Equivalent & Substitute Parts for 54201-S08-03

Part Overview

The Amphenol ICC 54201-S08-03 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 gold plating and solder termination, suitable for board-to-board connections in compact layouts.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 54201-S08-03 is based on the following critical parameters that must align for functional equivalence:

• Pitch (Mating): 0.100" (2.54mm) — determines PCB layout compatibility
• Number of Positions: 3 — defines contact count and connector footprint
• Number of Rows: 1 — establishes single-row configuration
• Mounting Type: Surface Mount — ensures compatible assembly process
• Connector Category: Rectangular Connectors — maintains electrical and mechanical interface standards

The substitute parts identified are Mill-Max Manufacturing Corp. piston connectors from the 812 series. These components maintain the same pitch, position count, row configuration, and surface mount mounting type. While the contact geometry differs (piston vs. male pin header), both designs accommodate the same mating interface spacing and are classified within the rectangular connector category. The substitutes provide active or recently discontinued product status with improved compliance profiles.

Parameter Comparison

Engineering Selection Recommendations

812-22-003-30-006101 is the primary substitute option. This part maintains active product status with ROHS3 compliance and REACH unaffected classification, addressing regulatory requirements that the obsolete 54201-S08-03 does not meet. The component is currently in stock with 641 pieces available. Contact finish thickness is increased to 20.0µin (0.51µm), providing enhanced durability compared to the original 15.0µin specification.

812-22-003-30-007101 serves as a secondary alternative with identical electrical and mechanical specifications to the primary substitute. However, this part is discontinued at DiGi Electronics, limiting long-term availability. Selection of this part should be considered only when 812-22-003-30-006101 is unavailable and existing inventory of 759 pieces meets project requirements.

Both substitutes share the same pitch, position count, row configuration, and surface mount mounting type as the original part. The transition from male pin header to piston connector geometry maintains compatibility with standard 0.100" (2.54mm) mating interfaces. The improved compliance profiles of the substitute parts support modern design requirements and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the 54201-S08-03?

A: The 54201-S08-03 is classified as obsolete. The identified substitutes provide active or recently discontinued product status with improved regulatory compliance (ROHS3 compliant, REACH unaffected) compared to the original part's non-compliant status.

Q: Are the substitute parts mechanically compatible with the original connector?

A: Yes. Both substitute parts maintain the same 0.100" (2.54mm) pitch, 3-position configuration, single-row layout, and surface mount mounting type. These parameters define the mechanical interface and PCB footprint compatibility.

Q: What is the difference between a male pin header and a piston connector?

A: The 54201-S08-03 uses male pin contacts, while the substitute parts use spring piston contacts. Both contact geometries are designed to mate with standard 0.100" (2.54mm) spacing receptacles. The piston design provides spring-loaded contact engagement.

Q: How do the contact finish specifications compare?

A: The original part specifies 15.0µin (0.38µm) gold plating thickness. Both substitute parts provide 20.0µin (0.51µm) gold plating, which exceeds the original specification and offers enhanced contact durability and corrosion resistance.

Q: Which substitute part should be selected for new designs?

A: The 812-22-003-30-006101 is recommended for new designs due to its active product status and current availability. This part provides ROHS3 compliance and REACH unaffected classification, supporting modern regulatory requirements.

Q: What is the difference between the two Mill-Max substitute parts?

A: Both parts are functionally identical with matching electrical and mechanical specifications. The primary difference is product status: 812-22-003-30-006101 is active, while 812-22-003-30-007101 is discontinued at DiGi Electronics. Selection should prioritize the active part for supply chain continuity.

Q: Are there any packaging differences between the substitute parts?

A: The 812-22-003-30-006101 is supplied in tube packaging. The 812-22-003-30-007101 packaging specification is not provided in the available data.

Q: Do the substitute parts meet the same moisture sensitivity requirements?

A: Yes. All three parts share MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints for storage or handling.
