IPD1-03-S Equivalent & Substitute Parts

Part Overview

The IPD1-03-S is a 3-position rectangular connector receptacle housing manufactured by Samtec Inc. as part of the Mini Mate® IPD1 series. This connector is designed for free-hanging in-line applications with crimp contact termination and latch lock fastening. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, supply chain considerations, or application-specific requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IPD1-03-S are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 3 positions at 0.100" (2.54mm) spacing
• Mounting & Termination: Free-hanging in-line mounting with crimp termination
• Fastening Mechanism: Latch lock fastening system
• Compliance & Environmental Rating: ROHS3 compliance and MSL 1 rating

The substitute part 0050579703 (Molex SL 70066 series) meets all critical electrical and mechanical parameters required for direct substitution in applications requiring a 3-position, 2.54mm pitch rectangular connector receptacle with crimp termination and latch lock fastening.

Parameter Comparison

Engineering Selection Recommendations

Both the IPD1-03-S and 0050579703 are active production parts with ROHS3 compliance and MSL 1 ratings, qualifying them for equivalent use in applications requiring 3-position, 2.54mm pitch rectangular connector receptacles with crimp termination and latch lock fastening.

The primary differences are insulation material composition (Polyamide versus Polyester Glass Filled) and connector color (White versus Black). The Molex part includes specified operating temperature range (-40°C ~ 105°C), while the Samtec part does not provide this specification in the available data. Both parts are suitable for general rectangular connector applications where these parameters are not application-limiting factors.

Selection between these parts should be based on inventory availability, lead time requirements, and any application-specific constraints related to insulation material or color coding requirements.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0050579703 directly replace the Samtec IPD1-03-S?

A: Yes, the Molex part qualifies as a direct substitute based on matching electrical and mechanical parameters: 3-position receptacle, 0.100" (2.54mm) pitch, female socket contacts, crimp termination, latch lock fastening, and equivalent compliance ratings (ROHS3, MSL 1).

Q: What are the key differences between these two parts?

A: The primary differences are insulation material (Polyamide PA66 versus Polyester Glass Filled), connector color (White versus Black), and the availability of operating temperature specification (-40°C ~ 105°C for the Molex part). These differences do not affect the core electrical or mechanical compatibility for standard rectangular connector applications.

Q: Are there any compatibility concerns with the different insulation materials?

A: Both materials are standard for rectangular connector housings. The choice between Polyamide and Polyester Glass Filled depends on specific application requirements such as chemical resistance, mechanical strength, or thermal performance. Consult application requirements to determine if material selection is a limiting factor.

Q: Does the color difference (White vs. Black) affect functionality?

A: No. Color is a visual identifier only and does not affect electrical or mechanical performance. Selection should be based on application requirements for color coding or visual identification.

Q: Are both parts suitable for the same mounting and termination methods?

A: Yes. Both parts support free-hanging in-line mounting with crimp contact termination and latch lock fastening, ensuring compatibility with identical assembly and installation procedures.
