TE Connectivity AMP Connectors 1-103904-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1-103904-3 is a rectangular connector header designed for through-hole, right-angle mounting applications. This connector features 14 positions at 0.100" (2.54mm) pitch with shrouded 4-wall construction and male pin contacts. The part is classified as Active product status and is suitable for board-to-board or cable interconnection in automotive, general purpose, medical, and telecommunications applications. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements necessitate alternative specifications within compatible parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 1-103904-3 are identified based on strict equivalence of critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that must align for functional compatibility:

Critical Matching Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 14
• Number of Rows: 1
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Contact Shape: Square
• Material Flammability Rating: UL94 V-0

The Molex 0705530013 connector meets all critical matching parameters and is therefore classified as a direct substitute. Both connectors share identical pitch spacing, position count, mounting orientation, and shrouding configuration, enabling mechanical and electrical interchangeability in applications requiring these specifications.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 1-103904-3 Selection Criteria: The TE Connectivity part is appropriate for applications requiring the extended lower operating temperature limit of -65°C. This part carries RoHS non-compliant status and REACH Affected designation, which may impact procurement for regulated markets or applications with specific environmental compliance requirements.

Molex 0705530013 Selection Criteria: The Molex substitute is appropriate for applications where ROHS3 compliance and REACH Unaffected status are required. The operating temperature range of -40°C to 105°C is suitable for applications not requiring the extended low-temperature performance of the TE Connectivity part. The Molex connector uses phosphor bronze contact material and glass-filled polyester insulation, providing alternative material specifications while maintaining mechanical and electrical compatibility.

Both parts are Active product status and carry UL94 V-0 flammability ratings. Selection between these parts should be based on compliance requirements, operating temperature specifications, and material composition needs specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0705530013 be used as a direct replacement for the TE Connectivity 1-103904-3?

A: The Molex 0705530013 is mechanically and electrically compatible with the TE Connectivity 1-103904-3 for applications operating within the -40°C to 105°C temperature range. Both connectors share identical pitch spacing (0.100"), position count (14), mounting orientation (through-hole right-angle), and shrouding configuration (4-wall). Applications requiring operation below -40°C must use the TE Connectivity part.

Q: What are the key differences between these two connectors?

A: The primary differences are: (1) Operating temperature range: TE Connectivity supports -65°C to 105°C while Molex supports -40°C to 105°C; (2) Contact material: TE Connectivity uses brass while Molex uses phosphor bronze; (3) Insulation material: TE Connectivity uses thermoplastic while Molex uses polyester glass-filled; (4) Compliance status: Molex is ROHS3 compliant and REACH unaffected, while TE Connectivity is RoHS non-compliant and REACH affected; (5) Contact finish thickness on mating surface: TE Connectivity specifies 30.0µin while Molex specifies 15.0µin.

Q: Are there voltage or current rating differences between these connectors?

A: The TE Connectivity 1-103904-3 specifies a current rating of 3A. The Molex 0705530013 specifies a voltage rating of 250V. The TE Connectivity part does not provide a voltage rating specification in the available data, and the Molex part does not provide a current rating specification. Applications requiring specific voltage or current performance should verify these parameters against actual application requirements.

Q: What packaging is available for these connectors?

A: Both the TE Connectivity 1-103904-3 and Molex 0705530013 are supplied in tube packaging, suitable for automated assembly processes and standard component handling.

Q: Which connector should be selected for automotive applications?

A: Both connectors are rated for automotive applications. Selection should be based on the specific operating temperature requirements and compliance mandates of the automotive system. The TE Connectivity part supports extended low-temperature operation to -65°C, while the Molex part provides ROHS3 compliance and REACH unaffected status.
