Amphenol ICC 55508-338LF Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 55508-338LF is a 38-position receptacle connector in the Minitek® 2.00mm series, designed for board-to-board surface mount applications. This connector features gold-plated mating contacts, a 0.079" (2.00mm) pitch configuration, and operates across the -55°C to 125°C temperature range. With 870 units currently in stock and active product status, this component serves general purpose, industrial, and medical applications requiring reliable dual-row connectivity.

Substitute parts become necessary when addressing supply chain constraints, discontinued product lines, or specific performance requirements that alternative manufacturers can fulfill while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 55508-338LF is determined by strict alignment with the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 38 positions at 0.079" (2.00mm) mating pitch
• Row Configuration: 2 rows with 0.079" (2.00mm) row spacing
• Mounting & Termination: Surface mount with solder termination
• Fastening Mechanism: Push-pull engagement
• Contact Finish: Gold-plated mating surface
• Temperature Range: -55°C to 125°C operation
• Flammability Compliance: UL94 V-0 rating

The identified substitute parts from Samtec Inc. (CLT-119-02-G-D and CLT-119-02-L-D) meet all critical mechanical and electrical parameters. Variations in contact finish thickness, insulation material composition, and current rating per contact represent acceptable engineering tolerances within the rectangular connector category.

Parameter Comparison

Engineering Selection Recommendations

CLT-119-02-L-D (Samtec Inc.) is the primary substitute option. This part maintains active product status, offers higher current capacity per contact (4.1A versus 2A), and provides superior inventory availability (1180 units in stock). The CLT series uses Liquid Crystal Polymer (LCP) insulation material, which delivers enhanced dimensional stability and thermal performance compared to standard plastic formulations. Both parts carry ROHS3 compliance and identical EAR99 export classification.

CLT-119-02-G-D (Samtec Inc.) serves as a secondary substitute with equivalent electrical and mechanical specifications. However, this variant carries discontinued product status at DiGi Electronics, making it unsuitable for new design implementations or long-term supply chain planning.

Both Samtec alternatives demonstrate full compatibility with the 55508-338LF across all critical mechanical interfaces, electrical ratings, and environmental operating parameters. The 0.008" (0.20mm) reduction in insulation height and 5.0µin (0.13µm) reduction in mating contact finish thickness fall within acceptable engineering tolerances for board-to-board connector applications.

Frequently Asked Questions (FAQ)

Q: Can CLT-119-02-L-D directly replace 55508-338LF in existing PCB designs?

A: Yes. Both connectors share identical mating pitch (0.079"), row spacing (0.079"), position count (38), and push-pull fastening mechanism. The 0.008" insulation height difference does not affect PCB footprint compatibility or mating interface geometry.

Q: What is the significance of the higher current rating in the Samtec substitute?

A: The CLT-119-02-L-D supports 4.1A per contact compared to 2A for the 55508-338LF. This represents enhanced current-carrying capacity and does not create compatibility issues. Applications requiring only 2A operation remain fully supported.

Q: How do the insulation materials differ between these connectors?

A: The 55508-338LF uses standard plastic insulation, while CLT-119-02-L-D employs Liquid Crystal Polymer (LCP). LCP provides superior dimensional stability across temperature extremes and improved resistance to moisture absorption, both beneficial for industrial and medical applications.

Q: Are there compliance or certification differences?

A: Both parts carry UL94 V-0 flammability ratings, MSL 1 moisture sensitivity, and EAR99 export classification. The Samtec parts carry ROHS3 compliance versus RoHS compliance for the Amphenol part, representing equivalent or enhanced regulatory alignment.

Q: Why is CLT-119-02-G-D not recommended despite meeting specifications?

A: CLT-119-02-G-D carries discontinued product status at DiGi Electronics, creating supply chain risk for new designs. CLT-119-02-L-D maintains active status with superior inventory availability (1180 units), making it the preferred long-term substitute.

Q: What contact finish options are available in the substitute parts?

A: CLT-119-02-G-D features gold-plated post contacts (3.00µin thickness), while CLT-119-02-L-D uses tin-plated post contacts. Both maintain gold-plated mating surfaces (10.0µin thickness) for reliable signal transmission and corrosion resistance.
