CB20222807 Equivalent & Substitute Parts

Part Overview

The CB20222807 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 accommodates wire gauges from 12-22 AWG with a 30A current rating at 300V. The connector utilizes screws with a captive plate for top termination and PC pins for bottom termination, with a tri-wall barrier design for circuit isolation.

The CB20222807 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.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CB20222807 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Terminal block type (Barrier Block)
• Number of circuits (28)
• Pitch specification (0.375" ± tolerance)
• Current rating (30A minimum)
• Voltage rating (300V minimum)
• Wire gauge compatibility (12-22 AWG minimum range)
• Top termination method (Screws with Captive Plate)
• Bottom termination method (PC Pin)
• Barrier configuration (3 Wall Tri-design)
• Mounting configuration (Through Hole)
• Flammability rating (UL94 V-0)

The substitute part YK4412803000G from Amphenol Anytek meets these criteria with a pitch of 0.374" (9.50mm), which represents a 0.03mm variance from the original specification. This minimal pitch deviation falls within standard manufacturing tolerances for barrier block connectors and maintains mechanical and electrical compatibility. The substitute part supports an expanded wire gauge range (10-22 AWG) and operates across a wider temperature range (-40°C to 115°C versus -40°C to 105°C), providing enhanced performance characteristics.

Engineering Selection Recommendations

Primary Substitute: YK4412803000G

The YK4412803000G from Amphenol Anytek is the qualified substitute for the obsolete CB20222807. This selection is based on the following engineering factors:

Product Status Alignment: The YK4412803000G maintains active production status, ensuring long-term component availability and supply chain continuity. The CB20222807's obsolete classification creates sourcing risk; the substitute addresses this through an established, current product line.

Compliance and Certification: Both parts maintain UL94 V-0 flammability certification, confirming equivalent safety performance. The YK4412803000G achieves ROHS3 compliance, whereas the CB20222807 is non-compliant. For applications subject to RoHS regulations, the substitute provides regulatory alignment. The YK4412803000G carries REACH Unaffected status, indicating no restricted substances of concern.

Electrical and Mechanical Equivalence: The substitute maintains identical current (30A) and voltage (300V) ratings, wire entry configuration (28 circuits), termination methods (screws with captive plate and PC pins), and barrier design (3-wall tri-configuration). The pitch variance of 0.03mm (0.374" versus 0.375") is within standard manufacturing tolerances for barrier block connectors and does not affect mechanical or electrical compatibility.

Enhanced Performance Characteristics: The YK4412803000G supports an expanded operating temperature range (-40°C to 115°C versus -40°C to 105°C) and accommodates a broader wire gauge range (10-22 AWG versus 12-22 AWG), providing design flexibility for applications with varying thermal or conductor requirements.

Frequently Asked Questions (FAQ)

Q: What is the primary reason the CB20222807 requires a substitute?

A: The CB20222807 is classified as obsolete, meaning it is no longer in active production. The YK4412803000G substitute ensures continued component availability and supply chain reliability for systems utilizing this connector type.

Q: Is the pitch difference between CB20222807 (0.375") and YK4412803000G (0.374") significant?

A: No. The 0.03mm pitch variance falls within standard manufacturing tolerances for barrier block connectors. This difference does not affect mechanical fit, electrical performance, or circuit isolation characteristics. Both parts maintain identical circuit spacing functionality.

Q: Can the YK4412803000G be used in applications originally designed for the CB20222807?

A: Yes. The YK4412803000G meets all critical electrical and mechanical parameters: 28 circuits, 30A current rating, 300V voltage rating, identical termination methods, and tri-wall barrier design. The substitute is mechanically and electrically compatible with existing PCB layouts and connector housings designed for the CB20222807.

Q: What is the advantage of the YK4412803000G's expanded wire gauge range (10-22 AWG)?

A: The broader wire gauge range provides design flexibility. Applications using conductors smaller than 12 AWG can utilize the substitute without modification, whereas the original part restricts wire selection to 12-22 AWG. This expanded range does not compromise compatibility with the original 12-22 AWG specification.

Q: Does the YK4412803000G's higher operating temperature range affect compatibility?

A: No. The YK4412803000G operates from -40°C to 115°C, compared to the CB20222807's -40°C to 105°C range. This extended upper temperature limit represents enhanced performance and does not create incompatibility. Applications operating within the original temperature range remain fully compatible.

Q: What is the significance of the YK4412803000G's ROHS3 compliance?

A: ROHS3 compliance indicates the substitute meets current European Union Restriction of Hazardous Substances regulations. For applications subject to RoHS requirements, the YK4412803000G provides regulatory alignment, whereas the CB20222807 does not. For applications without RoHS requirements, this difference does not affect functional compatibility.

Q: Are there any packaging differences between the CB20222807 and YK4412803000G?

A: The CB20222807 is packaged in standard format, while the YK4412803000G is supplied in bulk packaging. Both configurations contain identical connector components. Bulk packaging may affect order quantities and handling procedures but does not alter the connector's electrical or mechanical specifications.

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

A: Yes. Both connectors feature identical through-hole mounting configurations, PC pin bottom termination, and mechanical dimensions within manufacturing tolerances. The YK4412803000G can be substituted directly into existing designs without PCB layout modifications.
