TE Connectivity 5-146273-6 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 5-146273-6 is a vertical rectangular connector header manufactured under the AMPMODU Mod II series. This through-hole component features 12 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing, designed for board-to-board or cable interconnection applications. The connector utilizes male pin contacts with gold-plated mating surfaces and tin-plated posts, rated for 3A continuous current operation across an extended temperature range of -65°C to 105°C.

The 5-146273-6 carries an obsolete product status. Locating equivalent substitute components becomes necessary when original stock depletion occurs or when design revisions require active-status alternatives that maintain full electrical and mechanical compatibility with existing circuit board layouts and mating connectors.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5-146261-6 serves as the direct substitute for the obsolete 5-146273-6 based on the following engineering criteria:

Electrical Equivalence: Both components maintain identical electrical specifications including 12-position configuration, 0.100" (2.54mm) pitch spacing, 3A current rating, and -65°C to 105°C operating temperature range. Contact materials, finishes, and thicknesses are identical across both mating and post surfaces.

Mechanical Equivalence: The 5-146261-6 preserves all mechanical dimensions and mounting characteristics of the original part. Through-hole mounting, breakaway header configuration, and LCP insulation material remain unchanged. Contact geometry, overall length, and insulation height specifications are identical.

Compliance Status: Both components carry RoHS compliance certification, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity classification. These certifications ensure regulatory and environmental compliance requirements are maintained.

Product Status Advantage: The 5-146261-6 carries active product status, ensuring continued availability and manufacturing support. This addresses the primary limitation of the obsolete 5-146273-6 by providing a component with established supply chain continuity.

Termination Consideration: The 5-146261-6 utilizes standard solder termination, compared to the kinked pin solder termination of the original part. Both termination methods are compatible with standard PCB through-hole soldering processes and produce equivalent mechanical and electrical connections.

Frequently Asked Questions (FAQ)

Q: Can the 5-146261-6 be used as a direct replacement for the 5-146273-6 in existing circuit board designs?

A: Yes. The 5-146261-6 maintains identical electrical and mechanical specifications across all critical parameters including position count, pitch spacing, contact configuration, current rating, and operating temperature range. The components are mechanically and electrically interchangeable in existing PCB layouts.

Q: What is the difference between kinked pin and standard solder termination?

A: Kinked pin termination incorporates a bend in the post section to provide additional mechanical retention during PCB assembly. Standard solder termination relies on solder joint formation for mechanical and electrical connection. Both methods produce equivalent electrical performance and mechanical reliability when properly soldered to PCB through-holes.

Q: Are the contact finish specifications identical between the two parts?

A: Yes. Both components feature gold-plated mating surfaces at 30.0µin (0.76µm) thickness and tin-plated posts at 100.0µin (2.54µm) thickness. Contact material composition is copper alloy for both parts.

Q: Does the 5-146261-6 meet the same compliance requirements as the original part?

A: Yes. The 5-146261-6 carries identical RoHS compliance certification, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity classification. Both components satisfy equivalent regulatory and environmental standards.

Q: What is the primary advantage of selecting the 5-146261-6 over the obsolete 5-146273-6?

A: The 5-146261-6 carries active product status, ensuring continued manufacturing availability and supply chain support. The obsolete 5-146273-6 faces potential stock depletion and discontinued production. Selecting the active substitute ensures long-term component availability for production and field service applications.

Q: Are there any dimensional differences between these connectors?

A: No. Both components maintain identical dimensional specifications including contact length (mating and post), overall contact length, insulation height, and pitch spacing. The connectors are dimensionally equivalent and occupy identical PCB footprints.

Q: Can both parts be used interchangeably in new designs?

A: Yes. The 5-146261-6 is suitable for new design implementations. The active product status and full electrical and mechanical equivalence make it the appropriate selection for new applications requiring 12-position, 2.54mm pitch rectangular connector headers.
