DF3-4EP-2C(20) Equivalent & Substitute Parts

Part Overview

The DF3-4EP-2C(20) is a 4-position rectangular connector housing manufactured by Hirose Electric Co Ltd, designed for applications requiring a plug-type connector with 2.00mm pitch. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system support, maintenance, and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DF3-4EP-2C(20) are identified based on strict parametric equivalence across the following critical dimensions:

• Connector Type & Contact Configuration: Plug housing with male pin contacts
• Position Count & Pitch: 4-position arrangement at 2.00mm (0.079") pitch
• Electrical Interface: Single-row, crimp-terminated contacts
• Mounting Specification: Free hanging in-line configuration
• Environmental Rating: MSL 1 (Unlimited moisture sensitivity level)

The Molex 0510060400 meets all these core parameters and qualifies as a parametric equivalent substitute. Variations in color (Natural vs. Black) and packaging format (Bulk vs. standard) do not affect functional interchangeability in applications where the connector housing and contact interface are the determining factors.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0510060400 is a direct parametric substitute for the DF3-4EP-2C(20). Both components are classified as obsolete, indicating limited availability through standard distribution channels. The Molex alternative carries ROHS3 compliance and REACH unaffected status, providing regulatory alignment for applications subject to these requirements.

Selection between these two parts should be based on:

• Availability: Current inventory status through authorized distributors
• Regulatory Compliance: ROHS3 and REACH requirements for the end application
• Color Specification: Confirm whether black (Hirose) or natural (Molex) color is functionally required
• Packaging Requirements: Bulk packaging (Molex) versus standard packaging format

Both components share identical electrical and mechanical specifications for the connector housing interface, ensuring functional compatibility in applications designed for either part number.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0510060400 directly replace the Hirose DF3-4EP-2C(20)?

A: Yes. Both components are 4-position plug housings with 2.00mm pitch, male pin contacts, and crimp termination. The parametric specifications are equivalent, making them functionally interchangeable in the connector housing application.

Q: Does the color difference (Black vs. Natural) affect compatibility?

A: Color is a cosmetic specification and does not affect electrical or mechanical compatibility. Selection should be based on application requirements and availability.

Q: What is the significance of the obsolete product status?

A: Obsolete status indicates both components are no longer in active production. Sourcing should prioritize current inventory availability through authorized distributors. Long-term supply planning may require evaluation of newer connector series from either manufacturer.

Q: Are contacts included with these connector housings?

A: No. Both the DF3-4EP-2C(20) and 0510060400 are housings only. Contacts must be sourced separately and are not included with the housing.

Q: What compliance certifications apply to the Molex substitute?

A: The Molex 0510060400 is ROHS3 compliant and REACH unaffected. Compliance documentation should be verified with the supplier for the specific application and regulatory jurisdiction.

Q: How do I verify that a substitute part will work in my application?

A: Confirm that your application requires a 4-position, 2.00mm pitch plug housing with male pin crimp contacts and free hanging in-line mounting. If these specifications match, the substitute is compatible. Verify contact compatibility separately, as contacts are not included with the housing.
