TE Connectivity AMP Connectors 3-1123722-8 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 3-1123722-8 is an 8-position rectangular connector housing designed for the Economy Power series. This plug housing accepts female socket contacts and is configured for crimp termination with latch lock fastening. The connector operates across a temperature range of -25°C to 105°C and is housed in blue polyamide (PA66) insulation material. This part is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained while offering alternative color options or improved inventory availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3-1123722-8 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain constant:

• Connector Type: Plug housing configuration
• Number of Positions: 8-position layout
• Pitch: 0.156" (3.96mm) contact spacing
• Contact Type: Female socket contacts
• Mounting Type: Free Hanging (In-Line) installation
• Contact Termination: Crimp connection method
• Fastening Type: Latch lock mechanism
• Insulation Material: Polyamide (PA66), Nylon 6/6
• Operating Temperature Range: -25°C ~ 105°C
• Series: Economy Power
• Product Status: Active
• RoHS Compliance: ROHS3 Compliant

The substitute part 1-1123722-8 maintains all of these parameters identically. The only variation is the housing color (Natural instead of Blue), which does not affect electrical or mechanical compatibility. Both parts share the same base product number (1123722) and are manufactured by TE Connectivity AMP Connectors.

Parameter Comparison

Engineering Selection Recommendations

Both the 3-1123722-8 and 1-1123722-8 are Active product status components manufactured by TE Connectivity AMP Connectors and maintain full ROHS3 compliance. Selection between these parts should be based on the following criteria:

3-1123722-8 (Blue Housing): Select this part when blue color coding is required for circuit identification, wiring harness organization, or system design specifications. Current inventory: 942 pieces.

1-1123722-8 (Natural Housing): Select this part when color coding is not a functional requirement or when natural color is preferred for aesthetic or organizational purposes. This substitute offers higher inventory availability with 1,900 pieces in stock. Both parts are electrically and mechanically interchangeable within the Economy Power series connector system.

Both parts maintain identical electrical performance, mechanical compatibility, temperature ratings, and compliance certifications. The choice between them is determined solely by color requirement and inventory availability.

Frequently Asked Questions (FAQ)

Q: Are the 3-1123722-8 and 1-1123722-8 electrically interchangeable?

A: Yes. Both parts maintain identical electrical specifications including connector type, number of positions, pitch, contact type, contact termination method, and operating temperature range. They are fully interchangeable from an electrical standpoint.

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

A: The housing color. The 3-1123722-8 features a blue housing, while the 1-1123722-8 features a natural (undyed) housing. All other mechanical and electrical parameters are identical.

Q: Can I use the 1-1123722-8 as a direct replacement for the 3-1123722-8 in my assembly?

A: Yes, provided that color coding is not a functional requirement in your application. If your design or assembly process requires blue color identification, the natural color substitute would not be appropriate.

Q: Do both parts require the same contact specifications?

A: Yes. Both housings are designed for the same female socket contacts with crimp termination. Contacts are not included with either housing and must be ordered separately.

Q: What is the pitch specification for these connectors?

A: Both parts feature a 0.156" (3.96mm) pitch, which defines the center-to-center spacing between contact positions in the 8-position layout.

Q: Are both parts RoHS compliant?

A: Yes. Both the 3-1123722-8 and 1-1123722-8 are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: What mounting configuration do these connectors support?

A: Both parts are configured for Free Hanging (In-Line) mounting, allowing installation directly onto cable assemblies or PCB-mounted mating connectors without additional mounting hardware.

Q: What is the operating temperature range for these connectors?

A: Both parts operate across a temperature range of -25°C to 105°C, suitable for industrial and commercial applications within this thermal envelope.
