Molex 0934452203 Rectangular Connector Plug Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0934452203 is a 3-position rectangular connector plug housing from the ML-XT 93445 series, designed for applications requiring IP68-rated environmental sealing. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system support and new design implementations. The housing accommodates female socket contacts via crimp termination and features a latch lock fastening mechanism suitable for free-hanging inline mounting configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0934452203 is determined by the following critical parameters:

• Connector Type & Contact Configuration: Plug housing with female socket contacts
• Position Count & Row Configuration: 3-position, 2-row arrangement
• Termination Method: Crimp contact termination
• Fastening Mechanism: Latch lock engagement system
• Environmental Rating: IP68 sealing capability
• Mounting Style: Free-hanging inline configuration
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The substitute part DT06-3S from TE Connectivity Deutsch Connectors satisfies all mandatory substitution criteria. While color differs (gray versus green), this represents a cosmetic variation that does not affect functional compatibility. The substitute maintains identical electrical and mechanical interface specifications, enabling direct functional replacement in applications where the original part is no longer available.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity Deutsch Connectors DT06-3S represents a functionally equivalent substitute for the obsolete Molex 0934452203. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing environments.

The DT06-3S provides enhanced environmental protection through dual IP68 and IP6K9K ratings, exceeding the original part's IP68 specification. This enhancement does not introduce compatibility issues and may provide additional margin for applications subject to high-pressure water jet exposure.

Operating temperature range specification (-55°C ~ 125°C) is provided for the substitute part and represents standard performance parameters for this connector class. Both components employ identical mechanical interfaces: crimp termination, latch lock fastening, and free-hanging inline mounting configuration.

The color difference (gray versus green) is a cosmetic distinction that does not affect electrical or mechanical function. System designers should verify that color-coding requirements in their applications do not mandate the original green housing specification.

Frequently Asked Questions (FAQ)

Q: Can the DT06-3S directly replace the Molex 0934452203 in existing assemblies?

A: Yes. Both components share identical connector type, contact configuration, position count, row arrangement, termination method, and fastening mechanism. The substitute maintains full mechanical and electrical compatibility.

Q: Does the gray color of the DT06-3S affect compatibility?

A: Color is a cosmetic attribute that does not impact functional performance. If color-coding serves a system identification or safety function in your application, verify that gray housing is acceptable for your use case.

Q: What is the significance of the DT06-3S featuring both IP68 and IP6K9K ratings?

A: IP6K9K represents protection against high-pressure water jet exposure, a more stringent environmental requirement than standard IP68 sealing. The substitute part exceeds the original specification, providing enhanced environmental protection without introducing compatibility concerns.

Q: Are contacts included with either housing?

A: No. Both the Molex 0934452203 and TE Connectivity DT06-3S are supplied as housings only. Contacts must be sourced separately and crimped into the housing according to manufacturer specifications.

Q: What regulatory compliance status applies to both parts?

A: Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: Are there additional substitute options beyond the DT06-3S?

A: The provided data identifies DT06-3S as the primary substitute. The DT06-3S documentation references additional variants (DT06-3S-E004, AT06-3S); however, detailed compatibility parameters for these alternatives are not provided in the current reference data.
