Amphenol ICC 10056844-116ALF Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 10056844-116ALF is a shrouded rectangular connector header designed for through-hole mounting applications. This 16-position, 2-row connector operates at 0.100" (2.54mm) pitch and features male pins with gold-plated mating contacts and tin-plated posts. The part is Active status and RoHS Compliant, making it suitable for modern electronic assemblies requiring board-to-board or cable interconnection.

Substitute parts become necessary when the original manufacturer part experiences extended lead times, inventory constraints, or when design flexibility permits equivalent alternatives that meet identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

The Samtec Inc. TST series connectors (TST-108-01-G-D, TST-108-01-L-D, TST-108-01-S-D) qualify as equivalent substitutes for the Amphenol ICC 10056844-116ALF based on the following critical parameters:

Matching Specifications:

16-position, 2-row configuration with 0.100" (2.54mm) pitch and row spacing
Male pin contact type with square contact geometry
Shrouded 4-wall design with push-pull fastening
Through-hole solder termination
UL94 V-0 flammability rating
MSL 1 (Unlimited) moisture sensitivity
Active product status with ROHS3 compliance

Differentiation Parameters: The three TST variants differ in contact finish specifications on the mating and post surfaces, allowing selection based on specific application requirements while maintaining full mechanical and electrical compatibility.

Engineering Selection Recommendations

All three Samtec TST-108-01 variants maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment with the original Amphenol ICC 10056844-116ALF.

TST-108-01-G-D: Gold finish on both mating and post contacts. Select when maximum corrosion resistance and contact durability across all surfaces are required.

TST-108-01-L-D: Gold finish on mating contacts with tin finish on posts. Select for standard applications where mating surface protection is prioritized while post termination uses conventional tin plating.

TST-108-01-S-D: Gold finish on mating contacts with tin finish on posts, featuring thicker mating contact finish (30.0µin vs. 10.0µin). Select when enhanced mating surface durability and wear resistance are specified.

All variants provide equivalent mechanical fit, electrical performance, and board-level compatibility with the original part.

Frequently Asked Questions (FAQ)

Q: Are the Samtec TST-108-01 series connectors mechanically compatible with the Amphenol ICC 10056844-116ALF?

A: Yes. All three variants share identical 16-position, 2-row configuration with 0.100" (2.54mm) pitch, shrouded 4-wall design, and through-hole solder termination. Mating and row spacing dimensions are equivalent, ensuring direct board-level substitution.

Q: What is the primary difference between the three TST-108-01 variants?

A: The variants differ in contact finish specifications. TST-108-01-G-D features gold on both mating and post surfaces. TST-108-01-L-D and TST-108-01-S-D feature gold mating contacts with tin posts, with TST-108-01-S-D providing thicker mating contact plating (30.0µin).

Q: Can I substitute any of the three Samtec variants interchangeably?

A: Yes, from a mechanical and electrical standpoint. Selection should be based on application requirements for contact finish durability and corrosion resistance. All three maintain identical pitch, position count, shrouding, and termination specifications.

Q: What is the operating temperature range for the substitute parts?

A: The Samtec TST-108-01 series operates from -55°C to 125°C. The original Amphenol ICC part does not specify an operating temperature range in the provided data.

Q: Are the substitute parts RoHS compliant?

A: Yes. All three Samtec TST-108-01 variants are ROHS3 Compliant. The original Amphenol ICC 10056844-116ALF is RoHS Compliant.

Q: What is the current rating for the substitute connectors?

A: Each contact in the Samtec TST-108-01 series is rated for 3.4A. The original Amphenol ICC part does not specify a current rating in the provided data.

Q: Do the substitute parts have the same moisture sensitivity level?

A: Yes. Both the original Amphenol ICC 10056844-116ALF and all three Samtec TST-108-01 variants are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions.
