Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0334810203 is determined by strict equivalence across the following critical parameters:

• Connector type (Plug)
• Number of positions (2)
• Pitch specification (0.138" / 4.60mm)
• Contact type (Male Blade)
• Number of rows (1)
• Mounting type (Free Hanging In-Line)
• Contact termination method (Crimp)
• Fastening type (Locking Ramp)
• Sealed feature requirement
• Operating temperature range (-40°C ~ 150°C)

Two substitute parts meet these criteria: the Molex 0334812203 (MFR Recommended, Active status) and the Molex 0334810202 (Parametric Equivalent, Obsolete status). Both maintain identical electrical and mechanical specifications with the exception of housing color and certain material composition details.

Parameter Comparison

Engineering Selection Recommendations

For new designs and ongoing production requiring the Molex 0334810203 specification, the Molex 0334812203 is the primary substitute. This part maintains active product status with Molex, ensuring continued availability and supply chain support. Both the main part and substitute are ROHS3 compliant and share identical electrical and mechanical parameters across all critical connector specifications.

The Molex 0334810202 serves as a secondary parametric equivalent, maintaining full functional compatibility with identical connector specifications. However, this part carries obsolete status, making it unsuitable for long-term supply assurance. The primary distinction between 0334812203 and 0334810202 is housing color (gray versus black), which does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0334812203 directly replace the 0334810203 in existing assemblies?

A: Yes. The 0334812203 maintains identical specifications across all critical parameters: 2-position configuration, 4.60mm pitch, male blade contacts, crimp termination, locking ramp fastening, and sealed design. Both operate across the -40°C to 150°C temperature range.

Q: What is the significance of the color difference between 0334810203 (gray) and 0334810202 (black)?

A: Housing color is a cosmetic parameter that does not affect electrical or mechanical performance. Both parts are functionally equivalent for connector applications. Color selection should be based on design aesthetics or assembly identification requirements only.

Q: Why is the 0334812203 recommended over the 0334810202?

A: The 0334812203 carries active product status with Molex, ensuring ongoing manufacturing support and supply availability. The 0334810202 is classified as obsolete, presenting potential long-term supply risks.

Q: Are there packaging differences between these parts?

A: The main part 0334810203 has unspecified packaging. Both substitute parts (0334812203 and 0334810202) are supplied in bulk packaging. Packaging format does not affect connector performance or compatibility.

Q: Do all three parts meet the same compliance standards?

A: Yes. The 0334810203, 0334812203, and 0334810202 are all ROHS3 compliant. Moisture sensitivity level (MSL) differs between parts, but this parameter applies to storage and handling rather than operational performance.
