Eaton A202230 Equivalent & Substitute Parts

Part Overview

The Eaton A202230 is a 30-circuit barrier block connector with 0.375" (9.53mm) pitch, designed for through-hole mounting applications requiring 30A current capacity at 300V. This component features dual-wall barrier construction with screw termination on the top and PC pin termination on the bottom, accommodating 12-22 AWG wire gauges across an operating temperature range of -40°C to 105°C.

The A202230 carries an obsolete product status. Locating equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for legacy systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Eaton A202230 is determined by the following critical parameters:

Primary Matching Criteria:

• Terminal block type: Barrier block construction
• Circuit count: 30 circuits
• Pitch tolerance: 0.375" ± 0.001" (9.53mm ± 0.025mm)
• Termination configuration: Screw top termination with PC pin bottom termination
• Barrier construction: Dual-wall (2 Wall) barrier type
• Mounting interface: Through-hole PCB mounting
• Wire gauge compatibility: 12-22 AWG acceptance range

Secondary Compatibility Parameters:

• Voltage rating: Minimum 300V
• Current rating: Minimum 30A
• Operating temperature range: Minimum -40°C to 105°C
• Flammability rating: UL94 V-0 or equivalent
• Insulation material: Thermoplastic

The Amphenol Anytek YK5013003000G qualifies as a substitute based on matching circuit count, pitch specification (0.374" vs. 0.375" represents a 0.001" tolerance variance within acceptable mechanical limits), dual-wall barrier type, screw termination with PC pin configuration, through-hole mounting, wire gauge range, voltage rating, and flammability certification.

Parameter Comparison

Engineering Selection Recommendations

Current Rating Consideration: The Amphenol Anytek YK5013003000G carries a 20A current rating compared to the Eaton A202230's 30A rating. Applications operating at or near 30A continuous current require verification that the substitute's 20A rating satisfies the actual circuit requirements. If the application operates below 20A, the substitute is suitable. If sustained operation at 25-30A is required, the current rating differential presents a material incompatibility.

Compliance and Supply Status: The YK5013003000G maintains active product status with ROHS3 compliance, addressing the obsolescence and environmental regulation limitations of the original A202230. The extended operating temperature range (-40°C to 115°C versus -40°C to 105°C) provides additional thermal margin for applications in elevated ambient conditions.

Mechanical Interface: The pitch variance of 0.001" (0.374" versus 0.375") falls within standard PCB manufacturing tolerances and does not present a mechanical incompatibility for through-hole mounting. The captive plate feature on the substitute's screw termination provides enhanced wire retention without compromising functional compatibility.

Regulatory Alignment: Both components maintain UL94 V-0 flammability certification and identical voltage/wire gauge specifications. The substitute's ROHS3 compliance supports integration into modern supply chains and regulatory environments where non-compliant components present procurement restrictions.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol Anytek YK5013003000G directly replace the Eaton A202230 in existing PCB designs?

A: Direct replacement is mechanically feasible due to identical circuit count, termination configuration, and through-hole mounting interface. The 0.001" pitch variance is within PCB manufacturing tolerance. However, the 20A current rating of the substitute versus the 30A rating of the original requires verification that the application's actual current draw does not exceed 20A continuous.

Q: What is the significance of the captive plate feature on the YK5013003000G?

A: The captive plate on the screw termination provides mechanical retention of the wire during insertion and removal operations. This feature enhances assembly reliability and reduces the risk of wire displacement during maintenance. It does not affect electrical performance or compatibility with standard wire gauges.

Q: Does the 0.001" pitch difference affect PCB layout compatibility?

A: No. The 0.001" (0.025mm) difference between 0.375" and 0.374" pitch falls within standard PCB manufacturing tolerances of ±0.005" for through-hole component spacing. PCB designs accommodating the original A202230 will accept the YK5013003000G without layout modification.

Q: Why is the current rating lower on the substitute part?

A: The YK5013003000G is rated for 20A continuous current, while the A202230 is rated for 30A. This difference reflects the thermal and contact design specifications of each manufacturer's connector architecture. Applications must operate within the substitute's 20A rating to ensure reliable long-term performance.

Q: Is the extended operating temperature range of the YK5013003000G (-40°C to 115°C) a functional advantage?

A: The extended upper temperature limit of 115°C versus 105°C provides additional thermal margin for applications in elevated ambient environments or high-dissipation circuits. For applications operating within the original -40°C to 105°C range, both components perform identically.

Q: What is the impact of the ROHS3 compliance difference?

A: The YK5013003000G's ROHS3 compliance eliminates restrictions on lead content and hazardous substances, enabling integration into modern supply chains and compliance with current environmental regulations. The non-compliant A202230 may face procurement restrictions in regulated industries or regions with strict environmental standards.

Q: Are there any wire gauge or termination compatibility issues?

A: No. Both components accept 12-22 AWG wire and feature identical screw-to-PC pin termination configuration. The captive plate on the substitute does not restrict wire insertion or removal procedures.
