TE Connectivity 174923-6 Rectangular Connector Plug Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 174923-6 is a 6-position rectangular connector plug housing from the Multi-Lock series. This component is a gray polybutylene terephthalate (PBT) housing designed for crimp termination with female socket contacts in a free-hanging, in-line configuration. The part operates across a temperature range of -30°C to 105°C and features a 0.138" (3.50mm) pitch with latch holder fastening. The product maintains active status and RoHS compliance. Equivalent substitute parts are identified to provide alternative sourcing options when the primary gray housing variant is unavailable or when alternative color specifications are required for application-specific requirements.

Substitute Part Grouping Explanation

Substitute parts for the 174923-6 are identified based on strict parametric equivalence within the Multi-Lock rectangular connector series. The substitution criteria are limited to the following parameters that define functional interchangeability:

Critical Matching Parameters:

• Connector Type: Plug
• Contact Type: Female Socket
• Number of Positions: 6
• Pitch: 0.138" (3.50mm)
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Holder
• Insulation Material: Polybutylene Terephthalate (PBT)
• Operating Temperature Range: -30°C to 105°C
• Series: Multi-Lock

Variable Parameter:

• Color: Gray (174923-6), White (1-174923-1), Black (174923-2)

All substitute parts maintain identical electrical and mechanical specifications. Variations are limited to housing color, which does not affect functional performance or compatibility within the Multi-Lock connector ecosystem. All substitute parts share the same base product number (174923) and are derived from the same connector family.

Parameter Comparison

Engineering Selection Recommendations

All three parts—174923-6, 1-174923-1, and 174923-2—are functionally equivalent rectangular connector plug housings within the Multi-Lock series. Selection between these parts is determined by color specification requirements and compliance certifications.

174923-6 (Gray): Maintains RoHS Compliant status and is suitable for applications requiring standard RoHS compliance. Current inventory is 870 pieces.

1-174923-1 (White): Meets ROHS3 Compliant status, providing enhanced compliance for applications requiring the latest RoHS revision. Current inventory is 2670 pieces.

174923-2 (Black): Meets ROHS3 Compliant status, providing enhanced compliance for applications requiring the latest RoHS revision. Current inventory is 1252 pieces.

All parts are active products with unlimited moisture sensitivity tolerance (MSL 1) and operate identically across the -30°C to 105°C temperature range. Selection should be based on application color requirements and compliance specifications. The substitute parts maintain identical electrical and mechanical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Are the 174923-6, 1-174923-1, and 174923-2 interchangeable in terms of electrical and mechanical function?

A: Yes. All three parts are functionally 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. The only difference is housing color.

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

A: The primary difference is housing color: 174923-6 is gray, 1-174923-1 is white, and 174923-2 is black. Secondary differences include RoHS certification revision levels and REACH status documentation.

Q: Can I use a white (1-174923-1) or black (174923-2) housing in place of the gray (174923-6) housing?

A: Yes, provided your application does not have specific color requirements. All three housings are mechanically and electrically compatible within the Multi-Lock connector system.

Q: Do these parts require contacts to be functional?

A: Contacts are not included with any of these housing parts. Female socket contacts must be obtained separately and crimped into the housing according to TE Connectivity specifications.

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

A: The pitch is 0.138" (3.50mm), which defines the center-to-center spacing between connector positions. This specification must match the mating connector and contact specifications for proper assembly and electrical performance.

Q: Are all three parts RoHS compliant?

A: Yes. The 174923-6 is RoHS Compliant. The 1-174923-1 and 174923-2 are ROHS3 Compliant, representing compliance with the latest RoHS revision. All three meet RoHS requirements.

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

A: All three parts operate across -30°C to 105°C. This range applies to the PBT insulation material and the overall connector assembly.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates unlimited shelf life without special moisture control measures. These parts do not require desiccant packaging or controlled storage conditions.

Q: Can these housings be used in free-hanging applications?

A: Yes. The mounting type is specified as Free Hanging (In-Line), which means these housings are designed for applications where the connector is not mounted to a PCB or panel but remains suspended in-line within a cable or harness assembly.

Q: What is the fastening type, and how does it affect assembly?

A: The fastening type is Latch Holder, which means the connector uses a latching mechanism to secure mated connections. This provides positive retention and prevents accidental disconnection during operation.
