Amphenol ICC 54101-T08-04 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 54101-T08-04 is a rectangular connector header for through-hole mounting with 4 positions at 0.100" (2.54mm) pitch. This BERGSTIK® series connector is designed for board-to-board applications and is currently in active production status. Finding equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate different manufacturing preferences or availability constraints across multiple connector manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 54101-T08-04 is determined by the following critical parameters:

• Connector Type: Must be Header
• Contact Type: Must be Male Pin
• Number of Positions: Must be 4
• Pitch - Mating: Must be 0.100" (2.54mm)
• Number of Rows: Must be 1
• Mounting Type: Must be Through Hole
• Termination: Must be Solder
• Fastening Type: Must be Push-Pull
• Shrouding: Must be Unshrouded
• Style: Must be Board to Board or Board to Board/Cable compatible

All four substitute parts meet these core substitution criteria. Variations in contact length, insulation height, contact finish thickness, and material composition are within acceptable tolerance ranges for this connector category and do not prevent functional substitution in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are active production items from established connector manufacturers and meet the core functional requirements for 4-position, 0.100" pitch through-hole header applications.

RoHS Compliance Consideration: The original Amphenol ICC 54101-T08-04 is RoHS non-compliant. All substitute parts (Molex 0423751246, Mill-Max 350-10-104-00-006000, Samtec TS-104-T-AA, and Samtec TS-104-T-A-1) are ROHS3 compliant. For applications requiring RoHS compliance, any of the four substitutes is suitable. For legacy applications requiring RoHS non-compliant components, the original part remains the appropriate choice.

Contact Finish Consideration: The Mill-Max 350-10-104-00-006000 features gold plating on mating contacts (10.0µin thickness) compared to tin plating on the original and other substitutes. Gold-plated contacts provide enhanced corrosion resistance and are suitable for applications requiring extended shelf life or exposure to corrosive environments.

Inventory Availability: Molex 0423751246 has the highest inventory level (23,912 pcs), followed by Samtec TS-104-T-AA (5,112 pcs), Samtec TS-104-T-A-1 (1,005 pcs), and Mill-Max 350-10-104-00-006000 (773 pcs).

Frequently Asked Questions (FAQ)

Q: Can I substitute the Amphenol ICC 54101-T08-04 with any of these four parts?

A: Yes. All four substitute parts meet the critical functional parameters: 4-position header, 0.100" (2.54mm) pitch, male pin contacts, through-hole solder termination, and push-pull fastening. They are electrically and mechanically compatible for standard board-to-board applications.

Q: What is the difference between the Molex 0423751246 and the Amphenol ICC 54101-T08-04?

A: The Molex part is ROHS3 compliant (the original is not), has a slightly longer mating contact (0.240" vs. 0.230"), and a slightly lower insulation height (0.090" vs. 0.100"). The Molex part also supports breakaway configuration. These differences do not affect functional compatibility in standard applications.

Q: Why does the Mill-Max 350-10-104-00-006000 have gold-plated contacts?

A: Gold plating provides superior corrosion resistance compared to tin plating. This is beneficial for applications with extended storage periods, high-humidity environments, or where contact reliability over extended service life is critical. The gold plating thickness (10.0µin) is standard for this connector category.

Q: Are there differences in contact geometry between these parts?

A: Yes. The Amphenol ICC, Molex, and Samtec parts feature square-shaped contacts. The Mill-Max 350-10-104-00-006000 has circular-shaped contacts. Both geometries are standard for 0.100" pitch headers and are compatible with standard mating receptacles designed for this pitch.

Q: Which substitute should I choose for a new design?

A: Selection depends on specific requirements. For RoHS compliance, any of the four substitutes is suitable. For maximum inventory availability, the Molex 0423751246 is recommended. For enhanced corrosion resistance, the Mill-Max 350-10-104-00-006000 is appropriate. For Samtec preference, both TS-104-T-AA and TS-104-T-A-1 are functionally equivalent.

Q: What is the difference between Samtec TS-104-T-AA and TS-104-T-A-1?

A: Both are 4-position headers with identical electrical and mechanical specifications. The primary difference is REACH status: TS-104-T-AA is REACH Affected, while TS-104-T-A-1 is not specified for REACH status in the provided data. For applications subject to REACH regulations, verify current REACH compliance status with Samtec directly.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, for applications where the original Amphenol ICC 54101-T08-04 is currently in use. The substitute parts have compatible pitch, contact type, and mounting characteristics. Verify PCB footprint compatibility, as minor variations in contact length and insulation height may affect board layout in space-constrained designs.
