Cinch Connectivity Solutions 16-141 Barrier Block Terminal Connector

Part Overview

The Cinch Connectivity Solutions 16-141 is a 16-circuit barrier block terminal connector with 0.438" (11.12mm) pitch spacing, designed for industrial and panel-mount applications requiring secure screw-based termination. This connector accommodates 14 AWG wire gauge with a 20A current rating at 250V, featuring dual-wall barrier construction and phenolic insulation. The part is currently active in production with 800 units in stock. Equivalent substitute parts may be required due to supply chain constraints, application-specific compliance requirements, or design standardization across manufacturing facilities.

Key Parameters

Substitute Part Grouping Explanation

The Molex 0387800116 (Beau 38780 series) qualifies as a functional equivalent based on the following critical substitution parameters:

Matching Parameters:

• Terminal block type: Barrier block
• Number of circuits: 16
• Pitch spacing: 0.438" (11.12mm)
• Number of rows: 2
• Number of wire entries: 32
• Top termination method: Screws
• Bottom termination: Closed
• Barrier construction: 2 Wall (Dual)
• Flange feature: Present
• Color: Black
• Mounting type: Chassis, Panel
• ECCN classification: EAR99
• HTSUS code: 8536.90.4000

Allowable Parameter Variations:

• Current rating: 15A (substitute) vs. 20A (main part) — substitute operates within acceptable amperage range for equivalent circuit density
• Voltage rating: 300V (substitute) vs. 250V (main part) — substitute exceeds voltage requirement
• Wire gauge: 14-22 AWG (substitute) vs. 14 AWG (main part) — substitute accommodates broader wire range including main part specification
• Insulation material: Thermoplastic (substitute) vs. Phenolic (main part) — both materials meet barrier block performance standards
• Terminal screw finish: Zinc, Clear Chromate (substitute) vs. Nickel (main part) — both finishes provide corrosion resistance
• Compliance: ROHS3 Compliant (substitute) vs. RoHS Compliant (main part) — both meet regulatory requirements

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (Cinch 16-141): Use the Cinch 16-141 when the application requires the specified 20A current rating at 250V with phenolic insulation and nickel-plated terminals. This part is active in production with established supply availability.

Substitute Part Selection (Molex 0387800116): The Molex 0387800116 is suitable as a direct substitute when:

• The application circuit load does not exceed 15A per terminal
• Operating voltage does not exceed 300V
• Wire gauge requirements fall within the 14-22 AWG range
• Thermoplastic insulation meets environmental and flammability requirements
• Zinc chromate terminal finish is acceptable for the operating environment

Both parts carry current compliance certifications (RoHS/ROHS3) and share identical mechanical footprints, pitch spacing, and mounting configurations, enabling direct substitution in chassis and panel-mount applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0387800116 replace the Cinch 16-141 in all applications?

A: The Molex substitute is functionally equivalent for applications operating at or below 15A per terminal and 300V maximum. If your application requires the full 20A rating of the Cinch part, the substitute is not appropriate. Verify your circuit current requirements before substitution.

Q: What is the difference between phenolic and thermoplastic insulation in barrier blocks?

A: Both materials provide electrical insulation and mechanical support in barrier block construction. Phenolic (Cinch 16-141) offers higher temperature stability and rigidity. Thermoplastic (Molex 0387800116) provides flexibility and impact resistance. Selection depends on operating temperature range and environmental exposure requirements.

Q: Are the terminal screw finishes interchangeable?

A: Both nickel (Cinch) and zinc chromate (Molex) finishes provide corrosion resistance suitable for industrial applications. Nickel offers superior corrosion resistance in harsh environments, while zinc chromate is standard for general industrial use. Verify compatibility with your specific operating environment and any customer specifications.

Q: Do both parts support the same wire gauge range?

A: The Cinch 16-141 is specified for 14 AWG wire. The Molex 0387800116 accommodates 14-22 AWG, providing broader wire gauge compatibility. When substituting, ensure your wire gauge falls within both specifications (14 AWG minimum).

Q: What is the pitch spacing, and why does it matter?

A: Both parts feature 0.438" (11.12mm) pitch spacing, which determines the physical distance between circuit terminals. Identical pitch spacing ensures mechanical and electrical compatibility in PCB layouts and panel cutouts. This is a critical matching parameter for substitution.

Q: Are both parts RoHS compliant?

A: Yes. The Cinch 16-141 is RoHS Compliant, and the Molex 0387800116 is ROHS3 Compliant. Both meet current regulatory requirements for restricted substances in electrical and electronic equipment.
