Amphenol ICC 68002-103 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68002-103 is a rectangular connector header designed for through-hole mounting applications. This 3-position, 0.100" (2.54mm) pitch connector operates within the BERGSTIK® II series and features male pin contacts with gold plating. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 68002-103 is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — must match exactly for mechanical compatibility
• Connector Type: Header with male pin contacts
• Mounting Type: Through Hole solder termination
• Current Rating: 3A minimum
• Contact Finish: Gold plating on mating surfaces
• Material Flammability: UL94 V-0 compliance
• Operating Temperature Range: Must encompass or exceed -65°C ~ 130°C

The substitute part TE Connectivity AMP Connectors 4-103185-0 meets these core electrical and mechanical criteria. However, this part is a 40-position breakaway header, requiring position-specific selection or trimming to achieve functional equivalence for 3-position applications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 4-103185-0 serves as a functional substitute for the obsolete 68002-103 when the following conditions are met:

• The application requires only 3 positions from the 40-position breakaway header
• The operating temperature range does not exceed 105°C (note the 25°C reduction from the original specification)
• The reduced contact finish thickness (15.0µin vs. 30.0µin) is acceptable for the intended current and environmental conditions
• The 0.010" reduction in insulation height and 0.030" reduction in post length do not create mechanical interference with mating connectors or PCB layout constraints

Both parts maintain UL94 V-0 flammability compliance and 3A current rating. The substitute part is classified as obsolete, consistent with the original part status. RoHS compliance differs between the two parts; the main part is RoHS non-compliant while the substitute status is not applicable.

Frequently Asked Questions (FAQ)

Q: Can the 4-103185-0 directly replace the 68002-103 in existing designs?

A: Direct replacement is possible only if the application uses exactly 3 positions and the operating temperature remains below 105°C. The breakaway design of the 4-103185-0 allows removal of unused positions to achieve a 3-position configuration. Verify that the reduced insulation height (0.090" vs. 0.100") and post length (0.120" vs. 0.150") do not conflict with mating connector geometry or PCB trace routing.

Q: What is the significance of the contact finish thickness difference?

A: The main part specifies 30.0µin (0.76µm) gold plating on mating contacts, while the substitute provides 15.0µin (0.38µm). This reduction may affect long-term contact resistance stability and wear characteristics in high-cycle mating applications. Evaluate the expected number of mating cycles and environmental exposure for your application.

Q: Are there any compliance differences between these parts?

A: Both parts carry UL94 V-0 flammability ratings and support 3A current. The main part is RoHS non-compliant, while the substitute's RoHS status is not applicable. Verify compliance requirements for your specific application and regulatory jurisdiction.

Q: Why is the substitute a 40-position header when only 3 positions are needed?

A: The 4-103185-0 is a breakaway header design, allowing individual positions to be separated or removed. This design flexibility enables use in multiple applications with varying position counts. For a 3-position requirement, the header can be trimmed or individual positions can be selected during assembly.

Q: What is the impact of the 25°C reduction in maximum operating temperature?

A: The substitute part is rated to 105°C maximum, compared to the original 130°C specification. If your application operates near or above 105°C, the substitute may not be suitable. Confirm the actual operating temperature range of your system before proceeding with substitution.
