HRP-03-S Equivalent & Substitute Parts

Part Overview

The HRP-03-S is a 3-position rectangular connector receptacle housing manufactured by JST Sales America Inc. This component is part of the HR series and is designed for free-hanging, in-line applications with crimp-type female socket contacts. The part is currently in active production status with robust inventory availability (561,141 pcs in stock). Finding equivalent or substitute parts may be necessary due to supply chain considerations, lead time requirements, or specific application constraints that favor alternative connector geometries or pitch specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector housings is determined by the following critical parameters:

• Connector Type & Contact Type: Both main and substitute parts must be receptacles with female socket contacts to maintain mating compatibility with corresponding plug assemblies.
• Number of Positions: The housing must accommodate the same number of contact positions (3 positions in this case).
• Number of Rows: Single-row configuration is required for direct substitution.
• Mounting Type: Free-hanging, in-line mounting must be preserved.
• Contact Termination: Crimp termination is the specified interface.
• Insulation Material & Color: Polyamide (PA66) construction with natural color ensures mechanical and environmental consistency.
• Compliance & Temperature Range: RoHS compliance and operating temperature specifications must be met or exceeded.

The substitute part 179228-3 (TE Connectivity AMP Connectors, CT series) meets these core substitution criteria. However, it operates at a different pitch specification (0.079" / 2.00mm versus 0.098" / 2.50mm), which represents a geometric variation that must be evaluated within the specific application context.

Parameter Comparison

Engineering Selection Recommendations

Both the HRP-03-S and 179228-3 are active-status products manufactured by established connector suppliers with full RoHS compliance and unlimited moisture sensitivity ratings. The primary distinction between these parts is the pitch specification: the HRP-03-S operates at 2.50mm pitch, while the 179228-3 operates at 2.00mm pitch. This geometric difference directly affects the physical dimensions and contact spacing of the housing.

Selection between these parts must be based on the pitch requirement of the application. The HRP-03-S is appropriate for systems designed around 2.50mm contact spacing, while the 179228-3 is suitable for applications requiring 2.00mm contact spacing. The 179228-3 provides an extended lower operating temperature limit (-55°C versus -25°C), which may be advantageous in applications requiring enhanced cold-temperature performance.

Both parts are suitable for applications requiring RoHS-compliant, crimp-terminated rectangular connectors with female socket contacts in a 3-position, single-row configuration.

Frequently Asked Questions (FAQ)

Q: Can the HRP-03-S and 179228-3 be used interchangeably in the same application?

A: Direct interchangeability depends on the pitch specification of the mating connector and PCB layout. The HRP-03-S uses 2.50mm pitch, while the 179228-3 uses 2.00mm pitch. These are not mechanically compatible with each other's mating connectors. Substitution is only valid if the application can accommodate the different pitch specification.

Q: What does pitch mean in connector specifications?

A: Pitch is the center-to-center distance between adjacent contact positions. For the HRP-03-S, this distance is 2.50mm (0.098 inches). For the 179228-3, this distance is 2.00mm (0.079 inches). Pitch directly determines the overall width and contact spacing of the connector housing.

Q: Are both parts RoHS compliant?

A: Yes, both the HRP-03-S and 179228-3 are RoHS compliant and carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: What is the difference in operating temperature ranges?

A: The HRP-03-S operates from -25°C to 85°C, while the 179228-3 operates from -55°C to 85°C. The 179228-3 provides a wider lower temperature range, making it suitable for applications requiring enhanced cold-temperature performance.

Q: Do these housings include contacts?

A: No, both the HRP-03-S and 179228-3 are housings only. Contacts must be sourced separately and crimped into the housing according to manufacturer specifications.

Q: What is the difference between the HR and CT series?

A: The HR series (HRP-03-S) is manufactured by JST Sales America Inc., while the CT series (179228-3) is manufactured by TE Connectivity AMP Connectors. These are distinct product lines from different manufacturers with different pitch specifications and design geometries.
