Molex 0511140410 Rectangular Connector Plug Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0511140410 is a 4-position rectangular connector plug housing from the Mighty-SPOX 51114 series, designed for panel mount applications with crimp contact termination. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and component procurement.

The connector features a 0.138" (4.60mm) pitch configuration with natural color polyester insulation material and operates across a temperature range of -40°C to 105°C. As an obsolete product, sourcing alternatives from the same series with active product status ensures long-term availability and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0511140410 is determined by strict alignment with the following critical parameters:

• Series Compatibility: Both parts must belong to the Mighty-SPOX 51114 series
• Connector Configuration: 4-position plug housing with male pin contacts
• Pitch Specification: 0.138" (4.60mm) contact spacing
• Mounting Interface: Panel mount capability
• Termination Method: Crimp contact termination
• Electrical Performance: Operating temperature range of -40°C to 105°C
• Physical Form Factor: Single-row rectangular connector housing

The substitute part 0511140410 meets all these criteria while offering active product status and improved material specifications, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0511140400 serves as the active equivalent for the obsolete 0511140410. Both components maintain identical electrical and mechanical specifications across all critical parameters: 4-position configuration, 0.138" pitch, male pin contacts, crimp termination, and -40°C to 105°C operating range.

The substitute part offers enhanced material composition with PBT insulation replacing polyester, providing improved chemical resistance and dimensional stability. The addition of snap-in mounting capability in the 0511140400 extends application flexibility while maintaining full panel mount compatibility.

The 0511140400 carries active product status with ROHS3 compliance certification, ensuring continued availability and regulatory alignment for new designs and production continuity. The MSL rating of 1 (Unlimited) indicates superior moisture handling characteristics compared to the original part's not-applicable designation.

Frequently Asked Questions (FAQ)

Q: Can the 0511140400 directly replace the 0511140410 in existing assemblies?

A: Yes. Both parts share identical connector type, position count, pitch, contact configuration, mounting interface, and operating temperature specifications. The 0511140400 maintains full functional and mechanical compatibility.

Q: What is the significance of the insulation material change from polyester to PBT?

A: PBT (Polybutylene Terephthalate) provides enhanced chemical resistance, improved dimensional stability, and superior moisture absorption characteristics compared to polyester. This material upgrade does not affect electrical or mechanical compatibility.

Q: Does the snap-in mounting feature in the 0511140400 affect panel mount compatibility?

A: No. The 0511140400 supports both panel mount and snap-in mounting options. Existing panel mount applications require no modification and function identically to the original part.

Q: Why is the 0511140410 classified as obsolete?

A: Product obsolescence reflects end-of-life status in the manufacturer's product line. The 0511140400 represents the active continuation within the same Mighty-SPOX 51114 series with equivalent functionality and improved specifications.

Q: What does ROHS3 compliance mean for this component?

A: ROHS3 compliance certifies that the component meets Restriction of Hazardous Substances Directive requirements, restricting specified hazardous materials. This certification is relevant for applications subject to environmental and regulatory compliance mandates.

Q: Are there any packaging differences between these parts?

A: The 0511140410 packaging is not specified. The 0511140400 is supplied in bag packaging. Verify packaging requirements for your procurement and assembly processes.
