TE Connectivity AMP Connectors 4-1123722-9 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 4-1123722-9 is a 9-position rectangular connector housing designed for the Economy Power series. This plug housing features a 0.156" (3.96mm) pitch and is configured as a free-hanging, in-line connector with crimp contact termination and latch lock fastening. The part is manufactured from polyamide (PA66) nylon 6/6 insulation material and is available in red color. This connector housing is classified as Active product status and is ROHS3 compliant. Substitute parts are necessary when specific color requirements, inventory availability, or operational temperature specifications differ from the primary part designation.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 4-1123722-9 connector housing is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Plug
• Contact Type: Female Socket
• Number of Positions: 9
• Pitch: 0.156" (3.96mm)
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Lock
• Insulation Material: Polyamide (PA66), Nylon 6/6
• Series: Economy Power
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameters (Non-Critical for Substitution):

• Color: Red (main part) vs. Natural (substitute)
• Operating Temperature: Not specified (main part) vs. -25°C ~ 105°C (substitute)

The substitute part 1-1123722-9 maintains full electrical and mechanical compatibility with the 4-1123722-9 through identical positioning, pitch, termination method, and fastening mechanism. The primary differences are cosmetic (color) and environmental specification documentation.

Parameter Comparison

Engineering Selection Recommendations

Both the 4-1123722-9 and 1-1123722-9 are Active product status components manufactured by TE Connectivity AMP Connectors and maintain full ROHS3 compliance with MSL 1 (Unlimited) moisture sensitivity rating. Selection between these parts is based on the following criteria:

Select 4-1123722-9 when:

• Red color housing is required for circuit board identification, wiring harness organization, or system design specifications
• Existing inventory or supply chain documentation specifies the red variant

Select 1-1123722-9 when:

• Natural color housing is acceptable or preferred for aesthetic or design purposes
• Operating temperature range documentation (-25°C ~ 105°C) is required for compliance verification
• Higher inventory availability is prioritized (109,537 pcs vs. 917 pcs)
• Cost optimization through substitute part selection is a procurement objective

Both parts are electrically and mechanically interchangeable within the Economy Power series connector system. The choice between them does not affect circuit functionality, signal integrity, or mechanical fit within the connector interface.

Frequently Asked Questions (FAQ)

Q: Are the 4-1123722-9 and 1-1123722-9 electrically interchangeable?

A: Yes. Both parts are 9-position plug housings with identical electrical specifications, including female socket contact type, 0.156" (3.96mm) pitch, crimp termination, and latch lock fastening. They function identically within the Economy Power series connector system.

Q: What is the primary difference between these two parts?

A: The main difference is color: the 4-1123722-9 is red, while the 1-1123722-9 is natural. The 1-1123722-9 also includes documented operating temperature range (-25°C ~ 105°C), whereas the 4-1123722-9 does not specify this parameter.

Q: Can I use the natural-colored 1-1123722-9 in place of the red 4-1123722-9?

A: Yes, from an electrical and mechanical standpoint. However, if red color is specified in your design documentation, assembly procedures, or quality control requirements, the natural variant may not meet those specifications. Verify color requirements in your system design before substitution.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the 4-1123722-9 and 1-1123722-9 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, making them suitable for equivalent use in compliant applications.

Q: Which part should I select for new designs?

A: Selection depends on your specific requirements. If color identification is not critical and higher inventory availability is beneficial, the 1-1123722-9 is suitable. If red color is specified or required for your application, use the 4-1123722-9. Both are Active status products with equivalent reliability and performance.

Q: Do these housings include contacts?

A: No. Both the 4-1123722-9 and 1-1123722-9 are connector housings only. Contacts must be procured separately and installed via crimp termination.

Q: What is the pitch specification, and why does it matter?

A: Both parts have a 0.156" (3.96mm) pitch, which defines the center-to-center spacing between contact positions. This specification must match your mating connector and contact set to ensure proper alignment and electrical connection.
