Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0334810202 is determined by strict equivalence across the following critical parameters:

• Connector type (Plug)
• Contact type (Male Blade)
• Number of positions (2)
• Pitch specification (0.138" / 4.60mm)
• Number of rows (1)
• Mounting type (Free Hanging In-Line)
• Contact termination method (Crimp)
• Fastening type (Locking Ramp)
• Operating temperature range (-40°C ~ 150°C)
• Sealed feature requirement
• RoHS3 compliance

The substitute part 0334812202 maintains full electrical and mechanical compatibility with the original part across all specified parameters. The only difference is the housing color (Gray versus Black), which does not affect functional performance or interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0334812202 is the direct functional equivalent for the obsolete 0334810202. Both parts are manufactured by Molex within the same MX150 33481 series and maintain identical electrical and mechanical specifications across all critical parameters.

Selection of the 0334812202 is supported by:

• Active product status, ensuring continued availability and supply chain reliability
• Full ROHS3 compliance matching the original part
• Identical connector architecture, pitch, termination method, and temperature rating
• Sealed design maintaining environmental protection equivalent to the original

The housing color difference (Gray versus Black) is a cosmetic variation that does not impact functional performance, electrical characteristics, or mechanical interchangeability. Component selection should be based on application-specific requirements regarding visual identification or documentation standards.

Frequently Asked Questions (FAQ)

Q: Can the 0334812202 be used as a direct replacement for the 0334810202 in existing designs?

A: Yes. The 0334812202 maintains full electrical and mechanical compatibility across all functional parameters including connector type, contact configuration, pitch, termination method, temperature rating, and sealing features. The only difference is housing color.

Q: What is the significance of the product status change from Obsolete to Active?

A: The 0334812202 is an active product with confirmed inventory availability, ensuring reliable sourcing for new production and replacement applications. The 0334810202 is obsolete and no longer manufactured.

Q: Are there any material composition differences between these parts?

A: Both parts use polyamide (PA), nylon, and syndiotactic polystyrene (SPS) with glass filling. The material specifications are functionally equivalent.

Q: Does the color difference affect connector performance?

A: No. Housing color is a cosmetic attribute that does not affect electrical performance, mechanical fit, or environmental sealing characteristics.

Q: Are both parts RoHS compliant?

A: Yes. Both the 0334810202 and 0334812202 meet ROHS3 compliance requirements.

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

A: Both parts have a 0.138" (4.60mm) pitch. Pitch determines the spacing between contact positions and is a critical parameter for mechanical and electrical compatibility. Any deviation would prevent proper mating.

Q: Can contacts from one part be used with the housing of the other?

A: Contact compatibility is determined by the connector series (MX150 33481) and position count (2). Both parts accept the same contact specifications. Note that contacts are not included with these housings.
