TE Connectivity 2-104349-7 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 2-104349-7 is a rectangular connector header manufactured under the AMPMODU Mod II series. This through-hole, right-angle header accommodates 40 positions at 0.100" (2.54mm) pitch and is designed for board-to-board or cable interconnection applications. The connector features male pin contacts with tin-lead plating and operates across a temperature range of -65°C to 105°C.

The 2-104349-7 carries an obsolete product status. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for applications currently utilizing this connector.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2-104349-7 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• 40-position configuration at 0.100" (2.54mm) pitch
• Through-hole, right-angle mounting orientation
• Contact length specifications: 0.230" (5.84mm) mating, 0.120" (3.05mm) post
• Insulation height of 0.138" (3.50mm)
• Square contact geometry

Electrical Compatibility:

• 3A current rating
• Operating temperature range of -65°C to 105°C
• Copper alloy contact material
• Male pin contact type

Regulatory & Environmental:

• UL94 V-0 flammability rating
• RoHS compliance
• Moisture Sensitivity Level 1 (Unlimited)

The substitute part 9-103329-0 maintains full equivalence across all mechanical and electrical parameters. Differences in contact finish composition (tin versus tin-lead) and termination method (solder only versus press-fit and solder) do not affect functional interchangeability within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

The 9-103329-0 serves as the direct substitute for the obsolete 2-104349-7. Both connectors are manufactured by TE Connectivity within the AMPMODU Mod II series and maintain identical mechanical and electrical specifications across all critical parameters.

The primary distinction is product status: the 2-104349-7 is obsolete while the 9-103329-0 is active. This status difference ensures ongoing availability and supply chain continuity for new designs and production requirements.

Both parts maintain full RoHS compliance and carry identical regulatory certifications (UL94 V-0, EAR99, HTSUS 8536.69.4040). The contact finish composition differs (tin-lead versus tin), and the 9-103329-0 eliminates press-fit termination in favor of solder-only termination. These differences do not affect functional interchangeability within the specified electrical and mechanical parameter envelope.

Frequently Asked Questions (FAQ)

Q: Can the 9-103329-0 be used as a direct replacement for the 2-104349-7 in existing designs?

A: Yes. Both connectors share identical mechanical dimensions, electrical ratings, and contact specifications. The 40-position, 0.100" pitch configuration, through-hole right-angle mounting, and 3A current rating are equivalent across both parts.

Q: What is the significance of the contact finish difference between tin-lead and tin?

A: The contact finish composition does not affect electrical or mechanical compatibility. Both finishes provide equivalent contact resistance and durability within the specified operating temperature range of -65°C to 105°C. The tin finish on the 9-103329-0 reflects current manufacturing standards.

Q: Does the elimination of press-fit termination on the 9-103329-0 affect compatibility?

A: The 2-104349-7 supports both press-fit and solder termination methods. The 9-103329-0 supports solder termination only. For applications utilizing solder termination, this difference is not relevant. Applications requiring press-fit termination must retain the original 2-104349-7 or identify alternative solutions.

Q: Are both parts RoHS compliant?

A: Yes. Both the 2-104349-7 and 9-103329-0 are RoHS compliant and carry identical regulatory certifications including UL94 V-0 flammability rating.

Q: What is the packaging difference between these parts?

A: The 2-104349-7 is listed with unspecified packaging, while the 9-103329-0 is supplied in bulk packaging. Packaging format does not affect connector functionality or electrical performance.

Q: Why is the 2-104349-7 obsolete if the 9-103329-0 is functionally equivalent?

A: Product obsolescence reflects manufacturing lifecycle decisions by TE Connectivity. The 9-103329-0 represents the current active production part within the AMPMODU Mod II series for this connector configuration. Inventory availability of the 2-104349-7 (909 pieces) versus the 9-103329-0 (3435 pieces) reflects this status transition.
