Molex 0334861959 Rectangular Connector Plug Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0334861959 is a 16-position rectangular connector plug housing with 4.60mm pitch, designed for crimp contact termination in free-hanging inline applications. This component is classified as obsolete, necessitating identification of active equivalent alternatives to maintain supply chain continuity and support ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0334861959 is determined by the following critical parameters:

• Connector Type & Contact Configuration: Plug housing with male blade contacts
• Position Count & Pitch: 16 positions at 0.138" (4.60mm) pitch
• Mechanical Interface: 2-row configuration with free-hanging inline mounting
• Termination Method: Crimp contact termination with locking ramp fastening
• Environmental Sealing: Sealed housing design
• Regulatory Compliance: ROHS3 compliance and MSL rating

Two substitute parts meet these criteria with variations in color and operating temperature range:

Direct Manufacturer Substitute (0349861959): Functionally equivalent 16-position plug housing with identical mechanical and electrical parameters. Color variation (black) and pitch specification not explicitly stated in documentation.

Parametric Equivalent (0334828601): Full parameter alignment including 4.60mm pitch specification, 2-row configuration, and sealed design. Extended operating temperature range (-40°C to 150°C versus -40°C to 125°C for main part). REACH status differs (affected versus unaffected).

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: Molex 0334828601

This part provides complete parametric equivalence with the obsolete 0334861959, including explicit 4.60mm pitch and 2-row configuration specifications. Active product status ensures ongoing availability. The extended operating temperature range (-40°C to 150°C) provides superior thermal performance compared to the original specification. ROHS3 compliance is maintained. The REACH affected status requires verification against specific application regulatory requirements but does not preclude substitution in compliant applications.

Secondary Option: Molex 0349861959

This active substitute maintains 16-position plug housing configuration with identical mechanical interface and crimp termination. Pitch and row spacing specifications are not explicitly documented, requiring confirmation against application requirements before deployment. Active product status supports supply chain continuity.

Both substitutes maintain sealed housing design, locking ramp fastening, and ROHS3 compliance. Selection between alternatives depends on documented pitch and row spacing requirements for the specific application circuit.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0349861959 directly replace the 0334861959 in existing assemblies?

A: The 0349861959 maintains identical connector type, position count, mounting configuration, and termination method. However, pitch and row spacing specifications are not provided in available documentation. Confirmation of 4.60mm pitch compatibility is required before substitution.

Q: What is the primary difference between the two substitute parts?

A: The 0334828601 provides complete specification alignment including explicit 4.60mm pitch and 2-row configuration. The 0349861959 omits pitch and row spacing documentation. The 0334828601 also specifies extended operating temperature range (-40°C to 150°C).

Q: Does the color difference (gray to black) affect electrical performance?

A: Color is a cosmetic parameter that does not affect electrical or mechanical function. Both substitute parts maintain sealed housing design and identical contact configuration.

Q: Are there REACH compliance considerations for substitution?

A: The 0334828601 is REACH affected, while the original part is REACH unaffected. Applications subject to REACH regulations must verify compliance status against specific substance restrictions. The 0349861959 maintains REACH unaffected status.

Q: What packaging formats are available for the substitute parts?

A: The 0349861959 is supplied in bulk packaging. The 0334828601 is supplied in bulk packaging. Packaging format does not affect functional compatibility.

Q: Are contacts included with these connector housings?

A: All three parts (main and substitutes) are supplied as housings only. Crimp contacts must be sourced separately and are not included.
