Key Parameters

Substitute Part Grouping Explanation

Substitution of the A20140807RC is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Terminal block type: Barrier Block
• Number of circuits: 8
• Pitch spacing: 0.375" (9.53mm)
• Number of rows: 1
• Top termination method: Screws with Captive Plate
• Bottom termination method: Solder Turret, Insulated
• Barrier configuration: 2 Wall (Dual)
• Voltage rating: 300V minimum
• Wire gauge compatibility: 12-22 AWG
• Mounting configuration: Chassis, Panel

The Curtis Industries T38328-08-0 satisfies all mandatory matching parameters. Variations in current rating, insulation material composition, and compliance certifications do not preclude substitution when electrical and mechanical interface requirements are met.

Parameter Comparison

Engineering Selection Recommendations

The T38328-08-0 from Curtis Industries is a direct functional equivalent to the A20140807RC. Both components share identical mechanical interfaces, electrical termination methods, and circuit configurations.

Product Status Consideration: The A20140807RC is obsolete, while the T38328-08-0 is active production. Selection of the active component ensures continued availability for future procurement and maintenance requirements.

Compliance Consideration: The T38328-08-0 is ROHS3 compliant, whereas the A20140807RC is non-compliant. Applications subject to RoHS regulations require the Curtis Industries substitute.

Current Rating Differential: The A20140807RC is rated for 30A continuous current, while the T38328-08-0 is rated for 20A. Circuit designs operating at currents between 20A and 30A require verification that the 20A rating of the substitute is acceptable for the specific application.

Temperature Range: The A20140807RC specifies -40°C minimum operating temperature; the T38328-08-0 specification does not include a minimum temperature. Applications requiring operation below 0°C require confirmation of the substitute's low-temperature performance.

Frequently Asked Questions (FAQ)

Q: Can the T38328-08-0 be used as a direct replacement for the A20140807RC in existing circuit board designs?

A: Yes, provided that the circuit current does not exceed 20A continuous. The mechanical footprint, pitch spacing (0.375"), solder turret configuration, and screw termination are identical. PCB layout modifications are not required.

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

A: The current rating represents the maximum continuous current the terminal block can safely conduct without exceeding temperature limits. If the original circuit design operates at currents between 20A and 30A, the substitute may not be suitable without circuit redesign or thermal analysis.

Q: Are there compatibility issues with the different insulation materials (Thermoplastic vs. Polypropylene)?

A: Both materials achieve UL94 V-0 flammability rating and are suitable for 300V applications. The polypropylene insulation in the T38328-08-0 provides equivalent electrical and thermal performance for standard industrial applications.

Q: Does the RoHS3 compliance of the T38328-08-0 affect compatibility with non-RoHS systems?

A: No. RoHS3 compliance indicates the absence of restricted substances. A RoHS-compliant component functions identically in non-RoHS systems. Conversely, a non-compliant component cannot be used in RoHS-regulated applications.

Q: What is the minimum operating temperature for the T38328-08-0?

A: The provided specifications do not include a minimum operating temperature for the T38328-08-0. Applications requiring operation below 0°C should confirm the low-temperature performance with Curtis Industries technical documentation.

Q: Are the packaging formats compatible?

A: The A20140807RC is packaged as individual units; the T38328-08-0 is supplied in bulk packaging. This affects procurement and inventory management but does not impact functional compatibility.
