Molex 0190030030 Quick Connect Female Crimp Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0190030030 is a 0.110" (2.79mm) Quick Connect Female Crimp Connector rated for 18-22 AWG wire gauges with full insulation. This terminal is part of the InsulKrimp series and is designed for free-hanging, in-line applications requiring serrated termination. The part maintains active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified to address inventory availability, packaging format preferences, or supply chain requirements while maintaining electrical and mechanical compatibility within the specified parameter tolerances.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0190030030 is determined by strict alignment with the following critical parameters:

Tab Width Compatibility: Primary tab width of 0.110" (2.79mm) is mandatory. Substitute parts may accommodate dual tab widths (0.110" and 0.125") provided the 0.110" specification is supported.
Wire Gauge Range: 18-22 AWG requirement must be maintained without deviation.
Termination Method: Crimp termination is required; no alternative termination types are acceptable.
Gender and Insulation: Female gender with full insulation is non-negotiable.
Contact Material and Finish: Brass contact material with compatible finish (Electro-Tin or Tin) maintains electrical performance.
Compliance Standards: ROHS3 compliance is required; MSL 1 rating is standard across all qualified substitutes.

The two identified substitute parts (TE Connectivity 2-520272-2 and 2-520273-2) meet all mandatory electrical and mechanical parameters while differing in packaging format and inventory availability.

Engineering Selection Recommendations

Both TE Connectivity substitute parts maintain full electrical and mechanical compatibility with the Molex 0190030030 based on provided specifications. Selection between alternatives should be based on the following factors:

TE Connectivity 2-520272-2 (Cut Tape Packaging): Suitable for applications requiring smaller order quantities or automated assembly line integration. Cut tape format supports pick-and-place equipment compatibility. Inventory availability is 2,300 pieces.

TE Connectivity 2-520273-2 (Bulk Packaging): Appropriate for high-volume production runs or applications matching the original bulk packaging format. Significantly higher inventory availability (84,842 pieces) supports extended production schedules without supply interruption.

All three parts maintain ROHS3 compliance and MSL 1 rating. Contact finish differences (Electro-Tin versus Tin) are within acceptable industry tolerances for brass-based quick connect terminals in this application class.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 2-520272-2 and 2-520273-2 be used interchangeably with Molex 0190030030?

A: Yes. Both TE Connectivity parts meet the mandatory electrical and mechanical parameters: 0.110" tab width, 0.032" tab thickness, 18-22 AWG wire gauge rating, crimp termination, female gender, and full insulation. The primary difference is packaging format (Cut Tape versus Bulk).

Q: What is the significance of the dual tab width specification (0.110" and 0.125") on TE Connectivity substitutes?

A: TE Connectivity parts accommodate both 0.110" and 0.125" tab widths. For applications requiring only the 0.110" specification, the TE Connectivity connectors remain fully compatible. The additional 0.125" capability does not affect performance in 0.110" applications.

Q: Are there dimensional differences that affect mechanical fit?

A: Yes. Overall length differs: Molex 0190030030 measures 0.780" (19.81mm) while TE Connectivity substitutes measure 0.735" (18.67mm). Insulation diameter also varies: Molex 0.135" (3.43mm) versus TE Connectivity 0.120" (3.05mm). These differences are within acceptable tolerances for free-hanging, in-line mounting applications but should be verified against specific connector housing or receptacle specifications.

Q: What packaging format should be selected for production?

A: Cut Tape (CT) format (2-520272-2) is optimized for automated assembly and smaller batch quantities. Bulk format (2-520273-2) is suitable for high-volume manual assembly or applications where packaging format matches existing supply chain processes.

Q: Are compliance certifications equivalent across all three parts?

A: Yes. All three parts maintain ROHS3 compliance, MSL 1 rating, and EAR99 ECCN classification. REACH status differs (Molex: REACH Unaffected; TE Connectivity: Vendor Undefined), but this does not affect electrical or mechanical substitution eligibility.
