TE Connectivity 2-104348-7 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 2-104348-7 is a rectangular connector header manufactured under the AMPMODU Mod II series. This through-hole, right-angle header connector features 40 positions at 0.100" (2.54mm) pitch and is designed for board-to-board or cable applications. The connector utilizes male pin contacts with gold-plated mating surfaces and tin-lead post finishes.

The 2-104348-7 carries an obsolete product status, which necessitates identification of active equivalent components for new designs and ongoing production requirements. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct interchangeability without design modifications.

The 7-104348-7 differs only in product status (Active versus Obsolete) and post contact finish specification (Tin versus Tin-Lead), with identical post finish thickness of 100.0µin (2.54µm).

Parameter Comparison

Engineering Selection Recommendations

The 7-104348-7 is the direct equivalent substitute for the obsolete 2-104348-7. Both connectors are manufactured by TE Connectivity within the AMPMODU Mod II series and maintain identical electrical and mechanical specifications across all critical parameters.

Primary Advantage of 7-104348-7: The substitute part carries Active product status, ensuring continued availability and supply chain support. Additionally, the 7-104348-7 is RoHS Compliant, whereas the 2-104348-7 is RoHS non-compliant. This compliance improvement aligns with current regulatory requirements for electronic components in many jurisdictions.

Post Contact Finish Consideration: The 7-104348-7 specifies Tin post finish compared to the Tin-Lead post finish of the 2-104348-7. Both finishes maintain identical thickness specifications of 100.0µin (2.54µm). The transition from Tin-Lead to Tin reflects industry-wide compliance with lead-free manufacturing standards and does not affect mechanical or electrical interchangeability.

Packaging: The 7-104348-7 is supplied in Bulk packaging, whereas packaging information for the 2-104348-7 is not specified. This distinction affects procurement and inventory management but does not impact component functionality.

Frequently Asked Questions (FAQ)

Q: Can the 7-104348-7 be used as a direct replacement for the 2-104348-7 in existing designs?

A: Yes. The 7-104348-7 maintains identical electrical and mechanical specifications across all critical parameters including contact type, pitch, position count, mounting configuration, and contact dimensions. Direct substitution is supported without design modifications.

Q: What is the significance of the post contact finish difference between Tin-Lead and Tin?

A: Both finishes are applied at identical thickness (100.0µin / 2.54µm) and serve the same functional purpose of providing a solderable surface for through-hole termination. The transition to Tin reflects lead-free manufacturing compliance and does not affect electrical or mechanical performance.

Q: Does the RoHS Compliant status of the 7-104348-7 affect compatibility with the 2-104348-7?

A: No. RoHS compliance status does not affect electrical or mechanical interchangeability. The 7-104348-7 offers improved regulatory compliance for applications subject to RoHS requirements, while maintaining full compatibility with designs originally specified for the 2-104348-7.

Q: Are there any differences in contact plating specifications between the two parts?

A: The mating contact finish specifications are identical: both parts feature gold-plated contacts at 15.0µin (0.38µm) thickness. This ensures equivalent contact resistance and mating performance.

Q: What is the significance of the Active product status for the 7-104348-7?

A: Active product status indicates that the 7-104348-7 is currently manufactured and supported by TE Connectivity. This ensures ongoing availability, consistent supply chain access, and technical support. The 2-104348-7 is classified as Obsolete, which may result in limited availability and eventual discontinuation.

Q: Are the mechanical dimensions identical between both parts?

A: Yes. Both connectors share identical mechanical specifications including contact length (mating: 0.230" / 5.84mm; post: 0.120" / 3.05mm), insulation height (0.138" / 3.50mm), and overall form factor. This ensures compatibility with existing PCB layouts and mating connector designs.

Q: What packaging options are available for the 7-104348-7?

A: The 7-104348-7 is supplied in Bulk packaging. Packaging specifications for the 2-104348-7 are not provided in the technical documentation.
