Molex 0050361808 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0050361808 is an active-status rectangular connector header designed for through-hole, right-angle board-to-cable/wire applications. This shrouded 12-position connector with 4.2mm pitch serves general purpose, industrial, and telecommunications applications. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component interchange based on matching electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0050361808 is determined by the following critical parameters that must match or be compatible:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (12)
• Number of rows (2)
• Pitch - mating (0.165" / 4.20mm)
• Row spacing - mating (0.165" / 4.20mm)
• Mounting type (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Contact material (Brass)
• Insulation material (Polyamide PA66 / Nylon 6/6)
• Fastening type (Locking Ramp)

The substitute part Amphenol ICC (FCI) 10127819-12211LF meets all these critical parameters, enabling direct functional interchange in applications where the Molex connector is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0050361808 and Amphenol ICC 10127819-12211LF are active-status products with full RoHS compliance and unlimited moisture sensitivity ratings. The Amphenol ICC substitute offers a higher material flammability rating (UL94 V-0 versus V-2), which may provide additional safety margin in applications with elevated flammability requirements. Minor dimensional variations in contact post length (0.142" versus 0.138") and insulation height (0.378" versus 0.386") fall within acceptable tolerance ranges for standard through-hole solder applications. Both parts share identical pitch, row spacing, shrouding, and fastening specifications, ensuring mechanical and electrical compatibility in board-to-cable/wire interconnect designs.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 10127819-12211LF be used as a direct replacement for the Molex 0050361808?

A: Yes. Both connectors share identical mating pitch (4.20mm), row spacing (4.20mm), position count (12), row configuration (2), mounting type (through-hole right-angle), shrouding (4-wall), termination method (solder), contact material (brass), and fastening mechanism (locking ramp). The minor dimensional differences in post length and insulation height do not affect functional compatibility in standard applications.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on matching connector type, contact type, position count, row configuration, mating pitch, row spacing, mounting orientation, shrouding design, termination method, contact material, insulation material, and fastening type. All these parameters must align between the primary and substitute parts.

Q: Are there compliance differences between these two connectors?

A: Both parts are RoHS compliant and carry unlimited moisture sensitivity ratings. The Amphenol ICC part achieves UL94 V-0 flammability rating compared to the Molex part's UL94 V-2 rating, indicating superior flame resistance characteristics.

Q: Do the dimensional variations affect PCB layout or mating compatibility?

A: No. The contact post length difference (0.142" versus 0.138") and insulation height difference (0.378" versus 0.386") are minor and do not impact standard through-hole solder joint formation or mating interface compatibility with corresponding receptacle connectors.

Q: What is the packaging format for both parts?

A: Both the Molex 0050361808 and Amphenol ICC 10127819-12211LF are supplied in tray packaging suitable for automated assembly and component handling.
