Key Parameters

Substitute Part Grouping Explanation

Substitution of the CB20222807EB is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of circuits: 28
• Terminal block type: Barrier block
• Top termination method: Screws with captive plate
• Bottom termination method: PC pin
• Barrier configuration: 3 Wall (Tri)
• Current rating: 30A minimum
• Voltage rating: 300V minimum
• Mounting type: Through hole compatibility

Allowable Variation Parameters:

• Pitch tolerance: 0.375" ± 0.001" (9.53mm ± 0.025mm)
• Wire gauge range: Minimum 10 AWG acceptable (CB20222807EB specifies 12-22 AWG)
• Operating temperature: Higher maximum rating acceptable
• Product status: Active status preferred for ongoing availability
• Compliance certifications: Enhanced compliance (RoHS3, REACH) acceptable

The YK4422803000G meets all mandatory matching criteria and represents a direct functional equivalent with enhanced specifications in temperature range and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement Applications:

The YK4422803000G from Amphenol Anytek serves as a functional equivalent for the obsolete CB20222807EB. Both components share identical circuit count, electrical ratings, termination methods, and barrier configuration. The pitch differential of 0.001" (0.03mm) falls within standard manufacturing tolerances for barrier block connectors and does not affect PCB footprint compatibility or mechanical fit.

Compliance Advantages:

The YK4422803000G provides enhanced regulatory compliance through ROHS3 certification and REACH unaffected status, addressing modern supply chain and environmental requirements. The extended operating temperature range (-40°C to 115°C versus -40°C to 105°C) provides additional thermal margin for demanding applications.

Availability Consideration:

The CB20222807EB is classified as obsolete with limited inventory (1088 pieces). The YK4422803000G maintains active production status with current inventory availability (820 pieces), ensuring long-term supply chain continuity for new designs and ongoing maintenance requirements.

Mechanical Compatibility:

The YK4422803000G supports both through-hole and right-angle mounting configurations, providing installation flexibility beyond the original part specification. This enhanced capability does not compromise direct replacement functionality in standard through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can the YK4422803000G replace the CB20222807EB in existing assemblies?

A: Yes. Both components are 28-circuit barrier blocks with identical electrical ratings (30A, 300V), matching termination methods (screws with captive plate top, PC pin bottom), and 3-wall barrier configuration. The pitch difference of 0.001" is within standard manufacturing tolerance and does not affect PCB compatibility.

Q: What is the significance of the pitch difference (0.375" vs 0.374")?

A: The 0.001" (0.03mm) difference represents standard manufacturing tolerance for barrier block connectors. This variation does not affect PCB footprint compatibility, component spacing, or electrical performance. Both parts are mechanically and electrically interchangeable in circuit applications.

Q: Does the YK4422803000G support the same wire gauge range?

A: The YK4422803000G supports 10-22 AWG, which encompasses the CB20222807EB specification of 12-22 AWG. The extended lower range provides additional flexibility for applications requiring smaller gauge conductors.

Q: What are the compliance differences between these parts?

A: The CB20222807EB is RoHS non-compliant, while the YK4422803000G is ROHS3 compliant and REACH unaffected. Both maintain UL94 V-0 flammability certification. The YK4422803000G meets current environmental and regulatory standards required for modern supply chains.

Q: Is the extended temperature range of the YK4422803000G significant?

A: The YK4422803000G operates to 115°C versus 105°C for the CB20222807EB. This 10°C additional margin provides enhanced thermal performance in high-temperature environments without affecting standard operating conditions.

Q: Can the YK4422803000G be used in right-angle mounting applications?

A: Yes. The YK4422803000G supports both through-hole and right-angle mounting configurations. The CB20222807EB supports through-hole mounting only. This additional capability in the substitute part does not affect standard through-hole replacement applications.

Q: What is the inventory status for each part?

A: The CB20222807EB (obsolete) has 1088 pieces in stock. The YK4422803000G (active production) has 820 pieces in stock. For new designs and long-term applications, the YK4422803000G is recommended due to active production status and ongoing availability.

Q: Are there any packaging differences?

A: The CB20222807EB packaging is listed as unspecified. The YK4422803000G is supplied in bulk packaging. Confirm packaging requirements with your procurement department for specific application needs.
