Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0348406040 are qualified based on strict electrical and mechanical parameter equivalence within the MX150 34840 series. All substitute parts maintain identical specifications across the following critical parameters:

• 12-position connector configuration
• 0.138" (4.60mm) pitch spacing
• 2-row layout with 0.236" (6.00mm) row spacing
• Male blade contact type
• Crimp termination method
• Twist latch fastening mechanism
• Panel mount and bulkhead mounting capability
• IP67K sealing rating
• Syndiotactic Polystyrene (SPS) glass-filled insulation
• ROHS3 compliance and EAR99 export classification

Substitute parts are differentiated by product status (active versus obsolete), color variant (gray or black), and packaging configuration. All substitutes are manufactured by Molex and belong to the same base product family (034840).

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts (0348406440, 0348406410, 0348406420, 0348406430) are active production components manufactured by Molex and maintain full electrical and mechanical compatibility with the obsolete 0348406040. Selection among these substitutes should be based on the following criteria:

Product Status: All substitutes are active production parts, eliminating supply chain risk associated with the obsolete main part number.

Compliance: All substitutes maintain ROHS3 compliance and EAR99 export classification, matching the regulatory requirements of the original part.

Color Selection: Three substitutes (0348406440, 0348406420, 0348406430) are available in gray to match the original part color. The 0348406410 variant is available in black for applications where color differentiation is required.

Packaging: All substitutes are supplied in bulk packaging, suitable for production and assembly environments.

Operating Temperature: Substitute parts specify operating temperature range of -40°C to 125°C, providing defined thermal performance parameters absent from the original part specification.

Frequently Asked Questions (FAQ)

Q: Are all substitute parts mechanically interchangeable with the 0348406040?

A: Yes. All substitute parts maintain identical mechanical dimensions, pitch spacing, row configuration, mounting type, and fastening mechanism. Direct substitution is supported without design modification.

Q: What is the difference between the gray and black color variants?

A: The 0348406410 is supplied in black insulation material, while 0348406440, 0348406420, and 0348406430 are supplied in gray. All other electrical and mechanical parameters are identical. Color selection depends on application requirements and visual identification needs.

Q: Why is the original part 0348406040 classified as obsolete?

A: The original part is obsolete, but all substitute parts are active production components from the same MX150 34840 series. This ensures continued availability and supply chain stability for new designs and maintenance applications.

Q: Do the substitute parts include contacts?

A: No. All parts in this series, including the main part and all substitutes, are connector housings only. Contacts must be sourced separately and are not included with the housing.

Q: Are there any differences in compliance or certification between the main part and substitutes?

A: All parts maintain ROHS3 compliance and EAR99 export classification. Substitute parts provide explicit operating temperature specifications (-40°C to 125°C), while the original part does not specify this parameter. This represents enhanced documentation rather than a functional difference.

Q: Can I use these connectors in applications requiring IP67K sealing?

A: Yes. All parts in this comparison, including the main part and all substitutes, feature IP67K sealing rating and are suitable for sealed connector applications.
