TE Connectivity AMP Connectors 2-103648-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 2-103648-3 is a 24-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 single-row configurations. The part is classified as Active product status with full RoHS compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct functional replacement in applications where the core connector characteristics remain constant.

Substitute Part Grouping Explanation

Substitute parts for the 2-103648-3 are qualified based on strict alignment of core electrical and mechanical parameters. The following parameters must match or be compatible for substitution eligibility:

Connector Type: Receptacle
Contact Type: Female Socket
Number of Positions: 24
Pitch: 0.100" (2.54mm)
Number of Rows: 1
Mounting Type: Free Hanging (In-Line)
Contact Termination: Crimp
Moisture Sensitivity Level: 1 (Unlimited)

Variations in color, insulation material composition, operating temperature range, and manufacturer series do not preclude substitution when all core parameters remain constant. All identified substitutes maintain Active product status and RoHS compliance certifications.

Engineering Selection Recommendations

All three parts maintain Active product status and meet RoHS compliance requirements, establishing baseline qualification for substitution. The 2-103648-3 and 65240-024LF both support the full operating temperature range of -65°C to 105°C or higher, while the Molex 0050579024 operates within -40°C to 105°C. Selection between these substitutes depends on application-specific temperature requirements.

The 2-103648-3 and 0050579024 are available in black color, while the 65240-024LF is supplied in blue. Insulation material differs across the three parts: the original uses thermoplastic, the Molex substitute uses polyester with glass fill, and the Amphenol ICC substitute uses thermoplastic with glass fill. These material variations do not affect electrical or mechanical compatibility when all core connector parameters remain aligned.

All parts are supplied in bulk packaging with contacts not included. Inventory availability varies: 937 units for the original, 2860 units for the Molex part, and 3853 units for the Amphenol ICC part.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0050579024 directly replace the TE Connectivity 2-103648-3?

A: Yes. Both parts share identical core parameters: 24-position receptacle, female socket contacts, 0.100" (2.54mm) pitch, single-row configuration, free-hanging in-line mounting, and crimp termination. The operating temperature range of the Molex part (-40°C to 105°C) covers the upper portion of the original specification. Color and insulation material differences do not affect functional compatibility.

Q: What are the temperature considerations when selecting between substitutes?

A: The TE Connectivity 2-103648-3 operates from -65°C to 105°C. The Molex 0050579024 operates from -40°C to 105°C, which is suitable for applications not requiring the full lower temperature range. The Amphenol ICC 65240-024LF extends to -65°C to 125°C, providing broader temperature coverage.

Q: Does the color difference between parts affect substitution?

A: Color is a visual identifier only and does not affect electrical or mechanical performance. The 2-103648-3 and 0050579024 are black; the 65240-024LF is blue. Selection based on color depends on application requirements or assembly documentation specifications.

Q: Are contacts included with these connector housings?

A: No. All three parts are supplied as housings only. Contacts must be sourced separately and are not included in the package.

Q: What is the significance of the Moisture Sensitivity Level rating?

A: All three parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly. These parts do not require special moisture control measures.

Q: How do the RoHS compliance statuses differ?

A: The TE Connectivity 2-103648-3 is RoHS Compliant. The Molex 0050579024 is ROHS3 Compliant, representing a more recent revision of the RoHS directive. The Amphenol ICC 65240-024LF is RoHS Compliant. All three meet current environmental compliance requirements.
