TE Connectivity AMP Connectors 177534-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 177534-4 is a 4-position rectangular receptacle connector designed for IDC (Insulation Displacement Contact) termination with discrete wire gauges from 24-28 AWG. This connector operates as a female socket in a single-row configuration with 0.098" (2.50mm) pitch spacing and free-hanging in-line mounting. The part is currently active in production with 759 units in stock. Alternative equivalent parts may be required due to supply chain considerations, inventory availability, or specific application requirements where substitute connectors meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 177534-4 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Receptacle
• Contact type: Female socket
• Number of positions: 4
• Pitch spacing: 0.098" (2.50mm)
• Number of rows: 1
• Cable termination method: IDC
• Contact finish: Tin
• Mounting type: Free hanging (in-line)
• Color: Black
• Moisture sensitivity level: 1 (Unlimited)

Wire Gauge Compatibility: The main part accepts 24-28 AWG wire. Substitute parts must support the wire gauge range required for the application. A substitute supporting 24 AWG operates within the main part's range and is therefore compatible for applications using 24 AWG conductors.

The JST Sales America Inc. 04HR-4K-P-N< meets all mandatory matching parameters and supports 24 AWG wire gauge, establishing it as a valid equivalent for applications utilizing 24 AWG discrete wires.

Engineering Selection Recommendations

TE Connectivity 177534-4 (Primary Part)

The TE Connectivity 177534-4 remains the primary selection for applications requiring 24-28 AWG wire gauge compatibility. This part is active in production with established supply availability (759 units in stock). The part carries an "Not applicable" RoHS status designation.

JST Sales America Inc. 04HR-4K-P-N< (Equivalent Substitute)

The JST 04HR-4K-P-N< serves as a functional equivalent for applications utilizing 24 AWG discrete wire. This part is active in production with higher inventory availability (1,675 units in stock). The JST connector includes a detent lock fastening feature and carries ROHS3 compliance certification. Selection of this substitute is appropriate when 24 AWG wire gauge meets application requirements and ROHS3 compliance is mandated by design or regulatory specifications.

Both connectors share identical electrical and mechanical interface characteristics: 4-position receptacle configuration, 0.098" (2.50mm) pitch, IDC termination, tin contact finish, and free-hanging in-line mounting in black color.

Frequently Asked Questions (FAQ)

Q: Can the JST 04HR-4K-P-N< replace the TE Connectivity 177534-4 in all applications?

A: The JST 04HR-4K-P-N< is compatible with applications using 24 AWG wire. If the application requires 25, 26, 27, or 28 AWG wire support, the TE Connectivity 177534-4 must be used, as it supports the full 24-28 AWG range while the JST part supports only 24 AWG.

Q: What is the significance of the detent lock feature on the JST connector?

A: The JST 04HR-4K-P-N< includes a detent lock fastening mechanism. This feature provides mechanical retention during mating operations. The TE Connectivity 177534-4 does not specify a fastening type, indicating a different mechanical interface design. Verify mating connector compatibility before substitution.

Q: Are there compliance differences between these two parts?

A: The JST 04HR-4K-P-N< carries ROHS3 compliance certification. The TE Connectivity 177534-4 lists RoHS status as "Not applicable." If ROHS3 compliance is required by design specifications or regulatory requirements, the JST part satisfies this requirement.

Q: Do both connectors use the same IDC termination process?

A: Both connectors employ IDC (Insulation Displacement Contact) cable termination. IDC termination is compatible between these parts for discrete wire applications. Verify that the wire gauge of your application falls within the supported range of your selected connector.

Q: What is the pitch spacing, and why does it matter?

A: Both connectors operate at 0.098" (2.50mm) pitch spacing. This pitch dimension determines physical compatibility with mating connectors and PCB layouts. Identical pitch ensures mechanical interchangeability in the connector interface.

Q: Can these connectors be used interchangeably in existing designs?

A: Interchangeability depends on wire gauge requirements and mating connector specifications. Verify that the mating connector is compatible with the substitute part's fastening type (detent lock on JST versus unspecified on TE Connectivity) and that your wire gauge falls within the supported range of the selected connector.
