TE Connectivity 776127-2 Rectangular Connector Plug Housing - Equivalent & Substitute Parts

Part Overview

The TE Connectivity 776127-2 is a 2-position rectangular connector plug housing from the Multi-Lock series. This component functions as a connector housing for crimp-terminated female socket contacts with a 0.138" (3.50mm) pitch. The part is currently Active in product status with 751 pieces in stock inventory.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector housings within the same series and pitch specification. Substitution becomes necessary when the primary part number is unavailable, when specific color coding requirements differ for application-specific circuit identification, or when alternative packaging formats are required for procurement workflows.

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 776127-2 are identified based on strict equivalence of the following critical parameters:

• Connector Type: Plug housing configuration
• Contact Type: Female socket accommodation
• Number of Positions: 2-position layout
• Pitch Specification: 0.138" (3.50mm) contact spacing
• Number of Rows: Single-row configuration
• Mounting Type: Free hanging in-line orientation
• Contact Termination: Crimp-style termination
• Fastening Type: Latch lock mechanism
• Insulation Material: Polybutylene Terephthalate (PBT)
• Operating Temperature Range: -30°C ~ 105°C
• Series Compatibility: Multi-Lock series

The substitute part 174463-7 maintains electrical and mechanical compatibility through identical specifications across all critical parameters. The primary distinction is the housing color (Yellow versus Black) and packaging format (Bulk versus standard), which do not affect functional interchangeability in applications where color coding is not a circuit-critical requirement.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 776127-2 and 174463-7 are Active product status components with full RoHS compliance and unlimited moisture sensitivity rating. Selection between these parts is determined by application-specific requirements:

Select 776127-2 when:

• Black housing color is required for circuit identification or application standards
• Standard packaging format aligns with procurement specifications
• Primary inventory availability is prioritized

Select 174463-7 when:

• Yellow housing color is required for circuit identification or application standards
• Bulk packaging format is compatible with assembly workflows
• Alternative inventory source is needed for supply chain continuity

Both parts maintain identical electrical performance, mechanical fit, and environmental operating specifications. The ROHS3 compliance of 776127-2 and RoHS compliance of 174463-7 are both acceptable for applications requiring lead-free construction. No functional performance difference exists between these parts when color coding is not a circuit-critical requirement.

Frequently Asked Questions (FAQ)

Q: Can 174463-7 be used as a direct replacement for 776127-2 in all applications?

A: The 174463-7 is electrically and mechanically equivalent to 776127-2 across all critical connector parameters including pitch, contact type, number of positions, and termination method. The primary difference is housing color (Yellow versus Black). Substitution is valid when color coding is not a circuit-critical requirement or when application standards do not mandate specific color identification.

Q: What is the significance of the different RoHS compliance levels (ROHS3 versus RoHS)?

A: Both ROHS3 Compliant and RoHS Compliant designations indicate lead-free construction and compliance with hazardous substance restrictions. ROHS3 represents the current regulatory standard. Both parts are acceptable for applications requiring RoHS-compliant components.

Q: Does the packaging difference (Standard versus Bulk) affect connector performance?

A: Packaging format does not affect electrical or mechanical performance. The difference is administrative and relates to procurement and assembly logistics. Standard packaging and Bulk packaging contain identical connector housings with identical specifications.

Q: Are the contacts included with these connector housings?

A: No. Both 776127-2 and 174463-7 are connector housings only. Contacts are not included and must be procured separately as specified for the Multi-Lock series 2-position configuration.

Q: What is the pitch specification and why is it critical for substitution?

A: Pitch is the center-to-center distance between contact positions, specified as 0.138" (3.50mm) for both parts. Pitch is a critical parameter for substitution because contacts and mating connectors are designed for specific pitch values. Both parts share identical pitch specifications, ensuring mechanical and electrical compatibility.

Q: Can these connector housings accommodate different contact types?

A: Both 776127-2 and 174463-7 are designed for Female Socket contact type with crimp termination. Contact compatibility is determined by the housing design and cannot be altered. Contacts must match the specified contact type and termination method.

Q: What is the operating temperature range and does it differ between the two parts?

A: Both parts operate across the identical temperature range of -30°C to 105°C. This specification is maintained across both the main part and substitute, ensuring thermal performance equivalence in all operating environments within this range.

Q: Is the Multi-Lock series designation important for substitution?

A: Yes. The Multi-Lock series designation indicates the connector family and fastening mechanism (Latch Lock). Both parts belong to the Multi-Lock series, ensuring compatibility with Multi-Lock series contacts and mating connectors. Parts from different series are not interchangeable.
