A201403RC Equivalent & Substitute Parts

Part Overview

The A201403RC is a 3-circuit barrier block connector manufactured by Eaton - Electronics Division, designed for chassis and panel mounting applications. This component features 0.375" (9.53mm) pitch spacing with screw-based top termination and solder turret bottom termination. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing maintenance, repair, and new design applications where this connector type remains suitable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the A201403RC is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Terminal Block Type: Barrier Block
• Number of Circuits: 3
• Pitch: 0.375" (9.53mm)
• Number of Rows: 1
• Wire Gauge Range: 12-22 AWG
• Top Termination: Screws
• Bottom Termination: Solder Turret, Insulated
• Barrier Type: 2 Wall (Dual)
• Mounting Type: Chassis, Panel
• Voltage Rating: 300V
• Material Flammability Rating: UL94 V-0

Allowable Parameter Variations:

• Current Rating: Substitute must meet or exceed 30A requirement
• Operating Temperature Range: Substitute must support minimum -40°C to 105°C
• Terminal Screw Material: Steel acceptable
• Insulation Material: Thermoplastic or equivalent polymeric materials
• Product Status: Active or Obsolete

The Curtis Industries T38320-03-0 meets all mandatory matching parameters and is therefore classified as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The T38320-03-0 from Curtis Industries is functionally equivalent to the A201403RC for applications where the 20A current rating is sufficient. The substitute part is currently in active production status with 758 units in stock, providing supply continuity for the obsolete A201403RC.

Key Considerations:

1. Current Rating Differential: The A201403RC is rated for 30A while the T38320-03-0 is rated for 20A. Circuit designs operating at currents between 20A and 30A require evaluation to confirm the substitute's adequacy.

2. Compliance Status: Both parts carry UL94 V-0 flammability certification and are classified under identical HTSUS code 8536.90.4000. The T38320-03-0 holds ROHS3 compliance and REACH Unaffected status.

3. Insulation Material: The substitute uses polypropylene (PP) insulation versus the original thermoplastic specification. Both materials satisfy UL94 V-0 requirements.

4. Operating Temperature: The original part specifies -40°C to 105°C operation. The substitute documentation provides only the upper limit of 105°C. Applications requiring confirmed low-temperature operation below 0°C should be evaluated against the substitute's actual performance envelope.

5. Packaging: The T38320-03-0 is supplied in bulk packaging, whereas the A201403RC packaging specification is not provided.

Frequently Asked Questions (FAQ)

Q: Can the T38320-03-0 directly replace the A201403RC in all applications?

A: Direct replacement is possible for applications where circuit current does not exceed 20A. The 10A current rating reduction must be evaluated against actual circuit requirements. All other electrical and mechanical parameters are compatible.

Q: What is the significance of the pitch specification in barrier block selection?

A: Pitch (0.375" in this case) determines the physical spacing between circuits and directly affects PCB layout, wire routing, and mounting hole positioning. Both the original and substitute parts share identical 0.375" pitch, ensuring mechanical interchangeability in existing designs.

Q: Are the solder turret terminations identical between these parts?

A: Both parts feature solder turret bottom termination with insulation. The termination style, geometry, and electrical characteristics are equivalent, supporting direct soldering into existing PCB designs.

Q: Does the polypropylene insulation in the substitute affect performance?

A: Polypropylene is a thermoplastic material meeting the same UL94 V-0 flammability standard as the original thermoplastic insulation. Both materials provide equivalent electrical isolation and thermal performance within the specified operating range.

Q: What is the impact of the 2 Wall (Dual) barrier configuration?

A: The dual-wall barrier design provides electrical isolation between adjacent circuits. Both parts incorporate this feature identically, maintaining the same level of circuit separation and safety.

Q: How does the screw termination compare between these parts?

A: Both parts use steel screws for top-side wire termination. The screw finish differs (zinc on original, nickel on substitute), but both finishes provide corrosion resistance suitable for the specified voltage and current ratings.

Q: Is the T38320-03-0 suitable for new designs?

A: Yes. The T38320-03-0 is in active production status with confirmed inventory availability. It meets all applicable compliance standards and can be specified for new designs where the 20A current rating satisfies circuit requirements.
