TE Connectivity 5-146293-9 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 5-146293-9 is a 9-position rectangular connector header from the AMPMODU Mod II series, designed for through-hole mounting with 0.100" (2.54mm) pitch. This connector features male pin contacts with gold-plated mating surfaces and tin-plated posts, suitable for board-to-board or cable applications.

The 5-146293-9 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance requirements for legacy systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5-146293-9 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Connector series: AMPMODU Mod II
• Number of positions: 9
• Pitch specification: 0.100" (2.54mm)
• Contact type: Male Pin
• Mounting method: Through Hole
• Connector style: Header, Breakaway
• Current rating: 3A
• Operating temperature range: -65°C ~ 105°C
• Insulation material: Liquid Crystal Polymer (LCP)
• Contact finish: Gold (mating), Tin (post)

The substitute part 5-146281-9 maintains all critical electrical and mechanical parameters. The primary difference is the termination method: the original part supports both Press-Fit and Solder termination, while the substitute part supports Solder termination only. This distinction does not affect electrical or mechanical compatibility when solder termination is employed.

Engineering Selection Recommendations

The TE Connectivity 5-146281-9 is the direct substitute for the obsolete 5-146293-9 based on the following engineering criteria:

Product Status Alignment: The 5-146281-9 carries an active product status, ensuring ongoing availability and manufacturer support. The original 5-146293-9 is obsolete, making the substitute the appropriate selection for new designs and ongoing production support.

Electrical and Mechanical Compatibility: All critical electrical parameters (current rating, operating temperature range, contact materials, and finishes) are identical between the original and substitute parts. All mechanical dimensions, including contact lengths, insulation height, and pitch specifications, match exactly.

Compliance and Certifications: Both parts meet UL94 V-0 flammability requirements and are manufactured from identical insulation materials (Liquid Crystal Polymer). The original part is RoHS Compliant; compliance status for the substitute is not specified in available data.

Termination Consideration: The original part supports both Press-Fit and Solder termination methods. The substitute part supports Solder termination only. For applications utilizing solder termination exclusively, this difference presents no functional impact. Applications requiring press-fit termination capability must evaluate alternative solutions.

Supply Chain: The substitute part (5-146281-9) has 705 units in current inventory, providing immediate availability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the 5-146281-9 be used as a direct replacement for the 5-146293-9 in all applications?

A: The 5-146281-9 is a direct substitute for applications using solder termination. If your application requires press-fit termination capability, the substitute part does not support this method. Verify your termination method before selection.

Q: What is the primary difference between these two parts?
