valid only for applications where the lower current and voltage ratings of the 2775061 are acceptable, and where the single-level configuration meets mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

Curtis Industries 6204008 is the primary specification for applications requiring:

• High current capacity (32 A IEC / 30 A UL)
• High voltage isolation (800V IEC)
• Superior flammability performance (UL94 V-0)
• Two-level terminal configuration
• Wire gauge limitation to 10-24 AWG

Phoenix Contact 2775061 may be selected as a substitute only when:

• Application current requirements do not exceed 0.5 A (IEC) or 500 mA (UL)
• Application voltage requirements do not exceed 500V (IEC) or 600V (UL)
• Single-level terminal configuration is acceptable
• RoHS3 compliance is required
• Lower flammability rating (UL94 V-2) is acceptable for the application
• Extended wire gauge compatibility (10-30 AWG) is beneficial

Both components maintain active product status and REACH Unaffected compliance. Selection between these parts must be based on explicit application electrical and mechanical requirements.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2775061 directly replace the Curtis Industries 6204008 in all applications?

A: No. The 2775061 has significantly lower current and voltage ratings (0.5 A IEC / 500 mA UL at 500V IEC versus 32 A IEC / 30 A UL at 800V IEC). Substitution is valid only for applications where these lower ratings are acceptable. The single-level configuration also differs from the two-level design of the 6204008.

Q: What are the key electrical differences between these parts?

A: The Curtis Industries 6204008 is rated for 32 A at 800V (IEC), while the Phoenix Contact 2775061 is rated for 0.5 A at 500V (IEC). The UL voltage rating is identical at 600V, but UL current differs (30 A versus 500 mA). These differences make the 2775061 unsuitable for high-current applications.

Q: Are there mechanical compatibility concerns?

A: Yes. The 6204008 features a two-level terminal configuration with 6.0mm terminal width, while the 2775061 has a single-level configuration with 6.2mm terminal width. PCB mounting patterns and connector spacing may differ. Physical verification is required before substitution.

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

A: The Curtis Industries 6204008 carries UL94 V-0 rating (superior flame resistance), while the Phoenix Contact 2775061 carries UL94 V-2 rating (lower flame resistance). Applications in safety-critical or high-temperature environments may require the V-0 rating.

Q: Does RoHS compliance affect substitution decisions?

A: The Curtis Industries 6204008 is RoHS non-compliant, while the Phoenix Contact 2775061 is ROHS3 compliant. If RoHS3 compliance is a regulatory requirement for your application, the 2775061 is the appropriate choice, provided electrical and mechanical parameters are acceptable.

Q: What wire gauge ranges are supported?

A: The Curtis Industries 6204008 supports 10-24 AWG (0.5-4mm²). The Phoenix Contact 2775061 supports 10-30 AWG (0.2-6mm²), offering extended compatibility with finer gauge wires.
