Molex 0940304540 Quick Connect Female Crimp Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0940304540 is a 0.187" (4.75mm) Quick Connect Female Crimp Connector designed for 10-24 AWG wire gauges. This non-insulated terminal operates as a free-hanging in-line connector with brass contact material. The part is classified as obsolete, making identification of suitable substitutes essential for ongoing design support and procurement continuity. Equivalent parts must maintain compatibility across tab dimensions, termination method, and mounting configuration while accommodating wire gauge specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0940304540 is determined by the following critical parameters:

Mandatory Matching Parameters:

Tab Width: 0.187" (4.75mm)
Tab Thickness: 0.020" (0.51mm)
Tab Length: 0.248" (6.30mm)
Gender: Female
Termination Method: Crimp
Mounting Type: Free Hanging (In-Line)
Contact Material: Brass
Insulation Type: Non-Insulated

Allowable Variation Parameters:

Wire Gauge: 10-24 AWG (original) to 14-18 AWG (substitute) — represents a subset of the original range
Contact Finish: May differ from original specification
Insulation Diameter: Acceptable within specified ranges for wire gauge compatibility

The substitute part TE Connectivity AMP Connectors 1217149-1 maintains all mandatory matching parameters while operating within a narrower wire gauge specification (14-18 AWG), which falls within the original 10-24 AWG range.

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 1217149-1 qualifies as a direct substitute for the obsolete Molex 0940304540 based on the following engineering criteria:

Mechanical Compatibility: All tab dimensions (width, thickness, and length) are identical, ensuring proper mating with existing receptacles and connectors designed for the original part.

Electrical Compatibility: Both parts utilize brass contact material with crimp termination, maintaining equivalent electrical performance characteristics for the intended application.

Compliance Status: The substitute part maintains ROHS3 compliance, matching the regulatory status of the original component. The substitute is currently in active production status, ensuring long-term availability and supply chain continuity.

Wire Gauge Consideration: The substitute operates within the 14-18 AWG range, which is a subset of the original 10-24 AWG specification. Applications utilizing wire gauges 14-18 AWG are fully compatible. Applications requiring 10-12 AWG wire gauges must evaluate alternative substitutes or confirm compatibility with the narrower gauge range.

Packaging: The substitute is available in Cut Tape (CT) packaging, supporting both automated and manual assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1217149-1 replace the Molex 0940304540 in all applications?

A: The TE Connectivity 1217149-1 is compatible with applications using wire gauges 14-18 AWG. Applications requiring 10-12 AWG wire gauges must evaluate alternative substitutes, as the substitute part operates only within the 14-18 AWG range.

Q: Are the tab dimensions identical between the two parts?

A: Yes. Both parts feature 0.187" (4.75mm) tab width, 0.020" (0.51mm) tab thickness, and 0.248" (6.30mm) tab length, ensuring mechanical interchangeability.

Q: What is the difference in insulation diameter between the two parts?

A: The Molex 0940304540 accommodates insulation diameters of 0.110" ~ 0.169" (2.79mm ~ 4.29mm), while the TE Connectivity 1217149-1 accommodates 0.110" ~ 0.160" (2.79mm ~ 4.06mm). The substitute part has a slightly narrower upper limit, which is acceptable for wire gauges 14-18 AWG.

Q: Is the substitute part currently available?

A: Yes. The TE Connectivity 1217149-1 is classified as active product status with 69,843 pieces in stock, providing reliable supply chain availability compared to the obsolete Molex part.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both the Molex 0940304540 and TE Connectivity 1217149-1 are ROHS3 compliant.

Q: What packaging options are available for the substitute part?

A: The TE Connectivity 1217149-1 is supplied in Cut Tape (CT) packaging, suitable for both automated pick-and-place assembly and manual component handling.
