Amphenol ICC 54102-S0803LF Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 54102-S0803LF is a rectangular connector header in the BERGSTIK® series, designed for through-hole board-to-board or cable applications. This vertical 6-position connector operates at 0.100" (2.54mm) pitch with male pin contacts and solder termination. The part is currently active in production with 877 units in stock.

Substitute parts are necessary when the original part becomes unavailable, when alternative compliance certifications are required, or when design flexibility permits selection from equivalent connector families that meet identical electrical and mechanical specifications.

Engineering Selection Recommendations

Primary Substitutes (Active Production, Full Compliance):

The TE Connectivity AMPMODU Mod II series parts 5-146254-3, 5-146256-3, 5-146257-3, and 5-146261-3 are recommended as primary substitutes. All are in active production with RoHS compliance and MSL 1 rating. These parts maintain identical pitch, position count, row spacing, contact type, and mounting specifications. Inventory availability ranges from 2,660 to 18,156 units.

The Molex C-Grid 70280 series (0010897061, 0010897062) provides alternative active production options with ROHS3 compliance. Part 0010897061 features tin mating finish, while 0010897062 offers gold mating finish. Both maintain full electrical and mechanical compatibility.

The Würth Elektronik WR-PHD 61300621121 is an active production alternative with ROHS3 compliance and polyamide insulation material. This part supports 250V voltage rating and operates across -40°C to 105°C temperature range.

The Samtec TSW-103-07-F-D-LL offers active production status with ROHS3 compliance and extended operating temperature range (-55°C to 125°C). This part features kinked pin termination and phosphor bronze contact material matching the original part.

Secondary Substitutes (Obsolete, Inventory Available):

The TE Connectivity AMPMODU Mod II parts 104350-3 and 146256-3 are obsolete but available from existing inventory (1,975 and 1,133 units respectively). These parts maintain mechanical and electrical equivalence but are not recommended for new designs due to discontinued production status.

Compliance Considerations:

All substitute parts meet UL94 V-0 flammability requirements and EAR99 export classification. RoHS compliance varies between RoHS Compliant and ROHS3 Compliant designations. For applications requiring specific RoHS generation compliance, verify against design requirements before selection.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 54102-S0803LF with any of the listed parts without PCB redesign?

A: Yes. All listed substitute parts maintain identical mating pitch (0.100"), position count (6), row spacing (0.100"), contact type (male pin), and through-hole solder termination. PCB footprints are mechanically compatible. However, verify contact length specifications if your design has height constraints, as minor variations exist between manufacturers.

Q: What is the difference between the Molex 0010897061 and 0010897062?

A: Both parts are mechanically and electrically identical. The primary difference is mating contact finish: 0010897061 features tin finish (100.0µin thickness), while 0010897062 features gold finish (15.0µin thickness). Select based on your application's corrosion resistance and contact wear requirements.

Q: Why do some substitute parts show "Not Specified" for current rating?

A: The Molex C-Grid 70280 series and Samtec TSW-103-07-F-D-LL do not publish current ratings in the provided specifications. However, all parts are mechanically and electrically equivalent to the 54102-S0803LF, which carries a 3A per contact rating. Contact the manufacturer directly for explicit current rating confirmation if required for your application.

Q: Are the TE Connectivity AMPMODU Mod II obsolete parts (104350-3, 146256-3) suitable for new designs?

A: No. These parts are marked as obsolete and no longer in active production. While inventory is currently available, they should only be used for legacy system maintenance or repair. For new designs, select from the active production alternatives listed in the primary substitutes section.

Q: What is the significance of the operating temperature range differences?

A: The original 54102-S0803LF operates from -65°C to 125°C. Most TE Connectivity AMPMODU Mod II substitutes operate from -65°C to 105°C, representing a 20°C reduction at the upper limit. The Samtec TSW-103-07-F-D-LL maintains the full -55°C to 125°C range. For applications requiring the full -65°C to 125°C specification, verify substitute part temperature ratings against your design requirements.

Q: Do all substitute parts have the same insulation material?

A: No. The original part does not specify insulation material. Substitutes use Liquid Crystal Polymer (LCP), Polyamide (PA6T), or Polybutylene Terephthalate (PBT). All materials meet UL94 V-0 flammability requirements. Select based on your application's thermal and chemical exposure requirements.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the lowest moisture sensitivity level. Parts with this rating have unlimited shelf life under normal storage conditions and do not require special moisture control during handling or assembly. The Würth Elektronik part is rated "Not Applicable," indicating it does not require moisture sensitivity classification.

Q: Can I mix and match substitute parts in the same assembly?

A: Yes. All listed parts are mechanically and electrically interchangeable. However, for manufacturing consistency and supply chain management, it is recommended to standardize on a single part number per design revision.
