Engineering Selection Recommendations

All three substitute parts (0334724001, 0334724002, 0334724101) are functionally equivalent to the obsolete 0334720407 and are suitable for direct replacement in applications requiring 4-position rectangular connector housings with 4.60mm pitch.

Active Product Status: All substitute parts maintain active product status with Molex, ensuring ongoing availability and supply chain continuity compared to the obsolete main part.

Compliance & Certifications: All substitute parts are ROHS3 compliant and carry MSL rating 1 (unlimited moisture sensitivity), matching the environmental and regulatory requirements of the original part.

Color Selection: Part 0334724002 maintains gray color matching the original 0334720407. Parts 0334724001 and 0334724101 are black variants. Color selection should be based on application requirements and existing assembly standards.

Inventory Availability: Part 0334724002 (gray, 6,308 units) provides color continuity with moderate stock levels. Part 0334724001 (black, 44,337 units) offers maximum availability. Part 0334724101 (black, 1,982 units) provides alternative black option with lower stock.

Frequently Asked Questions (FAQ)

Q: Can I use part 0334724001 or 0334724101 (black) as a direct replacement for 0334720407 (gray)?

A: Yes. The black variants are electrically and mechanically equivalent. Color differences do not affect connector function, mating capability, or electrical performance. Selection should be based on application aesthetics or assembly standards.

Q: Are all substitute parts compatible with the same contact pins and mating connectors?

A: Yes. All parts share identical pitch (4.60mm), position count (4), row configuration (2), and fastening mechanism (latch holder). They accept the same crimp contacts and mate with identical plug connectors.

Q: What is the difference between the substitute parts?

A: The three substitute parts differ only in color (gray vs. black) and current inventory levels. All other electrical, mechanical, and environmental specifications are identical.

Q: Why is the original part 0334720407 obsolete?

A: The part is classified as obsolete by Molex. The active substitute parts (0334724001, 0334724002, 0334724101) represent the current production alternatives within the MX150 33472 series.

Q: Do I need to change my assembly process to use a substitute part?

A: No. All substitute parts maintain identical mounting type (free-hanging in-line), termination method (crimp), and fastening mechanism (latch holder), requiring no changes to assembly procedures or tooling.

Q: Are there any temperature or environmental rating differences?

A: The substitute parts specify operating temperature range of -40°C to 150°C. The original part does not list this specification. All parts maintain MSL rating 1 (unlimited) and ROHS3 compliance.
