TE Connectivity AMP Connectors 1-104481-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1-104481-1 is an active rectangular connector socket contact designed for crimp termination applications. This component is part of the AMPMODU Short Point series and features gold plating for enhanced conductivity and corrosion resistance. The part is manufactured to ROHS3 compliance standards and maintains unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent functional performance can be achieved through alternative manufacturers while maintaining compatibility with the specified wire gauge, termination method, and contact finish requirements. Alternative sources provide equivalent socket contact solutions for applications requiring rectangular connector assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector socket contacts is determined by the following critical parameters:

Primary Compatibility Criteria:

• Contact type classification (Socket)
• Termination method (Crimp)
• Contact finish material (Gold or equivalent conductive finish)
• Wire gauge range overlap with the main part specification

Secondary Compatibility Factors:

• Regulatory compliance (RoHS3, REACH status)
• Moisture sensitivity rating
• Product active status

The identified substitute parts maintain socket contact configuration and crimp termination methodology. Wire gauge compatibility is evaluated based on overlap within the specified ranges. Contact finish material and thickness are documented to support electrical performance assessment in applications requiring specific conductivity characteristics.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 1-104481-1 (Primary Part)

This part maintains active product status with full ROHS3 compliance and REACH unaffected designation. The gold contact finish with 30.0µin thickness provides specified electrical performance for 28-32 AWG wire applications. MSL 1 rating supports unlimited moisture exposure conditions. Cut Tape packaging is suitable for standard component handling and assembly processes.

Molex 0503978000 (Substitute - Limited Compatibility)

This part operates as an active rectangular connector socket contact with crimp termination. Wire gauge specification (22-28 AWG) provides partial overlap with the main part at 28 AWG. Contact finish is tin rather than gold. RoHS and REACH compliance status are not specified in available documentation. Tape & Reel packaging differs from the main part. This substitute is applicable only in applications where tin contact finish is functionally equivalent to gold and wire gauge overlap at 28 AWG is acceptable.

Hirose Electric A1-2226SCC (Substitute - Partial Compatibility)

This part maintains active status with ROHS3 compliance and REACH unaffected designation, matching the main part regulatory profile. Gold contact finish aligns with the main part material specification, though finish thickness (8.00µin) is significantly lower than the main part (30.0µin). Wire gauge specification (22-26 AWG) does not overlap with the main part range (28-32 AWG). MSL 1 rating matches the main part. This substitute is applicable only in applications where wire gauge requirements fall within the 22-26 AWG range and reduced contact finish thickness is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0503978000 be used as a direct replacement for the TE Connectivity 1-104481-1?

A: The Molex 0503978000 is not a direct replacement. While both are rectangular connector socket contacts with crimp termination, the Molex part features tin contact finish instead of gold and operates within a 22-28 AWG wire gauge range. Wire gauge overlap occurs only at 28 AWG. Application compatibility depends on whether tin finish provides equivalent electrical performance and whether the wire gauge requirement falls within the overlapping range.

Q: What is the significance of contact finish thickness differences between these parts?

A: Contact finish thickness affects electrical conductivity, corrosion resistance, and long-term reliability. The main part specifies 30.0µin gold plating, the Molex substitute provides 35.4µin tin plating, and the Hirose substitute provides 8.00µin gold plating. These differences influence performance in high-reliability applications and corrosive environments.

Q: Is the Hirose Electric A1-2226SCC compatible with 28-32 AWG wire applications?

A: No. The Hirose part is specified for 22-26 AWG wire gauge, which does not overlap with the main part's 28-32 AWG specification. This part is suitable only for applications requiring 22-26 AWG wire termination.

Q: How do packaging differences affect component selection?

A: The main part is supplied in Cut Tape (CT) packaging, the Molex substitute in Tape & Reel (TR), and the Hirose substitute in Bulk packaging. Packaging selection impacts inventory management, automated assembly compatibility, and component handling procedures. Selection depends on production volume and assembly equipment specifications.

Q: Are all three parts RoHS3 compliant?

A: The TE Connectivity main part and Hirose Electric substitute are both ROHS3 compliant. The Molex part's RoHS compliance status is not specified in available documentation. Regulatory compliance verification is required before selection for applications with RoHS requirements.

Q: What does MSL 1 (Unlimited) rating indicate?

A: MSL 1 indicates unlimited moisture sensitivity, meaning the component can be stored and handled without moisture control measures. Both the main part and Hirose substitute carry this rating. The Molex substitute lists MSL as Not Applicable, indicating different moisture handling requirements.
