Equivalent & Substitute Parts for 54201-T08-03

Part Overview

The Amphenol ICC 54201-T08-03 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, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. The BERGSTIK® series header features unshrouded male pin contacts with solder termination and push-pull fastening, suitable for board-to-board interconnection in compact layouts.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 54201-T08-03 is based on the following critical parameters that must align for functional equivalence:

• Connector Category: Rectangular connector for board-to-board interconnection
• Position Count: 3 positions
• Pitch Specification: 0.100" (2.54mm) mating pitch
• Mounting Configuration: Surface mount technology
• Row Configuration: Single row layout
• Electrical Interface: Contact finish and material suitable for mating with standard 2.54mm pitch receptacles

The substitute parts identified (Mill-Max 812-22-003-30-006101 and 812-22-003-30-007101) maintain these core parameters. However, they employ piston-type spring contacts rather than male pin headers, representing a different contact architecture within the same pitch and position specification. This distinction affects mating interface compatibility and must be evaluated against the receiving connector type in the target application.

Parameter Comparison

Engineering Selection Recommendations

812-22-003-30-006101 is the primary substitute option. This part maintains active product status with ROHS3 compliance, addressing regulatory requirements that the obsolete 54201-T08-03 does not meet. The gold contact finish provides superior corrosion resistance compared to tin, and the piston contact architecture offers spring-loaded engagement suitable for repeated mating cycles.

812-22-003-30-007101 is a secondary option with identical electrical and mechanical specifications to the 812-22-003-30-006101 but carries discontinued status at DiGi Electronics, limiting long-term availability assurance.

Both Mill-Max alternatives require confirmation that the receiving connector accommodates piston-type contacts rather than male pin headers. The transition from tin to gold plating and from phosphor bronze to copper alloy represents material changes that may affect long-term reliability in specific environmental conditions; however, both materials meet the same HTSUS classification and export control requirements.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max piston connectors directly replace the Amphenol header in existing designs?

A: Direct mechanical replacement depends on the mating connector type. The 54201-T08-03 is a male pin header designed to mate with female receptacles. The Mill-Max 812 series are piston connectors with spring-loaded contacts. If your application uses standard 2.54mm pitch female receptacles, compatibility is possible; however, the contact engagement mechanism differs. Verify that the receiving connector accepts piston-type contacts.

Q: What is the significance of the contact finish change from tin to gold?

A: Tin plating (100.0µin) on the original part provides adequate corrosion resistance for standard applications. Gold plating (20.0µin) on the Mill-Max alternatives offers enhanced resistance to oxidation and improved electrical conductivity, particularly beneficial in high-reliability or harsh environment applications. The thinner gold layer is standard for piston contacts and does not indicate reduced durability.

Q: Why is the 54201-T08-03 marked as obsolete?

A: Obsolete status indicates that Amphenol ICC has discontinued manufacturing and support for this part. The BERGSTIK® series header has been superseded by newer connector architectures. Existing inventory may be available through authorized distributors, but long-term sourcing cannot be assured.

Q: Are both Mill-Max substitutes equivalent?

A: The 812-22-003-30-006101 and 812-22-003-30-007101 share identical electrical and mechanical specifications. The primary distinction is product status: the 006101 variant maintains active availability, while the 007101 is discontinued at DiGi Electronics. For new designs, the 006101 is the recommended choice due to ongoing supply assurance.

Q: Does the RoHS3 compliance of the substitutes affect compatibility?

A: RoHS3 compliance indicates that the Mill-Max parts meet current environmental and hazardous substance restrictions. The original 54201-T08-03 is RoHS non-compliant, reflecting its obsolete status. If your application or supply chain requires RoHS compliance, the Mill-Max alternatives satisfy this requirement. Mixing compliant and non-compliant components in the same assembly may create supply chain documentation issues; standardization on compliant parts is recommended for new production.

Q: What is the MSL rating, and why is it the same across all three parts?

A: Moisture Sensitivity Level (MSL) 1 (Unlimited) indicates that these connectors have no moisture sensitivity restrictions and do not require special handling, storage, or baking procedures prior to soldering. This rating applies uniformly across all three parts, simplifying logistics and assembly processes.
