TE Connectivity 176276-4 Rectangular Connector Plug Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 176276-4 is a 9-position rectangular connector plug housing manufactured by TE Connectivity AMP Connectors. This component is classified as a rectangular connector housing designed for free-hanging, in-line applications with crimp contact termination. The part is currently active in production status with RoHS compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector interface, allowing direct functional replacement in applications where the primary part is unavailable or when alternative housing colors or series configurations are acceptable within system design constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 176276-4 are qualified based on strict equivalence of the following critical parameters:

Electrical and Mechanical Compatibility Parameters:

• Connector type (Plug)
• Contact type (Female Socket)
• Number of positions (9)
• Pitch spacing (0.156" / 3.96mm)
• Number of rows (3)
• Row spacing (0.181" / 4.60mm)
• Mounting configuration (Free Hanging, In-Line)
• Contact termination method (Crimp)
• Fastening mechanism (Latch Lock)
• Insulation material (Polyamide PA66, Nylon 6/6)
• Operating temperature range (-30°C ~ 105°C)

Acceptable Variation Parameters:

• Housing color (Yellow vs. Natural)
• Connector series designation (Universal Power vs. Power Double Lock)

The substitute parts 176276-1 and 177903-1 maintain all critical electrical and mechanical parameters while differing only in housing color and series classification. These differences do not affect physical or electrical compatibility with mating connectors or contact insertion/extraction functionality.

Parameter Comparison

Engineering Selection Recommendations

176276-1 Selection Criteria: The TE Connectivity 176276-1 is a direct parametric equivalent to the 176276-4, differing only in housing color (Natural vs. Yellow). Both parts share identical series designation (Universal Power), electrical specifications, mechanical dimensions, and compliance certifications. Selection of 176276-1 is appropriate when housing color is not a functional requirement or when yellow color identification is not mandated by system design specifications. Current inventory availability for 176276-1 is 3,151 pieces.

177903-1 Selection Criteria: The TE Connectivity 177903-1 maintains all critical electrical and mechanical parameters equivalent to the 176276-4 but operates under the Power Double Lock series designation rather than Universal Power. This part is suitable for applications where the Power Double Lock series configuration is compatible with the mating connector interface. Current inventory availability for 177903-1 is 2,736 pieces.

Compliance and Status: All three parts (176276-4, 176276-1, and 177903-1) maintain active production status, RoHS compliance, and MSL 1 rating. No compliance or regulatory restrictions differentiate these parts.

Frequently Asked Questions (FAQ)

Q: Can 176276-1 be used as a direct replacement for 176276-4?

A: Yes. The 176276-1 is electrically and mechanically equivalent to the 176276-4. The only difference is housing color (Natural vs. Yellow). If color coding is not a functional requirement in your application, 176276-1 provides complete compatibility with identical contact pitch, row spacing, position count, and termination specifications.

Q: What is the difference between the Universal Power series (176276-4, 176276-1) and the Power Double Lock series (177903-1)?

A: Both series maintain identical electrical and mechanical parameters for the 9-position, 3.96mm pitch connector housing. The series designation reflects internal design features of the connector family. The Power Double Lock series (177903-1) is compatible with applications using that series specification, while Universal Power series parts are compatible with their respective series interfaces.

Q: Are the contacts included with these connector housings?

A: No. All three parts (176276-4, 176276-1, and 177903-1) are connector housings only. Contacts must be sourced separately and inserted into the housing using crimp termination methods.

Q: What is the operating temperature range for these connector housings?

A: All three parts operate across the temperature range of -30°C to 105°C. This range is consistent across the Universal Power and Power Double Lock series.

Q: Are all three parts RoHS compliant?

A: Yes. The 176276-4, 176276-1, and 177903-1 are all RoHS compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the pitch spacing for these 9-position connectors?

A: The pitch is 0.156 inches (3.96mm) between contact positions. Row spacing is 0.181 inches (4.60mm) across the three rows of the 3-row configuration.

Q: Can I substitute 177903-1 for 176276-4 in any application?

A: Substitution of 177903-1 for 176276-4 is valid when the mating connector interface is compatible with the Power Double Lock series. Verify that your mating connector is specified for Power Double Lock series compatibility before substitution.
