CB20722807EB Equivalent & Substitute Parts Reference

Part Overview

The CB20722807EB is a 28-circuit barrier block connector manufactured by Eaton - Electronics Division, part of the Magnum® CB2000 series. This through-hole mounted terminal block features a 0.375" (9.53mm) pitch and is rated for 30A at 300V with wire gauges from 12-22 AWG. The component utilizes screws with captive plate termination on the top and PC pin termination on the bottom, with a tri-wall (3 Wall) barrier configuration.

The CB20722807EB is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production or repair requirements for systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CB20722807EB is evaluated based on the following critical parameters that define functional and mechanical compatibility:

Core Compatibility Criteria:

• Terminal block type (Barrier Block)
• Number of circuits (28)
• Pitch tolerance (0.375" nominal)
• Current and voltage ratings (30A, 300V minimum)
• Wire gauge accommodation (minimum 12-22 AWG range)
• Top termination method (Screws with Captive Plate)
• Barrier configuration (3 Wall tri-wall design)
• Flammability rating (UL94 V-0)
• Through-hole mounting capability

The substitute part YK4462803000G from Amphenol Anytek meets these core criteria with minor variations in pitch tolerance (0.374" vs. 0.375"), wire gauge range expansion (10-22 AWG vs. 12-22 AWG), and bottom termination method (Wire Wrap vs. PC Pin). These variations remain within acceptable substitution parameters for barrier block connectors in this category.

Parameter Comparison

Engineering Selection Recommendations

CB20722807EB (Eaton - Obsolete): The original part is classified as obsolete and carries RoHS non-compliant status. While 753 units remain in stock, this part number is no longer in active production. Selection of this part is limited to existing inventory applications or legacy system maintenance where exact part matching is mandatory.

YK4462803000G (Amphenol Anytek - Active): This substitute part is currently in active production status with ROHS3 compliance certification, making it suitable for new designs and ongoing procurement. The part maintains electrical equivalence (30A, 300V, UL94 V-0) and mechanical compatibility (28-circuit barrier block, tri-wall configuration, through-hole mounting). The extended operating temperature range (-40°C ~ 115°C vs. -40°C ~ 105°C) provides additional thermal margin. Inventory availability is higher at 894 units.

The pitch tolerance difference (0.374" vs. 0.375") represents a 0.03mm variation, which is within standard PCB layout tolerances for through-hole connectors. The wire gauge range expansion (10-22 AWG vs. 12-22 AWG) provides additional flexibility for smaller gauge wire applications.

Frequently Asked Questions (FAQ)

Q: Can YK4462803000G directly replace CB20722807EB in existing PCB designs?

A: The pitch tolerance difference of 0.03mm (0.374" vs. 0.375") is within standard through-hole connector tolerances. PCB hole spacing designed for 0.375" pitch will accommodate the 0.374" pitch connector. Physical mounting and electrical function remain compatible.

Q: What is the significance of the bottom termination difference (PC Pin vs. Wire Wrap)?

A: The CB20722807EB uses PC pin termination for direct PCB soldering. The YK4462803000G uses wire wrap termination, which requires wire wrap tooling for connection to PCB traces or backplane wiring. This difference affects assembly methodology but does not impact electrical performance or current/voltage ratings.

Q: Does the extended operating temperature range of YK4462803000G affect compatibility?

A: The YK4462803000G operates from -40°C to 115°C compared to -40°C to 105°C for the CB20722807EB. This extended range is a superset of the original specification and provides additional thermal margin. No compatibility issues arise from this difference.

Q: Is RoHS compliance a factor in substitution decisions?

A: The CB20722807EB is RoHS non-compliant while YK4462803000G is ROHS3 compliant. For new designs or applications subject to RoHS regulations, the YK4462803000G is the appropriate selection. For legacy system maintenance using existing CB20722807EB inventory, RoHS status does not affect functional compatibility.

Q: Are there wire gauge limitations when substituting?

A: The CB20722807EB accommodates 12-22 AWG wire. The YK4462803000G accommodates 10-22 AWG wire, providing expanded capability for smaller gauge applications. Both parts support the full 12-22 AWG range, ensuring compatibility for standard wire gauge selections.

Q: What packaging considerations apply to these parts?

A: The CB20722807EB is supplied in unspecified packaging with 753 units in stock. The YK4462803000G is supplied in bulk packaging with 894 units in stock. Both are through-hole mounted components suitable for manual or automated assembly processes.
