TE Connectivity AMP Connectors 104349-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 104349-2 is a rectangular connector header designed for through-hole, right-angle mounting applications. This connector features a 4-position configuration with 0.100" (2.54mm) pitch spacing and is part of the AMPMODU Mod II series. The part is classified as obsolete, necessitating identification of equivalent substitute components for ongoing design requirements and production continuity. Substitute parts must maintain electrical and mechanical compatibility while meeting current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 104349-2 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Header, Breakaway
• Contact type: Male Pin
• Number of positions: 4
• Number of rows: 1
• Pitch - mating: 0.100" (2.54mm)
• Mounting type: Through Hole
• Termination: Solder-compatible
• Fastening type: Push-Pull
• Contact shape: Square
• Insulation color: Black
• Moisture sensitivity level: 1 (Unlimited)

Acceptable Variations:

• Contact finish composition (Tin-Lead to Tin or Gold)
• Contact finish thickness within industry tolerance
• Insulation material composition (thermoplastic or unspecified)
• Mounting orientation (right-angle or straight, provided through-hole compatibility is maintained)
• Product status transition from obsolete to active

The two identified substitute parts meet these criteria while offering improved compliance status and active product availability.

Engineering Selection Recommendations

TE Connectivity 5-103329-4 (MFR Recommended Substitute)

The TE Connectivity 5-103329-4 is the manufacturer-recommended substitute for the obsolete 104349-2. This part maintains identical pitch, position count, and contact geometry while transitioning to active product status. The primary distinction is the shift from Tin-Lead to Tin contact finish and the achievement of ROHS3 compliance. This substitute is suitable for applications requiring RoHS compliance and modern supply chain continuity. The part remains within the same AMPMODU Mod II series, ensuring design compatibility.

Molex 0901210764 (Alternative Substitute)

The Molex 0901210764 provides an alternative cross-manufacturer substitute with active product status and ROHS3 compliance. This part maintains the critical 4-position, 2.54mm pitch configuration and push-pull fastening mechanism. Differences include gold contact finish, brass contact material, and polyester glass-filled insulation. The contact length variations (mating and post) are minor and within typical mechanical tolerance ranges. This substitute is applicable for designs requiring multi-source qualification or Molex component standardization.

Compliance Considerations

Both substitute parts achieve ROHS3 compliance, addressing the non-compliant status of the original 104349-2. Selection between substitutes should be based on existing supply chain relationships, design qualification requirements, and compliance mandates specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5-103329-4 be used as a direct replacement for the 104349-2?

A: The 5-103329-4 maintains all critical electrical and mechanical parameters required for substitution, including pitch, position count, contact type, and fastening mechanism. The primary difference is the mounting type specification (Through Hole versus Through Hole, Right Angle). Verify that your PCB layout accommodates this variation before implementation.

Q: What is the significance of the contact finish change from Tin-Lead to Tin?

A: The transition from Tin-Lead to Tin contact finish reflects modern RoHS compliance requirements. Tin provides equivalent electrical conductivity and contact reliability for the specified 3A current rating and 30VAC voltage rating. This change does not affect functional compatibility in standard applications.

Q: Are the Molex 0901210764 and TE Connectivity 5-103329-4 interchangeable?

A: Both parts meet the core substitution criteria of 4-position, 2.54mm pitch, male pin headers with push-pull fastening. However, they differ in contact material (Brass versus Copper Alloy), contact finish (Gold versus Tin), and insulation material composition. Interchangeability depends on application-specific requirements for contact resistance, environmental exposure, and design qualification status. Cross-qualification may be necessary.

Q: What does the Moisture Sensitivity Level (MSL) rating of 1 indicate?

A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and requires no special moisture control during storage or handling. This applies to all three parts in this comparison and simplifies inventory management.

Q: Why does the 104349-2 specify both Press-Fit and Solder termination while the substitutes specify only Solder?

A: The original 104349-2 supported dual termination methods. The substitutes are optimized for solder termination, which is the standard assembly method for modern through-hole rectangular connectors. Verify that your assembly process uses solder termination before selecting a substitute.

Q: Are there any contact length differences that affect PCB design?

A: The Molex 0901210764 has slightly longer mating contact length (0.266" versus 0.230") and marginally shorter post length (0.114" versus 0.120"). These variations are within typical mechanical tolerance ranges and do not require PCB redesign for standard applications. Verify clearances in high-density layouts.

Q: What is the current inventory status for these parts?

A: The 104349-2 has 1112 pieces in stock (obsolete status). The 5-103329-4 has 630 pieces available (active status). The 0901210764 has 5101 pieces available (active status). Inventory levels should be confirmed with your supplier for production planning.
