Curtis Industries 6204009 Terminal Block Connector - Equivalent & Substitute Parts

Part Overview

The Curtis Industries 6204009 is a feed-through terminal block connector rated for 4 positions across 2 levels, designed for wire gauges 10-24 AWG (0.5-4mm²). This component operates at 32 A (IEC) / 30 A (UL) and 800V (IEC) / 600V (UL), utilizing screw termination with polyamide insulation rated UL94 V-0. The part is currently active in production with 921 units in stock. Equivalent and substitute parts are identified when operational parameters fall within acceptable ranges for the intended application, accounting for variations in current capacity, voltage rating, wire gauge compatibility, and physical dimensions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for terminal block connectors is determined by compatibility across the following critical parameters:

Position and Level Configuration: The substitute part must maintain the same number of positions (4) and support equivalent connection architecture. The main part operates with 2 levels; substitutes with 1 level remain functionally compatible for feed-through applications where level separation is not a circuit requirement.

Electrical Ratings: Substitute parts must meet or exceed the voltage and current requirements of the application. The main part specifies 32 A (IEC) and 800V (IEC). Substitutes with lower current ratings (0.5 A IEC) are not suitable for high-current applications but may serve in signal-level or low-power circuits.

Wire Gauge Compatibility: The main part accommodates 10-24 AWG (0.5-4mm²). Substitutes with expanded wire gauge ranges (10-30 AWG, 0.2-6mm²) provide broader compatibility and can accept the main part's wire specifications.

Termination Method: Both the main part and identified substitutes use screw termination, ensuring mechanical and electrical compatibility.

Physical Dimensions: Terminal width variations (6.0mm vs. 6.2mm) are within acceptable tolerance for feed-through applications and do not prevent substitution.

Phoenix Contact 2775061 qualifies as a substitute based on matching position count (4), screw termination, overlapping wire gauge range, and equivalent voltage rating (600V UL). The reduced current capacity (0.5 A IEC) limits its application to low-current circuits.

Parameter Comparison

Engineering Selection Recommendations

Curtis Industries 6204009 is the primary specification for applications requiring 32 A (IEC) / 30 A (UL) current capacity and 800V (IEC) operation. The UL94 V-0 flammability rating provides superior flame resistance. This part is RoHS non-compliant and remains the appropriate choice for legacy systems or applications where RoHS compliance is not mandated.

Phoenix Contact 2775061 serves as a substitute only for low-current applications operating at signal levels or control voltages where current demand does not exceed 0.5 A (IEC) or 500 mA (UL). This part offers ROHS3 compliance, making it suitable for applications subject to RoHS3 regulatory requirements. The UL94 V-2 flammability rating is lower than the main part and must be evaluated against application safety standards. The expanded wire gauge range (10-30 AWG) accommodates finer conductors. The single-level architecture differs from the main part's two-level design.

Selection between these parts depends on current requirements, regulatory compliance mandates, and flammability specifications. Direct substitution is not appropriate for high-current applications.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 2775061 replace Curtis Industries 6204009 in a 30 A circuit?

A: No. The Phoenix Contact 2775061 is rated for 0.5 A (IEC) / 500 mA (UL), which is insufficient for 30 A applications. Use only for low-current signal or control circuits.

Q: What is the significance of the level difference (2 levels vs. 1 level)?

A: The Curtis Industries 6204009 provides two-level terminal configuration, allowing stacked connections. The Phoenix Contact 2775061 operates with a single level. For feed-through applications where level separation is not required, this difference does not prevent substitution.

Q: Are the wire gauge ranges compatible?

A: Yes. The Curtis Industries 6204009 accepts 10-24 AWG (0.5-4mm²). The Phoenix Contact 2775061 accepts 10-30 AWG (0.2-6mm²), which encompasses the main part's range. Both parts can accommodate the same wire sizes within the 10-24 AWG specification.

Q: What does the flammability rating difference mean?

A: Curtis Industries 6204009 carries UL94 V-0 rating, indicating superior flame resistance and self-extinguishing properties. Phoenix Contact 2775061 carries UL94 V-2 rating, which allows limited flame propagation. Applications requiring higher flame resistance must use the Curtis Industries part.

Q: Does RoHS compliance affect substitution?

A: RoHS compliance is a regulatory and procurement consideration, not a functional compatibility factor. Curtis Industries 6204009 is RoHS non-compliant; Phoenix Contact 2775061 is ROHS3 compliant. Selection depends on regulatory requirements applicable to the end application or market.

Q: Are the terminal width differences (6.0mm vs. 6.2mm) significant?

A: The 0.2mm difference is within acceptable tolerance for feed-through terminal block applications and does not prevent mechanical or electrical substitution.

Q: What is the stripping length difference (10mm vs. 8mm)?

A: Stripping length refers to the exposed conductor length required for termination. The Curtis Industries 6204009 requires 10mm; the Phoenix Contact 2775061 requires 8mm. Wire preparation procedures must be adjusted accordingly for each part.
