Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1766664-1 is based on the following critical parameters that must align between the main part and substitute candidates:

Primary Substitution Criteria:

• Connector category classification (Backplane Connectors)
• Connector type and socket configuration (Receptacle, Female Sockets)
• Number of positions (2-position)
• Mounting configuration (Through Hole, Right Angle)
• Termination method (Solder)
• Current handling capability (35A or greater)
• Contact material and finish (Gold)
• Operating temperature range compatibility (-40°C to 105°C or broader)
• Moisture sensitivity level (MSL 1 or equivalent)

The identified substitute part 70239-001LF from Amphenol ICC (FCI) is classified as a coaxial contact connector within the Metral® series. While this part shares certain electrical and mechanical characteristics with the 1766664-1, including gold contact finish, solder termination, and MSL 1 rating, it represents a different connector topology (coaxial pin versus power receptacle socket configuration).

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 1766664-1 is classified as obsolete, which necessitates identification of active alternative components for new designs and ongoing system support. The substitute part 70239-001LF carries an active product status, indicating current manufacturing availability and vendor support.

Compliance and Certification: The 1766664-1 carries a UL94 V-0 material flammability rating and MSL 1 moisture sensitivity classification. The 70239-001LF is RoHS compliant and also carries MSL 1 rating, indicating compatibility with modern environmental and regulatory requirements.

Electrical and Mechanical Compatibility: Both parts feature gold contact finish and solder termination, supporting direct PCB integration. The 70239-001LF exhibits a higher contact finish thickness (50.0µin versus 30.0µin), which may provide enhanced durability in high-cycle applications.

Functional Differences: The primary distinction between these parts lies in connector topology. The 1766664-1 is a power receptacle with female sockets designed for 2-position power distribution at 35A. The 70239-001LF is a coaxial pin connector within the Metral® series. These represent different connector families with distinct mechanical and electrical architectures. Direct substitution requires confirmation that the application requirements align with coaxial contact geometry and performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 70239-001LF directly replace the 1766664-1 in existing designs?

A: Direct substitution requires application-specific evaluation. While both parts share gold contact finish, solder termination, and MSL 1 rating, they represent different connector topologies. The 1766664-1 is a 2-position power receptacle with female sockets, whereas the 70239-001LF is a coaxial pin connector. Mechanical fit, electrical performance, and current distribution characteristics differ between these connector types.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by alignment in the following parameters: connector category, connector type and socket configuration, number of positions, mounting configuration, termination method, current handling capability, contact material and finish, operating temperature range, and moisture sensitivity level. Deviation in any of these parameters may affect functional compatibility.

Q: Why is the 1766664-1 listed as obsolete?

A: The 1766664-1 is classified as obsolete by the manufacturer, indicating that production has been discontinued. This status necessitates identification of active alternative components for system maintenance, repair, and new design implementations.

Q: Does the 70239-001LF meet the same environmental and regulatory standards as the 1766664-1?

A: The 70239-001LF carries RoHS compliance certification and MSL 1 moisture sensitivity rating, aligning with modern environmental standards. The 1766664-1 carries UL94 V-0 material flammability rating. Both parts are suitable for controlled environmental conditions with MSL 1 classification, indicating unlimited shelf life under standard storage conditions.

Q: What is the significance of contact finish thickness differences between these parts?

A: The 1766664-1 features 30.0µin (0.76µm) contact finish thickness, while the 70239-001LF features 50.0µin (1.27µm). Higher contact finish thickness generally provides enhanced wear resistance and durability in high-cycle mating applications. Selection should be based on application-specific cycle life and reliability requirements.

Q: Are there packaging differences between the main part and substitute?

A: The 1766664-1 packaging specification is not provided in the available data. The 70239-001LF is supplied in bulk packaging. Packaging format may affect inventory management, handling procedures, and component preparation for assembly operations.
