Engineering Selection Recommendations

Primary Recommendation: Molex 0334724001

The 0334724001 is designated as the manufacturer-recommended substitute. This part maintains full electrical and mechanical compatibility with the obsolete 0334720402 while offering active product status and documented operating temperature range (-40°C to 150°C). Selection of this part ensures long-term supply availability and compliance with current manufacturing standards.

Secondary Options: Molex 0334724002 and 0334724101

Both parts are parametric equivalents with identical electrical and mechanical specifications. The 0334724002 matches the original gray color, while the 0334724101 provides a black alternative. Both are active products with ROHS3 compliance and MSL 1 rating. Selection between these options depends on color requirements for your specific application.

All three substitute parts are functionally interchangeable with the original 0334720402 for connector housing applications within the MX150 33472 series.

Frequently Asked Questions (FAQ)

Q: Can I use the substitute parts as direct replacements for the 0334720402?

A: Yes. All substitute parts (0334724001, 0334724002, 0334724101) maintain identical electrical and mechanical interfaces. They are functionally interchangeable for connector housing applications.

Q: What is the difference between the substitute parts?

A: The primary differences are color and inventory availability. The 0334724001 and 0334724101 are black housings, while the 0334724002 is gray. All three share identical electrical specifications, pitch, position count, and mounting characteristics.

Q: Why is the original 0334720402 listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. The manufacturer recommends transitioning to active alternatives to ensure continued supply chain access and support.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts carry ROHS3 compliance certification, matching the original part's environmental standards.

Q: Does color selection affect connector performance?

A: No. Color is a cosmetic parameter only and does not affect electrical or mechanical performance. Selection should be based on application requirements and design specifications.

Q: What is the operating temperature range for these connectors?

A: The substitute parts are rated for -40°C to 150°C operation. This specification is documented for the active alternatives but was not specified for the obsolete original part.
