Molex 0511110310 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0511110310 is a 3-position receptacle housing for rectangular connectors with a 2.50mm pitch. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement. The housing is designed for crimp contact termination with latch lock fastening, suitable for free hanging in-line and panel mount applications. Due to its obsolete status, active equivalent parts are required to maintain design continuity and ensure component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0511110310 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle housing with female socket contacts
• Position Count & Pitch: 3-position arrangement at 0.098" (2.50mm) pitch
• Termination Method: Crimp contact termination
• Fastening Mechanism: Latch lock fastening system
• Mounting Compatibility: Free hanging in-line and panel mount capability
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The substitute part Molex 5005920300 meets all these critical parameters. While color differs (natural vs. white), this is a non-functional variation that does not affect electrical or mechanical compatibility. The substitute is from the active CP-2.5 500592 series, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The Molex 5005920300 is the direct functional equivalent for the obsolete 0511110310. Selection of this substitute is based on:

• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring continued regulatory alignment
• Product Status: The substitute is an active part from the CP-2.5 500592 series, providing assured long-term availability and manufacturing support
• Functional Equivalence: All critical electrical and mechanical parameters are identical, including connector type, position count, pitch, termination method, and fastening mechanism
• Inventory Availability: The substitute part maintains substantial stock levels (6390 pcs), supporting immediate procurement requirements

The color difference (natural vs. white) represents a cosmetic variation with no impact on electrical performance or mechanical function.

Frequently Asked Questions (FAQ)

Q: Can the Molex 5005920300 be used as a direct replacement for the 0511110310?

A: Yes. Both parts are 3-position receptacle housings with 2.50mm pitch, crimp termination, and latch lock fastening. All functional parameters are equivalent. The only difference is housing color (natural vs. white), which does not affect compatibility.

Q: Why is the original part obsolete?

A: The 0511110310 has been discontinued by Molex. The 5005920300 from the active CP-2.5 500592 series provides the same functionality with ongoing manufacturer support.

Q: Are there any compliance concerns with substitution?

A: No. Both parts are ROHS3 compliant and REACH unaffected. Regulatory status remains unchanged with this substitution.

Q: Does the color difference affect performance?

A: No. Color is a cosmetic attribute. The natural color of the substitute part does not impact electrical performance, mechanical fit, or functional compatibility.

Q: What is the pitch specification, and why is it important for substitution?

A: Pitch is the center-to-center distance between contact positions, specified as 0.098" (2.50mm) for both parts. Pitch must match exactly for proper mating with corresponding plug connectors. Both parts share identical pitch specifications.

Q: Are contacts included with these housings?

A: No. Both the original and substitute parts are housings only. Crimp contacts must be sourced separately and are not included with the housing.

Q: What mounting configurations are supported?

A: Both parts support free hanging in-line mounting. The original part also lists panel mount capability; verify specific panel mount requirements against the substitute's mechanical drawing if panel mounting is required for your application.
