Molex 0903310001 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0903310001 is a 6-position rectangular connector receptacle housing with 0.156" (3.96mm) pitch, designed for free-hanging in-line applications with crimp contact termination and latch lock fastening. This part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and procurement planning. The receptacle housing requires separate contact procurement and assembly.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0903310001 receptacle housing is determined by strict alignment of the following electrical and mechanical parameters:

• Connector pitch: 0.156" (3.96mm) — determines physical mating compatibility
• Number of positions: 6 — defines contact count and housing size
• Number of rows: 1 — specifies single-row configuration
• Mounting type: Free Hanging (In-Line) — ensures installation method compatibility
• Contact termination: Crimp — maintains assembly process compatibility
• Fastening type: Latch Lock — ensures mechanical retention method compatibility

The identified substitute part TE Connectivity AMP Connectors 1-1123722-6 meets all these criteria. However, this part is a plug housing (male connector type) rather than a receptacle (female connector type). This represents a complementary pairing relationship rather than a direct one-to-one substitution. The plug housing is used in mated pairs with receptacle housings in complete connector assemblies.

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 1-1123722-6 is the identified equivalent for the obsolete Molex 0903310001 based on matching electrical and mechanical specifications. Key selection factors:

• Product Status: The substitute part maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete Molex part.
• Compliance: Both parts meet RoHS requirements. The substitute part carries RoHS Compliant status while the original is ROHS3 Compliant, both acceptable for modern applications.
• Moisture Sensitivity: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.
• Connector Pairing: The plug housing (1-1123722-6) is designed to mate with compatible receptacle housings. For complete connector assembly replacement, both receptacle and plug housings must be sourced from compatible series.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-1123722-6 directly replace the Molex 0903310001?

A: No. The TE part is a plug housing while the Molex part is a receptacle housing. These are complementary connector types designed to mate together. Direct replacement requires identifying the corresponding receptacle housing from the TE Connectivity Economy Power series with matching pitch (0.156"), position count (6), and fastening type (latch lock).

Q: What does "contacts not included" mean for these housings?

A: Both housings are supplied without pre-installed contacts. Contacts must be procured separately and crimped into the housing during assembly. Contact selection must match the housing pitch and termination method (crimp).

Q: Are these parts interchangeable in terms of pitch and position count?

A: Yes, both parts share identical pitch (0.156" / 3.96mm), position count (6), row configuration (1 row), and mounting type (free hanging in-line). These parameters determine physical and electrical compatibility within the connector system.

Q: What is the significance of the latch lock fastening type?

A: Latch lock fastening provides mechanical retention between mated plug and receptacle housings. Both parts incorporate this fastening mechanism, ensuring consistent mating force and connection reliability.

Q: Why is the Molex part listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The TE Connectivity equivalent maintains active production status, making it the recommended choice for new designs and ongoing system support.
