TE Connectivity AMP Connectors 1-103688-8 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1-103688-8 is a 19-position rectangular connector receptacle housing designed for 0.100" (2.54mm) pitch applications. This component functions as a female socket receptacle for in-line, free-hanging mounting configurations. The part is Active in product status and widely used in applications requiring standard rectangular connector interfaces. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when inventory requirements necessitate alternative manufacturers.

Engineering Selection Recommendations

Both the 1-103688-8 and 65039-018LF are Active products with full regulatory compliance. Selection between these parts should be based on the following engineering considerations:

1-103688-8 (TE Connectivity AMP Connectors)

ROHS3 Compliant
Operating temperature range: -65°C ~ 105°C
Insulation material: Thermoplastic
Series: AMPMODU MTE
Suitable for applications requiring extended low-temperature operation down to -65°C

65039-018LF (Amphenol ICC Mini-PV™, Basics+)

RoHS Compliant
Operating temperature range: -40°C ~ 105°C
Insulation material: Polyphenylene, Modified
Series: Mini-PV™, Basics+
Suitable for applications within -40°C ~ 105°C temperature envelope
Higher inventory availability (1647 Pcs vs. 888 Pcs)

Both parts share identical mechanical and electrical parameters for 19-position, 2.54mm pitch receptacle housings with crimp termination. The primary differentiation is the lower operating temperature limit and insulation material composition. Selection should align with specific application temperature requirements and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can the 65039-018LF substitute for the 1-103688-8 in all applications?

A: The 65039-018LF is mechanically and electrically equivalent for applications operating within the -40°C ~ 105°C temperature range. Applications requiring operation below -40°C must use the 1-103688-8, which operates to -65°C.

Q: Are the insulation materials interchangeable?

A: Both insulation materials are thermoplastic-based. The 1-103688-8 uses Thermoplastic, while the 65039-018LF uses Polyphenylene, Modified. Both materials provide equivalent electrical insulation properties for standard rectangular connector applications at the specified operating temperatures.

Q: Do these parts require contacts to be purchased separately?

A: Yes. Both the 1-103688-8 and 65039-018LF are receptacle housings only. Contacts are not included and must be sourced separately according to application requirements.

Q: Are both parts RoHS compliant?

A: Yes. The 1-103688-8 is ROHS3 Compliant, and the 65039-018LF is RoHS Compliant. Both meet regulatory requirements for restricted substance elimination.

Q: What is the pitch specification, and why is it critical?

A: Both parts feature 0.100" (2.54mm) pitch spacing. Pitch determines the center-to-center distance between contact positions and is critical for mechanical compatibility with mating connectors and printed circuit board layouts.

Q: Can these receptacles be used in applications requiring different mounting orientations?

A: Both parts are specified for Free Hanging (In-Line) mounting. Mounting type is fixed and cannot be altered. Applications requiring different mounting configurations require alternative part numbers.

Q: What is the significance of MSL Level 1?

A: Moisture Sensitivity Level 1 (Unlimited) indicates these components have unlimited shelf life and do not require special moisture-controlled storage or handling procedures prior to assembly.
