Molex 0940304530 Quick Connect Female Crimp Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0940304530 is a 0.187" (4.75mm) Quick Connect Female Crimp Connector designed for 18-24 AWG wire applications. This non-insulated terminal is classified as obsolete, making equivalent substitute parts necessary for ongoing procurement and system maintenance. The part operates as a free-hanging in-line connector suitable for standard electrical termination applications requiring crimp attachment.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0940304530 is determined by strict alignment of the following critical parameters:

Tab Width: 0.187" (4.75mm) - mechanical interface requirement
Tab Thickness: 0.020" (0.51mm) - contact engagement specification
Termination Method: Crimp - assembly process compatibility
Gender: Female - connector polarity
Contact Material: Brass - electrical conductivity and corrosion resistance
Mounting Type: Free Hanging (In-Line) - installation configuration
Wire Gauge Compatibility: Minimum 18 AWG support required

Substitute parts must maintain these parameters within the specified tolerances. Wire gauge range may extend beyond the original specification provided the minimum 18 AWG requirement is met. Overall length and insulation diameter variations are acceptable when core electrical and mechanical interfaces remain compatible.

Engineering Selection Recommendations

Both TE Connectivity substitute parts meet the core electrical and mechanical requirements for direct replacement of the obsolete Molex 0940304530.

TE Connectivity 63347-1 is the manufacturer-recommended substitute. This part maintains ROHS3 compliance matching the original specification and operates within the 18-22 AWG range, which encompasses the primary operating window of the original part. Active product status ensures long-term availability and supply chain stability.

TE Connectivity 160778-2 provides an alternative with extended wire gauge support (16-24 AWG), offering broader application flexibility. This part carries RoHS compliance and active status. The extended lower gauge range (16 AWG) accommodates applications requiring heavier wire termination beyond the original specification.

Both substitutes are available in production quantities with established supply chains. Selection between these options depends on specific wire gauge requirements within your application.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 160778-2 replace Molex 0940304530 in all applications?

A: Yes, provided your application operates within the 18-24 AWG range. The 160778-2 supports 16-24 AWG, which fully encompasses the original specification. All critical mechanical and electrical parameters align: 0.187" tab width, 0.020" tab thickness, crimp termination, brass contact material, and free-hanging mounting configuration.

Q: What is the difference between TE Connectivity 63347-1 and 160778-2?

A: The primary difference is wire gauge range. The 63347-1 supports 18-22 AWG, while the 160778-2 supports 16-24 AWG. Both maintain identical tab dimensions, contact material, and termination method. The 63347-1 is the manufacturer-recommended direct substitute. Choose 160778-2 if your application requires 16 AWG or 24 AWG wire termination capability.

Q: Are packaging differences significant for component selection?

A: Packaging format (Tape & Reel for 160778-2 versus Cut Tape for 63347-1) affects procurement and handling but does not impact electrical or mechanical compatibility. Select based on your assembly process requirements and volume needs.

Q: Do all substitute parts maintain RoHS compliance?

A: Yes. The original Molex 0940304530 is ROHS3 compliant. TE Connectivity 63347-1 is ROHS3 compliant. TE Connectivity 160778-2 is RoHS compliant. Both substitutes meet environmental regulatory requirements.

Q: Is the contact finish difference between parts significant?

A: The Molex 0940304530 does not specify contact finish. TE Connectivity 160778-2 specifies tin finish, which provides enhanced corrosion resistance and solderability. This represents an improvement over unspecified finish and does not create compatibility issues.
