54102-T06-20 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 54102-T06-20 is a vertical through-hole rectangular connector header with 40 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This BERGSTIK® series connector is designed for board-to-board or cable applications with male pin contacts, tin-plated mating surfaces, and phosphor bronze contact material. The part is currently active in production with 978 units in stock. Equivalent and substitute parts are necessary when the original part becomes unavailable, when design requirements demand alternative compliance certifications, or when specific contact finishes or insulation materials are required for particular applications.

Substitute Part Grouping Explanation

Substitution eligibility for the 54102-T06-20 is determined by the following critical parameters: 40-position configuration, 2-row arrangement, 0.100" (2.54mm) mating pitch, 0.100" (2.54mm) row spacing, through-hole solder termination, male pin contact type, and board-to-board or cable style. All substitute parts listed maintain these core electrical and mechanical specifications. Variations in contact post length, contact finish composition, insulation material, and compliance certifications are permitted within the substitute group, as these do not affect the fundamental mating interface or electrical performance at the connector level. Contact finish thickness, operating temperature range, and RoHS compliance status are secondary parameters that may differ based on application requirements and manufacturing standards.

Engineering Selection Recommendations

For applications requiring RoHS compliance, substitute parts 7-146256-0, 7-146261-0, M20-9762046, TD-120-G-AA, TSW-120-07-F-D, TSW-120-07-L-D-LL, TSW-120-08-L-D-LC, TSW-120-08-T-D-LC, and TSW-120-09-G-D are suitable alternatives to the RoHS non-compliant 54102-T06-20. Among these, 7-146256-0 and 7-146261-0 are TE Connectivity AMPMODU Mod II series parts with active product status and RoHS compliance. The Samtec TSW series (TSW-120-07-F-D, TSW-120-07-L-D-LL, TSW-120-08-L-D-LC, TSW-120-08-T-D-LC, TSW-120-09-G-D) offers ROHS3 compliance with extended operating temperature ranges and multiple contact post length options for different PCB thickness requirements.

Part 1-104350-7 carries obsolete product status and should be avoided for new designs despite RoHS non-compliance matching the original part. The Harwin M20-9762046 provides ROHS3 compliance with a cuttable connector feature and brass contact material, suitable for applications requiring modular connector configurations.

Contact post length variations across the substitute group accommodate different PCB thicknesses: shorter posts (0.090" to 0.100") for standard PCBs, medium posts (0.120" to 0.122") for thicker boards, and extended posts (0.200" to 0.400") for applications requiring deeper PCB penetration or stacking configurations. Contact finish selection between tin and gold mating surfaces depends on application environment and corrosion resistance requirements.

Frequently Asked Questions (FAQ)

Q: Can TSW-120-09-G-D substitute for 54102-T06-20 in a standard application?

A: Yes. TSW-120-09-G-D maintains the critical mating parameters: 40 positions, 2 rows, 0.100" pitch, and 0.100" row spacing. The primary difference is the extended contact post length (0.400" versus 0.110"), which requires PCB design accommodation but does not affect electrical compatibility at the mating interface.

Q: What is the difference between 7-146256-0 and 7-146261-0?

A: Both are TE Connectivity AMPMODU Mod II series parts with identical mating specifications. The primary difference is contact post length: 7-146256-0 has 0.120" posts while 7-146261-0 has 0.090" posts. Overall contact length differs accordingly (0.440" versus 0.410"). Selection depends on PCB thickness and mounting depth requirements.

Q: Why do some substitute parts have gold mating finishes while the original has tin?

A: Contact finish is a secondary parameter that does not affect mechanical or electrical compatibility at the mating interface. Gold finishes provide enhanced corrosion resistance in harsh environments, while tin finishes are suitable for standard applications. Both finishes meet the 3A current rating and UL94 V-0 flammability requirement.

Q: Is 1-104350-7 recommended as a substitute?

A: No. Although 1-104350-7 maintains the core mating specifications, it carries obsolete product status. Active alternatives with superior compliance certifications are available and should be prioritized for new designs.

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

A: Packaging varies by part: Bulk (standard for most TE and Samtec parts), Tube (TD-120-G-AA), and Bag (TSW-120-07-F-D). Packaging selection does not affect electrical or mechanical performance and is determined by procurement and assembly requirements.

Q: Can M20-9762046 be used in applications requiring standard non-cuttable headers?

A: Yes. M20-9762046 is a cuttable connector, meaning individual positions can be separated if required. This feature does not prevent use in standard applications where the full 40-position header is needed. The connector functions identically to non-cuttable alternatives when used as a complete assembly.

Q: What operating temperature range should be considered when selecting a substitute?

A: The original 54102-T06-20 does not specify an operating temperature range. Substitute parts offer ranges from -40°C to 105°C (M20-9762046) to -55°C to 125°C (Samtec TSW series). Selection should match application thermal requirements; extended range parts provide additional design margin for temperature-sensitive applications.
