Substitute Part Grouping Explanation

Substitute parts for the Cinch Connectivity Solutions 4-141 are identified based on strict equivalence of the following critical parameters:

• Number of circuits: 4
• Pitch spacing: 0.438" (11.12mm)
• Terminal block type: Barrier block
• Top termination method: Screws
• Barrier construction: 2 Wall (Dual)
• Mounting capability: Chassis and Panel
• RoHS compliance: ROHS3 Compliant

The Molex 0387800104 meets these core substitution criteria. Variations in current rating, voltage rating, wire gauge range, insulation material, and terminal screw finish do not preclude substitution when the application electrical requirements fall within the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the Cinch Connectivity Solutions 4-141 and Molex 0387800104 are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

The Cinch 4-141 provides a 20A current rating at 250V, suitable for applications requiring this specific current capacity. The Molex 0387800104 operates at 15A maximum current with a higher 300V voltage rating and accepts wire gauges from 14-22 AWG, providing broader wire gauge compatibility.

Selection between these parts depends on application current and voltage requirements. The Cinch part is appropriate for circuits requiring 20A capacity. The Molex part is suitable for applications operating at or below 15A with voltage requirements up to 300V. Both parts share identical mechanical form factor, pitch spacing, circuit count, and mounting configuration, ensuring physical and electrical interchangeability within their respective current and voltage operating ranges.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0387800104 directly replace the Cinch 4-141 in all applications?

A: Direct replacement is valid only when the application current requirement does not exceed 15A. The Molex part has a lower current rating (15A vs. 20A). If the circuit requires 20A capacity, the Cinch 4-141 is the appropriate selection. Both parts operate at compatible voltage levels and share identical mechanical specifications.

Q: What are the key differences between these two barrier block connectors?

A: The primary differences are current rating (Cinch 20A vs. Molex 15A), voltage rating (Cinch 250V vs. Molex 300V), wire gauge range (Cinch 14 AWG only vs. Molex 14-22 AWG), insulation material (Cinch phenolic vs. Molex thermoplastic), and terminal screw finish (Cinch nickel vs. Molex zinc with clear chromate). All other specifications including circuit count, pitch, barrier type, and mounting configuration are identical.

Q: Are both parts RoHS compliant?

A: Yes, both the Cinch 4-141 and Molex 0387800104 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component procurement.

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

A: Both parts have a 0.438" (11.12mm) pitch spacing, which defines the center-to-center distance between circuits. Identical pitch spacing ensures that both connectors can be used in applications with the same PCB layout and panel cutout dimensions, making them mechanically interchangeable.

Q: Can I use the Molex part with wire gauges larger than 14 AWG?

A: Yes, the Molex 0387800104 accepts wire gauges from 14-22 AWG, providing flexibility for applications using larger diameter conductors. The Cinch 4-141 is specified for 14 AWG wire gauge only.
