TE Connectivity 5-1123722-9 Rectangular Connector Plug Housing - Equivalent & Substitute Parts

Part Overview

The TE Connectivity 5-1123722-9 is a 9-position rectangular connector plug housing designed for the Economy Power series. This component serves as the housing structure for crimp-terminated female socket contacts in free-hanging, in-line applications. The part is manufactured from polyamide (PA66) nylon 6/6 material and operates across a temperature range of -25°C to 105°C. The connector features a 0.156" (3.96mm) pitch configuration with latch lock fastening. This part is currently active in production with RoHS compliance certification. Equivalent substitute parts may be required due to color availability, inventory considerations, or specific application requirements while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 5-1123722-9 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
• Operating Temperature Range: -25°C to 105°C
• Series: Economy Power
• Manufacturer: TE Connectivity AMP Connectors

Variable Parameters (Non-Critical for Substitution):

• Color (Black vs. Natural)
• RoHS Certification Version (RoHS vs. ROHS3)
• HTSUS Classification

The substitute part 1-1123722-9 maintains complete electrical and mechanical compatibility with the main part number 5-1123722-9 through identical specifications across all critical parameters. The primary difference is the housing color (Natural vs. Black) and RoHS certification level, neither of which affects functional performance or interchangeability in the connector system.

Parameter Comparison

Engineering Selection Recommendations

Both the 5-1123722-9 and 1-1123722-9 are active production parts manufactured by TE Connectivity AMP Connectors with full RoHS compliance certification. The parts are functionally and mechanically interchangeable for all applications requiring a 9-position rectangular connector plug housing with 0.156" pitch, crimp termination, and latch lock fastening.

Selection Criteria:

The 5-1123722-9 (Black housing) is appropriate for applications where color specification is a design requirement or where visual identification of connector type is necessary.

The 1-1123722-9 (Natural housing) is appropriate for applications where color is not a functional requirement and offers significantly higher inventory availability (109,537 units vs. 998 units).

Both parts maintain identical electrical performance, mechanical durability, and environmental operating specifications across the -25°C to 105°C temperature range. The ROHS3 certification of the substitute part 1-1123722-9 represents a more current compliance standard than the RoHS certification of the main part 5-1123722-9, with no functional impact on component performance.

Frequently Asked Questions (FAQ)

Q: Are the 5-1123722-9 and 1-1123722-9 electrically interchangeable?

A: Yes. Both parts are identical in electrical specifications, contact configuration, pitch, and termination method. They function identically in circuit applications.

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

A: The housing color differs: 5-1123722-9 features a black housing, while 1-1123722-9 features a natural (undyed) housing. This is a cosmetic difference with no impact on electrical or mechanical performance.

Q: Can I substitute the natural housing part for the black housing part in my design?

A: Substitution is possible if color specification is not a design requirement. If the design documentation specifies black housing for identification or aesthetic purposes, the natural housing variant would not meet those requirements.

Q: What does the difference in RoHS certification levels mean?

A: The 5-1123722-9 carries RoHS compliance certification, while the 1-1123722-9 carries ROHS3 compliance certification. ROHS3 represents a more recent version of the RoHS directive. Both certifications confirm the parts are free from restricted substances. The ROHS3 certification of the substitute part meets or exceeds the compliance requirements of the original part.

Q: Are there any temperature or environmental performance differences?

A: No. Both parts operate identically across the -25°C to 105°C temperature range and maintain the same Moisture Sensitivity Level (MSL 1 - Unlimited).

Q: What is the pitch specification and why is it important?

A: Both parts feature a 0.156" (3.96mm) pitch, which defines the center-to-center spacing between contact positions. This specification must match the mating connector and PCB layout. Both parts are identical in this critical parameter.

Q: Can these connectors be used with different contact types?

A: No. Both parts are designed specifically for female socket contacts with crimp termination. The housing configuration is not compatible with other contact types or termination methods.

Q: What mounting configuration do these connectors support?

A: Both parts are configured for free-hanging, in-line mounting, meaning they are not panel-mounted or PCB-mounted. They connect two cable assemblies or wire harnesses directly.

Q: Is there a difference in fastening mechanism between the two parts?

A: No. Both parts utilize latch lock fastening, providing positive mechanical connection and retention between mating plug and receptacle connectors.
