Substitute Part Grouping Explanation

Substitute parts for the Molex 0334720445 are determined by strict equivalence across the following critical parameters:

Connector type (Receptacle)
Contact type (Female Socket)
Number of positions (4)
Pitch specification (0.138" / 4.60mm)
Number of rows (2)
Mounting configuration (Free Hanging In-Line)
Contact termination method (Crimp)
Fastening type (Latch Holder)
Sealed feature requirement
Series compatibility (MX150 33472)
Base product number (033472)

All three substitute parts meet these criteria. Variations exist only in color (Gray vs. Black) and product status (Active vs. Obsolete), which do not affect electrical or mechanical compatibility. The substitute parts are all active production items with enhanced availability compared to the obsolete main part.

Engineering Selection Recommendations

All three substitute parts (0334724001, 0334724002, 0334724101) are direct functional equivalents to the obsolete Molex 0334720445. Selection among these active production alternatives should be based on the following criteria:

Color Requirement: If the application specifies gray housing, select either 0334720445 (if legacy stock is available) or 0334724002 (active production equivalent). If black housing is acceptable, 0334724001 or 0334724101 are suitable alternatives.

Availability and Lead Time: All substitute parts carry ROHS3 compliance and MSL 1 rating. The substitute parts offer significantly higher inventory levels (44,337 pcs for 0334724001, 6,308 pcs for 0334724002, and 1,982 pcs for 0334724101) compared to the obsolete main part (686 pcs), ensuring reliable supply chain continuity.

Compliance Status: All substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for new designs and production.

Frequently Asked Questions (FAQ)

Q: Can I use 0334724001 or 0334724101 (black) as a direct replacement for 0334720445 (gray)?

A: Yes, from an electrical and mechanical standpoint, the black variants are fully compatible. The color difference does not affect connector function, mating characteristics, or electrical performance. Selection should be based on application requirements and visual identification needs.

Q: What is the difference between 0334724001 and 0334724101?

A: Both parts are black 4-position receptacles with identical electrical and mechanical specifications. The difference lies in inventory availability (0334724001: 44,337 pcs vs. 0334724101: 1,982 pcs) and packaging designation (both Bulk). Either part meets the functional requirements for substitution.

Q: Why is 0334720445 listed as obsolete?

A: The main part is obsolete, but active production equivalents are available. The substitute parts (0334724001, 0334724002, 0334724101) are all active production items within the same MX150 33472 series, ensuring continued availability for new designs and production runs.

Q: Are the operating temperature specifications the same across all parts?

A: The substitute parts specify an operating temperature range of -40°C to 150°C. The main part does not include this specification in the provided data. The substitute parts' temperature rating applies to the housing and insulation materials and should be verified against application requirements.

Q: Do all parts require separate contact procurement?

A: Yes. All parts in this comparison carry the note "Contacts Not Included." Crimp contacts must be sourced separately and must be compatible with the 4.60mm pitch and female socket configuration.

Q: Are there any packaging differences I should consider?

A: The main part (0334720445) is listed with unspecified packaging, while all substitute parts are supplied in Bulk packaging. Confirm bulk packaging specifications with your supplier if specific packaging requirements exist.
