54101-G0820LF Equivalent & Substitute Parts

Part Overview

The 54101-G0820LF is a rectangular connector header manufactured by Amphenol ICC (FCI) in the BERGSTIK® series. This through-hole vertical header connector features 20 positions at 0.100" (2.54mm) pitch with male pins and gold-plated mating contacts. The part is active in production with 1173 units in current inventory. Equivalent and substitute parts are identified to support design flexibility, supply chain continuity, and application-specific requirements where contact finish or packaging preferences differ from the primary specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 54101-G0820LF is determined by the following critical parameters: connector type (header), contact type (male pin), number of positions (20), pitch (0.100" / 2.54mm), number of rows (1), mounting type (through hole), termination method (solder), contact length dimensions, insulation height, operating temperature range (-65°C ~ 125°C), current rating (3A), and material flammability rating (UL94 V-0).

The identified substitute parts maintain these core electrical and mechanical parameters. Variations exist in contact finish (gold versus tin), contact finish thickness, packaging format (bag, bulk, or tube), and insulation material composition. These variations do not affect functional interchangeability in applications where the mating interface, board footprint, and electrical performance requirements are identical.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and comply with RoHS requirements. The 54101-G0820LF features gold plating on mating contacts with a thickness of 30.0µin (0.76µm). The PEC20SAAN from Sullins Connector Solutions provides a direct mechanical and electrical equivalent with tin-plated mating contacts at 100.0µin (2.54µm) thickness and is available in bulk packaging.

The Samtec TS series (TS-120-G-A-1, TS-120-G-A-2, TS-120-G-AA, and TS-120-T-AA) offers gold-plated variants with 20.0µin (0.51µm) contact finish thickness and a tin-plated variant with 200.0µin (5.08µm) thickness. These parts are supplied in tube packaging. The TS-120-G-A-1 and TS-120-G-A-2 are functionally identical gold-plated options, while TS-120-G-AA provides an alternative gold-plated configuration. The TS-120-T-AA offers tin plating for applications where tin contact finish is specified.

Selection between these substitutes depends on contact finish requirements, packaging preferences, and supply chain availability. All parts share identical pitch, position count, mounting type, and termination method, ensuring board-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can the PEC20SAAN replace the 54101-G0820LF directly on the PCB?

A: Yes. Both parts share identical pitch (0.100" / 2.54mm), position count (20), mounting type (through hole), and solder termination. The primary difference is contact finish: the 54101-G0820LF uses gold plating while the PEC20SAAN uses tin plating. This difference does not affect mechanical fit or electrical performance in standard applications.

Q: What is the difference between the Samtec TS-120 variants?

A: The TS-120-G-A-1, TS-120-G-A-2, and TS-120-G-AA are all gold-plated headers with identical electrical and mechanical specifications. The TS-120-T-AA is a tin-plated variant with thicker contact finish (200.0µin versus 20.0µin). All four parts are functionally interchangeable with the 54101-G0820LF at the board level.

Q: Does contact finish thickness affect compatibility?

A: Contact finish thickness does not affect mechanical fit or basic electrical function. The 54101-G0820LF specifies 30.0µin (0.76µm) gold plating on mating contacts. Substitute parts vary in finish thickness but maintain the same contact geometry and current rating (3A per contact).

Q: Are all substitute parts RoHS compliant?

A: Yes. The 54101-G0820LF is RoHS Compliant. All identified substitutes (PEC20SAAN and the Samtec TS series) are ROHS3 Compliant, meeting current regulatory requirements.

Q: What packaging options are available?

A: The 54101-G0820LF is supplied in bag packaging. The PEC20SAAN is available in bulk packaging. The Samtec TS series parts are supplied in tube packaging. Packaging format does not affect component performance but may influence handling and storage procedures.

Q: Can I use a tin-plated part where gold plating is specified?

A: Tin-plated contacts (PEC20SAAN and TS-120-T-AA) provide equivalent electrical performance and mechanical fit. Contact finish selection depends on application requirements, environmental exposure, and corrosion resistance needs. Both finishes are suitable for standard board-to-board connections.
