IPD1-03-S-R Equivalent & Substitute Parts

Part Overview

The IPD1-03-S-R is a 3-position rectangular connector receptacle housing manufactured by Samtec Inc. as part of the Mini Mate® IPD1 series. This connector operates at a 0.100" (2.54mm) pitch and features a single-row configuration with crimp termination and latch lock fastening. The part is actively produced and ROHS3 compliant, making it suitable for applications requiring standard rectangular connectivity in compact form factors. Substitute parts may be required due to inventory constraints, supply chain considerations, or design flexibility across compatible connector families.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IPD1-03-S-R are determined by strict equivalence across the following critical parameters:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 3
• Pitch: 0.100" (2.54mm)
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Lock
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The Molex 0050579703 meets all these criteria and qualifies as a parametric equivalent. Differences in insulation material (Polyester, Glass Filled vs. Polyamide) and housing color (Black vs. White) do not affect functional interchangeability for the specified connector interface.

Parameter Comparison

Engineering Selection Recommendations

Both the IPD1-03-S-R and 0050579703 are active products with ROHS3 compliance and MSL 1 ratings, confirming their suitability for current production and long-term availability. The Molex 0050579703 provides an additional specification advantage with a defined operating temperature range of -40°C to 105°C, which may be beneficial for applications with known thermal requirements. The difference in insulation material composition does not affect the electrical or mechanical interface compatibility. Housing color variation is a cosmetic distinction and does not impact functional performance. Selection between these parts should be based on inventory availability, cost considerations, and any specific thermal or material requirements of the end application.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical electrical and mechanical specifications across all critical parameters: 3-position receptacle, 0.100" pitch, female socket contacts, crimp termination, and latch lock fastening. They are functionally interchangeable at the connector interface level.

Q: Does the difference in insulation material affect compatibility?

A: No. The insulation material difference (Polyamide vs. Polyester, Glass Filled) does not affect the connector's electrical or mechanical interface. Both materials meet the same RoHS3 and MSL 1 requirements.

Q: Why is the housing color different?

A: Housing color is a cosmetic feature and does not impact electrical or mechanical performance. Selection between white and black housings is based on application aesthetics or internal design standards only.

Q: What does the operating temperature specification mean for the Molex part?

A: The Molex 0050579703 specifies an operating temperature range of -40°C to 105°C. This defines the thermal limits within which the connector maintains its specified electrical and mechanical properties. The Samtec part does not provide an operating temperature specification in the available data.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the IPD1-03-S-R and 0050579703 are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, confirming their suitability for modern manufacturing and long-term storage without special handling.

Q: Do these parts include contacts?

A: No. Both the Samtec IPD1-03-S-R and Molex 0050579703 are connector housings only. Contacts must be sourced separately and crimped into the housing according to the manufacturer's specifications.
