Eaton A201303 Barrier Block Terminal Strip - Equivalent & Substitute Parts

Part Overview

The Eaton A201303 is a 3-circuit barrier block connector with 0.375" (9.53mm) pitch spacing, designed for chassis and panel mounting applications. This component features screw-type top termination and solder turret bottom termination, rated for 30A at 300V with wire gauge compatibility of 12-22 AWG. The A201303 is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Eaton A201303 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Terminal block type: Barrier Block
• Number of circuits: 3
• Pitch spacing: 0.375" (9.53mm)
• Wire gauge range: 12-22 AWG
• Top termination method: Screws
• Bottom termination method: Solder Turret, Insulated
• Barrier configuration: 2 Wall (Dual)
• Mounting capability: Chassis, Panel
• Flammability rating: UL94 V-0
• RoHS compliance: ROHS3 Compliant

Allowable Parameter Variations:

• Current rating: Substitute may be lower than 30A if application requirements permit
• Operating temperature range: Substitute may have different upper limit if minimum -40°C is maintained
• Voltage rating: Must meet or exceed 300V
• Product status: Active substitutes are preferred for obsolete parts

The TE Connectivity JC6-T307-03 meets all mandatory matching parameters and qualifies as a direct substitute.

Engineering Selection Recommendations

Eaton A201303 Substitution with TE Connectivity JC6-T307-03:

The TE Connectivity JC6-T307-03 is a qualified substitute for the obsolete Eaton A201303. Both components share identical mechanical and electrical specifications across all critical parameters: 3-circuit configuration, 0.375" pitch, screw top termination, solder turret bottom termination, dual-wall barrier design, and UL94 V-0 flammability rating.

The primary difference is current rating: the JC6-T307-03 is rated for 20A versus the A201303's 30A. This substitution is valid only when application current requirements do not exceed 20A. If the application requires the full 30A capacity of the original part, the JC6-T307-03 is not suitable.

Both parts maintain ROHS3 compliance and identical voltage rating of 300V. The JC6-T307-03 carries active product status, ensuring ongoing availability and supply chain continuity. The terminal screw finish on the JC6-T307-03 includes clear chromate plating in addition to zinc, providing enhanced corrosion resistance compared to the original part.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity JC6-T307-03 directly replace the Eaton A201303 in all applications?

A: Direct replacement is valid only when application current requirements do not exceed 20A. The JC6-T307-03 is rated for 20A maximum, while the A201303 is rated for 30A. If your circuit operates at currents between 20A and 30A, the JC6-T307-03 is not suitable.

Q: Are the physical dimensions and mounting footprints identical?

A: Yes. Both parts feature identical 0.375" (9.53mm) pitch spacing, single-row configuration, 3-circuit layout, and chassis/panel mounting capability. The flange design is identical on both components.

Q: What is the significance of the terminal screw finish difference?

A: The JC6-T307-03 includes clear chromate plating on the zinc finish, providing additional corrosion protection. This is a material enhancement and does not affect electrical or mechanical compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both the Eaton A201303 and TE Connectivity JC6-T307-03 are ROHS3 compliant and carry identical ECCN and HTSUS classifications.

Q: What wire gauge range is supported by the substitute part?

A: Both parts support 12-22 AWG wire gauge, with identical termination methods (screw top, solder turret bottom).

Q: Is the operating temperature range identical?

A: The A201303 specifies -40°C to 105°C. The JC6-T307-03 specifies 105°C maximum. If your application requires operation below 0°C, verify that the JC6-T307-03 meets your minimum temperature requirement.
