TE Connectivity 3-1123722-9 Rectangular Connector Plug Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 3-1123722-9 is a 9-position rectangular connector plug housing from the Economy Power series. This component is a blue polyamide (PA66/Nylon 6/6) housing designed for crimp termination with latch lock fastening. The part operates across a temperature range of -25°C to 105°C and is RoHS compliant. This connector housing is actively manufactured and maintained in production inventory. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when specific color or compliance variants are required for system integration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 3-1123722-9 is determined by strict equivalence across the following critical parameters:

• Connector Type: Must be Plug
• Contact Type: Must be Female Socket
• Number of Positions: Must be 9
• Pitch: Must be 0.156" (3.96mm)
• Number of Rows: Must be 1
• Mounting Type: Must be Free Hanging (In-Line)
• Contact Termination: Must be Crimp
• Fastening Type: Must be Latch Lock
• Insulation Material: Must be Polyamide (PA66), Nylon 6/6
• Operating Temperature Range: Must be -25°C to 105°C
• Moisture Sensitivity Level: Must be 1 (Unlimited)

The identified substitute part 1-1123722-9 meets all critical electrical and mechanical parameters. The primary difference is the housing color (Natural versus Blue) and minor variations in regulatory compliance documentation. Both parts share the same base product number (1123722) and are manufactured by TE Connectivity AMP Connectors within the Economy Power series.

Parameter Comparison

Engineering Selection Recommendations

Both the 3-1123722-9 and 1-1123722-9 are active production parts manufactured by TE Connectivity AMP Connectors. Selection between these parts is based on the following criteria:

3-1123722-9 (Blue Housing): Select this part number when blue housing color is specified in system design documentation or when existing inventory uses blue connectors for visual identification purposes. This part carries RoHS compliance certification.

1-1123722-9 (Natural Housing): Select this part number when natural housing color is required or when the blue variant is unavailable. This part carries ROHS3 compliance certification and maintains significantly higher inventory availability (109,537 pieces versus 984 pieces). Both compliance certifications satisfy RoHS requirements for lead-free manufacturing.

Both parts are electrically and mechanically equivalent. The choice between them is determined by color specification and inventory availability. No functional performance difference exists between the two variants.

Frequently Asked Questions (FAQ)

Q: Are the 3-1123722-9 and 1-1123722-9 electrically interchangeable?

A: Yes. Both parts are electrically equivalent. They share identical specifications for connector type, contact type, number of positions, pitch, mounting type, contact termination, fastening type, insulation material, and operating temperature range.

Q: What is the only functional difference between these two part numbers?

A: The housing color differs. The 3-1123722-9 features a blue housing, while the 1-1123722-9 features a natural (unpigmented) housing. All electrical and mechanical parameters are identical.

Q: Can I use the natural housing variant in place of the blue housing variant?

A: Substitution is permissible when color specification is not a critical design requirement. If the system design or assembly documentation specifies blue housing for identification or aesthetic purposes, the natural variant is not suitable. If color is not specified as a functional requirement, the natural variant is a direct substitute.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both certifications indicate lead-free manufacturing compliance. ROHS3 represents an updated compliance standard. Both parts meet RoHS requirements. The difference in certification designation does not affect electrical or mechanical performance.

Q: Are contacts included with these connector housings?

A: No. Both part numbers are housings only. Contacts are not included and must be ordered separately. Ensure that selected contacts are compatible with 0.156" (3.96mm) pitch crimp termination specifications.

Q: What is the Moisture Sensitivity Level (MSL) rating?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts do not require special moisture control during storage, handling, or assembly.

Q: Can these connectors be used in applications requiring temperatures below -25°C or above 105°C?

A: No. Both parts are rated for operation between -25°C and 105°C. Applications requiring operation outside this temperature range require alternative connector housings with extended temperature specifications.
