Substitute Part Grouping Explanation

Substitute parts for the 78211-009LF are identified based on strict alignment of the following critical parameters:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 9
• Pitch: 0.100" (2.54mm)
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Color: Black
• Features: Polarizing Key
• Moisture Sensitivity Level: 1 (Unlimited)

The Molex 0901230109 meets all these criteria, establishing it as a parametric equivalent. Both parts share identical functional and mechanical specifications within the rectangular connector housing category, differing only in insulation material composition and operating temperature range extensions.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol ICC 78211-009LF and Molex 0901230109 are Active status products with full RoHS compliance certifications. The 78211-009LF carries RoHS Compliant status, while the 0901230109 carries ROHS3 Compliant status, indicating both meet current regulatory requirements. The Molex substitute provides an extended lower operating temperature limit of -55°C compared to the Amphenol part's -40°C minimum, offering broader thermal operating range capability. Selection between these parts should be based on design temperature requirements, supply chain availability, and existing connector ecosystem compatibility within the application.

Frequently Asked Questions (FAQ)

Q: What makes the Molex 0901230109 a valid substitute for the Amphenol ICC 78211-009LF?

A: Both parts share identical electrical and mechanical specifications: 9-position receptacle housings with 0.100" pitch, female socket contacts, crimp termination, polarizing key features, and MSL 1 rating. They are functionally interchangeable in applications designed for either connector type.

Q: Are there differences in insulation material between these parts?

A: Yes. The 78211-009LF uses Polyphenylene Modified insulation, while the 0901230109 uses Polyphenylene Oxide (PPO). Both materials are suitable for the specified operating temperature ranges and environmental conditions.

Q: Does the extended temperature range of the Molex part affect compatibility?

A: No. The Molex 0901230109 operates from -55°C to 105°C, which encompasses the Amphenol part's -40°C to 105°C range. The extended lower temperature capability does not create incompatibility; it provides additional operational margin.

Q: Are contacts included with these connector housings?

A: No. Both the 78211-009LF and 0901230109 are housings only. Contacts must be sourced separately and are not included with these parts.

Q: What is the significance of the polarizing key feature?

A: The polarizing key prevents incorrect mating orientation, ensuring proper connector alignment during assembly. Both substitute parts include this feature, maintaining design safety and reliability.

Q: How do the RoHS compliance statuses differ?

A: The 78211-009LF is RoHS Compliant, while the 0901230109 is ROHS3 Compliant. Both meet current regulatory requirements; ROHS3 represents the current standard revision with updated substance restrictions.
