CBP-5 Equivalent & Substitute Parts Reference

Part Overview

The CBP-5 is a 5-circuit barrier block connector manufactured by Curtis Industries, designed for applications requiring screw-terminated connections with dual-wall barrier isolation. This component is classified as Active product status with full RoHS3 compliance and UL94 V-0 flammability rating. Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, enabling component procurement flexibility while maintaining circuit integrity and safety standards.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CBP-5 are identified based on the following critical parameters that determine functional equivalence:

• Circuit Configuration: Number of circuits (5) and pitch spacing (0.375"/9.53mm) must match to ensure mechanical compatibility with existing PCB layouts and connector housings.
• Termination Type: Both top (screw) and bottom (PC pin) termination methods must be identical to maintain assembly compatibility.
• Barrier Isolation: Dual-wall (2 Wall) barrier type ensures equivalent electrical isolation between circuits.
• Wire Gauge Compatibility: Acceptable wire gauge range (12-22 AWG) must overlap to support existing wiring specifications.
• Regulatory Compliance: RoHS3 compliance and UL94 V-0 flammability rating are mandatory for equivalent substitution.

The LP202205 (Eaton - Electronics Division) meets these core substitution criteria. Variations in current rating, voltage rating, operating temperature range, and terminal screw finish do not preclude substitution when application requirements fall within the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

Selection between CBP-5 and LP202205 is determined by application voltage and current requirements:

CBP-5 (Curtis Industries): Select when application voltage exceeds 150V and current requirements do not exceed 20A. This part provides higher voltage margin for industrial control and power distribution applications.

LP202205 (Eaton - Electronics Division): Select when application current exceeds 20A but does not exceed 30A, and application voltage does not exceed 150V. This part provides higher current capacity for signal distribution and lower-voltage switching applications.

Both parts maintain identical mechanical compatibility, termination methods, circuit configuration, and regulatory compliance (RoHS3, UL94 V-0). Selection is based solely on electrical parameter alignment with application specifications.

Frequently Asked Questions (FAQ)

Q: Can LP202205 be used as a direct replacement for CBP-5 in all applications?

A: LP202205 is mechanically and electrically compatible with CBP-5 when application voltage does not exceed 150V. If your application requires voltage operation above 150V, CBP-5 is the required selection. Both parts support identical wire gauges (12-22 AWG) and circuit configurations (5 circuits at 0.375" pitch).

Q: What is the significance of the pitch specification (0.375")?

A: Pitch defines the center-to-center spacing between circuits. Both CBP-5 and LP202205 maintain 0.375" (9.53mm) pitch, ensuring mechanical compatibility with PCB layouts and connector housings designed for this spacing. Pitch mismatch prevents proper installation.

Q: Are there differences in mounting compatibility?

A: CBP-5 supports Chassis and Panel mounting with Through Hole configuration. LP202205 supports Through Hole mounting only. Verify your application mounting method before substitution.

Q: What does "2 Wall (Dual) Barrier Type" mean?

A: Dual-wall barrier construction provides electrical isolation between adjacent circuits through two separate insulation walls. Both CBP-5 and LP202205 incorporate this design, ensuring equivalent circuit isolation and safety performance.

Q: How do the current ratings (20A vs. 30A) affect substitution?

A: LP202205 has a higher current rating (30A) than CBP-5 (20A). If your application current requirement is 20A or less, LP202205 can be substituted. If your application requires current above 20A but below 30A, only LP202205 is suitable. If your application requires current above 30A, neither part is appropriate.

Q: What is the impact of the voltage rating difference (300V vs. 150V)?

A: CBP-5 is rated for 300V operation; LP202205 is rated for 150V. If your application operates above 150V, CBP-5 must be used. If your application operates at or below 150V, both parts are suitable from a voltage perspective.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both CBP-5 and LP202205 are RoHS3 compliant and carry UL94 V-0 flammability certification, meeting identical regulatory requirements for industrial and commercial applications.
