Amphenol ICC 67997-618 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 67997-618 is a rectangular connector header classified as BERGSTIK® II series, featuring 18 positions arranged in 2 rows with 0.100" (2.54mm) pitch. This through-hole solder-terminated component is designed for board-to-board applications with unshrouded, push-pull fastening. The part is marked as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 67997-618 is based on the following critical parameters that must align for functional equivalence:

• Pitch and Position Count: 0.100" (2.54mm) mating pitch with 18 total positions in 2-row configuration
• Connector Type and Contact Type: Header with male pin contacts for board-to-board applications
• Mounting and Termination: Through-hole solder termination with push-pull fastening
• Electrical Performance: 3A current rating and UL94 V-0 flammability compliance
• Environmental Range: Operating temperature capability from -65°C minimum

The identified substitute part 4-103240-0 (TE Connectivity AMP Connectors, AMPMODU Mod II series) shares the core electrical and mechanical characteristics required for substitution. However, this part is available in 80-position configuration, requiring selective use of breakaway sections to achieve the 18-position requirement. Both parts maintain identical mating pitch, contact type, mounting method, and current rating specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 67997-618 and 4-103240-0 are classified as obsolete products. Selection between these parts should be based on the following engineering considerations:

Thermal Operating Range: The 67997-618 supports operation to 130°C, while the 4-103240-0 is rated to 105°C maximum. Applications requiring the extended upper temperature limit must use the original part or identify alternative non-obsolete solutions.

Position Configuration: The 67997-618 is a fixed 18-position connector, while the 4-103240-0 is supplied as an 80-position breakaway header. Implementation of the substitute requires mechanical separation to achieve the 18-position configuration, introducing additional assembly steps and potential mechanical variation.

Contact Material: The 67997-618 uses phosphor bronze contacts, while the 4-103240-0 uses copper alloy. Both materials support the specified 3A current rating and maintain equivalent electrical performance at the mating interface.

Compliance Status: Both parts carry RoHS non-compliant designation and are subject to REACH regulations. Neither part represents a compliance upgrade path for new designs.

Frequently Asked Questions (FAQ)

Q: Can the 4-103240-0 directly replace the 67997-618 without modification?

A: The 4-103240-0 is supplied as an 80-position breakaway header. Direct substitution requires mechanical separation to isolate 18 positions, which introduces assembly complexity not present in the fixed 18-position 67997-618 design.

Q: Are the mating pitch and row spacing identical between these parts?

A: Yes. Both parts maintain 0.100" (2.54mm) mating pitch and 0.100" (2.54mm) row spacing, ensuring mechanical compatibility with mating connectors designed for either part.

Q: What is the impact of the 25°C difference in maximum operating temperature?

A: The 67997-618 supports continuous operation to 130°C, while the 4-103240-0 is limited to 105°C. Applications operating above 105°C require the original part specification.

Q: Are both parts suitable for new designs?

A: Both parts are marked obsolete. New designs should not be based on either part. Current-production alternatives from the same manufacturers should be evaluated for new applications.

Q: Do the contact finish specifications differ between these parts?

A: The 67997-618 specifies gold or gold GXT™ finish, while the 4-103240-0 specifies gold finish only. Both maintain 30.0µin (0.76µm) thickness at the mating interface, ensuring equivalent contact resistance and reliability.

Q: What is the significance of the breakaway feature on the 4-103240-0?

A: The breakaway design allows the 80-position header to be mechanically separated into smaller segments. This feature enables use of a single part number across multiple position count applications but requires post-manufacturing processing for the 18-position requirement.
