Equivalent & Substitute Parts for CB20720707

Part Overview

The CB20720707 is a 7-circuit barrier block connector manufactured by Eaton - Electronics Division, part of the Magnum® CB2000 series. This terminal block features 0.375" (9.53mm) pitch spacing with screw termination and captive plate design for top connection and PC pin bottom termination. The component is actively produced and maintained in inventory, serving applications requiring reliable electrical distribution across multiple circuits with 30A current capacity at 300V rating.

Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when procurement requirements necessitate qualified alternatives meeting equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CB20720707 is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Terminal block type: Barrier block configuration
• Number of circuits: 7 circuits
• Pitch spacing: 0.375" (9.53mm)
• Number of rows: Single row
• Voltage rating: 300V minimum
• Wire gauge compatibility: 12-22 AWG
• Top termination method: Screws with captive plate
• Barrier configuration: 3 wall (tri) barrier
• Flammability rating: UL94 V-0
• Mounting configuration: Through hole

Allowable Variation Parameters:

• Current rating: Substitute may be rated at lower amperage if application requirements permit
• Bottom termination: PC pin or wire wrap configurations are functionally equivalent for circuit completion
• Operating temperature range: Substitute may have different upper temperature limit if application environment is compatible
• Terminal screw finish: Variations in plating (zinc, clear chromate) are acceptable
• Manufacturer identity: Different qualified manufacturers permitted

The substitute part 6WWV-07-008 from TE Connectivity AMP Connectors meets all mandatory matching parameters and is therefore qualified as an equivalent substitute.

Engineering Selection Recommendations

CB20720707 (Eaton - Electronics Division):

• Primary selection for applications requiring 30A current capacity
• Active product status with 630 units in current inventory
• ROHS3 compliant for regulatory requirements
• Suitable for operating environments from -40°C to 105°C

6WWV-07-008 (TE Connectivity AMP Connectors):

• Qualified substitute when CB20720707 is unavailable
• Current rating of 25A accommodates applications within this amperage specification
• Active product status with 5151 units in current inventory
• RoHS compliant for regulatory requirements
• Wire wrap bottom termination provides alternative PCB connection method
• Operating temperature range extends to 105°C maximum
• MSL rating of 1 (Unlimited) indicates no moisture sensitivity restrictions

Selection Criteria:

• If application current requirement is 25A or less, 6WWV-07-008 is functionally equivalent
• If application requires 30A current capacity, CB20720707 is the required selection
• Both parts meet identical voltage, pitch, circuit count, and flammability specifications
• Bottom termination method (PC pin versus wire wrap) must be compatible with PCB design

Frequently Asked Questions (FAQ)

Q: Can 6WWV-07-008 replace CB20720707 in all applications?

A: No. The 6WWV-07-008 is rated for 25A maximum current, while the CB20720707 is rated for 30A. Substitution is valid only when the application current requirement does not exceed 25A. All other electrical and mechanical parameters are equivalent.

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

A: PC pin termination uses a single pin for PCB insertion, while wire wrap termination uses a wrapped wire connection. Both methods complete the circuit path. Selection depends on PCB design compatibility and assembly process requirements.

Q: Are the pitch and circuit spacing identical between these parts?

A: Yes. Both parts feature 0.375" (9.53mm) pitch spacing with 7 circuits in a single row configuration. Physical footprint and spacing are identical.

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

A: Yes. Both parts are rated UL94 V-0 for flammability and meet EAR99 export classification. CB20720707 is ROHS3 compliant while 6WWV-07-008 is RoHS compliant. Both meet HTSUS 8536.90.4000 classification.

Q: What is the operating temperature difference between these parts?

A: CB20720707 operates from -40°C to 105°C. The 6WWV-07-008 specification indicates 105°C maximum without a stated minimum. For applications requiring operation below 0°C, CB20720707 is the required selection.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Physical and electrical compatibility exists for applications within the 25A current limit. However, the different bottom termination methods (PC pin versus wire wrap) require PCB design verification. Consult PCB layout documentation to confirm termination method compatibility.

Q: What wire gauges are compatible with both parts?

A: Both parts accept 12-22 AWG wire gauge. Wire termination procedures and screw torque specifications should be verified in the respective manufacturer documentation.
