TE Connectivity AMP Connectors 1-103688-7 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1-103688-7 is an 18-position rectangular connector receptacle housing designed for 0.100" (2.54mm) pitch applications. This component functions as a female socket receptacle for crimp-terminated contacts in free-hanging inline configurations. The part is Active in product status and RoHS3 Compliant, making it suitable for current production and regulated applications. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, design flexibility, or application-specific requirements.

Engineering Selection Recommendations

All four rectangular connector receptacles listed maintain Active product status and comply with RoHS regulations, confirming suitability for current production environments. Selection among these parts should be based on the following engineering criteria:

Primary Selection (1-103688-7): Use the original TE Connectivity part when design specifications explicitly require the AMPMODU MTE series, thermoplastic insulation material, or the extended lower operating temperature limit of -65°C.

Secondary Selection (0050579318): The Molex SL 70066 series part provides equivalent functionality with polyester glass-filled insulation and maintains ROHS3 compliance. This part is suitable when Molex component standardization is preferred and operating temperatures remain within -40°C to 105°C.

Secondary Selection (65039-019LF): The Amphenol ICC Mini-PV™ Basics+ series part offers the highest inventory availability (1555 pcs) and is suitable for applications where REACH-affected component status is acceptable. Operating temperature range of -40°C to 105°C is maintained.

Secondary Selection (65240-018LF): The Amphenol ICC DUBOX™/MezzSelect™ part provides the widest operating temperature range (-65°C to 125°C) and glass-filled thermoplastic insulation. The blue color variant may be selected for visual identification purposes in applications where color coding is beneficial. This part is suitable when extended high-temperature performance is required.

All substitute parts are electrically and mechanically interchangeable based on identical pitch, position count, contact configuration, and crimp termination method. No design modifications are required for substitution.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0050579318 be used as a direct replacement for the TE Connectivity 1-103688-7?

A: Yes. Both parts share identical electrical and mechanical parameters: 18 positions, 0.100" (2.54mm) pitch, single-row configuration, female socket contacts, and crimp termination. The difference in insulation material (polyester glass-filled versus thermoplastic) does not affect functional interchangeability. Operating temperature range is -40°C to 105°C for the Molex part, which covers standard applications. If your application requires operation below -40°C, the TE Connectivity or Amphenol ICC 65240-018LF parts are required.

Q: What is the primary difference between the Amphenol ICC 65039-019LF and 65240-018LF parts?

A: The primary differences are color (black versus blue) and operating temperature range. The 65240-018LF supports -65°C to 125°C, providing extended low and high-temperature capability compared to the 65039-019LF range of -40°C to 105°C. Both parts use glass-filled insulation materials and maintain identical electrical and mechanical specifications for the 18-position, 2.54mm pitch configuration.

Q: Are all substitute parts RoHS compliant?

A: Yes. All four parts listed are RoHS compliant. The TE Connectivity 1-103688-7 and Molex 0050579318 carry ROHS3 Compliant status. The Amphenol ICC parts (65039-019LF and 65240-018LF) carry RoHS Compliant status. Both compliance levels are acceptable for regulated applications.

Q: Does the color difference in the 65240-018LF (blue) affect electrical performance?

A: No. Color is a visual identification feature only and does not affect electrical or mechanical performance. The blue color variant of the 65240-018LF can be selected when color coding is used for circuit identification or assembly organization purposes.

Q: What is the significance of the Moisture Sensitivity Level (MSL) rating of 1?

A: MSL 1 (Unlimited) indicates that these connector housings have unlimited shelf life and do not require special moisture-controlled storage conditions. This applies to all four substitute parts listed, simplifying inventory management and storage requirements.

Q: Can I substitute the 65240-018LF if my application operates at 120°C?

A: Yes. The 65240-018LF supports operating temperatures up to 125°C, making it suitable for applications requiring 120°C operation. The other three parts (1-103688-7, 0050579318, and 65039-019LF) are limited to 105°C maximum and would not be suitable for this application.

Q: Are contacts included with these connector housings?

A: No. All four parts are connector housings only. Contacts are not included and must be ordered separately. Ensure that selected contacts are compatible with the 0.100" (2.54mm) pitch and crimp termination method specified for these housings.
