Equivalent & Substitute Parts for Amphenol ICC 54201-G08-03

Part Overview

The Amphenol ICC 54201-G08-03 is a rectangular connector header designed for surface mount applications with 3 positions at 0.100" (2.54mm) pitch. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for new designs and production continuity. The BERGSTIK® series header features unshrouded male pins with gold-plated phosphor bronze contacts suitable for board-to-board connections.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 54201-G08-03 are identified based on the following critical parameters that determine functional equivalence:

• Number of Positions: 3 contacts
• Pitch: 0.100" (2.54mm) mating pitch
• Mounting Type: Surface Mount (SMD)
• Connector Category: Rectangular connectors suitable for board-to-board applications
• Contact Material and Finish: Gold-plated copper alloy contacts

The substitute parts listed below maintain these core electrical and mechanical parameters, enabling direct functional replacement in applications requiring a 3-position, 0.100" pitch surface mount connector. Substitute connectors utilize piston-type contacts rather than male pins, which is an acceptable variation within the rectangular connector category for this pitch and position count.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Mill-Max 812-22-003-30-006101

This part is the preferred substitute due to active product status and ROHS3 compliance. It maintains the critical electrical and mechanical parameters of the original 54201-G08-03 while offering improved regulatory compliance for new designs. The piston contact design provides equivalent functionality for board-to-board connections at 0.100" pitch with 3 positions.

Secondary Substitute: Mill-Max 812-22-003-30-007101

This alternative maintains identical electrical specifications and pitch configuration but is listed as discontinued at DiGi Electronics. Selection of this part should be evaluated based on current availability and supply chain requirements. Both Mill-Max substitutes provide ROHS3 compliance, addressing the non-compliance status of the original Amphenol ICC component.

The transition from the obsolete Amphenol ICC header to either Mill-Max piston connector requires verification of mechanical fit within the application's mating interface, as piston contacts differ geometrically from male pin headers despite maintaining equivalent electrical performance at the specified pitch and position count.

Frequently Asked Questions (FAQ)

Q: What makes these parts functionally equivalent to the 54201-G08-03?

A: All substitute parts maintain the critical parameters: 3-position configuration, 0.100" (2.54mm) pitch, surface mount technology, gold-plated contacts, and single-row layout. These parameters define compatibility for board-to-board rectangular connector applications in this category.

Q: Why is the contact type different (piston vs. male pin)?

A: Within the rectangular connector category at 0.100" pitch, both male pin headers and piston connectors serve equivalent functional roles in board-to-board applications. The piston design provides an alternative contact mechanism while maintaining electrical performance and pitch specifications.

Q: Are the Mill-Max substitutes compatible with the original mating connectors?

A: Mechanical compatibility depends on the mating connector design. The 0.100" pitch and 3-position configuration are maintained, but the piston contact geometry differs from the male pin header. Verification with the specific mating connector is required.

Q: What is the significance of RoHS compliance in selecting a substitute?

A: The original 54201-G08-03 is RoHS non-compliant. Both Mill-Max substitutes are ROHS3 compliant, making them suitable for applications subject to RoHS regulations. This is a key advantage for new product designs and markets with regulatory requirements.

Q: Which substitute should be selected for new designs?

A: The Mill-Max 812-22-003-30-006101 is recommended for new designs due to active product status and confirmed availability. The 812-22-003-30-007101 should be evaluated based on current supply chain status and long-term availability requirements.

Q: Are there differences in contact finish thickness between the main part and substitutes?

A: Yes. The 54201-G08-03 specifies 30.0µin (0.76µm) gold finish thickness, while both Mill-Max substitutes specify 20.0µin (0.51µm). Both thicknesses are within industry standards for gold-plated contacts and provide equivalent corrosion protection and electrical performance.
