CB20720607 Equivalent & Substitute Parts

Part Overview

The CB20720607 is a 6-circuit barrier block connector manufactured by Eaton Electronics Division, part of the Magnum® CB2000 series. This through-hole terminal block features 0.375" (9.53mm) pitch spacing and is designed for applications requiring screw termination with captive plate assembly on the top and PC pin connections on the bottom. The component is actively produced and maintained in inventory, serving as a standard interconnection solution in industrial control and power distribution applications. Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when design flexibility permits cross-platform component selection.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CB20720607 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Circuits: 6
• Pitch: 0.375" (9.53mm)
• Voltage Rating: 300V
• Wire Gauge Compatibility: 12-22 AWG
• Barrier Type: 3 Wall (Tri)
• Top Termination: Screws with Captive Plate
• Flammability Rating: UL94 V-0
• Mounting Type: Through Hole

Allowable Variation Parameters:

• Current Rating: Substitute must meet or exceed 30A requirement
• Bottom Termination: May differ (PC Pin vs. Wire Wrap)
• Operating Temperature: Substitute minimum must support -40°C to 105°C range
• Terminal Screw Finish: May vary (Zinc vs. Zinc with Clear Chromate)

The identified substitute part 6WWV-06-008 from TE Connectivity AMP Connectors meets all mandatory matching criteria and operates within allowable variation parameters, making it a valid equivalent for the CB20720607 in applications where bottom termination flexibility exists.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (CB20720607): The CB20720607 remains the preferred choice for applications requiring the full 30A current rating and PC pin bottom termination. Active product status and ROHS3 compliance ensure continued availability and regulatory alignment. This part is suitable for new designs and applications where the Magnum® CB2000 series integration is specified.

Substitute Part Selection (6WWV-06-008): The 6WWV-06-008 from TE Connectivity is a valid substitute when the following conditions are met:

• Application current requirements do not exceed 25A
• Wire wrap bottom termination is compatible with the PCB or assembly design
• TE Connectivity AMP Connectors sourcing is acceptable within supply chain strategy

Both parts maintain UL94 V-0 flammability certification and RoHS compliance, ensuring regulatory requirements are satisfied in either configuration. The enhanced terminal screw finish (Zinc with Clear Chromate) on the substitute part provides additional corrosion resistance in certain environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the 6WWV-06-008 be used as a direct replacement for CB20720607 in all applications?

A: The 6WWV-06-008 is functionally equivalent for applications operating at 25A or below. The primary difference is bottom termination type: PC pin versus wire wrap. PCB layout and assembly process compatibility must be verified before substitution.

Q: What is the significance of the current rating difference (30A vs. 25A)?

A: The CB20720607 is rated for 30A continuous current, while the 6WWV-06-008 is rated for 25A. Applications requiring the full 30A capacity must use the CB20720607. Applications operating below 25A can safely use either part.

Q: Are both parts suitable for the same operating temperature range?

A: The CB20720607 specifies -40°C to 105°C. The 6WWV-06-008 specifies 105°C as the maximum. For applications requiring operation below 0°C, the CB20720607 is the appropriate choice.

Q: Do both parts meet the same regulatory and compliance standards?

A: Both parts are UL94 V-0 rated and RoHS compliant. The CB20720607 carries ROHS3 certification, while the 6WWV-06-008 carries standard RoHS certification. Both satisfy current regulatory requirements for their respective markets.

Q: What is the difference between PC pin and wire wrap termination?

A: PC pin termination uses through-hole pins inserted into PCB holes. Wire wrap termination uses wrapped wire connections. The choice depends on the PCB design and assembly process. Verify compatibility with your specific application before substitution.

Q: Can these parts be intermixed in the same assembly?

A: Both parts share identical pitch (0.375"), circuit count (6), and barrier configuration. However, mixing termination types (PC pin and wire wrap) in a single assembly requires careful PCB design verification to ensure proper mechanical and electrical integration.
