Amphenol ICC 68020-120 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68020-120 is a through-hole, right-angle rectangular connector header with 20 positions at 2.54mm pitch, designed for board-to-board applications. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system support, maintenance, and new design implementations where legacy compatibility is required.

Substitute Part Grouping Explanation

Substitution of the Amphenol ICC 68020-120 is determined by strict alignment of the following critical parameters:

Position Count Consideration: The main part specifies 20 positions in a 2-row configuration. The identified substitute, TE Connectivity AMP Connectors 4-103149-0, provides 80 positions in a 2-row configuration. This represents a higher-capacity connector within the same pitch and row spacing family, suitable for applications requiring expanded connectivity while maintaining the same fundamental electrical and mechanical interface characteristics.

Electrical and Mechanical Compatibility Criteria:

• Pitch - Mating: 0.100" (2.54mm) - identical
• Row Spacing - Mating: 0.100" (2.54mm) - identical
• Number of Rows: 2 - identical
• Mounting Type: Through Hole, Right Angle - identical
• Termination: Solder - identical
• Contact Type: Male Pin - identical
• Contact Shape: Square - identical
• Contact Finish - Mating: Gold - compatible
• Current Rating: 3A per Contact - identical
• Material Flammability Rating: UL94 V-0 - identical
• Insulation Color: Black - identical

Operational Temperature Variance: The substitute part operates within -65°C ~ 105°C, compared to the main part's -65°C ~ 125°C range. This represents a 20°C reduction in maximum operating temperature.

Contact Geometry Differences: The substitute part features a Contact Length - Post of 0.120" (3.05mm) versus the main part's 0.095" (2.41mm), and an Insulation Height of 0.238" (6.05mm) versus 0.190" (4.83mm). These dimensional variations must be evaluated against specific PCB layout and mating connector specifications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 4-103149-0 serves as a functional substitute for the Amphenol ICC 68020-120 based on alignment of critical electrical and mechanical parameters: identical pitch, row spacing, mounting configuration, termination method, contact type, and current rating.

Both components share identical RoHS non-compliance status and MSL classification, indicating equivalent handling and storage requirements. Both meet UL94 V-0 flammability standards.

Selection of the substitute part requires evaluation of three specific design considerations:

Operating Temperature: Applications requiring sustained operation above 105°C cannot use the substitute part. The main part supports operation to 125°C; the substitute is limited to 105°C maximum.

PCB Layout and Mating Connector Geometry: The substitute part's increased Contact Length - Post (0.120" versus 0.095") and Insulation Height (0.238" versus 0.190") may affect PCB trace routing, component placement clearances, and compatibility with existing mating connectors. Physical verification against PCB layout and mating connector specifications is necessary.

Position Count: The substitute part provides 80 positions versus the main part's 20 positions. Applications utilizing only 20 positions can use the substitute with unused positions left unloaded or populated as required by system design.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 4-103149-0 directly replace the Amphenol ICC 68020-120 in existing designs?

A: Direct replacement is possible if three conditions are met: (1) operating temperature does not exceed 105°C, (2) PCB layout accommodates the increased post length (0.025" longer) and insulation height (0.048" taller), and (3) the mating connector accepts the substitute's dimensional specifications. Physical verification is required before implementation.

Q: What is the primary difference between these two connectors?

A: The main part provides 20 positions while the substitute provides 80 positions. Both share identical pitch (2.54mm), row spacing (2.54mm), mounting type (through-hole right-angle), and current rating (3A per contact). The substitute has a lower maximum operating temperature (105°C versus 125°C) and different contact post geometry.

Q: Are there compliance or certification differences between these parts?

A: Both parts are RoHS non-compliant and carry identical MSL classification (1 - Unlimited). Both meet UL94 V-0 flammability standards. Both carry ECCN EAR99 classification and identical HTSUS codes.

Q: Can I use only 20 positions of the 80-position substitute connector?

A: Yes. The substitute connector can be populated with 20 positions to match the main part's capacity, with remaining positions left unloaded. This approach maintains electrical and mechanical compatibility while utilizing the substitute part's higher-capacity platform.

Q: What contact material differences exist between these parts?

A: The main part uses Phosphor Bronze contacts; the substitute uses Copper Alloy contacts. Both feature gold mating surface finish at 30.0µin (0.76µm) thickness, providing equivalent electrical contact characteristics.
