Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-103906-3 connector is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• 14-position configuration with 0.100" (2.54mm) pitch spacing
• Through-hole, right-angle mounting orientation
• Shrouded 4-wall design with keying slot
• Contact dimensions: 0.230" (5.84mm) mating length and 0.130" (3.30mm) post length
• Insulation height of 0.200" (5.08mm)

Electrical Performance:

• 3A current rating
• Operating temperature range of -65°C to 105°C
• UL94 V-0 flammability rating
• Solder termination method

Material Specifications:

• Brass contact material
• Thermoplastic insulation
• Gold-plated mating contacts at 30.0µin (0.76µm) thickness
• Post contact plating at 100.0µin (2.54µm) thickness

The substitute part 6-104935-3 meets all mechanical and electrical requirements for direct substitution. The primary difference is the post contact finish specification (tin versus tin-lead) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 6-104935-3 is a direct functional equivalent to the 1-103906-3 for all mechanical and electrical applications. Both connectors are active production parts from the same AMPMODU MTE series with identical dimensional specifications, contact configurations, and performance ratings.

Compliance Considerations:

The 6-104935-3 is RoHS Compliant, whereas the 1-103906-3 is marked as Not applicable for RoHS status. Applications requiring RoHS compliance should specify the 6-104935-3 part number.

Contact Finish Specification:

The primary technical difference between the two parts is the post contact finish. The 1-103906-3 features tin-lead plating on the posts, while the 6-104935-3 uses tin plating. Both finishes are applied at 100.0µin (2.54µm) thickness and provide equivalent solder joint reliability for through-hole termination applications.

Inventory Availability:

The 6-104935-3 maintains significantly higher inventory levels (19645 pieces) compared to the 1-103906-3 (1037 pieces), making it the preferred selection for high-volume production requirements or extended lead-time mitigation.

Both parts are suitable for automotive, general purpose, medical, and telecommunications applications with identical operating temperature ranges and current ratings.

Frequently Asked Questions (FAQ)

Q: Are the 1-103906-3 and 6-104935-3 connectors mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 14-position configuration, 0.100" (2.54mm) pitch, through-hole right-angle mounting, shrouded 4-wall design, and all contact dimensions. They are directly interchangeable in board layouts and mating applications.

Q: What is the difference between tin-lead and tin post plating?

A: The 1-103906-3 uses tin-lead plating while the 6-104935-3 uses tin plating on the solder posts. Both finishes are applied at 100.0µin (2.54µm) thickness and provide equivalent solder joint performance for through-hole termination.
