TE Connectivity 1-146443-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-146443-3 is a rectangular connector header classified as a vertical through-hole component with 26 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This connector is part of the AMPMODU Mod II series and features male pins with gold-plated mating contacts and tin-lead plated posts. The part is currently obsolete, making equivalent substitutes necessary for ongoing design requirements and board assembly operations. The connector is designed for board-to-board or cable applications with push-pull fastening and unshrouded configuration.

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-146443-3 is determined by strict equivalence across the following critical parameters:

Primary Matching Criteria:

26 positions in 2-row configuration
0.100" (2.54mm) mating pitch
0.100" (2.54mm) row spacing
Male pin contact type
Through-hole mounting with solder termination
Push-pull fastening mechanism
Unshrouded header design
Square contact shape
Copper alloy contact material
0.090" (2.29mm) insulation height

Secondary Compatibility Factors:

Contact length variations (mating and post lengths)
Overall contact length
Contact finish material and thickness
Insulation material composition
Packaging format

Substitute parts from Molex are grouped into three categories based on contact post length: standard post length (0.107"), extended post length (0.175"), and kinked pin post length (0.125"). All substitute parts maintain the core 26-position, 2-row, 2.54mm pitch configuration and are compatible with the original application requirements.

Engineering Selection Recommendations

Product Status Consideration: The TE Connectivity 1-146443-3 is classified as obsolete. All listed Molex substitute parts are active products with current manufacturing support and availability. Selection of an active substitute part ensures long-term supply chain continuity and access to technical support.

Compliance and Regulatory Status: The original TE Connectivity part is RoHS non-compliant and REACH affected. All Molex substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for new designs and manufacturing operations.

Contact Length Considerations: Substitute parts are available in four post length configurations:

Standard post length (0.107"): Molex 0010897260, 0010897261, 0010897262
Extended post length (0.175"): Molex 0702800601, 0702800641, 0702800681
Kinked pin post length (0.125"): Molex 0702871011, 0702871109, 0702871207
Compact post length (0.110"): Molex 0879142616

Selection depends on PCB thickness and application requirements. The Molex 0879142616 provides the closest overall contact length match to the original part at 0.430" (10.92mm) compared to the original 0.410" (10.41mm).

Contact Finish Selection: Gold-plated mating contacts are available in Molex parts 0010897260, 0010897262, 0702800641, 0702800681, 0702871109, and 0702871207. Tin-plated mating contacts are available in Molex parts 0010897261, 0702800601, 0702871011, and 0879142616. Selection should align with connector compatibility and application requirements.

Termination Type: Standard solder termination is available in all listed parts. Kinked pin solder termination is available in Molex C-Grid 70287 series parts (0702871011, 0702871109, 0702871207) for enhanced mechanical retention during assembly.

Frequently Asked Questions (FAQ)

Q: Can Molex C-Grid 70280 series parts directly replace the TE Connectivity 1-146443-3?

A: Yes. Molex C-Grid 70280 series parts (0010897260, 0010897261, 0010897262, 0702800601, 0702800641, 0702800681) maintain the same 26-position, 2-row, 2.54mm pitch configuration and are mechanically and electrically compatible. Selection among these parts depends on required post length and contact finish specifications.

Q: What is the difference between the standard post length and extended post length Molex parts?

A: Standard post length parts (0.107") are suitable for standard PCB thicknesses. Extended post length parts (0.175") accommodate thicker PCBs or applications requiring deeper solder penetration. The kinked pin variants (0.125") provide intermediate post length with enhanced mechanical retention during wave soldering.

Q: Are all Molex substitute parts RoHS compliant?

A: Yes. All listed Molex substitute parts are ROHS3 compliant, whereas the original TE Connectivity part is RoHS non-compliant. This compliance upgrade is beneficial for new designs and manufacturing operations subject to RoHS regulations.

Q: What is the difference between gold-plated and tin-plated mating contacts?

A: Gold-plated mating contacts provide superior corrosion resistance and lower contact resistance. Tin-plated mating contacts are suitable for general-purpose applications with lower cost. Selection depends on application environment and performance requirements.

Q: Can kinked pin termination parts be used in standard wave soldering processes?

A: Yes. Kinked pin termination (Molex 0702871011, 0702871109, 0702871207) is designed for standard wave soldering processes and provides enhanced mechanical retention during assembly compared to straight pin termination.

Q: What packaging formats are available for the Molex substitute parts?

A: Molex C-Grid 70280 and 70287 series parts are supplied in bulk packaging. Molex C-Grid 87914 series part (0879142616) is supplied in tray packaging. Packaging selection depends on assembly process requirements and inventory management practices.

Q: Is the Molex 0879142616 a direct replacement for the TE Connectivity 1-146443-3?

A: The Molex 0879142616 provides the closest dimensional match with overall contact length of 0.430" (10.92mm) compared to the original 0.410" (10.41mm). It features tin-plated mating contacts and tin-plated posts with standard solder termination. This part is suitable for applications where minimal dimensional variation is required.

Q: Are there any differences in insulation material between the original part and Molex substitutes?

A: The original TE Connectivity part does not specify insulation material. All Molex substitute parts use Liquid Crystal Polymer (LCP) glass-filled insulation with black color, providing superior mechanical and thermal properties compared to standard phenolic materials.

Q: What is the inventory availability for these substitute parts?

A: Inventory levels vary by part number, ranging from 648 to 3245 pieces in stock. The Molex 0879142616 has the highest inventory at 3245 pieces. Specific availability should be confirmed at time of procurement.
