Molex 0430201811 Equivalent & Substitute Parts

Part Overview

The Molex 0430201811 is an 18-position rectangular connector housing designed for the Micro-Fit 3.0 series. This plug housing accommodates male pin contacts with a 0.118" (3.00mm) pitch and is configured in a 2-row arrangement. The connector features a locking ramp fastening mechanism and is rated for operating temperatures between -40°C and 105°C. This part is actively manufactured and widely used in applications requiring compact, reliable interconnection solutions. Substitute parts may be required due to supply chain considerations, inventory availability, or design standardization across manufacturing platforms.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0430201811 is based on strict electrical and mechanical parameter alignment. The following criteria determine interchangeability:

Critical Parameters for Substitution:

• 18-position configuration with 0.118" (3.00mm) pitch
• 2-row arrangement with matching row spacing
• Plug housing with male pin contact accommodation
• Locking ramp fastening mechanism
• Free hanging (in-line) mounting orientation
• Crimp contact termination compatibility
• Operating temperature range of -40°C to 105°C minimum
• Black color specification
• Glow wire compliance

The substitute part Amphenol ICC (FCI) 10127717-18LF meets all these parameters within the Minitek® Pwr 3.0 series, establishing a direct parametric equivalent relationship.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0430201811 and Amphenol ICC (FCI) 10127717-18LF are active products with current manufacturing status. The Molex part carries ROHS3 compliance, while the Amphenol ICC (FCI) part carries RoHS compliance with additional REACH affected status documentation. Both parts meet glow wire requirements and maintain identical operating temperature specifications.

Selection between these parts should be based on:

• Supply chain availability and lead time requirements
• Existing design platform standardization (Micro-Fit 3.0 versus Minitek® Pwr 3.0 series)
• Packaging format preference (Bulk versus Bag)
• Compliance documentation requirements for specific applications
• Inventory levels and procurement cost considerations

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC (FCI) 10127717-18LF directly replace the Molex 0430201811 in existing designs?

A: Yes. Both parts share identical electrical and mechanical parameters including 18-position configuration, 0.118" (3.00mm) pitch, 2-row arrangement, locking ramp fastening, and operating temperature range. The insulation material composition differs slightly (PA versus PA66), but both are polyamide-based nylon materials suitable for the same thermal and environmental conditions.

Q: What is the difference between ROHS3 and RoHS compliance?

A: ROHS3 represents the third iteration of the Restriction of Hazardous Substances directive with updated substance restrictions. RoHS compliance indicates adherence to the directive. Both designations confirm the absence of restricted hazardous materials. The Amphenol ICC (FCI) part includes additional REACH affected status documentation.

Q: Are the contacts interchangeable between these two housing types?

A: Both housings accommodate crimp-terminated male pin contacts with 0.118" (3.00mm) pitch specifications. Contact compatibility depends on the specific contact part number and series designation. Verify contact part numbers separately to ensure mechanical and electrical compatibility.

Q: What is the significance of Moisture Sensitivity Level 1?

A: MSL 1 indicates unlimited shelf life without moisture control requirements. Both parts can be stored and handled under standard conditions without desiccant packaging or moisture barrier protection.

Q: How do the packaging formats (Bulk versus Bag) affect component handling?

A: Bulk packaging typically provides cost advantages for high-volume procurement, while bag packaging may offer better moisture protection and traceability for smaller quantities. Both formats are suitable for the same applications; selection depends on procurement volume and inventory management practices.
