Amphenol ICC 54102-S08-03 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 54102-S08-03 is a vertical through-hole rectangular connector header from the BERGSTIK® series, configured for 6 positions in a 2-row layout with 0.100" (2.54mm) pitch. This connector features male pins with gold-plated mating contacts and phosphor bronze contact material, designed for board-to-board or cable interconnection applications. The part is currently in active product status with 776 units in stock.

Substitute parts are necessary when the original part becomes unavailable, when design requirements shift toward RoHS compliance, or when alternative contact finishes or insulation materials better suit specific application environments. The substitute parts listed maintain electrical and mechanical compatibility through matching pitch, position count, row configuration, and mounting type.

Substitute Part Grouping Explanation

Substitution compatibility for the 54102-S08-03 is determined by the following critical parameters that must remain constant across all alternatives:

Pitch - Mating: 0.100" (2.54mm)
Number of Positions: 6
Number of Rows: 2
Row Spacing - Mating: 0.100" (2.54mm)
Connector Type: Header
Contact Type: Male Pin
Mounting Type: Through Hole

The substitute parts are grouped into two categories based on product status and compliance requirements:

Active Status Substitutes (Recommended for New Designs): TE Connectivity 5-146254-3, 5-146256-3, 5-146257-3, 5-146261-3; Würth Elektronik 61300621121; Samtec TSW-103-07-F-D-LL, TSW-103-07-SM-D, TSW-103-23-F-D

Obsolete Status Substitutes (Legacy Applications): TE Connectivity 104350-3, 146256-3

Variations in contact finish (gold, tin, or mixed finishes), contact finish thickness, insulation material (thermoplastic, liquid crystal polymer, polyamide), contact length specifications, and operating temperature ranges are permitted within the substitution set, as these parameters do not affect mechanical interchangeability or basic electrical function for standard applications.

Engineering Selection Recommendations

For new product designs and applications requiring regulatory compliance, the TE Connectivity 5-146254-3, 5-146256-3, 5-146257-3, and 5-146261-3 are preferred substitutes. These parts carry active product status and RoHS compliance certification (ROHS3 Compliant or RoHS Compliant), addressing modern environmental and regulatory requirements. The Würth Elektronik 61300621121 and Samtec TSW series (TSW-103-07-F-D-LL, TSW-103-07-SM-D, TSW-103-23-F-D) also maintain active status with ROHS3 compliance and extended operating temperature ranges (-55°C to 125°C for Samtec, -40°C to 105°C for Würth).

For legacy applications where RoHS non-compliance is acceptable or where existing inventory must be maintained, the TE Connectivity 104350-3 and 146256-3 remain available as obsolete-status alternatives. These parts maintain full mechanical and electrical interchangeability with the 54102-S08-03.

The selection between active-status substitutes depends on specific application requirements regarding contact finish (gold versus tin), insulation material properties, and operating temperature range. All listed substitutes maintain the critical mechanical parameters: 0.100" pitch, 6-position 2-row configuration, through-hole mounting, and push-pull fastening.

Frequently Asked Questions (FAQ)

Q: Can the 54102-S08-03 be directly replaced with any of the listed substitutes without PCB redesign?

A: Yes. All substitute parts maintain identical pitch (0.100"), position count (6), row configuration (2 rows), row spacing (0.100"), and mounting type (through-hole). Direct footprint compatibility is assured. No PCB layout changes are required.

Q: What is the primary difference between the TE Connectivity AMPMODU Mod II series substitutes?

A: The AMPMODU Mod II substitutes differ primarily in contact finish (gold or tin), contact finish thickness, and insulation material. The 5-146254-3 features tin mating contacts; 5-146256-3 and 5-146257-3 feature gold mating contacts with varying finish thickness (15.0µin versus 30.0µin); 5-146261-3 features gold mating contacts with reduced post length (0.090" versus 0.120"). All maintain identical pitch and position configuration.

Q: Are the Samtec TSW series connectors mechanically compatible with the 54102-S08-03?

A: Yes. The Samtec TSW-103-07-F-D-LL, TSW-103-07-SM-D, and TSW-103-23-F-D maintain the required 0.100" pitch, 6-position 2-row layout, and through-hole solder termination. Minor variations exist in contact post length (0.100" to 0.115" versus 0.120" on the original) and insulation height (0.100" on original and Samtec versus 0.090" on TE Connectivity alternatives), but these do not affect mechanical interchangeability.

Q: Which substitute offers the best RoHS compliance for new designs?

A: The TE Connectivity 5-146254-3, 5-146256-3, 5-146257-3, 5-146261-3; Würth Elektronik 61300621121; and all Samtec TSW variants carry ROHS3 Compliant or RoHS Compliant certification. These are suitable for applications requiring modern environmental compliance. The original 54102-S08-03 is RoHS non-compliant.

Q: What is the difference between the obsolete TE Connectivity 104350-3 and 146256-3 versus the active 5-146256-3?

A: The obsolete 146256-3 and active 5-146256-3 share identical electrical and mechanical specifications but differ in product status and RoHS compliance. The active 5-146256-3 carries RoHS Compliant certification, while the obsolete 146256-3 is RoHS non-compliant. The 104350-3 (obsolete) supports both press-fit and solder termination, whereas the 146256-3 and 5-146256-3 support solder termination only.

Q: Can the 54102-S08-03 be used interchangeably with the Würth Elektronik 61300621121 in high-temperature applications?

A: The Würth Elektronik 61300621121 operates from -40°C to 105°C, which covers the standard industrial range. The original 54102-S08-03 does not specify an operating temperature range. For applications requiring extended low-temperature performance (-55°C), the Samtec TSW series is more suitable.

Q: What packaging options are available for the substitute parts?

A: Packaging varies across substitutes. TE Connectivity 5-146254-3, 5-146256-3, 5-146257-3, 5-146261-3 are supplied in Bulk packaging. Würth Elektronik 61300621121 is supplied in Bulk. Samtec TSW-103-07-F-D-LL and TSW-103-23-F-D are supplied in Bulk and Bag respectively. TE Connectivity 104350-3 and 146256-3 (obsolete) are supplied in Bulk. Packaging does not affect electrical or mechanical function.
