Key Parameters

Substitute Part Grouping Explanation

Substitution of the CB10210807 is based on the following critical parameters that must remain consistent:

• Number of Circuits and Pitch: Both the main part and substitute must maintain 8 circuits at 0.325" (8.26mm) pitch to ensure mechanical compatibility with existing PCB layouts and connector housings.
• Terminal Block Type and Barrier Configuration: The barrier block type with 3-wall (tri) barrier design must be preserved for electrical isolation and safety compliance.
• Termination Style: Both top (screws with captive plate) and bottom (PC pin) termination methods must match to ensure compatibility with existing wiring and PCB mounting infrastructure.
• Wire Gauge Compatibility: The 14-22 AWG wire gauge range must be supported by the substitute part.
• Mounting Type: Through-hole mounting must be maintained for PCB integration.
• Flammability and Insulation Material: UL94 V-0 rating and compatible insulation materials ensure safety and regulatory compliance.

The CB11210807 qualifies as a substitute based on these parameters. While the substitute part operates at a lower current rating (15A versus 20A) and higher voltage rating (300V versus 250V), it maintains all critical mechanical and electrical compatibility parameters required for direct substitution in applications within its current and voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

The CB11210807 is the active equivalent substitute for the obsolete CB10210807. Selection of the CB11210807 is appropriate for applications where the following conditions are met:

• Current Requirements: The application circuit operates at 15A or below. The CB10210807 supports 20A; therefore, applications requiring current levels between 15A and 20A cannot use the CB11210807 as a direct substitute.
• Voltage Requirements: The application operates at 250V or below. The CB11210807 supports 300V, providing additional voltage margin.
• Temperature Operating Range: The application operates within -40°C to 105°C. The CB11210807 extends the upper temperature limit to 120°C, providing additional thermal margin.
• Product Status and Availability: The CB11210807 is active and currently in stock (695 pcs), whereas the CB10210807 is obsolete. For new designs or long-term procurement, the CB11210807 is the appropriate selection.
• Regulatory Compliance: Both parts maintain UL94 V-0 flammability rating and equivalent electrical isolation characteristics through identical barrier block design.

Frequently Asked Questions (FAQ)

Q: Can the CB11210807 be used as a direct replacement for the CB10210807 in all applications?

A: The CB11210807 is mechanically and electrically compatible with the CB10210807 for applications operating at 15A or below and 250V or below. Applications requiring the full 20A current rating of the CB10210807 cannot use the CB11210807 as a substitute.

Q: What are the key mechanical compatibility factors between these parts?

A: Both parts maintain identical mechanical compatibility through matching circuit count (8), pitch (0.325"), termination style (screws with captive plate on top, PC pin on bottom), barrier configuration (3-wall tri-barrier), and through-hole mounting. PCB layouts and connector housings designed for the CB10210807 accommodate the CB11210807 without modification.

Q: How do the electrical ratings differ between the main part and substitute?

A: The CB10210807 is rated for 20A at 250V. The CB11210807 is rated for 15A at 300V. The substitute provides higher voltage capability but lower current capacity. Circuit design must operate within the 15A current limit of the substitute.

Q: Are there differences in insulation material between these parts?

A: The CB10210807 uses thermoplastic insulation, while the CB11210807 uses polyamide (PA66) nylon 6/6. Both materials achieve UL94 V-0 flammability rating and maintain equivalent electrical isolation and safety characteristics.

Q: What is the temperature operating range difference?

A: The CB10210807 operates from -40°C to 105°C. The CB11210807 extends the upper limit to 120°C. For applications operating above 105°C, the CB11210807 provides additional thermal margin.

Q: Is the CB11210807 available for procurement?

A: Yes. The CB11210807 is active product status with 695 pieces in stock, whereas the CB10210807 is obsolete. The CB11210807 is the recommended selection for new procurement and long-term system support.

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

A: Yes. Both the CB10210807 and CB11210807 maintain UL94 V-0 flammability rating and equivalent electrical isolation through identical 3-wall tri-barrier block design.
