Molex 0334721311 Rectangular Connector Housing – Equivalent & Substitute Parts

Part Overview

The Molex 0334721311 is a 12-position receptacle housing for rectangular connectors, part of the MX150 33472 series. This component serves as the housing structure for female socket contacts in applications requiring sealed, in-line connector assemblies with a 0.138" (3.50mm) pitch configuration. The part is currently active in production with 820 units in stock.

Substitute parts are identified when design requirements permit alternative housing configurations while maintaining electrical and mechanical compatibility. Substitution becomes necessary when inventory constraints, lead time considerations, or application-specific material requirements necessitate alternative housing options within the same connector series.

Substitute Part Grouping Explanation

Substitute parts for the Molex 0334721311 are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Critical Parameters for Substitution:

• Connector type (Receptacle)
• Number of positions (12)
• Pitch specification (0.138" / 3.50mm)
• Row configuration (2 rows)
• Contact type (Female Socket)
• Mounting method (Free Hanging In-Line)
• Termination method (Crimp)
• Fastening mechanism (Latch Holder)
• Sealed feature requirement
• Series designation (MX150 33472)

Variable Parameters Permitted in Substitutes:

• Housing color
• Insulation material composition
• Operating temperature range
• Compliance certifications (RoHS, REACH)
• Moisture sensitivity level

The substitute part Molex 0334721311 maintains complete compatibility across all critical parameters while differing in housing color and material composition.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (0334721311): The Molex 0334721311 is the specified component when black housing color is a design requirement. This part is active in production with adequate inventory availability (820 units in stock).

Substitute Part Selection (0334721207): The Molex 0334721207 serves as a direct functional substitute when gray housing color is acceptable. This substitute provides additional compliance documentation including ROHS3 certification and REACH unaffected status. The substitute maintains all critical electrical and mechanical parameters while offering a documented operating temperature range of -40°C to 150°C. Inventory availability for the substitute is higher (4,771 units in stock), supporting extended lead time requirements.

Both parts are active products from Molex within the MX150 33472 series. Selection between these parts should be based on housing color requirements and compliance documentation needs for the end application.

Frequently Asked Questions (FAQ)

Q: Can the 0334721207 be used in place of the 0334721311?

A: Yes. The 0334721207 is a direct substitute for the 0334721311 across all critical electrical and mechanical parameters. Both housings accept identical 12-position, 3.50mm pitch contact sets and maintain the same mounting, termination, and fastening specifications. The primary difference is housing color (gray versus black).

Q: What is the difference between these two parts?

A: The parts differ in three areas: housing color (black for 0334721311, gray for 0334721207), insulation material composition (SPS glass-filled for 0334721311 versus PA/Nylon/SPS glass-filled for 0334721207), and compliance documentation (0334721207 provides ROHS3 and REACH status specifications). All connector interface specifications are identical.

Q: Are the contacts interchangeable between these housings?

A: Yes. Both housings are part of the same MX150 33472 series and accept the same crimp-terminated female socket contacts. Contacts are not included with either housing and must be sourced separately.

Q: Does housing color affect electrical performance?

A: No. Housing color is a cosmetic and identification feature only. Both black and gray housings provide identical sealed protection and electrical isolation characteristics.

Q: What is the pitch specification and why is it important?

A: The pitch is 0.138" (3.50mm), which defines the center-to-center spacing between contact positions. This specification is critical for mechanical compatibility with mating connector plugs and contact insertion tooling. Both substitute parts maintain this identical pitch.

Q: Can these housings be used in high-temperature applications?

A: The 0334721207 is documented for operation from -40°C to 150°C. The 0334721311 does not provide an operating temperature specification in available documentation. For applications requiring confirmed temperature ratings, the 0334721207 is the appropriate selection.

Q: What does "Sealed" mean for these connectors?

A: Sealed indicates that the housing design includes environmental protection features to prevent moisture and contaminant ingress into the contact cavity. Both parts provide this sealed protection.

Q: Are these parts RoHS compliant?

A: The 0334721207 is documented as ROHS3 compliant. The 0334721311 does not provide RoHS compliance documentation in available specifications. For applications requiring RoHS certification, the 0334721207 is the appropriate selection.
