A20140307RC Equivalent & Substitute Parts

Part Overview

The A20140307RC is a 3-circuit barrier block connector manufactured by Eaton - Electronics Division, part of the A2000 series. This component features a 0.375" (9.53mm) pitch configuration with screw termination and captive plate design for top connection and solder turret insulated termination for bottom connection. The product is classified as obsolete, necessitating identification of equivalent substitute components for ongoing applications and new designs requiring compatible barrier block connectors with matching electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute relationships for the A20140307RC are established based on strict equivalence of core electrical and mechanical parameters. The following criteria determine substitution eligibility:

Primary Matching Parameters:

• Terminal block type: Barrier Block
• Number of circuits: 3
• Pitch: 0.375" (9.53mm)
• Number of rows: 1
• Voltage rating: 300V
• Wire gauge range: 12-22 AWG
• Top termination: Screws with Captive Plate
• Bottom termination: Solder Turret, Insulated
• Barrier type: 2 Wall (Dual)
• Mounting type: Chassis, Panel
• Flammability rating: UL94 V-0

The Curtis Industries T38328-03-0 satisfies all primary matching parameters and is therefore classified as an equivalent substitute. Variations in current rating, insulation material composition, and compliance status are secondary parameters that do not preclude substitution when electrical and mechanical form factors are identical.

Parameter Comparison

Engineering Selection Recommendations

The T38328-03-0 from Curtis Industries serves as the primary equivalent substitute for the obsolete A20140307RC. Both components share identical electrical and mechanical specifications across all critical parameters: 3-circuit configuration, 0.375" pitch, 300V voltage rating, 12-22 AWG wire gauge compatibility, dual-wall barrier design, and UL94 V-0 flammability rating.

The T38328-03-0 is currently in active production status with 1044 units available in inventory, providing supply continuity for applications previously utilizing the A20140307RC. The substitute component maintains full mechanical and electrical compatibility for chassis and panel mounting applications.

Secondary parameter differences exist in current rating (T38328-03-0 rated at 20A versus A20140307RC at 30A) and insulation material composition (polypropylene versus thermoplastic). The T38328-03-0 achieves ROHS3 compliance status, whereas the original component is RoHS non-compliant. These differences do not affect form-factor compatibility or core electrical performance within the specified 300V, 12-22 AWG operating envelope.

Frequently Asked Questions (FAQ)

Q: Can the T38328-03-0 be used as a direct replacement for the A20140307RC in existing designs?

A: Yes. The T38328-03-0 matches all primary electrical and mechanical parameters: 3 circuits, 0.375" pitch, 300V rating, 12-22 AWG wire gauge, dual-wall barrier configuration, and identical termination methods. Physical form factor and mounting compatibility are equivalent.

Q: What is the significance of the current rating difference (30A versus 20A)?

A: The A20140307RC is rated for 30A maximum current, while the T38328-03-0 is rated for 20A. Applications requiring current levels between 20A and 30A must evaluate whether the lower rating of the substitute component is acceptable for the specific circuit design.

Q: Does the insulation material change from thermoplastic to polypropylene affect performance?

A: Both materials achieve UL94 V-0 flammability rating and operate across the specified temperature range. The material change does not affect electrical performance, voltage rating, or mechanical compatibility within the defined operating parameters.

Q: What is the impact of RoHS compliance differences?

A: The T38328-03-0 is ROHS3 compliant, while the A20140307RC is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the T38328-03-0 provides compliance status. For legacy systems without RoHS mandates, this difference is not functionally relevant.

Q: Are there packaging considerations when sourcing the T38328-03-0?

A: The T38328-03-0 is supplied in bulk packaging, whereas the A20140307RC packaging specification is not provided. Bulk packaging is standard for barrier block connectors and does not affect component functionality or installation.

Q: What is the operating temperature range for the substitute component?

A: The T38328-03-0 operates at 105°C maximum, while the A20140307RC operates across -40°C to 105°C. The substitute component specification does not explicitly state the minimum operating temperature; applications requiring operation below 0°C should confirm temperature range compatibility with the manufacturer.
