Molex 0386006604 Equivalent & Substitute Parts
Part Overview
The Molex 0386006604 is a 4-circuit barrier block connector with 0.250" (6.35mm) pitch, designed for through-hole mounting with screw termination on the top and PC pin termination on the bottom. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. The barrier block configuration provides electrical isolation between circuits with a 3-wall (tri) barrier design, supporting 10A current at 300V across 18-22 AWG wire gauges.

Engineering Selection Recommendations
The TE Connectivity AMP Connectors 3PCV-04-006 is the documented equivalent substitute for the obsolete Molex 0386006604. Both components maintain identical electrical specifications (10A at 300V), mechanical configuration (4-circuit, 0.250" pitch barrier block), and compliance certifications (UL94 V-0, ROHS3). The TE Connectivity part is currently in active production status, ensuring long-term availability and supply chain continuity.
The primary design difference is the addition of a captive plate on the screw termination of the TE Connectivity part, which provides enhanced mechanical retention during assembly. This feature is compatible with the original application requirements and does not introduce functional incompatibility.
Both components support identical wire gauge ranges (18-22 AWG) and through-hole mounting methods, enabling direct substitution in existing PCB designs without layout modifications.
Frequently Asked Questions (FAQ)
Q: Can the TE Connectivity 3PCV-04-006 be used as a direct replacement for the Molex 0386006604?
A: Yes. Both parts meet identical electrical ratings (10A, 300V), circuit configuration (4-circuit), pitch (0.250"), and compliance standards (UL94 V-0, ROHS3). The TE Connectivity part is functionally equivalent and maintains through-hole mounting compatibility.
Q: What is the difference between the screw termination on these two parts?
A: The Molex 0386006604 features standard screws, while the TE Connectivity 3PCV-04-006 includes a captive plate design. The captive plate provides additional mechanical retention during assembly but does not affect electrical performance or circuit isolation.
Q: Are the PC pin configurations identical?
A: Yes. Both parts use PC pin bottom termination with identical spacing and electrical characteristics, ensuring compatibility with existing PCB footprints.
Q: What wire gauges are supported by the substitute part?
A: The TE Connectivity 3PCV-04-006 supports 18-22 AWG wire gauges, matching the original Molex specification.
Q: Is the operating temperature range the same?
A: The Molex 0386006604 operates from -40°C to 130°C. The TE Connectivity 3PCV-04-006 operates to 120°C maximum. For applications requiring the full -40°C to 130°C range, verify thermal requirements against the 120°C upper limit of the substitute part.
Q: Are both parts RoHS compliant?
A: Yes. Both the Molex 0386006604 and TE Connectivity 3PCV-04-006 are ROHS3 compliant.
