TE Connectivity 2-1123722-9 Rectangular Connector Plug Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 2-1123722-9 is a 9-position rectangular connector plug housing from the Economy Power series. This component is a yellow polyamide (PA66/Nylon 6/6) housing designed for crimp-terminated female socket contacts with a 0.156" (3.96mm) pitch. The part is actively manufactured and RoHS3 compliant, operating across a temperature range of -25°C to 105°C. Substitute parts are identified when equivalent electrical and mechanical specifications are maintained across all critical parameters, enabling direct replacement in applications where housing color variation is acceptable.

Substitute Part Grouping Explanation

Substitution of rectangular connector plug housings is determined by strict equivalence across electrical and mechanical parameters. The following criteria establish substitutability for the 2-1123722-9:

Critical Parameters for Substitution:

• Connector type (Plug)
• Contact type (Female Socket)
• Number of positions (9)
• Pitch specification (0.156" / 3.96mm)
• Number of rows (1)
• Mounting type (Free Hanging In-Line)
• Contact termination method (Crimp)
• Fastening mechanism (Latch Lock)
• Insulation material (Polyamide PA66/Nylon 6/6)
• Operating temperature range (-25°C to 105°C)
• RoHS compliance status (ROHS3)
• Moisture sensitivity level (MSL 1)

The substitute part 1-1123722-9 maintains identical specifications across all critical electrical and mechanical parameters. The only variation is housing color (Natural versus Yellow), which does not affect functional performance or compatibility in applications where color differentiation is not a design requirement.

Parameter Comparison

Engineering Selection Recommendations

Both the 2-1123722-9 and 1-1123722-9 are active products manufactured by TE Connectivity and maintain full ROHS3 compliance. Selection between these parts is based on application-specific requirements:

2-1123722-9 (Yellow Housing): Select this part when housing color coding is required for circuit identification, wiring harness organization, or visual assembly verification protocols.

1-1123722-9 (Natural Housing): Select this part when housing color is not a functional requirement. This substitute offers significantly higher inventory availability (109,537 pieces versus 1,067 pieces), reducing lead times and supply chain risk for high-volume production or rapid deployment scenarios.

Both parts share identical electrical performance, mechanical compatibility, and regulatory compliance. The choice between them depends solely on whether housing color differentiation is specified in the application design or assembly documentation.

Frequently Asked Questions (FAQ)

Q: Can the 1-1123722-9 (Natural) be used as a direct replacement for the 2-1123722-9 (Yellow)?

A: Yes. Both parts are electrically and mechanically identical. The only difference is housing color. Direct substitution is valid when color coding is not a functional requirement in the application.

Q: Are there any electrical performance differences between the yellow and natural housing versions?

A: No. Both housings are manufactured from identical Polyamide (PA66/Nylon 6/6) material with equivalent electrical properties, operating temperature ranges, and contact performance specifications.

Q: Do both parts accept the same crimp contacts?

A: Yes. Both the 2-1123722-9 and 1-1123722-9 are designed for identical crimp-terminated female socket contacts with 0.156" (3.96mm) pitch. Contact compatibility is determined by housing position count and pitch, which are identical across both parts.

Q: What is the significance of the different HTSUS codes between these parts?

A: The HTSUS codes (8536.69.8000 for the yellow version and 8538.90.6000 for the natural version) reflect tariff classification differences based on housing color. This does not affect technical compatibility or performance.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the 2-1123722-9 and 1-1123722-9 carry ROHS3 compliance certification and are suitable for applications requiring RoHS compliance.

Q: What does Moisture Sensitivity Level 1 mean?

A: MSL 1 indicates unlimited shelf life without moisture control requirements. Both parts can be stored and handled without special desiccant packaging or humidity-controlled environments.

Q: Can these housings be used interchangeably in existing connector assemblies?

A: Yes, provided the assembly design does not specify housing color as a functional or identification requirement. The mechanical interface, contact retention, and latch lock mechanism are identical.
