CFTD-2 Equivalent & Substitute Parts

Part Overview

The CFTD-2 is a 2-circuit barrier block connector manufactured by Curtis Industries, designed for chassis and panel mounting applications. This component features a 0.375" (9.53mm) pitch with screw termination on the top and PC pin termination on the bottom. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CFTD-2 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Circuits: 2
• Pitch: 0.375" (9.53mm)
• Terminal Block Type: Barrier Block
• Barrier Type: 2 Wall (Dual)
• Voltage Rating: 300V
• Wire Gauge: 12-22 AWG
• Mounting Type: Chassis, Panel
• Flammability Rating: UL94 V-0

Allowable Variations:

• Current Rating: Substitute must meet or exceed 20A
• Operating Temperature: Substitute must support minimum 140°C
• Top Termination: Screws or Screws with Captive Plate
• Bottom Termination: PC Pin (insulated or non-insulated)
• Insulation Material: Polyester Thermoplastic or Polybutylene Terephthalate (PBT)
• RoHS Compliance: RoHS Compliant or ROHS3 Compliant

The Molex 0387207402 meets all mandatory matching parameters and allowable variation criteria, qualifying it as a direct functional substitute.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0387207402 is the qualified substitute for the obsolete CFTD-2. Both components share identical electrical specifications (300V, 20A/25A, 12-22 AWG), mechanical configuration (2-circuit, 0.375" pitch, dual-wall barrier), and safety certifications (UL94 V-0). The Molex part exceeds the current rating requirement (25A vs. 20A) and maintains full RoHS compliance under the ROHS3 standard.

The primary design difference is the operating temperature range. The CFTD-2 supports continuous operation to 140°C, while the Molex 0387207402 is rated to 100°C maximum. Applications requiring sustained operation above 100°C require thermal analysis to confirm compatibility. The Molex part also features a captive plate on the screw termination, which provides additional mechanical retention compared to standard screws.

Both components are suitable for chassis and panel mounting with identical pitch and flange configuration, ensuring mechanical interchangeability in standard mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0387207402 directly replace the CFTD-2 in all applications?

A: The Molex 0387207402 is mechanically and electrically compatible for applications operating at or below 100°C. Applications requiring sustained operation above 100°C must be evaluated separately, as the CFTD-2 supports 140°C operation while the Molex part is limited to 100°C maximum.

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

A: The captive plate on the Molex 0387207402 screw termination provides positive retention of the screw, preventing accidental loosening during vibration or thermal cycling. This is an enhancement over the standard screw termination of the CFTD-2 and does not affect electrical or mechanical compatibility.

Q: Are there packaging differences between the CFTD-2 and the Molex 0387207402?

A: The CFTD-2 is supplied without specified packaging, while the Molex 0387207402 is packaged in trays. This difference affects handling and storage but does not impact component performance or compatibility.

Q: Do both parts meet current environmental compliance standards?

A: Yes. The CFTD-2 is RoHS Compliant, and the Molex 0387207402 is ROHS3 Compliant. Both meet current regulatory requirements for hazardous substance restrictions.

Q: What is the pitch specification and why is it critical for substitution?

A: Both components feature a 0.375" (9.53mm) pitch, which defines the center-to-center spacing between circuits. Pitch is a critical substitution parameter because it determines mechanical fit on printed circuit boards and in mounting assemblies. Pitch mismatch prevents proper installation.

Q: Can the insulation material difference affect performance?

A: Both Polyester Thermoplastic (CFTD-2) and Polybutylene Terephthalate (PBT, Molex 0387207402) achieve UL94 V-0 flammability rating and are suitable for barrier block applications. The material difference does not affect electrical performance or safety certification in this application.
