• Pitch spacing (0.100" / 2.54mm)
• Mounting configuration (Through Hole, Right Angle)
• Contact dimensions (mating length, post length, insulation height)
• Contact shape (Square)

Electrical Performance:

• Operating temperature range (-65°C ~ 105°C)
• Current rating (3A)
• Contact material (Copper Alloy)
• Flammability rating (UL94 V-0)

Functional Characteristics:

• Style (Board to Board or Cable)
• Shrouding (Unshrouded)
• Fastening type (Push-Pull)
• Number of positions loaded (All)

The substitute part 5-103329-3 maintains equivalence across all mechanical and electrical parameters while differing in product status (Active vs. Obsolete), termination method (Solder only vs. Press-Fit and Solder), contact finish composition (Tin vs. Tin-Lead), and regulatory compliance status (RoHS Compliant vs. RoHS non-compliant).

Parameter Comparison

Engineering Selection Recommendations

The 5-103329-3 serves as the active equivalent to the obsolete 104349-1. Both connectors maintain identical mechanical and electrical specifications across all critical parameters including pitch spacing, contact dimensions, temperature range, and current rating.

Product Status Consideration: The 104349-1 is classified as obsolete, while the 5-103329-3 maintains active product status. For new designs, ongoing production, and long-term component availability, the 5-103329-3 is the appropriate selection.

Regulatory Compliance: The 5-103329-3 is RoHS Compliant, whereas the 104349-1 is RoHS non-compliant. Applications subject to RoHS directives or requiring compliance documentation must utilize the 5-103329-3.

Contact Finish Specification: The 104349-1 features Tin-Lead contact finish, while the 5-103329-3 utilizes Tin contact finish. Both finishes provide equivalent electrical performance and corrosion resistance within the specified operating parameters.

Termination Method: The 104349-1 supports both Press-Fit and Solder termination methods. The 5-103329-3 supports Solder termination only. Design implementations utilizing Press-Fit termination exclusively require the 104349-1 or alternative parts supporting this method.

Frequently Asked Questions (FAQ)

Q: Can the 5-103329-3 directly replace the 104349-1 in existing applications?

A: The 5-103329-3 is mechanically and electrically equivalent to the 104349-1 across all critical parameters. Direct replacement is supported for applications utilizing solder termination. Applications requiring Press-Fit termination capability must retain the 104349-1 or identify alternative parts supporting this termination method.

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

A: Both Tin-Lead and Tin finishes provide equivalent electrical conductivity and corrosion resistance within the specified operating temperature range (-65°C ~ 105°C) and current rating (3A). The contact finish difference does not affect functional compatibility or electrical performance in standard applications.

Q: Why is the 104349-1 classified as obsolete?

A: The 104349-1 is obsolete due to product lifecycle management by TE Connectivity. The 5-103329-3 represents the active continuation of this connector series within the AMPMODU Mod II family.

Q: Are there packaging differences between these parts?

A: The 104349-1 packaging specification is not provided in the technical data. The 5-103329-3 is supplied in Bulk packaging. Packaging differences do not affect connector functionality or electrical performance.

Q: Does the RoHS compliance difference affect electrical performance?

A: RoHS compliance status reflects regulatory and material composition requirements, not electrical performance. Both parts maintain identical electrical specifications. RoHS Compliance is a regulatory requirement for applications subject to RoHS directives.

Q: What is the voltage rating for the 5-103329-3?

A: The voltage rating for the 5-103329-3 is not specified in the provided technical data. The 104349-1 specifies a 30VAC voltage rating. For applications requiring explicit voltage rating confirmation, contact the manufacturer directly.

Q: Are these connectors suitable for high-temperature applications?

A: Both connectors operate within the temperature range of -65°C to 105°C. Applications requiring operation outside this range require alternative connector selection.

Q: What is the current-carrying capacity of these connectors?

A: Both connectors are rated for 3A continuous current. Applications requiring higher current capacity require alternative connector selection.
