Engineering Selection Recommendations

All three substitute parts (0334724001, 0334724002, 0334724101) are functionally equivalent to the obsolete 0334720443 and are suitable for direct replacement in applications requiring a 4-position, 4.60mm pitch rectangular connector housing.

For gray housing applications: Part 0334724002 is the direct color match to the original 0334720443 and maintains active product status with ROHS3 compliance.

For black housing applications: Parts 0334724001 and 0334724101 provide equivalent functionality with active product status. Both are ROHS3 compliant.

All substitute parts carry active product status, ensuring long-term availability and supply chain stability compared to the obsolete original part. All substitutes maintain identical electrical performance, mechanical compatibility, and regulatory compliance (ROHS3, MSL 1).

Frequently Asked Questions (FAQ)

Q: Can I use part 0334724002 as a direct replacement for 0334720443?

A: Yes. Part 0334724002 is a parametric equivalent with identical specifications including 4-position count, 4.60mm pitch, sealed construction, and crimp termination. The only difference is product status (active vs. obsolete), which does not affect functional interchangeability.

Q: What is the difference between the black housing substitutes (0334724001 and 0334724101)?

A: Both parts are functionally identical with the same electrical and mechanical specifications. They differ only in inventory availability and packaging designation (both listed as Bulk). Either part is suitable for applications where black housing is acceptable.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts (0334724001, 0334724002, 0334724101) are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the compliance profile of the original 0334720443.

Q: Does color selection affect electrical performance?

A: No. Color variation (gray or black) is a cosmetic difference only and does not affect electrical performance, mechanical fit, or functional compatibility. Selection should be based on application requirements and design specifications.

Q: Why is the original part obsolete?

A: The 0334720443 is classified as obsolete, but all substitute parts maintain active product status within the same MX150 33472 series, ensuring continued availability and support for this connector housing specification.
