Equivalent & Substitute Parts for Molex 0190030021

Part Overview

The Molex 0190030021 is a 0.187" (4.75mm) Quick Connect Female 18-22 AWG Crimp Connector with full insulation, part of the InsulKrimp series. This terminal is designed for in-line, free-hanging applications requiring secure crimp termination on wire gauges between 18 and 22 AWG. The part maintains Active product status and is fully compliant with RoHS3 and REACH regulations. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the critical dimensions and performance specifications.

Substitute Part Grouping Explanation

Substitute parts for the Molex 0190030021 are qualified based on strict equivalence of the following critical parameters:

Tab Width: 0.187" (4.75mm)
Tab Thickness: 0.032" (0.81mm)
Wire Gauge: 18-22 AWG
Gender: Female
Termination: Crimp
Insulation: Fully Insulated
Contact Material: Brass
Insulation Diameter: 0.230" (5.84mm)
Mounting Type: Free Hanging (In-Line)

The identified substitutes are TE Connectivity AMP Connectors part numbers 2-520274-2 and 2-520275-2 from the Ultra-Fast series. Both parts maintain all critical electrical and mechanical parameters required for direct substitution. Variations in overall length (0.935" versus 0.860") and contact finish (Tin versus Electro-Tin) do not affect functional compatibility within the specified application parameters.

Engineering Selection Recommendations

Both TE Connectivity substitute parts maintain Active product status and full RoHS3 compliance, ensuring regulatory alignment with the original Molex 0190030021. The electrical and mechanical specifications are equivalent across all critical parameters governing connector performance and wire termination.

TE Connectivity 2-520274-2 is available in Cut Tape packaging with 129,646 units in stock, suitable for high-volume production environments. TE Connectivity 2-520275-2 is available in Bulk packaging with 19,781 units in stock, appropriate for applications requiring standard packaging formats.

The overall length differential (0.935" versus 0.860") reflects series design variations between InsulKrimp and Ultra-Fast architectures but does not compromise functional substitution when tab width, thickness, wire gauge, and insulation parameters remain constant. Contact finish variation (Tin versus Electro-Tin) does not affect electrical performance within the specified application scope.

Frequently Asked Questions (FAQ)

Q: What determines whether a part can substitute for the Molex 0190030021?

A: Substitution is based on equivalence of tab width (0.187"), tab thickness (0.032"), wire gauge (18-22 AWG), gender (Female), termination type (Crimp), insulation type (Fully Insulated), contact material (Brass), insulation diameter (0.230"), and mounting type (Free Hanging In-Line). All identified substitutes meet these criteria.

Q: Does the difference in overall length affect compatibility?

A: No. The overall length variation between the Molex part (0.860") and TE Connectivity substitutes (0.935") reflects series design differences but does not impact functional compatibility when all critical electrical and mechanical parameters remain equivalent.

Q: Are there packaging differences between the substitute parts?

A: Yes. TE Connectivity 2-520274-2 is supplied in Cut Tape packaging, while 2-520275-2 is supplied in Bulk packaging. Both are equivalent electrically and mechanically; packaging selection depends on production workflow requirements.

Q: Do the substitute parts meet the same regulatory standards?

A: Yes. Both TE Connectivity substitutes are ROHS3 Compliant with MSL Rating 1 (Unlimited), matching the regulatory status of the original Molex 0190030021.

Q: What is the significance of the color difference (Pink versus Red)?

A: Color is a visual identifier only and does not affect electrical or mechanical performance. The color difference reflects manufacturer series conventions and does not impact functional substitution.
