Key Parameters

Substitute Part Grouping Explanation

Substitution of the CB50420207 is based on electrical and mechanical compatibility within the Eaton Magnum® barrier block family. The following parameters must remain consistent for direct substitution:

• Terminal block type: Barrier block configuration
• Circuit count: 2 circuits
• Pitch spacing: 0.250" (6.35mm)
• Current rating: 10A minimum
• Voltage rating: 300V minimum
• Termination method: Screws with captive plate (top) and wire wrap (bottom)
• Barrier configuration: 3 wall (tri) barrier
• Flammability rating: UL94 V-0

The CB00420207 from the Magnum® CB0 series meets these substitution criteria while offering active product status and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The CB00420207 serves as the active equivalent for the obsolete CB50420207. Both components share identical electrical specifications (10A, 300V), circuit configuration (2-circuit), pitch spacing (0.250"), and termination methods (screw with captive plate and wire wrap).

The CB00420207 offers the following advantages:

• Active product status ensures continued availability and manufacturing support
• Extended operating temperature range (-40°C ~ 120°C versus -40°C ~ 105°C)
• Wider wire gauge acceptance (16-30 AWG versus 18-30 AWG)
• Polyamide (PA66) nylon insulation material versus thermoplastic

Both components maintain UL94 V-0 flammability rating and are non-RoHS compliant. The primary difference in mounting type (through hole for CB00420207 versus chassis/panel for CB50420207) must be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the CB00420207 directly replace the CB50420207 in existing applications?

A: The CB00420207 provides electrical and mechanical compatibility based on matching circuit count, pitch spacing, current rating, voltage rating, and termination configuration. Mounting type differences must be assessed for specific installation requirements.

Q: What is the significance of the wire gauge range difference?

A: The CB00420207 accepts 16-30 AWG wire, while the CB50420207 accepts 18-30 AWG. The CB00420207 accommodates larger gauge conductors (16 AWG), providing broader application flexibility.

Q: How do the insulation materials differ between these parts?

A: The CB50420207 uses thermoplastic insulation, while the CB00420207 uses Polyamide (PA66) nylon 6/6. Both materials achieve UL94 V-0 flammability rating. The nylon material in the CB00420207 offers enhanced thermal stability, supporting the extended operating temperature range.

Q: What is the impact of the operating temperature range difference?

A: The CB00420207 operates from -40°C to 120°C, compared to -40°C to 105°C for the CB50420207. This 15°C extension provides additional thermal margin for high-temperature applications.

Q: Are there RoHS compliance considerations?

A: Both the CB50420207 and CB00420207 are RoHS non-compliant. Applications requiring RoHS-compliant components must identify alternative solutions outside this product family.

Q: What mounting configuration differences exist?

A: The CB50420207 supports chassis and panel mounting, while the CB00420207 is configured for through-hole mounting. Installation method compatibility must be confirmed for the target application.
